Abstract
An elastic stopper and an enclosure cap incorporating the stopper for sealing a vial while allowing piercing of the stopper. The stopper includes a disk-shaped upper portion and a cylindrical-shaped lower portion defining an interior hollow space. The lower portion is divided into a plurality of longitudinal segments by a plurality of slots. A plurality of longitudinal grooves are provided on the inside surface of the lower portion to break the surface tension between the stopper and the liquid contents of the vial that flow into the hollow space of the cap. The enclosure cap allows multiple piercing without leakage of the vial contents and prevents the vial contents from aspirating out when the stopper is pierced with a single lumen needle.
