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 fluid dispensing apparatus includes a fluid reservoir and a dispensing assembly. The dispensing assembly includes a housing and a deformable member that define a metering chamber that is configured to receive a predetermined volume of fluid from the fluid reservoir. The deformable member is deformed from a rest position to an eject position and the deformation causes the volume of the metering chamber to change which results in a change in fluid pressure within the metering chamber. An increase in the fluid pressure within metering chamber causes a predetermined volume of fluid within the metering chamber to be ejected and a decrease in the fluid pressure within the metering chamber causes fluid to be drawn into the metering chamber from the reservoir.

Flairosol dispensing devices are presented. They utilize a combination of Flair technology, precompression valves and aerosol like pressurization of the dispensed liquid. An exemplary device has a main body comprising a pressure chamber, the latter being provided with a pressure piston and a pressure spring, 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, which serve to prevent backflow. A dome valve can be provided near the outlet channel at the top of the dispensing head, such that once its pressure is exceeded by the liquid, it opens and allows for a spray. Alternatively, in an activated embodiment, the dome valve is locked unless opened by a user.

A discharging device for liquids. The invention relates to a discharging device for liquids, more particularly for pharmaceutical liquids, comprising a delivery device (10), a liquid storage receptical (20) communicating with an input (10a) of the delivery device for storage of the liquid (30), and a discharge orifice (12) which communicates with an outlet (10b) of said delivery device, and the liquid storage receptical (20) is at least in part in the form of a dimensionally flexible liquid-containing bag (20) and the liquid storage receptical (20) is disposed in a buffer chamber of constant volume (42). To prevent air from escaping from the buffer chamber (42), provision is made for the buffer chamber to be sealed by a protective housing from the environment (1) in a gas-tight manner, for the buffer chamber to communicate with the environment through at least one capillary passageway for the purpose of pressure compensation, or for the buffer chamber (42) to communicate with the environment (1) via a balancing passageway for the purpose of pressure compensation, while a valve (70) which opens in dependence on the pressure differential is disposed in this balancing passageway.

The present invention is directed to airless storage and dispensing systems that include a pump or dispensing package pre-filled with a topical semi-solid imiquimod pharmaceutical formulation (pump systems) and methods for storing and dispensing from the pump systems a plurality of precisely measured and uniform unit doses of a topical semi-solid imiquimod pharmaceutical formulation, and more particularly to pump systems, pre-filled with a topical imiquimod pharmaceutical cream and methods for delivering multiple precisely measured unit doses of a topical imiquimod pharmaceutical cream, and methods for using a controlled delivery pump system to store and dispense a plurality of consistent and precisely measured unit doses of a topical imiquimod pharmaceutical cream for use in topically treating a dermal and mucosal-associated condition, such as, external genital warts and/or perianal warts (EGWs), actinic keratosis or actinic keratoses (AK or AKs) and superficial basal cell carcinoma (sBCC).

A reservoir for a nebulizer, and a nebulizer with a reservoir in which, to avoid undesirable rises in pressure, a fluid chamber of the reservoir is pre-collapsed and filled with an initial amount of fluid which is less than the maximum volume of the fluid chamber. Preferably, before being filled, the fluid chamber is compressed and/or expanded by means of gas to a defined volume which is less than the maximum volume of the fluid chamber.

In exemplary embodiments of the present invention, Flair based aerosol-type 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 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 reservoir and fills the pressure chamber with that liquid as a user operates the trigger in various compression and release strokes. The piston chamber has both an inlet valve and an outlet valve. In a dispensing head a valve is provided to regulate the strength of the flow and preclude leakage. Once the liquid is sufficiently pressurized, it can be dispensed by a user opening an activation valve, such as by pressing on an activation button, and spray can be abruptly stopped by a user ceasing to push on such button. Or, for example, in alternate embodiments without an activation button, once the liquid is sufficiently pressurized, continuous spray occurs until the pressure chamber is emptied. By repeatedly pumping the trigger before the pressure chamber is fully emptied, continuous spray can be achieved. By designing the input volume to be amply greater than the volume of the pressure chamber, continuous spray with fewer pumping strokes can be implemented.
