Abstract: 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.

Abstract: Embodiments of the invention include a fluid transfer device, for example, for medical fluids. The device includes a housing, two piercing elements mounted in the housing, and a slide arranged between the piercing elements. The slide may be displaced with respect to the piercing elements such that, in a first position, a flow connection is established between the two piercing elements, and, in a second position, a flow connection is established between one of the piercing elements and a lateral opening of the housing. In the area of the lateral opening, the housing may have a connector for insertion of a syringe cone of a syringe. When the syringe cone is inserted into the connector, the front end of the syringe cone may move the slide from the first position to the second position.
