Claim:
A device for treating a flowing liquid comprising; a chamber containing a treatment medium, an inlet through which liquid enters the chamber, an outlet through which liquid can leave the chamber in which a plate is provided, the outlet having a dimension sufficient that a user could come into direct physical contact with the plate through the outlet during use, the plate having at least one opening extending through it positioned such that liquid passing out of the chamber passes through the opening for discharge from the device; in which the outlet includes a skin located downstream of the plate which surrounds the plate so that the plate is recessed from the outlet end of the device defined by the edge of the skirt, and the skirt has a geometry defining an unconstrained flow path from the plate to the outlet end of the device, the ratio of i) the depth of the skirt from the plate to the outlet end of the device to ii) the width of the outlet, being at least 0.2, and a peelable protective cover which is attached to the edge of the skirt at the outlet end of the device to prevent ingress of contaminants into the device at its outlet end.
