<p>A water filter jug contains a hopper (1) accommodating a removable filter (3) and has a spout (4) which communicates only with the lower part of the jug body (2), such that water entering the hopper (1) is constrained to pass through the filter (3) and into the lower part of the jug body from which it can be poured out via the spout. A lid (5) has an aperture (6), which is closed by a slidable cover (13) operated by a thumb grip (15) and through which water is poured to enter the hopper (1). A ratchet mechanism is mounted on the underside of the lid (5) to register each time the cover (13) is opened to enable water to enter the hopper (1), thereby giving an indication of the remaining useful life of the filter (3). A visible indication of the remaining useful filter life may be provided via a window (27) in the lid (5).</p> |
