BACKGROUND
This disclosure relates generally to a closure for a beverage can lid having an opening, and more particularly to a closure for a beverage can lid for covering the opening.
Beverage cans for containing liquids such as carbonated beverages have become a universal and ubiquitous product. The beverage can is typically constructed of an aluminum alloy composition that may include aluminum, magnesium, manganese, silicon, and copper. The beverage can consists of a can body into which a liquid is filled and a can lid or end that is sealed to the can body. The can body may include a base or bottom that is dome shaped to resist internal pressure, a generally cylindrical section, a narrowed neck portion, and an open top edge. The can lid may include the lid portion that is about the same circumference as the narrowed neck portion of the can body, a scored line or weakened portion cut into the lid portion to form a panel or a tear panel having a hinge, a tab portion that is used to rupture the lid portion along the scored line to create an opening, a rivet that is used to secure the tab to the lid portion, and various strengthening features such as a teardrop or figure eight. The rivet is an integral piece of the lid portion and is formed by stretching the center of the lid portion upwardly and then drawn to form the rivet. The lid is sealed to the can body by trimming the open top edge of the can body, bending the trimmed edge, and seaming the bent trimmed edge to the lid. In this manner, any liquid contained within the can body is sealed. To open the beverage can the tab is lifted to press against the tear panel to partially push the tear panel into the can body to create the opening in the lid. The panel does not fully detach from the lid due to the hinge formed in the lid by ends of the score line. Once opened, liquid from inside the can body may flow through the opening.
One problem associated with the use of the beverage can is that once opened it cannot be closed again. Since the liquid within the beverage can may be carbonated, after a period of time the carbonation escapes and the liquid becomes flat or stale. Once flat, the beverage can and its contents may be discarded which may be wasteful. Also, after opening the beverage can the contents may have to be consumed quickly because the contents cannot be preserved. Further, it is also possible that the contents of the beverage can may spill due to not being able to close the opening. In particular, when an individual is walking with an opened beverage can the individual may trip or fall and the contents of the can may be spilled because the can is open. This may also be problematic if the beverage can is stationary and near electrical equipment such as a computer or a laptop and the can is accidentally knocked over. It is also possible that insects, contaminants, or other unwanted matter may infiltrate the beverage can through the opening. If this occurs, then the beverage can and its contents should be thrown away, discarded, or recycled.
Another problem associated with the use of a beverage can is a portion of the lid is not protected from becoming contaminated with dirt, dust, or other debris during manufacturing, transportation, storage, or display of the beverage can. In particular, dirt may accumulate on the lid near where the panel detaches from the lid to form the opening. If this occurs then the lid has to be cleaned to present a hygienic surface from which to drink the beverage in the beverage can. Some individuals find it unacceptable to drink from the beverage can in which the lid has been contaminated and will not purchase the beverage can.
A further problem associated with the use of a beverage can is that some individuals find it difficult to grasp the tab in order to open the beverage can. During the manufacturing process the tab is held to the lid by forming a rivet. The process of forming the rivet presses the tab directly against the lid. When this occurs the tab may be pressed against the lid making the tab difficult to grip to be able to lift up the tab.
The present disclosure is designed to obviate and overcome many of the disadvantages and shortcomings experienced with prior beverage can constructions. Particularly, it would be advantageous to be able to have a closure for a beverage can lid for preserving the contents of the beverage can. Moreover, the present disclosure is related to a closure for a beverage can lid that can be used to reseal the beverage can for later use, to prevent spillage, or to prevent contaminants from entering the can once opened. It would also be advantageous to have a closure for a beverage can for preventing contaminants from accumulating near the tear panel. Further, it would be advantageous to have a closure for a beverage can that lifts the tab to provide for easier grasping of the tab to open the beverage can.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
Referring now to the drawings, wherein like numbers refer to like items, number 10 identifies a preferred embodiment of a closure for a beverage can lid constructed according to the present disclosure. Referring now to FIGS. 1 and 2, the closure 10 is shown to comprise a body 12 having a back end 14 and a front end 16. The back end 14 has a track portion 18 that is used to ride, slide, or move along a rim (not shown) of a beverage can lid (not shown). The front end 16 has a first or left tooth or ear section 20 having a left front edge 22, a central rounded recess or slot 24, and a second or right tooth or ear section 26 having a right front edge 28. The first section 20 has a left nub or rib portion 30 at the left front edge 22 and the second portion 26 has a right nub or rib portion 32 at the right front edge 28. The rib portions 30 and 32 are shorter than the central rounded recess 24. Although the rib portions 30 and 32 are shown it is possible that the closure 10 may not require the rib portions 30 and 32. The body 12 also has a front panel portion 34, a rear panel portion 36, and a step down section 38 between the front panel portion 34 and the rear panel portion 36, a left edge 40, and a right edge 42. The step down section 38 is curved or arcuate in shape and spans from the left front edge 22 to the right front edge 28. The track portion 18 is also curved or arcuate in shape and is adapted to fit around a rim (not shown), as will be described in further detail herein.
FIG. 3 shows a side perspective of the closure for a beverage can lid 10 constructed according to the present disclosure. The closure 10 has the body 12 having a top surface 44 and a bottom surface 46. The bottom surface 46 is adapted to engage with or cover a beverage can lid (not shown). The track portion 18 has a lower lip portion 48 and a generally inverted U-shaped portion 50. The U-shaped portion 50 continues to an arched segment 52 and a generally U-shaped portion 54. The generally U-shaped portion 54 continues to an angled segment 56 and to the rear panel portion 36. The track portion 18, the arched segment 52, and the generally U-shaped portion 54 have a bottom surface 58 that is adapted to engage with or cover a rim (not shown) of a beverage can (not shown). The closure 10 is of unitary construction in that the body 12, the track portion 18, the arched segment 52, the generally U-shaped portion 54, and the angled segment 56 are formed from one piece of material.
With reference now to FIGS. 4 and 5, the closure 10 is illustrated being positioned on a rim 70 of a beverage can lid 72. The beverage can lid 72 has a tab 74 that is staked to a rivet 76. A score line 78 is formed in the beverage can lid 72 which defines a tear panel 80. The tear panel 80 is adapted to be partially detached from the beverage can lid 72 and is held to the beverage can lid 72 by use of a hinge 82. The beverage can lid 72 also has an indented area 84 with such indented area 84 being in the shape of a teardrop or a figure eight. In operation, the tab 74 is lifted to press into the tear panel 80 to open the beverage can lid 72 by rupturing the tear panel 80 along the score line 78. Once opened, the contents of a beverage can (not shown) may be removed through an opening (not shown) formed by partially detaching the tear panel 80. The closure 10 is shown being in an initial position in which the beverage can lid 72 is not opened and the closure 10 is not covering the tear panel 80. Although the initial position is depicted in FIGS. 4 and 5 as being at the 12 o'clock position it is possible and contemplated that the initial position may be at any location around the rim 70. In the initial position the closure 10 is not preventing the tab 74 from being lifted or used. The closure 10 is positioned on the rim 70 and is capable of moving or sliding along the rim 70 to move the closure 10 from the initial position. The body 12 of the closure 10 is positioned below the tab 74 with the left ear section 20 and the right ear section 26 being underneath the tab 74. Although hidden in these particular views, the central rounded recess 24 fits around the rivet 76. The rim 70 also has a surface 86 against which the bottom surface 58 (FIG. 3) of the closure 10 slides upon during use. As can be appreciated, the shape of the track portion 18 (FIGS. 1, 2, and 3) is similar to the shape of the rim 70 and the shape of the U-shaped portion 50, the arched segment 52, and the generally U-shaped portion 54 are similar to the shape of the surface 86. This allows the closure 10 to easily slide along the rim 70.
FIGS. 6 and 7 depict the beverage can lid 72 being opened and the closure 10 being in the initial position. In this configuration, the tab 74 has been used to rupture or detach the tear panel 80 to form an opening 88 in the beverage can lid 72. The closure 10 has not interfered with the operation of the tab 74. The tear panel 80 is held to the beverage can lid 72 by use of the hinge 82. In this manner, the tear panel 80 will not fall into a beverage can (not shown) attached to the beverage can lid 72. The closure 10 is positioned on the rim 70 and is capable of moving or sliding along the rim 70 to move the closure 10 from the initial position. The body 12 of the closure 10 is positioned below the tab 74 with the left ear section 20 and the right ear section 26 being underneath the tab 74.
Referring now to FIGS. 8 and 9, the closure 10 is shown in a closed position covering either the tear panel 80 (FIGS. 4 and 5) when the beverage can lid 72 (FIGS. 4 and 5) has not been opened or the opening 88 (FIGS. 6 and 7) when the beverage can lid 72 (FIGS. 6 and 7) has been opened. The closure 10 has been moved or rotated about the rivet 76 by use of the central rounded recess 24 (FIGS. 1 and 2) from the initial position to the closed position by sliding or moving the track portion 18 along the rim 70. The body 12 completely covers the tear panel 80 or the opening 88 and is below or beneath the tab 74. The step down section 38 also rides within the indented area 84 which ensures that the body 12 remains flat or tight against the beverage can lid 72. Due to the left tooth section 20 the hinge 82 (FIGS. 4, 5, 6, and 7) is also covered to prevent any leaking of fluid from the beverage can (not shown) when the closure 10 is in the closed position. The rib portions 30 and 32 are also used to hold the tab 74 in place. The rib portions 30 and 32 are further used to move the tab 74 so that the cover 10 can freely rotate or slide. As has been described above, the shape of the track portion 18 (FIGS. 1, 2, and 3) is similar to the shape of the rim 70 and the shape of the U-shaped portion 50, the arched segment 52, and the generally U-shaped portion 54, all of which are shown in FIG. 3, are formed to be similar to the shape of the surface 86. This allows the closure 10 to easily slide or ride along the rim 70.
The operation of the closure 10 may be as follows with reference to FIGS. 1-9. A beverage can body is filled with a beverage and the beverage can lid 72 is sealed to the beverage can body to form the rim 70 by a seaming operation to construct a beverage can. Once the beverage can is manufactured the closure 10 may be positioned on the rim 70 of the beverage can by inserting the front end 16 underneath the tab 74 and placing the track portion 18 over the rim 72. The closure 10 is then moved to the initial position. The tab 74 is lifted to rupture the tear panel 80 along the score line 78. The tear panel 80 is partially detached or separated from the beverage can lid 72 to form the opening 88 and any beverage inside the beverage can may be removed through the opening 88. When an individual wants to cover or seal the opening 88 the closure 10 is moved from the initial position to the closed position to fully cover the opening 88. When the individual wants to again drink from the beverage can the closure may be moved from the closed position to the initial position. The beverage can may be held, stored, or refrigerated without concern that the beverage will spill out of the beverage can or that the beverage will become stale or that the beverage will be contaminated. As is known, once the beverage from the beverage can has been consumed, the beverage can and the closure 10 may be recycled.

The track portion 308 also has the second or right lower lip portion 344 and the second or right generally inverted U-shaped track portion 346. The track portion 308 has the finger grab portion 348 positioned between the first generally U-shaped track portion 338 and the second generally inverted U-shaped track portion 346. The surface 350 is also shown. The body 302 also has the outer arcuate section 352 formed between the track portion 308 and the first central section 328 and the second central section 332. The second central section 332 has the front section 354, the rear section 356, and the line 358 that illustrates the transition from the higher front section 354 to the lower rear section 356.
FIG. 19 illustrates the closure 300 being positioned on a rim 400 of a beverage can lid 402. The beverage can lid 402 has a tab 404 that is staked to a rivet 406. The beverage can lid 402 also has an indented area 408 with such indented area 408 being in the shape of a teardrop or a figure eight. The closure 300 is depicted in an initial orientation at the 6 o'clock position 410. The track portion 308 is snapped or secured in place to the rim 400. The track portion 308 facilitates movement of the closure 300 around the rim 400. Although not depicted in this particular view, it should be appreciated that the central rounded recess or slot 326 is configured to rotate about the rivet 406. The slot 326 has a larger circumference than the rivet 406 to allow the closure 300 to rotate about the rivet 406 without contacting the rivet 406. The first central section 328 having the first step down section 330 are also designed to fit within the indented area 408. This particular configuration assists in allowing the closure 300 to rotate adjacent to the lid 402 while keeping the closure 300 close to the lid 402 and the indented area 408.
With particular reference now to FIG. 20, the closure 300 is illustrated being moved or rotated to a 9 o'clock position 412. The lid 402 has the rim 400, the tab 404, the rivet 406, and the indented area 408. With the closure 300 moved to the 9 o'clock position 412 the lid 402 is shown to also include a tear panel 414 that is adapted to be ruptured along a score line 416. The first central section 328 having the first step down section 330 is also shown fitting within the indented area 408 and being able to rotate within the indented area 408. As can be appreciated, the finger grab portion 348 may be used to grasp the closure 300 to rotate the closure 300 about the rim 400.
FIG. 21 shows the closure 300 being positioned at a 12 o'clock position 418 on the rim 400 of the beverage can lid 402. The tab 404 is shown being lifted due to the configuration of the front section 354 of the second central section 332 being higher than the rear section 356. In essence, the front section 354 lifts the tab 404 up and with the rear section 356 being lower than the front section 354 this provides the ability to place a finger underneath the tab 404 to easily grasp the tab 404 to lift the tab 404 up to open the lid 402. The tab 404 is further lifted to press against the tear panel 414 to rupture the tear panel 414 along the score line 416 to open the lid 402. Again, having the front section 354 higher than the rear section 356 props the tab 404 up and away from the lid 402 to easily open the lid 402. The second central section 332 also serves to center or align the tab 404 in place to be able to easily open the lid 402. The first central section 328 having the first step down section 330 is also shown fitting within the indented area 408 and being able to rotate within the indented area 408. The finger grab portion 348 may be used to grasp the closure 300 to rotate the closure 300 about the rim 400 to the 12 o'clock position 418.
In operation, the closure 300 is placed on the rim 400 of the beverage can lid 402. Although not shown, the beverage can lid 402 is sealed to a beverage can containing a beverage. The closure 300 is initially positioned in the 6 o'clock position 410, as is shown in FIG. 19. In this position 410 the cover 300 protects the tear panel 414 from accidentally opening during transportation or storage. This also aids in keeping the tear panel 414 of the lid 402 clean from debris. Once the lid 402 needs to be opened the closure 300 is rotated about the rim 400 to the 12 o'clock position 418. In the 12 o'clock position 418 the cover 300 completely uncovers the tear panel 414 and the tab 404 is easy to grasp. The tab 404 is lifted to press into the tear panel 414 to open the beverage can lid 402 by rupturing the tear panel 414 along the score line 416. Once opened, the contents of a beverage can (not shown) may be removed through an opening (not shown) formed by partially detaching the tear panel 414. In the 12 o'clock position 418 the closure 300 does not prevent the tab 404 from being lifted or employed. Since the closure 300 is positioned on the rim 400 the closure 300 is capable of moving or sliding along the rim 400 to move the closure 300 back to the 6 o'clock position 410. Once in the position 410, the closure 300 is used to cover the opening formed in the lid 402. The closure 300 prevents any beverage or liquid within the beverage can from leaking out. The first tooth or ear section 310 and the second tooth or ear section 318 assists in preventing any leaking of the beverage from the beverage can. As should be appreciated, the shape of the track portion 308 is similar to the shape of the rim 400. This allows the closure 300 to easily slide along the rim 400 reducing or eliminating any rotational friction.
Preferably, the closures for a beverage can lid 10, 100, 200, and 300 will be constructed of a relatively lightweight material so that it can be easily used and manufactured. By way of example only, the closures 10, 100, 200, and 300 may be constructed of aluminum or an aluminum alloy. Further, the closures for a beverage can lid 10, 100, 200, and 300 may have a thickness with such thickness being less that the thickness of a beverage can lid. This may lead to the closures for a beverage can lid 10, 100, 200, and 300 costing less than the beverage can lid to manufacture.
Although it has been indicated herein that the closures for a beverage can lid 10, 100, 200, and 300 are used with cans that contain a liquid, such as a carbonated beverage, it is also possible and contemplated that the cans may contain other items such as non-carbonated beverages, powders, spices, foods, syrups, gums, candies, or any other item that can be removed from an opening in the lids and may need to be resealed or closed.
From all that has been said, it will be clear that there has thus been shown and described herein a closure for a beverage can lid which fulfills the various objects and advantages sought therefor. It will be apparent to those skilled in the art, however, that many changes, modifications, variations, and other uses and applications of the subject closure for a beverage can lid are possible and contemplated. All changes, modifications, variations, and other uses and applications which do not depart from the spirit and scope of the disclosure are deemed to be covered by the disclosure, which is limited only by the claims which follow.
