PROBLEM TO BE SOLVED: To dent the body of a container without exerting an excessive force to the container, in a container-hermetically-sealing device. SOLUTION: By moving linear materials 49 and 50 into a storage hole 45 from guide grooves 47 and 48 respectively, with a lid 18 kept on a container main body 12, the linear materials 49 and 50 compress and dent the body 13 of the container main body 12 from the left and right, so that the capacity of the container main body 12 decreases. By pressing a flange 17 under the condition and forming a thigh seal by welding, and then by returning the linear materials 49 and 50 into the guide grooves 47 and 48 respectively, the body 13 elastically restores its original state and the capacity of the container main body 12 returns to its original capacity, so that inside pressure of the container 10 is reduced. Because the body 13 of the container main body 12 is compressed in the direction of its diameter by the linear materials 49 and 50, an excessive force is not exerted to the body 13, unlike the case the body 13 dented by being pushed into a narrow space. |
