A method of constructing a lined closure in which a liner having a circular base, a liner membrane and a thermoplastic adhesive securing the liner membrane to the base, is press fitted into a closure having a skirt with internal threads such that the liner engages and rides over the threads and is positioned against the internal base of the closure. Heat is applied to the liner at least around the periphery of the liner so as to melt the thermoplastic adhesive and resecure the liner membrane to the liner base. In this way, the liner membrane is resecured to the liner base so as to correct any separation between the membrane and base that might have occurred as the liner was press fitted into the closure. <IMAGE> |
