Description

[0024] In the drawing, in particular:

[0025] FIG. 1 is a schematic and perspective view of a trash can with three side walls joined at two corners and corrugated in the width direction the side walls;

[0026] FIG. 2 is a schematic perspective view of the bottom wall of the trash can of FIG. 1,

[0027] FIG. 3 a schematic bottom view of the bottom wall of the trash can, of FIGS. 1 and 2; and

[0028] FIG. 4 is a further schematic and perspective cross- sectional view of a lower part of the trash can of FIGS. 1 to 3.

[0029] The trash can 1 shown in FIG. 1 is provided with an injection-molded plastic body 2. This injection-molded plastic body 2 forms side walls 3, 4, 5 and 6 of the trash can 1, i.e. a front side wall 3, a first lateral side wall 4, a second lateral side wall 5 and a back side wall 6. The trash can 1 is also provided on its underside 7 with a bottom wall 8 also formed by the injection-molded plastic body 2. The side walls 3, 4, 5 and 6 extend from the bottom wall 8 upward in a direction 9, and the side walls 3, 4, 5, 6 are integrally connected with this bottom wall 8 at their respective lower ends 10 (with exemplary numbering). Both lateral side walls 4 and 5 are connected in two front corners 11 and 12 of the trash can 1 to the front side wall 3 and in two back corners 13 and 14 of the trash can 1 are integrally connected to the opposite back side wall 6. The side walls 3, 4, 5 and 6 as well as the bottom wall 8 are positioned with respect to each other such that they define together a cavity 15 for holding trash. This cavity 15 may be accessed from the upper side 16 of the trash can 1 through an opening 17 and may be closed by an unillustrated lid. The lid may be rotatably attached by a support 18 embedded in two handles 19 and 20 of the trash can 1 on the same trash can 1. The opening 17 is surrounded by an overhang edge 21 that at the same time represents an upper end of the trash can 1 on which the lid is placed when the trash can 1 is closed. At the same time, the overhang edge 21 allows the insertion of lifting devices for picking up the trash can 1, for example when emptying the trash can 1 into a dumpster. An axial support 22 is also provided (see also FIGS. 2 and 4) on the back side wall 6 above the bottom wall 8 for holding an unillustrated wheel axle, so that the trash can 1 may also roll.

[0030] As can readily be seen in FIGS. 1 to 4, the front side wall 3 and both lateral side walls 4 and 5 in this example are provided with corrugations between the two corners 11 and 12 (front side wall 3), 11 and 13 (first lateral side wall 4) and 12 and 14 (second lateral side wall), in a width direction 25 (illustrated for side wall 3 only, see in particular FIG. 3) of these side walls 3, 4 and 5, at least in a region 26 at their lower ends 10 close to the bottom wall 8. In this way, these side walls 3, 4 and 5 achieve a higher resistance and therefore the trash can 1 has an overall higher rigidity. Above these regions 26, these side walls 3, 4 and 5 have a more planar form, so that they are produced there with less material. This region 26 in this example is characterized by a height 27 that is approximately 1/9 of the entire height 28 of the respective side wall 3, 4 or 5. These side walls 3, 4 and 5 are provided, between the respective two corners 11 and 12, 11 and 13 and 12 and 14 in the width direction 25, with alternating valleys 30 and ridges 31, and the ridges 31 form corresponding peaks 32 and the valleys 30 corresponding wave troughs 33 on the side walls 3, 4 and 5. For example, the front side wall 29 of the trash can 1 is formed on this outer side 29 with three peaks 32 and four troughs 33. Both lateral side walls 4 and 5, between the respective corners 11 and 13, 12 and 14 on the outer side 29 are formed with only two peaks 32 and three troughs 33. In this sense, these side walls 3, 4 and 5 are provided in the width direction 26 of the respective side wall with a labyrinthine side wall cross section 34, and the front side wall 3 is provided with a tighter labyrinthine side wall cross section 35 than the lateral side walls 4 and 5 which have a wider labyrinthine cross section 36 (numbered for illustrative purposes only). Moreover, a merge region 37 (numbered for illustrative purposes only) is also formed with a corrugation between the side walls 3, 4 and 5 and corrugated edge segments 38 (numbered for illustrative purposes only) of an edge 39 enveloping the bottom wall 8 (see in particular FIG. 3).

[0031] In particular, the bottom wall 8 is also reinforced in that it is provided with a plurality of further wave peaks 40 and troughs 41 that extend, with respect to their respective width direction 42 (shown for illustrative purposes only), starting from a central area 43 of the bottom wall 8 and in this example also from an injection point 44 provided on the bottom wall 8, like spokes to the merge region 37 between the bottom wall 8 and the side walls 3, 4, 5 and 6.

[0032] It is understood that this embodiment is only a first embodiment of the inventive trash can. In this sense, the invention is not limited to this illustrated embodiment.

[0033] All characteristics that are disclosed in the application files are claimed as essential to the invention, provided that they, individually or in combination, are new with respect to the prior art.
