PROBLEM TO BE SOLVED: To provide a container with a screw without need of changing liners and capable of raising a first torque of an opening torque to a necessary level.SOLUTION: A container with a screw has a body 2 with a male screw 2a formed on the opening 2b to which a metal cap is attached in a screwing manner. The metal cap includes: a cap body consisting of a top panel part and a sleeve-like peripheral wall hanging from the periphery of the top panel part and a pilfer-proof part connected by multiple bridges under the sleeve-like peripheral wall; and a liner provided in the inner surface of the top panel part. The opening part has a swelling part 2e having a bottom surface formed swelling under the male screw and the pilfer-proof part pressure bonded thereto in a slanting manner against the central axis C. The swelling part has a part D1, whose bottom surface or side surface in the cross section perpendicular to the central axis, at least partly warps inward from a true circle shape. |
