Abstract: A multiple adapter device is provided for use with a variety of tubular connectors. A body member adapted for connection to a catheter or container is provided with an adapter passage therethrough of a diameter convenient for use with relatively large connectors likely to be encountered during use of the catheter or container to which the device is attached. A flexible strap is secured on one end to the body member and extends outwardly. An adapter member having an adapter passage therethrough and having an outside diameter corresponding to the body member passage is secured to the strap a sufficient distance from the body member to permit the adapter member to be inserted into the body member passage by folding the strap. The adapter member passage has a diameter convenient for use with smaller connectors likely to be encountered during use of the catheter or container to which the device is attached.

Abstract: A flexible, collapsible container having walls essentially 0.01 to 0.03 inch thick and defining relatively thin lines of folding weakness in the container to facilitate flat collapse. The thickness of the lines of folding weakness is less than that of the surrounding walls. The cross-sections of the lines of folding weakness define arcs, the outer surfaces of which have a circumferential length which is 40 to 60 percent greater than the direct width of the lines of folding weakness. Preferably, the container is made of a relatively stiff polyolefin plastic such as polyethylene, polypropylene, or copolymers thereof of similar stiffness, particularly biaxially oriented materials.

Abstract: A molded collapsible solution container, which is made from a tubular, plastic parison, defines a body portion having an integral neck portion and shoulder portion at one end thereof. The container is sealed at its opposite end. The body portion defines, in as-molded configuration, a generally oval cross-section taken perpendicular to the axis of the container, adjacent the neck and shoulder portion. The cross-section tapers progressively to a flat configuration at the end of the container opposite to the neck and shoulder portion, which facilitates a uniform manner of flat collapsing of the container progressively from the opposite end toward the end adjacent the neck and shoulder portion as the contents thereof are withdrawn through the neck portion, when the container is disposed in neck downward position.
