  • a gas introduction port 141 for feeding a gas (air) into each of the gas enclosing portions is provided in communication with the third posterior gas enclosing portion 137 , rearward of the spout 200 .
  • each gas enclosing portion expands and the rigidity of the packaging bag 100 increases. Subsequently, a base portion (region indicated by M in the drawing) of the gas introduction port 141 is sealed, completing the third posterior gas enclosing portion 137 and completing the enclosure of a gas in each gas enclosing portion.
  • the position of the gas introduction port 141 may be on a top surface, or may be on a body portion or a bottom surface.
  • the gas may be enclosed in the gas enclosing portion by feeding the gas from the gas introduction port between two films as in FIG. 4 , or by providing a hole in a portion of the gas enclosing portion, blowing in the gas through the hole and, once enclosure is completed, closing the hole.
  • a notch portion 151 cut inward is provided in a region below the left side seal portions 104 , 106 and, similarly, a notch portion 152 cut inward is provided in a region below the right side seal portions 105 , 107 .
  • the gas enclosing portions (first side gas enclosing portion 131 and second side gas enclosing portion 132 ) curve toward the anterior surface side, making the packaging bag 100 easier to hold.
  • a slit may be provided instead of the notch portion.
  • the first posterior gas enclosing portion 135 , the third posterior gas enclosing portion 137 , and the second posterior gas enclosing portion 136 are provided surrounding a rear side of the spout 200 .

  • the gas enclosing portions in communication with each other are formed extending in the three directions (branching into three portions) of frontward, downward, and rearward. This increases the rigidity for maintaining the external shape of the packaging bag 100 and thus, when the contents are dispensed from the spout 200 , the spout 200 is free of wobbling even when the packaging bag 100 is tilted, making it easy to stably dispense the contents from the spout.
  • the anterior front top seal portion 111 protrudes frontward, making it possible to provide the top sheet 110 with inclination.
  • the anterior front top seal portion 111 does not enclose a gas.
  • the top sheet 110 is urged to incline toward the anterior side, and thus the spout 200 also inclines toward the anterior side following the inclination of this top sheet 110 .
  • an inclination angle of the top sheet 110 can be set to any inclination angle.
  • displaying the side with the spout 200 as the back surface and the back sheet 102 side as the front surface means that the upright back sheet is visible to a customer.
  • Printing a design indicating product contents or the like on the back sheet 102 expands the display area and can draw the attention of a consumer.
  • FIG. 5 is a perspective view from a front side of the pouch 1 A
  • FIG. 6 is a plan view from the front side of the pouch 1 A before introducing a gas into the gas enclosing portions.
  • the basic configuration of the pouch 1 A in the present embodiment is the same as that of the pouch 1 in the first embodiment described above.
  • the difference is that, in the pouch 1 A, the spout 200 is provided on the fold line S 1 . This allows the spout 200 to be positioned further frontward than in the pouch 1 in the first embodiment described above, and thus the contents can be dispensed more easily.
  • the other effects are the same as those of the pouch 1 in the first embodiment described above.
  • FIG. 7 is a perspective view from a front side of the pouch 1 B.
  • the basic configuration of the pouch 1 B in the present embodiment is the same as that of the pouch 1 in the first embodiment described above. The difference is that, in the pouch 1 , in a lower region of the packaging bag 100 , the notch portion 151 cut inward is provided in the region below the left side seal portions 104 , 106 and, similarly, the notch portion 152 cut inward is provided in the region below the right side seal portions 105 , 107 , whereas, in the pouch 1 B of the present embodiment, the notch portion 151 and the notch portion 152 are not provided, and the left side seal portions 104 , 106 and the right side seal portions 105 , 107 are provided extending to the bottom edge. According to this configuration, sealability in the lower region of the packaging bag 100 can be further improved. The other effects are the same as those of the pouch 1 in the first embodiment described above.
  • FIG. 8 is a perspective view from a front side of the pouch 1 C.
  • the basic configuration of the pouch 1 C in the present embodiment is the same as that of the pouch 1 in the first embodiment described above. The difference is that, in the case of the pouch 1 C, the first side gas enclosing portion 131 and the second side gas enclosing portion 132 do not extend to a bottom edge region of the packaging bag 100 and, when viewed in the height direction of the packaging bag 100 , stop at a position higher than half of the height of the packaging bag 100 [(H 1 )/2 ⁇ H 2 ]. Further, the third posterior gas enclosing portion 137 is not provided.
  • this configuration is suitable when only increasing the rigidity around the spout 200 is sufficient.
  • this configuration is suitable in a case in which the volume of the contents is small.
  • the other effects are the same as those of the pouch 1 in the first embodiment described above.
  • FIG. 9 is a perspective view from a front side of the pouch 1 D.
  • the basic configuration of the pouch 1 D in the present embodiment is the same as that of the pouch 1 C in the third embodiment described above.
