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 fragrance product is disclosed including a container containing liquid fragrance and a dispenser assembly for dispensing the liquid fragrance including a transport assembly and a tube connected to the transport assembly and extending into the liquid fragrance. The tube and the liquid fragrance each have a refractive index, and the difference between the refractive index of the tube and the liquid fragrance is not greater than about 0.04.

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 manually operated sprayer for a container of liquid to be sprayed includes variable volume pump means having liquid inlet and outlet means for discharging the contents of the container. The sprayer further includes a control module having product and vent valves reciprocably disposed therein, the product and vent valves being simultaneously reciprocable by means of the manual actuator between valve open and valve closed positions. In the valve open position, the product and vent valves respectively prevent flow of product and air respectively into the liquid inlet means and into a vent passage in communication between atmosphere and an interior of the container, and in the vent closed position, the product and vent valves respectively enable flow of product and air respectively into the liquid inlet means and into the vent passage.

Abstract: A hand operated liquid dispenser has a simplified, in-line construction that reduces the number of component parts of the dispenser and thereby reduces the dispenser's manufacturing costs. The in-line construction of the liquid dispenser coaxially aligns a liquid discharge orifice, a liquid discharge passage, and a pump chamber of the dispenser. The construction provides a compact liquid dispenser that can be easily held in one hand by a user and manipulated by the fingers of the user's hand to pump liquid from a bottle attached to the liquid dispenser and dispense the liquid in a variety of different discharge patterns.

Abstract: A manual pump dispenser includes a plunger head reciprocable between pressure and return strokes, and a pump body having an inlet valve for inletting of liquid product during each of the return strokes. A discharge valve assembly is fitted to a spout for permitting selective outletting of liquid product through the spout during each of the pressure strokes. The spout includes a bore having a predetermined diameter, with a unitary valve disposed substantially within the bore. The unitary valve is made of a material for permitting predetermined axial, or axial and radial expansion thereof under pressure from liquid product during each of the pressure strokes for thereby allowing liquid product to be discharged through a slitted opening in the unitary valve, and enabling rapid contraction thereof against a valve seat to prevent liquid product from being discharged through the slitted opening.

Abstract: In one embodiment of a dispensing system for connecting a remote power sprayer to a container of liquid, a flexible delivery tube includes one end non-removably connected to a remote retainer and the other end non-removably connected to a connector hose. The remote retainer and connector hose each include strain relief elements which respectively include a retainer adaptor and a connector adaptor for relieving the connection strain between the tube, the remote retainer and connector hose, as the power sprayer is being pulled and maneuvered during use. In a second embodiment, the flexible delivery tube includes one end non-removably connected to a remote retainer and the other end disposed freely in a container, but plugged onto a connector hose and including a spring weight slidably disposed thereon.

Abstract: A sprayer head assembly comprises a sprayer head and a valve for controlling the flow of fluid through the assembly. The sprayer head comprises a chemical passage, a carrier fluid passage and a vent passage. A generally cylindrical bore is in communication with the chemical, vent carrier fluid passages. The valve is moveably positioned within the bore. The valve is moveable between a first position and a second position. The valve comprises a first passage and a chemical inlet passage that is in communication with the first passage. In the first position, the valve blocks the vent, chemical and carrier fluid passages. In the second position, the first passage is configured to be in communication with the carrier fluid passage while the chemical fluid passage is in communication with the chemical inlet passage. The valve defines a suction generating recess positioned within the first passage.

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.

Abstract: A hose-end sprayer assembly connectable to at least one container of product to be dispensed has an elongated housing for a venturi tube assembly rotatable about its central axis and devised to selectively open and close a product inlet opening as well as its associated vent valve, an independently controllable liquid carrier valve being provided for opening and closing the carrier liquid flow through the venturi tube duct in the venturi tube assembly can be devised for opening and closing inlet product inlet openings of separately stored chemical products sequentially or simultaneously.

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.
