Title
(EN) MEDICINAL VIAL STOPPER
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 stopper flange. 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.
