  • Publication number: 20230271206
    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.

  • Publication number: 20220203392
    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.

  • Publication number: 20210276223
    Abstract: A preform can be made from two different materials that do not bond together by a bi-injection process, using the same mold. First an outer preform can be fashioned first, then an inner preform molded through a center hole in the outer preform, and the preforms connected. Inner/outer preform materials can be different, e.g., PET/polyolefin or polyamide, or the same, e.g., PET/PET. To prevent mutual bonding during molding of the second, a non-stick coating can be sprayed on a surface portion of the first preform prior to molding, the second. Manufacturing order can be either outer/inner, or inner/outer, and the non-stick coating sprayed on the inside/outside of the perform first molded.

  • Patent number: 11027296
    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.

  • Patent number: 11027298
    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.
