Abstract
The adjustable measuring device has a cylindrical base and a slightly larger cylindrical sleeve which slides upwardly and downwardly on the cylindrical base to form a cup of variable volume. Both cylinders are oblate and preferably are elliptical or oval in cross-section. This allows the height of the device to be reduced, without loss of measuring capacity, and without loss of gripability. Also, the oblate shape forms a natural pour spout. A sealing member having a relatively thin, flexible wiper or flange element forms a seal at the junction between the interior surface of the sleeve and the top of the base member and minimizes leakage of liquid from the cup. A lip on each narrow end of the upper edge of the sleeve minimizes dripping and running of excess liquid down the outside of the sleeve after pouring. In one embodiment, detent mechanisms are provided to accurately locate different measurement positions of the sleeve.
