ABSTRACT:
A small hand-held dispenser of the pump variety, comprising a container and a cooperable dispenser pump construction adapted to be carried by the container. The pump per se is secured therein by means of a unique plastic closure which is in the form of an inverted, dish-shaped member. The closure has relatively thin walls enabling it to be readily molded, and has a depending peripheral flange with an internal bead which is forced over an external shoulder on the rim of the container so as to effect a snap fit therewith. In one embodiment, the flange has a depending portion which extends downward a substantial distance beyond the location of the internal bead, so as to minimize the likelihood of the flange being cracked either during or after the forced bypass of the bead and container shoulder. The plastic closure not only securely mounts the pump assemblage, but also effects a leak-proof connection with the container while at the same time simplifying the assembly operations and tooling.
