Title: Hand-held dispenser pump construction

Abstract: A small hand-held dispenser of the pump variety, comprising an aerosol-type can and a cooperable dispenser pump construction adapted to be carried by the can. The pump per se is snap-fitted into a unique plastic closure which is in the form of an inverted, dish-shaped member that in turn is assembled to the can by a snap assembly operation. The plastic closure has relatively thin walls enabling it to be readily molded, and has a depending peripheral flange which is forced over the top curled rim of the can so as to effect a snap fit therewith. The plastic closure not only securely mounts the pump assemblage on the can, but also effects a leak-proof connection therewith while at the same time simplifying the assembly operations and tooling.
