ABSTRACT:
The instant invention, is directed to a liquid dispensing system, especially for soap. The system comprises a housing, and a flexible pouch for storing liquid which is held within the housing and which has a discharge nozzle. A mechanism for pumping the liquid from the pouch is operatively associated with the housing. A valve mechanism for checking the flow of the liquid from the pouch includes a mechanism for laterally tensioning the pouch proximate its discharge nozzle so that the tension created is greater than a static pressure head of the liquid in the pouch but less than the dynamic pressure head created by the pumping mechanism.
