Claims

[Scope of utility model registration request]

It is a metal cap constructed by fixing an elastic soft synthetic resin liner 6 to the bottom surface of a top plate 3 of a metal shell 2 having a cylindrical shape, and is assembled to seal the bottle opening 13. The liner 6 is constructed by continuously providing a circumferential protrusion 9 bulging downward on the outside of the packing plate part 7 which is pressed against the upper end surface 14 of the bottle opening part 13 when the bottle mouth part 13 is pressed. When the metal shell 2 is press-curved and assembled to the bottle mouth part 13, the position of the fixed edge 11, which is the fixed outer peripheral end to the lower surface of the top plate 3, is adjusted to the outer curved corner of the upper end surface 14. A thin metal plate cap set to be located below the center of curvature O of No. 15.
