Patent ID: 7302948

Claim:
A fluid dispensing device comprising a body defining a cavity and a dispensing nozzle, a protective end cap having an inner surface for engagement with the body to protect the dispensing nozzle, a fluid discharging device housed in the cavity for reciprocal movement between a rest position and an actuated position, the fluid discharging device having a hollow casing defining a reservoir for containing a volume of fluid and a plunger slidingly engaged within the hollow casing for movement relative to the hollow casing, the plunger having a tubular portion through which fluid is able to be ejected from the fluid discharging device when the plunger moves relative to the hollow casing and which extends from a first end of the hollow casing for co-operation with the dispensing nozzle, biasing means interposed between a second end of the hollow casing and an end wall of the cavity to bias the hollow casing towards the dispensing nozzle to move the fluid discharging from the rest position to the actuated position and cause relative movement of the plunger to the hollow casing, and a locking means to hold said biasing means in a compressed state wherein upon release of the locking means the force stored in the biasing means is applied to the hollow casing to move the fluid discharging device from its rest position to its actuated position thereby causing fluid to be ejected from the reservoir through the tubular portion of the plunger into the dispensing nozzle, wherein the fluid dispensing device is adapted to enable the fluid discharging device to return to its rest position from its actuated position against the bias of the biasing means and wherein the hollow casing has at least one outwardly extending detent for engagement with a complementary recess formed in the inner surface of the end cap so as to releasably hold the end cap in position on the body.
