The feed connection between the supply container (1) and each of the closing chambers (2,20) and between the two closing chambers (2,20) is controlled by a multi-way tap (21). A four-way valve is pref. used with a blocking position, a position in which the container (1) is coupled to one closing chamber (2) while the other is coupled to the discharge outlet (8). In another position the second closing chamber (20) is coupled to the container (1) and the first closing chamber (2) is coupled to the outlet (8).
