FASTENING OF A DISPENSING HEAD TO THE NECK OF A BOTTLE

摘要

The intermediate piece (5) has a tubular shape and a central channel for the passage of fluid. At one end it has an inner thread which can be screwed on to the outer thread (3) of the neck of the bottle. At its other end is an outer thread (10) in which is screwable the inner thread of the dispensing head (15). The intermediate piece on its outer surface has a ring flange, which forms a ring groove facing the bottle (1), so that the bottle can be suspended, preferably in a clamped fashion, in a holding component (14). The inner thread of the intermediate piece has a smaller diameter than its outer thread. The ring flange is provided approximately in the centre of the axial length of the intermediate piece.
