Abstract:
A dispenser for transferring a liquid from a container; comprising:a dispenser body having a first end, a second end and an inner surface, the first end having an aperture through which the dispenser body is capable of receiving at least a portion of the liquid; a nozzle slideably engaged with the second end of the dispenser body and capable of ejecting at least a portion of the liquid contained in the dispenser body while the nozzle is being depressed generally toward the first end of the dispenser body; and a valve stem slideably disposed within the dispenser body in engagement with the inner surface proximate to the first end for movement between a first position and a second position, while the nozzle is being depressed generally toward the first end of the dispenser the valve stem moves to the first position and substantially obstructs the aperture to generally prevent the liquid from flowing through the aperture, while the nozzle is being displaced away from the first end of the dispenser body the valve stem moves to the second position causing the aperture to be at least partially unobstructed by the valve stem so that the dispenser body is capable of receiving the liquid, wherein the valve stem includes at least one projection extending generally outwardly and slideably abutting the inner surface of the dispenser body to limit the motion of the valve stem between the first and second positions to linear motion within the dispenser body.
