摘要

The supply unit (8,24) comprises a supply element (8) comprising a liquid inlet, a reservoir (12) and a pouring neck (14). In addition there is a removable mask (24) covering a part of an interior wall of the supply unit. In the pouring region formed by the neck and the end of the reservoir there are peripheral strips (13,28) forming a discrete contact zone (C1,C2) between the supply element and the mask. On either side the contact zone there are two peripheral regions in which the mask is spaced from the supply element.
