<p>A pierceable stopper (5) for a liquid container (1), which has a pierceable part (11) made of a thermoplastic synthetic resin elastic material. The pierceable part is formed so as to prevent leakage of liquid from the container when it is pierced with a hollow needle. The pierceable part is confined in a compressed state in the stopper body (10) of the pierceable stopper. A molten thermoplastic synthetic resin elastic material is injected into an injection mold at an injection pressure higher than the normal injection pressure to mold the pierceable part. <IMAGE></p> |
