  • Medical container stopper
    Patent number: 5060659
    Abstract: A stopper for medical containers such as blood collection tubes having integral flange and plug portions, the flange portion being substantially larger in diameter than the plug portion, which plug portion is sized to sealably close the container. The stopper has opposed wells formed in the flange and plug portions, the well in the flange portion having a relatively flat bottom surface at least as large in diameter as the diameter of the opposed well in the plug portion. The flange portion is constructed to be guided into a tube holder into which it is inserted such that one end of a needle projecting into the interior of the tube holder will penetrate the stopper in the area of the opposed wells so as to avoid otherwise contacting the stopper. The enlarged flange portion also serves to facilitate removal of the stopper from the container without contaminating a handler.
