Abstract: A selection valve (10) for use with a multi-chambered fluid container having outlet openings in communication with the fluid container chambers. The selection valve (10) utilizes an outer housing (12) having a bore (14) for receiving a fluid from the multi-chambered container. An upper gasket (20) engages an inner surface (16) of the outer housing (12) and an inner housing (28) having intake ports (34) that interface with the upper gasket, permitting communication between the outer housing (12) and the fluid container. A spring detent (46) is disposed upon the inner housing with protruding pins (48) that ride upon a rotating detent ring (50). When the housing (12) and the detent ring (50) rotate, the pins (48) enter radial grooves (54) and (55) causing the housing to remain at a desired location. A closure assembly is snapped onto the inner housing to permit a fluid path to be formed between a specific compartment in the container and the bore (14) in the outer housing.

Abstract: A selection valve (10) for use with a multi-chambered fluid container having outlet openings which are in fluid communication with the fluid container chambers. The selection valve (10) utilizes an outer housing (12) with a bore (14) therethrough for receiving a singular fluid from the multi-chambered container. An upper gasket (20) engages an inner surface (16) of the outer housing and an inner housing (28) having intake ports (34) interfaces with the upper gasket, thus permitting fluid communication between the outer housing and the fluid container. A molded spring detent (46) is disposed upon the inner housing with pins (48) protruding externally that ride upon a rotating detent ring (50). When the outer housing (12) and the detent ring (50) are rotated, the pins (48) are urged into radial grooves (54) and (55) thereby causing the housing to remain at a desired location.

Abstract: An inexpensive adapter enabling the facile manual switching of the fluid uptake port of a standard manually-operated fluid dispensing pump fluid between a plurality of fluid reservoirs. The adapter, which has a low internal dead volume, has an adapter outlet port that is in fluid communication with the fluid uptake port of the fluid-dispensing pump and at least two adapter inlet ports. The adapter inlet ports are in fluid communication with respective fluid reservoirs. The adapter has concentric outer and inner housings. In a preferred embodiment, the outer housing is non-releasably affixed to a fluid dispenser head while the inner housing is releasably affixed to a plurality of fluid reservoirs. The position of the outer housing, which is manually rotated with respect to the inner housing, is determined by means of a spring-loaded detent.
