A source of liquid soap for washbasins and the like is provided by a flexible, collapsible bag filled with liquid soap. A hollow needle is penetrably inserted through the material of the bag, which penetration develops a seal about the needle. The needle is connected through a conduit to a dispenser for the soap. A source of vacuum in communication with the conduit, the force of gravity or a force externally imposed upon the bag to compress it, actuates a flow of soap from the bag through the needle for discharge from the dispenser. As liquid soap is evacuated from the bag, the bag collapses. Upon depletion of the soap, the needle is withdrawn and inserted into a replacement bag of soap.
