A valve unit is fixed in the drink reservoir on its upper surface and comprises a valve body displaced in direction of closure to the valve seat, and has an engagement facility that stretches beyond the inner space limits. A pressure adjustment device comprises a reservoir filled with compressed gas and communicated with the inner space during use. A dispenser comprises a driving device to release the valve body from the valve seat. The driving device includes a part of a channel for drink dispensing and is equipped with a facility to maintain the valve unit in open condition. The driving device is equipped with the first and second connecting facilities. The second connecting facility may move in the first connecting facility for displacement of the valve body from the valve seat. The engaging element for engagement of the specified engagement facility and/or the first connecting facility is made to retain the specified valve body in the position displaced from the valve seat. The first and/or the second connecting facility is made with the possibility of attachment to the reservoir.
