ABSTRACT:
A plastic pourer for insertion into the mouth of a bottle-like container, the pourer including a sealing flange at least partially covering the rim of the bottle mouth and also including a hollow cylindrical wall part bearing against the inside of the mouth. The container is closable with a cap. To insure secure seating of the pourer in the mouth through a large range of tolerances, at least two radically and axially extending feasible holding struts are carried by a hollow inner cylindrical part of the pourer, the struts extending for part of their axial length along the outer periphery of the inner cylindrical part and also beneath the inner cylindrical part. The struts bear elastically against the inner wall of the container mouth with a pressure greater than the holding pressure on a mandrel-like holder carried by the cap for inserting the pourer into the container mouth.
