ABSTRACT:
A trigger sprayer comprises a dispenser body, a pump mechanism adjacent the dispenser body, and a trigger adjacent the pump mechanism. The pump mechanism including a pump element moveable relative to the dispenser body between first and second positions. The trigger is connected to the pump element and moveable between first and second positions wherein movement of the trigger to its first position causes movement of the pump element to its first position and movement of the trigger to its second position causes movement of the pump element to its second position. The trigger sprayer is configured so that a first application of force by a user is needed to move the trigger from the first position to the second position and a second application of force by a user is needed to move the trigger from the second position to the first position. The trigger has first and second finger engaging portions and a finger receiving opening for receiving at least one finger of a user. The finger receiving opening is at least partially defined by the first and second finger engaging portions. The finger engaging portions are configured and positioned so that pushing against the first finger engaging portion in a first direction moves the trigger toward its first position and pushing against the second finger engaging portion in a second direction opposite the first direction moves the trigger toward its second position.
