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.

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).

A spray device includes a bottle portion, a sleeve, and an engine. The engine includes a spring that when compressed pressurizes a chamber containing a dispensable amount of fluid from the bottle portion. The sleeve and the engine are configured to be torquable onto the bottle without compressing the spring. Rotation of the sleeve relative to the bottle by a user pressurizes a chamber containing fluid from the bottle. Auditory and/or tactile feedback is provided to the user during rotation of the sleeve thereby allowing the user to select an amount of the fluid to be dispensed. The engine includes a main spring that when compressed pressurizes a chamber containing a dispensable amount of fluid from the bottle. The spring is enclosed between a cup and a cap, which have been fused together.

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.

Aerosol-free spray devices are provided. According to some embodiments, an aerosol-free spray device includes a piston operable within a piston chamber and coupled to a vacuum plunger operable within a vacuum chamber. Each component, including valves, of the aerosol-free spray device is composed of recyclable material of the same resin identification number. With the entire device made of material of the same resin identification number, the spray device is entirely and easily recyclable.

A holding device for a spray container that includes a body, a nozzle portion on a top of the body, and a groove formed between the body and the nozzle portion, the holding device including a base, which is constructed to be placed on a top of the body around the nozzle portion; a pressing part that is connected to a first portion of the base and extends over the nozzle portion, wherein an end of the pressing part includes a first interlocking part; and a first supporting bar which is connected to a second portion of the base, wherein a second interlocking part is formed on or about a top of the first supporting bar and a first protrusion is inwardly formed on or about a bottom of the first supporting bar to detachably couple with the groove.

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.

Dispensing devices can include buffers. This obviates the need for continually pumping the device to dispense spray or foam. A buffer can be spring loaded, spring loaded combination, elastomeric or gas, and can be in line or adjacent to a piston chamber. Such sprayers and foamers can be mounted upside down. With a buffer, a piston chamber can deliver a greater amount of liquid per unit time than can be dispensed through the nozzle(s). The fraction of liquid that cannot be dispensed can be sent to the buffer for dispensing after the piston downstroke has completed. Volume of the piston chamber and buffer, pressure response of the buffer, throughput of the nozzle, and the minimum opening pressure of the outlet valve can be arranged to restrict the outlet pressures of liquid droplets exiting the nozzle within a defined range.

A holding device is used to maintaining a push button of a spray container to be pressed to release contents without continuous press by an operator. The holding device for a spray container comprises a supporting part which is placed around the push button, an adjusting part having a pillar-shaped portion standing on the supporting part and a diving board-shaped portion connected to the pillar-shaped portion and extending over a top of the push button, on a top of the diving board-shaped portion having a recess; and an auxiliary part being pillar-shaped and standing on the supporting part, having a protrusion toward the adjusting part to be engaged with the recess.
