Abstract: A decanter vessel formed of a rigid receptacle and a pouring spout unit matingly engaged about the neck of the receptacle in a sealing fashion. The pouring spout has formed therein an internal annular cavity shaped to accommodate the neck portion of the receptacle. The receptacle and pouring spout are joined by a flexible adhesive material which surrounds the neck portion of the receptacle forming both an adhesive and a mechanical bond between the receptacle and the pouring spout, sealing their junction to prevent leakage of liquid therebetween. During assembly of the decanter, the flexible adhesive material is in a liquid state to facilitate joining of the receptacle and pouring spout and assure that the material evenly and completely surrounds the neck portion and fills the annular cavity. The flexible adhesive material solidifies after assembly of the decanter vessel.
