Is provided. The width-direction length W ₃₀ of the scraped gusset portion 30 is preferably about 10% to 50% of the width-direction length W of the pouch container 10 from the viewpoints of scraping property, take-out property of the powder 100, and the like. % To about 40% is more preferable (see FIG. 1).

  The scraped gusset portion 30 has a first end portion 31 that is one end in the width direction joined to the front and back sheets by the side seal portion 22 from the viewpoint of ensuring rigid stability and improving the scrapability. It is suitable. And the 2nd end part 32 which is the other width direction edge part of the scraping gusset part 30 is utilized for scraping. That is, the measuring spoon 101 is pressed against the second end portion 32.

  As shown in FIG. 4, the cut-off gusset portion 30 expands on the second end portion 32 side until the front half portion 30a and the back half portion 30b are substantially parallel. An upper surface 33 having a substantially triangular shape is formed in the chopped gusset portion 30 that is largely developed. The triangle on the upper surface 33 is an inclined isosceles triangle with the apex P1 in contact with the side seal portion 22 as the lower end and the apexes P2 and P3 in contact with the joint portion 27 as the upper end, and the second end portion 32 is the upper side. As described above, the developed scraped gusset portion 30 is stably supported by the portions corresponding to the vertices P1 to P3 of the upper surface 33.

As described above, the protective gusset portion 40 is provided between the other end in the container width direction and the gusset opening 28, and covers a part of the filling portion 14 along the container width direction from the other end in the container width direction. It is provided as follows. The other end of the protective gusset 40 is joined to the front and back sheets by the side seal part 22, and the upper half of each of the protective gussets 40 is joined to the front and back sheets by the joint 27. The width direction length W ₄₀ of the protective gusset portion 40 is set to a length at which the second end portion 42 is positioned above the chuck 16 at least in a state where a non-joining region described later is bent upward. The length is set such that the second end portion 42 protrudes from the upper end of the pouch container 10 (see FIGS. 1 and 5). Note that the width direction length W ₂₈ of the gusset opening 28 is preferably at least 20% or more of W. For example, W ₃₀ is determined according to W ₄₀ and W ₂₈ .

  The protective gusset part 40 is an upper part of the front half part 40a and the back half part 40b from the edge part of the gusset opening 28 (that is, the second end part 42) which is one end part in the width direction toward the other end side in the container width direction. Each has a notch 44 that is a non-bonded portion formed in each of the two. The “upper part” of the gusset half (the front half 40a and the back half 40b) is more than the middle between the crease line 26 formed along the lower end thereof and the joint 27 formed along the upper end thereof. It means the upper side, and preferably, a notch 44 is formed in the vicinity of the joint portion 27. In the present embodiment, the downward gusset sheet 25 is provided over the entire width, but by inserting the notch 44, a portion bonded to the front and back sheets and a non-bonded region that is not bonded can be formed. The non-joining region can be bent upward. That is, the non-joining portion means the upper edge portion of the non-joining region.

  The cut 44 is formed in a straight line from one end on the gusset opening 28 side to the other end on the side seal portion 22 side. The other end of the cut 44 is preferably provided at a position away from the inner edge of the side seal portion 22 by a predetermined length (see FIG. 6). That is, it is preferable not to form the cut 44 within a predetermined length from the inner edge of the side seal portion 22. Thereby, when taking out powder 100 using protective gusset part 40, it can prevent that powder 100 falls out between between protection gusset part 40 and the front and back sheets. The other end of the notch 44 is located at the second end portion 42. The predetermined length is preferably a length corresponding to the vertical length L2 from the crease line 26 to the cut 44, and the length L1 of the cut 44 is from the second end 42 to the inner edge of the side seal portion 22. The length is obtained by subtracting L2 from the length.

  A crease line 45 is formed in the protective gusset portion 40 by bending a portion located below the notch 44, that is, the non-joining region upward. That is, the non-joining region is a portion surrounded by the notch 44 and the crease line 45 and is formed from the one end in the width direction of the protective gusset portion 40 over a predetermined width. In the present embodiment, the predetermined width can be changed as appropriate by adjusting the length of the cut 44, for example. Note that the crease line 45 may be formed in advance so that the folding operation of the protective gusset portion 40 is smooth. In the following description, it is assumed that the crease line 45 is formed in advance.

  The crease line 45 is preferably formed from the other end P4 of the notch 44 to an intersection P5 between the crease line 26 and the inner edge of the side seal portion 22 (see FIG. 6). According to P4 formed at the above position, the angle α formed between the crease line 45 and the inner edge of the side seal portion 22 is approximately 45 °, and a smooth folding operation of the non-joining region is possible. When the angle α is approximately 45 °, the non-bonded region is in a state along the vertical direction when bent upward and the take-out property of the powder 100 is improved.

  As shown in FIGS. 5 to 7, when the non-bonded region of the protective gusset portion 40 is folded upward by inverting the fold line 26, the second end portion 42 extends upward beyond the position of the chuck 16. Is covered by the non-bonded area. In the non-bonded region, the upper surface 43 of the front half 40a and the back half 40b face each other in a state before being bent, but the crease line 26 is reversed in a state of being bent upward and along the vertical direction. Then, the lower surfaces 46 face each other. That is, the scraped gusset part 30 is folded back so that the upper surface 43 faces the chuck 16 side at the crease line 45. Then, the powder 100 is taken out through the lower surface 46.

Next, an example of a method for manufacturing the pouch container 10 will be described with reference to FIG.
FIG. 8 schematically shows a process of laminating long sheets of sheet materials and forming each seal portion in the manufacturing process of the pouch container 10. Here, let the longitudinal direction of a long body be MD direction, and let the width direction of a long body be TD direction.

  As shown in FIG. 8, first, a sheet constituting the top sheet 11, the back sheet 12, the bottom gusset sheet 13, and the chuck 16 (for example, a first sheet with a convex strip and a second sheet with a concave strip) ) And long bodies of the downward gusset sheet 25 (hereinafter, referred to as long bodies 11z, 12z, 13z, 16z, and 25z) are prepared and stacked on each other. The long body 25z is formed with a gusset opening 28 by leaving a connecting portion 29 by a die cut roll or the like, and a cut 44 and a crease line 45 are formed. The long body 16z is laminated in a state in which the ridges of the first sheet and the ridges of the second sheet are fitted.

  In the laminating process of each long body, first, the long body 11z and the long body 12z are overlapped, and the long body 13z is inserted into the lower ends of the long body 11z and the long body 12z. The long bodies 16z and 25z are inserted into the upper part of the long body 12z, respectively. At this time, the long body 25z is inserted on the lower end side of the long body 16z. Note that a notch 17 and the like are formed in a later step in a portion on the upper end side of the long body 16z.

  Each sealing part is formed in the elongate body which passed through the lamination process at the heat sealing process. In the heat sealing step, the predetermined portion is heat sealed along the lower edge of the long body and the TD direction. Here, the lower edge of the elongated body is a portion that becomes the lower edge of the pouch container 10, and the predetermined portion is a portion that becomes a side edge of the pouch container 10. That is, by this heat sealing process, the lower edge seal portion 21 and the side seal portion 22 (wide seal portions for two containers) are formed.

  In the heat sealing step, the long bodies 16z and 25z are further joined to the long body 11z and the long body 12z, respectively. A joint 27 along the MD direction is formed at the upper end of the long body 25z. In addition, the side seal portion 22 is formed in a state where the first end portion 31 of the cut-off gusset portion 30 and the first end portion 41 of the protective gusset portion 40 are arranged at the side edge of the pouch container 10. Accordingly, the first end portions 31 and 41 are fixed to the top sheet 11 and the back sheet 12.

  Then, the said elongate body is cut along the virtual line X of the side seal part 22, for example using a die cut roll etc., and it divides | segments into each container size. At this time, the notch 17 can be formed in the side seal portion 22. Then, after filling the powder 100 from the upper end of the container, the upper edge seal portion 20 is formed, whereby the pouch container 10 filled with the powder 100 shown in FIG. 1 is obtained.

  Next, the action and effect of the pouch container 10 will be described in detail with further reference to the manner in which the powder 100 shown in FIGS. 9 and 10 is scraped off and the manner in which the powder 100 is taken out with the take-out port 18 directed vertically downward.

  When the powder 100 is taken out from the filling part 14, the takeout port 18 is formed using the notch 17, and then the chuck 16 is opened to open the takeout port 18. And by opening the taking-out port 18 largely, in the upper part of the container, the front and back sheets are separated from each other, and the downward gusset sheet 25 is developed. In the cut-off gusset portion 30, the first end portion 31 side is not expanded, but on the second end portion 32 side, for example, the front half portion 30a and the back half portion 30b are formed in a substantially parallel plate shape. expand. An inclined substantially triangular upper surface 33 is formed with the apex P1 in contact with the side seal portion 22 as the lower end and the apexes P2 and P3 in contact with the joint portion 27 as the upper end (see FIG. 4).

  As shown in FIG. 9, when the cut-off gusset portion 30 is deployed, the dish portion of the measuring spoon 101 with the powder 100 placed on the first end portion 31 can be pressed. Then, the excess powder 100 can be scraped off by pulling the measuring spoon 101 upward while pressing the dish portion against the second end portion 32. In this way, the amount of the powder 100 per cup of the measuring spoon 101 can be made constant, and simple weighing becomes possible. Since the cut-off gusset portion 30 is stably supported at the portions corresponding to the vertices P1 to P3, the cut-off gusset portion 30 is difficult to bend when the measuring spoon 101 is pressed against it, and good operability can be realized. .

  When the amount of the powder 100 in the filling portion 14 is reduced, it is difficult to scoop out using the measuring spoon 101, and thus the powder 100 is taken out using the protective gusset portion 40. Alternatively, when the powder 100 is taken out in large quantities, the powder 100 can be taken out from the beginning using the protective gusset portion 40. Specifically, the second end portion 42 side of the non-joined region surrounded by the notch 44 and the crease line 45 is lifted upward, and the crease line 26 is set so that the upper surface 43 faces the front and back sheet sides at the crease line 45. By reversing and turning back, the non-bonded region extends in the vertical direction, the second end 42 extends from the upper end of the container, and the chuck 16 is covered with the non-bonded region (see FIG. 7 and the like).

  As shown in FIG. 10, when the take-out port 18 is tilted vertically downward, more specifically, when the second end portion 42 of the folded protective gusset portion 40 is tilted vertically downward, the powder 100 moves along the wall surface of the container. Slide down. At this time, the powder 100 is taken out through the lower surface 46 of the protective gusset portion 40. Although the powder 100 passes over the chuck 16, the chuck 16 in the portion through which the powder 100 passes is covered with the non-bonded region of the protective gusset portion 40, so that the powder 100 does not adhere to the chuck 16. The powder 100 can be taken out smoothly. In addition, since the junction part 27 is formed in the upper end of the protective gusset part 40 along the width direction, the powder 100 does not pass between the protective gusset part 40 and the front and back sheets and is not taken out.

  As described above, according to the pouch container 10, the powder 100 can be weighed using the scraped gusset portion 30 and the powder 100 can be taken out using the protective gusset portion 40. By using the protective gusset portion 40, the powder 100 does not adhere to the chuck 16 even when the powder 100 is taken out with the take-out port 18 vertically downward and along the wall surface of the container. The seal 16 can be kept hygienic without impairing the sealing performance.

FIG. 11 shows a pouch container 10 x which is a modification of the pouch container 10.
As shown in FIG. 11, the protective gusset portion 40x of the pouch container 10x has a joint portion 47 with the front and back sheets along a portion where a crease line 45x is formed when the non-joint region is folded upward. This is different from the protective gusset 40 of the pouch container 10 in that respect. The joint portion 47 extends from the other end P4 of the notch 44 along the intersection P5 between the crease line 26 and the inner edge of the side seal portion 22 and into a substantially triangular region in front view that is continuous with the side seal portion 22 and the joint portion 27. Is formed. In this case, since the non-joining region of the protective gusset part 40x is bent along the joint part 47, it is not necessary to form the crease line 45 in advance. That is, it can be said that the crease line 45 x is formed by the joint portion 47. According to this configuration, the powder 100 can be prevented from entering and collecting between the protective gusset portion 40x and the front and back sheets.

<Second Embodiment>
The configuration of the pouch container 50 according to the second embodiment will be described with reference to FIGS. Here, the same components as those in the first embodiment are denoted by the same reference numerals, and redundant description is omitted.

  As shown in FIG. 12, the pouch container 50 is different from the pouch container 10 in that the scraped gusset portion 30 is not provided. In the downward gusset sheet 55, only the protective gusset portion 60 is formed on the other end side in the width direction, and a wide gusset opening 58 is formed on one end side in the width direction. Also in this case, the downward gusset sheet 55 is provided over the entire width of the container, and a band-shaped joint portion 57 is formed over the entire width.

  The protective gusset part 60 has the same configuration as the protective gusset part 40x of the pouch container 10x. Note that the width of the protective gusset portion 60 can be set longer because the scraped gusset portion 30 does not exist.

FIG. 13 shows a pouch container 50x which is a modification of the pouch container 50. FIG.13 (b) is a figure which shows the BB sectional view of (a).
As shown in FIG. 13, the downward gusset sheet 55x of the pouch container 50x is not provided over the entire width of the container, but is provided from the other end side in the container width direction to the vicinity of the center portion. Different from the downward gusset sheet 55. The entire downward gusset sheet 55x constitutes a protective gusset portion 60x, and does not have the belt-like joint portion 57 along the width direction.

  The protective gusset portion 60x (downward gusset sheet 55x) has the other end in the width direction joined to the front and back sheets by the side seal portion 22 and the joining portion 47. That is, the front side half 60xa and the back side half 60xb are joined to the front and back sheets only at the other end in the width direction and the vicinity thereof, respectively, and the protective gusset part 60x extends from the one end in the width direction to the joint 47. It has a joined portion and a non-joined region.

<Third Embodiment>
With reference to FIGS. 14-16, the structure of the pouch container 70 which is 3rd Embodiment is demonstrated. Here, the same components as those of the above-described embodiment are denoted by the same reference numerals, and redundant description is omitted. In the present embodiment, the cut-off gusset portion 30 and the protective gusset portion 40 are not formed in the unopened state, but the reference numerals 30, 40 are also given to the portions that become the gusset portions.

  As shown in FIGS. 14 and 15, the pouch container 70 is different from the pouch container 10 in that a downward gusset sheet 75 is provided to cover the entire area on the filling portion 14 in an unopened state. As shown in FIG. 16, the downward gusset sheet 75 is formed with a gusset opening 28 along with the opening of the take-out port 18, and has an opening auxiliary portion for forming the gusset opening 28. For this reason, the downward gusset sheet 75 at the time of manufacture has high rigidity and excellent transportability.

  The opening auxiliary portion has perforation lines 76a and 76b formed so as to intersect with the crease line 26, and a perforation line 77 formed so as to intersect with the perforation lines 76a and 76b. It is preferable that the perforation lines 76 a and 76 b and the perforation line 77 are substantially orthogonal to each other, and the perforation line 77 is formed along the crease line 26. As an opening auxiliary | assistant part, you may use a half cut line instead of a perforation line or with a perforation line.

  Further, the downward gusset sheet 75 is provided with a point seal portion 79 that joins the lid portion 78 and the front and back sheets to the lid portion 78 divided by each perforation line. The lid portion 78 is a portion corresponding to the portion that becomes the gusset opening portion 28 (the portion with mesh hatching in FIG. 15), and is a non-deployment portion that is fixed to the front and back sheets by the point seal portion 79 and does not unfold. .

  Note that a cut 44 and a crease line 45 are formed in the protective gusset portion 40 (the portion that becomes the protective gusset portion 40). The protective gusset portion 40 is provided between the perforation line 76b and the other end in the container width direction, and is formed on each of the front half 40a and the back half 40b from the perforation line 76b toward the other end in the container width direction. A cut 44 is provided. Alternatively, a perforation line or a half cut line for forming the cut 44 may be formed instead of the cut 44.

  As shown in FIG. 16, by opening the take-out port 18, the downward gusset sheet 75 is cut at each perforation line that separates the lid portion 78 and each gusset portion using the force acting on the downward gusset sheet 75, A gusset opening 28 is formed. When the take-out port 18 is opened, the portions other than the lid portion 78 (the cut-off gusset portion 30 and the protective gusset portion 40) try to spread away from the front and back sheets. At this time, force acts on the lid portion 78 in the unfolding direction, but the lid portion 78 is not unfolded because it is fixed to the front and back sheets. Therefore, the force acts on the lid portion 78 and each perforation line, whereby the downward gusset sheet 75 is cut along each perforation line (opening auxiliary portion) and slid to the gusset opening portion 28 and both sides in the width direction. A cut gusset portion 30 and a protective gusset portion 40 are formed.

  The pouch container 70 has the same feeling of use as the pouch container 10 after opening. In other words, according to the pouch container 70, good transportability of the downward gusset sheet 75 at the time of manufacture can be realized without impairing usability, and excellent productivity (mass productivity) is achieved.

The above embodiment can be appropriately changed in design without departing from the object of the present invention.
For example, in the above embodiments, a standing pouch has been exemplified, but the configuration of the present invention may be applied to other pouch configurations such as a flat pouch that does not have self-supporting properties.

  Further, a powder collection hole may be provided in the scraped gusset portion 30. The powder recovery hole has a function of returning the powder 100 placed on the upper surface 33 to the filling unit 14 by a scraping operation. The powder recovery hole can be provided by cutting a part of the part where the crease line 26 is formed, for example.
