Then, the sliding blocks 37 and 39 are reciprocated from the state shown by the solid line in FIG. 3 to the direction AB as shown by the phantom line by the drive mechanism (not shown), and receive the ultrasonic horn 41a of the ultrasonic seal device 41. As shown in FIG. 7, it is sealed and cut by the roll device 41b to form the lower lateral seal portion Sb1.
Next, the tea T as an extract to be weighed by the weighing device 5 is poured into the charging chute 7, and the leading end portion of the packaging material S whose leading end is closed by the lower lateral seal portion Sb1 from the lower opening 7a. That is, it is accommodated in the filling part Bj.
Then, the packaging material S is sent at a pitch corresponding to the height dimension Ba of the tea bag B1.

  The rotation base 15 is rotated 90 degrees clockwise from the state shown in FIG. 3 to the state shown in FIG. 4. In this state, the sliding blocks 37 and 39 are shown by solid lines in FIG. As shown by the phantom line from the state shown in FIG. 7, the reciprocating operation is performed in the CD direction, and the ultrasonic horn 41a and the receiving roll device 41b of the ultrasonic sealing device 41 are sealed and cut as shown in FIG. The lateral seal portion Sb2 is formed and the tea bag B1 is completed and separated from the packaging material S. The tea bag B1 falls through the openings 15a and 17a, and is discharged to the outside through the discharge chute 19.

  Simultaneously with the formation of the lateral seal portion Sb2, the lateral seal portion Sb3 on the lower side of the next manufactured table bag B2 is formed. Then, the tea T weighed by the weighing device 5 is poured into the charging chute 7 and accommodated in the leading end portion of the packaging material S, ie, Bj, whose leading end is closed by the lower side seal portion Sb3 from the lower opening 7a. Is done. Then, the packaging material S is sent at a pitch corresponding to the height dimension Ba of the tea bag B. Also at this time, gathers Ga and Gb are formed on the packaging material S.

The portion Sb3 is turned 90 degrees, but the tea bag B1 and the tea bag B2 have substantially the same shape. Therefore, as shown in FIG. 5, when the tea bag B1 is turned upside down from the state at the time of manufacture, the state becomes exactly the same as the tea bag B2. As shown in the figure, the base end portion of the thread 49 having the tag 47 fixed to the tip portion is fixed to the lower side seal portion Sb1 side in the tea bag B1, and the upper side seal portion Sb4 side in the tea bag B2. The tea bag B1 and the tea bag B2 are exactly the same product in the state fixed to. The thread 49 with the tag 47 is fixed to the packaging material S in advance.

In the tea bags B1 and B2, gathers Ga and Gb are formed, and the lower horizontal seal portion Sb1 (Sb4) and the upper horizontal seal portion Sb2 (Sb3) are in a plane intersecting the vertical seal portion Sa. Since the angle is shifted by 90 degrees in the direction of rotation, a large volume can be obtained without increasing the vertical and horizontal dimensions. Therefore, a considerable amount of tea T can be accommodated without causing the inconvenience of not entering the pot.
In addition, since a large surface area can be obtained, tea T can be extracted efficiently and sufficiently.

  The tea bag B3 shown in FIG. 9 has a large height dimension B3a, and gathers Ga and Gb are formed on both left and right sides. Since the tea bag B3 is manufactured by the extraction bag manufacturing apparatus 1 and adopts the same manufacturing method as the tea bags B1 and B2, only the differences in the manufacturing method will be described, and the tea bag B1 and B2 will be used in the description. Quote the sign that was present.

Then, with the rotation base 15 fixed to the state shown in FIG. 4, the sliding blocks 37 and 39 together with the ultrasonic horn 41a and the receiving roll device 41b of the ultrasonic seal device 41 are shown in a solid line in FIG. It reciprocates in the CD direction as indicated by a virtual line. Thereby, the ultrasonic horn 41a and the receiving roll device 41b seal and cut the packaging material S to form the lateral seal portions Sb5 and Sb6, and the tea bag B3 is manufactured.
In forming the horizontal seal portion Sb6, the horizontal seal portion Sb5 of the tea bag B3 to be manufactured next is formed.

The tea bag B4 shown in FIG. 11 is the same as the tea bag B3 except that the height dimension B4a at the time of manufacture is smaller than the height dimension B3a of the tea bag B3. Moreover, the manufacturing method is the same as the manufacturing method of tea bag B3 except that the one-pitch feed dimension of the packaging material S is small.
However, the base end portion of the yarn 49 to which the tag 47 is fixed is fixed to the side on which the gathered Ga or gathered Gb is formed, and as shown in FIG. 11, the side on which the gathered Ga or Gb is formed is the upper side. .

The embodiment of the present invention has been described in detail above. However, the specific configuration is not limited to this embodiment, and the present invention can be changed even if there is a design change without departing from the gist of the present invention. included.
For example, only one of the gathers Ga and Gb may be formed. In this case, the tea bag is manufactured with one of the gather plates 13a and 13b removed.
