Abstract: Serrations on the upper end of the pump body are disposed for interlocking engagement with depending portions of the pump collar so that when the plunger is rotated in a counterclockwise direction to unlock the same from the collar in preparation for reciprocal operation, the collar is held securely by the body against rotation to assure unlocking. The serrations take the form of a plurality of equally circumferentially spaced ramps which are inclined in the direction of locking rotation of the plunger to thereby permit the collar to yieldably override the serrations when the locked plunger and collar are rotated as a unit in the locking direction relative to the body to orient a spout of the plunger in a desired location for factory packaging efficiency.

Abstract: The pump is clamped to the top wall of a container closure by a pair of opposed, upper and lower clamping surfaces on the pump body which position the body to project down into the container. The lower clamping surface takes the form of a circular flange which is integral with the pump body and which is itself normally clamped between the top wall of the closure and the upper edge of the neck of the container when the neck is only slightly larger than the pump body, thereby preventing rotation of the body when the pump plunger is rotated to either lock or unlock the same from a fully depressed, stored position. When the pump is used on a large closure having a wide neck whose upper edge therefore fails to clamp against the pump flange, the pump body will nonetheless be held immobile by a series of flat surfaces therearound which matingly interlock with complimentally configured flat edges in the closure opening through which the pump body extends.

Abstract: A trigger sprayer has a housing, a piston bore within the housing, and a piston reciprocally mounted within the piston bore. The housing further includes a flow passage through which liquid passes from a passage inlet to a passage outlet. An actuator is operable to reciprocate the piston within the piston bore between a vacuum stroke creating reduced pressure in the piston bore and a compression stroke creating increased pressure in the piston bore. A valve assembly within the flow passage controls the flow of liquid through the flow passage upon operation of the actuator. The valve assembly further comprises a check valve and a priming valve. The sprayer has a closure for mounting the sprayer to a container. The valve seat for the check valve is in a component formed separately from and operatively connected to the housing.

The housing further includes a flow passage through which liquid passes from a passage inlet to a passage outlet. An actuator is operable to reciprocate the piston within the piston bore between a vacuum stroke creating reduced pressure in the piston bore and a compression stroke creating increased pressure in the piston bore. A valve unit within the flow passage controls the flow of liquid through the flow passage upon operation of the actuator. The valve unit further comprises a check valve and priming valve. The check valve is shaped in a frusto-conical manner and is assembled into the check valve seat which is not part of the housing but is a separate component. The sprayer has a free spinning threaded type closure for mounting the sprayer to a container, the closure formed separately from and secured to said housing.

Abstract: A manually operated liquid foaming dispenser is attached to the top of a container of liquid and is manually reciprocated to dispense the liquid from the container as a foam. The dispenser includes a liquid pump chamber and an air pump chamber that respectively pump liquid and air under pressure to a discharge passage of the pump where the liquid and air are mixed, generating the foam dispensed from the dispenser. The air pump chamber has a tube valve controlling the discharge of air from the air pump to the discharge passage, and the air pump chamber is charged with air by opening the air pump chamber to the exterior environment of the dispenser.

Abstract: A manually operated trigger sprayer is constructed with a reduced number of parts and in a novel manner in which the conventional metal coil spring is replaced with a pair of plastic bowed springs that are integral with the piston rod and the pump piston is connected to the piston rod by a pivoting connection that prevents radial force components acting on the piston rod from the springs from being transferred to the pump piston.

Abstract: A trigger sprayer has a one piece valve member that includes both an inlet valve element and an outlet valve element. The one piece valve member replaces the separate liquid inlet valve and liquid outlet valve of a conventional trigger sprayer, and thereby provides a more simplified construction for the trigger sprayer and a fewer number of component parts in the trigger sprayer.

Abstract: An indexing nozzle assembly for a trigger sprayer is comprised of a nozzle base that is attachable to a sprayer housing of the trigger sprayer, a cap that is mounted for rotation on the nozzle base, and a foaming tube that is mounted for linear reciprocating movement on the cap. Rotation of the cap on the nozzle base changes liquid discharge from the trigger sprayer between an off condition and at least a spray condition. In the spray condition of the nozzle cap, the foaming tube can be manually pulled and extended from the nozzle cap. With the foaming tube extended from the nozzle cap, the liquid discharge from the nozzle assembly in a spray pattern comes into contact with an interior surface of the tube and generates a foam discharge from the nozzle assembly.

Abstract: A manually operated vertically reciprocated pump dispenser has a simplified construction with two separate pumps that pump two separate liquids from a container and keep the two separate liquids separated from each other as they are pumped through the dispenser, mixing the liquids for the first time in a discharge passage of the dispenser just prior to the mixed liquids being discharged from the dispenser. The dispenser has a rotatable sleeve that covers the two pumps and is rotated to lock and unlock a dispenser head that operates the two pumps.

Abstract: A manually operated trigger sprayer includes U-shaped springs that bias the trigger sprayer trigger away from the trigger sprayer pump chamber, where the U-shaped springs are connected to a piston rod by a snap-fit connection. The connection includes a compressible forward end of the piston rod that is pressed through an opening on the forward end of the spring to connect the piston rod to the spring. The rearward end of the spring is connected to the sprayer housing by a curved surface that engages around an exterior surface of the pump chamber.
