  • Patent number: 5110013
    Abstract: A container and method for changing liquid cleaning compounds into a dispensing apparatus employs a blow molded plastic container that includes a filling inlet and a discharge outlet. The discharge outlet is a fitting adapted to snap onto a quick connect coupling and includes a tube that extends to the bottom of the container. The tube is inserted into the container while it is still hot. As the container cools, it shrinks forming a tight seal around the tube. The coupling snaps onto the outlet and sealingly engages it. The opposite end of the coupling is attached to the dispenser which acts to evacuate the cleaning compound from the container. Upon depletion of the cleaning compound within the container, the coupling is separated from the container. Since the coupling includes a one-way valve, cleaning compound within the tube is not released. This provides a closed system for dispensing cleaning compounds deterring misuse.
