Multiple chamber container with inner diaphragm and intermediate chamber

摘要

A two chamber container for the separate storage and selective mixing of two components is disclosed. The container includes two outer flexible thermoplastic sheets and an inner, diaphragm sheet. A unique seal line structure is formed between one of the outer sheets and the inner, diaphragm sheet. A peelable barrier structure such as a sheet of aluminum foil with an inner layer of adhesive is secured to the exterior surface of the exterior wall of the container at that portion of the other of the outer sheets which defines one of the chambers of the container. The peelable barrier sheet permits the use of lower cost materials for the remainder of the container structure while both (1) permitting visual inspection of the chamber contents and (2) providing high moisture, gas and light barrier properties.
