  • Patent number: 6689279
    Abstract: A device used in separating flowing substances and can be placed inside the top of a dispenser. The device separates high viscosity liquid from a low viscosity liquid. The device is comprised of a smooth conical funnel piece inverted into the dispenser containing the substance. The top of the device is flat and the top rim of the device extends horizontal across the dispenser's neck opening. Rim of the device may be adjusted for size by applying pressure at a break point and snap off excess in the flat portion of the device's rim. Device can be separately manufactured or molded with the container as part of the dispenser's top aperture. It can also be molded with the dispensers cover. When the container is inverted, the lighter weight viscosity liquid is retained in the area around the inverted nozzle of the device. The thicker high viscosity liquid can now be discharged from the opening of the dispenser by applying pressure.
