Problems solved by technology

One disadvantage, for example, is that liquid that emerges outside the spout, and thus the bag, makes the bag dirty or sticky
On the other hand, this also creates hygienic problems, since the liquid sticking on the outside is not protected by the sterile packaging of the bag

Embodiment Construction

[0025] figure 1 A device 1 for filling foil-lined bags 2 with a spout 3 is shown. The spout 3 of the foil-lined bag 2 fits onto the fill hole 4 . Here, the spout 3 can be inserted or pulled into an opening (for example a small tube) from below.

[0026] The liquid supply line 5 is arranged on the side of the main pipe 31 . The main pipe 31 extends in a direction transverse to the liquid supply line 5 and is oriented vertically up to the filling hole 4 . The lower end of the main tube 31 has a tapered inner side 7 .

[0027] A filling valve 6 is arranged above the filling opening 4 . The filling valve 6 comprises an annular seal 8 which can be pressed against the conical inner side 7 . Here, the seal 8 is arranged on a movable piston 13 which is movable up and down in direction 15 . The seal 8 can also be arranged on or in the conical inner side.

[0028] figure 1 Piston 13 is shown in its lower position, with seal 8 resting on inner side 7 , thus representing closed fi...

Abstract

The present invention relates to a method for filling liquids into foil bags with a spout, the method comprising the steps of: mounting the spout on a filling orifice; evacuating the foil bag through the spout; filling the foil bag with the liquid through the spout; sucking liquid out of the filling orifice; discharging a sterile gas through the spout into the foil bag. Furthermore, the present invention relates to an apparatus for filling liquids into foil bags with a spout, the apparatus comprising: a filling orifice for mounting the spout of the bag on the filling orifice in a spout position; a liquid path which leads from a liquid supply line to the filling orifice, the liquid path being adapted to be shut off with a filling valve; a gas path which leads from a gas supply line to the filling orifice, a gas valve being provided in the gas path, and the gas path terminating downstream of the filling valve in the liquid path, and the gas supply line being connectable either to a vacuum line or to a sterile gas line.

Description

technical field [0001] The invention relates to a method for filling a liquid into a foil-lined pouch comprising a spout. Background technique [0002] Various methods and apparatus are known in the art for filling liquids into foil-lined pouches including spouts. [0003] The known method has the disadvantage that the outside of the nozzle is sometimes wetted by liquid. [0004] It has been found that this brings with it some disadvantages. One disadvantage, for example, is that liquid appearing outside the spout, and thus outside the bag, makes the bag dirty or sticky. On the other hand, this also creates hygienic problems, since the liquid sticking on the outside is not protected by the sterile packaging of the bag. Contents of the invention [0005] It is therefore an object of the present invention to provide a method and a device for preventing external wetting of the spout. This object is achieved by a method according to claim 1 and a device according to claim ...
