The upper edge portion and the side edge portion of the front and back trunk sheets 11 and 11 are joined to each other by heat fusion or the like to form an upper edge joint portion 21 and a side edge joint portion 22. A bottom edge joint portion 23 is formed by joining a peripheral edge portion of a bottom sheet 12 (not shown) to a lower edge portion of the bottom sheet 11 by heat fusion or the like.
Note that the bag 10 fills the upper edge opening of the body sheet 11 after the formation of the side edge joints 22 and the bottom edge joints 23 of the body sheet 11 and the bottom sheet 12 with a filling opening (a spout opening portion to be described later). 3
Fill the contents as 1) and then connect the upper edge joint 2 as described above.
1 is formed and the filling port is sealed. The bag 10 has a spout expected portion 31 at the center of the upper edge joint portion 21. The spout expected portion 31 has a pointed shape protruding outward in the longitudinal direction of the bag 10 at the center of the upper edge joint portion 21, and the trunk sheet 1 of the bag 10 is formed.
1 is provided with a cutout display line 31A, and the spout 31B is cut by cutting the upper edge joint 21 along the cutout display line 31A.
Can be formed. The bag 10 is provided with upper edge joints 21 and overhanging portions 41, 41 that are continuous from the side edge joints 22 on both sides of the expected spout portion 31 of the upper edge joint 21, and the upper edge joints 21 and the side edges are provided. A substantially rectangular outline is formed by the joint portion 22 and the overhang portion 41. The overhang 41 is an extension from the upper edge joint 21 and the side edge joint 22 of the front and back trunk sheets 11. Overhang 4
1 is provided with a substantially square hole-shaped perforated portion 42 together with the outer edge of the upper edge joint portion 21, and the cutting start portion 32 of the upper edge joint portion 21 which is the end of the cut display line 31A has a V-notch shape. A part of the perforated portion 42 is formed. The bag 10
The upper edge joint 21 is cut along the cut display line 31A from the cutting start portion 32 to form a spout 31B, and the cut upper edge joint 21 and the overhanging portion 4 continuous therewith are formed.
A handle 43 is formed by 1 and 41. When using the bag 10,
As shown in FIG. 2, one finger is inserted into the handle 43 to grasp the handle 43, the other hand supports the side surface of the bag 10 from below, and the content liquid is poured out from the spout 31B. According to the present embodiment, the following operations are provided. At the time of pouring, the handle 43 is formed beside the spout 31B of the bag 10, so that the user can easily hold the bag 10 by using the handle 43, and the user can hold the bag 10 with a constant holding regardless of the person. And easier to pour out. The handle 43 can be formed simultaneously with the formation of the spout 31B, the band-like handle 43 that does not hurt the user's finger can be easily formed, and the handleability of the bag 10 can be improved. The spout expected portion 31 of the bag 10 has a pointed shape protruding outward from the bag 10, so that the spout 31
The flow path toward B is pointed to form a stable pouring trajectory, so that the pouring property can be improved and the pouring port 31B can be inserted into the mouth of the bottle, so that liquid spillage can be prevented. Since both sides sandwiching the expected spout 31 of the bag 10 are formed as the overhanging portions 41, when filling the bag 10 with the expected spout 31 as the filling opening, the same as the filling opening (the expected spout 31). Hold both side overhangs 41 at the level with the chucks on both sides,
After the filling, the filling port can be sealed with a heat seal bar or the like while the overhanging portions 41 are held by the chucks on both sides. Since the same level as the filling port 31B is gripped by the chucks on both sides, the filling level of the content liquid into the bag 10 can be set to near the filling port, and the filling amount can be reduced. Further, the heat seal bar can be positioned at the filling port without being hindered by the chuck, and the sealing workability can be improved. The bag 10A of FIG. 3 is substantially different from the bag 10 of FIGS. 1 and 2 in that the overhang 41 is not provided with a perforated portion 42 and the cut display line 31A extends to the outer edge of the overhang 41. A slit 52 (FIG. 3 (A)) extending along the spout forming direction (lateral direction) is cut out at the extending end thereof as a cutting start part 51 for the upper edge joint part 21 and the overhang part 41. It is in. By cutting the upper edge joint portion 21 and the overhang portion 41 from the cutting start portion 51 along the cut display line 31A, a spout 31B is formed, and the cut upper edge joint portion 21 and the continuous overhang are formed. A handle is formed by the parts 41 and 41. As the cutting start portion 51 of the bag 10A, FIG.
A slit 53 as shown in FIG. The slit 53 has a substantially L shape along both directions of a spout forming direction (horizontal direction) and a direction perpendicular to this (vertical direction). Thereby, the handle is provided in the substantially L-shaped slit 5 provided on the outer edge of the bag 10A.
3, the upper edge joint 21 and the overhang 41 are cut not only in the spout forming direction (horizontal direction) but also in a direction (vertical direction) perpendicular to the spout forming direction (horizontal direction) and are cut open two-dimensionally. The cut-out portion can be used as a wide finger insertion portion, and the grip can be easily held.
