Abstract
A dispensing closure device for sealing engagement over the mouth of a container comprises a body with an orifice therethrough, a stopper mounted on the body positionable within the orifice and a cap movable relative to the body between open and closed positions. The cap has a closure, e.g. in the form of a cam, for retaining the stopper in an orifice-closing position when the cap is in its closed position and for enabling the stopper to move out of its orifice-closing position when the cap is in its open position. The stopper is resiliently biased away from its orifice-closing position.
