Abstract
A metallic container closure comprising a shell of a thin metal sheet having a circular top panel walland a skirt wall, and a synthetic resin liner arranged in the shell, the skirt wallhaving a thread-forming region and an annular groovepositioned at an upper end portion of the thread-forming region, wherein an internal pressure release line A extending in the circumferential direction is arranged in the skirt wallat a portion over the annular groove, and annular beadis arranged so as to pass through between the internal pressure release line A and the annular groove. The metallic container closure effectively releases the gas when the pressure in the container is elevated and effectively prevents the skirt wall from being deformed at a portion where the internal pressure release line A is formed when it is being wrap-seamed with the mouth-and-neck portion of the container.
