Abstract
A liquid soap dispensing system includes a housing and a discharge mechanism for dispensing repeated doses of liquid soap from an associated cartridge. A receptacle is positioned in the cartridge wall forming an air path between the inside and outside of the cartridge, and a plastic filter is frictionally disposed within the receptacle for permitting air to flow into the cartridge but preventing soap from flowing out of the cartridge. The filter permits sufficient air flow into the cartridge to limit the vacuum therein to not greater than about 12' upon repeated operation of the discharge mechanism to prevent the cartridge walls from distorting.
