Abstract
A dispensing system for dispensing cleaning product for hand sanitization comprises a cartridge having an internal reservoir for containing hand sanitization product, a nozzle configured in one of a plurality of key shapes, and a dispenser having a receptacle opening adapted to receive and engage the nozzle of the cartridge when the receptacle opening is configured in one of a plurality of key shapes corresponding to the key shape of the nozzle, the dispenser having a fluid communication passage for dispensing fluid for hand washing, whereby only cartridges and dispensers which have matched key shapes will engage each other for operative discharge of the hand wash cleaning product. The system includes a valve insert member which prevents leakage of fluid unless the nozzle key matches the receptacle opening. The valve insert member is in the form of a cup shaped member of elastomeric material, said member having a curved top having at least one slit having two slit edges, said slit defining a valve which is normally closed when the two slit edges are in mutual contact, but which slit edges separate when the curved top is penetrated, to thereby open the valve. Two slits can be provided in a cross-pattern.
