ABSTRACT:
A device for dispensing a predetermined quantity of the contents of a container, including a container for the contents. The container has a base to locate the container in an upright position and has a generally upwardly facing opening. The device also includes a chamber on the container which has a first end in communication with the opening and a second end open to dispense contents from the chamber when the container is moved from an upright position to cause the contents to enter the chamber. Also, the device is provided with a valve spool mounted inside the chamber for regulating the quantity of contents flowing through the opening into the chamber. The valve spool includes a piston for leading the flow of contents from the first end of the chamber to the second end. The valve spool further includes a valve for closing the opening at the first end after the chamber receives the predetermined quantity.
