  • the storage container 10 has a recess 98 for storing the needle tube 14 in a non-contact manner, so that the needle tube 14 can be prevented from being damaged when the intradermal needle 12 is stored in the second storage portion 78. Thereby, the used intradermal needle 12 can be reused satisfactorily after sterilization or the like.
  • the container 10 can further simplify the insertion of the intradermal needle 12 into the second container 78 because the second container 78 is shallower than the first container 76. Further, the size of the entire storage container 10 is reduced, and the storage container 10 and the intradermal needle 12 can be easily transported.
  • the container 10 can be easily inserted into the second container 78 by supporting the standing state during use. Thereby, it becomes possible to prevent the needle tube 14 from being pierced more reliably.
  • the container 10 has the guide part 100 that can guide the ring protrusion 32 of the intradermal needle 12, so that the ring protrusion 32 and the guide part 100 can be positioned even if the ring protrusion 32 makes it difficult to see the needle tube 14.
  • the intradermal needle 12 can be easily accommodated in the second accommodating portion 78.
  • the 2nd accommodating part 78 may be formed deeper than the said embodiment, and the structure which covers the intradermal needle 12 after use entirely may be sufficient as it.
  • the configuration of the locking portion 94 that locks the intradermal needle 12 in the second housing portion 78 is not particularly limited.
  • the locking portion 94 can be configured such that three or more locking pieces 96 are provided in the circumferential direction of the second cylindrical wall 82.
  • the locking portion 94 may adopt a convex portion or a concave portion (including a hole in which the claw portion 36 is inserted and locked) instead of the locking piece 96, or a hole is formed in the ring protrusion 32.
  • a means for catching in the lateral hole may be provided.
  • the second cylindrical wall 82 may have a tapered surface that can be mated.
  • the second housing part 78 may have a needle puncture elastic member (not shown) through which the used needle tube 14 is punctured in the recess 98 or the like.
  • the needle puncture elastic member may be configured to hold the needle tube 14 with a strong frictional force.
  • the second cylindrical wall 82 may not have the engaging portion 94.
  • the syringe 20 is not a prefilled syringe but may be used by filling with a chemical immediately before use.
