Abstract

The container includes a lower part and a lid. The lower part is of a single wall structure and is reinforced at its upper edge area by a reinforcing wall. The lower end of the reinforcing wall is curved inwards and extends into the side wall. Thus, an edge at the lower end of the edge area is prevented. The upper edges of the lid are also rounded and run smoothly into the reinforcing wall. The lid includes ribs which, when the lid is placed on the lower part, come to lie onto corresponding ribs of the lower part. The lid is connected to the lower part by a snapping mechanism. The lid includes an opening, into which a ledge of the snapping mechanism can be snapped in. This ledge is accessible through this opening to release the ledge to disengage the opening.
