Abstract
The shower base (1) of a shower head consists of a rigid perforated plate (1a), which has a number of holes (4, 5). Set inside each of the holes (4, 5) in the perforated plate (1a) is a hose-type jet insert (6, 8) made of a flexible material which, owing to its material properties, can be automatically flexed to dislodge limescale deposits. The shower base (1) is sealed against the rest of the shower head, in particular against its housing (2) by means of one or more seals (25, 29). This/these seal(s) (25, 29) is/are made of the same material as the jet inserts (6, 8) and is/are manufactured jointly with these, for preference connected in one piece. In this way, it is not necessary for the seals (25, 29) to be manufactured, kept in store and assembled separately.
