  Hereinafter, embodiments will be described in detail with reference to the drawings.

First Embodiment Referring to FIG. 1, a bag body 10 </ b> A includes a bag main body 11 and a dispensing unit 13 fixed to the bag main body 11.

  The bag body 11 is a flat bag having first and second flat portions 11a and 11b, and peripheral edges 11a1 and 11b1 thereof are sealed by heat sealing. The bag body 11 has a hypotenuse 11e connecting the ends of the apex 11c and the side 11d.

  Any laminated film may be used for the bag body 11. For example, a base material layer, an intermediate layer, and an innermost layer laminated from the outside are used.

  The substrate layer is preferably a film having excellent printability and further having impact resistance such as piercing strength and tensile strength. For example, a biaxially stretched film such as polyethylene terephthalate, polypropylene, polyamide, ethylene vinyl alcohol copolymer, or a single body or a laminate of a uniaxially stretched film is used. In order to impart oxygen or water vapor barrier properties to these, a material such as a metal such as aluminum or an inorganic oxide such as silicon oxide, or a material coated with polyvinylidene chloride is used. Also, paper or cellophane may be used.

  The intermediate layer is preferably a film having functionalities such as oxygen barrier property, water vapor barrier property, and tear property depending on the use of the bag. For example, a metal foil such as aluminum, the above-described deposited film, or a coat film is used.

  As the innermost layer, a film that can be heat-sealed by heat sealing is desirable. For example, unstretched films such as high-density polyethylene, low-density polyethylene, linear low-density polyethylene, and polypropylene are used. Furthermore, it is desirable that the material is the same as that of the pouring unit 13 in order to stick the pouring unit 13 by heat sealing.

  These films are bonded by a known method using an adhesive, a heat-fusible resin, or the like.

  Further, the bag body is not limited to the flat bag of the bag body 11, and a standing pouch having a bottom material or the like may be used.

  The bag body 10 </ b> A includes a dispensing unit 13 that is connected to the bag body 11 and protrudes from the oblique side 11 e of the bag body 11. The dispensing unit 13 uses a resin such as polyethylene or polypropylene and is molded by injection molding. The dispensing unit 13 includes two rectangular first and second sheets 13b and 13c each having an upper side 13d, a left side 13e, a right side 13f, and a lower side 13g, and the first and second sheets 13b and 13c overlap each other. Has been. A vertex 13a formed by the upper side 13d and the left side 13e constitutes a corner 10b of the bag body 10A.

  The dispensing unit 13 has a right side 13 f and a lower side 13 g as peripherals positioned in the bag body 11. The right side 13f extends obliquely with respect to the upper side 13d. The lower side 13g extends obliquely with respect to the left side 13e. The right side 13f and the lower side 13g intersect each other to form a diagonal point 13h. A diagonal line L2 connecting the vertex 13a and the diagonal point 13h bisects the dispensing unit 13.

  In the dispensing unit 13, the first and second sheets 13b and 13c are bonded to each other on the upper side 13d and the left side 13e. In addition, the dispensing unit 13 is attached to the inner surfaces of the first and second flat portions 11a and 11b of the bag body 11 by heat sealing at the portions where the first and second sheets 13b and 13c overlap the bag body 11, respectively. They are combined and integrated with the bag body 11.

  The dispensing unit 13 includes a zip 15 disposed inside the bag body 11. For example, the zip 15 is bent on the diagonal line L2 and positioned parallel to the right side 13f and the lower side 13g. The zip 15 includes male and female zips 15a, 15b that bite each other. The male and female zips 15a and 15b are integrally formed on the inner surfaces of the first and second sheets 13b and 13c, respectively. The male and female zips 15a and 15b are engaged to seal the bag body 10A.

  The dispensing unit 13 may be provided with a knob 14 disposed outside the bag body 11 so as to protrude outward. The knob 14 includes first and second knobs 14 </ b> A and 14 </ b> B that penetrate the flat portions 11 a and 11 b of the bag body 11, respectively. By pulling the first and second knobs 14A and 14B toward the outer side of the bag body 10A, the bite of the male and female zips 15a and 15b of the zip 15 is released, and the bag body 10A can be easily opened.

  The dispensing unit 13 may have an opening 13j for separating the portion connected to the bag body 11 and the apex 13a. The opening portion 13j is positioned in alignment with the hypotenuse 11e of the bag body 11. The unsealing part 13j extends in a straight line perpendicular to the diagonal line L2, and reaches the upper side 13d and the left side 13e. For example, the opening 13j is formed by reducing the thickness of the first and second sheets 13b and 13c, so that the portion connected to the bag body 11 and the apex 13a can be easily separated. The unsealed portion 13j may form a so-called rough surface portion made of an aggregate of fine holes.

  In addition, the pouring unit 13 may form a notch as a tear start part on the upper side 13d and the left side 13e and on the extension of the opening part 13j. A combination of these may also be used.

  On the inner or outer surface of the first and second sheets 13b, 13c of the dispensing unit 13, a folding line that coincides with the diagonal line L2 may be formed between the vertex 13a and the diagonal point 13h. The fold line is formed, for example, by reducing the thickness of the first and second sheets 13b and 13c. When a force is applied to the upper side 13d and the left side 13e from the left and right sides of the dispensing unit 13, the first and second sheets 13b and 13c are bent with respect to the fold line, and the fold line becomes a ridge line. In other words, the spout 13k of the opening 13j can easily form a wide rectangular opening state due to the folding line.

  The bag body 10A is positioned so as to be displaced from the dispensing unit 13, and includes U-shaped first and second depressions 17A and 17B formed on the top side 11c and the side side 11d. The first and second depressions 17A and 17B are positioned adjacent to the right side 13f and the lower side 13g. The hollow portions 17A and 17B are arcuate arch portions that connect the first and second leg portions 17a and 17b and the first and second leg portions 17a and 17b that extend vertically inward from the top side 11c and the side side 11d. 17c. The first leg 17a is closer to the right side 13f and the lower side 13g than the second leg 17b, respectively. The depressions 17A and 17B are perpendicular to the diagonal line L2 in which the lines connecting the two leg parts 17a and the two leg parts 17b respectively connect the vertex 13a and the diagonal point 13h and bisect the dispensing unit. If it exists, since the force of a finger is applied perpendicularly to the diagonal L2 when the depressions 17A and 17B are gripped by a finger, it is easy to maintain a rectangular wide opening state of the spout 13k, which is preferable.

  Next, a method of using the bag body 10A will be described.

  The upper end portion of the bag body 10A composed of the first side 11c of the bag body 11 and the upper side 13d of the dispensing unit 13 is opened, and the contents are filled from the upper end portion. After filling, the upper end portion is bonded by heat sealing, and the bag body 10A is sealed.

  When opening the bag body 10A, the top part of the extraction unit 13 as the corner 10b of the bag body 10A is cut out along the opening part 13j to form a spout 13k (see FIG. 2). When the knobs 14A and 14B are pulled outward, the bite between the male zip 15a and the female zip 15b of the zip 15 is released. Next, referring to FIG. 2, the bag body 10 </ b> A is gripped by placing a finger on the first and second hollow portions 17 </ b> A and 17 </ b> B. By grasping these fingers toward the inside of the bag body 10A, the spout 13k of the spout unit 13 spreads in a rectangular shape, and a wide open state can be maintained. Further, the bag body 10A does not slide down from the fingers.

  The bag body 10A is tilted and the contents are poured out from the spout 13k. After pouring, the bag body 10A can be resealed by biting the male zip 15a and the female zip 15b with each other.

Second Embodiment Referring to FIG. 3, the bag body 10B is characterized by the first and second depressions 18A and 18B, and the other configurations are the same as the bag body 10A of the first embodiment. is there.

  The V-shaped first and second depressions 18A and 18B extend in a direction perpendicular to the diagonal line L2 that connects the apex 13a and the diagonal point 13h and bisects the dispensing unit 13. The first and second depressions 18A, 18B have first and second legs 18a, 18b that extend obliquely with respect to the top side 11c and the side 11d. The first and second leg portions 18 a and 18 b approach each other toward the inside of the bag body 11. The first leg portion 18a is closer to the dispensing unit 13 than the second leg portion 18b. The first leg portion 18a is parallel to a diagonal line L2 connecting the vertex 13a and the diagonal point 13h. The second leg portion 18b is perpendicular to the diagonal line L2 connecting the vertex 13a and the diagonal point 13h.

  According to this bag body 10B, a finger is inserted between the first and second leg portions 18a, 18b. When a force is applied to the first leg portion 18a with a finger, a force is applied perpendicularly to the diagonal line L2 connecting the vertex 13a and the diagonal point 13h, so that it is easy to maintain the rectangular wide opening state of the spout 13k.

  In addition, the said embodiment can be changed in the range of the meaning of this invention. For example, the depressions 17 and 18 are not limited to the U-shape and V-shape described above, and may be any shape as long as they function as means for maintaining the open state. Moreover, even if it is the position, a part or all of the extraction unit 13 may overlap.

  In addition, the heat seal described is not limited to a heat sheet, and any method may be used as long as the seal can be performed using a seal using an adhesive or a seal using a hot melt method. Absent.
