    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. 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.

    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: 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.

    Abstract: A “Flair® Sprayer” can be provided with no dip tube, and can be capable of being used in any orientation, including upside down. Using a unique valving system, where the product delivery circuit is a closed system, a Flair Sprayer can pump out any gas in a bottle's headspace and the product/liquid always reaches the pump intake, even with no dip tube. A dispensing device can have separate product and re-venting/propellant circuits, isolated one from the other, allowing for longer life and freshness of the product. Air or other displacement media can be used for various ancillary functions, all the while remaining isolated from the product, and the dispensing of the product can be adeptly controlled by pressure differentials (under-pressures and overpressures).

    Abstract: A method for dosed dispensing of a pressurized liquid is presented. In exemplary embodiments of the present invention, the method includes dispensing a liquid in a container via a dispensing opening into a dispensing space, where a difference in pressure between the container and the dispensing space is equalized in stages by using an intermediate dosing chamber. In a first stage the pressure is equalized between the container and the dosing chamber, then a quantity of the liquid is dispensed from the container into the dosing chamber, maintaining the pressure equivalence between the container and the dosing chamber by pressure communication between them. Next, the dosing chamber is isolated both as to gaseous and liquid connection from the container. Then, in a second stage the pressure is equalized between the dosing chamber and the dispensing space, and the quantity of liquid in the dosing chamber is dispensed into the dispensing space as the pressure between the dosing chamber and the dispensing space is maintained equal. The method further includes providing the liquid in a first inner container of the container, and introducing a pressure equalizing medium into a second inner container, where the first and second inner containers adjoin each other at least with a deformable and/or displaceable side. The invention also relates to a dispensing device arranged to perform, inter alia, the disclosed method. In exemplary embodiments of the present invention a dispensing device can comprise a self-contained carbonated beverage dispenser that can be stored in a consumer's refrigerator, or can, for example, be self cooling.
