PROBLEM TO BE SOLVED: To reliably release inner pressure of a container body which increases during heating or the like to the outside.SOLUTION: A container 1 comprises: a container body 11 storing content; a fitting cylindrical part 13 detachably fitted to a mouth 12 of the container body 11; and a cap 15 having a block plate part 14 blocking an opening of the mouth 12. On the block plate part 14, a communication hole 31 communicating to the inside of the container body 11 is formed, and a block piece 32 blocking the communication hole 31 is coupled via a weakened part 33 which is breakable. On the block piece 32, an operation projection piece 34 is erected. On the cap 15, a flat part 24 positioned on an opening end edge 12a of the mouth 12 and extending along a horizontal surface orthogonal to a container axis O is formed. The operation projection piece 34 is connected to a connection piece 26 supported on the flat part 24. |
