Abstract: A dispensing system includes a pump mechanism that has a liquid chamber, a liquid piston for delivering fluid to a mixing chamber, and a valve component biased to close the outlet from the liquid chamber. The pump mechanism also has an air chamber, and an air piston for delivering air to the mixing chamber. A bore allows passage of a mixture of the air and the liquid from the mixing chamber to a dispensing tube. A pump actuator moves the air piston and the liquid piston to propel a dose of the mixture of the air and the liquid through the bore and into the dispensing tube and to collapse a draw-back chamber. The draw-back chamber expands to draw the mixture of the air and the liquid from the dispensing tube into the draw-back chamber. The valve component is biased to close the first outlet before the draw-back chamber expands.

Abstract: A double-acting or lift and force pump for ejecting a product from a container, with a housing in which a piston with an axial bore is axially slidable and sealed by a first housing portion, with a hollow piston rod which extends the axial bore of the piston and is slidable in an opening of a piston rod has at its free end a tightly fastened actuating head, wherein, when the actuating head is actuated, the piston builds up a pressure against the force of a restoring spring in a pressure chamber of the housing, wherein an outlet duct connected to the bore extends through the actuating head and through a check valve up to an ejection opening for the product, and with at least one opening in a second housing portion between the first housing portion and the closing cap. The piston in the non-actuated state thereof under the restoring spring force leaves a passage between the pressure chamber and the at least one opening in the second housing portion, wherein a section of the outlet duct adjacent the check valve has between two cup-shaped sleeves of the actuating head, which are laterally tightly placed against each other, a groove formed on the outer side of the inner sleeve, wherein the groove is covered by the outer sleeve and extends up to an expansion chamber formed in front of the outlet opening formed in the bottom of the outer sleeve, and wherein a germ-killing and bacteria-killing medium is arranged in the expansion chamber, wherein the medium permits flow of the liquid to the outlet opening, wherein the dispensing stroke volume of the piston corresponds to the volume of the drop of the liquid, and wherein the width of the outlet opening prevents a spraying effect.

Abstract: A manually actuated pump dispenser has a water seal for maintaining the container vent ports sealed closed during pumping until at or near the end of the pressure stroke whereupon a vent path through which only air is permitted travel into the container, is open as the path is shielded against water entering the vent path when pumping in a wet environment as when dispensing hair shampoo or hair conditioner. In a plunger lock-down position of shipping and storage, leakage of product through the vent ports is substantially avoided during a superatmospheric condition within the container.

Abstract: A hand pump for pumping out fluid from a reservoir, comprising a pump body, a faucet, a driving mechanism and a sealing arrangement. The pump body has at a side a connector defining a receptacle radially extending into a cavity of the pump body. The driving mechanism includes an axle inserted in the receptacle of the connector, a sealing sleeve mounted around the axle, a coupling cap axially secured to the sealing sleeve, and a L-shaped handle. The handle having at one end inserted through the coupling cap and the axle, and at the other hand extending outside the coupling cap. Operation of the handle in cyclically up and down motion drives the axle to rotate, which causes a piston in the cavity to move upward and downward so as to suck the fluid into the faucet. The sealing arrangement has at least three O-rings disposed among the parts of the driving mechanism to provide an effective seal between the driving mechanism and the pump body.
