Abstract
A plastic container with a bottom and, connecting continuously onto the edge thereof a standing wall of random shape defining an upper circular edge portion on which can be placed a cover provided with a peripheral groove for receiving the edge portion, the cover and the edge portion being provided with co-acting locking elements. The locking elements include on the one hand by a number of L-shaped locking members distributed uniformly over the periphery, one leg being fixed to the cover or to the edge portion of the container such that it is oriented perpendicularly to the bottom, and on the other hand by an outward pointing lip on the edge portion or the cover and against which the other leg of the locking member can be placed. The cover can be lifted relative to the container during filling of the container, while for its permanent closure the cover is positioned on the upper circular edge of the container and turned through a determined distance relative to the container in order to place all the locking members simultaneously in contact with the co-acting lip, whereby the cover is locked onto the container.
