ABSTRACT:
There is disclosed herein a combination stopper for effecting an air-tight seal with the barrel of a syringe to protect the contents from contamination. The stopper is adapted for use with either the luer tip or a needle attached to the end of the syringe barrel. The stopper includes an elongated frustoconically-shaped main body portion having oppositely disposed end walls, and the end wall at the large-diameter end of the main body portion has a generally planar and continuous surface. An elongated frustoconically-shaped luer-receiving nipple is integrally formed with and extends from the small-diameter end wall of the main body portion, with the free end of the nipple being inwardly recessed. The luer-receiving nipple is shaped, sized and constructed to receive and seal the syringe luer tip. The stopper is formed of an elastomeric material having a durometer hardness of approximately 80 so as to provide an air-tight seal when the main body portion thereof is pierced by the syringe needle or when the luer-receiving needle is friction fit with the luer tip.
