ABSTRACT:
A container (34) includes first and second chambers (40, 42) for the storage of two substances (44, 46) such as medical liquids. The chambers are separated by a chamber-communicating assembly (61) which is selectively opened by an operator for mixture of the two substances and delivery to a patient. A leak detection compartment (62) encloses the assembly (61) between the two chambers, including a periperhal channel (76) and ridges (80) on the assembly (61).
When seal integrity between the container wall sheets (36, 38) and the assembly (61) is less than complete, the leak detection compartment both prevents liquid in one chamber from entering the other through the leak pathway and also assures detection of the leak during the manufacturing operation.
