Abstract: A metallic container closure including a shell of a thin metal sheet having a circular top panel wall (7) and a skirt wall (9), and a synthetic resin liner arranged in the shell, the skirt wall (9) having a thread-forming region and an annular groove (17) positioned 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 wall (9) at a portion over the annular groove (17), and annular bead (30) is arranged so as to pass through between the internal pressure release line A and the annular groove (17).

Abstract: A metallic container closure comprising a shell of a thin metal sheet having a circular top panel wall 7 and a skirt wall 9, and a synthetic resin liner arranged in the shell, the skirt wall 9 having a thread-forming region and an annular groove 17 positioned 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 wall 9 at a portion over the annular groove 17, and annular bead 30 is arranged so as to pass through between the internal pressure release line A and the annular groove 17. 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.

Abstract: A package comprising a metallic container having a mouth portion and a metallic cap with a liner fitted to the mouth portion, wherein the liner 17 of the cap includes an outer ring 20 hanging down from an outer circumferential end thereof and an inner ring 21 hanging down on the inside of the outer ring 20; the inner surface of the outer ring 20 extends straight in the vertical direction; and a corner portion from the top panel to the skirt is draw-formed while pushing the cap from the upper direction in a state where the open end of the container mouth portion is inserted, so that the inner surface of the outer ring is brought into close contact with the outer surface of the side wall portion formed at the open end of the container mouth portion, an inner protruded portion is formed at the lower end of the inner surface of the outer ring so as to protrude inward, and the inner protruded portion is brought into close contact with the outer side portion of the lower curled portion of the container mouth portio
