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.

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. In exemplary embodiments of the present invention, such novel sprayers and foamers can be mounted upside down, in various 'Flairomop' devices, used to clean floors or the like. When using a buffer, a piston chamber can be designed to deliver greater amount of liquid per unit time than can be possibly dispensed through the nozzle or nozzles. The fraction of liquid that cannot be sent through the nozzle(s), due to their inherent restriction, can thus be sent to the buffer for dispensing after the piston downstroke has been completed. A volume of the piston chamber, a volume of the buffer, a pressure response of the buffer, the 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.

Dispenser

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.

Gas-filled resilient body and use thereof

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.

Spraying head for dosing and dispensing device

The invention relates to a device () for dispensing a liquid from a container (C), comprising a pump () having a suction side (S) that is adapted to be brought into fluid communication with the container (C), a spray nozzle () in fluid communication with a pressure side (P) of the pump () through an outlet channel (), a pre-compression valve () arranged in the outlet channel (), and a gas buffer () in fluid communication with the pressure side (P) of the pump () and with the spray nozzle (). The gas buffer () may comprise a buffer chamber () in which a gas-filled resiliently deformable body () is arranged, and the gas buffer () may extend from the pressure side (P) of the pump () in a different direction than the outlet channel (). 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 () 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:&#x2014;drawing the liquid from a container (C) and pressurizing the liquid by actuating a pump (), wherein the container (C) and the pump () form part of a dispensing system;&#x2014;guiding a part of the pressurized liquid to a spray nozzle () of the dispensing system;&#x2014;spraying the liquid from the nozzle ();&#x2014;guiding another part of the pressurized liquid to a gas buffer () for temporary storage; and&#x2014;spraying the stored liquid from the nozzle () when the pump () is not being actuated; wherein the pressurized liquid is guided from the pump () to the spray nozzle () in a different direction than from the pump () to the gas buffer ().

The invention relates to a system () for dosed dispensing of a fluid, comprising a contain () 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. The invention further relates to a method of manufacturing a system for dosed dispensing of a fluid.

System for dosed dispensing of a fluid and method of manufacturing

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.

Provided is a liquid dispensing device that includes: a piston chamber; a piston that is moveable within the piston chamber to pressurize a liquid to be dispensed; a nozzle with a defined throughput for dispensing the liquid; an outlet valve having a defined minimum opening pressure arranged between the piston chamber and the nozzle; and a prime valve for priming the device, where the prime valve may be mechanically operable and may be arranged on or in the piston.
