PROBLEM TO BE SOLVED: To obtain a sealing member which can be surely torn by possessing a tear part whose one end is provided in a sealing part, whose other end is connected to a connection edge and which is provided in an extending direction by coupling one end with the other end. SOLUTION: This member possesses the tear part which can be torn in order to unseal an aperture part sealed by the sealing part, whose one end is provided in the sealing part, whose other end is connected to the connection edge and which is provided in the extending direction by coupling one end with the other end. In other words, a tear seal member 17 as the sealing member possesses a cover seal part 17a as the sealing part sealing the aperture part 12a1 and stuck to a flange 12a2 by thermal sealing. The member 17 possesses a pulling-out part 17b as an extending part extended from the seal part 17a. The seal part 17a and the pulling-out part 17b are integrally constituted of one sheet and folded and piled to be constituted as the member 17. |
