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 well with a pair of opposed keys extending thereinto. The cartridge has an outlet neck, the outer surface of which has a pair of opposed 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.
