Abstract: When the reciprocable plunger of the pump is locked down in its fully depressed position, the lowermost tip of the plunger maintains the inlet ball check valve of the pump forcefully pressed against its seat to prevent leakage. Spindly legs on the hollow plunger adjacent the tip thereof define inlet orifices for the discharge passage of the plunger during operation and provide a spring-like action for generating the ball hold down force. As the tip engages the ball valve and the plunger is rotated slightly during the lock down, the lowermost cylindrical portion of the plunger is centered on the ball and held against rotation by the resilient legs and a trio of guiding projections arranged in the lower end of the pump chamber about the cylindrical portion. Consequently, the legs have a tendency to wind up torsionally as well as bow resiliently outwardly to thereby compound the resistance of the plunger to unseating movement by the ball.

Abstract: A one-time use, disposable, plastic-molded locking clip is provided for retaining the depressible plunger of a dispensing pump in a fully extended position during shipment or otherwise. The clip may be snapped onto the plunger after the latter has been fully assembled, yet once installed, the snapped together portions of the clip are not readily detectable nor accessible so that the clip may not be removed without destroying the same by tearing a twist tab therefrom. The generally C-shaped jaws of the clip embrace the plunger immediately below the head thereof in order to block depression, and such jaws forceably interlock with each other into a complete loop so that the clip may be installed upon pumps devoid of structure which would assist in locking the clip in place. Mating hooks of the interlocking components on the jaws are so oriented that the resistive force from the plunger tending to spread apart the embracing jaws of the clip simply tends to tighten the interengagement of the hooks as the jaws pull against each other at their outer ends.

Abstract: When the plunger is fully depressed, radially projecting lugs carried by the plunger adjacent its normally upper end may be received within corresponding notches in a collar through which the plunger reciprocates, whereupon rotation of the plunger in a clockwise direction moves the lugs under overhanging shoulders of the collar so as to prevent extension of the plunger until it is intentionally unlocked from the collar. A total of three lugs are utilized so as to provide three-point, stabilized retention of the plunger in its locked-down condition, and one of the lugs and its corresponding notch is smaller than the other two so that the plunger can be locked only when it is in a certain, predetermined rotative position relative to the collar aligning the down-sized lug and notch. Each of the shoulders is provided with a lower, lug-engaging, inclined surface which bears against its corresponding lug with progressively increasing force for fluid-tight sealing purposes as the plunger is rotated into a fully locked condition, there being abutments associated with the shoulders blocking movement of the lugs beyond positions corresponding to the fully locked and rotated position of the plunger.

Abstract: A trigger sprayer has a nozzle assembly that dispenses a spray of liquid in a fan pattern that is selectively oriented horizontally or vertically. The nozzle assembly includes a nozzle housing and nozzle cap mounted on the nozzle housing, where the nozzle cap is rotatable relative to the nozzle housing to direct a fan spray pattern of liquid from the nozzle cap in both a vertical and horizontal orientation, and prevent the discharge of liquid from the nozzle cap in cap positions between the horizontal and vertical orientations.

Abstract: A manually operated, vertically reciprocating liquid pump dispenser is removably connectable to a bottle containing liquid and simultaneously pumps liquid from the bottle and air from the exterior environment of the dispenser and mixes the liquid with the air to produce a foam that is dispensed from the dispenser. The dispenser includes a closure connector and a rotatable collar on the connector that provides a mechanism for venting the interior of the bottle to the exterior environment of the dispenser while avoiding leakage of the liquid from the bottle, and also incorporate a mechanism for locking the dispenser to prevent unintended pumping of liquid from the bottle.

Abstract: A cap closure that dispenses liquid from a liquid container has a cylindrical base that is removably mounted on the liquid container. A valve spout is mounted on the base for linear reciprocating movement. A valve actuator is mounted on the base for rotation. The spout is movable between closed and opened positions where in the opened position liquid can be dispensed through the spout and in the closed position the liquid is blocked from passing through the spout. The actuator is operatively connected to the spout whereby rotation of the actuator between first and second positions relative to the cap base moves the spout between the respective closed and opened positions of the spout on the base.
