Patent ID: 8347879

Claim:
A fluid dispensing device for spraying a fluid into a body cavity comprising a housing, a nozzle at an upper end of the device for insertion into a body cavity, a fluid discharge device moveably housed within the housing, the fluid discharge device having a longitudinal axis and comprising a container for storing the fluid to be dispensed and a compression pump having a suction inlet located within the container and a discharge tube extending along the longitudinal axis for transferring fluid from the pump to the nozzle and at least one finger-operable lever pivotally supported at a lower end thereof on the housing so as to be pivotable into the housing, transversely with respect to the longitudinal axis of the fluid discharge device, from a rest position to an actuated position to apply a force to an actuating member connected to a neck of the container to cause the container to move upwards along the longitudinal axis towards the nozzle so as to actuate the compression pump, wherein a pre-load is formed between the at least one lever and the actuating member to prevent pivoting of the at least one lever from the rest position to the actuated position for actuation of the compression pump until a predetermined force is applied to the at least one lever, wherein the actuating member and the at least one lever have surfaces which slidingly interact when the at least one lever pivots from the rest position to the actuated position to cause the container to move upwards along the longitudinal axis, wherein the pre-load is formed by one of the surfaces having first and second surface portions on which the other surface successively slides as the at least one lever pivots from the rest position to the actuated position, and wherein the first surface portion is steeper than the second surface portion.
