ABSTRACT:
A cap for sealing closed the opened end of an elongated tube such as a blood drawing tube, a test tube or the like is disclosed herein and comprises an integrally formed main body constructed of a flexible material, preferably polyethylene plastic. This main body is closed at its top end, and tapers outwardly at and near its bottom end, and it includes an arrangement of annular sealing ribs, all of which allow a cap to be readily positioned over the tube to be sealed in a reliable fluid sealed fashion and readily removed from the tube without causing the substance in the tube to aerosol (in the case of liquids) or otherwise escape into the ambient surroundings.
