Abstract
A plastic pail lid opening surrounded by an upstanding closure receiving cylindrical neck is modified to incorporate a shorter outer cylindrical collar surrounding the neck. A closure assembly made up of an internally threaded closure fitment and a hand applied plug is affixed to the opening neck. The threaded opening is surrounded by an integrally molded sealing channel having an axially extending inner wall and a peripheral interlocking outer wall. To secure the closure assembly to the pail opening the inner wall is guided within the opening neck while the outer wall is axially forced between the outer surface of the upstanding neck and the inner diameter of the surrounding cylindrical collar. With the sealing channel outer wall interlockingly squeezed between the opening neck and surrounding collar, a liquid tight tamper resistant connection is formed.
