the neck diameter of the container 8 so as to minimize or avoid any leverage the arms 10 a 10 b are positioned at the side of the weighing device 9 which is advancing or trailing respectively in rotational direction the mounting points of the arms 10 a 10 b on the holder 7 on the one hand and the weighing device 9 on the other hand have the same distance from one another in rotational direction d and are arranged in symmetry with respect to the filling axis 6 u2032 so that the arms 10 a 10 b can extend optimally in vertical direction the weighing device 9 and the holder 7 are configured such that the two can be arranged nearby or in close vicinity relative to each other i e as closely adjacent as possible to avoid any long leverage to be more specific the holder 7 and the weighing device 9 are spaced apart from each other at a distance just sufficient to accommodate the container 8 above the handling flange 8 a between the holder and the outlet opening 6 a the outlet opening 6 a preferably ending with the lower boundary of the weighing device 9 thus the arms 10 a 10 b extend exactly vertically in a modification of the described and illustrated embodiments the weighing device may optionally also be arranged above the filling valve or at another place along the filling axis 6 u2032.
