Abstract: 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.

Abstract: A dispensing system includes a motor driven air pump having an air inlet and an air outlet, and a dispensing device. The dispensing device is releasably connected to the air pump. The dispensing device includes an air connector connected to the air outlet of the pump, a mixture outlet, a product inlet, and a product uptake system connected to the air connector, the mixture outlet, and the product inlet. The dispensing system includes a product container for a product to be dispensed. The product container is connected to the product inlet. The product container is integrated in the dispensing device. The product uptake system may include an ejector for sucking product from the container and/or a container air inlet for pressurizing the container.

Abstract: In exemplary embodiments of the present invention, various novel dispensing devices can be provided. Such devices can involve a range of sprayer heads and sprayer/foamer systems incorporating such heads. Novel sprayer/foamer heads can include buffers of various types. By using a buffer, a user need not continually be pumping the device in order for the device to be spraying or foaming. In exemplary embodiments of the present invention, such a buffer can be spring loaded, spring loaded combination, elastomeric or gas. In exemplary embodiments of the present invention, the buffer can be in line or adjacent to a piston chamber. If adjacent, it can be connected to the piston chamber with a one way valve, to provide for spray after a downstroke of the piston has been completed, or without, to allow spraying to cease once a user releases the trigger or other actuator.

Abstract: A gas-filled resilient body and uses thereof are described. The gas-filled resilient body may be used as a valve member, as a spring or as a gas-propelled dispenser.

Abstract: A liquid dispensing system includes at least one container for storing the liquid to be dispensed, the at least one container having a neck defining a fill opening for the liquid. The system includes a liquid dispensing device releasably connectable to the at least one container, an exchangeable cartridge for an additive to be mixed with the stored liquid, where the cartridge is accommodated in the neck, and a piercing member for opening the cartridge. The cartridge includes a one-piece hollow body filled with the additive and with a pressurized gas, and the piercing member is arranged to pierce a wall of the hollow body. A method of dispensing a liquid by using the liquid dispensing system, and a cartridge for use in the liquid dispensing system and/or method.

Abstract: The invention relates to a system for dosed dispensing of a fluid, comprising a container for the fluid and a dispensing device connected therewith, wherein the container comprises a form-retaining outer container and a flexible inner container connected therewith, wherein a space to be brought into fluid communication with the ambient atmosphere can be developed between the inner and outer containers, and wherein the dispensing device includes a housing and/or frame of which at least a part is integrally formed with the container.

Abstract: A device for dispensing a material includes a reservoir for the material and an outlet channel connectable thereto. The reservoir has a tubular body partially filled with pressurized gas and partially filled with the material to be dispensed. One end of the tubular body is welded shut and an opposite end is closed by a sealing member extending over at least part of a cross-sectional area of the tubular body. The sealing member is arranged in a sleeve connected to the end of the tubular body opposite the welded end thereof. The sealing member has a pierceable diaphragm and the device may further comprise a piercing member. The sealing member can include a movable valve or can be removably fixed inside the tubular body and the device can include an operating member. The tubular body and the piercing member or operating member, respectively, may be movable towards each other.

Abstract: A device for dispensing a liquid from a container is disclosed, comprising: an engine, comprising a nozzle and a pump for transferring liquid from the container to the nozzle; a trigger, moveable between a first position and a second position, connected to the pump for actuating the pump when brought from the first to the second position, and connecting means, for connecting the engine to the container characterized by a slider with at least one restricting element, slideable between a non-restricting position, in which the trigger is moveable between the first and second position, and a restricting position, in which the at least one restricting element restricts the movement of the trigger between the first and the second position.

Abstract: 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.
