First Claim
1. An arrangement for a tapping tube intended for the filling of container-like receptacles, such as bottles (18), with a liquid, said tapping tube preferably communicating with a metering pump, and arranged to carry out a reciprocating vertical movement in relation to the receptacles (18) in question in connection to the object change, whereby the liquid in question is intended to flow through the tapping tube and to be interrupted during replacement of the receptacles in question, characterized in that there is connected to the tapping tube (1) a suction channel (14) which discharges in the lowest point of said tapping tube and which is so arranged as to be actuated in such a way as to provide a suction effect at least for the duration of the afore-mentioned interruption in the flow of liquid through the tapping tube (1), by means of control arrangements which are provided for the activation of the suction channel (14) only in conjunction with the interruption of the flow of liquid through the tapping tube (1), for example during removal and replacement of the receptacles, for the purposes of preventing dribbling or dripping during removal and replacement of the receptacles, wherein in combination therewith there is present, with the tapping tube (1) in its position lowered into the receptacle (18) to a position capable of being below the liquid level in the receptacle, an open discharge outlet (15) operated above the liquid level for foam, excess liquid and gas.

Abstract
The invention relates to a tapping tube intended for the filling of container-like receptacles, such as bottles, with a liquid, said tapping tube preferably communicating with a metering pump, whereby the liquid in question is intended to flow through the tapping tube and to be interrupted during removal and replacement of the receptacles in question. An arrangement for a tapping tube of this kind is made available in which above all dribbling and dripping can be prevented, especially in conjunction with the removal and replacement of the receptacles. There is connected to the tapping tube (1) a suction channel (14) which discharges in the vicinity of its lower end and which is so arranged as to be actuated in such a way as to provide a suction effect at least for the duration of the aforementioned interruption in the flow of liquid through the tapping tube.
