A system for dispensing liquid soap comprising a closed wall structure defining a container with a partition separating the container into a lower liquid soap reservoir and an upper refill compartment. Dispensing means is carried by the container for dispensing liquid soap from the reservoir. A refill well having a refill aperture therethrough provides communication between the reservoir and the refill compartment and is dimensioned to permit the free flow of liquid soap therethrough. A pusher member is disposed in the refill well and extends upwardly toward the upper refill compartment to contact a refill cartridge containing liquid soap which has an outwardly extending neck defining an outlet with a tubular drain adaptor in the refill cartridge in sealing relation with the neck providing communication between the inside and outside of the cartridge. The tubular drain adaptor has a drain opening therein extending above the juncture of the neck with the remainder of the cartridge to facilitate draining of soap therefrom, and a stopper in the tubular drain adaptor slidable between a sealed position thereof wherein liquid in the refill cartridge is sealed therein and an open position thereof wherein the stopper is positioned away from the drain opening to permit free flow of soap therefrom. Various embodiments of the pusher member and the stoppers are shown.
