[0027] Reference is made herein to the attached drawings. Like reference numerals are used throughout the drawings to depict like or similar elements of the can stacking device. For the purposes of presenting a brief and clear description of the present invention,the preferred embodiment will be discussed as used for a can stacking device. The figures are intended for representative purposes only and should not be considered to be limiting in any respect.

[0028] Referring now to FIG. 1, there is shown a perspective view of an embodiment of a can stacking device. In the shown embodiment, the can stacking device 1000, comprises a frame 100 having an outer wall 130 and one or more inner walls 140 disposed between a top end 110 and a bottom end 120, such that the frame 100 is sized and proportioned to circumscribe one or more cans within the boundary of the outer wall 130. In the shown embodiment, the inner walls 140 seamlessly blend into the outer wall 110 at a junction to define one or more sub-divisions 150 that are configured to receive the ends of cans inserted from both the top end 110 and the bottom end 120 of the frame 100. In an alternative embodiment, a portion of the outer wall 130 is absent between adjacent junctions (see FIG. 5). In one embodiment, a partition is disposed between the top end 110 and the bottom end 120 of the frame 100, wherein the partition 160 is disposed within each sub-division 150 to provide a flat surface that can rest on the top end a can inserted through the bottom end 120 of the frame 100, and simultaneously provide a flat surface to support the bottom end of a second can inserted from the top end of the frame 100. In the shown embodiment, the partition 160 is planar along 110 an entire surface thereof, however in alternative embodiments the partition 160 may have any shape. For example in one alternative embodiment, the partition 160 is non-planar and includes a shape that conforms to standardized can geometry. In one embodiment, the partition 160 is disposed midway between the top end 110 and the bottom end 120 of the frame 100. In an alternative embodiment, the partition 160 is disposed towards one of the top end 110 and the bottom end 120 of the frame 100.

[0029] In the illustrated embodiment the can stacking device 1000 is made from an injection mold so that the frame 100, outer wall 130, inner wall 140, sub-divisions 150, and planar partitions 160 are all included as part of one monolithic structure. Furthermore in the shown embodiment, the frame 100 is obround shaped, such that the outer wall 130 is 3.36 mm thick and has two semi-circles of radius 37.75 mm on opposite ends attached by two longitudinal sides each of length 75.5 mm. Additionally, the inner walls 140, also 3.36 mm thick, are also semi-circles of radius 37.75 mm such that they integrate with the outer wall 130 to define two ring-shaped sub-divisions 150 of radius 37.75 mm. These dimensions allow precisely two identical ring-shaped sub-divisions 150 to fit within the frame 100 without intersecting, such that within each ring-shaped sub-division 150 the planar partition 160 is formed by a protruding inner lip that extends radially inward 5.25 mm to create a flat surface along the inner circumference while leaving a circular opening 200 of radius 32.5 mm between the top end 110 and the bottom end 120 of the obround shaped frame 100.

[0030] Although the protruding lip style planar partitions 160 do not fully cover the area within each ring-shaped sub-division 150, the surface area provided by the protruding lip style partitions 160 is sufficient for an appropriately sized can between 65 mm and 75.5 mm across to rest on without risk of failing through the circular opening 200. More specifically these ring-shaped sub-divisions 150 are intended to receive cylindrical cans having radii between 32.5 mm and 37.75 mm. The protruding lip style partitions 160 are configured to rest on the top ends of appropriately sized cylindrical cans inserted from the bottom face 120 and to support appropriately sized cylindrical cans inserted from the top end 110, such teat such that the two cans are separated and securely stacked one on top of the other.

[0031] Referring now to FIG. 2A, there is shown a perspective view of an embodiment of a can stacking device with three ring-shaped sub-divisions utilizing the protruding inner lip style planar partition for each ring-shaped sub-division. The illustrated embodiment shows an alternate version of a can stacking device 1000 that includes three ring-shaped sub-divisions 150 and employs three protruding lip style planar partitions 161. This embodiment can be used to stack three cans at a time, one more than in the embodiment previously mentioned. In other embodiments the number of ring-shaped sub-divisions 150 can be further increased to facilitate the stacking of more cans.

[0032] Referring now to FIG. 2B, there is shown a perspective view of and an embodiment of a can stacking device with two ring-shape sub-divisions utilizing the continuous disc style planar partition for each ring-shaped subdivision. The illustrated embodiment shows an alternate of a can stacking device 1000 that includes two ring-shaped sub-divisions 150 and employs a continuous disc style planar partitions 162 in each ring-shaped sub-division, such that there is no opening between the top end 110 and the bottom end 120 of the obround shaped frame 100. This embodiment can be used to simultaneously stack cans of varying size. More specifically, this embodiment can facilitate stacking of any cylindrical can whose radius is less than or equal to the radius of the ring shaped sub-division 150. In an alternative embodiment, the continuous disc style planar partitions 162 may comprise apertures or recesses thereon for seating a received can therein.

[0033] Referring now to FIG. 3, there is shown a perspective view of an embodiment of a can stacking device where one can is being inserted into a ring-shaped sub-division from the top end and another can is being inserted into a ring-shaped sub-division from the bottom end. In the illustrated embodiment of a can stacking device 1000 the protruding lip style partitions 160 are configured to rest on the top end 311 of a first appropriately sized cylindrical can 310 inserted from the bottom face 120 into a ring-shaped sub-division 150 and to support the bottom end 322 of a second appropriately sized cylindrical can 320 inserted from the top end 110 into the opposite end of the same ring-shaped sub-division 150, such that such that the two cans 310, 320 are separated by partition 160 and securely stacked one on top of the other. In use multiple can stacking devices 1000 are stacked in tandem. For example, another can stacking device 1000 can be installed underneath the first can 310 and a third can stacking device 100 can also be installed above the second can 320, such that the two-level high stack of cans can be more easily handled.

[0034] Referring now to FIGS. 4A, 4B, 4C, and 4D there are shown a top view, a front view, a right-side view, and a close-up cross-section of the outer wall of an embodiment of a can stacking device taken along line A-A of FIG. 4A, respectively. In the illustrated embodiment, the outer wall 130, and the inner walls 140 that are combined to form the ring-shaped sub-divisions 150 are tapered to facilitate easier removal from the injection mold during the manufacturing process. The partition 160 is the thickest point on the outer wall 130, or inner wall 140, and as the wall extends toward the top end 110 or the bottom end 120 the thickness decreases because both walls 130, 140 taper inward. FIG. 4D shows where the thickness is greatest at the partition 160 and highlights the inward taper on both the external and internal portions of the outer wall 130.

[0035] While forming the ring-shaped sub-divisions 150, the outer wall 130 and inner wall 140 of the obround shaped frame 100 also form a plurality of triangular apertures 170 disposed between the ring-shaped sub-divisions 150 and the outer wall 130. The triangular apertures 170 are intentionally included in the frame 100 during injection molding to reduce the amount of material consumed during the manufacturing process while reinforcing the structure of the frame 100 and sub-division 150. Additionally, the apertures 170 create a convenient hand hold that can be used as a handle when moving the can stacking device 1000. Furthermore, when several cans are stacked one on top of the other such that several can stacking devices 1000 are placed in between the cans and on the ends of the outermost cans, the stacked cans can be secured together by running a fastener through the apertures 170 so that the can stacking devices 1000 and the cans there between are fastened together.

[0036] Referring now to FIG. 5 there is shown a perspective view of an embodiment of a can stacking device having no outer wall portion. In the illustrated embodiment the can stacking device 1000 is comprised of two adjacent ring-shaped sub-divisions 150 with no outer wall 130. Wherein the ringed shape of the two sub-divisions 150 is defined by a shared an inner wall 180, such that each ring 150 is incomplete without the other and the shared wall 180 serves as the sole point of connection between the sub-divisions 150.
