Abstract

A unique container is disclosed which has at least three chambers for the separate storage and selective mixing of at least two components. The container includes two outer flexible sheets and an inner, diaphragm sheet, all sealed about their peripheries in the preferred embodiment. Multiple breakable lines of securement are formed between one of the outer sheets and the inner, diaphragm sheet. Multiple permanent lines of securement are formed between the inner diaphragm sheet and the other outer sheet, extending substantially parallel to and substantially the length of the respective breakable lines of securement. Such a container structure defines two chambers which have no common boundary and an intermediate chamber. In the preferred embodiment of the invention, the intermediate chamber does not store any substance; rather, it serves as a buffer or barrier chamber and also acts as a test for seal integrity. In another embodiment of the invention, the intermediate chamber holds a third component for mixing.
