Abstract
A fluid dispensing device for dispensing a fluid form medicament formulation having a viscosity of from 10 to 2000 mPa·s, is disclosed having a housing and a fluid discharge device. The fluid discharge device is arranged to be actuated by one or more levers, so as to apply a force to the fluid discharge device which is used to move a container forming part of the fluid discharge device, along a longitudinal axis of the fluid discharge device to cause actuation of a pump forming. A pre-load mechanism prevents actuation of the pump until a pre-determined force is applied to each lever of sufficient magnitude to guarantee the production of a well-developed, efficient spray from the fluid dispensing device.
