Soap dispensing system
First Claim
1. A system for dispensing liquid soap comprising a closed wall structure defining a container, partition means separating said container into a lower liquid soap reservoir and an upper refill compartment, dispensing means carried by said container for dispensing liquid soap from said reservoir, a refill aperture in said partition means providing communication between said reservoir and said refill compartment, a refill cartridge containing liquid soap and having an outlet, and slot and key mechanism carried by the end of said refill cartridge outlet and said container for maintaining said cartridge in a predetermined refill configuration and in communication with said refill aperture, said refill cartridge being removably enclosed within said refill compartment in a refill configuration with the end of said refill cartridge outlet disposed for cooperation with said refill aperture to permit flow of liquid soap from said refill cartridge to said reservoir thereby to refill said reservoir.

Abstract
A liquid soap dispensing system includes a closed soap container having a manually actuated dispensing pump carried therebeneath, the container being separated by a partition into a lower soap reservoir and an upper refill compartment, the latter adapted to enclose therein a removable refill cartridge and having a downwardly extending refill will with a plurality of keys upstanding from the bottom thereof. The cartridge has an outlet neck, the outer bottom surface of which has a like plurality of slots. The neck is closed by a pierceable membrane recessed therein and adapted to be received into the well so that a cartridge opening member pierces the membrane to accommodate free flow of liquid soap from the cartridge to the reservoir. The cartridge is entirely closed to define the liquid level in the reservoir at the bottom of the neck, and a drain hole in the reservoir wall above the bottom of the neck but below the tops of the keys prevents bootleg cartridges from being used in the soap dispenser. A slot in the wall of the refill compartment prevents the accumulation of free liquid soap therein.

- 1. A system for dispensing liquid soap comprising a closed wall structure defining a container, partition means separating said container into a lower liquid soap reservoir and an upper refill compartment, dispensing means carried by said container for dispensing liquid soap from said reservoir, a refill aperture in said partition means providing communication between said reservoir and said refill compartment, a refill cartridge containing liquid soap and having an outlet, and slot and key mechanism carried by the end of said refill cartridge outlet and said container for maintaining said cartridge in a predetermined refill configuration and in communication with said refill aperture, said refill cartridge being removably enclosed within said refill compartment in a refill configuration with the end of said refill cartridge outlet disposed for cooperation with said refill aperture to permit flow of liquid soap from said refill cartridge to said reservoir thereby to refill said reservoir.
- 4. A system for dispensing liquid soap comprising a closed wall structure defining a container, partition means separating said container into a lower liquid soap reservoir and an upper refill compartment, dispensing means carried by said container for dispensing liquid soap from said reservoir, a refill well extending downwardly from said partition means having a refill aperture therein providing communication between said reservoir and said refill compartment, and a refill cartridge containing liquid soap and having an outwardly extending neck defining an outlet, one of said refill well and the bottom of said neck having a key extending therefrom and the other having a slot therein shaped to receive said key, said refill cartridge being removably enclosed within said refill compartment in a refill configuration with the bottom of said neck disposed for cooperation with said refill well and with said key in said slot to permit flow of liquid soap from said refill cartridge to said reservoir thereby to refill said reservoir.
- 12. A system for dispensing liquid soap comprising a closed wall structure defining a container, partition means separating said container into a lower liquid soap reservoir and an upper refill compartment, dispensing means carried by said container for dispensing liquid soap from said reservoir, a refill well extending downwardly from said partition means having a refill aperture therein providing communication between said reservoir and said refill compartment, the inner bottom surface of said refill well having a key extending upwardly therefrom, and a refill cartridge containing liquid soap and having an outwardly extending neck defining a tubular outlet the outer bottom surface thereof forming a slot shaped to receive said key, said refill cartridge being removably enclosed within said refill compartment in a refill configuration with said key in said slot to permit flow of liquid soap from said refill cartridge to said reservoir thereby to refill said reservoir.
- 17. A system for dispensing liquid soap comprising a closed wall structure defining a container, partition means separating said container into a lower liquid soap reservoir and an upper refill compartment, dispensing means carried by said container for dispensing liquid soap from said reservoir, a refill well extending downwardly from said partition means having a portion of the inner bottom surface thereof forming a key and having a refill aperture therein providing communication between said reservoir and said refill compartment, an upwardly extending cartridge opening member in said refill well having the outer peripheral surface thereof spaced from the inner surface of said well and connected thereto by said key extending therebetween, and a refill cartridge containing liquid soap and having an outwardly extending neck with the outer bottom surface thereof having a slot therein shaped complementary to said key and defining an outlet having a closure member therein, said refill cartridge being removably enclosed within said refill compartment in a refill configuration with said neck disposed in the space between said cartridge opening member and the inner surface of said refill well with said key in said slot and said closure member opened by contact with said cartridge opening member to permit flow of liquid soap from said refill cartridge to said reservoir thereby to refill said reservoir.
- 21. A liquid soap dispenser comprising a closed wall structure defining a container, partition means separating said container into a lower liquid soap reservoir and an upper refill compartment, dispensing means carried by said container for dispensing liquid soap from said reservoir, and a refill well extending downwardly from said partition means having a portion of the inner bottom surface thereof forming a key and having a refill aperture therein providing communication between said reservoir and said refill compartment.
- 26. A liquid soap dispenser comprising a closed wall structure defining a container, partition means separating said container into a lower liquid soap reservoir and an upper refill compartment, dispensing means carried by said container for dispensing liquid soap from said reservoir, a refill well extending downwardly from said partition means having a portion of the inner bottom surface thereof forming a key and having a refill aperture therein providing communication between said reservoir and said refill compartment, and an upwardly extending cartridge opening member in said refill well having the outer peripheral surface thereof spaced from the longitudinally extending inner surface of said well and connected thereto by said key.
- 29. A refill cartridge comprising a vessel in the shape of a polyhedron having parallel top and bottom walls and a plurality of planar side walls substantially normal to said top and bottom walls, and a neck extending outwardly from said bottom wall with the outer bottom surface of said neck having a slot therein.
- 32. A refill cartridge comprising a semirigid vessel generally in the shape of a polyhedron having parallel top and bottom walls and a plurality of planar side walls substantially normal to said top and bottom walls, a quantity of liquid soap in said vessel, a neck defining an outlet extending from said bottom wall having at least one slot in the outer bottom surface thereof, and a closure member in said neck retaining said liquid soap in said vessel.
