ADJUSTABLE MEASURING DEVICE

摘要

Adjustable measuring device (10) has a cylindrical base (12) and a cylindrical sleeve (14) which slides upwardly and downwardly on the cylindrical base (12) to form a cup of variable volume. Both cylinders (12, 14) 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 (70) having a relatively thin, flexible wiper (72), forms a seal at the junction between the sleeve (14) and the base (12) and minimizes leakage from the device (10). A lip (88) on each narrow end of the sleeve (14) minimizes dripping and running of excess liquid down the outside of the sleeve (14) after pouring. Detent mechanisms (40, 44) may be provided to accurately locate different measurement positions of the sleeve (14).
