Abstract
A trigger operated dispensing device for the discharge of fluids, particularly in a spray. The device comprises a housing including a trigger, which actuates a flexible pump. The flexible pump has an inlet accepting the fluid and an outlet end through which the fluid passes going to the discharge. The flexible pump, preferably of bellows type, is situated in line with and just adjacent to the discharge wherein rotational motion of the trigger results in rotational compression of the pump chamber. In a particularly preferred embodiment, the flexible pump further includes mechanical structure for imparting a radial momentum to the fluid prior to discharge.
