Abstract: A non-returnable container is made from at least two dish-shaped parts which have outward facing flanges joined together by a sealed seam and is intended for holding liquid and/or pasty, granular and/or powdery substances. The flanges of the dish-shaped parts, which are made of a metal-plastic composite are joined together by means of at least one sealed seam and are held in a bent position by means of a holding device.

Abstract: A multi-chamber pack comprising at least two chambers separated by a frangible partition and externally operable means for breaking the partition, and means for mixing the contents of the chambers. The mixing means are formed by an agitator element operative by rotation, more particularly one or more vanes, said element being disposed rotatably in one of the chambers. An actuating element is disposed rotatably on the outside of the pack and is coupled to the agitator element so as to rotate therewith and serves to drive the latter. The means for breaking the partition are in the form of a push rod fixed to an inwardly deformable wall part of the pack.
