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: 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.

Abstract: In embodiments, aerosol-type devices are provided. The devices have a main body comprising a pressure chamber, with pressure piston and pressure spring, and a piston chamber which draws liquid from a reservoir and fills the pressure chamber as a user performs compression and release strokes. The piston chamber has both inlet and outlet valves. In a dispensing head a valve is provided to regulate the flow strength and preclude leakage. Once the liquid is sufficiently pressurized, it is dispensed by a user opening an activation valve, and spray can be abruptly stopped by closing the activation valve. In alternate embodiments, without an activation valve, once the liquid is pressurized, continuous spray occurs until the pressure chamber is fully emptied. Pumping the trigger before the pressure chamber is fully emptied achieves continuous spray. When the input volume is greater than the volume of the pressure chamber volume, continuous spray with fewer pumping strokes occurs.

Abstract: The invention relates to a device (1) for dispensing a liquid from a container (C), comprising a pump (2) having a suction side (S) that is adapted to be brought into fluid communication with the container (C), a spray nozzle (3) in fluid communication with a pressure side (P) of the pump (2) through an outlet channel (4), a pre-compression valve (5) arranged in the outlet channel (4), and a gas buffer (9) in fluid communication with the pressure side (P) of the pump (2) and with the spray nozzle (3). The gas buffer (9) may comprise a buffer chamber (10) in which a gas-filled resiliently deformable body (11) is arranged, and the gas buffer (9) may extend from the pressure side (P) of the pump (2) in a different direction than the outlet channel (4). The invention further relates to a system for dispensing a liquid, comprising a container (C) that is filled with the liquid and a dispensing device (1) of the type described above connected to the container (C). And the invention relates to a method for dispensing a liquid, comprising the steps of: —drawing the liquid from a container (C) and pressurizing the liquid by actuating a pump (2), wherein the container (C) and the pump (2) form part of a dispensing system; —guiding a part of the pressurized liquid to a spray nozzle (3) of the dispensing system; —spraying the liquid from the nozzle (3); —guiding another part of the pressurized liquid to a gas buffer (9) for temporary storage; and —spraying the stored liquid from the nozzle (3) when the pump (2) is not being actuated; wherein the pressurized liquid is guided from the pump (2) to the spray nozzle (3) in a different direction than from the pump (2) to the gas buffer (9).

Abstract: A system for dispensing liquid foam, in particular a direct foam cleaning product, comprises a container for the liquid and a dispensing apparatus connected to the container. The dispensing apparatus comprises a pump comprising a pump chamber in fluid communication with the container and a piston arranged in the pump chamber, the piston and pump chamber being movable with respect to one another. An outlet channel connects the pump chamber to a nozzle. A pre-compression valve is arranged between the outlet channel and the nozzle; and a buffer comprising a buffer chamber is connected to the outlet channel. The buffer chamber includes a compressible variator arranged therein for varying the usable volume of the buffer chamber; wherein the nozzle, the buffer and the pump are configured and dimensioned such that the foam is dispensed in a predetermined spray pattern.
