  • Closure delivery system
    Patent number: 5672162
    Abstract: A system for the introduction of a fluid to an internal volume of a suction canister. The canister is provided with sidewalls and a top, the latter possessing a circular opening and cylindrical duct. A fluid-containing vessel is provided having a tubular extending dispensing port sized to pass over and capture the cylindrical duct when the fluid-containing vessel is positioned over and in contact with the suction canister. The fluid-containing vessel further is provided with a fluid reservoir segregated from the tubular extending dispensing port by a circular membrane which is scored so as to rupture by the cylindrical duct upon the application of nominal pressure exerted upon the fluid-containing vessel.
