It is possible to penetrate the film 16 and surely insert it into the container 10. As a result, regardless of the thickness of the first connecting portion, the film 16 of the port portion 12 can be easily and surely pierced, and the first connecting portion can be surely inserted into the container 10 to communicate with each other.
  • the vertical wall 36b of the piercing portion 36 is provided with the circumferentially inclined edge 36c that is inclined from the top portion 36a of the piercing portion 36 toward the base portion 33 toward the rotation direction, it has a step shape.
  • the top portion 36a of the piercing portion 36 can be most protruded in the direction of the axis L1.
  • the vertical wall 36b of the piercing portion 36 is provided with the inner peripheral inclined surface 36d which is inclined radially inward from the outer peripheral edge on the tip side of the piercing portion 36 toward the base 33 side, the top portion 36a of the piercing portion 36 is provided. Can be sharply formed on the outer side in the radial direction.
  • the circumferential slanted edge 36c and the inner circumferential slanted surface 36d cooperate with each other so that the top 36a of the stepped piercing portion 36 provided at the tip end 35a of the tubular portion 35 is closer to the inner peripheral edge of the port portion 12. Only part of it can be sharply pointed. As a result, it is possible to pierce the position of the film 16 that is closer to the joint portion with the port portion 12 by the piercing portion 36 that is sharply sharpened, and it is possible to prevent a piercing defect due to stretching of the film 16 or the like.
  • the vertical wall 36b of the piercing portion 36 is provided with the circumferentially inclined vertical surface 36e that is formed at an acute angle with respect to the tangent line L2 of the outer peripheral edge of the piercing portion 36 on the tip side,
  • the film 16 can be reliably cut by the circumferentially inclined vertical surface 36e formed at an acute angle.
  • the opening is formed in the film 16 by the locus of the rotation of the circumferentially inclined vertical surface 36e, the opening corresponding to the outer peripheral shape of the tubular portion 35 can be reliably formed, and the tubular portion of the first connecting portion 31 can be surely provided. It is possible to insert and arrange 35 through the film 16.
  • a push-out portion 38 that pushes the cut piece 16a formed by rotating the piercing portion 36 to the outside of the tubular portion 35 is provided at a position that faces the piercing portion 36 in the radial direction. Therefore, the cutting piece 16a formed by the rotation of the piercing portion 36 can be pushed out to the outside of the tubular portion 35.
  • the cutting piece 16a formed by the rotation of the piercing portion 36 is located inside the tubular portion 35. Even if it is tilted to the side, it can be smoothly raised by the outer peripheral inclined surface 38a and can be pushed outward in the radial direction by the pushing portion 38. As a result, it is possible to reliably prevent the flow path of the first connecting portion 31 from being blocked by the cutting piece 16a, and the distribution of the contained matter between the first connecting portion 31 and the second connecting portion 32. It is possible to secure the sex.
  • the opening corresponding to the tubular portion 35 of the second connecting portion 32 can be easily and surely provided regardless of the thickness as described above, and as a result, the first connecting portion 31 is semi-solidified.
  • the semi-solidified nutrient can be directly sucked from the container 10 to the catheter tip syringe 20 by inserting the same into the container 10 containing the agent and connecting the second connecting portion 32 to the catheter tip syringe 20. Therefore, the semi-solidified nutrient can be used by directly storing it in the catheter tip syringe without transferring it to another container, and it can be used for storing the semi-solidified nutrient from the container 10 to the catheter tip syringe 20. At this time, it is possible to reliably prevent foreign matter from entering, and it is possible to hygienically perform the housing operation. Further, the work efficiency of the housing work can be improved.
  • the rotation amount of the connector 10 with respect to the port portion 12 of the container 10 is regulated within a range not exceeding 360 degrees, the film 16 is cut by rotating the piercing portion 36.
  • the cut pieces 16a thus produced are not likely to come off, and can be used safely.
  • the flexible container 10 has been described as the container 10 into which the first connecting portion 31 is inserted, but the present invention can be applied to other containers such as a hard container, and the port portion.
  • the container 12 is not limited as long as it is a container sealed with a film 16.
  • a highly viscous container such as a semi-solidified nutrient is contained as the container 10 is described, but the container is not particularly limited as long as it has fluidity.
  • the present invention is also applicable to liquids having low viscosity, for example.
  • the syringe has been described as the device connected to the second connecting portion 32, but the device may be, for example, a tube, a discharge port, a valve, or the like, and a connecting method with the second connecting portion 32 is also possible. Not limited to fitting, various connection methods such as screwing can be adopted.
  • the female screw portion 33a is provided on the base portion 33 and is mounted by being screwed into the male screw portion 14a of the port portion 12 of the container 10, but the mounting method of the base portion 33 and the port portion 12 of the container 10 is as follows.
  • the base 33 is not particularly limited as long as it can be mounted by rotating the base 33.
