A device for assisting in the dispensing of liquid comprising a shaft having a substantially hollow passage therein, a first cap disposed on a first end of the shaft, a second cap disposed on a second end of the shaft, the second cap having an opening therein which is substantially aligned with the hollow passage, and, a spider guide disposed between the second cap and the shaft, wherein the shaft has at least one hole therein disposed at a position closer to the first end of the shaft than the second end of the shaft. The device is preferably inserted into a container which holds liquid to be dispensed. The device provide a venting and dispensing controlling system whereby defined quantities of liquid can be dispensed from the container quickly and efficiently.
The present invention is a narrow neck dosage device for dispensing a predetermined quantity of product. An insert is installed in a narrow neck of a container with a bottom disk protruding into the body of the container and a top device within the neck of the container. The bottom disk initially hangs within the container body, while the top device rests on a divider that separates the neck from the container body. The top device can be upward angled blades, angled blades or a circular disc. A shaft connects the top devices and the bottom disk. The shaft also can have multiple configurations, such as spiral, flat helix, or random kinks. The shaft spins, rocks or oscillates and passes through a hole in the center of the divider. The divider has pre-sized holes that allow product to pass through. When the container is tipped into a dispensing position, fluid pressure moves the insert up the neck of the container until the bottom disk reaches the divider and seals the neck off from the body of the container. The container is returned to an upright position after dispensing and the weight of the insert spins, rocks or oscillates the insert downward into the starting position.
