Abstract
A fluid dispensing device comprising a body defining a cavity and a dispensing nozzle. A fluid discharging device is housed in the cavity. The fluid discharging device has a hollow casing defining a reservoir for containing a volume of fluid and a plunger slidingly engaged within the hollow casing. The plunger has a tubular portion which is arranged to extend from a first end of the hollow casing for co-operation with the dispensing nozzle. A biasing means is 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. A locking means holds the biasing means in a compressed state. Upon release of the locking means, the force stored in the biasing means is applied to the hollow casing thereby causing fluid to be ejected from the reservoir into the dispensing nozzle.
