Stopper assembly for a container for aqueous infusion and a method for making thereof |
摘要 |
<p>To provide a rubber stopper (1b) enhancing a tightening force applied on a piercing needle and a closing force of a hole caused by piercing the needle, a stopper assembly for a container (4s) for aqueous infusion attached to an opening of a main body of a container for aqueous infusion made of synthetic resin in which a rubber stopper is in a tight contact state with a rubber stopper outer supporter (2c) made of synthetic resin by receiving a compressive stress therefrom at all the side face of a barrel portion of the rubber stopper, a diameter of at least one of a top face (1bp) and a bottom face (1bq) of the rubber stopper is contracted by 1 through 10% and the top face or the bottom face is expanded, is proposed. <IMAGE></p> |
