DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

As shown in Fig. 1, embodiments of the present invention provide a collapsible trash can, comprising a plurality of side panels 10, a base 40, and an upper frame 30. The upper frame is formed as a hollow rectangular ring structure. The side panels are vertically oriented and fit with the curved side panel 20.
Assembly begins with a base 40 having an insertion channel 41 which receives vertical panels. In a stowed mode, the upper frame 30 has an upper frame storage indent 45 that engages a base storage slot 42 of the base 40. When a user transforms the trashcan from stowed mode to deployed mode, the user first removes the base 40 and inserts the pair of side panels 10, then the curved side panels 20 into the insertion channel 41. The insertion channel 41 is formed on the periphery of the base 40. Pair of side panels 10 and the curved side panels 20 have engaging rails 11 that clip to each other via four panel retainer clips 50. The side panel lower edge 13 inserts into the insertion channel 41. The upper insertion edge 12 analogously fits into an insertion channel 41 of the upper frame 30. The upper insertion channel of the upper frame and the lower insertion channel of the base can be congruent or symmetrical. After the user installs the panels onto the base, the user slides the panel retainer clips over the pair of engaging rails to lock the four sidewalls together.
As seen in Fig. 2, the upper frame 30 benefits over the side panel 10 and the curved side panel 20 and the panel retainer clips 50. The upper frame 30 can have indents that receive the upper tips of the panel retainer clips 50 and the upper edges of the engaging rails 11. The user presses the upper frame 30 downwardly onto the base 40.
As seen in Fig. 3, the panels include a front side panel 21, a rear side panel 22, a right side panel 23, and a left side panel 24. The base 40 also has a molded set of indents for the legs, namely a front right leg socket 46, a front left leg socket 47, a rear right leg socket 48, and a rear left leg socket 49. Each of the leg sockets may have an opening for a screw or other similar type of connector for connecting the socket and base to the legs. The retainer clip junction 25 has detail that is shown in figure 4.
As seen in Fig. 4, the side panel 10 or the curved side panel 20 can connect to a side panel 10 or another curved side panel 20. The curved side panels 20 are connected to each other in the stowed mode, and the curved side panels 20 have a side panel 10 between them in the deployed mode.
The first panel has a first engaging rail contact face 18 that contacts a second engaging rail contact face 19 of the second panel. The first engaging rail contact face 18 is parallel to the second engaging rail contact face 19. The engaging rail 11 then has a first engaging rail inside face 16 extending at a right angle to the first engaging rail contact face 18, while the second engaging rail inside face 17 extends at a right angle to the second engaging rail contact face 19. The first engaging rail inside face 16 is preferably parallel to and flush to the second engaging rail inside face 17. The first engaging rail tip 14 extends at a right angle from the first engaging rail inside face 16 and extends toward the first panel 91. The second engaging rail tip 15 extends at a right angle from the second engaging rail inside face toward the second panel 92.
The retainer clip junction 25 shows how the first panel 91 is connected to the second panel 92. After aligning the first panel 91 to the second panel 92, a user slides panel retainer clips 50 over the pair of engaging rails 11. The first engaging rail 93 has a first channel 55, and the second engaging rail 94 has a second channel 56. The engaging rails are biased toward each other such that the first engaging rail contact face 18 abuts the second engaging rail contact face 19. The panel retainer clips 50 have a first extending arm 51 that extends along the first engaging rail inside face 16 and the first engaging rail tip 14. Similarly, a second extending arm 52 extends along the second engaging rail inside face 17 and the second engaging rail tip 15. The first extending arm 51 ends with a first extending tip 53 that bends around and locks to the first engaging rail tip 14. Similarly, the second extending arm 51 ends with a second extending tip 54 the bends around and locks to the second engaging rail tip 15. Preferably, the first extending tip 53 biases toward the second extending tip 54 so as to clip the pair of engaging rails 11 together.
As seen in Fig. 5, the panel retainer clips 50 can be full-length and connect a side panel 10 to a pair of curved side panels 20 at a lower insertion channel 41 of the base 40. Similarly, the side panel upper edge 12 can engage the upper frame 30.
As seen in Fig. 6, the insertion channel 41 can receive a curved side panel 20 or a side panel 10 in a snap fit retainer 43. The snap fit retainer 43 can be formed as a protrusion on the insertion channel 41 which hooks onto and retains a side panel lower edge. The side panel lower edge can be a double folded rim of the side panel 10 or the curved side panel 20. The snap fit retainer 43 can be sized to allow removal, such as in case of user error during assembly, or when the user wants to convert the collapsible trashcan from the deployed mode to the stowed mode. The side panel lower edge 13 is slightly thicker than the side panel.
As seen in Fig. 7, the insertion channel 41 can permanently receive a side panel when the side panel lower edge 13 is formed as a larger curved structure. Again, the snap fit retainer 43 can be sized to allow manual removal, or removal with tools.
As seen in Fig. 8, a top view of the panel shows that the panel extends outwardly with an engaging rail contact extension 111, then an engaging rail inside extension, then ending at an extending tip edge 113.
As seen in Fig. 9, the lid frame 60 has a lid hatch 61, a lid hatch sensor 62 and a lid hatch indicator 63. The lid frame 60 fits over the upper frame 30. The legs 70 can also be attached to the base, including a first leg 71, a second leg 72, a third leg 73, and a fourth leg 74.
As seen in Fig. 10, a stowed mode of the collapsible trashcan includes a storage container 80 having a first packaging panel 81, a second packaging panel 82, a third packaging panel 83, and a fourth packaging panel 84 for protecting the contents. The base 40 and the lid frame 60 sandwich the upper frame 30. The legs 70 can be placed inside the lid frame 60. The storage slot 42 engages the upper frame 30. The panel retainer clips 50 can be formed as short clips or as long strips. The length of the panel retainer clips, which can be formed as panel retainer strips can be sized according to the biasing force desired. The panel retainer clips can be formed of a folded panel of metal. The curved side panel 20 has a pair of bends such that its engaging rails 11 extend at a right angle. A pair of curved side panels 20 can thus be clipped together using clip formed as a short clip or a long strip. Panel retainer strips are preferred for larger more permanent panel structures, while panel retainer clips are preferred for smaller structures that are easier to take down. The storage container hollow 85 is formed between the pair of curved side panels 20. The flat side panels 10 can rest between the lid and the second package panel 82. The rounded corners of the curved side panels 20 provide structure to protect the fragile plastic parts inside including the base 40, and the upper frame 30.
By having a deployed mode and a stowed mode, the user can have a storage option for their trashcan when not in use and receive a smaller shipping package.
