Abstract
Abstract A measuring cap for use on containers is disclosed. This cap has a hollow cap body divided into an entrance chamber and a measuring chamber by an internal wall. A lid is rotatably mounted on the top of the cap body so as to be capable of being rotated between a closed position covering the top of the body and an open position in which the top of the body is uncovered. A valve member is attached to the lid so as to rotate therewith. This valve member is formed so that when the lid is in a closed position, the two chambers are in communication with one another and so that when the lid is in an open position the entrance chamber is covered.
