PROBLEM TO BE SOLVED: To provide a pilfer-proof cap hard to be deformed at the high temperature filling time of a content and also in a hot vender for holding up a packing securely at the time of opening a cap and preventing the leakage of the content at the time of freezing. SOLUTION: A pilfer-proof band 5 is connected with a peripheral wall lower section of a cap main body 1 with a top plate 2 on the upper section of a peripheral wall 3 formed on the inner peripheral of a female screw 31 screwed with a male screw 71 of a bottle mouth 7 through a plurality of breakable bridges 4..., and a packing 6 with a middle leg 64 fitted closely on the bottle mouth 7 is set on the inner face of the top plate 2 of the cap main body 1, and the outer peripheral end edge 61 of the packing 6 is formed thicker than that of the top plate 62, and the inclination angles of the horizontal faces of a contact faces 63 of the outer peripheral end edge 61 and a contact face 33 of a packing guide section 32 of the cap main body 1 are formed equal so that the faces are brought into face contact each other. |
