Abstract
A trigger pump dispenser comprises a body, an outlet nozzle, a pump chamber, a piston for defining a variable volume in the pump chamber, a trigger coupled with the piston by interconnection means, and biasing means for biasing the trigger to a retracted position. The trigger is movable to cause the piston to pump liquid into and out of the pump chamber for dispensing through the outlet nozzle. The piston is interchangeably associatable with the trigger and the pump chamber so that different length pistons are usable to determine different maximum fill volumes of the pump chamber.
