[0044] In the drawing, in particular:

[0047] FIG. 3 is a schematic double sectional front view of the trash can of FIGS. 1 and 2;

[0048] FIG. 4 is a schematic sectional rear view of the trash can of FIGS. 1 to 3;

[0049] FIG. 5 shows another schematic partial sectional view, in particular of the front overhang edge segment of the trash can of FIGS. 1 to 4 as viewed from below;

[0050] FIG. 6 shows a further schematic partial sectional view, in particular of the back overhang edge segment of the trash can of FIGS. 1 to 5 as viewed from below; and

[0051] FIG. 7 is a schematic sectional view of the upper side of the trash can of FIGS. 1 to 6 as viewed from below.

[0052] The trash can 1 shown in FIG. 1 is provided with an injection-molded plastic body 2. This injection-molded plastic body 2 forms the 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 (see in particular FIG. 3) and a back side wall 6 (see FIG. 6).

[0053] The trash can 1 is also provided on its underside lower part 7 with a bottom wall 8 also formed by the injection-molded plastic body 2 (see for example FIG. 2). The side walls 3, 4, 5 and 6 extend from the bottom wall 8 up 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 adjacent the bottom wall 8 (with exemplary numbering).

[0054] Both lateral side walls 4 and 5 are integrally connected in two front corners 11 and 12 of the trash can 1 to the opposite front side wall 3 at two back corners 13 and 14 of the trash can 1 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 with a capacity of 240 l 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.

[0055] The opening 17 is surrounded by an overhang edge 21 that also forms an upper end of the trash can 12 and on which the lid is placed when the trash can 1 is closed.

[0056] At the same time, the overhang edge 21 allows insertion from underneath of lifting devices for lifting the trash can 1, for example when emptying the trash can 1 into a dumpster.

[0057] The overhang edge 21 has a collar 23 that projects outward in a radial direction 22 (only illustratively shown) from side wall 3 to 6. This collar 23 has a horizontal leg 24 projecting essentially perpendicular from side walls 3 to 6 and a vertical leg 25 bent downward and perpendicular, essentially at a right angle from the leg 24.

[0058] In an space 26 formed by the legs 24 and 25 between the collar 23 and side walls 3 to 6, a plurality of ribs 28 are positioned in a circumferential direction 27 of the overhang edge 21 and spaced along the overhang edge 21 that support the overhang edge 21, i.e. its collar 23. The ribs 29 have a longitudinal extension 29 in the vertical direction 9 of the side walls 3 to 6.

[0059] On the back side wall 6 above the bottom wall 8 there is an axial support 30 that supports a wheel axle (not shown) may be supported, so that the trash can 1 may also roll.

[0060] As is easily seen in FIGS. 2 to 4, the trash can 1 is characterized, with respect to its injection-molded plastic body 2 in this example, by at least a laminar surface reinforcement 35 formed by a flat material thickening 36. This material reinforcement 35 is such that the wall thicknesses of the trash can, while maintaining the capacity of 240 l like conventional trash cans, are reduced as a whole. This is in general specifically valid for side walls 3 to 6 of the trash can 1.

[0061] At the laminar surface reinforcement 36, the wall thickness of the trash can 1 is at least 3 mm, whereas the wall thickness of other unreinforced flat surfaces of the trash can 1 is less than 3.0 mm, preferably 2.75 mm.

[0062] The laminar surface reinforcement 35 is also configured so that it extends over both all of both front corners 11 and 12 and also an upper region 38 of the front side wall 3.

[0063] The longitudinal as well as the width extension of the laminar surface reinforcement are many times greater than its thickness. The longitudinal extension is aligned with the length of side surfaces 3 to 6 in the vertical direction 9, whereas the width extension is transverse to the direction 9. The thickness of the laminar surface reinforcement 35 corresponds to the wall thickness of both the front corners 11 and 12.

[0064] The upper region 38 extends as a flat upper belt 39 between both front corners 11 and 12 and connects these to each other such that the laminar surface reinforcement 35 forms a U-shaped surface structure 40 open toward the bottom wall 8, inside the injection-molded plastic body 2 on the front side wall 3 of the trash can 1.

[0065] At the same time, the front side wall 3 is formed by only a flat essentially rectangular window area 41 of reduced wall thickness. In this way, this less loaded flat window area 41 may be lighter.

[0066] Just one of the front corners 11 or 12 forms, due to its curved structure, the laminar surface reinforcement 35 as a three-dimensional surface structure 42, so that the injection-molded plastic body 2 becomes particularly torsion-proof.

[0067] The resistance or stability of the trash can is further increased since the laminar surface reinforcement 35 is integrated into the injection-molded plastic body 2 of the trash can 1, such that it is integrally connected to adjacent material regions 43 of the injection-molded plastic body 2, being joined in this way with edge portions 44 (only illustratively numbered) of front and lateral side walls 3 or 4 and 5. As an example, in this case, merge regions 45 between corners 11 or 12 and bottom wall 8 are also included.

[0068] This laminar surface reinforcement 35 extends and widens, starting from the underside 16, up to the upper side 16 of the trash can 1, so that the laminar surface reinforcement 35 is wider on the upper side 16 so that this upper side 16 is particularly resistant and stable.

[0069] Moreover, the flat upper belt 39 extends into regions 46 of the overhang edge 21 or into the front overhang edge segment 47 so that the overhang edge 21 is also strengthened by the laminar surface reinforcement 35 in one of the most heavily loaded positions. The front overhang edge segment 47 has in this case a material thickness of 3 mm.

[0070] The laminar surface reinforcement 35 is also and advantageously supported by an injection-molded grating structure 48, as in particular in the case of the front overhang edge segment 47 (see FIG. 5).

[0071] In particular, according to FIGS. 5 to 7, the structure of the trash can 1 is further partially reinforced by the plurality of ribs 28 with respect to the upper side 16, and the trash can 1 is characterized in that the ribs 28 spaced along the overhang edge 21 have different rib thicknesses 50 (only illustratively numbered with reference to FIG. 5).

[0072] The three front ribs 51, 52, 53 on the front overhang edge segment 47 have a rib thickness of 4.00 mm and therefore the greatest rib thickness of ribs 28 (see in particular FIG. 7).

[0073] The other directly adjacent ribs 54 and 55 above the front corners 11 and 12 on the overhang edge 21, on the contrary, already have a smaller rib thickness of 3.5 mm.

[0074] The other ribs 56 and 57 provided above the back corners 13 and 14 on the overhang edge 21 also have a smaller rib thickness with respect to the ribs 51, 52, and 53, provided on the front overhang edge segment 47. Their rib thickness is also less than the ribs 54 and 55 positioned above the front corners 11 and 12. The ribs 54 and 57 however have a greater rib thickness than other ribs 58 positioned between ribs 54 and 56 and 55 and 57, (only illustratively numbered) and the ribs 59 positioned between the ribs 56 and 57 (also only illustratively numbered).

[0075] These optimized ribs 28 also can improve the form stability and the weight of the trash can 1.

[0076] It is understood, that this embodiment is only a first embodiment of the inventive trash can. Insofar, the invention is not limited to this embodiment.

[0077] All characteristics disclosed in the application are claimed as essential to the invention, provided that they, individually or in combination, are new with respect to the prior art.
