HINGED CONTAINER

摘要

A foldable container features a base and four lateral walls, with the lateral walls featuring trailing edges with latching elements and one or more ridges that extend from the trailing edge on the internal surface and/or close to the external surface and on lateral edges of the side wall. During stacking, the ridges mesh either between the latching elements and/or between two additional ridges so that stacked containers cannot shift in longitudinal direction. The trailing edges are designed in a step like shape and feature a protruding edge, by means of which a shifting in diagonal direction is also prevented. According to the invention, the containers are deformed less during transport and are easier to fold together. The invention facilitates stacking and folding by robots.

主权项

1. A foldable container with a base and four movable lateral walls that are connected to the base, which can be stacked and transported in a flat, outwardly unfolded condition, where the lateral walls can be swiveled from the outside to the inside, with the lateral walls each featuring an external and internal surface as well as two lateral edges and a top edge and a lower edge, with hinges arranged on the bottom edge of the lateral walls, by means of which the lateral walls can be folded upward from a flat orientation with the base and from horizontal position, and with the lateral edges of the lateral walls featuring latching elements for fixation of the upward folded lateral walls that are positioned at right angles to each other
wherein: the container comprises, on the lateral edges of at least two lateral walls opposite each other, a step shaped edge exhibiting a cantilever arm overhanging from the inside surface of the lateral walls and a vertically protruding edge from the internal surface of the lateral wall, with one or more protruding latching elements arranged on said step shaped edge and with the container either featuring one or more ridges, which extend vertically from the overhanging cantilever arm of the lateral wall and from the lateral edges of the lateral wall or the container featuring one or more ridges, wherein some ridges extend at right angles to the inside surface of the lateral wall and the other ridges extend at right angles away from the lateral edges of the lateral wall.
