A fluid dispensing device (5, 105, 205, 305, 405, 505) for dispensing a fluid form medicament formulation having a viscosity of from 10 to 2000 mPa.s. is disclosed and comprises a housing (9, 109, 209, 309, 409, 509) and a fluid discharge device (8, 108, 208, 308, 408, 508) arranged to be actuated by one or more levers (20, 21; 120, 121; 170; 220, 221; 320, 321; 420, 421; 520) to cause actuation of a pump forming part of the fluid discharge device. A pre- load means (28; 27, 28; 39,40; 41, 42, 44; 144, 47a, 47b; 150, 152, 153; 224, 227; 342; 424x, 446; 425a; 427, 428; 560, 561) is used to prevent 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.

L'invention porte sur un distributeur de (5, 105, 205, 305, 405, 505) de médicaments fluides d'une densité de 10 à 2000 mPa.s. Le distributeur comporte un boîtier (9, 109, 209, 309, 409, 509); un dispositif d'éjection du fluide (8, 108, 208, 308, 408, 508) pouvant être actionné par un ou plusieurs leviers (20, 21; 120, 121; 170; 220, 221; 320, 321; 420, 421; 520) agissant sur une pompe faisant partie du dispositif d'éjection; un moyen de précharge (28; 27, 28; 39,40; 41, 42, 44; 144, 47a, 47b; 150, 152, 153; 224, 227; 342; 424x, 446; 425a; 427, 428; 560, 561) empêchant d'actionner la pompe avant qu'une force prédéterminée d'une intensité suffisante ne soit appliquée sur chacun des leviers, de manière à garantir une pulvérisation efficace et suffisament puissante.
