摘要：

PROBLEM TO BE SOLVED: To provide a medical cap which prevents infusion from leaking and prevents an injection needle from coming-off.

SOLUTION: A molding method of a stopper for the infusion is a method for compression-molding a single body stopper for the infusion which is joined to an outer frame body to be mounted on an infusion container and is composed only of an elastomer resin that the injection needle punctures to take out the infusion from the infusion container by filling the elastomer resin of a raw material into a die. The elastomer resin of the raw material with a shape which is formed by being extruded and cut out from an extruding machine is supplied to the surface of the lower die of the die, and the lower die and an upper die directly apply pressure to the raw material in the die by the approach of both the dies. The raw material is filled into the die while being crushed and the raw material filled into the die comprising the upper die and the lower die is compression-molded. Thereafter the die is separated and the stopper is cooled, and the stopper without irregularities due to the flow of the resin is obtained by molding the stopper which is a cooled molded article that is taken out from the stopper.
