Abstract
Official abstract text for this publication.
A shut-off system for a dispenser includes a pinch member that moves relative to a guide and which is normally biased against a flexible outlet tube that is disposed therebetween. The flexible outlet tube that carries material, such as soap, supplied from a pump to an outlet nozzle. The pump and the pinch member are in operative engagement with an actuator, such that when the actuator is not engaged, the pinch member closes the outlet tube to prevent residual material retained in the outlet tube from flowing or drooling out of the outlet nozzle. Correspondingly, when the actuator is engaged, the pump is compressed, and the pinch member is moved away from the outlet tube, allowing the material to be pumped through the outlet tube and dispensed from the outlet nozzle.
