A composite closure arrangement is provided for blood sample collection tubes, and particularly evacuated blood collection tubes for reducing exposure of a technician to any blood droplets or blood aerosol during removal of a sample of the blood from the container. The device also hides and contains any such aerosol or droplets. Moreover, the device provides enhanced ease of removal of the stopper, when desired. A cap is configured to be placed over and fitted onto the rubber stopper of the tube, with the top portion of the cap extending over and spaced from the top of the stopper to define a cavity between the overlying portion of the cap and the top of the stopper. The center of the overlapping portion of the cap includes a sample needle access bore providing access to the stopper diaphragm. Cooperating opposed abutments on the cap and the stopper maintain the cap on the stopper. |
