Kind Code:
A3
Abstract:
A shut-off system for a dispenser (10) includes a pinch member (70) that moves relative to a guide (60) and which is normally biased against a flexible outlet tube (56) that is disposed therebetween. The flexible outlet tube (56) that carries material, such as soap, supplied from a pump (53) to an outlet nozzle (54). The pump (53) and the pinch member (70) are in operative engagement with an actuator (58), such that when the actuator (58) is not engaged, the pinch member (70) closes the outlet tube (56) to prevent residual material retained in the outlet tube from flowing or drooling out of the outlet nozzle (54). Correspondingly, when the actuator (58) is engaged, the pump (53) is compressed, and the pinch member (70) is moved away from the outlet tube (56), allowing the material to be pumped through the outlet tube (56) and dispensed from the outlet nozzle (54).
