Abstract
The present invention is a self-measuring container that dispenses only a specific amount of fluid each time fluid is poured from the container. This container has a storage chamber where the fluid initially resides and a measuring/dispensing chamber, below the storage chamber, where the specific amount of the fluid that will be dispensed during the next pouring operation resides. An aperture at one end of the container connects the storage and dispensing chambers. This aperture permits the fluid in the storage chamber to flow into the dispensing chamber. The container dispenses the fluid through an exit channel that extends from the dispensing chamber to the top of the container. The storage chamber bottom serves to separate the storage and dispensing chambers and acts as a barrier during a pouring operation to prevent fluid from flowing from the storage chamber to the dispensing chamber until desired. In another embodiment, the storage and dispensing chamber do not have a common wall, but the dispensing chamber is formed to minimize the draw necessary during the formation process. The measuring chamber may also contain a diaphragm to permit the volume within the chamber to be adj…
