Abstract: A trigger sprayer may include a rotatable nozzle to facilitate the discharge of liquid from the nozzle in any desired direction and may also include a locking mechanism for preventing activation of the trigger sprayer. The trigger sprayer may also fit within the footprint of a container to which the trigger sprayer is attached.

Abstract: Fluid dispensing devices having a pump system connected to a container wherein the dispensing device may be operated with one hand using either a container having a griping surface or opening or a handle integrated with an actuator to facilitate one-handed use.

Abstract: 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.

Abstract: A nozzle has a front, a back, and at least one flat surface extending therebetween. A door is coupled to the intersection of the front and flat surface by a live hinge. Optionally, the door has a portal within which a screen is mounted. The exterior surface of the door is provided with one or more curved hooks and the flat surface is provided with corresponding number of mating slots with which the hook(s) engage(s). Preferably, the interior of the door is provided with one or more curved hooks and a corresponding number of mating slots are provided on the front of the nozzle on an edge opposite the live hinge. Preferably, the door is provided with a tab which extends outward beyond the periphery of the nozzle on the edge of the door opposite the live hinge.
