成形により効率よく行うことができる。This container plug is formed by penetrating the flange 2 and an aggregate 2 consisting of a flange 1 and a small-diameter extension 9 extending downward from the flange 1. The aggregate 1 is made of a hard plastic such as polyamide, polypropylene, polycarbonate, or polyimide. On the lower surface of the flange 1, a step is formed from the contact portion 7 to the container upper surface 6 and the corresponding contact portion 7 to form the flange portion 1.
A seal portion 5 including an insertion portion 8 that is inserted into the container mouth portion 4 having a smaller diameter is connected to the needle stick portion 3 so as to cover the extending portion 9 of the aggregate 2 and is formed of a soft material. Has been done. The flange 1, the needle stick portion 3 and the seal portion 5 are simultaneously formed integrally by injection molding. This molding can be efficiently performed by two-color molding.

再び密封される。The method of using the container stopper of the present invention will be described. First, the flange portion is held by hand or is gripped by the chuck portion of the automatic machine, and the insertion portion 8 of the seal portion 5 is inserted into the container mouth portion 4. Fit inside. In the flexible seal portion 5, the insertion portion 8 is in close contact with the inner peripheral surface of the container mouth portion 4, and the contact portion 7 is in contact with the upper surface of the container to be hermetically sealed. When the sample is taken out after the sealing, the injection needle is inserted into the needle stick part 3, and when the injection needle is taken out after the sample is taken, the punctured hole is closed and sealed again.
