It is joined.

  The bag body 2 has a pair of side end joint portions (also referred to as “center side end joint portions”) 10 and 10 that join the side end portion 4b of the first face sheet 4 and the side end portion 5b of the second face sheet 5. It has. The bag body 2 includes a first lower end joining portion 11 that joins the lower end portion 4 c of the first face sheet 4 and the first lower end portion 7 d of the second gusset sheet 7, and a lower end portion 5 c of the second face sheet 5.

Are joined, and the first and second lower side end joints 15 and 16 are joined together.

  In addition, if the bag body 2 (each sheet | seat 4-7) has flexibility and is formed with the material which can seal the content with which an inside is filled, it will not specifically limit. Usually, the sheets 4 to 7 are made of a resin film. The resin films constituting the sheets 4 to 7 are required to have basic performance as a packaging body such as impact resistance, wear resistance, and heat resistance.

  Moreover, since each said junction part 8-16 is normally formed by heat sealing, the heat sealing property is also requested | required of the sheets 4-7. As the sheets 4 to 7, a multilayer sheet having a base film layer and a sealant layer that imparts heat sealability is suitable, and when high gas barrier properties are required, the base film layer and the sealant layer It is preferable to provide a gas barrier layer therebetween.

  In addition, you may provide gas barrier property to the base film layer itself. In this case, a multilayer sheet having a barrier layer and a sealant layer is obtained using the barrier layer as a base film layer. In addition, when providing heat sealability on both sides of the sheet, a single-layer film that forms a sealant layer described later may be used, or in the case of a multilayer sheet, whether two layers of the same or different sealant layers are used. (At this time, one layer of the sealant layer is formally used as the base film layer), or a sheet having a sealant layer on both sides of the base film layer may be used.

  Here, constituent materials of the base film layer, the sealant layer, and the gas barrier layer are exemplified. These layers can be laminated by a conventional laminating method, for example, dry lamination using an adhesive, thermal lamination in which a heat-adhesive layer is sandwiched by heat and the like.

  Examples of the film constituting the base film layer include polyester (polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polybutylene terephthalate (PBT), polycarbonate (PC), etc.), polyolefin (polyethylene (PE), polypropylene ( PP)), polyamide (nylon-6, nylon-66, etc.), polyacrylonitrile (PAN), polyimide (PI), polyvinyl chloride (PVC), polyvinylidene chloride (PVDC), polymethyl methacrylate (PMMA), and A stretched or unstretched film of one layer or two or more layers composed of polyethersulfone (PES) or the like can be exemplified. The thickness of the base film is, for example, 10 μm to 200 μm, preferably 10 μm to 100 μm.

  The films constituting the sealant layer include low density polyethylene (LDPE), linear low density polyethylene (LLDPE), ethylene-propylene copolymer (EP), unstretched polypropylene (CPP), and biaxially stretched nylon (ON). , Ethylene-olefin copolymer, ethylene-acrylic acid copolymer (EAA), ethylene-methacrylic acid copolymer (EMAA), ethylene-vinyl acetate copolymer (EVA), etc. A stretched or unstretched film can be exemplified. The thickness of the sealant layer is, for example, 20 μm to 200 μm, preferably 30 μm to 180 μm.

  The gas barrier layer may be a metal thin film such as aluminum, a resin film such as vinylidene chloride (PVDC) or ethylene-vinyl alcohol copolymer (EVOH), or any synthetic resin film (for example, a base film layer). ), And a film obtained by vapor-depositing (or sputtering) an inorganic oxide such as aluminum, aluminum oxide or silica.

  Each sheet 4 to 7 can be provided with a printing layer for displaying the product name of the content, the raw material of the content, the product description such as precautions for use, and other various designs. For example, the printing layer can be formed on the inner surface of the base film layer by a known method such as gravure printing.

  In addition, since each joining part 8-16 will not be specifically limited if the sheets 4-7 overlap and are fixed, not only the sheets 4-7 are heat-welded but also the sheet 4 ˜7 may be formed by, for example, bonding with an adhesive or ultrasonic waves. Therefore, for example, the structure that the bag 2 (each sheet 4-7) is formed with the non-heat-weldable film may be sufficient.

  The extraction body 3 is formed in a cylindrical shape. And the pouring body 3 is comprised so that attachment or detachment to the cap 17 is possible. In addition, it is preferable that the extraction body 3 is being fixed to the center part 4d of the upper end part 4a of the 1st surface sheet 4. FIG. In addition, the center area | region is called the center part 4d among the area | regions which divided the upper end part 4a of the 1st surface sheet 4 into three equal parts, and an outer area | region is called side part 4e, 4e.

  Moreover, the extraction | pouring body 3 will not be specifically limited if it is formed with the material which has predetermined | prescribed rigidity. For example, when the bag body 2 (each sheet 4-7) is formed with the resin film which has heat welding property, the extraction | pouring body 3 may be formed with thermoadhesive resin, such as polyethylene and a polypropylene. ,preferable.

  By the way, the inner edges 13 a and 14 a of the first and second upper side end joint portions 13 and 14 intersect with the bent portion 6 a of the first gusset sheet 6 in an inclined manner. Thereby, as compared with the configuration in which the inner edges 13a, 14a are orthogonal to the bent portion 6a, the bag breaking resistance can be improved. Specifically, when the bag body 2 is filled with contents and the bag body 2 falls, it can be reduced that the internal pressure is concentrated on the intersection between the inner edges 13a, 14a and the bent portion 6a. Therefore, it can suppress that a bag breaks.

  Further, each of the first and second upper side end joint portions 13 and 14 includes non-joint portions 13b and 14b therein. The non-joining portions 13b and 14b are regions where the first gusset sheet 6 and the face sheets 4 and 5 are not joined, and thus are more flexible than the surroundings. Thereby, for example, when the contents are filled in the bag body 2 and the bag body 2 is dropped, the impact of the drop can be absorbed by the non-joining portions 13b and 14b. Therefore, the bag-proofing performance can be further improved.

  Moreover, in the 1st gusset sheet | seat 6, the dimension of the up-down direction D3 of the 1st sheet | seat part 6b is larger than the dimension of the up-down direction D3 of the 2nd sheet | seat part 6c. Accordingly, the dimension of the first face sheet 4 in the vertical direction D3 is larger than the dimension of the second face sheet 5 in the vertical direction D3. Thereby, the distance W1 from the bent portion 6a of the first gusset sheet 6 to the first upper end joined portion 8 is larger than the distance W2 from the bent portion 6a of the first gusset sheet 6 to the second upper end joined portion 9. It is getting bigger.

  On the other hand, in the second gusset sheet 7, the vertical dimension D3 of the first sheet part 7b is the same as the vertical dimension D3 of the second sheet part 7c. Thereby, the distance W3 from the bent portion 7a of the second gusset sheet 7 to the first lower end joint portion 11 is the same as the distance W4 from the bent portion 7a of the second gusset sheet 7 to the second lower end joint portion 12. It has become.

  Further, the inner edge 18 of the side end joint portion 10 includes a concave portion 18a that is recessed inward, and the outer edge 19 of the side end joint portion 10 similarly includes a concave portion 19a that is recessed inward. The recesses 18a and 19a are arranged in the center of the side end joint 10 respectively. Specifically, the recesses 18 a and 19 a are respectively disposed in the center of the bag body 2 in the vertical direction D3.

  Furthermore, the 1st surface sheet 4 is provided with the inclination means 4f which inclines the side edge junction part 10 to the 1st surface sheet 4 side. In the present embodiment, the tilting means 4 f is configured by a fold line extending along the inner edge 18 of the side end joint 10. Therefore, the inclination means 4f is formed so that the side end joint portion 10 is inclined toward the first face sheet 4 side. Specifically, the inclination means 4f is formed so that the side end joint portion 10 is easily bent toward the first face sheet 4 side.

  In addition, the inclination means 4f comprised by a fold line will not be specifically limited if the side edge junction part 10 is the structure which inclines to the 1st surface sheet 4 side. For example, the inclination means 4 f configured by a folding line may be configured such that a continuous or intermittent groove is formed on the outer surface side of the first face sheet 4. Moreover, the position and the number of the inclination means 4f comprised by a folding line are not specifically limited.

  Moreover, the 1st surface sheet 4 is provided with the display part 4g. The display unit 4g displays information that prompts the user to hold the bag 2 with the first face sheet 4 facing upward. In addition, the position of the display part 4g may be the 2nd surface sheet 5, for example, and is not specifically limited.

  Next, the pouch packaging body 20 in which the contents of the pouch container 1 according to the present embodiment are filled will be described with reference to FIGS. Hereinafter, unless otherwise specified, as shown in FIGS. 4 to 8, the pouch container 1 in a state where contents are filled therein will be described.

  As shown in FIGS. 4 to 6, the pouch packaging body 20 includes a pouch container 1 in which contents are filled in the bag body 2, and a cap 17 that is attached to and detached from the pouring body 3 of the pouch container 1. ing. And the bag body 2 is formed in the cylinder shape by the 1st surface sheet 4 and the 2nd surface sheet 5 in the state with which the content was filled inside, and it is formed so that it can become independent.

  And since the recessed part 18a is formed in the side edge junction part 10, when the pouch container 1 becomes independent as shown in FIG.4 and FIG.5, the bag body 2 deform | transforms from the recessed part 18a as a starting point. Specifically, the constriction 20a is formed in the bag body 2 due to its own weight.

  Further, the distance W1 from the bent portion 6a of the first gusset sheet 6 to the first upper end joined portion 8 is larger than the distance W2 from the bent portion 6a to the second upper end joined portion 9, and The distance W3 from the bent portion 7a of the second gusset sheet 7 to the first lower end joined portion 11 is the same as the distance W4 from the bent portion 7a to the second lower end joined portion 12. As a result, as shown in FIG. 6, the curved shape (deformed state) of the first face sheet 4 is gentler than the curved shape (deformed state) of the second face sheet 5 in the vertical direction D3.

  Therefore, as shown in FIGS. 4 and 5, the region of the first face sheet 4 where the constriction 20a is formed in the lateral direction D2 is reduced. Specifically, the width W5 of the planar region (region in which the constriction 20a is not formed) in the lateral direction D2 of the first face sheet 4 is larger than the width W6 of the planar region in the lateral direction D2 of the second face sheet 5. Is also getting bigger. Therefore, for example, the design of the first face sheet 4 can be improved. For example, the information displayed on the first face sheet 4 can be accurately transmitted.

  Further, since the curvature of the first face sheet 4 is gentler than that of the second face sheet 5, the side end joint portion 10 is easily inclined toward the first face sheet 4. And since the 1st surface sheet 4 is provided with the inclination means 4f, the side edge junction part 10 inclines to the 1st surface sheet 4 side reliably. Specifically, the side end joint portion 10 is bent toward the first face sheet 4 side starting from the inclined means 4f.

  And as shown in FIG. 7, with respect to the above pouch packaging body 20, as shown in FIG. 7, the pouch container 1 can be easily held with one hand. And since the recessed part 19a (not shown in FIG. 7) is formed in the outer edge 19 of the side end junction part 10, the constriction 20a can be grasped easily.

  By the way, when the first face sheet 4 is held downward, the contents are accumulated at the lower position, that is, the position of the pouring body 3, and the contents are poured out at a stroke, and the amount of the contents poured out. Difficult to adjust. On the other hand, as shown in FIGS. 7 and 8, when the first face sheet 4 is held upward, the contents flow up to the position of the pouring body 3 by tilting the pouch container 1, The amount of contents dispensed can be adjusted.

  At this time, as shown in FIG. 8, since the side end joint portion 10 is bent toward the first face sheet 4, the finger can be prevented from coming into contact with the outer edge 19 of the side end joint portion 10. Thereby, irritation | stimulation (for example, pain) which a finger | toe receives from the side edge junction part 10 can be made small.

  The pouch container 1 may have a configuration in which a non-slip portion is provided at a position where the finger of the second face sheet 5 contacts in order to prevent the finger from slipping from the second face sheet 5. For example, the non-slip portion may be formed by being embossed on the surface of the second face sheet 5, and may be formed by applying a non-slip varnish to the surface of the second face sheet 5. It may be configured. Further, for example, the anti-slip portion may be formed of an anti-slip seal attached to the surface of the second face sheet 5.

  Next, details of the side end joint portion 10 according to the present embodiment will be described with reference to FIG. In addition, the side end joint part 10 which concerns on this embodiment, and the side end joint part 10 of the modification concerning FIG. 10 are compared and demonstrated.

  As shown in FIG. 9, a concave portion (hereinafter also referred to as “outer edge concave portion”) 19a of the outer edge 19 includes a bottom portion 19b formed in a curved shape and a curved portion 19c connected to the bottom portion 19b. The bottom portion 19b is curved to be convex inward in the horizontal direction D2, and the curved portion 19c is curved to be convex outward in the horizontal direction D2.

  In the side end joint portion 10 according to the present embodiment, the concave portion (hereinafter, also referred to as “inner edge concave portion”) 18a of the inner edge 18 is curved inwardly toward the bottom portion 18b and the bottom portion 18b. A straight portion 18c that is inclined with respect to the vertical direction D3 is provided. Thereby, the width W7 of the side end joint part 10 in the straight part 18c is larger than the width W8 of the side end joint part 10 in other parts.

  On the other hand, as shown in FIG. 10, in the side end joint portion 10 of the modification, the concave portion 19a of the outer edge 19 has the same shape as the side end joint portion 10 according to the present embodiment. And the recessed part 18a of the inner edge 18 is equipped with the curved bottom part 18b and the curved part 18d connected with the bottom part 18b so that the width | variety W8 of the side end junction part 10 may become fixed.

  Therefore, in the side end joint portion 10 according to the modification, a dead space (a space surrounded by a two-dot chain line and a broken line in FIG. 10) S1 is formed by the curved portion 18d. In the side end joint portion 10, the dead space S <b> 1 is not formed. Thereby, according to the side end junction part 10 which concerns on this embodiment, the inside of the bag body 2 can be utilized effectively. The dead space S <b> 1 is a space that is formed when the first face sheet 4 and the second face sheet 5 are hardly separated and cannot be filled with the contents.

  Further, although the outer edge 19 has the same shape, the width W8 of the side end joint portion 10 according to the modification is constant, whereas in the side end joint portion 10 according to the present embodiment, in the straight portion 18c, The width W7 of the side end joint portion 10 is increased. Thereby, according to the side end joint part 10 which concerns on this embodiment, since the rigidity of the side end joint part 10 can be enlarged, the side end joint part 10 becomes easy to catch on a finger | toe. Therefore, the pouch container 1 can be more easily held with one hand.

  In the pouch container 1 according to the above-described embodiment, the recess 18a includes a linear portion 18c that is inclined with respect to the vertical direction D3 so as to go inward toward the bottom 18b. However, the pouch container 1 is not limited to such a configuration although such a configuration is preferable. For example, like the pouch container 1 according to the modification, the side end joint portion 10 may be formed so that the width W8 is constant.

  As described above, the pouch container 1 according to the present embodiment includes the bag body 2 and the pouring body 3 that allows the inside and the outside of the bag body 2 to communicate with each other, and the bag body 2 includes the first face sheet 4. And a second face sheet 5 facing the first face sheet 4, and a gusset sheet 6 arranged between the first face sheet 4 and the second face sheet 5, the pouring body 3 is disposed between the first face sheet 4 and the gusset sheet 6 and joined to the upper end portion 4a of the first face sheet 4 and the first upper end portion 6d of the gusset sheet 6, respectively. The body 2 includes a pair of side end joints 10, 10 that join the side end 4 b of the first face sheet 4 and the side end 5 b of the second face sheet 5. The inner edge 18 includes a recess 18a that is recessed inward.

  According to such a configuration, since the inner edge 18 of the side end joint portion 10 is provided with the concave portion 18a that is recessed inward, when the contents are filled in the pouch container 1, the bag body 2 includes , A constriction 20a is formed. Thereby, it becomes easy to hold the pouch container 1 by grasping the constriction 20a.

  Moreover, in the pouch container 1 which concerns on this embodiment, the said bag body is provided with the 2nd gusset sheet | seat arrange | positioned between the said 1st surface sheet | seat and the said 2nd surface sheet | seat, and below the said gusset sheet | seat. The bag body 2 includes a first upper end joining portion 8 that joins the upper end portion 4 a of the first face sheet 4 and the first upper end portion 6 d of the gusset sheet 6, and an upper end of the second face sheet 5.

A first lower end joining portion, a second lower end joining portion joining the lower end portion of the second face sheet and the second lower end portion of the second gusset sheet, and from the bent portion 6a of the gusset sheet 6 The distance W1 to the first upper end joint 8 is The distance from the bent portion 6a of the zet sheet 6 to the second upper end joint portion 9 is larger than the distance W2, and the distance from the bent portion of the second gusset sheet to the first lower end joint portion is the second It is the structure that it is the same as the distance from the said bending part of a gusset sheet | seat to the said 2nd lower end junction part.

  According to such a configuration, when the contents of the pouch container 1 are filled and the pouch container 1 is self-supporting, the curved shape (deformed state) of the first face sheet 4 in the vertical direction D3 is the second. The bag body 2 is deformed so as to be gentler than the curved shape (deformed state) of the face sheet 5. Thereby, the area | region where the constriction 20a in the horizontal direction D2 of the 1st surface sheet 4 is formed becomes small.

  Moreover, in the pouch container 1 according to the present embodiment, the concave portion 18a includes a linear portion 18c that is inclined with respect to the vertical direction D3 so as to go inward toward the bottom portion 18b.

  According to such a configuration, since the concave portion 18a includes the linear portion 18c, it is possible to suppress the dead space S1 from being generated in the bag body 2. Moreover, since the width W7 of the side end joint portion 10 can also be increased, the rigidity of the side end joint portion 10 can be increased.

  Further, the pouch container 1 according to the present embodiment is configured to include an inclination means 4f for inclining the side end joint portion 10 toward the first face sheet 4 side.

  According to such a configuration, the side end joint portion 10 is inclined toward the first face sheet 4 by the inclination means 4f. Then, when the pouch container 1 is held with one hand so that the palm is in contact with the first face sheet 4, the side end joint 10 is inclined toward the first face sheet 4, whereby the side end joint 10. The stimulus received on the finger from the outer edge 19 can be reduced.

  Note that the pouch container 1 is not limited to the configuration of the above-described embodiment, and is not limited to the above-described effects. Of course, the pouch container 1 can be variously modified without departing from the gist of the present invention. For example, it is needless to say that one or a plurality of configurations and methods according to various modifications described below may be arbitrarily selected and employed in the configurations and methods according to the above-described embodiments.

(1) In the pouch container 1 according to the above embodiment, the inner edges 13a, 14a of the first and second upper side end joint portions 13, 14 are inclined with respect to the bent portion 6a of the first gusset sheet 6. Crossing each other. However, the pouch container 1 is not limited to such a configuration. For example, as shown in FIG. 11, the inner edge 14a of the second upper side end joint portion 14 (not shown in FIG. 11, but also the inner edge 13a of the first upper side end joint portion 13) is the first gusset sheet. It may be configured to be orthogonal to the six bent portions 6a.

(2) Moreover, in the pouch container 1 which concerns on the said embodiment, it is the structure that the non-joining part 13b is arrange | positioned at the 1st upper side edge junction part 13. FIG. However, the pouch container 1 is not limited to such a configuration. For example, as illustrated in FIG. 12, the non-joining portion 13 b may be disposed across the first upper side end joining portion 13 and the first upper end joining portion 8.

(3) Moreover, in the pouch container 1 which concerns on the said embodiment, it is the structure that the outer edge 19 of the side end junction part 10 is equipped with the recessed part 19a. However, the pouch container 1 is not limited to such a configuration. For example, the configuration in which the outer edge 19 of the side end joint portion 10 is not provided with the concave portion 19a and is formed linearly over the entire length in the vertical direction D3.

(4) Moreover, in the pouch container 1 which concerns on the said embodiment, the distance W1 from the bending part 6a of the 1st gusset sheet 6 to the 1st upper end junction part 8 is the said 2nd upper end junction part from the said bending part 6a. It is the structure that it is larger than the distance W2 to 9. However, the pouch container 1 is not limited to such a configuration although such a configuration is preferable. For example, the distance W1 from the bent portion 6a of the first gusset sheet 6 to the first upper end joined portion 8 is the same as the distance W2 from the bent portion 6a to the second upper end joined portion 9. Good.

(5) Moreover, in the pouch container 1 which concerns on the said embodiment, it is the structure that the inclination means 4f is a folding line extended along the inner edge 18 of the side end junction part 10. FIG. However, the pouch container 1 is not limited to such a configuration. For example, the inclination means has the side face joint portion 10 on the first face sheet 4 side at least in the vicinity of the side face joint portion 10 because the rigidity of the second face sheet 5 is larger than the rigidity of the first face sheet 4. It may be configured to be inclined. Two examples of such tilting means are described below.

(5-1)
As a first example, as shown in FIG. 13, the tilting means 21 may be a reinforcing material attached to the second face sheet 5. A part of the tilting means 21 is disposed at the side end joint portion 10, and a part of the tilting means is disposed inside the lateral direction D <b> 2 relative to the side end joint portion 10.

  According to such a configuration, as shown in FIG. 14, when the contents of the pouch container 1 are filled, the second face sheet 5 is deformed into a curved shape that protrudes backward. On the other hand, since the inclination means 21 tries to maintain a flat shape, the side edge joining part 10 inclines to the 1st surface sheet 4 side.

  In addition, the inclination means 21 comprised with a reinforcing material should just be provided with at least 1 with respect to the one side edge junction part 10, and a position and a number are not specifically limited. Moreover, the inclination means 21 comprised with a reinforcement material will not specifically limit the material etc., if there exists an effect mentioned above by partially reinforcing the 2nd surface sheet 5. As shown in FIG.

  A specific configuration of the tilting means 21 includes, for example, a configuration including a sheet-like base material made of resin or the like and an adhesive layer laminated on the base material. Alternatively, the tilting means 21 may have a configuration obtained by applying a liquid material or the like and curing it.

(5-2)
Further, as a second example, a configuration in which the second face sheet 5 also serves as a tilting means when the rigidity of the second face sheet 5 is larger than the rigidity of the first face sheet 4 may be adopted. According to such a configuration, since the rigidity of the second face sheet 5 is larger than the rigidity of the first face sheet 4 when the contents of the pouch container 1 are filled, in the vicinity of the side end joint portion 10. Is more flat on the second face sheet 5 side than on the first face sheet 4 side. Thereby, the side edge junction part 10 inclines to the 1st surface sheet 4 side.

  The structure of the 2nd surface sheet 5 which serves as an inclination means will not be specifically limited if the rigidity of the 2nd surface sheet 5 is larger than the rigidity of the 1st surface sheet 4. FIG. For example, the first side sheet 4 has a configuration in which each of the base film layer, the sealant layer, and the gas barrier layer is a single layer, whereas the second side sheet 5 has a configuration of the base film layer, the sealant layer, and the gas barrier layer. The structure that at least one is a multilayer may be used. In other words, the second surface sheet 5 may be thicker than the first surface sheet 4.

  Further, for example, in the first face sheet 4 and the second face sheet 5, the base film layer, the sealant layer, and the gas barrier layer have the same number of layers, respectively, while the rigidity of the second face sheet 5 in the predetermined layer is the first. The structure of being larger than the rigidity of the single sheet | seat 4 may be sufficient. That is, although the thickness of the 1st surface sheet 4 and the thickness of the 2nd surface sheet 5 are the same, the structure that the rigidity of the 2nd surface sheet 5 is larger than the rigidity of the 1st surface sheet 4 may be sufficient.

(6) Further, the pouch container 1 according to the above embodiment is configured to include the tilting means 4f. However, the pouch container 1 is not limited to such a configuration although such a configuration is preferable. For example, the pouch container 1 may be configured not to include the tilting means 4f.
