摘要: A metal cap in which a linear to be held to a cap body and separable from the cap body can be formed by a series of operations for forming the cap body and press molding the liner. The liner of the metal cap has a double-layer structure including a barrier layer on a top panel wall side and a sealing layer on the inner side of the cap body, and the barrier layer is temporarily bonded to the top panel wall with a weak adhesive at the time of molding the barrier layer and separated from the top panel wall by the natural cooling of the barrier layer after molding.
