Abstract: A refillable perfume atomizer apparatus is described, capable of refill without requiring pouring or exposure of an interior of the liquid storage chamber to the external atmosphere. The perfume atomizer includes an internal pump that creates a negative air pressure within the sealed liquid storage container so that refill liquid is drawn into the liquid storage chamber when the perfume atomizer dispenser is engaged to a refill reservoir container.

Abstract: A liquid sprayer apparatus includes a multi-chamber spray mechanism, with at least one chamber being adapted to accumulate pressurized fluid for dispensation over an extended time period. The liquid sprayer apparatus is capable of emitting a liquid spray over a period of time that is substantially greater than a manual pump action applied to the trigger.

Abstract: A pump dispenser is arranged for dispensing solidous material under a manually-developed pressure, with the dispenser being capable of pumping and mechanically agitating the solidous material in a storage container. The resultant dispensed solidous fluid is provided with more consistent suspended solid concentrations with greater solid particle distribution homogeneity.

Abstract: A re-fillable liquid spray dispenser useful as a fragrance atomizer includes a re-filling valve apparatus that is cooperative with a discharge nozzle of a liquid reservoir. A main chamber into which liquid may be filled in the spray dispenser is cyclically vented in unison with liquid injection through the re-filling valve apparatus. In this way, the liquid spray dispenser is accurately and efficiently vented during a liquid filling operation.

Abstract: A liquid foaming dispenser includes multiple valve mechanisms for regulating the inflow and mixture of air and liquid to create a foamable preparation. A gasket incorporating a double-valve structure is employed to regulate air inflow from the external environment, and air delivery to the liquid in preparation for foaming. The valve-regulated foaming dispenser securely and precisely blends the air and liquid for consistent foaming results.

Abstract: A foam pump includes a pump body, a large piston, large piston rod, a small piston, a small piston rod, a over cap and a foaming mesh. The large piston rod is equipped with a one-way valve connected with an air cavity to enable one-way air inlet from the air cavity to a gas-liquid mixing chamber. The mixed air and liquid forms a dischargeable foam.

Abstract: A kind of foam spray gun, comprising a gun body, a nozzle, a trigger, a one-way liquid inlet mechanism, a piston rod, a piston, a resetting piece, a one-way valve and 2 foaming screen meshes, said gun body being provided with a foam generating channel, said piston sleeve being mounted on the inner side of said trigger and moving inward under the driving force of said trigger and engaged with said gun body, said piston being mounted on inner cavity of said piston sleeve and moving together with said piston sleeve and engaged with said gun body to form the first cavity and the second cavity, said one-way valve and foaming screen meshes being mounted inside the foam generating channel of said gun body.

Abstract: A foam pump, comprising a pump body (1), a big cover (2), a big piston (3), a small piston (4), a piston rod (5), a head cap (6) and a foam screen (7), featured by that: said pump body (1) is at the upper part, said big cover (2) is at the lower part, said pump body (1) being integrated with said big cover (2), said head cap (6) being integrated with the lower big piston (3); a sealing ring (9) of elastic materials being provided between said big piston (3) and the inner wall of said pump body (1) for tight engagement, which forms an one-way valve structure, which makes the pump body and the big cover integrated, thus the air cavity can be enlarged, the working pressure of the foam pump can be improved with the big cover of the same size, and the foaming effect of the foam pump can be enhanced; said head cap being integrated with said big piston, a sealing ring is provided between said big piston and the inside wall of the pump body, which simplifies the structure of the big piston and makes the internal stru

Abstract: A foam pump consisting of a pump body, a large piston, large piston rod, a small piston, a small piston rod, a over cap and a foaming mesh, which is featured by that said large piston rod is equipped with a one-way valve connected with an air cavity of said large piston and that said one-way valve adopts sleeve-shaped valve plate made of elastic materials mounted on the fixing base on the large piston rod with a stepped surface and that the upper part of said valve plate adopts conical sealing surface with increasing diameter for sealing together with the connecting hole on said large piston rod, said connecting hole connecting a gas-and-liquid mixing cavity in the large piston rod and said air cavity of said large piston.
