ABSTRACT:
A liquid soap dispensing system includes a closed soap container having a manually actuated dispensing pump carried therebeneath. Refill of the container is by a plastic refill squeeze bottle with a neck defining an outlet opening closed by a membrane recessed therein. One embodiment of the bottle is formed by ultrasonically welding in the neck end, after the bottle is filled, a plug defining a cylindrical sleeve closed at the inner end thereof by a closure wall. The neck is inserted into a well in the top of the container, and a hollow piercing member at the bottom of the well ruptures the membrane or closure member, whereupon soap may be squeezed from the bottle and through the passage through the hollow piercing member, which is constricted by septa dividing the passage into channels such that flow of liquid soap therethrough at equal pressures at both ends of the passage is substantially inhibited. The piercing member is in sealing engagement with the plug sleeve, and annular ribs on the neck are in sealing engagement with the well side wall.
