Abstract
A container which can be easily filled and handled for the packing of two compositons which must be separately kept until mixed shortly before use, consists of two separate chambers which are arranged one upon the other in a packing unit. The upper chamber is provided with a closeable orifice for the delivery of the mixture. An intermediate part is arranged between the two chambers and such part has cutting edges or sharp mandrels on both sides thereof which allow the two compositions being separately kept to be mixed by cutting the bottom part of the upper chamber and the upper part of the bottom chamber when the container is pressed or screwed together.
