发明名称 CONTAINER CLOSURES AND METHOD
摘要 <p>A losure cap having a downwardly depending band at least partially severable therefrom along a substantially annular tear line. At least the depending band is of heat deformable thermoplastic material and after positioning is heat deformable into locking engagement with the container. The inner surfaces of the cap and band are adapted to the outer surface of the container whereby before heat deformation the band abuts on the container in the region of the tear line so that the band is protected against excessive heating by heat conduction into the abutting container.</p>
