Abstract

PURPOSE:To automatically feed a charging material separately into respective containers of a packing bag which is provided with two independent containing spaces partitioned by a dividing film in the bag. CONSTITUTION:A dividing film 24 is interposed between external face films 22, 23 and both side edges and the bottom edge are sealed by welding to mane a sort packing bag. Suction holes 29, 30 are formed on the opening edges of respective external face films. At first, a sucker 49 is put apart from the suction hole 29 of the external film 22 and a sucker 52 is put at the position covering the suction hole 30 of the external face film 23. The sucker 49 sucks only the external face film 22 and the sucker 52 sucks the dividing film also through the suction hole 30. When both suckers are pulled, the bag opening of the containing part 27 is opened and the charging material is fed therein. When the bag opening of the containing part 28 is opened, respective sackers are reversely applied.

On the contrary, the suction plate is addressed to the one outer film at a position covering the suction hole, and the suction plate is addressed to the other outer film at a position removed from the suction hole. Yes, both sides are sucked, and one suction plate simultaneously sucks the one outer film and the split film (the side not welded to the outer film when the split film has a bag shape) through the suction holes, and the other one. The suction plate sucks the other outer film. When both suction cups are pulled in this state, the bag mouth is opened, and the packing can be put into the other storage portion this time. The suction holes formed in the packaging bag remain even after the opening edge is welded and sealed, but they are small (for example, about 3 to 5 mm in diameter), and there is no leakage of the filling material, and the appearance does not deteriorate.

Embodiments of the present invention will be described below with reference to FIGS. First, FIG. 1 shows a packaging bag 21 that simultaneously stores two types of fillers, a filler 9 (a noodle soup base) and a filler 10 (a noodle). This packaging bag 21 is similar to the packaging bag 1 shown in FIG. 10 in that a split film 24 is interposed between two outer surface films 22 and 23, and both side edge portions 25 and bottom edge portions 26 are left while leaving their opening edge portions. It is a flexible packaging bag that is fusion-sealed, and the bag mouth formed by the outer films 22 and 23 is divided by a dividing film 24, and the space inside the bag is divided by the dividing film 24 into two independent first and second portions.
It is divided into storage units 27 and 28. Further, in the vicinity of the center of the opening edge portions of the outer surface films 22 and 23, the first
The suction holes 29 and the second suction holes 30 are formed. They are displaced laterally by a distance D so that the suction holes 29 and 30 do not overlap when the opening edges are welded and sealed after filling. If the suction holes 29 and 30 overlap each other, only the split film 24 is left at that portion, which is not preferable in terms of strength.
