<p>The invention relates to a transfer device (1), in particular for a container (2) whose interior is under negative pressure and which is closed by means of an elastic stopper (5). The device has a receiving cap (9) and a piercing mandril (10) for piercing the stopper. Relative to its direction of piercing, the piercing mandril is provided with a front piercing portion (20) and with a rear sealing portion (21) which is of greater diameter. In the position in which a bead (4) of the container is inserted into the receiving cap, the sealing portion contacts the stopper. In this way, a tear in the stopper, which tear has been formed by eccentric application of the device onto the container, can be sealed off.</p> |
