PROBLEM TO BE SOLVED: To provide a port of a medical container which prevents a tip of a puncture needle from breaking through an inner wall of a neck part. SOLUTION: A needle tube 7a of the puncture needle 7 is brought into contact with a corner part Q of the port 4 and the tip of the puncture needle 7 is brought into contact with the inner wall 6a of the neck part 6. Respective theoretical values of a distance a1 from a puncture position P to an inner wall 4a of the port 4, a distance a2 from the inner wall 4a to the tip of the puncture needle 7, a length L1 of the needle tube 7a and a height h of the port 4 are expressed by the equation 1. The medical container is made in such a manner that a designed value of the distance 2 is larger than a maximum value of the distance a2, which is determined by the equation 1, in order to make the tip of the puncture needle 7 come into contact with the inner wall 6a without breaking it. |
