Title
(EN) MEDICINAL VIAL STOPPER
(ZH) 药用瓶塞
Abstract
(EN)
A medicinal vial stopper has a stopper plug extending from a stopper flange. The stopper plug is insertable with a compression fit in the neck of the vial. A first bore within the stopper plug has a radially inwardly facing first-bore surface having a constant first-bore diameter the entire first-bore length and a first-bore first end closed by a centrally-located piercable portion of the stopperflange. A second bore within the stopper plug has a radially inwardly facing second-bore surface having a constant second-bore diameter the entire second-bore length. The second-bore diameter is greater than the first-bore diameter. The second-bore first end is in fluid communication with the first-bore second end. The centrally-located piercable portion of the stopper flange is resiliently deformable and upon being pierced by a spike tightly conforms to the radially outwardly facing sidewall of the shaft; thereby forming a fluid impenetrable seal.

(ZH)
一种药用瓶塞,其具有从塞子凸缘延伸的塞头。该塞头压缩配合插入小瓶的所述颈部。位于塞头内的第一孔具有径向朝向内的第一孔表面,其具有整个第一孔长度的恒定的第一孔直径,以及第一孔第一端由塞子凸缘的中心位置的可穿透部分封闭。位于塞头内的第二孔具有径向朝向内的第二孔表面,其具有整个第二孔长度的恒定的第二孔直径。第二孔直径大于第一孔直径。第二孔第一端与第一孔第二端流体连通。塞子凸缘的中心位置的可穿透部分是可弹性变形的,并且在被尖头刺穿时紧密地与杆部的径向朝向外护面侧壁吻合,从而形成流体不可渗透的密封件。
