Stack container

Abstract

The invention relates to a stack container for transporting and storing objects, said container consisting of a rectangular base with side walls rising vertically from the bottom edges, with the top edge of the side walls being designed to be cantilevered outwards as a support surface for the rim of a second identically constructed container which is also cantilevered outwards and surrounds the base, said container being characterized in that the upper side of the top edge of the side walls and the underside of the rim surrounding the base are formed complementary to one another in such a way that, over the extension of the container circumference, partial surfaces of the top edge and the rim are designed differently in their angle of inclination, such that the corner areas of both the top edge and the rim surrounding the base are formed horizontally between two adjacent side walls each, whereas between the corner areas the top edge and the rim are designed at least in parts such that they are obliquely inclined outward and downward at an angle from the level of the horizontal corner area.

Claims

1. A stack container for transporting and storing objects, said container comprising: (a) a rectangular base having bottom edges; (b) side walls rising vertically from the bottom edges and forming a top edge cantilevered outwards to form a support surface; and (c) a rim surrounding the base and having an underside formed complementary to an upper side of the edge of the side walls, the rim being cantilevered outwards; wherein partial surfaces of the top edge and the rim have different angles of inclination, such that corner areas of the top edge and corner areas of the rim surrounding the base are formed horizontally and intermediate areas between the corner areas have inclined partial sections obliquely inclined outward and downward at an angle from the horizontal corner area, and wherein the inclined partial sections merge into a horizontal configuration in outer edge areas of the partial sections.

2. The stack container according to claim 1, wherein a transitional area between the horizontal corner areas and the inclined partial sections (6, 6′), in vertical projection from above, is formed in a triangular, obliquely extending pattern.

3. The stack container according to claim 1, wherein the top edge of the side walls forms a flange.

4. The stack container according to claim 1, wherein the side walls are reinforced on outer sides of the side walls by horizontal and vertical ribs arranged below the outwardly projecting top edge.

5. The stack container according to claim 1, wherein the container is made of plastic material by injection molding.

Description

(1) The present invention is elucidated in sufficient detail and depicted by way of the following figures, where

(2) FIG. 1: shows a section of a stack container as a perspective representation;

(3) FIG. 2: illustrates the upper corner area of a container shown in FIG. 1;

(4) FIG. 3: shows the bottom corner area of a container as per FIG. 1;

(5) FIG. 4: is a partial view of two containers stacked on top of each other according to FIG. 1.

(6) FIG. 1 shows a stack container for which the reference numeral 1 is used in general. It consists of a base 2 and side walls 3 extending upwards from the base 2. The side walls 3 have a top edge 4, which is provided with its outwardly cantilevering support surface for a container 1 which is identical in construction and placed on top of container 1.

(7) As is clearly illustrated in FIG. 2, the top edge in the corner area between two adjacent side walls 3 is designed as a horizontal surface 5. The edge areas adjoining the horizontal support surface 5 to the respective sides have an inclined outward and downward slope and are provided with the reference numeral 6.

(8) The transition between the horizontal support surface 5 and the obliquely inclined partial surface 6 is formed by an obliquely inclined, approximately triangular surface 7 in both circumferential direction and perpendicular to it.

(9) As can be seen from FIG. 3, in which the container is shown rotated by 180°, the extensions of the corner area and the adjoining lateral edge areas are designed complementary to the top edge, although the corner area 5′ is not designed here as a full-surface area but is open towards the bottom, with a web-like rib 8 being provided to reinforce this area. The areas complementary to the top edge are marked here with reference numerals 6′, 7′.

(10) In FIG. 4 a situation is illustrated in which two identical containers 1 are placed on top of each other, with the complementary extension of the top edge of the lower container 1 and the bottom edge of the upper container 1 being exactly matched to each other.

(11) As is particularly evident from FIG. 1, the side walls 3 are reinforced by vertical ribs 9 and horizontal ribs 10.
