초록 ▼

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.

1. A dispensing system for dispensing cleaning product for hand sanitization comprising: a cartridge having an internal reservoir for containing hand sanitization product, and a pump assembly, including a nozzle having a tip through which product exits and configured in one of a plurality of key shapes;a dispenser having a block with a receptacle opening adapted to axially receive and engage the nozzle of the cartridge when the receptacle opening is configured in one of a plurality of matching key shapes corresponding to the key shape of the nozzle, the dispenser having a fluid communication passage for dispensing fluid for hand sanitization; anda normally closed valve member in the block which prevents fluid from discharge, but which opens to permit fluid discharge when the nozzle has a matching key shape to the block and wherein the nozzle is fully axially received in the block, wherein the valve member comprises a main body formed in the shape of a cup and an extension piece extending radially from the cup along a fraction of the circumference of the cup, whereby only cartridges and dispensers which have matched key shapes will engage each other for operative discharge of the hand sanitization product, and open the valve member. 2. The dispensing system of claim 1, wherein the valve member comprises a cup shaped insert. 3. The dispensing system of claim 1, wherein the valve member comprises an elastomeric material. 4. The dispensing system of claim 1, wherein the valve member comprises an elastomeric material of silicone. 5. The dispensing system of claim 1, wherein the valve member comprises generally domed shaped insert having at least one slit across the dome which is normally closed. 6. The dispensing system of claim 5, wherein domed shaped insert has at least two slits in a cross-pattern. 7. The dispensing system of claim 1, wherein the valve member comprises a cup shaped insert having a rounded top surface, a dependency skirt and an enlarged diameter ring at a lower edge of the skirt. 8.
