ABSTRACT:
A closure assembly is provided that includes an outer cap with a skirt dimensioned to telescope over the open top end of the tube. An annular shoulder extends inwardly from the top end of the skirt and includes an aperture through which a needle may be directed. A laminated seal is bonded to the bottom surface of the annular shoulder of the outer cap and extends continuously across the aperture in the annular shoulder. A stopper is secured on the bottom surface of the annular seal and is dimensioned for sealing engagement in the open top of the tube. Outer circumferential portions of the bottom surface of the laminated seal between the skirt and the stopper are bonded to the open top end of the tube. The bond between the closure and the laminated seal is stronger than the bond between the tube and the laminated seal. Thus, the closure assembly retains its structural integrity after opening of the tube and can be used to reseal the tube.
