  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective plan view of a bag container according to Embodiment 1 of the present invention. In FIG. 1, the main body of the bag container 1 is a pouch for beverages constructed by superimposing two front and back films and sealing the periphery thereof. Hereinafter, the left and right side seal portions of the bag container 1 are referred to as side seal portions 2 and 3, the upper side seal portion is referred to as the upper seal portion 4, and the lower side seal portion is referred to as the lower seal portion 5.

  A content accommodating portion 6 which is a bag-like sealed space is formed in a non-sealed portion at the center of both films. In the vicinity of the upper corner of the main body 1, an outflow path 7 is formed which is a non-seal portion that communicates with the content container 6 and is narrower than the content container 6.

  The capacity | capacitance of the content accommodating part 6 assumed in a present Example is about 50 ml-2000 ml. The front and back films are made of synthetic resin (PE (polyethylene), PET (polyethylene terephthalate), PVC (polyvinyl chloride), PMMA (polymethyl methacrylate), PP (polypropylene), PA (nylon), PS (polystyrene), A single-layer or multi-layer sheet selected from PMP (polymethylpentene), PVDC (polyvinylidene chloride), PC (polycarbonate), and the like, a synthetic resin-processed aluminum foil, and a sheet of synthetic resin-processed paper can be used. For example, it can be a three-sided bag or a standing pouch prepared by welding the periphery of a multilayer synthetic resin sheet, synthetic resin processed aluminum foil, or synthetic resin processed paper.

  In the side seal portion 2 on the side where the outflow passage 7 of the main body 1 is formed, a notch portion 8 is formed in a cut shape. The notch portion 8 is a V-notch, and the corner portion on the open end side is rounded in an arc shape.

  The upper seal portion 4 is formed with a wide portion facing the side seal portion 2 across the outflow path 7. The wide portion of the upper seal portion 4 is referred to as a land seal portion 4a.

  A narrow and narrow non-seal portion is formed from an end position facing the notch portion 8 of the land seal portion 4a toward the inside of the land seal portion 4a. Call. The cutting guide non-seal part 9 is formed along a virtual opening line (referred to as “virtual opening line 10”). In this embodiment, the cutting guide non-seal part 9 is bent in an arc from the side to the bottom. It is formed in a different shape. The width of the cutting guide non-seal portion 9 is 0.5 to 10 mm, and plays a role of guiding the breaking direction so as not to deviate from the virtual opening line 10 when the film is broken. That is, since the cut-out guide non-seal portion 9 is not welded to the front and back films, the strength is weaker than the welded land seal portion 4a. Therefore, when it fractures | ruptures from the notch part 8 toward the cutting guide non-seal part 9, it breaks along the cutting guide non-seal part 9 weaker than the land seal part 4a fractures.

  Before the contents are sealed in the bag container 1, the section other than the land seal part 4 a of the upper seal part 4 (hereinafter referred to as “post-injection seal part 4 b”) in the sealed part with hatching in FIG. 1. ) Is left open without welding. And after injecting the contents (beverage) from the post-injection seal part 4b to the content storage part 6, the post-injection seal part 4b is welded and sealed. Thereby, the contents can be enclosed in the bag container 1.

  FIG. 2 is a perspective plan view showing a state in which the bag container of FIG. 1 is opened. FIG. 2 shows a state in which the bag container 1 is broken along the virtual opening line 10 and bent along the folding line 11 (see FIG. 1). By bending in this way, the outflow path 7 protrudes upward, so that the protruding portion can be held in the mouth and drinks stored in the bag container 1 can be drunk (sucked out from the outflow path 7). Alternatively, the bag container 1 can be pushed by hand to push the beverage into the outflow passage 7 for drinking).

  The length of the outflow passage 7 is preferably 5 mm to 50 mm from the viewpoint of ease of drinking.

  Since the notch portion 8 has a rounded corner at the open end, it is possible to prevent an accident in which the mouth is cut at the corner of the notch portion 8 when the protruding portion is held in the mouth. In other words, normal V notch (V notch which is not chamfered), line notch, U notch, Komagata notch of the pentagonal shogi, there is a concern that the corner will stand up and cut the lips as a drinking mouth, but it was rounded By adopting a V-notch configuration, the mouth becomes round and safety is enhanced.

  In addition, in order to make a fracture | rupture easier, you may provide a half cut line along the cutting guide non-seal part 9 together.
