  Before filling the coffee powder C with the raw material supply device 40 described above, the sealing portion 51 of the longitudinal closing device 50 causes the sealing portion 21c to follow the overlapping portion Xa with respect to the overlapping portion Xa of the strip-shaped nonwoven fabric 200. And continuously attached in the longitudinal direction X.

  With reference to the mark 201 provided on the belt-like nonwoven fabric 200, the seal-attached portion 61 of the widthwise closing device 60 causes the seal portions 21a and 21b to have a width along the overlap portion Ya with respect to the overlap portion Ya of the belt-like nonwoven fabric 200. Attached in the direction Y, the separating line attaching part 62 attaches the perforated package separating line 24 in the width direction Y in parallel with the seal parts 21a, 21b between the seal parts 21a, 21b.

By means of the longitudinal closing device 50 and the width closing device 60, the lower side portion 20b corresponding to the bottom of the beverage extraction package 10B in the strip-shaped nonwoven fabric 200 is closed by the seal portion 21b, and the side portion 20c is closed by the seal portion 21c. Thus, the coffee powder C is filled at a height that allows it to be filled.
At that time, the coffee powder C for beverage extraction discharged from the discharge port 41a of the supply pipe 41 in the raw material supply device 40 is placed on the overlapping portion 20Z (housing portion 11a) formed between the overlapping surfaces of the strip-shaped nonwoven fabric 200. On the other hand, a predetermined amount is filled (see FIG. 12).

  In conjunction with the filling operation of the raw material supply device 40, the sealing operation of the longitudinal direction closing device 50 and the width direction closing device 60, and the attaching operation of the arc-shaped opening wire attaching device 70, the entire belt-shaped nonwoven fabric 200 is The beverage extraction packaging body 10B for one bag is sequentially transferred in the feeding direction Z by the pitch to be transferred, and the beverage extraction packaging body 10B filled with a predetermined amount of coffee powder C is continuously fed in the feeding direction Z.

Since the number of separation lines that allow separation of the upper side portion 20a and the side side portion 20c is reduced by one, the manufacturing process can be simplified and the manufacturing cost can be reduced.

  The beverage extraction packaging body 10B opened as described above leaves the unseparated lower side portion 20b and the bent side portion 20d in the bag body 11, and the arc-shaped opening side edge portion 12 in the bag body 11 is peeled off. The beverage extraction packaging body 10 </ b> B can be transformed into an opening shape having an upside down inverted cone shape (funnel shape) simply by pulling and opening in the direction of the arrow shown in FIG. 10.

  That is, when the upper side portion 20a and the side side portion 20c are separated along the arc-shaped opening line 25, the opening side edge portion 12 of the bag body 11 becomes an arc shape, so that the beverage extraction packaging body 10B has an upside down conical shape. It can open to the magnitude | size and shape corresponding to the opening part opened toward the upper direction of the cup 30 which has (refer FIG. 10).

  In addition, since the upper side portion 20a and the side side portion 20c are collectively separated along one continuous arc-shaped opening line 25, the separation and opening can be performed smoothly, and unexpected tears and tears are less likely to occur. The coffee powder C accommodated in the main body 11 can be opened more easily without flowing out.

  Subsequently, when the beverage extraction packaging body 10B deformed into the upside down inverted cone shape is loaded into the upside down inverted cone shape cup 30 shown in FIG. 7, the outer surface shape of the beverage extraction packaging body 10B and the inner surface shape of the cup 30 Since they substantially match each other, the beverage extraction packaging body 10B can be loaded into the cup 30 in a reasonably stable state.

  Thereby, when the cup 30 loaded with the beverage extraction packaging body 10B is placed on the cup 31, and when the hot water H is poured into the coffee powder C accommodated in the beverage extraction packaging body 10B from above, the beverage extraction It is possible to prevent the loading position of the packaging body 10B from being displaced, or to create a gap that prevents good extraction between the outer surface of the beverage extraction packaging body 10B and the inner surface of the cup 30.

  As a result, the hot water H can be passed almost uniformly through the coffee powder C contained in the beverage extraction packaging body 10B, and the coffee powder C is uniformly steamed to provide a fragrance containing components unique to the coffee powder C. Since the extract liquid CH which is high and rich can be extracted efficiently, the operation and effect substantially equivalent to those of the above embodiment can be achieved.

  In addition, although the example which attaches the arc-shaped opening line 25 beforehand to the strip | belt-shaped nonwoven fabric 200 developed in the width direction Y was demonstrated in the other example mentioned above, for example, the strip | belt-shaped nonwoven fabric 200 is folded in two with respect to the width direction Y.
