A hand-operated, spray dispenser pump assembly for use on a container having an outwardly extending bead adjacent its top opening, for example, an aerosol-type can. The pump is attached to the container by means of a special snap-on closure member. The closure member is molded from a somewhat resilient, strong, thermoplastic material and includes a top wall having an opening for the stem of the pump and a depending skirt which is provided with an inwardly facing, annular bead on its inner walls adapted to be snapped over the outwardly extending, complementary bead on the top of the container. The pump is provided with an integral annular flange adjacent its top opening, which flange is snap fitted inside the special closure member. An annular rubber gasket is provided around the periphery of the pump flange and makes a leak-proof sealing engagement with the top opening in the container when the special closure is snapped down over the top of the container.
