The present invention relates to a powder dispensing container. When a button is pressed, a piston formed in close contact with the inner wall of an external housing is lowered so that air in the external housing is moved to an inner housing and discharges powder flowing into the internal housing, thus it is possible to always dispense the powder consistently regardless of the amount of the powder stored in a container body.

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.

A pump assembly cap includes an accumulator reservoir configured for fluid communication with a container through a one-way inlet valve. An actuator including a dispensing passage having a dispensing orifice. A delivery path extended from the one-way inlet valve, through the accumulator reservoir, the one-way outlet valve, and to the dispensing orifice. The delivery path includes a sealed configuration and an opened configuration. In the sealed configuration, the actuator is in a ready position and the accumulator reservoir includes a first volume, the one-way outlet valve hermetically seals the accumulator reservoir, and the one-way inlet valve is closed. In the opened configuration, the actuator is moved to a dispensing position and the accumulator reservoir includes a second volume less than the first volume, the hermetic seal of the one-way outlet is open, and the one-way inlet valve is closed.

Dispensing devices are provided. Such devices utilize a combination of Flair? technology, pre-compression valves and aerosol-like pressurization of the dispensed liquid. An example 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 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. Liquid exiting the piston chamber under pressure enters a central vertical channel which is in fluid communication with both the pressure chamber and a dome valve, with pre-defined opening pressure, provided near the outlet channel at the top of the dispensing head.

A method for assembling a fluid product dispensing pump, including providing a piston (1) secured to an actuation rod (2); a pump body (3) having a pump chamber (5); a sleeve (50), an outlet valve element (39) an inlet valve element (10) which slides in a sleeve (9) of the pump body having a reduced diameter; and a spring (20). The method includes fixing the outlet valve element in the piston; inserting the piston and the outlet valve element into the sleeve; inserting from the top the spring and the inlet valve element into said sleeve; and inserting from the top the sleeve into the pump body.

A pump having a piston (1) sliding in a body (3) having a chamber (5) between an inlet valve (11) and an outlet valve (12), an outlet valve element sliding during actuation in the chamber (5), and a passage (40) wherein, at end of actuation, the outlet valve element (39) cooperates in a non-sealing manner with the passage to open the outlet valve. The inlet valve has an inlet valve element (10) that slides after closure in a sleeve (9) with reduced diameter and a spring (20) bearing on the inlet valve element and on a bottom of the sleeve. The spring (20) returns the piston into its rest position. The sleeve (9) has an inner diameter of less than 4.2 mm. The spring (20) has a force of at least 20 N, so that the pump delivers the fluid product at a pressure (P) of at least 15 bars.
