Nozzles for filler pipes employed in packaging machines of the type which meter a certain quantity of contents, e.g. milk, into individual packages which are advanced stepwise and placed beneath the nozzle of the filler pipe. In order to avoid frothing of the contents, of the nozzle is manufactured from flexible material and includes one or more transverse rigidifying ribs which are of substantially triangular cross sectional configuration and which define two or more separate outlets. The outlets are covered by flaps which are opened by the contents when the contents are caused, with the aid of a metering pump, to flow out through the filler pipe so that the flow of contents is divided and directed towards the vertical walls of the package via which the contents flow down to the bottom of the package with a considerably reduced risk of frothing and spatter as a result. |
