Assignee:

Baxter Travenol Laboratories, Inc. - Deerfield IL

International Classification:

B65D 2508

US Classification:

206219

Abstract:

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.

Assignee:

Baxter Travenol Laboratories, Inc. - Deerfield IL

International Classification:

A61J 100

US Classification:

128272

Abstract:

A flexible, flat-collapsible bag containing parenteral solution may be adapted for aseptically receiving and mixing the contents of another container, with the flat-collapsible bag preferably initially containing, prior to receiving said contents, a liquid for parenteral administration in a volume of 30 to 70 percent of the holding capacity of said flat-collapsible bag. The bag defines at least a pair of access ports, one of the ports being sealingly connected to flexible, crimpable, thermoplastic tubing of a length of at least 11/2 inches, and a sealed connector member carried on the outer end of the flexible thermoplastic tubing, in which the seal connector member defines a sleeve including a sealing diaphragm in the bore thereof, with the sleeve constituting an extension of the flexible thermoplastic tubing. Accordingly, a piercing spike may sealingly enter the sleeve to rupture the diaphragm.

International Classification:

US Classification:

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.
