Abstract: The invention relates to an inadvertent-actuation locking arrangement in fluid dispensers. One problem that the invention overcomes is during non-use a user may inadvertently depress the activating part of the dispenser and thereby effect a discharge of fluid. In order to prevent this the invention has a closure cap which prevents the discharge of fluid. Specifically, the actuating member (54) carries an inadvertent-actuation locking element (104, 36) which is automatically engageable with an inwardly-displaceable portion (100) of the dispenser housing. When an associated closure cap (23) is seated about the discharge end of the dispenser during periods of non-use of the device, the housing portion (100) is inwardly-displaced by the cap into cooperative engagement with the locking element whereby movement of the actuating member (28) out of its first, outlet-closing position - and, accordingly, any release of stored fluid from within the dispenser interior - are prevented.

Abstract: The present invention relates to fluid dispensers and, more particularly, to hydraulically-driven, pump-like dispensers operable for manually-actuated, operator-controlled discharge of a stored, typically volatile fluid having characteristics that interfere with its ability to be readily contained. Heretofore known mechanically-pumped fluid dispensers for hydraulically discharging a stored fluid have been unable to contain or dispense highly volatile fluids. The present invention overcomes these deficiencies by providing a hand-held dispenser (10) which incorporates a flexible wall (66) or web-like barrier capable of containing a highly volatile fluid while accommodating mechanical and hydraulic dispenser-actuating deformations for initiating or effecting a discharge of the stored fluid. The barrier (66) 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 accommodating deformations in accordance with which a discharge of fluid from the dispenser is hydraulically effected.
