Patent attributes
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.
