PROBLEM TO BE SOLVED: To provide a cap separable from a container, for holding sealability between a container mouth and the cap, even after being heated at the high temperature, in the cap for integrally molding a protection part at an interval on the outer periphery of a trunk part.SOLUTION: A cap body 3 of a cap 1 comprises a trunk part weakening line 30 for cutting-tearing a trunk part 15 in the vertical direction, a protection part 40 extending by placing a clearance 41 around the trunk part 15 from an outer peripheral part of the trunk part 15 along the trunk part weakening line 30, a protection part weakening line 45 for cutting-tearing the protection part 40 in the vertical direction, a cylindrical fitting wall part 16 for fitting a container mouth 2 between the trunk part 15 and itself and a plurality of reinforcement ribs 28 integrally projected on an inner wall surface of the cylindrical fitting wall part 16. Thus, even after being heated at the high temperature, sealability between the container mouth 2 and the cap 1 can be secured.SELECTED DRAWING: Figure 4 |
