PROBLEM TO BE SOLVED: To provide a container with a lid for indicating that the pressure valve function operates, and capable of degassing without a rupture sound, without splashing exhaust gas on an opening tab from inside the container, even when an annular seal part constituted by sealing a lid material and a container body, is dislocated in any direction from a design position.SOLUTION: In the lid material 10, a reverse half-cut 11 does not exist in an area α of joining both ends of a part for contacting with the container body 20 of the opening tab 12 and the center O of the lid material 10, since at least a pair of reverse half-cuts 11 exist in an opposed position by sandwiching the center O of the lid material 10, the reverse half-cut 11 penetrates up to a separation surface from the sealant layer 5 side and one end of the reverse half-cut 11 is obliquely provided toward the inside of the lid material 10 from an inside end part 30a of an annular seal part 30. |
