Abstract
Described is a filter cover for a purification insert (4) in a water treatment device, wherein the filter cover (5) has filter slots (7) on a conical surface portion (6) and at least one vent opening (9) in the middle of a raised connecting portion (8), and can be connected to a hollow tube (10) with a disc (11). So that operation and handling, in particular venting and manipulation by the end consumer, are improved in the case of such a filter cover, it is provided that the filter slots (7) are substantially straight and are arranged in a ring-like configuration on the frustoconical surface portion (6) which occupies about 1/3 to 1/2 of the height of the filter cover (5) and that provided on the upper outer annular surface of the disc (11) are markings (15, 16) with which there is associated an adjustable pointer (17) mounted on an arresting ring (19) which is arranged non-detachably and rotatably on the hollow tube (10).
