According to this configuration, the steaming fastener part 172 is separated from the opening fastener part 171 by separating the steaming seal part 152 from the steaming part 140 by the steaming guide wire 162. For this reason, the operation | work which isolate | separates the steaming seal part 152 from the steaming part 140, and the work which isolate | separates the steaming fastener part 172 from the opening fastener part 171 become one continuous work.

  (6) The cutting part 163 of the bag 110 has a first predetermined cutting part 165 and a second predetermined cutting part 166. According to this configuration, the bag predetermined portion 137 can be easily separated as compared with the configuration in which the first predetermined cutting portion 165 and the second predetermined cutting portion 166 are not provided.

  On the other hand, when the force that separates the portion on the extension line of the intermediate cutting portion 164 in the bag 110 acts on the bag 110 due to having the first predetermined cutting portion 165 and the second predetermined cutting portion 166, in the bag predetermined portion 137 There is a possibility that the portion closer to the internal space 119 than the end of the second predetermined cutting portion 166 cuts in order from the second predetermined cutting portion 166. And when the cutting | disconnection which arises in order from the 2nd predetermined cutting | disconnection part 166 reaches | attains the internal space 119, the internal space 119 will no longer be sealed.

  The bag 110 forms an interrupted portion 167 between the first predetermined cutting portion 165 and the second predetermined cutting portion 166 based on such prediction. According to this configuration, when the force that separates the portion on the extension line of the intermediate cutting portion 164 in the bag 110 acts on the bag 110, this force acts as a force for cutting the interrupting portion 167. For this reason, the possibility that the portion of the bag predetermined portion 137 closer to the internal space 119 than the end portion of the second predetermined cutting portion 166 will be cut sequentially from the second predetermined cutting portion 166 is reduced.

  (7) The bag 110 has a cutting suppression portion 138. According to this structure, when the force which isolate | separates the part on the extension line of the intermediate | middle cutting part 164 in the bag 110 acts on the bag 110, it is suppressed that the bag predetermined part 137 is cut | disconnected to the internal space 119 by this force. .
