Abstract
A decanter vessel including a rigid flask formed with an upwardly projecting neck terminating in a circular edge. Received over such neck is the annular skirt of a pouring spout unit. Such skirt being formed with a frusto conically shaped interior and including on its inner wall a set of inwardly face and upwardly angled ratchet teeth spaced from the neck to form an annular cavity. Received in such annular cavity is a locking ring, such ring having ratchet teeth formed in its exterior for engagement with the first mentioned set of ratchet teeth. The ring is contractible radially inwardly such that, when pressed upwardly into the cavity will cause the wall of the skirt to press such ring radially inwardly against the surface of the neck to thereby entrap the neck within the pour spout unit.
