FIELD OF THE INVENTION
This invention relates generally to the field of promotional products or toys and more specifically to a system of interconnecting a plurality of beverage cans in a modular fashion. The present invention allows beverage cans to be easily assembled into combined modular units for display thereof or for building various structures such as playhouses, forts, or the like.
BACKGROUND OF THE INVENTION
It has been observed that there exists an overabundance of waste materials produced by our society and that means to re-utilize these materials, has for a large part, been overlooked. In recent years, the concept of recycling has gained momentum wherein basic consumer goods such as paper, plastic, glass, aluminum, or the like may be re-instituted into the consumer product chain, thus alleviating the load on the environment. Moreover, as we have become more of a disposable product based society, it has become more important to re-use all the materials we can and in all possible ways. Adding to this is pressure be more responsible with our common resources, especially materials that particularly lends themselves to recycling such as aluminum, paper, glass, and plastic. It has further been observed that our society produces a rather large amount of beverage cans such as those for the containment of soft drinks, beer, or other consumable juices. Research has shown that as many as 156 billion cans were produced in the year of 2003 yet only 42% of these cans were recycled.
In order to provide a use for empty beverage cans, various designs have been suggested which allows a plurality of beverage cans to be releasably mounted one upon another in a modular fashion. U.S. Pat. No. 3,815,281 to Kander, U.S. Pat. No. 4,170,082 to Freedman, U.S. Pat. No. 4,474,491 to Ferrarelli, and U.S. Pat. No. 4,764,143 to Gat, et al. disclose various beverage can stacking devices having varying types of releasable retention mechanism for releasable attachment of the top and bottom ends of a conventional beverage can. However, all of these devices are capable of interconnecting only one can co-axially to another can; the interconnecting of additional cans which are disposed laterally relative thereto must be accomplished via complicated and cumbersome interconnect mechanisms whose retentive strength would most likely degrade due to extended use. Moreover, the interconnect mechanisms as described in the aforementioned patents do not allow a plurality of cans which are laterally interconnected relative to one another to be optimally “packed” together in order to form a building block with minimal spacing therebetween.
Another drawback is that the aforementioned beverage can stacking devices are not easily adapted for packaging and sale along with the beverage product. Each of the stacking devices must be purchased separately from the canned beverage product, thereby diminishing the likelihood of consumer acceptance.
Yet another drawback of the aforementioned designs is that neither device discloses a top portion can engagement member having an annular depression formed therein for resilient retainment of the upper lip of a top portion of a beverage can therein in conjunction with a bottom portion can engagement member for resilient friction engagement of the bottom portion of a beverage container disposed coaxially thereabove. This aspect of the prior art, by itself, reveals a salient utilitarian ramification. The prior art can stacking devices having annular depressions formed in both of the coaxially disposed can engagement members would optimally retain only the top portion of a conventional can, thus inverting the longitudinal orientation of the proceeding can therebeneath, which in turn would hinder the ability to stack additional cans above or below. Moreover, can stacking devices having hollow, cylindrically shaped members formed in both of the coaxially disposed can engagement members would not employ the enhanced releasable securing feature of an annular depression for optimal retainment of the lip portion of a conventional can therein.
SUMMARY OF THE INVENTION AND OBJECTIVES
In accordance with the present invention, there is disclosed a modular beverage can interlocking device comprising a plurality of ring-shaped members, wherein each ring-shaped member has an upper orifice and a lower orifice which provides reliable retention for the bottom end and top end of a conventional beverage can respectively in a substantially co-axial orientation. A plurality of fillets interconnect said plurality of ring-shaped members in a generally co-planar orientation thereby allowing a plurality of said beverage cans to be interconnected side-by-side with respect to each other, such that when the lower orifices of each of said plurality of ring-shaped member are populated with said plurality of beverage cans, a modular style building block is formed which is adapted for stacking, one upon another.
Preferably, the ring-shaped members are disposed in at least one column of multiple evenly spaced linear rows whereby the interlocking device having the lower orifices of the ring-shaped members thereof populated with cans forms a generally rectangular shaped block which is easily interconnected with other populated interlocking devices. Additionally, means are described to allow the usage of varying styles or sizes of beverage cans via multiple inwardly facing annular slots of differing diameter, which are adapted to engage the lip of said can therein.
One aspect of the present invention is a beverage can stacking device that is easily adapted for packaging and sale along with conventional beverage product. The present invention's novel design provides for the selective retention of a plurality of beverage cans, which is optimally suited for dense packaging of the beverage product, as well as having minimal cost, thereby enhancing the likelihood of distribution by beverage producers. The beverage can stacking device allows for selective retention of a plurality of beverage cans in any one of a plurality of configurations such as the so-called six-pack, which can be easily stored or transported. Following removal of the beverage product, the device may then be used for modular stacking of empty beverage cans.
Thus a primary object of the present invention is to provide a means of promoting cans to be recycled into productive useful items.
Another object of the present invention is to provide a beverage can interlocking device which is adapted for packaging and sale of beverage cans having product stored therein.
Another object of the present invention is to provide a means of connecting cans into a repeatable functional unit of building.
Another object of the present invention is to provide a creative promotional item for shipping and selling of liquids in cans.
A further object of the present invention is to provide a means of displaying can collections in a organized manner.
Another object of the present invention is to provide a modular style beverage can interlocking device which obviates the disadvantages of the prior art while providing a device which is inexpensive to manufacture, and thus inexpensive to the end user.
Other objects and advantages of the present invention will become apparent from the following descriptions, taken in connection with the accompanying drawings, wherein by way of illustration and example, preferred embodiments of the present invention are disclosed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now to the drawings, a modular beverage can interlocking device embodying one preferred embodiment of a device according to the instant invention is designated generally by the reference numeral 10. The beverage can interlocking device 10 is generally shown in FIG. 1 having a plurality of ring-shaped or generally cylindrically-shaped members 12 interconnected via integrally formed inner fillets 13. All members 12 are substantially co-planar in orientation having a lower orifice 15 and an upper orifice 16. The upper orifice 16 has an upper lip retention portion which provides for releasably secure placement of the upper lip 21 of a conventional beverage can 20 thereinto. The lower orifice 15 on the other hand, is adapted for releasably secure placement of the bottom portion 22 of a another can thereinto via a snug friction fit. The lower orifice 15 is also adapted to provide sufficient spacial clearance to allow placement of the upper lip 21 into the upper lip retention portion when inserted through the lower orifice 15 as best shown in FIGS. 4 and 5.
The orientation of the device 10 relative to the releasably secured beverage cans 20 as shown in FIGS. 2 through 5, is defined as a distribution orientation due the ability of packaging a plurality of beverage cans together in a manner that is optimally suited for distribution or sale thereof. Wherein today's beverage product packaging schemes usually entails a package offering to consumers, such as the typical six-pack, the device 10 allows multiple beverage cans to be packaged together in an easily stackable manner. The ability of the device to allow packaging of beverage product provides an enhanced, distinct utility by providing incentive for the purchase of the beverage product, as well as to increase availability of the modular beverage can interlocking device per se to consumers.
Following removal of the beverage cans from the device 10 for consumption of its contents, the empty can may be releasably secured to the device in a building block orientation as best shown in FIGS. 6 through 9. That is, the cans 20 may be releasably secured to the device via insertion thereof through the upper orifice. Thus, the device 10, which has cans that are releasably secured thereto through the lower orifice is defined as the distribution orientation, and the device, which has cans that are releasably secured thereto through the upper orifice is defined as the building block orientation. When the device 10 is populated with cans in the building block orientation, a building block 25 is formed that may be interconnected with other building blocks that are adapted to be stacked upon each other in order to create visual displays of the beverage cans or as a toy to challenge the creative ability of young children.
The modular beverage can interlocking device of the present embodiment is shown having a total of six ring-shaped members 12 which are integrally formed from one piece into two columns of equally spaced linear rows having three members 12 thus forming a two-by-three type configuration; however, other types of integrally formed configurations are possible including a one-by-two configuration, a one-by-three configuration, a one-by-four configuration, or the like. Nevertheless, it is to be appreciated that virtually any type of configuration could be realized including two-by-five, three-by-six, and the like using the concepts and teachings of the present invention. Additionally, it is contemplated that that other geometric configurations such as three ring-shaped members 12 disposed equilaterally apart and maintained in a generally co-planar relation to each other by fillets thereby forming a triangular shape would also be a valid alternative. A further novel concept of the present invention is the ability of the fillets 13 to be selectively cut by a user using a saw or knife in order to split the interlocking device 10 into a plurality of smaller interlocking devices. For example, an interlocking device 10 having a two-by-three configuration may be split by a user into two devices, each having a one-by-three configuration.
FIG. 10 depicts how building blocks of various configurations may be intermingled in order to form a structure, wherein the type of structure formed therewith is limited only by the user's creative ability. As shown, the plurality of building blocks exist as differing types of configurations, and each is populated with beverage cans having indicia or labeling printed thereon, which differs from an adjacently disposed building block in order to uniquely delineate one building block from another. Thus, building blocks 25a, 25b, 25d, 25e, 25e, 25h, 25i, 25j, 25k, 25l, 25m and 25n exist as a two-by-three configuration, blocks 25f, and 25g exist as a two-by-four configuration, blocks 25c, and 25o exist as a two-by-two configuration, and block 25p exists as a one-by-two configuration. As shown, building blocks 25a, 25b, 25c, 25d, 25e, and 25f form a base for the subsequent placement of other building blocks thereupon. Block 25g is placed on top of block 25b, 25c, and 25d in a “straddling” fashion such that the overall structural integrity of the overall structure is enhanced, wherein blocks 25h, 25i, and 25j are placed on top of blocks 25d, 25e, and 25f in a similar manner. Additionally, other blocks (25k, 25l, 25m, 25n, 25o, and 25q) are positioned over the structure and are ready for placement thereon. Blocks 25o, and 25p show a two-by-two, and one-by-two configuration respectively that may be created by severing predetermined fillets of a device which was originally of a two-by-three configuration.
The upper lip retention portion, which exists within each ring-shaped member 12 will now be described. FIGS. 5, and 9 depict cross-sectional views in which each ring-shaped member 12 is populated with cans in a distribution and building block orientation respectively. As shown, the upper lip retention portion, preferably has an annular slot 23 formed within the inner wall of member 12, which is dimensioned to accept the upper lip 21 of a conventional can therein with a snug, snap-fit. Although the upper lip retention portion provides releasable securement means for a beverage can via a annular slot 23, it will be appreciated by those skilled in the art that other structures such as protruding embossments or snap tabs may be utilized which effectively form a detent mechanism for providing a snap-fit of the upper lip 21 of the can to member 23. Additionally, it may be seen that the upper lip retention portion releasably secures the upper lip to member 23 whether inserted from the lower orifice or upper orifice.
To provide for a snap type fit of the upper lip 21 to portion 23, the device 10 is formed from a resilient thermoplastic exhibiting sufficient resiliency to allow for slight deformation thereof during insertion of the beverage can. The device 19 may be formed of any known thermoplastic material having sufficient resiliency to allow for slight deformation thereof during insertion of the beverage can thereinto. One preferred material used for forming the present embodiment was polyurethane, having a hardness from 95 shore A as measured by ASTM (American Society for Testing and Materials); however, it is to be understood by those skilled in the art that there are numerous types of thermoplastic formulations having varying hardnesses which would be suitable for this purpose.
An additional feature provided by the generally frusto-conical shape of the ring shaped members 12 is the ability to stack multiple devices 10 one upon another in a relatively dense manner. Thus, the upper orifice 16, which is generally smaller in diameter then the lower orifice, may be easily placed thereinto, wherein FIG. 12 shows four devices which are stacked one upon another.
Another embodiment 30 of the present invention is shown in FIGS. 13 through 15, which includes an optional stacking retention mechanism which allows multiple devices to be selectively secured together while stacked one upon another. The optional stacking retention mechanism provides utility by enhancing the structural integrity of a plurality of devices that are arranged in a stack such as is shown in FIG. 15. For example, usage of the optional stacking retention mechanism provides for multiple interlocking devices to be easily handled or processed within a manufacturing line for canned beverage products. The ring-shaped members 12, and fillets 13 are functionally similar to the device 10 of FIGS. 1 through 12. The embodiment of FIGS. 13 through 15 differs however in that an optional ring stacking mechanism, and stacking force distribution ledges for enabling the stacking of a plurality of devices 30 one upon another. Thus, consumers or users of the device may be able to store multiple devices in a reasonably stable manner. The optional stacking retention mechanism preferably has a plurality of distally spaced, upwardly extending projections 31, which are preferably integrally formed on each of the fillets 13, are adapted for releasably secure placement into a corresponding plurality of depressions 32 via a snug, friction fit. As best shown in the cross-sectional view of FIG. 15, the depressions 32 extend upwardly into the fillets 13, and have a cross-sectional size that is essentially similar to the cross-sectional size of the projections 31. Although the projections 31, and depressions 32 are adapted to provide a friction type fit, it will be understood by those skilled in the art that the relative shape and size thereof may be easily altered in order to provide a snap-fit or other similar type releasable retention means. As shown, a cross-sectional view of three interlocking devices which are stacked, one upon another such that the projections 31 of one device 30 are each impaled into a corresponding depression 32 of another device 30 disposed thereabove.
Additionally, the device 30 may optionally include a plurality of stacking force distribution ledges for evenly distributing the downward forces placed upon the interlocking device 30, from a another device 30 resting thereupon. The stacking force distribution ledges provide a means to provide even support for the entire periphery of all the ring-shaped members 12 of another device 30 that is stacked thereabove. The stacking force distribution ledges preferably comprises a plurality of upwardly extending tabs 33, which are radially spaced around the periphery of each ring-shaped member 12. As best shown in FIG. 15 the tabs 33 provide even support for another device which is disposed above the device 30 from which the tab 33 is interconnected to.
Another alternative embodiment 40 of the present invention contemplates a handle mechanism which provides for easy manipulation by the hand of a user as shown in FIGS. 16 through 19. The ring-shaped members 12, and fillets 13 are functionally similar to the embodiment of FIGS. 1 through 12, however the embodiment of FIGS. 16 through 19 differs in that a handle mechanism is included, which incorporates finger holes 41 for manipulation by the hand of the user. Each of the finger holes 41 generally comprise a through hole, which is formed in a web-like, membrane 42, which extends between, and is bounded by the outer periphery of adjacent ring-shaped members 12, and their associated fillets 13. Each of the holes 41 are sufficiently large to allow placement of a finger or thumb of the user thereinto, and preferably incorporates an integrally formed annular ring 43 for relieving the stress placed upon the finger of a user, during the lifting operation. Each of the web-like membranes 42, and their associated annular rings 43 are preferably integrally formed with the ring-shaped members 12 and associated fillets 13 during manufacture. In use, a device 40, which is typically populated with canned beverages may be easily lifted and transported in the normal manner by inserting a finger into each of the holes 41. Following transport of the populated device to its desired destination, the beverages may be consumed and the device 40 re-populated with empty cans in order to form a building block as previously described.
The present invention may be embodied in other specific forms without departing from the spirit or scope of the invention. Therefore, the described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is therefore, indicated by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
