Producing flange cap useful for container for holding pharmaceutical substance, comprises molding a material strip exhibiting a pre-plastic-coated film layer to flanged cap by punching and deep drawing

摘要

Producing a flange cap comprising a metallic film layer (1), which is covered at the outer side with a plastic layer forming a coating of the film layer, comprises molding a material strip exhibiting a pre-plastic-coated film layer to the flanged cap by punching and deep drawing. Independent claims are also included for: (1) the flange cap comprising the metallic film layer, the plastic layer forming the coating of the film layer, and an additional flange cap-marginal edge (11), where the flange cap-marginal edge exhibits a cutting edge passing through both the film layer and the plastic layer (2, 3), and the flange cap-marginal edge is covered by a portion of the plastic layer, which is stretched compared to the plastic layer; and (2) the container comprising the pharmaceutical substance, preferably ampoule, where the container is closed with the flange cap and the flange cap exhibits the metallic film layer.
