<p>A plastic paid lid or the like (30, 40, 50) has a neck construction comprising an opening surrounded by a neck (31, 43, 51) incorporating a locking collar (33) surrounding the neck; a closure assembly (1) has an integrally moulded sealing channel (9) having an axially extending inner wall (10) and a peripheral interlocking outer wall (14); the closure assembly is secured to the neck construction with the spout inner wall guided within the neck opening and the spout outer wall axially forced between the outer surface of the upstanding neck and the inner diameter of the surrounding collar; whereupon the sealing channel outer wall is interlockingly squeezed between the neck and the surrounding collar to form a liquid-tight, temperesistant connection.</p> |
