Zusammenfassung:PROBLEM TO BE SOLVED: To provide a cap with a liner and a container with a cap capable of reducing pressure in the container in a short time from the start of opening, and preventing cap jumping during the opening.SOLUTION: A cap 10 with a liner includes a cap body 40 having a top part 41 and a cylindrical part 42 roughly drooped from the peripheral edge of the top part 41, and a liner 50 provided in the inner surface of the top part 41, and seals the cap part 21 of a bottle can 20 (container). When the bottle can 20 is sealed again with the cap 10 with the liner to set the internal pressure of the bottle can 20 to 600 kPa, the internal pressure of the bottle can 20 is reduced to 150 kPa or lower when the cap 10 with the liner is rotated by 180° in a peripheral direction from a closed position to open the cap part.SELECTED DRAWING: Figure 1 【課題】開栓を開始してからより短時間で容器内部の圧力を低下させ、開栓時のキャップ飛びを防止することができるライナ付キャップ及びキャップ付容器を提供する。【解決手段】天面部41とその天面部41の周縁から略垂下されてなる円筒部42とを備えるキャップ本体40と、天面部41の内面に設けられたライナ50とを有し、ボトル缶20(容器)の口金部21を密栓するライナ付キャップ10であって、ボトル缶20にライナ付キャップ10を再栓してボトル缶20内部の内圧を600kPaとした場合において、ライナ付キャップ10を閉止位置から周方向に180°回転させて開栓した際に、ボトル缶20内部の内圧が150kPa以下に低下する。【選択図】 図1
