ABSTRACT:
A hand-held pump dispenser comprising a container having a neck portion, a pump assemblage including a piston and a tubular stationary cylinder member, the latter being adapted for disposition in the neck portion, and a resilient press-fit adapter carrying the cylinder member of the pump assemblage and arranged for insertion in the neck portion so as to make a tight press fit therewith. Interlocking means are provided on the cylinder member and on the adapter for enabling the latter to be snapped onto the member; additional means on the container neck and the adapter are provided for enabling the two parts, when assembled, to be snapped into the neck portion. The arrangement is such that all parts can be readily molded in simple mold cavities and easily assembled with a minimum of time and effort, and in the absence of special tooling or equipment.
