Abstract
A metering pouring stopper comprising two elements of a moldable or injectable material which is at least somewhat flexible. One of these elements comprises a pouring lip which can be fastened to the free end to the threaded neck of the container, while the other element comprises a metering chamber and a threaded skirt to be screwed onto the threaded neck of the container. Since the threads of the necks of containers always have a predetermined, constant angular orientation, the two elements of the stop that can fit into one another have assembly detachable means which make it possible to assemble them temporarily before they are placed onto the container. Means are provided whereby the elements can be set and positioned angularly relative to one another by relative simple rotation of a fraction of a turn, this angular positioning being determined as a function of the predetermined and constant angular orientations of the threads of the neck of the container and of the closing element of the stopper so that, when the stopper is completely screwed onto the neck of the container, the pouring lip of the element bearing the pouring lip has the desired angular orientation diametrically opposite to that of the handle of the container.
