DETAILED DESCRIPTION

As described herein, a three-piece pocket-size hybrid container has an inner ring secured to the inside of an outer base housing and a cover to snugly close over the inner ring.

In an embodiment, the cover and outer base housing are of one material and the inner ring is of a second material. In a preferred embodiment, the cover and outer base housing are metal and the inner ring is plastic, the inner ring providing a mechanical connection with the base and a friction fit with the cover such that the cover and base are supported only by the inner ring. The hybrid container preferably contains consumer items within an interior volume defined by the space within the inner ring.

Preferably, the hybrid container outer base housing and cover are shaped with all edges rounded with a smooth radius. This gives an appealing feel to the hybrid container when handled or placed in a pocket. More preferably, the hybrid container is cylindrical with a round cover and round outer base housing, although in other embodiments the hybrid container may have other shapes such as cuboid.

Preferably, the outer base housing fits securely around the inner ring. Preferably, the sidewall of the cover surrounds the inner ring to form a snug closure over the inner ring. The cover sidewall may extend downward to meet the sidewall of the outer base housing such that the hybrid container has a solid flush sidewall when closed. In other preferred embodiments the cover sidewall extends downward toward the sidewall of the outer base housing such that an annular gap extends around the periphery of the hybrid container between the cover sidewall and the outer base housing sidewall when the hybrid container is closed.

In a preferred embodiment, the outside of the hybrid container cover and/or outer base housing will be pre-printed and treated with a protective scratch resistant textured material such as a polymer coating. Preferably, the inside of the hybrid container cover and outer base housing will be treated with a corrosion-resistant coating such as an epoxy coating for corrosion protection. The cover and/or the outer base housing may have a top and bottom recessed panel. Such a recessed panel is preferred to allow for embossing, labeling, ink jet printing, onserting, and other similar applications.

In a preferred embodiment, the edge of the cover sidewall is rolled inwardly. The rolled edge engages the outer surface of the inner ring to provide a friction fit around the inner ring. Preferably, the top of the inner ring is tapered to allow easy positioning or alignment of the cover rolled edge around the top of the inner ring and to make a snug closure of the hybrid container when the cover and base are squeezed towards each other. The inner ring preferably contacts the bottom of the base and the top of the cover when the cover is closed.

In a preferred embodiment, the hybrid container has a 42/58% split ratio of cover height to outer base housing height. That is, the cover overlies about 42% of the height of the inner ring and the base overlies about 58% of the inner ring. The parting line between the cover and the outer base housing is thus located such that 42% of the hybrid container height may be partitioned to the cover and 58% of the hybrid container height may be partitioned to the outer base housing. Such a preferred split ratio is proportioned to indicate to a user an upright position during cover removal with the thinner cover (lid) being oriented above the base. However, the split ratio can have any other desired value. For example, the hybrid container may have a split ratio in a range of 70% to 30% of the container height partitioned to the cover height and correspondingly 30% to 70% partitioned to the outer base housing height. In an embodiment, the split ratio can also be selected to achieve a certain desired internal volume consistent with the amount of product to be stored in the hybrid container. For example, the hybrid container can be 25 mm high and have a 68 mm diameter. In such an embodiment, the cover height can be 10.5 mm and the outer base housing height can be 14.5 mm.

In an embodiment, the inner ring is a single piece of injection molded plastic such as low density polyethylene resin. Suitable plastics include, without limitation, polypropylene, polyethylene, polystyrene, nylon, polysulfone, polyester, polyurethane, and combinations thereof. Because some plastics absorb flavors, the preferred plastic is polypropylene if the enclosed product includes flavors.

In one embodiment, the cover and outer base housing are formed of a metal stamping. Suitable metals, include without limitation aluminum, aluminum alloys, steels, stainless steel alloys, titanium, titanium alloys, magnesium, magnesium alloys, tin, tin alloys, copper, copper alloys, brasses, and combinations thereof. The cover and base are preferably identical in shape with the only differences being the height of the sidewall and width of the inwardly rolled edge.

Preferably, the inner ring provides a seal to the hybrid container cover. Also preferably, the inner ring facilitates removing the cover and replacing the cover to open and close the hybrid container. In a preferred embodiment the seal is not hermetic, but is optimized such that the product is allowed to off-gas and yet retain freshness. In a preferred embodiment, the inner ring has one or more channels, vents and/or ribs to allow egress of gas and to facilitate easier opening and closing of the hybrid container.

In an embodiment, the inner ring has a snap ring around the outer periphery such that when opening and closing the hybrid container the cover sidewall elastically expands and/or the inner ring elastically contracts to pass a protrusion of the cover sidewall over the snap ring. The protrusion may be, for example, an inwardly rolled edge of the cover sidewall or annular projection forming another snap ring on the interior of the cover sidewall.

In the preferred embodiment, the inner ring is mechanically secured to the outer base housing. Preferably, the inner ring is secured to the outer base housing by a machine curl on the base as described later with reference to FIGS. 3B and 4B. Also, preferably, no adhesives or glues are used to aid in securing the inner ring to the outer base housing, but such adhesives may be used if desired. Preferably, the inner ring is secured such that the bottom of the inner ring makes a tight seal against the bottom of the outer base housing.

The inner ring preferably includes a tapered bottom wall with an annular step located approximately midway between the top and bottom of the inner ring. The preferred location of the annular step may be selected so that the hybrid container has a split ratio of cover height to outer base housing height in the range of 70:30 to 30:70. Preferably, the location of the annular step may be selected so that the split ratio of cover height to outer base housing height is 42:58. Such an arrangement allows the inner ring to be snap fitted in the base with the bottom of the ring contacting the bottom panel of the base, the sidewall of the base contacting the tapered wall and the step contacting the machine curl of the base sidewall.

While the inner ring is preferably secured to the outer base housing by a machine curl, other mechanical joints can be used. For example, an embodiment may include dimpling the outer base housing to clamp the inner ring securely to the outer base housing. Right-handed or left-handed threads may also be used to screw the inner ring into the outer base housing or a combination of machine curling, dimpling, and/or threads may be used.

While a friction fit is preferably used to hold the cover to the inner ring, the cover may be held by other arrangements. For example, the inner ring may be threaded on the exterior surface of the upper portion surrounded by the cover. The interior surface of the cover sidewall may have matching threads such that rotation of the cover relative to the outer base housing opens the container and rotation in an opposite direction closes the cover while the inner ring is clamped within the base to prevent the inner ring from turning.

In an embodiment, a membrane seal (FIG. 7A) surrounds the periphery of the hybrid container. The membrane overlaps the parting line seam between the cover and the outer base housing. Preferably, the membrane seal is a pressure sensitive clear label applied to the surface of the container sidewall. Also preferably, the membrane seal may be used as a tamper evident seal. Also preferably, the membrane material may be polypropylene. While the membrane seal is preferably polypropylene, the membrane seal may be other suitable materials such as heat shrinkable polyolefin film.

In a preferred embodiment, the membrane seal is perforated to allow for appropriate hybrid container breathe-ability. Also preferably, the membrane seal covers the circumference of the hybrid container and is positioned to center such perforations across the parting line of the cover and outer base housing or gap between the spaced apart cover and outer base housing when the hybrid container is closed. The use of perforated membranes improves the ability to open the hybrid container. In use, the consumer breaks the seal at the perforation prior to opening the hybrid container. In another embodiment, the membrane seal includes a pull tab that is engaged to break the seal of the membrane and provide access to the contents of the hybrid container.

The three-piece pocket-size hybrid container has an inner ring secured to the inside of an outer base housing and a cover to snugly close over a protruding portion of the inner ring. As illustrated in FIG. 1A, a cover 100 (shown in an inverted position) consists of a top portion 106 to cover an interior volume of the hybrid container, a flange portion 110 which engages the inner ring, and a lip portion 104 which engages an upper edge of the outer base housing or is spaced apart from the upper edge of the outer base housing. The cover top portion 106 joins the flange portion 110 in a rounded corner 108 having a smooth radius. Although the top portion 106 is shown as circular in the preferred embodiment, other embodiments may have other shapes such as square. In such an alternate embodiment, the flange portion 110 would have four sidewalls (not shown) joined to each other and to the top portion 106 with rounded corners.

FIG. 1B shows a plan view of the hybrid container cover 100 and FIG. 1C shows a cross section of the cover 100 sectioned along A-A in FIG. 1B. The cover 100 has a recessed top panel 112 to accept a label (not shown). The interior of the cover flange portion 110 fits snugly around the protruding portion of the inner ring to close the hybrid container. Preferably, a lip of the cover flange 110 is rolled inward and the rolled edge 102 engages the inner ring to snugly close the hybrid container.

The inner ring 200 of the hybrid container 100 is shown in FIG. 2A. The inner ring 200 has an interior surface 202, an upper lip 204, a protruding portion 210, a step 206 in an exterior surface of the inner ring 200 to make a mechanical joint with the outer base housing, a lower portion 212 which fits snugly within the outer base housing, and the lower portion including a rounded edge 208. Although the step 206 is shown as extending around the periphery of the inner ring 200, this is not required in all embodiments, for example, the step 206 could be one or more discrete depressions or recesses in the lower portion 212 to accept mating projections on the outer base housing or vice versa. In a preferred embodiment, the lower portion 212 is tapered to provide a smaller outer diameter at its bottom edge and facilitate insertion of the inner ring in the base to lock the upper edge of the base over the step 206.

FIG. 2B and FIG. 2C illustrate a cross-section and plan view of the inner ring 200, respectively. The inner ring 200 may have at least one vertically extending channel 216 to allow egress of gas to and/or from the interior of the hybrid container to maintain freshness of the product contained therein and to facilitate easier opening and closing of the hybrid container when in use. Air flows through the vertically extending channels 216 past the rolled edge 102 of the cover 100 into an interior space of the hybrid container when the cover 100 is lifted away from the outer base housing. Conversely, air flows out of the interior space of the hybrid container through the vertically extending channels 216 past the rolled edge of the cover 102 when the cover is pressed down on the inner ring protruding portion 210 toward the outer base housing to close the hybrid container.

The vertically extending channels 216 may extend partially up the protruding portion 210 as shown in FIG. 2B or all the way to the upper lip 204. The vertically extending channels 216 may vary in width to adjust the amount of air flow past the rolled edge 102. In other embodiments the channel 216 may be replaced or combined with any suitable air passage arrangement such as grooves, vents and/or ribs. In a preferred embodiment, the inner ring 200 has three channels 216 distributed evenly around the circumference of the protruding portion 210.

The upper lip 204 of the inner ring 200 may be tapered to facilitate alignment and placement of the cover 100 over the inner ring 200. The taper angle is not limited and may be adjusted such that a gradual increase in pressure is required as the cover 100 approaches a closed position.

Although the inner ring 200 is shown as circular in the preferred embodiment, other embodiments may have other shapes such as substantially square. In such an alternate embodiment, the inner ring 200 would have four sidewalls (not shown) joined to each other with rounded corners to fit snugly within an outer base housing having the same shape.

FIG. 3A shows the outer base housing 300 of the pocket-size hybrid container. The outer base housing 300 has a bottom portion 306 of a size and shape to substantially match the top portion 106, a sidewall portion 310 joined to the bottom portion 306 in a rounded corner 308 with a smooth radius, and a sidewall upper lip 314. FIG. 3B shows a cross-section of the outer base housing 300 having a recessed panel 312 and the sidewall upper lip 314 curled to form a ridge portion 316 that protrudes toward the interior of the outer base housing 302. The ridge portion 316 protrudes above the step 206 of the inner ring 200 to securely attach the inner ring 200 to the outer base housing 300.

Although the bottom portion 306 is shown as circular in the preferred embodiment, other embodiments may have other shapes such as square. In such an alternate embodiment, the sidewall portion 310 would have four sidewalls (not shown) joined to each other and to the bottom portion 306 with rounded corners.

FIG. 4A illustrates the inner ring 200 secured within the outer base housing 300. A cross-section of the inner ring 200 secured within the outer base housing 300 is shown in FIG. 4B. The outer base housing 300 sidewall portion 310 snugly surrounds the lower portion 212 of the inner ring 200. The ridge portion 316 protrudes over the step 206 to clamp the inner ring to the outer base housing. FIG. 4B shows the bottom of the inner ring 214 is tightly sealed against the bottom of the outer housing 306. The inner ring protruding portion 210 extends above an upper rim 304 of the outer base housing 300. The inner volume of the container is defined between the inner surface of the inner ring, the bottom panel of the base and top panel of the cover, the inner ring providing a mechanical joint with the base and friction fit with the cover.

FIG. 5 illustrates the pocket-size hybrid container 400 having the cover 100 closed over the outer base housing 300. The lip portion 104 of the cover 100 proximately meets the upper rim 304 of the outer base housing 300 forming the container parting line 404. The sidewall portion 310 and the flange portion 110 form a solid flush container sidewall. The container parting line 404 can be as shown or higher or lower on the container sidewall.

FIG. 6A shows a cross-section view of the pocket-size hybrid container 400 having the cover 100 closed over the outer base housing 300. As seen in FIG. 6A, the rolled edge 102 of flange portion 110 snugly surrounds the protruding portion 210 of the inner ring 200. The lower portion 212 fits snugly within the outer base housing 300, secured by the ridge portion 316 fitted over the step 206. The cover lip portion 104 engages the upper rim 304 of the outer base housing 300. Thus, an interior volume 402 is defined between the cover 100, the interior surface 202 and the bottom portion 306. In an embodiment, the interior volume 402 contains consumer products. Preferably, the product is moist smokeless tobacco (MST).

FIG. 6B shows another embodiment of the pocket-size hybrid container 400 having the cover 100 closed over the outer base housing 300. As seen in FIG. 6B, the cover flange portion rolled edge 102 snugly surrounds the inner ring protruding portion 210. The inner ring lower portion 212 is locked within the outer base housing 300, secured by the ridge portion 316 fitted over the step 206. In the closed position, the cover lip portion 104 is spaced apart from the upper rim 304 such that a gap 406 extends around the circumference of the hybrid container 400 between the cover and the outer base housing.

FIG. 6B shows an optional annular ridge 218 on the external surface of the protruding portion 210. The ridge 218 acts as a snap ring to latch the cover closed. The cover sidewall 110 moves elastically outward and/or the inner ring moves elastically inward to pass the rolled edge 102 slidably over the ridge 218 to open and close the hybrid container 400. The annular ridge 218 engages the rolled edge 102 to securely close the hybrid container 400. The position of the ridge 218 is not particularly limited and can be as shown in FIG. 6B or higher or lower. The position of the snap ring may depend on the height of the cover flange 110. The snap ring may be a continuous or discontinuous ridge. The snap ring can be in an embodiment with or without the gap 406. The gap 406 can be in an embodiment of the hybrid container 400 with or without the snap ring ridge 218.

FIG. 7A shows a membrane seal 500 surrounding the periphery of the hybrid container 400. The membrane seal 500 overlaps the parting line 404 seam between the hybrid container cover 100 and the hybrid container outer base housing 300. In an embodiment, the membrane seal 500 is a pressure sensitive clear label. Preferably, the membrane seal 500 may be used as a tamper evident seal. Also preferably, the membrane material is polypropylene. However, the membrane seal may be other suitable materials such as heat shrinkable polyolefin film.

As seen in FIG. 7A, the membrane seal 500 may be perforated 504 according to a preferred embodiment to allow for hybrid container breathe-ability. Also shown in FIG. 7A, the membrane seal 500 covers the circumference of the hybrid container 400 (FIG. 5) and may be positioned to center such perforations 504 across the parting line 404 of the cover 100 and outer base housing 300 or the gap 406 between the cover 100 and outer base housing when the hybrid container 400 is closed. The parting line 404 position and the gap 406 position can be as shown by perforations 504, or higher or lower. Likewise, the perforations 504 can be as shown or higher or lower.

FIGS. 7B-7F show embodiments of the membrane seal 500 prior to placement around the periphery of the hybrid container 400. As shown in FIG. 7B, the membrane seal 500 has a first terminal end 506 and second terminal end 508 which can overlap, meet at a vertical seam or be separated by a gap when the membrane seal 500 is attached to the container sidewall.

The membrane seal 500 preferably has a plurality of horizontal sections separated by perforations 504. For example, an upper section 510 separated from a mid section 512 by a first row of perforations 518, and a lower section 514 separated from the mid section 512 by a second row of perforations 520. Preferably, inner surfaces of upper and lower sections 510, 514 are bonded to the cover sidewall 110 and base sidewall 310, respectively, such that the container can be opened after the mid section 512 is removed by breaking perforations 518, 520. In such an embodiment the mid section 512 is known as a tear-off strip of a tamper evident seal. Preferably, the inner surfaces of upper and lower sections 510, 514 are bonded to the cover sidewall 110 and base sidewall 310 by a pressure sensitive adhesive.

While the inner surfaces of upper and lower sections 510, 514 are preferably bonded to the cover sidewall 110 and base sidewall 310, the upper and lower sections 510, 514 may also be not bonded such that the membrane seal 500 may optionally be completely removed when the tear-off strip 512 is severed. For example, the membrane seal 500 can be shrink fit to the periphery of the container 400 optionally covering the sidewall, the sidewall and portions of the top and/or bottom, or the entire container. In such an embodiment, the membrane 500 may be completely removed from the container 400 after the tear-off strip 512 is removed.

Preferably, the widths of the upper and lower sections 510, 514 are the same and the width of the mid section 512 is the same, wider or narrower than the upper and lower sections 510, 514. FIG. 7B shows the mid section 512 narrower than the upper and lower sections 510, 514 and FIG. 7C shows the mid section 512 approximately the same width as the upper and lower sections 510, 514. Although not required, the upper and lower sections 510, 514 may overlap the corners of the container 108, 308. The terminal ends of the horizontal sections 510, 512, 514 may be flush or rounded to facilitate attaching the membrane seal 500 to the container and locating, lifting and/or gripping the tear-off strip to open the container.

FIG. 7D shows a preferred embodiment where the terminal ends 524, 526 of the mid section 512 extend beyond the terminal ends of the upper and lower sections 510, 514. Preferably, the mid section terminal ends 524, 526 are rounded and can be pull tabs for tearing off the mid section 512. Also preferably, the mid section 512 is wider than the upper and lower sections 510, 514.

FIG. 7E shows an embodiment where a perforation 532, divides the mid section 512 into two mid sections 528, 530. In such an embodiment, mid sections 528, 530 can be removed simultaneously or consecutively. That is, pulling on a first terminal end of the upper mid section 528 initially removes the upper mid section 528 around the circumference of the container 400. A second terminal end of the upper mid section 528 being connected to a terminal end of the lower mid section 530 removes the lower mid section 530 from the periphery of the container 400 leaving the upper and lower sections 510, 514 attached to the cover and base allowing the container to be opened.

FIG. 7F shows an embodiment where the terminal ends 506, 508 of the membrane seal 500 are flush. The mid section 512 between rows of perforations 518 and 520 is shown narrower than the upper and lower sections 510, 514.

Although not limited, the membrane seal 500 may be 10-15 mm wide. Preferably 12 mm wide. The upper and lower sections 510, 514 may each be 2-7 mm wide and the mid section 512 width may be 1-8 mm wide. Preferably, the mid section 512 is 6 mm wide and the upper and lower sections 510, 514 are each 3 mm wide.

In an embodiment, the pocket-size hybrid container 400 is about 30 mm to about 100 mm in diameter, and about 15 mm to about 40 mm in height. In a preferred embodiment, the hybrid container 400 fits in the palm of an adult user's hand or in a pocket. Most preferably, the size of the interior volume 402 is determined based on the amount of product to be enclosed.

Assembly of a hybrid container is very simple. The inner ring is inserted into the outer base housing 300 and pressed down until the upper lip 314 of the outer base housing 300 is snapped over the step of the inner ring 206. The cover 100 can be installed on the protruding portion 210 of the inner ring 200.

In use, a consumer grips the underside of the hybrid container 400 in the palm of his/her hand, while lifting the cover 100 away from the outer base housing 300 to expose the consumer products stored within the interior volume 402.

The particular dimensions and proportions of the hybrid container are not critical. The proportions are preferably selected to provide a hybrid container which is sized to accommodate the particular items to be packaged therein. Thus, the actual hybrid container could be more elongated than shown in the drawings, or the hybrid container could be more nearly square, i.e., deeper than shown in the drawings. Preferably, however, the hybrid container is sized so it can be conveniently carried in a pocket, and held in a hand and opened by a consumer.

The items can be arranged in various ways. For example, the products could be arranged with the items overlapped or staggered relative to one another. Of course, if the products are small enough, they could be randomly placed in the interior volume 402.

The container could, of course, be used for a variety of products. One specific product for which the hybrid container can be used is smokeless pouched tobacco. Such tobacco can be provided in packets, sometimes known as “snus” and comprise individual packets of tobacco material.

It will be appreciated from the foregoing that there is provided an inexpensive pocket-size container capable of holding multiple items, and capable of being held and opened by a consumer.

It should be understood that the foregoing description is of the preferred embodiments, and is, therefore, merely representative of the article and methods of manufacturing the same. It can be appreciated that variations and modifications of the different embodiments in light of the above teachings will be readily apparent to those skilled in the art. For example, the inner ring 200 may have a bottom portion (not shown) to line the outer base housing bottom portion 306, the inner ring 200 may have a hollow wall, or the shape of the container my vary from circular to other shapes, such as cuboid or other polyhedron with smoothly rounded corners. Accordingly, exemplary embodiments, as well as alternative embodiments, may be made without departing from the spirit and scope of the articles and methods as set forth in the attached claims.
