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 valve insert member for use in a cleaning product dispenser which dispenses a cleaning product, comprising: 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; andan extension piece extending radially from the cup shaped member along a fraction of the circumference of the cup shaped member,the cup shaped member sized to seat within an index block of the cleaning product dispenser, the index block further including a receptacle opening having one or more key slots to axially receive and engage a nozzle of a cleaning product cartridge having one or more key shapes corresponding to the key slots in the index block, such that the curved top of the valve is penetrated by the nozzle of the cleaning product cartridge to open the valve and permit dispensation of the cleaning product through the nozzle. 2. The member of claim 1, wherein the valve member comprises an elastomeric material of silicone. 3. The member of claim 2, wherein the valve member comprises a generally domed shape insert having a plurality of slits. 4. The member of claim 3, wherein the valve member has two slits. 5. The member of claim 4, wherein the slits are in a cross-pattern. 6. The member of claim 1, wherein the valve insert further includes skirt extending downwardly from the curved top and an enlarged diameter ring at a lower edge of the skirt. 7. The member of claim 1, wherein the fraction is about 1/20. 8. The member of claim 1, wherein the cup shaped member is sized to seat within the index block of the cleaning product dispenser such that when the nozzle includes key shapes that are not accepted into the key slots in the index block, the curved top of the valve is not penetrated by the nozzle of the cleaning product cartridge and the valve remains closed, thus preventing dispensation of the cleaning product. 9. A valve insert for a cleaning product dispenser, comprising: a normally closed, cup shaped valve member sized to be received into an index block of the cleaning product dispenser and that prevents the cleaning product from being dispensed when the valve member is closed, wherein the valve member includes 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,the index block of the dispenser including a receptacle opening having at least two key slots to fully receive and engage a nozzle of a cleaning product cartridge having one or more key shapes corresponding to the key slots in the index block,the cup shaped valve member sized to seat within the receptacle of the index block such that the valve member is opened by the nozzle of the cleaning product cartridge to permit dispensation of the cleaning product from the cleaning product cartridge when the nozzle includes key shapes that are fully received into the at least two key slots in the index block. 10. The valve insert of claim 9, wherein the valve member comprises a cup shaped insert. 11. The valve insert of claim 9, wherein the valve member comprises an elastomeric material. 12. The valve insert of claim 11, wherein the elastomeric material includes silicone. 13. The valve insert of claim 9, wherein the valve member comprises a generally domed top surface having at least one slit across the dome which is normally closed. 14. The valve insert of claim 13, wherein domed top surface has at least two slits forming a cross-pattern. 15. The valve insert of claim 9, wherein the valve member comprises a cup shaped insert having a rounded top surface, a downwardly depending skirt and an enlarged diameter ring at a lower edge of the skirt. 16. The valve insert of claim 9, wherein the fraction is about 1/20. 17. The valve insert of claim 9, wherein when the nozzle includes key shapes that are not fully received into the at least two key slots in the index block, the valve member is not opened by the nozzle of the cleaning product cartridge, thus preventing dispensation of the cleaning product from the cleaning product cartridge.
