Liquid soap dispensing system
First Claim
1. In a liquid soap dispensing system including a housing and a discharge mechanism carried thereby for movement between a normal retracted configuration and an actuating configuration for dispensing liquid soap from an associated cartridge, the improvement comprising:
- latch means carried by said housing for movement between a latching condition engageable with the associated cartridge for locking it in a dispensing position on the housing and an unlatching condition, and bias means interconnecting said latch means and the discharge mechanism for resiliently urging said latch means to its latching condition and said discharge mechanism to its retracted configuration.

Abstract
A liquid soap dispensing system includes a molded plastic housing adapted to receive a disposable refill cartridge containing liquid soap. Rails on the housing engage in recesses on the cartridge to guide vertical movement of the cartridge to its mounted use position, in which position it is latched by a latch member pivotally carried by the housing and engageable with the outlet neck of the cartridge. The neck carries a compressible discharge nipple engageable by a pump member actuated by a handle for discharging soap. Bias means holds the latch means in its latched condition and the pump member and handle in their normal rest positions. The dispenser includes a minimal number of parts which can be assembled without the use of fasteners. A key is provided for releasing the latch member to permit removal of a spent cartridge.

8. A liquid soap dispenser having only a minimal number of parts which can be assembled without the use of fastening means for dispensing liquid soap from an associated cartridge which has a compressible outlet nipple, said dispenser consisting essentially of:
- a housing member having a receptacle portion and adapted to receive the associated cartridge in a use position with the nipple in said receptacle portion, a pump member freely receivable in said receptacle portion and movable therein between a pumping position for compressing the nipple to discharge liquid soap therefrom and a release position out of engagement with the nipple, a handle member carried by said housing member in a supported condition for engagement with said pump member, said handle member in its supported condition being pivotally movable between an actuating position for driving said pump member to its pumping position and a retracted position for accommodating movement of said pump member to its release position, said pump member in its pumping position accommodating free movement of said handle member to and from its supported condition on said housing member, said pump member and said handle member cooperating when engaged to retain said pump member in said receptacle and to retain said handle member in its supported condition, and a bias unit engageable with said housing member and said pump member for resiliently urging said pump member to its release position and into engagement with said handle member, thereby to urge said handle member to its retracted position.
