A drinking water treatment cartridge comprises a cup-shaped receptacle (49A) for containing water treatment particles and a closure (47A) which may be irreversibly snap-fitted thereon or welded thereto. The closure (47A) has a slotted skirt portion (50A) which surrounds a circumferential array of mesh covered apertures (57A, 57B) in a neck portion (55A) of the receptacle (49A). There are mesh covered slots in a domed crown portion of the closure (47A) and there is a mesh covered outlet aperture in the base of the receptacle (49A). Each mesh is integrally moulded with the surrounding structure by which it is supported. |
