<p>PROBLEM TO BE SOLVED: To provide an extraction tool for a bag body, a bag body with the extraction tool, a formation metal mold of the extraction tool for the bag body and a manufacturing method for the extraction body for the bag body, in which a blockage cylinder having barrier properties can be so disposed as to be correctly positioned in a base material resin without detachment thereof from the base material resin, and thus, easy manufacture and quality improvement can be achieved.SOLUTION: An extraction tool for a bag body is configured from a peripheral wall 10 surrounding a bung hole 5, a blockage cylinder 11 having barrier properties, and a peripheral wall body part 10a made of a base material resin in which the blockage cylinder 11 is embedded. On one end surface of the peripheral wall body 10a in an axial direction, plural depressions 13, which are depressed towards one end surface of the blockage wall 11 embedded in the peripheral wall body part 10a in an axial direction, are intermittently provided along a circumferential direction. During manufacturing, a part of a formation metal mold corresponding to the depressions 13 is brought into contact with the axial one end surface of the blockage cylinder 11.</p> |
