  • Plastic coated mounting cup for spray button seal
    Patent number: 5881929
    Abstract: A mounting cup having a plastic film or laminate provided on the top outwardly facing surface thereof, at least adjacent the pedestal portion of the mounting cup, for mating with a skirt of a spray button to provide a sufficient seal between those two components during charging of a pressurized container with a propellant. The perimeter dimension of the skirt is preferably sized to be slightly smaller than the perimeter dimension of the pedestal portion of the mounting cup so that the skirt is slightly expanded upon engagement with the mounting cup. Due to this arrangement, the skirt at least partially bites into the plastic laminate, provided on the top surface of the mounting cup, to provide the sufficient seal between those two components.
