The present invention relates to a resealable lid and cap combination for a container, including the structure, method of manufacturing, and method of use thereof. In general, the resealable lid is assembled to a container such as an aluminum beverage can. The resealable lid includes one or more rotational and axial guide features formed on an interior surface of a container lid sidewall between a seaming panel and a lower edge. The one or more rotational and axial guide features translates a rotational motion into an axial motion as the container cap or other accessory is assembled to the container lid.
The beverage and can industries have long sought to create a can that is both economical to produce and convenient for use by consumers. In the past, beverage cans were provided with a “pull tab” which the consumer would grab by a ring, and pull until the tab was removed from the can. This created a problem in that the tab became disposable waste for which the consumer was responsible to ensure proper disposal. Often the consumer failed to properly dispose of the tab, thereby creating not only litter, but also a safety issue, in that the tabs could be swallowed by small children. Moreover, the edges of the pull tab were sharp enough that they could, if mishandled, cut the fingers or hands of the consumer or anyone else who handled a loose pull tab. As a result of these problems, the industry moved in the direction of a tab that stayed on the can after opening, thereby preventing both litter and any sharp edges from coming into contact with consumers.
The present state of the art is to have a “stay on” tab that is attached to the can lid by a rivet formed in the can lid next to the opening. The opening is formed by a score line, or frangible “kiss cut” which breaks when the tab is pulled up by the consumer. The score line, when broken, produces a hinged flap that stays connected to the can lid, but inside the can.
Beverage cans with stay on tabs suffer from at least the following deficiencies. First, they are not resealable, so that once the consumer opens the beverage; the contents are subject to loss of carbonation, and the influx of foreign material due to the contents being open to the surrounding environment. Secondly, in order to form the rivet which is used to secure the stay on tab to the beverage lid, the lid needs to be made of a different material, typically an aluminum alloy that is stronger than the aluminum alloy used to make the sides and bottom of the can. Further, the tab itself is typically made of a different alloy than the sides and lid, reflecting the need for a still stronger, typically stiffer material. As a result, recycling of the aluminum beverage can is problematic because the different materials need to be separated. The use of three different materials also tends to add complexity, and expense, to the finished container.
A need exists for improved beverage containers that are resealable, cost effective to produce, and “green” in terms of avoiding waste and facilitating the recycling of aluminum cans. Concurrently, a need exists for improved methods for manufacturing beverage containers that result in faster production time, lower production costs, and improved products.
A container has a sidewall and integrally formed bottom. The container is preferably a beverage container, but could be adapted to any suitable container. A top lid includes a socket integrally formed therein; the socket including a generally cylindrical sidewall and a bottom wall. A score line formed in the bottom wall defines a tear panel which forms an opening into the can when the score line is fractured and the tear panel is bent inward or removed. A cap is fitted in the socket and has a sidewall which is formed with cam surfaces. The cam surfaces, formed as grooves or slots, cooperate with bosses or detents formed in the cylindrical sidewall of the socket. The design of the cam surfaces and associated bosses translate the rotational motion of the cap into linear motion, wherein the linear motion fractures the score line and opens the tear panel. As the cap moves downwardly, a protrusion formed on the lower surface of the cap impinges on the periphery of the score line, fracturing the score line and subsequently pushing the tear panel into the can.
Once opened, the cap can be re-fitted into the socket, so that the cam surfaces engage the detents, and are rotated to achieve a sealing position, whereby the contents of the can are protected from the ambient atmosphere. This will result in the prevention of spillage, the loss of carbonation, and the prevention of foreign objects from entering the can. The user can opt to discard the cap and/or container once the entire contents of the can are consumed.

When assembled, the offset projecting incisor 168 is disposed immediately above the cap receiving socket bottom panel circular score line 136, so that when the resealable container cap 160 moves downwardly during opening of the container 100 offset projecting incisor 168 punctures the can at the beginning of the cap receiving socket bottom panel circular score line 136, next to the tear panel hinge 139, then progressively propagates the rupture along the cap receiving socket bottom panel circular score line 136 to its terminus on the opposite end of the tear panel hinge 139.
The cam shaped cap bottom surface 166 may also include a centered projecting incisor 169 disposed on the center axis of the resealable container cap 160 and extending downwardly into the cap receiving socket 130 when the resealable container cap 160 is assembled in the cap receiving socket 130. When assembled, the projection 169 is disposed immediate above a cap receiving socket bottom panel centered “X” shaped score line 142, so that when the resealable container cap 160 moves downwardly during opening of the container, the projection punctures the can at the cap receiving socket bottom panel centered “X” shaped score line 142, thereby relieving internal pressure and assisting in the rupturing of the cap receiving socket bottom panel circular score line 136 by the offset projecting incisor 168.
The opening operation of the container 100 is made possible by forming a cam structure between the cap receiving socket 130 and the resealable container cap 160. In particular, cam groove surfaces 181, 182, 183 are formed in the resealable container cap cylindrical sidewall 162 of the resealable container cap 160. The socket sidewall cam engaging projections 152, 154, 156 are fitted into and engage the cam groove surfaces 181, 182, 183 such that when the resealable container cap 160 is hand-twisted by the consumer, rotational motion of the resealable container cap 160 is converted into linear motion of the resealable container cap 160 thus driving the cap in a downward direction relative to the cap receiving socket 130. As the resealable container cap 160 moves downwardly, the cap receiving socket bottom panel circular score line 136 is ruptured by the offset projecting incisor 168, then progressively propagates the rupture along the cap receiving socket bottom panel circular score line 136 to its terminus. In an alternate embodiment, an optional cap receiving socket bottom panel centered “X” shaped score line 142 may be ruptured by the centered projecting incisor 169 immediately before the cap receiving socket bottom panel circular score line 136 is ruptured by the offset projecting incisor 168, to thereby relieve internal pressure and assist in the rupture of the cap receiving socket bottom panel circular score line 136 by the offset projecting incisor 168.

In the event that the consumer wishes to reseal the container 100, and as shown in
The resealable container cap 160 can be removed again and again to gain access to the contents of the beverage container until all contents are consumed. There is no limit to the type of beverages or other contents that can be housed in the container 100, but most commonly “canned” beverages include sodas, beer, juices, etc. It is also within the scope of the present invention that the contents of the containers could be foodstuff, and non-consumable liquids, gels, powders, and the like.
The cam means disclosed herein can be used for caps that provide other functionality for the container 100. For example, a variation of the resealable container cap 160 would be one that could include a passageway extending through the resealable container cap 160 with drinking implements formed at the upper, outer end, such as a child's sip cup, which would allow a child to drink from the container 100 without spilling. Alternatively, the resealable container cap 160 could be formed with an infant nipple for feeding formula, juice, water or other beverages suitable for infants. When using drinking implements such as sip cup and baby bottle nipples, a resealable container cap 160 would nonetheless have to be employed for opening the container, and then a second “cap” could be used for consuming the contents. In any event, the opening caps and drinking implements could be sold separately from the container 100, as long as the container 100 included the socket sidewall cam engaging projections 152, 154, 156 formed in the cap receiving socket cylindrical sidewall 132 of the cap receiving socket 130.
Although a wide range of plastic materials could be used to form the resealable container cap 160, other materials could be used, including ceramics and metals. However, for harder materials such as these, it may be necessary to position a gasket between the opposing annular surfaces 140, 167 of the socket 130 and the cap 160, respectively to ensure the best possible seal.
While the embodiments described herein place the socket 130 and cap 160 in the top of the container 100, it is possible to have the same opening and resealing structures in the container closed bottom wall 104 of the container 100. Also, while a cylindrical container 100 has been described herein, other shapes of containers, e.g., oval, rectangular, hexagonal, octagonal, and the like, could also be used.
The preferred shape of the frangible cap receiving socket bottom panel circular score line 136 in the bottom of the cap receiving socket 130 is circular, with a closed end and an open end. The inside score (shallower line) terminates in a curve arcing towards the socket's cylindrical sidewall to prevent loss of tear panel into the container. The outside score line (deeper line) terminates in circular form spaced from the inside score line. There is a hinged portion of the tear panel that keeps the panel in contact with the lid once ruptured, as described above.
The offset projecting incisor 168, described as a piercing element, is intended to be a single point of contact that moves deeper, and radially along the inside of the cap receiving socket bottom panel circular score line 136 while the resealable container cap 160 is rotated. The offset projecting incisor 168 may also include additional areas to further drive the cap receiving socket bottom panel tear panel 138 deeper into the container. A single point will apply more force to breaking the cap receiving socket bottom panel circular score line 136 defining the cap receiving socket bottom panel tear panel 138 but additional areas acting in a secondary fashion could help in the opening process.
The socket sidewall cam engaging projections 152, 154, 156 used in the cap receiving socket 130 allow the use of a very shallow socket 130 (as compared to threaded designs) and still provide positive opening, closing and sealing of the resealable container cap 160. The design of the socket sidewall cam engaging projections 152, 154, 156 also provides for positive stops for open, closed and removable cap positions. As seen in
When turning the resealable container cap 160 in the opening direction, e.g., clockwise, the socket sidewall cam engaging projections 152, 154, 156 on the socket's cylindrical sidewall follow the sloped cam groove surface segments 184 of the cam groove surfaces 181, 182, 183, which form gradual ramps, converting the rotary motion of the resealable container cap 160 to a linear or translational movement, which drives the resealable container cap 160 into the interior of the container 100. This engages the offset projecting incisor 168 against the cap receiving socket bottom panel tear panel 138 and provides the force necessary to rupture the cap receiving socket bottom panel circular score line 136. Further turning of the resealable container cap 160 in the opening direction progressively pushes the cap receiving socket bottom panel tear panel 138 out of the way and into the interior of the container 100, until the socket sidewall cam engaging projections 152, 154, 156 reach the closed position of the cam groove surface upper detents 188. A slightly higher point on the sloped cam groove surface segment 184 of the cam groove surfaces 181, 182, 183 just before the closed position provides the resistance necessary to keep the resealable container cap 160 from backing out.
When turning the resealable container cap 160 opposite the opening direction, the socket sidewall cam engaging projections 152, 154, 156 follow the same route to their starting positions but after opening, the socket sidewall cam engaging projections 152, 154, 156 can pass over the transport retaining or cam groove surface lower detents 186 because the stabilizing radially extending cap skirt 170 and the cap receiving socket bottom panel tear panel 138 are now not providing any interference between the transport retaining or cam groove surface lower detents 186 and the void between the cam groove surfaces 181, 182, 183, allowing the resealable container cap 160 to be freed from the container.
In the embodiments described and illustrated herein, the exemplary cam groove surfaces 181, 182, 183 are shown as grooves having a sloped segment that terminates at opposite lower and upper ends in a lower and an upper detent 186, 188 (respectively), whereby the entire cam groove surfaces or elements 181, 182, 183 were formed in the resealable container cap cylindrical sidewall 162 of the resealable container cap 160. It is equally possible to form the cam groove surfaces or elements 181, 182, 183 as projections or bosses from the surface, integrally formed therewith, or as separate parts connected to the resealable container cap 160. Further, while the socket sidewall cam engaging projections 152, 154, 156, acting as cam followers, project from the cap receiving socket cylindrical sidewall 132 of the cap receiving socket 130, the cap receiving socket 130 could have been formed with cam surfaces 181, 182, 183 and the cam followers or cam engaging projections 152, 154, 156 could have been formed on the resealable container cap 160. The exact size and shapes of the cam surfaces 181, 182, 183 can be selected to correspond to the particular needs of the container 100. The overall goal is to select a structure that results in an operable torque which can be applied by consumers without exerting excessive effort.
The structures described above can be made using unique manufacturing processes, which combine some of the known processing steps with new, modified or avoided steps. In one particularly preferred method of making containers 100, as illustrated in the flow chart of
The process described above achieves several cost and environmental advantages over the prior manufacturing techniques. First of all, the lid does not have to be processed to form a rivet, which has conventionally been used to secure a pull tab to a can lid. There is no need for a rivet because there is no need for the pull tab. The rivet required the lid to be made of stronger, thicker material, usually consisting of a different alloy of aluminum as opposed to the material that made up the sidewall and bottom. Moreover, the conventional process would have required the formation of a pull tab, likely to be made of third, different aluminum alloy. Use of three different aluminum materials presented a problem for recycling, whereas in the present invention, a single material can be used to form the can body and the can lid.

An alternative embodiment of a container 200 is shown in
A container closed bottom wall 204 (seen in
A cap receiving socket 230 is formed in the resealable container lid 210 and includes a cylindrical sidewall 110 and a cap receiving socket bottom wall 234. The cap receiving socket 230 is located eccentrically so that it nears a peripheral edge of the resealable container lid 210 to facilitate drinking and pouring after opening. The cap receiving socket 230 further includes a cap receiving socket bottom panel circular score line 236 slightly inset from the peripheral edge of the cap receiving socket bottom wall 234 and forming a cap receiving socket bottom panel substantially closed loop tear panel 238. An cap receiving socket bottom panel centered score line 242 is provided at the center of the bottom wall cap receiving socket bottom wall 234 and preferably includes two intersecting score lines that form an “X” with the intersection of the two lines being at the center of the cap receiving socket bottom wall 234. The cap receiving socket bottom wall 234 further includes socket bottom panel ramps 290, 291, 292 which are equidistantly spaced around the periphery of the cap receiving socket bottom wall 234 inside the cap receiving socket bottom panel circular score line 236. A different number of ramps could be used, but three is preferable. The socket bottom panel ramps 290, 291, 292 are integrally formed in the cap receiving socket bottom wall 234.
The cap receiving socket 230 further includes equidistantly spaced socket sidewall cam engaging projections 252, 254, 256 (examples of container lid rotational and axial guide features) formed in the sidewall 110. From an interior view, such as that shown in
A resealable container cap 260 fits into the cap receiving socket 230 and includes a resealable container cap cylindrical sidewall 262 and a bottom wall 136. A series of cam groove surfaces 281, 282, 283 (examples of container cap rotational and axial guide features) are provided in the resealable container cap cylindrical sidewall 262 of the resealable container cap 260 at equidistantly spaced locations and are designed to receive the cam engaging projections 252, 254, 256, respectively, of the cap receiving socket 230, when the resealable container cap 260 is assembled within the cap receiving socket 230. In this regard, the embodiment of container 200 is similar to that of the embodiment of container 100. When assembled and before opening the container, the resealable container cap 260 seats in the cap receiving socket 230 as shown in
The resealable container cap 260 further includes a resealable container cap handle or grip element 274 at the upper end of the resealable container cap 260 so that the consumer can turn the cap in either clockwise or counterclockwise directions. As in the previous embodiments, the upper perimeter of the resealable container cap 260 is provided with a radially extending cap skirt 270 which provides a tamper resistant feature, whereby the skirt would extend upwardly if the cap had been turned to cause the resealable container cap 260 to descend further into the cap receiving socket 230. The radially extending cap skirt 270 and all other features of the resealable container cap 260 are integrally formed in a one-piece construction preferably of a plastic material. Within the scope of the invention, other materials could be used including ceramic and metallic materials.
A sharp centered incising projection 269 is formed in the center of the bottom surface of the resealable container cap 260, so that when the resealable container cap 260 is fitted in the cap receiving socket 230, prior to opening the beverage can 100, the point of the sharp centered incising projection 269 is positioned next to or juxtaposed at the center of the bottom surface of the cap receiving socket 230, at the point of intersection between the two lines that form the cap receiving socket bottom panel centered score line 242. The sharp centered incising projection 269 punctures the cap receiving socket bottom wall 234 of the cap receiving socket 230 as the resealable container cap 260 moves linearly downwardly and further into the cap receiving socket 230 during opening operation of the beverage can 200.
An offset projecting incisor 268 is formed along an outer region of the bottom surface of the resealable container cap 260, so that when the resealable container cap 260 is fitted in the cap receiving socket 230, prior to opening the beverage can 100, the point of the sharp offset projecting incisor 268 is positioned in alignment with the cap receiving socket bottom panel circular score line 236 formed in the bottom surface of the cap receiving socket 230, as best shown in
To understand how the embodiment of container 200 operates, reference is made to
After the resealable container cap 260 is rotated or turned to the full extent allowed, the resealable container cap 260 pushes the cap receiving socket bottom panel loop tear panel 238 into the can, but the tear panel 238 stays connected to the resealable container lid 210 through a portion of the lid between the ends of the cap receiving socket bottom panel circular score line 236. In order to then drink the contents of the container 200, the consumer turns, twists or rotates the resealable container cap 260 in the opposite direction until returning past the starting point from where the opening rotation started, placing the cam engaging projections 252, 254, 256 in the opened area of the cam groove surfaces 281, 282, 283.
At that point, the resealable container cap 260 is pulled upwardly by the consumer to become separated from the container 200, and the consumer is then free to drink from the opening formed in the resealable container lid 210 as a result of the cap receiving socket bottom panel substantially closed loop tear panel 238 being pushed into the container 100. When the consumer is finished drinking, and if the container 200 is not empty, the consumer can reseal or close the beverage container by pushing the resealable container cap 260 back into the cap receiving socket 230 and then turning, twisting or rotating the resealable container cap 260 in the same direction as the opening direction, until the resealable container cap 260 is fully seated in the cap receiving socket 230, thus sealing the opening in the container 200. In the resealed state, the contents of the container 200 can be kept fresh, carbonated (in the case of carbonated drinks), and spill-proof (when the beverage container 200 is mobile, such as if kept in a back pack, stroller, automobile drink holder, and the like).
As in the other embodiments described herein, the invention includes an assembled container 200, with or without contents, with a unique resealing mechanism. The invention also includes a container subassembly comprising a resealable container lid 210 and a resealable container cap 260, capable of further assembly with a container body 202, 204, such as beverage containers commonly in use as aluminum cans for distribution of a wide variety of beverages. The invention further includes a resealable container cap 260 capable of use with a resealable container lid 210, or with a container 200 that includes a resealable container lid 210, such that the beverage containers could be purchased without resealable container caps 260, and could separately purchase resealable container caps 260 that are then used with the containers 200 that are formed with the aforementioned cap receiving socket 230. This way, resealable container caps 260 could be re-used, repeatedly. Purchase of resealable container caps 260 separately from the containers 200 would have a “green” effect, in that the resealable container caps 260 could be washed and re-used over and over, thereby reducing waste.
Another feature of the invention is to provide a resealable container cap 360, as illustrated in
A central sharp projection 241 is formed in the center of the bottom surface of the resealable container cap 360, wherein the central sharp projection 241 is similar to the sharp centered incising projection 269 described above in design, location and function.
An offset projecting incisor 368 is formed along an outer region of the bottom surface of the resealable container cap 360, wherein the offset projecting incisor 368 is similar to the offset projecting incisor 268 described above in design, location, and function.
Any of a variety of thermoplastic elastomers (TPEs) can be used to make the cap sealing ring 365, and selection of the precise one is a matter of design choice, as the requirements are simply that the material be easy to mold, easily adherent to the material that makes up the cap, and to some degree deformable under pressure (in use). Other materials could be used if a sealing ring is pre-made and adhesively bonded to the end face or bottom wall of the cap. However, molding the ring in place is preferred. As for TPEs, they are sometimes referred to as thermoplastic rubbers, and are in a class of copolymers or a mixture of polymers which consist of both thermoplastic and elastomeric properties. They are particularly suitable for injection molding, which is the preferred way to form the cap sealing ring 365 on the face of the resealable container cap 360.
It is noted that in
The resealable container cap 360 operates in the same way as the caps of previous embodiments, in that the consumer turns the cap in one direction to open the container, then turns the resealable container cap 360 in the opposite direction to remove the resealable container cap 360, and then the resealable container cap 360 is re-inserted into the cap receiving socket 230 and turned in the first, container-opening direction until the resealable container cap 360 is fully seated in the cap receiving socket 230. The resealable container cap 260 is shown in this fully seated position in
In the previously described embodiments, the cap is provided with a resealable container cap handle or grip element 174, as seen in
Referring now to
Using the same principals of material flow or deformation during the pressing steps, a score line thinned fracture initiation region 437 is formed at one end of the cap receiving socket bottom panel circular score line 436 where one of the ramps 394, 395, 396 in conjunction with ramps 490, 491, 492 will impinge upon the score line 436. At the beginning of the opening process, the ramps 394, 395, 396 in conjunction with ramps 490, 491, 492 push on the flared, score line thinned fracture initiation region 437, which has been thinned essentially to the thickness of the sidewall 102, 202 of the container 100, 200, in the case of an aluminum can. In other words, the entire area of the puncture area is thinned relative to the surrounding surface of the lid 410 to make it easier to puncture or break the score line 436. Once the score line 436 is broken at the puncture area 437, the break will propagate more readily and predictably around the score line 436 to ease the opening of the container 100, 200. Although the score line thinned fracture initiation region 437 is thinner, and thus potentially more vulnerable to accidental opening, it is no thinner than the sidewall of the beverage container and thus capable of withstanding internal pressures. It is also shielded from accidental external rupture by means of the cap 460 when seated in the socket 430.
Each embodiment described herein has referred to a tear panel, such as cap receiving socket bottom panel tear panel 138, as that part of the bottom wall of the socket that is defined by a circular or loop-shaped score line. This tear panel can also be described as a “frangible area” because it breaks away from the rest of the bottom wall 138, 238, 338, 438 when the cap 160, 260, 360, 460 descends into the socket 130, 230, 330, 430. It is not required, however, for the tear panel 138, 238, 338, 438 or frangible area to be substantially circular or looped in shape, and indeed, a second illustrated embodiment is shown in
During opening and closing operations, the resealable container cap handle or grip element 274, 474 is turned preferably ninety degrees (90°) in one direction, and then to withdraw the resealable container cap 260, 360, 460 from the socket, the grip 274, 474 is turned ninety degrees (90°) in the opposite direction, to the beginning point. In order to remove the resealable container cap 260, 360, 460 altogether from the lid, the grip is turned approximately another ten degrees (10°) until the grooves and protrusions are separated and the resealable container cap 260, 360, 460 is free to be lifted upwardly away from the container. Different combinations of embossed ramps 390, 392 and de-bossed ramps 391, 393, and different numbers of ramps, can be employed to achieve the desired effect. The space between the resealable container cap 260, 360, 460 and the cap receiving socket bottom wall 234, 334 of the cap receiving socket 230, 330, 430 is equal to the length of linear travel when the resealable container cap 260, 360, 460 is operated between the transport and open/resealed positions (in the case of aluminum beverage cans, approximately 0.055 inches). With the use of ramps that are embossed on the tear panel 238, 338, 438 that distance can be doubled, forcing the tear panel 238, 338, 438 to fold on its hinge 239, 339, 439 further away from the opening.
In all cases using ramps, it is preferred that the peak height of the ramps be disposed near or in close proximity to the hinge, as this will help push the tear panel 238, 338, 438 out of the way when the cap's cam body pushes through the opening. The ramps help propagate the ruptured score line along its length. There are corresponding ramps or other structures on the bottom of the cap that will interface with ramps on the tear panel 238, 338, 438 or panels. All ramps are embossed (rise up from the bottom socket surface), but they could equally be de-bossed ramps 391, 393 that start below the bottom socket surface and continue up the embossed ramp 390, 392. If the respective ramp on the cap starts inside the debossed ramp on the lid 210, 310, 410, during operation the effective linear travel of the cap 260, 360460 can be doubled, tripled, and perhaps quadrupled.
A resealable container lid 510, illustrated in
The resealable container lid 510 is preferably formed from a single sheet of metal using any suitable metal forming process or combination of metal forming processes. The resealable container lid 510 is formed having a substantially vertical sidewall 522, 532 and a generally horizontally arranged cap receiving socket bottom wall 534. The substantially vertical sidewall 522, 532 is configured having a cylindrical shape extending between an upper peripheral edge and a lower peripheral edge.
In previous variants, a cap receiving socket 130 was formed extending downward from a portion of the resealable container lid planar base bottom 119. More specifically, the cap receiving socket 130 is defined by a cap receiving socket cylindrical sidewall 132 in combination with the cap receiving socket bottom wall 134. The cap receiving socket 130 is preferably located off-centered respective to a peripheral edge of the resealable container lid 110.
In the exemplary variant, a cap receiving socket is defined by the cap receiving socket cylindrical sidewall 532 in combination with the cap receiving socket bottom wall 534. More specifically, the resealable container lid 510 is formed deeper to include the cap receiving socket cylindrical sidewall 532 as part of the outer peripheral sidewall, making the cap receiving socket bottom wall 534 the same as the container lid planar base bottom 119. The cap receiving socket is concentrically arranged respective to the cap receiving socket cylindrical sidewall 532 of the resealable container lid 510. A peripheral countersink 526 provides a transition between the cap receiving socket cylindrical sidewall 532 and the cap receiving socket bottom wall 534. The peripheral countersink 526 is preferably formed having a generally “U” shape, extending downward from the cap receiving socket cylindrical sidewall 532, then radially inward arching from a downward direction to an upward direction, and extending upward where the peripheral countersink 526 transitions into a peripheral edge of the cap receiving socket bottom wall 534.
The peripheral countersink 526 extends downward below an upper surface of the cap receiving socket bottom wall 534. The peripheral countersink 526 provides a clearance for a lower region of a resealable container cap cylindrical exterior sidewall 562 of the resealable container cap 560 during assembly of the resealable container cap 560 and the resealable container lid 510 to one another.
The resealable container lid 510 includes a number of functional features. A seaming panel 520 (alternatively referred to as a lid and container joining formation 520) is formed about an upper edge of the resealable container lid 510, wherein the seaming panel 520 is provided to assemble the resealable container lid 510 to a container seaming flange 106 (
A cap receiving socket bottom panel tear panel 538 is designed into the resealable container lid 510 enabling the user to access the contents stored within the container. The cap receiving socket bottom panel tear panel 538 is defined by a cap receiving socket bottom panel circular score line 536 formed within the cap receiving socket bottom wall 534 of the resealable container lid 510. The cap receiving socket bottom panel tear panel 538 can be formed in at least one of a top surface of the cap receiving socket bottom wall 534 and a bottom surface of the cap receiving socket bottom wall 534. The cap receiving socket bottom panel circular score line 536 can be routed in any suitable shape defining the cap receiving socket bottom panel tear panel 538. In the exemplary embodiment, the cap receiving socket bottom panel circular score line 536 is formed extending between two ends in a generally circular shape. The two ends are spatially arranged creating a tear panel hinge 539. At least one end can be configured extending outward from an interior region or cap receiving socket bottom panel tear panel 538 defined by the cap receiving socket bottom panel circular score line 536. The at least one outward extending end of the cap receiving socket bottom panel circular score line 536 deters against tearing of the material between the two ends of the cap receiving socket bottom panel circular score line 536. It is understood that the preferred cap receiving socket bottom panel circular score line 536 would include a configuration where both ends include the outward extending formation. The outward extending formation can be linear, arched, or of any other suitable shape. In the exemplary embodiment, the cap receiving socket bottom panel tear panel 538 is designed to open when the resealable container cap 560 is rotated in a counterclockwise direction, wherein the opening is defined as a dispensing aperture. The dispensing aperture can be sized to dispense a beverage and/or a food product, wherein the beverage and/or food product are collectively referred to as comestible. The exemplary embodiment is directed towards a container adapted for retaining, distributing, and consuming a beverage, such as water, carbonated drinks, fruit drinks, milk, beer, wine, and the like. It is understood that the same container lid 510 can be used for smaller food products, such as peanuts and other nuts, candy, mints, gumdrops, confections, jelly beans, condiments, soups, oils, spices, powdered products (baking soda, sugar, flour), and the like.
A seaming chuck shoulder 524 can be formed about a central portion of the vertical wall, segmenting the wall into a seaming chuck wall 522 (upper portion) and a cap receiving socket cylindrical sidewall 532 (lower portion). A plurality of cam tracks 552, 554, 556 (examples of container lid rotational and axial guide features) is formed within the cap receiving socket cylindrical sidewall 532. The plurality of cam tracks 552, 554, 556 is spatially arranged about the cap receiving socket cylindrical sidewall 532. The plurality of cam tracks 552, 554, 556 run generally horizontally, having slight upward and/or downward deviations to accomplish upward and/or downward motions of the resealable container cap 560. The cam tracks 552, 554, 556, provide several functions, including rotational and axial motions between the resealable container lid 510 and the resealable container cap 560, reinforcement of the vertical wall, a retention mechanism for retaining the resealable container cap 560 within the cap receiving socket of the resealable container lid 510, and other functions. The cam tracks 552, 554, 556 are segmented functionally into a plurality of sections, as shown in
A resealable container lid upper surface reinforcement formation 518 can be included and would be formed as either an embossed feature or a debossed feature within the cap receiving socket bottom wall 534. The resealable container lid upper surface reinforcement formation 518 is defined by a socket bottom wall to surface reinforcement formation transition 541. The cap receiving socket bottom panel tear panel 538 would be located within the resealable container lid upper surface reinforcement formation 518. The resealable container lid upper surface reinforcement formation 518 would be shaped to support the material of the resealable container lid upper surface reinforcement formation 518 adjacent to the cap receiving socket bottom panel circular score line 536 to increase the efficiency of the propagation of the fracture when the opening force is applied by the resealable container cap 560 onto the associated features of the cap receiving socket bottom panel tear panel 538. In addition, the resealable container lid upper surface reinforcement formation 518 provides a clearance for an incisor deboss panel 566 on the resealable container cap 560 and the resealable container lid upper surface reinforcement formation 518 lowers the top surfaces of the lead in supplemental score fracture propagation and tear panel support boss 597, the tear panel reinforcing boss 598, and the finishing score fracture propagation and tear panel fold urging boss 593 of the cap receiving socket bottom panel tear panel 538 resulting in a clearance to the bottom surface of the resealable container cap planar traversing wall 564 of the resealable container cap 560. The incisor deboss panel 566 is described as such as when viewing from an exterior surface of a resealable container cap 560 formed from a single sheet of material, the incisor deboss panel 566 appears as a recession extending downward from the resealable container cap planar traversing wall 564. In an alternative description, the incisor deboss panel 566 can be referred to as an incisor platform 566, as the incisor platform 566 extends downward from a bottom surface of the resealable container cap planar traversing wall 564.
The resealable container lid 510 can include one or more features to reinforce desired areas of the resealable container lid 510.
Reinforcement features can be integrated into the cap receiving socket bottom wall 534 and/or the vertical sidewall. The reinforcement features can provide any of several functions, including retention of a shape of the associated segment of the resealable container lid 510, movement between the resealable container cap 560 and the resealable container lid 510, reinforcement during initiation and/or propagation of a fracture of a cap receiving socket bottom panel circular score line 536, clearance for features during operation, retention of the resealable container cap 560 within the cap receiving socket of the resealable container lid 510, and the like.
The seaming chuck shoulder 524 provides some rigidity to the vertical sidewall. The cam tracks 552, 554, 556 provide additional rigidity to the vertical sidewall. The peripheral countersink 526 provides support about the lower edge of the vertical sidewall and the peripheral edge of the cap receiving socket bottom wall 534. The peripheral countersink 526 introduces some flexibility between the lower edge of the vertical sidewall and the peripheral edge of the cap receiving socket bottom wall 534, which will be described in more detail when discussing a retort process.
As stated above, the socket bottom wall to surface reinforcement formation transition 541 (defining the resealable container lid upper surface reinforcement formation 518) supports the portion of the resealable container lid upper surface reinforcement formation 518 adjacent to the cap receiving socket bottom panel circular score line 536 to increase the efficiency of the propagation of the fracture when the opening force is applied by the resealable container cap 560 onto the associated features of the cap receiving socket bottom panel tear panel 538.
An incisor pathway channel 517 can be formed within the resealable container lid upper surface reinforcement formation 518. The incisor pathway channel 517 is preferably formed having a semi-circular, debossed shape concentric with an axis of rotation of the resealable container cap 560. One end of the incisor pathway channel 517 terminates at an incisor channel to tear panel surface transition 592, wherein the incisor channel to tear panel surface transition 592 is located proximate and/or abutting a fracture initiating region of a cap receiving socket bottom panel circular score line 536. The incisor pathway channel 517 provides several functions, including increasing a rigidity of the resealable container lid upper surface reinforcement formation 518 and providing a clearance for an incisor 568 during rotation of the resealable container cap resealable container cap 560, wherein the offset projecting incisor 568 extends downward from a lower surface of the resealable container cap 560.
The exemplary embodiment includes a series of ribs 593, 597, 598 for reinforcing the cap receiving socket bottom panel tear panel 538. These formations reinforce the cap receiving socket bottom panel tear panel 538 in both a radial direction and a tangential direction respective to a rotational motion of the resealable container cap 560. The series of ribs 593, 597, 598 transfers and distributes a force applied by features of the resealable container cap 560 across the cap receiving socket bottom panel tear panel 538, directing the applied force to the cap receiving socket bottom panel circular score line 536, propagating a fracturing of the cap receiving socket bottom panel circular score line 536 along a length of the cap receiving socket bottom panel circular score line 536.
In addition to the above described reinforcing features, the lower edge of the resealable container cap cylindrical exterior sidewall 562 can be rolled to reinforce the circumferential lower edge thereof, as well as eliminating any sharp edges of the resealable container cap 560.
The resealable container cap 560 can be formed in any suitable configuration, with several variations of the container cap being described herein. Each of the variants of the container caps can be fabricated of any suitable metal, aluminum, steel, plastic, composite materials, fiber reinforced plastics, or any other suitable material. The exemplary resealable container cap 560 is formed from a single sheet of material using at least one commonly known metal forming process or other manufacturing process associated with the selected material.
The exemplary resealable container cap 560 includes a vertical sidewall circumscribing a peripheral edge of a resealable container cap planar traversing wall 564. The vertical sidewall includes an upward extending resealable container cap cylindrical interior sidewall 563 and a downward extending resealable container cap cylindrical exterior sidewall 562. The upward extending resealable container cap cylindrical interior sidewall 563 and the downward extending resealable container cap cylindrical exterior sidewall 562 are generally perpendicular to a resealable container cap planar traversing wall 564.
A cylindrical sidewall inverted countersink 570 is formed about an upper end of the vertical sidewall, the cylindrical sidewall inverted countersink 570 being a transition between the resealable container cap cylindrical interior sidewall 563 and the resealable container cap cylindrical exterior sidewall 562. The cylindrical sidewall inverted countersink 570 can be formed having an inverted “U” shape. The resealable container cap cylindrical exterior sidewall 562 is preferably dimensioned so that it fits within a generally vertical clearance between the proximal surfaces of the cam tracks 552, 554, 556 and the peripheral edge of the cap receiving socket bottom wall 534 (essentially, an inner wall of the peripheral countersink 526). Additionally, the resealable container cap cylindrical exterior sidewall 562 is preferably designed so that it curves out towards the cap receiving socket cylindrical sidewall 532, closing the gap created between the cap receiving socket cylindrical sidewall 532 and resealable container cap cylindrical exterior sidewall 562 to provide clearance for the cam tracks 552, 554, 556. It is understood that by closing this gap the container lid assembly can decrease the possibility of contaminants entering the gap between the cap receiving socket cylindrical sidewall 532 and resealable container cap cylindrical exterior sidewall 562.
An offset projecting incisor 568 extends downward from a bottom surface of the resealable container cap planar traversing wall 564. The offset projecting incisor 568 can be located within a incisor deboss panel 566, wherein the incisor deboss panel 566 is a debossed feature providing several functions, including lowering the offset projecting incisor 568, reinforcing an area of the material surrounding the offset projecting incisor 568, a distributed compression force applicator, and other functions.
A ring shaped cap sealing ring 565 is applied to a peripheral edge of a bottom surface of the resealable container cap planar traversing wall 564. The cap sealing ring 565 is fabricated of any suitable pliant material, including an elastomer, an elastomeric polymer, plastisol, a low durometer rubber, or any other suitable pliant sealing material.
A series of cam followers 581, 582, 583 are spatially arranged along a lower edge of the resealable container cap cylindrical exterior sidewall 562. The cam followers 581, 582, 583 are preferably formed using any suitable metal forming process, such as crimping process. The cam followers 581, 582, 583 would be sized and spatially arranged and located to be in alignment with the respective inter-cam relief sections 551, 555, 553. The cam followers 581, 582, 583 are sized and spatially arranged to pass through each respective inter-cam relief section 551, 555, 553 for engagement with a lower surface of the respective cam track 552, 554, 556. The interaction between the cam followers 581, 582, 583 and the respective cam track 552, 554, 556 converts a rotational motion of the resealable container cap 560 within the cap receiving socket of the resealable container lid 510 into at least one of an axial motion and an axial force applicator. The peripheral countersink 526 of the resealable container lid 510 is sized and shaped to receive the bottom edge of resealable container cap cylindrical exterior sidewall 562 and the cam followers 581, 582, 583 formed on the bottom edge of resealable container cap cylindrical exterior sidewall 562.
At least one resealable container cap grip element 574 is formed extending upward from the top surface of the resealable container cap planar traversing wall 564 of the resealable container cap 560. The resealable container cap grip element 574 can be formed having any suitable shape. In a preferred embodiment, the resealable container cap grip element 574 would be of a height that retains a top edge of the resealable container cap grip element 574 at or below a top edge or surface of the seam of the container (container body and lid assembly seam 509 of
The resealable container cap grip element 574 would include at least one cap grip element force application surface 575. The cap grip element force application surface 575 would be sized to ergonomically and adequately support a force applied by the end user.
The user would grip each at least one cap grip element force application surface 575 to apply a force to the resealable container cap 560. The force is translated into a rotational or torsional force for urging the resealable container cap 560 into a counterclockwise (score line fracturing) motion or a clockwise (closing) motion. In more detail, the cam tracks 552, 554, 556 are segmented into a plurality of functional sections, as best shown in
The assembly requires a significant downward force in combination with a counterclockwise rotation, compressing a cap sealing ring 565 sufficiently enough to locate the first formed cam follower 581 along a bottom edge of the cam track assembly/locking detent segment 552A of the first socket cam track 552. The significant downward force compresses the cap sealing ring 565, as shown in
The cam track assembly/locking detent segment 552A retains the resealable container cap 560 within the cap receiving socket of the resealable container lid 510, when subjected to a clockwise motion. The offset projecting incisor 568 butts up against the incisor channel to tear panel surface transition 592 to retain the resealable container cap 560 within the cap receiving socket of the resealable container lid 510, when subjected to a continuing counterclockwise motion. Registration between the offset projecting incisor 568 and the incisor channel to tear panel surface transition 592 is best shown in
The initial assembly step is adapted for completion by a mechanical device, such as an assembly machine. The forces required are designed to deter accomplishment of the initial assembly step by an individual. The subsequent steps are adapted to be accomplished by the end user.
The following describes the container lid opening sequence, which is directed towards completion by the end user. Continuing with a counterclockwise rotation of the resealable container cap 560, from a position where the first formed cam follower 581 is engaged with the cam track initial/resealed segment 552B, the continuing motion causes the offset projecting incisor 568 to impinge upon the incisor channel to tear panel surface transition 592, initializing a fracture of the cap receiving socket bottom panel circular score line 536, as shown in
As the rotation continues, the first formed cam follower 581 transitions from the cam track initial/resealed segment 552B to a cam track height transition segment 552C, as best shown in
As the rotation continues, the offset projecting incisor 568 rides up tear panel surface incisor pathway to tear panel fold boss transition 590, as shown in
Nearing the end of the rotational container lid opening sequence, just prior to the transition of the first formed cam follower 581 between the cam track operating segment 552D to a cam track cam follower leader section 552E, shown in
The shape of the cam tracks 552, 554, 556, more specifically, the cam track cam follower leader section 552E, is designed such to provide a clearance between the bottom of the offset projecting incisor 568 and the top surface of the resealable container lid upper surface reinforcement formation 518 to avoid any binding or other interference of the rotation of the resealable container cap 560. The combination of the cam track assembly/locking detent segment 552A and cam track cam follower leader section 552E ensures the reinstallation of the resealable container cap 560 into the cap receiving socket is only in a clockwise direction. Additionally, the revised, opened configuration of the resealable container lid 510 enables the user to insert the resealable container cap 560 into the cap receiving socket to reseal the resealable container 500 in any of the three potential orientations. The incisor pathway channel 517 provides clearance for the offset projecting incisor 568 in any orientation. The associated cam follower 581, 582, 583 is rotated to engage with the respective sealing section of the cam track 552, 554, 556 (as referenced by cam track initial/resealed segment 552B of the first socket cam track 552), causing the cap sealing ring 565 to compress against the top surface of the cap receiving socket bottom wall 534, providing an air and liquid tight seal therebetween.
In addition to the operational features, the resealable container cap 560 can include a tamper indicator, such as the off-center tamper indicator feature 528, shown in
Another feature of the configuration of the resealable container lid 510 and resealable container cap 560 is an anti-missiling function. Missiling may occur upon an initial fracture of the cap receiving socket bottom panel circular score line 536, releasing stored pressure from within the resealable container 500. In a condition where the resealable container cap 560 retains a seal against the resealable container lid 510 and the resealable container lid 510 is breached, the pressure released from the resealable container 500 could potentially cause the resealable container cap 560 to become a projectile. The anti-missiling feature is created by a separation between the cap sealing ring 565 and the top surface of the cap receiving socket bottom wall 534 while the resealable container cap 560 remains in engagement with the resealable container lid 510 during the initial opening sequence of the resealable container 500, thus providing a pathway for release of pressure.
As previously mentioned, the resealable container cap 560 can be designed in any of a variety of configurations. A resealable container cap 660, illustrated in
The resealable container cap 660 includes features that are similar to those of the resealable container cap 560. Like features of the resealable container cap 660 and the resealable container cap 560 are numbered the same except preceded by the numeral ‘6’. The significant distinction of the resealable container cap 660 is the location of the concentric tamper indicator feature 628. The off-center tamper indicator feature 528 is formed in an off-centered location respective to a centroid of the resealable container cap 560. Conversely, the concentric tamper indicator feature 628 is formed in a concentric about the centroid of the resealable container cap 660. The centered location of the concentric tamper indicator feature 628, and more specifically, the concentric tamper indicator operation element 629 of the concentric tamper indicator feature 628, is located to contact the resealable container lid upper surface reinforcement formation 518 of the resealable container lid 510, as illustrated in
An assembly of the resealable container lid 510 onto the container cylindrical sidewall 102 was previously introduced, but not fully described. The assembly process is described in a series of sequence illustrations shown in
A seaming chuck tool 600 is inserted into an interior of the resealable container lid 510 defined by the interior surface of the seaming chuck wall 522. The resealable container lid 510 is seated upon the container seaming panel 106 and the container seaming wall 108 of the container cylindrical sidewall 102, as shown in
A first operation roller driving channel first operation roller driving channel 606, formed in a contacting surface of the first operation roller 604, rolls the seaming panel 520 and the respective portion of the container seaming panel 106, as shown in
In a preferred process, the second/final operation roller 607 rotates about a second (final) operation roller spin axis 608 and the seaming chuck tool 600 rotates the container cylindrical sidewall 102 and the associated resealable container lid 510 against the second/final operation roller driving channel 609 of the second/final operation roller 607. The contact between the second/final operation roller driving channel 609 and the rolled version of the seaming panel 520 in conjunction with the resulting forces compresses the combination of the seaming panel 520 and the container seaming panel 106 together. The compressed shape creates a sealed seam between the seaming panel 520 and the container seaming panel 106. The completed container assembly is referred to as a resealable container 500 and the completed seam is referred to as a container body and lid assembly seam 509, as shown in
Once sealed, the resealable container 500 is subjected to a process referred to a retort, where the contents of the resealable container 500 are heated. The heat increases an internal pressure within the resealable container 500. The increased pressure deforms the resealable container lid 510 of the resealable container 500. More specifically, because of the shape of the features of the resealable container 500, the increased pressure deforms the cap receiving socket bottom wall 534 of the resealable container lid 510 upward into a domed or bulged shape as indicated by the upward directing arrow in
In an original shape of the container lid assembly, prior to exposure to the retort process, the peripheral countersink 526 is formed having a outer peripheral countersink wall pre-retort geometry 610 on an outer, distal region and a inner peripheral countersink wall pre-retort geometry 612 on an inner, proximal region. Additionally, the cap receiving socket bottom wall 534 is referred to as a cap receiving socket bottom wall post-retort geometry 624. The outer peripheral countersink wall pre-retort geometry 610 is formed along an outer peripheral countersink wall pre-retort geometry angle delineator 611. The inner peripheral countersink wall pre-retort geometry 612 is formed along an inner peripheral countersink wall pre-retort geometry angle delineator 613. The cap receiving socket bottom wall post-retort geometry 624 is formed along a cap receiving socket bottom wall pre-retort geometry angle delineator 615. In a pre-retort condition, the outer peripheral countersink wall pre-retort geometry 610 and the inner peripheral countersink wall pre-retort geometry 612 are generally vertically oriented. Additionally, the cap receiving socket bottom wall pre-retort geometry 614 is generally planar and substantially horizontally oriented.
In a shape of the container lid assembly during the retort process, the outer peripheral countersink wall pre-retort geometry 610 is reshaped into a outer peripheral countersink wall post-retort geometry 620 on the outer, distal region and the inner peripheral countersink wall pre-retort geometry 612 is reshaped into a inner peripheral countersink wall post-retort geometry 622 on the inner, proximal region of the peripheral countersink 526. Additionally, the cap receiving socket bottom wall pre-retort geometry 614 is reshaped into a cap receiving socket bottom wall post-retort geometry 624. The outer peripheral countersink wall post-retort geometry 620 is formed along an outer peripheral countersink wall post-retort geometry angle delineator 621. The inner peripheral countersink wall post-retort geometry 622 is formed along an inner peripheral countersink wall post-retort geometry angle delineator 623. The cap receiving socket bottom wall post-retort geometry 624 is formed along a cap receiving socket bottom wall post-retort geometry angle delineator 625. During this process, the cap receiving socket bottom wall pre-retort geometry 614 transitions from a generally planar shape to a convex or bulged shape, identified as a cap receiving socket bottom wall post-retort geometry 624. This geometric condition reduces the diameter of the peripheral edge of the cap receiving socket bottom wall 534 (cap receiving socket bottom wall pre-retort geometry 614). This reduction in the diameter of the peripheral edge of the cap receiving socket bottom wall 534 draws the upper edge of the inner peripheral countersink wall pre-retort geometry 612 inward, angling the inner peripheral countersink wall pre-retort geometry 612 respectively, which is subsequently referred to as a inner peripheral countersink wall post-retort geometry 622. The reshaping of the inner peripheral countersink wall pre-retort geometry 612 to the inner peripheral countersink wall post-retort geometry 622 pulls the peripheral countersink 526 inward, impacting the lower edge of the cap receiving socket cylindrical sidewall 532. The resulting motion draws the lower edge of the outer peripheral countersink wall pre-retort geometry 610 inward, angling the outer peripheral countersink wall pre-retort geometry 610 respectively, which is subsequently referred to as an outer peripheral countersink wall post-retort geometry 620.
In a post-retort shape of the resealable container lid 510, the reshaped assembly segments 620, 622, 624 permanently retain a portion of the reshaping undergone during the retort process.
The design of the resealable container cap 660, more specifically a cylindrical sidewall inverted countersink 670 provides a flexible transition between the resealable container cap cylindrical exterior sidewall 662 and resealable container cap cylindrical interior sidewall 663, which accommodates a reshaping of the resealable container cap planar traversing surface 664 when the resealable container cap 660 is assembled onto the outer peripheral countersink wall pre-retort geometry 610. This reshaping results from a force applied to the resealable container cap planar traversing surface 664 by the cap receiving socket bottom wall 534 on the resealable container lid 510 during the retort process. A separation between the resealable container cap planar traversing surface 664 and cap receiving socket bottom wall 534 may be maintained by the off-center tamper indicator operation element 529 being in mechanical contact with the upper surface of the resealable container lid upper surface reinforcement formation 518, maintaining the relative separation between the resealable container cap planar traversing surface 664 and the cap receiving socket bottom wall 534 during the retort process in order to prevent the offset projecting incisor 668 from prematurely placing a fracturing forcing upon the cap receiving socket bottom panel circular score line 536. Additionally, the reshaping of the cap receiving socket cylindrical sidewall 532 during the retort process, more specifically, the outer peripheral countersink wall pre-retort geometry 610, impinges cam tracks 552, 554, 556 into the respective cam followers 581, 582, 583, retaining the assembly of the resealable container cap 660 onto the resealable container lid 510 during the maximum deformation during the retort process.
The design of the resealable container cap 660, more specifically, the resealable container cap cylindrical exterior sidewall 662 is adapted to accommodate the changes in shape of the peripheral countersink 526 of the resealable container lid 510 during and subsequent to the retort process. The end result enables rotational motion of the resealable container cap cylindrical exterior sidewall 662 within the peripheral countersink 526 by the consumer after completion of the retort process. This avoids any binding between the cam followers 581, 582, 583 within the peripheral countersink 526, while retaining the cam followers 581, 582, 583 against the mating surface of the respective cam tracks 551, 553, 555. It is recognized that the deformation of the cap receiving socket cylindrical sidewall 532 resulting from the retort process is adapted to enhance the engagement between the cam followers 581, 582, 583 and the mating surface of the respective cam tracks 551, 553, 555, as the deformation decreases the diameter of the lower portion of the 526.
The resulting post-retort shape is shown in a cross sectioned view of the resealable container 500, as presented in
The resealable container 500 can include features enabling nesting between assemblies 500, as shown in
Such as the resealable container cap 560 can include variations, the resealable container lid 510 is also open to variations in the design. For example, a resealable container lid 710, shown in
The cap receiving socket bottom panel circular score line 536, 736 is commonly created using a standard single step forming process. A resealable container lid 810, shown in
The multi-step process for forming a cap receiving socket bottom panel circular score line 836 is demonstrated in a series of illustrations presented in
A first score line segment punch tool 960B is similar to the lid alignment feature punch tool 960A, with the introduction of a first score line formation segment punches 933. The first score line formation segment punches 933 is divided into two segments, each segment extends between a respective first score line formation segment punch ends ready for overlap 938 and tear panel hinge formation punch area 939. The resealable container lid 810 would be seated within a subsequent lid alignment feature anvil 910A in the manufacturing process, employing the registration features 993, 997 on the lid alignment feature anvil 910A and respective registration features 894, 896 on the resealable container lid 810 to ensure accurate alignment. The first score line segment punch tool 960B would then be employed to create in at least one first score line formation segments 833 as shown in
A second score line segment punch tool 960C is similar to the lid alignment feature punch tool 960A, with the introduction of a score line fracture thinned initiation region punch 946 extending between two score line segment overlapping region punches 947. Each score line segment overlapping region punch 947 is located to align or overlap with the respective location of the first score line formation segment punch ends ready for overlap 938 of the lid alignment feature with lid bottom score line thinned formation anvil 910B. Each score line segment overlapping region punch 947 includes a second score line formation segment punch 935, which forms the actual second score segment. This creates one continuous score line 836. The resealable container lid 810 would remain seated within the lid bottom score line thinned formation anvil 910B and the second score line segment punch tool 960C would be employed to create a score line fracture thinned initiation region 846 extending between each score line segment overlapping regions 847 as shown in
The score line fracture thinned initiation region punch 946 can include a slight convex dome, as best shown in a magnified view illustrated in
In a more common embodiment, the cap receiving socket bottom panel circular score line 836 and its respective features can be formed using a single strike punch, such as a complete score line punch tool 960D working against the lid alignment feature with lid bottom score line thinned formation anvil 910B, illustrated in
A resealable container lid 1010, shown in
In use, the offset projecting incisor 568 (not shown) would travel along the incisor pathway channel 1017 approaching the score line fracture thinned initiation region 1046 within the first incisor pathway refined chamfer face 1094. The offset projecting incisor 568 then contacts and applies an opening force onto the score line fracture thinned initiation region 1046, causing the score line fracture thinned initiation region 1046 to fracture. The fracturing of the score line fracture thinned initiation region 1046 reduces the strength of the region, enabling a reduced force to fracture the score line segment overlapping region 1047 and subsequently the cap receiving socket bottom panel circular score line 1036. The lid bottom score line hinge crease 1095 directs the material about the score line fracture thinned initiation region 1046 to fold outward, introducing a clearance for free passage of the offset projecting incisor 568 to exit the end of incisor pathway channel 1017 while continuing a downward force on the incisor channel to tear panel surface transition 1092 to further propagate fracturing of the cap receiving socket bottom panel circular score line 1036. The process of separating the cap receiving socket bottom panel tear panel 1038 from the resealable container lid upper surface reinforcement formation 1018 continues as previously described in other variants, with the offset projecting incisor 568 applying a downward force to the incisor channel to tear panel surface transition 1092 in conjunction with various vertical applying force generating features engaging with one another, such as the incisor deboss panel 566 engaging with the lead in supplemental score fracture propagation and tear panel support boss 1097.
A resealable container lid 1110, shown in
All of the above configurations employ a counterclockwise rotation for fracturing the cap receiving socket bottom panel circular score line 536, 736, 836, 1036, 1136 of the respective resealable container lid 510, 710, 810, 1010, 1110. Each of these configurations are adapted to retain the respective resealable container cap 560, 660, 1160 within the cap receiving cavity of the respective resealable container lid 510, 710, 810, 1010, 1110 after the manufacturing process as well as the distribution and sales processes.
It is understood that the container lid can be modified to use a reusable or separately available version of a container cap. A resealable container lid 1210 is adapted to receive a reusable or separately available version of a container cap, such as a container lid socket engaging opening tool 1260, as shown in
The concept no longer requires the features to entrap the offset projecting incisor 568 within the incisor pathway channel 517 and just prior to the incisor channel to tear panel surface transition 592, as the container lid socket engaging opening tool 1260 is no longer pre-assembled to the resealable container lid 1210. One additional benefit of this configuration is that the container lid socket engaging opening tool 1260 can be axially symmetric, enabling assembly of the container lid socket engaging opening tool 1260 to the resealable container lid 1210 in any of three orientations. Although the exemplary embodiment mirrors the features of the container lid socket engaging opening tool 1260 in three 120 degree angular sections, it is understood that the resealable container lid 1210 and the container lid socket engaging opening tool 1260 can be design having any suitable number of like angular sections.
The container lid socket engaging opening tool 1260, detailed in
A plurality of incisors 1268 extend axially downward from a sealing surface of the opening tool planar traversing surface 1264, the incisors 1268 being equidistantly spaced and equidistant from a rotational axis of the container lid socket engaging opening tool 1260. Any of the incisors 1268 can be used for initiating a fracture of the cap receiving socket bottom panel clockwise opening circular score line 1236.
In use, the container lid socket engaging opening tool 1260 would be assembled onto the resealable container lid 1210 by aligning each opening tool formed cam follower 1281 with each inter-cam relief section 1251, 1253, 1255 and slipping each opening tool formed cam follower 1281 beneath each cam track 1252, 1254, 1256 (examples of container lid rotational and axial guide features), more specifically, engaging with the upward angled end, similar to the cam track cam follower leader section 552E previously described. The upward angled end of the respective cam track 1252, 1254, 1256 guide the respective opening tool formed cam follower 1281 into the generally horizontally arranged segment of the cam track 1252, 1254, 1256, similar to the cam track operating segment 552D. The consumer would continue to rotation the container lid socket engaging opening tool 1260 in a clockwise motion to fracture the cap receiving socket bottom panel clockwise opening circular score line 1236 at the incisor channel to tear panel surface transition 1292 and subsequently propagate the fracture of a cap receiving socket bottom panel clockwise opening circular score line 1236, while folding or bending a clockwise opening tear panel 1238 away from a resealable container lid upper surface reinforcement formation 1218 along a clockwise opening tear panel hinge 1239, as shown in
Previous variants include a seal between the cap sealing ring 565, located on a bottom surface of the resealable container cap planar traversing wall 564 of the resealable container cap 560 and a cap receiving socket bottom wall 534 of the resealable container lid 510. In another variant, the seal can be provided between features of the vertical sidewall of the resealable container cap 560 and the resealable container lid 510. This variant is employed between a resealable container lid 1310 and a resealable container cap 1360, which are described in
The resealable container lid 1310, detailed in
The resealable container lid 1310 includes a frustum shaped interior surface of a frustum shaped cap seal engaging annular surface 1340, as best shown in a section view illustrated in
The resealable container cap 1360 includes a frustum shaped exterior surface of a frustum shaped cap sealing ring surface 1367, as best shown in a section view illustrated in
When the resealable container cap 1360 and the resealable container lid 1310 are assembled to one another, the frustum shaped cap sealing ring 1365 seals against the interior surface of the frustum shaped cap seal engaging annular surface 1340, as best shown in
In the resealable container cap 1360, a concentric tamper indicator operation element 1329 on a concentric tamper indicator feature 1328 is centrally located. The concentric tamper indicator operation element 1329 is supported by an upper surface of the resealable container lid upper surface reinforcement formation 1318. The resealable container lid upper surface reinforcement formation 1318 is supported by the pressure within the sealed interior of the container. Once the seal is compromised, the pressure is released, thus eliminating any support to and from the resealable container lid upper surface reinforcement formation 1318. Without the support, the resealable container lid upper surface reinforcement formation 1318 can flex axially, thus allowing the concentric tamper indicator feature 1328 to flex accordingly and report the breach of the container.
In yet another embodiment, a resealable container lid 1410 and a respective resealable container cap 1460 are adapted to support a solid composition (i.e. food) storage and distribution container, wherein the resealable container lid 1410 is described in
It is understood that the resealable container lid 1410 can be used for smaller and larger food products, such as those mentioned above an additionally including chips, pretzels, potato sticks, larger nuts, larger spices, candies, span, thicker soups, spreadables, peanut butter, jelly, larger condiments (sauerkraut, relish), and the like.
The resealable container lid 1410, detailed in
The resealable container lid 1410 is provided with a removable sealed panel (not shown) spanning across a lower end thereof, or as a ring shaped element having a container lid dispensing aperture 1461. In a configuration where the resealable container lid 1410 includes a removable sealed panel spanning across a lower end thereof, the peripheral edge of the sealing panel can be defined by a score line. The removable seal can be opened and removed using any suitable element, such as a pull tab. The removable panel may also be of a plastic or metal foil material bonded to the lower end of the resealable container lid 1410. In a configuration excluding the removable seal bottom panel, a lower edge of the resealable container cap cylindrical exterior sidewall 1462 can be formed, introducing a peripheral bottom edge fold 1426 as a fold to reinforce the lower edge of the resealable container cap cylindrical exterior sidewall 1462 of the resealable container lid 1410 and to minimize any risk of injury.
The resealable container lid 1410 is assembled to the container cylindrical sidewall 102 using the same methods previously described. The exclusion of the cap receiving socket bottom wall 534 in the resealable container lid 1410 suggests modifications to the pneumatically operated concentric tamper indicator feature 1428. The pneumatically operated concentric tamper indicator feature 1428 excludes a tamper indicator operation element, as the resealable container lid 1410 excludes a cap receiving socket bottom wall, rendering the tamper indicator operation element as being of no use. The pneumatically operated concentric tamper indicator feature 1428 obtains support directly from pressure differential within the sealed contents section of the container.
The container lid cap can include a grip of any suitable configuration. The previous container lid caps 160, 260, 360, 460, 560, 660, 1160, 1360, 1460, each included a grip formation extending upward from a resealable container cap base element or planar traversing wall 564, 664, 1164, 1364, 1464. The container lid socket engaging opening tool 1260 includes a grip element formed on a radially exterior surface of the opening tool container overlapping sidewall 1271. A resealable container cap 1560, detailed in
Since the resealable container cap planar traversing surface 1564 extends across a highest region of the resealable container cap 1560, the resealable container cap grip element cavity 1574 can be formed as a deboss, extending inward from the top surface of the resealable container cap planar traversing surface 1564. The resealable container cap grip element cavity 1574 includes a cap grip element cavity force application surface 1575, functioning the same as the cap grip element force application surface 575 (previously described), while being a tubular interior surface thereof. An upper transition between the cap grip element cavity force application surface 1575 and the resealable container cap planar traversing surface 1564 is chamfered, creating a comfort region for the consumer during the opening and resealing processes. A depth of the resealable container cap grip element cavity 1574 would place a bottom surface of the resealable container cap grip element cavity 1574 at a desired vertical position respective to an assembly reference feature, such as the cam followers 1581, 1582, 1583 (examples of container cap rotational and axial guide features), a bottom edge of the resealable container cap cylindrical lower exterior sidewall 1562, and the like. This locates a bottom surface of a cap grip bottom wall incisor deboss panel 1566 and a depth of a respective cap grip bottom wall projecting incisor 1568 adequately to properly interact with the opening features of the resealable container lid 1310 or other respective container lid, as best shown in

A resealable container lid 2310, illustrated in
The resealable container lid 510 employs the offset projecting incisor 568 to fracture the cap receiving socket bottom panel circular score line 536, opening the resealable container lid 510. The resealable container lid 2310 utilizes a tab 2390 to fracture a cap receiving socket bottom panel circular score line 2336, opening the resealable container lid 2310.
The resealable container lid 2310 can further include a tab stabilizing boss 2396, wherein the tab stabilizing boss 2396 is formed and shaped to support the tab 2390 when initially placed in a storage or returned to the storage position. Additionally, the tab stabilizing boss 2396 alleviates any stress on the cap receiving socket bottom panel circular score line 2336 during storage and/or transit of the container.
The resealable container lid 2310 is formed having a cap receiving socket cylindrical sidewall 2332 extending substantially perpendicularly to a cap receiving socket bottom wall 2334, where the cap receiving socket cylindrical sidewall 2332 is formed having a cylindrical shape. The earn feature in the exemplary resealable container lid 2310 includes a series of socket helical threads 2352 (examples of container lid rotational and axial guide features). Each socket helical thread 2352 is formed as a linear thread, or more specifically, an uninterrupted helically shaped formation extending between a socket helical thread locking end 2352A and socket helical thread leader end 2352E. Each of the socket helical threads 2352 is formed as a boss feature extending radially inward from a surface of a cap receiving socket cylindrical sidewall 2332.
A cap receiving socket bottom panel tear panel 2338 is formed by the cap receiving socket bottom panel circular score line 2336. The cap receiving socket bottom panel circular score line 2336 is shaped into an incomplete circumference, defining a tear panel hinge 2339. The cap receiving socket bottom panel tear panel 2338 can be reinforced by any suitable reinforcement, such as a tear panel reinforcing boss 2398 formed therein. A tear panel to tear panel reinforcing boss transition 2342 provides a transition between the cap receiving socket bottom wall 2334 and the tear panel reinforcing boss 2398.
A resealable container lid upper surface reinforcement formation 2318 is formed within the cap receiving socket bottom wall 2334. A socket bottom wall to surface reinforcement formation transition 2341 provides a transition between the cap receiving socket bottom wall 2334 and the resealable container lid upper surface reinforcement formation 2318.
The resealable container lid 2310 includes a stay on tab opening system, which is detailed herein. The tab 2390 is preferably formed out of an aluminum sheet using a stamping and folding process. The tab 2390 is formed to define a stiffened peripheral edge of a body. The tab 2390 includes a tab bracket 2391 contiguously formed with the body. A tab bracket hinge 2392 provides a living hinge between the body and the tab bracket 2391. The body can be additionally reinforced by forming a tab lightening hole 2393.
The tab 2390 is assembled to a resealable container lid upper surface reinforcement formation 2318 of the resealable container lid 2310 by a rivet 2397. The rivet 2397 is formed using a stamping and forming process when forming the cap receiving socket bottom wall 2334 of the resealable container lid 2310. An aperture is formed through the tab bracket 2391. The rivet 2397 is inserted through the aperture of the tab bracket 2391, then compressed to form a button on an exposed side, as best shown in
An opening force application edge segment of the tab 2390 is located to contact the cap receiving socket bottom panel tear panel 2338 to provide an opening force to the cap receiving socket bottom panel tear panel 2338, initiating and subsequently propagating a fracture of the cap receiving socket bottom panel circular score line 2336 and applying a bending force to the cap receiving socket bottom panel tear panel 2338, causing the cap receiving socket bottom panel tear panel 2338 to bend about the tear panel hinge 2339.
In use, a consumer would lift a user force input region (a portion of the tab 2390 that is located opposite of the opening force application edge segment) of the tab 2390. A fulcrum is created between the opening force application edge segment of the tab 2390 and a contacted surface of the cap receiving socket bottom panel tear panel 2338. The load then initially generates a lifting force that is applied to the rivet 2397. During this process, the force applied by the opening force application edge segment of the tab 2390 onto the cap receiving socket bottom panel tear panel 2338 in combination with the lifting force applied to the rivet 2397 generates a shearing force between the resealable container lid upper surface reinforcement formation 2318 and the cap receiving socket bottom panel tear panel 2338, causing the cap receiving socket bottom panel circular score line 2336 to initiate a fracture. It is noted that the rivet 2397 and the opening force application edge segment of the tab 2390 are located on opposite sides of the cap receiving socket bottom panel circular score line 2336.
A finger access depression 2395 can be formed as a deboss within the resealable container lid upper surface reinforcement formation 2318 to provide a clearance for a user's finger or any other implement that would be used to apply the lifting force to the user force input region of the tab 2390. The finger access depression 2395 can be located and sized to approximately abut the distal edge of the user force input region of the tab 2390 or extend underneath the user force input region of the tab 2390.
Any suitable cap can be adapted for use with the resealable container lid 2310. The suitable cap would include a mating threaded feature formed within a sidewall of the cap. The suitable cap would not require an incisor for fracturing of the cap receiving socket bottom panel circular score line 2336 or any ramps as included in a portion of the previously described caps.
Another exemplary cap 2360, is illustrated in
The resealable container cap 2360 can be formed using any suitable forming process, including injection molding, vacuum molding, thermal forming, overmolded, transfer molded, machined, stamped, printed using additive manufacturing, turned, or any other suitable manufacturing process or combination(s) thereof. The resealable container cap 2360 can be fabricated of a plastic, a nylon, a polyvinyl chloride (PVC), Polyethylene terephthalate (PETE or PET), Thermoplastic elastomer (TPE), High-Density Polyethylene (HDPE), Polypropylene (PP), Polycarbonate, Polylactic acid (PLA), bioplasics, recycled plastics, rubber, cellulose, paper-pulp, wax impregnated paper, laminated paper, metal, aluminum alloy, steel alloy, tin, and the like and any combination thereof.
The resealable container cap 2360 includes a resealable container cap cylindrical exterior sidewall 2362 extending substantially perpendicularly to a resealable container cap planar transversing surface 2364. The resealable container cap cylindrical exterior sidewall 2362 can extend downward from a peripheral edge of the resealable container cap planar transversing surface 2364, upward from the peripheral edge of the resealable container cap planar transversing surface 2364, or the resealable container cap planar transversing surface 2364 can be centrally located along any point between a top edge and a bottom edge of the resealable container cap cylindrical exterior sidewall 2362. A series of cap helical threads 2381 (examples of a container cap rotational and axial guide features) are provided along the sidewall, where the cap helical threads 2381 are designed to rotationally engage with the mating socket helical thread 2352 of the resealable container lid 2310. In the exemplary embodiment, the cap helical threads 2381 are formed having a linear, helical shape, extending between a first end and a second end. The number of cap helical threads 2381 of the resealable container cap 2360 would be respective to the number of mating socket helical threads 2352 of the resealable container lid 2310. Each cap helical thread 2381 can be formed as a boss, as shown, or a deboss or groove (such as the cam groove surfaces 180 of the resealable container cap 160) to engage with the mating socket helical threads 2352 of the resealable container lid 2310.
A sealing feature can be incorporated into the resealable container cap 2360, wherein the sealing feature is designed to engage with a mating sealing surface of the resealable container lid 2310.

Further, the cap radial sealing ring 2367 engages with an inner wall of the peripheral countersink 2326 of the resealable container lid 2310 and is flexible in an radial direction, providing a seal between the cap radial sealing ring 2367 and the peripheral countersink 2326.
The cap axial sealing ring 2366 and the cap radial sealing ring 2367 and the balance of the resealable container cap 2360 can be formed of a same material or the cap axial sealing ring 2366 and the cap radial sealing ring 2367 can be formed of a more pliant material compared to the balance of the resealable container cap 2360 to optimize the seal.
A resealable container cap grip element base 2372 is provided as a feature to receive an opening force and a closing force that would be applied by a user. The resealable container cap grip element base 2372 can be of any suitable shape and sized respective to the resealable container cap 2360. The exemplary resealable container cap grip element base 2372 is a conically frustum shaped feature extending upward from an outer surface of the resealable container cap planar transversing surface 2364/ The resealable container cap grip element base 2372 is designed to be gripped along the resealable container cap grip element base sidewall 2371. The resealable container cap grip element base sidewall 2371 may or may not include addition features to enhance the transfer of a gripping and torsional applied force. In the exemplary illustration, a series resealable container cap grip elements 2374 are spatially arranged about the circumference of the resealable container cap grip element base sidewall 2371. It is preferred that the spacing between adjacently positioned resealable container cap grip elements 2374 are equal. Each resealable container cap grip element 2374 is shaped to include a cap grip element force application surface 2375, where each cap grip element force application surface 2375 is preferably oriented to be in a generally radial direction. Each resealable container cap grip element 2374 can include a pair of cap grip element force application surfaces 2375, where one of the cap grip element force application surfaces 2375 is to receive an opening force and the second cap grip element force application surfaces 2375 is to receive a closing force. In the exemplary illustration, the resealable container cap grip elements 2374 are a series of equally spaced axially oriented ribs that circumscribe the resealable container cap grip element base sidewall 2371.
The bottom side of the resealable container cap 2360 can be hollow, following a contour of the resealable container cap planar transversing surface 2364 and the interior of the resealable container cap grip element base 2372. The shape and dimensions of a hollowed volume within the interior side of the resealable container cap 2360 can be such to provide a clearance for the tab 2390 and any other raised features of the resealable container lid 2310.
A resealable container cap 2460, illustrated in
The resealable container cap 2460 includes a resealable container cap planar transversing surface 2464 that is a solid panel extending across an area defined by a surface of a resealable container cap cylindrical interior sidewall 2363. The resealable container cap grip element base 2472 has a tubular cylindrical shape, extending axially upward from the upper or top surface of the resealable container cap planar transversing surface 2464. The resealable container cap grip element base 2472 can include gripping features 2474 that are similar to the resealable container cap grip elements 2374 of the resealable container cap 2360 previously described.
The design of the resealable container cap 2460 is conducive to a two-part or multi-part component. The multiple parts can be assembled during an injection molding process, an injection over-molding process, using an adhesive or other bonding agent, mechanical assemble to one another, ultrasonically welded, friction weld, thermally welded or bonded, or any other suitable fabricated process or combination thereof.
The resealable container cap 2460 introduces a variation to the sealing arrangement. The resealable container cap 2460 includes a cap elastomeric sealing ring 2465 that is provided as an annular ring circumscribing an annular lower interior surface; circumscribing the interior about the resealable container cap cylindrical exterior sidewall 2462, or can completely cover a lower or interior surface of the resealable container cap planar transversing surface 2464, as best shown in
A sealing material (such as a peripheral countersink elastomer seal 2527) can be introduced within a peripheral countersink 2526 of a resealable container lid 2510, as illustrated in
The resealable container lid 2510 includes a modified layout of a cap receiving socket bottom panel circular score line 2536, where the cap receiving socket bottom panel circular score line 2536 circumscribes a peripheral edge of a cap receiving socket bottom wall 2534, enabling removal of the entire resealable container lid upper surface reinforcement formation 2518 (which functions as a tear panel for this embodiment), which is a majority of the cap receiving socket bottom wall 2534. In an opening process, the user would lift the user force input region, which would initiate a fracture of the cap receiving socket bottom panel circular score line 2536 proximate the user force input region, then the user would pull the tab 2590 using a tab lightening hole 2593 to continue to propagate the fracture of the cap receiving socket bottom panel circular score line 2536 until the entire section of the resealable container lid upper surface reinforcement formation 2518 is separated and removes from the cap receiving socket bottom wall 2534. This provides a large opening through the body of the resealable container lid 2510.
In the resealable container lid 2510, a sealing material is dispensed into the interior cavity formed by the peripheral countersink 2526, forming a peripheral countersink elastomer seal 2527, as shown in
The resealable container cap 2560 includes additional distinctions compared to the resealable container cap 2360. The resealable container cap planar transversing surface 2564 is minimally sized and provided as a small flange circumscribing the lower edge of the resealable container cap grip element base sidewall 2571 to support an offset projecting incisor 2568. The resealable container cap grip element base sidewall 2571 is located proximate a peripheral edge of the resealable container cap cylindrical exterior sidewall 2562. Essentially, an outer diameter of the resealable container cap grip element base sidewall 2571 is substantially equal to or very slightly smaller than a like diameter of the resealable container cap cylindrical exterior sidewall 2562.
The resealable container cap 2560 is of a sufficient size in both interior diameter and interior depth (when inverted) to allow for use as a container. More specifically, the resealable container cap 2560 can be sized and adapted for use as a measure cup, by including a resealable container cap measurement scale 2573, as shown in an inverted illustration of the resealable container cap 2560 presented in
Another distinction of the resealable container cap 2560 is that the resealable container cap grip element base 2572 extends above a chime of a seaming panel 2520 (alternatively referred to as a lid and container joining formation 2520) of the resealable container lid 2510. The resealable container cap grip element base 2572 of the resealable container cap 2560 is designed to provide sufficient clearance between the seaming chuck wall 2522 and the seaming chuck shoulder 2524 of the resealable container lid 2510 and the resealable container cap grip element base sidewall 2571 and resealable container cap planar transversing surface 2564 of the resealable container cap 2560 for a seaming chuck during a seaming process.
In previous embodiments, the earn features, such as cam features, helical threading, sidewall projections, sidewall grooves, and the like were formed of the same material as the respective lid and/or cap.
A resealable container lid 2610, illustrated in
The resealable container lid 2610 includes an elastomeric material that is dispensed into the peripheral countersink 2626 and continues upwards along the interior surface of the cap receiving socket cylindrical sidewall 2632 for formation of the earn feature and sealing element. In the exemplary illustration, the earn feature includes a series of helically shaped threads 2652 (examples of container lid rotational and axial guide features). The threads can be formed during the process of curing the applied elastomeric material. The elastomeric material would be dispensed in the desired region. The resealable container cap 2660 would be rotationally inserted into a cavity of the resealable container lid 2610. The rotational insertion process would drive a series of cap helical threads 2681 (examples of a container cap rotational and axial guide features) into the dispensed socket elastomeric body 2657 forming a plurality of socket helical threads 2652. The plurality of socket helical threads 2652 is set during a curing process. The assembly comprising the resealable container cap 2660 inserted into the resealable container lid 2610 can be packaged and shipped as an assembly, allowing the socket elastomeric body 2657 to cure over time. The assembly comprising the resealable container cap 2660 inserted into the resealable container lid 2610 is also designed to enable seaming of the resealable container lid 2610 to a resealable container 100.
In an alternative process, the plurality of threads 2652 can be formed using a forming tool instead of the plurality of cap helical threads 2681 of the resealable container cap 2660. The use of a forming tool enables the designer to design a formation within the socket elastomeric body 2657 that is compatible with the cap helical thread 2681 of the resealable container cap 2660, but differs in shape. For example, the socket elastomeric body 2657 can be formed as a cam 552 for use with the cam follower 581, wherein the cam follower 581 would be compatible to follow the cam 552 during use.
The socket elastomeric body 2657 provides several advantages over currently known technologies. The socket elastomeric body 2657 reduces manufacturing costs by reducing a number of forming dies and stamping steps. Additionally, the process avoids maintenance and replacement of tooling and equipment. The process can also be adapted to existing lid designs, as in a resealable container lid 2710, illustrated in
A pliancy of the socket elastomeric body 2657 can be adapted for use as a snap feature, enabling a design on the resealable container cap 2660 to snap into a receiving feature formed within the socket elastomeric body 2657 of the resealable container lid 2610. For example, the socket elastomeric body 2657 can be formed having a flange extending radially inward and the cap helical thread 2681 can be formed as a plurality of bosses, a like annular flange extending radially outward, or any other suitable feature that would overlap the radially inward extending flange of the socket elastomeric body 2657. The overlap would retain the resealable container cap 2660 and the resealable container lid 2610 assembled to one another. Engagement and a subsequent seal would be provided by the pliancy of the material used to form the socket elastomeric body 2657.
The resealable container cap 2660 is distinct from the resealable container cap 2360 in that a cap peripheral sealing edge 2367 provided on the resealable container cap 2660 is common to the cap peripheral sealing edge 2567 of the resealable container cap 2560. The cap helical threads 2681 used on the resealable container cap 2660 provides an additional function, as the cap helical threads 2681 of the resealable container cap 2660 are used to form the mating socket helical threads 2652 of the resealable container lid 2610. The socket helical threads 2652 are formed in the socket elastomeric body 2657 after the socket elastomeric body 2657 is applied to the cap receiving socket cylindrical sidewall 2632, but prior to the socket elastomeric body 2657 being cured. It is understood that the process can be reversed where the threads can be formed in the cap receiving socket cylindrical sidewall 2632 using the material of the cap receiving socket cylindrical sidewall 2632 and the elastomeric material can be applied to the resealable container cap cylindrical exterior sidewall 2662. The hard threads on the cap receiving socket cylindrical sidewall 2632 on the resealable container lid 2610 would then shape the threads in the elastomeric material applied to the resealable container cap cylindrical exterior sidewall 2662 of the resealable container cap 2660.
A resealable container cap grip element base 2672 is formed where a cap grip element force application surface 2675 is a sidewall of the resealable container cap grip element base 2672. The resealable container cap grip element base 2372 includes a circular shaped resealable container cap grip element base sidewall 2371. The circular shape requires an increased grip force or inclusion of a series a resealable container cap grip elements 2374, as illustrated to aid a user when applying a torsional force to the resealable container cap 2360. The resealable container cap grip element base 2672 is designed to enable a user to apply a normal force to the cap grip element force application surface 2675 to open the resealable container cap 2660. The cap grip element force application surface 2675 is oriented along a more radial direction, compared to the resealable container cap grip element base sidewall 2371, which would receive a tangential force. The bar shape of the resealable container cap grip element base 2672 eliminates a requirement of the resealable container cap grip elements 2374 of the resealable container cap grip element base 2372.
In summary, the resealable container cap 2660 employs three separate sealing features, including the socket elastomeric body 2657, a cap provided lid sidewall thread seal 2668, and the cap peripheral sealing edge 2367.
A resealable container lid 2710, illustrated in
The exemplary resealable container lid 2710 illustrates an ability to apply a socket elastomeric body 2757 to a currently available version of a stay on tab lid design, adapting the currently available version of a stay on tab lid design for use with any sealing cap, as previously described. This further demonstrates benefits of the concept previously taught by the resealable container lid 2610. The application of the socket elastomeric body 2757 introduces versatility for a number of options. The application of the socket elastomeric body 2757 can be provided prior to seaming of the resealable container lid 2710 to the resealable container 100, subsequent to seaming of the resealable container lid 2710 to the resealable container 100 at a filler (commonly referred to as a bottler), or by the consumer, where the elastomeric material and the resealable container cap 2760 (or any other suitable cap) could be provided as a kit.
The resealable container cap grip element 2772, 2774 of the resealable container cap 2760 includes a number of unique features. The resealable container cap grip element 2772 includes a pair of resealable container cap grip elements 2774, each resealable container cap grip element 2774 having a cap grip element force application surface 2775. The cap grip element force application surface 2775 as formed as an aperture passing through the respective resealable container cap grip element 2774. The resealable container cap grip element 2774 as formed as foldable grip, being foldable about a cap grip element hinge 2779. The cap grip element hinge 2779 is designed as a living hinge. A central portion of the resealable container cap grip element 2772, 2774 is a resealable container cap grip element base 2772, which extends between the pair of cap grip element hinges 2779 attaches the resealable container cap grip element 2772 to a resealable container cap planar transversing surface 2764. Each resealable container cap grip element 2774 freely pivots about a respective cap grip element hinge 2779 between a transport orientation (lowered) and a gripping orientation (raised).
Functionality of the resealable container cap grip element 2772, 2774 is presented in
The combination of the resealable container cap 2760 assembled to the resealable container lid 2710 introduces an ability to seam the seaming panel 2720 to the container seaming flange 106 through the resealable container cap 2760, as illustrated in
The resealable container lid 2810, illustrated in
The distinction between the resealable container lid 2810 and the resealable container lid 2310 is that the resealable container lid 2810 excludes a peripheral countersink 2326, wherein a lower edge of a cap receiving socket cylindrical sidewall 2832 is connected to a peripheral edge of a cap receiving socket bottom wall 2834 by a frustum shaped cap seal engaging annular surface 2840. In the exemplary illustration, the frustum shaped cap seal engaging annular surface 2840 is a chamfered edge or having a frustum shaped surface. It is also understood that the frustum shaped cap seal engaging annular surface 2840 can be reduced in size approaching a configuration where the lower edge of a cap receiving socket cylindrical sidewall 2832 is essentially directly connected to a peripheral edge of a cap receiving socket bottom wall 2834.
The resealable container cap 2860 differs from the resealable container cap 2360 in the design and function of the resealable container cap grip element base 2872. Initially, a resealable container cap cylindrical exterior sidewall 2862 extends upward from a peripheral edge of a resealable container cap planar transversing surface 2864, placing the resealable container cap planar transversing surface 2864 proximate to or at a bottom of the resealable container cap 2860. The resealable container cap planar transversing surface 2864 can be located at any location along an internal surface of the resealable container cap cylindrical exterior sidewall 2862, more specifically, proximate a lower edge of the resealable container cap cylindrical exterior sidewall 2862, centrally or between the lower edge of the resealable container cap cylindrical exterior sidewall 2862 and a resealable container cap grip element transition upper surface 2876. It is preferred that the resealable container cap planar transversing surface 2864 is located between the lower edge of the resealable container cap cylindrical exterior sidewall 2862 and the resealable container cap grip element transition upper surface 2876 defining a resealable container cap cylindrical interior sidewall 2863, wherein the resealable container cap cylindrical interior sidewall 2863 extends between the resealable container cap planar transversing surface 2864 and the resealable container cap grip element transition upper surface 2876.
A cap axial sealing ring 2866 can be formed about a lower edge of the resealable container cap cylindrical exterior sidewall 2862. The cap axial sealing ring 2866 is an annular flange that circumscribes the lower edge of the resealable container cap cylindrical exterior sidewall 2862. The cap axial sealing ring 2866 can be integral or unitarily fabricated with the resealable container cap cylindrical exterior sidewall 2862, as illustrated.
The cap axial sealing ring 2866 extends in a substantially axial and a generally radial direction, with a limited portion extending in the radial direction.
The illustrated resealable container cap 2860 further includes a cap radial sealing rings 2867, which extends in a substantially axially direction. The cap radial sealing rings 2867 is formed comprising a series of flexible annular ridges that can be unidirectionally arranged. Each annular ridge or angled flange defining the cap radial sealing rings 2867 extends in a substantially radial and a generally axial direction, with a limited portion extending in the axial direction.
When the resealable container cap 2860 is assembled to the resealable container lid 2810, the cap axial sealing ring 2866 engages with the frustum shaped cap seal engaging annular surface 2840 of the resealable container lid 2810 and is flexible in an radial direction, providing a seal between the cap axial sealing ring 2866 and the frustum shaped cap seal engaging annular surface 2840. The cap axial sealing ring 2866 additionally compresses or deforms in an axial direction. Further, the cap radial sealing rings 2867 engages with an inner wall of the seaming chuck wall 2822 of the resealable container lid 2810 and is flexible in an radial direction, providing a seal between the cap radial sealing rings 2867 and the seaming chuck wall 2822 (subsequently becoming a container body and lid assembly seam 2809 after the seaming panel 2820 (alternatively referred to as a lid and container joining formation 2820) is seamed to the container seaming flange 106)(
The cap axial sealing ring 2866 and the cap radial sealing rings 2867 and the balance of the resealable container cap 2860 can be formed of a same material or the cap axial sealing ring 2866 and the cap radial sealing rings 2867 can be formed of a more pliant material compared to the balance of the resealable container cap 2860 to optimize the seal.
The grip feature of the resealable container cap 2860 differs from the previously described grip features, where the resealable container cap grip element base 2872 is located radially outward of the resealable container cap cylindrical exterior sidewall 2862. The resealable container cap grip element base 2872 is cylindrically shaped having an exterior diameter that extends beyond the cap exterior sidewall 2862, defining a lower annular edge 2878. A plurality of spatially arranged resealable container cap grip elements 2874 can be provided about a resealable container cap grip element base sidewall 2871 of the resealable container cap grip element base 2872. A gap is provided between the resealable container cap grip element transition lower surface 2878 and the seaming panel 2820 to accommodate a process of seaming the seaming panel 2820 onto the container seaming flange 106. In the exemplary illustration, the resealable container cap grip element base 2872 is located and designed to remain above chime.
Applying the benefits of the resealable container cap 2760 and the resealable container lid 2710, the resealable container cap 2860 is designed where the resealable container cap 2860 can be assembled to the resealable container lid 2810 prior to and remain assembled during a process of seaming a seaming panel 2820 to the container seaming flange 106, where seaming forces are applied to the resealable container cap 2860 and transferred through the resealable container cap 2860 to the resealable container lid 2810.
The resealable container lid 2810 and the resealable container cap 2860 can be provided as a resealable lid and cap assembly height 2900. The resealable container lid 2810 and the resealable container cap 2860 can be designed to enable nesting of adjacent assemblies 2900, as illustrated in
As previously mentioned, the resealable container lid 2710, 2810 can be seamed onto the container cylindrical sidewall 102 while the resealable container cap 2760, 2860 is assembled to the resealable container lid 2710, 2810, by applying the seaming forces to the resealable container cap 2760, 2860. Details of the process are demonstrated in
The seaming process employs a seaming chuck tool 3000 in conjunction with a first operation roller 3004, then a second/final operation roller 3007, wherein the seaming chuck tool 3000 is similar to the seaming chuck tool 600, the first operation roller 3004 is similar to the first operation roller 604, and the second/final operation roller 3007 is similar to the second/final operation roller 607. Like elements or features of the seaming process 3000 are similar to the same like elements or features of the seaming process 600. Like features of the seaming chuck tool 3000 and the seaming chuck tool 600 are numbered the same except preceded by the numeral ‘30’.
The seaming chuck tool 3000 is axially seated into an interior of the resealable container cap 2860. A seaming chuck tool planar driving surface 3002 seats against resealable container cap grip element transition upper surface 2876, a seaming chuck tool upper conical driving wall 3001 seats against an interior surface of the resealable container cap grip element base sidewall 2871, and a seaming chuck tool lower conical driving wall 3003 seats against resealable container cap cylindrical interior sidewall 2863. The seaming chuck tool 3000 creates and applies an axially directed force to the resealable container cap 2860. Subsequently, the resealable container cap 2860 transfers the force and distributes the force to the resealable container lid 2810. This retains the resealable container lid 2810 in position respective to the container cylindrical sidewall 102 during the seaming process. More specifically, the chuck wall contacting cap exterior sidewall 2870 of the resealable container cap 2860 applies an axially downward and radially outward force onto the seaming chuck wall 2822 of the resealable container lid 2810, thus ensuring proper seating of the seaming panel 2820 onto the container seaming flange 106 of the container cylindrical sidewall 102. Additionally, the same transferred forces are used as an anvil when rolling the seaming panel 2820 and the respective container seaming flange 106 to create the container body and lid assembly seam 2809.
The rolling process is accomplished using a two stage roll forming operation using the first operation roller 3004, then using the second/final operation roller 3007.
The first operation roller 3004 is designed to rotate about a first operation roller rotational axis 3005. An annular cavity is defined on one edge by a first operation roller seaming chuck tool indexing surface 3020 and on an opposite edge by a first operation roller resealable container cap clearance control surface 3028. The annular cavity is concentrically shaped about the first operation roller rotational axis 3005, spanning between the first operation roller seaming chuck tool indexing surface 3020 and the first operation roller resealable container cap clearance control surface 3028. A first operation roller driving channel 3006 is a second annular recess formed in the first operation roller 3004. The first operation roller driving channel 3006 is sized and shaped to provide a first roll formation of the seaming panel 2820 and the inserted container seaming flange 106. The first operation roller driving channel 3006 is located at a predetermined distance from the first operation roller seaming chuck tool indexing surface 3020. The first operation roller seaming chuck tool indexing surface 3020 is designed to ride along a seaming chuck tool roller indexing surface 3010 of the seaming chuck tool 3000 to properly locate the first operation roller driving channel 3006. The first operation roller 3004 is rotated about the first operation roller rotational axis 3005, as the first operation roller 3004 rotationally rides about the edge of the resealable container cap 2860. As the first operation roller 3004 moves along the edge of the resealable container cap 2860, the first operation roller driving channel 3006 creates the first roll in the seaming panel 2820.
The first seam forming step using the first operation roller 3004 is repeated for a second seam forming step using the second/final operation roller 3007. The second/final operation roller 3007 is designed to rotate about a second/final operation roller rotational axis 3008. An annular cavity is defined on one edge by a second/final operation roller seaming chuck tool indexing surface 3030 and on an opposite edge by a second/final operation roller resealable container cap clearance control surface 3038. The annular cavity is concentrically shaped about the second/final operation roller rotational axis 3008, spanning between the second/final operation roller seaming chuck tool indexing surface 3030 and the second/final operation roller resealable container cap clearance control surface 3038. A second/final operation roller driving channel 3009 is a second annular recess formed in the second/final operation roller 3007. The second/final operation roller driving channel 3009 is sized and shaped to provide a second and final roll formation of the seaming panel 2820 and the inserted container seaming flange 106, creating the container body and lid assembly seam 2809. The second/final operation roller driving channel 3009 is located at a predetermined distance from the second/final operation roller seaming chuck tool indexing surface 3030. The second/final operation roller seaming chuck tool indexing surface 3030 is designed to ride along a seaming chuck tool roller indexing surface 3010 of the seaming chuck tool 3000 to properly locate the second/final operation roller driving channel 3009. The second/final operation roller 3007 is rotated about the second/final operation roller rotational axis 3008, as the second/final operation roller 3007 rotationally rides about the edge of the resealable container cap 2860. As the second/final operation roller 3007 moves along the edge of the resealable container cap 2860, the second/final operation roller driving channel 3009 creates the second and final roll in the seaming panel 2820.
Upon completion of the seaming process, the resealable container lid 2810 is permanently joined to the container cylindrical sidewall 102 (referred to as a container cylindrical sidewall 2802 in an assembled state), referenced as a resealable container 2800. A container closed bottom wall 2804 of the resealable container 2800 can be shaped and sized to be enable nesting of the container closed bottom wall 2804 into an interior of the resealable container cap 2860, as illustrated in
A majority of the various cap designs, such as the resealable container cap 2360, can be used to assist in opening a stay on tab container lid, such as the resealable container lid 2310, as illustrated in
