ABSTRACT:
A user-controlled manually-actuatable pumpable dispenser for hydraulically-driven discharge of a stored fluid incorporates a flexible wall or web-like barrier capable of containing a highly volatile fluid while accomodating mechanical and hydraulic dispenser-actuating deformations for initiating or effecting a discharge of the stored fluid. The barrier is formed of a relatively thin wall of polytetrafluoroethylene (PTFE) material having a predetermined thickness selected so as to render the barrier sufficiently flexible for accomodating deformations in accordance with which a discharge of fluid from the dispenser is hydraulically effected.
