ABSTRACT:
A dispenser of the hand-held type for discharging fluid under pressure, comprising a container having an open top end, and a valve assemblage which is received in the open end and secured in place by means of a crimped ferrule. The container has a circular rim surrounding the opening, together with an annular external shoulder immediately adjacent the rim. The valve assemblage includes a valve housing defining a valve chamber, a resilient valve seat which constitutes one end of the chamber, and a movable valve stem having a longitudinal opening and transverse side passage adapted to communicate with the chamber when the stem is depressed. The housing further includes an annular mounting flange which engages and rests upon the rim of the container, and a depending skirt which bears against inner wall portions of the container, all to form a leakproof seal therewith. The ferrule extends over the annular mounting flange of the valve housing and is crimped onto the external shoulder of the container. The arrangement is such that only a single crimping operation is employed, instead of the two previously required in the fabrication of conventional can-type, valved dispensers.
