The trigger sprayer may also fit within the footprint of a container to which the trigger sprayer is attached.

Rotating sprayer and methods for using the same

A trigger sprayer having six parts: (i) a dip tube, (ii) a valve, (iii) a flexible pump diaphragm having a circumferential valve lip, (iv) a shroud having a trigger, an element which engages the diaphragm, and front and rear mating elements, (v) a body having a closure for a container, an inlet coupled to the dip tube, a valve seat for the valve, an element which engages the valve lip, a discharge barrel having a proximal opening into which the valve lip seats, a vent chamber, a vent barrel coupled to the vent chamber, a rear mating structure coupling to the rear mating element of the shroud so that the shroud can pivot, and a forward mating element, and (vi) a combination nozzle and door assembly with a nozzle which couples to the fluid discharge barrel of the molded body, and has a trigger locking element.
