Abstract (en)
[origin: US2003231988A1] Protected stopper for test-tubes, which comprises a substantially cylindrically extending elastomer inner body (3) which can be arranged so as to close a test-tube (2) and is provided with a sealing portion (4) formed so as to be inserted inside the mouth of the test-tube (2) and a collar piece (5) connected above the sealing portion and projecting radially with respect to the latter so as to receive, in bearing contact therewith, the mouth of said test-tube (2). The stopper (1) comprises moreover a substantially cylindrical cover (6) made of plastic, closed at the top and mounted so as to cover the inner body. Engaging means for simultaneously securing the inner body to the cover and the whole stopper to the test-tube (2) are envisaged. These engaging means consist of a plurality of projections (11) which extend on the inside of the side wall of the cover (2), come into contact with the outer wall of the test-tube (2) and are spaced from the closing wall of the cover (6) so as to form a contact step capable of constraining the projecting collar piece (5) of the inner body (3).
