Abstract
A manually-operated dispenser for user-controlled discharge of an internally-stored fluid includes a variable length assembly normally driven to its maximum longitudinal extension for fluid-tightly closing a fluid discharge opening and a vent opening disposed at opposite ends of an elongated housing, a piston bounding an end of an internal fluid reservoir and operatively movable along the housing for volumetrically reducing the reservoir and for driving stored fluid toward and through the discharge opening, and an actuator assembly manually operable by the user for causing controlled foreshortening of the variable length assembly whereby the fluid discharge and vent openings are concurrently opened permitting the forced discharge of a correspondingly controlled volume of stored fluid. An associated dispenser end closure cap incorporates a movable shuttle assembly for protectively receiving and substantially fluid-tightly enclosing an applicator integrally carried on the dispenser when the cap is operably emplaced on the dispenser for storage between fluid discharging uses thereof.
