A foam dispenser with a pump mechanism that mixes a liquid with air to generate foam. The pump mechanism includes a first stage pump and a second stage pump. The first stage pump delivers the liquid and a first volume of the air through a first foam generator to generate a first foam. The second stage pump delivers the first foam and a second volume of the air through a second foam generator to generate a second foam.

A bag-in-bottle type of a squeeze dispenser comprising a housing, a cap, a flexible bag for containing fluid, and means to equilibrate atmospheric air pressure with air pressure inside the housing is disclosed. Said means include a closable air channel. The closable air channel, and the cap, may each be in an open or a closed position. When the cap is in an open position, the closable air channel is in a closed position, thus substantially locking the air inside the housing in place and allowing for fluid to be dispensed from the flexible bag upon application of pressing force on the sidewalls of the housing. When the cap is in a closed position, the closable air channel is in an open position, allowing for a flow of atmospheric air into, and out of, the dispenser housing and thereby equilibrating the air pressure inside the housing with air pressure of the atmospheric air.

A system for dispensing a personal care fluid, such as a hand soap or the like. The system includes a dispenser and a refill cartridge. The dispenser includes a dispenser body having a refill cavity and a dispenser lid configured to be coupled to the dispenser body. There may be a pump sub-system mounted to the dispenser lid, or alternatively the personal care fluid may be dispensed by squeezing the dispenser and refill cartridge. The refill cartridge is configured for slidable insertion into and removal from the refill cavity of the dispenser body. The personal care fluid system is designed so that a user can readily and easily change out/replace the refill cartridge for use with a common dispenser, dispenser lid, and pump sub-system.

A dry powder spray bottle includes a bottle body. The bottle body includes an outer bottle and an inner bottle, a piston and a one-way air inlet valve are sequentially arranged between the inner bottle and the outer bottle, a powder storage cavity is formed above the piston, and an airbag structure is formed between the one-way air inlet valve and the outer bottle. A rotating powder stirring mechanism is provided between the inner bottle and the outer bottle. A one-way valve is provided in the powder stirring mechanism, and when the head cap is pressed, the one-way valve opens, and gas in the airbag structure is delivered to the inner bottle through the one-way valve and sprayed out from the head cap together with dry powders, and a sealing mechanism which can close a powder outlet passage is provided between the head cap and the inner bottle.

A wobble plate for a sequentially activated multi-diaphragm foam pump includes three or more wings, a wobble plate shaft, and an aperture located in each of the three or more wings. A first wing is configured to have a first distance from first contact surface of a first pump diaphragm. A second wing is configured to have a second distance from a first contact surface on a second pump diaphragm, and a third wing is configured to have substantially the second distance from a first contact surface on a third pump diaphragm.

Disclosed herein are embodiments of a manually operated liquid dispenser. In any embodiments disclosed herein, the dispenser can include a housing with a volume of space therein, the volume of space having a first end and a second end, a pump sleeve extending into the space of the housing and nearly to a bottom, inside surface of the space, a pump head, a push rod coupled with the pump head and configured to be axially movable within an axial opening extending through the pump sleeve, a passageway extending through at least the pump head and the push rod, the passageway being in fluid communication with the axial opening extending through the pump sleeve and with the volume of space within the housing, and a first valve configured to control a passage of a liquid substance within the volume of space in the housing through a passageway.

A fluid pump includes a press head portion, first and second unidirectional-valves, and extensible sleeve-pipe. Disposed in the press head portion, the first unidirectional-valve allows fluid to flow from its second end to its first end. The extensible sleeve-pipe includes a rebound element and outer and inner pipes which form a capacity-variable storage chamber. The inner pipe has a first end communicating with the first unidirectional-valve and a second end fitted to a first end of the outer pipe. The second unidirectional-valve allows the fluid to flow from its second end to its first end. The first end of the second unidirectional-valve communicates with the second end of the outer pipe. Upon contraction displacement of the inner pipe, the fluid flows from the storage chamber into the discharge passage via first unidirectional-valve. Upon expansion displacement of the inner pipe, the fluid flows into the storage chamber via second unidirectional-valve.

In exemplary embodiments of the present invention, “Flairosol” dispensing devices can be provided. Such devices utilize a combination of Flair® technology, pre-compression valves and aerosol-like pressurization of the dispensed liquid. Such a dispensing device has, for example, a main body comprising a pressure chamber, the latter being provided with a pressure piston and a pressure spring. The device further has a piston and a piston chamber which draws liquid from a container, for example, the inner container of a Flair® bottle, and fills the pressure chamber with that liquid as a user operates a trigger in various compression and release strokes. The piston chamber has both an inlet valve and an outlet valve, which serve to prevent backflow. Liquid exiting the piston chamber under pressure (supplied by, a user pumping the trigger) enters a central vertical channel which is in fluid communication with both the pressure chamber (above the pressure piston) and a dome valve provided near the outlet channel at the top of the dispensing head. The dome valve has a preset pressure, such that once exceeded by the liquid, opens and allows for a spray. If the liquid pressure drops below such preset pressure, the dome valve closes off the outlet channel, which serves to regulate the strength of the flow and preclude leakage. Alternatively, in an activated embodiment, for example, once the liquid is sufficiently pressurized, it can be dispensed by a user allowing the dome valve to open by pressing on an activation button that removes a dome lock.
