Abstract: The invention relates to a system (1) for dosed dispensing of a fluid, comprising a contain (2) for the fluid and a dispensing device connected therewith, wherein the container comprises a form-retaining outer container (5) and a flexible inner container (4) connected therewith, wherein a space to be brought into fluid communication with the ambient atmosphere can be developed between the inner and outer containers (5, 4), 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.

Abstract: “Flairosol” dispensing devices are presented. They utilize a combination of Flair® technology, precompression valves and aerosol like pressurization of the dispensed liquid. An exemplary device has a main body comprising a pressure chamber, the latter being provided with a pressure piston and a pressure spring, 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, which serve to prevent backflow. A dome valve can be provided near the outlet channel at the top of the dispensing head, such that once its pressure is exceeded by the liquid, it opens and allows for a spray. Alternatively, in an activated embodiment, the dome valve is locked unless opened by a user.

Abstract: 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.

Abstract: In exemplary embodiments of the present invention, various new generation dispensing devices can be provided. Such devices are vertically aligned, provide greater than 1.0 cc per piston stroke, and can involve a range of sprayer heads and sprayer/foamer systems incorporating such heads. Such novel sprayer heads can include a novel stretched piston, or, for example, the standard separate piston and piston chamber configuration. By using integration of parts, and a novel dome valve, exemplary sprayers are more easily manufactured, and have better operating properties. Finally, pre-compression is such novel valves is supplied by a novel dome valve with binary behavior, and minimal hysteresis.

Abstract: A device for dispensing a medium from a container is presented. In exemplary embodiments of the present invention, an exemplary container has at least one feed opening connectable to the container by means of coupling means, a dispensing conduit manufactured from substantially flexibly deformable material, and a closing means for a substantially air-tight closing of the dispensing conduit therewith. In exemplary embodiments of the present invention methods for the manufacture of such exemplary dispensing devices can include injection molding the coupling means and the dispensing conduit as a perform, and stretching, blowing or any combination of stretching and blowing a portion of the preform so as to obtain a substantially flexibly deformable, thin-walled dispensing conduit.

Abstract: A composite container, comprising a form-retaining outer container and a flexible inner container is presented. The inner container comprises a dispensing opening and can be mounted in a neck of the outer container, and the inner container is further connected to the outer container by an adhesive or weld connection over a portion of its periphery. The adhesive or weld connection can take the form of a ring adhesion or weld extending transversely to a central longitudinal axis of the container, or can cover the entire surface area of a defined portion of the respective inner container and outer container walls, such as, for example, the upper one-half of the container. The adhesion or weld can be substantially permanent, or alternatively, the adhesive or weld connection can be adapted to detach in controlled manner under the influence of pressures occurring in the container.

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.
