It is a schematic front view which showed an example of the body 50. In the following, for convenience of description, in the state of FIG. 1 in which the packaging container 1 is placed, the side of the opening 14 of the outer bag 10 to be described below is set to be the upper side, and the side of the bottom surface portion 17 is set to be the lower side of the drawing. Is the front and the back of the figure is the back. A line III-III in FIG. 1 is a straight line that vertically cuts an inner bag 11 described later, and FIG. 3 is a vertical schematic cross-sectional view of the packaging container 1.

  As shown in FIGS. 1 to 3, the packaging container 1 according to the present embodiment includes an outer bag 10 having an opening 14 at an upper end, an inner bag 11 having liquid permeability, and an opening 14 of the outer bag 10. The re-sealing member 12 for sealing the opening 24 of the inner bag 11 with the part left. In the packaging container 1, the resealing member 12 leaves a part of the opening 14 of the outer bag 10 so that the side where the inner bag 11 is located and the opening 14 of the outer bag 10 communicate with each other inside the outer bag 10. The flow path portion 13 is configured to be formed. In addition, below, the case where the content accommodated in the packaging container 1 is an extraction target for extracting a beverage, a seasoning, or the like will be described as an example.

  The outer bag 10 is composed of a flexible film which is a laminate in which at least a sealant layer and a base material layer are sequentially laminated. The outer bag 10 is formed in a bag shape by laminating films so that the sealant layer is on the inner surface and bonding the outer peripheral edge portions. The sealant layer may have a property that it does not affect the physical properties of the contents and is melted by heat and fused to each other. As the sealant layer, for example, a linear low density polyethylene (LLDPE) film or sheet is used. The thickness of the sealant layer is preferably 15 μm to 300 μm, more preferably 20 μm to 60 μm.

  As the material of the sealant layer, in addition to linear low-density polyethylene, for example, low-density polyethylene, medium-density polyethylene, high-density polyethylene, polypropylene, ionomer, ethylene-vinyl acetate copolymer, ethylene-acrylic acid copolymer, Ethylene-ethyl acrylate copolymer, ethylene-methacrylic acid copolymer, ethylene-propylene copolymer, methylpentene polymer, polybutene polymer, acid-modified polyolefin resin, polymer alloy of polypropylene and polystyrene, polypropylene and polyethylene Blend resins are mentioned, and these resins can be used alone or in a mixture of two or more resins.

  The base material layer may be a material having strength as a base material of a packaging bag. As the base material layer, for example, a synthetic resin film is used, and in particular, a biaxially stretched thermoplastic resin film is used. As the base material layer, for example, a biaxially-oriented polyethylene terephthalate (BOPET) film is used. The thickness of the base material layer is preferably 6 μm to 30 μm, and more preferably 9 μm to 15 μm. If the base material layer is too thin, the strength tends to be insufficient, and if it is too thick, the cost increases.

  As the material of the base material layer, polyester resin, polyamide resin, polyethylene resin, polypropylene resin, polycarbonate resin, polyacetal resin, fluorine resin, and other various resins can be used.

  The film that is a laminated body may be provided with a printing layer on the front surface or the back surface of the base material layer, for example. In addition, depending on the contents to be contained, a gas barrier property that blocks the permeation of oxygen and water vapor, a light blocking property that blocks visible light and ultraviolet rays, a puncture resistance, and a resistance between the sealant layer and the base material layer. An intermediate layer for adding flexibility, heat resistance, etc. may be further provided, and the intermediate layer may have a multi-layer structure. Examples of the layer that imparts gas barrier properties include vapor-deposited films of aluminum oxide and silicon oxide, and examples of layers that impart puncture resistance include polyamide resin films. Further, an outer layer may be provided on the surface of the base material layer. The outer layer plays a role of protecting the packaging bag, and a synthetic resin film, for example, can be used as in the above-mentioned base material layer.

  The method for laminating each layer is not limited, and the layers can be laminated by dry lamination using a polyurethane adhesive, for example. In addition, from the viewpoint of convenience, it is preferable that the film forming the outer bag 10 has such transparency that the contents can be visually observed and can be heated by a microwave oven. The layer structure of such a film is, for example, linear low-density polyethylene (60 μm: sealant layer)/aluminum oxide vapor deposition film (20 nm: intermediate layer)/polyethylene terephthalate (12 μm: base material layer). You can

  The outer bag 10 is formed from a film as a laminate having the above-described layer structure. The outer bag 10 is formed into a bag shape by folding and stacking the films so that the sealant layer is on the inner surface side and adhering the outer peripheral edge portions. The film may be adhered at the time of bag making by a method using an adhesive. However, since a linear low-density polyethylene film, for example, is used as the sealant layer in the film that is a laminated body, the method by heat sealing (heat fusion) can be easily produced, which is preferable.

  The outer bag 10 includes an opening 14 at an upper end, a front surface portion 15, a back surface portion 16, and a bottom surface portion 17, and is a rectangular bottom bag having a flat bottom surface portion 17 and a rectangular shape in bottom view. The bottom surface portion 17 is configured to be self-supporting with the placement surface. Although details will be described later, the outer bag 10 is formed by folding a lower portion of a rectangular packaging bag having an opening 14 at an upper end in a front view. The surface portion 15 is formed on one side of the folded and superposed films and is located on the front side of FIG. 1. The back surface portion 16 is formed on the other side of the folded and superposed films and is located on the back side in FIG. 1. The outer bag 10 is configured to hermetically accommodate the contents by sealing the opening 14.

  The outer bag 10 is a square bottom bag formed by folding the lower part of a so-called pouch, and includes a lower seal 18, a backing sticker 19, a grip 20, and a grip 20 to which laminated films are adhered. It also has a notch 21 and a through hole 22, which are provided, and a planned opening 23.

  The lower seal 18, the backing sticker 19, and the gripping portion 20 are formed by heat-sealing a film in which the sealant layer is on the inner surface side, and the films that are folded so that the sealant layers face each other are heat-sealed. Have. The lower seal 18 is located on the bottom surface portion 17 and corresponds to the bottom of the pouch. The backing sticker 19 is located on the back surface portion 16 and extends in the vertical direction. The grip portion 20 is located on the outer peripheral edge portion of the outer bag 10, that is, on the upper right side in FIG. 1, and is formed in a substantially triangular shape having the upper end and the right end of the outer bag 10 as two sides. The lower seal 18, the back-sticking seal 19, and the grip 20 have adhesive strength capable of holding the extraction liquid inside during the extraction described later.

  The grip portion 20 has a notch 21 as an opening means that triggers tearing of the film forming the outer bag 10. The notch 21 is a V-shaped notch that extends inward from the outer end of the grip portion 20, has a predetermined distance from the upper end of the outer bag 10, and is located above the reseal member 12 (on the side of the opening 14 ). ) Is located. Further, the grip portion 20 has a circular through hole 22 penetrating from the front surface side to the back surface side.

  The grip 20 has a shape in which the width gradually increases from the lower side to the upper side, but the shape, arrangement, and number are not limited, and can be appropriately set according to the form of the outer bag 10. Further, the notch 21 may have any structure as long as it triggers tearing of the film, and may be, for example, a U-shaped notch or an I-shaped notch. Further, the shape and size of the through hole 22 are not particularly limited, and may be, for example, a polygonal shape or an elliptical shape. In addition, the notch 21 and the through hole 22 may be formed in a portion where a laminated film different from the grip portion 20 is heat-sealed.

  The unsealed portion 23 has a predetermined distance from the upper end (opening 14) of the outer bag 10 and extends in the left-right direction from the notch 21 along the upper end. The unsealed portion 23 is a weakening line in which the strength of the film forming the outer bag 10 is weakened, and is formed on the front surface portion 15 and the back surface portion 16. The to-be-opened portion 23 has a function of guiding a tear that propagates when the film forming the outer bag 10 is torn from the notch 21 as a starting point onto the to-be-opened portion 23. Examples of the line of weakness include a half cut in which a cut is made from the inner surface side or the outer surface side of the film to the middle in the thickness direction. The through hole 22 is preferably provided at a position where it does not intersect with the unsealed portion 23, and does not prevent tearing of the film starting from the notch 21.

  The liquid-permeable inner bag 11 is made of a liquid-permeable and flexible sheet member, and is formed in a bag shape having an opening 24 at the upper end. The inner bag 11 is attached inside the outer bag 10 so that the opening 24 at the upper end communicates with the opening 14 of the outer bag 10. The sheet member that constitutes the inner bag 11 is a material that has flexibility and does not affect the physical properties of the contents, such as pulp, cotton, hemp, silk, or a synthetic resin, or a single material. It is possible to use a woven fabric or a non-woven fabric configured by mixing two or more. The inner bag 11 may have a liquid-permeable property and does not allow the contents (solid matter) contained therein to permeate, and may be composed of, for example, a synthetic resin film having many fine through holes. Well, its configuration, material, thickness, water permeability, etc. are appropriately set according to the contents. From the viewpoint of convenience, it is preferable that the inner bag 11 has a structure capable of being heated in a microwave oven, like the film forming the outer bag 10.

  The inner bag 11 is a so-called palm bag composed of a sheet member having liquid permeability and flexibility, and has a front surface portion 25, a back surface portion 26, a lower seal 27, and a back sticking seal 28. The opening 24, which is the upper end of the inner bag 11, has a predetermined distance from the upper end (opening 14) of the outer bag 10, and is located below the unsealed portion 23. The upper end of the inner bag 11 is substantially parallel to the upper end of the outer bag 10 and the scheduled opening portion 23. The lower end (lower seal 27) of the inner bag 11 has a predetermined distance from the bottom surface portion 17 of the outer bag 10. The vicinity of the upper end of the surface portion 25 of the inner bag 11 is partially bonded to the inner surface of the surface portion 15 of the outer bag 10 (see FIG. 3 ). On the other hand, the vicinity of the upper end of the back surface portion 26 of the inner bag 11 is partially bonded to the inner surface of the back surface portion 16 of the outer bag 10. The opening 24 at the upper end of the inner bag 11 communicates with the opening 14 of the outer bag 10.

  The inner bag 11 may be adhered to the outer bag 10 by using an adhesive. However, since a linear low-density polyethylene film, for example, is used as the sealant layer in the film that is the laminated body that constitutes the outer bag 10, it is preferable because the method by heat fusion can be easily manufactured. Therefore, the inner bag 11 is preferably configured to be heat-sealed to the film forming the outer bag 10, for example, low density polyethylene, medium density polyethylene, high density polyethylene, linear low density polyethylene, Examples include polyolefin resins such as polypropylene, and non-woven fabrics made of a mixture of these resins. Further, at least the vicinity of the upper end of the inner bag 11 may be partially adhered to the outer bag 10, and the part other than the vicinity of the upper end may be adhered to the outer bag 10.

  The form of the inner bag 11 is not limited to the joint bag, but may be any form having an opening 24 communicating with the opening 14 of the outer bag 10, such as a two-sided seal bag, a three-sided seal bag, and a gusset. It can be used by selecting from various packaging forms such as bags.

  The resealing member 12 is a so-called zipper, which is composed of a male member 12 a and a female member 12 b that are fluid-tightly fitted to each other, and is attached inside the outer bag 10. The resealing member 12 extends along the upper end (opening 24) of the inner bag 11, and one end, the right end in FIG. 1, is joined to the grip portion 20. The end of the resealing member 12 in the grip portion 20 is sandwiched between the superposed films, and the end of the resealing member 12 is adhered to the grip portion 20 in a state of being sandwiched. The other end of the resealing member 12, that is, the left end in FIG. 1, has a predetermined distance from the outer peripheral edge portion on the left side of the outer bag 10.

  The male member 12a of the resealing member 12 is bonded to the inner surface of the surface portion 15 of the outer bag 10 with the convex fitting portion (not shown) facing inward. The female member 12b of the reseal member 12 is adhered to the inner surface of the back surface portion 16 of the outer bag 10 with the concave fitting portion (not shown) that fits liquid-tightly with the convex fitting portion faces inward. .. Then, the resealing member 12 liquid-tightly joins the inner surface of the outer bag 10 to the inner surface of the outer bag 10 by fitting the male member 12a and the female member 12b to each other. The opening 24 of the bag 11 can be sealed, and the male member 12a and the female member 12b are disengaged from each other, thereby separating the inner surface of the front surface portion 15 of the outer bag 10 from the inner surface of the back surface portion 16 of the outer bag 10. It is configured so that the opening 24 of 11 can be opened.

  Here, since the left end of the resealing member 12 has a predetermined distance from the outer peripheral edge portion on the left side of the outer bag 10, the male member 12a and the female member 12b are fitted to each other to open the opening 24 of the inner bag 11. When the bag is sealed, the opening 14 of the outer bag 10 is not completely sealed and a part is left. Then, the resealing member 12 leaves a part of the opening 14 of the outer bag 10, so that the flow path portion 13 for communicating the side where the inner bag 11 is located and the opening 14 of the outer bag 10 inside the outer bag 10. It is formed.

  Here, the resealing member 12 may be configured so as to seal the opening 24 of the inner bag 11 while leaving a part of the opening 14 of the outer bag 10 and can be resealed. The above-mentioned resealing member 12 has a configuration in which the right end is joined to the grip 20 and the fitting between the male member 12a and the female member 12b is not disengaged, but the right end is not joined to the grip 20. Is also good. With such a configuration, the opening 14 of the outer bag 10 and the opening 24 of the inner bag 11 can be further widened, which is convenient. Further, the left end of the resealing member 12 is configured such that the male member 12a and the female member 12b are disengaged from each other, but the inner surface and the back surface portion of the front surface portion 15 of the outer bag 10 around the left end of the resealing member 12 are removed. The inner surface of 16 is heat-sealed, and the left end of the resealing member 12 is sandwiched between the front surface portion 15 and the back surface portion 16 of the outer bag 10, and the male member 12a and the female member 12b are fitted at the left end. It may be a configuration that does not come off. With such a configuration, the tightness of the opening 24 of the inner bag 11 is improved.

  The material of the resealing member 12 is a material that has flexibility and does not affect the physical properties of the contents, for example, polyester resin, polyamide resin, polyethylene resin, polypropylene resin, polycarbonate resin, polyacetal. Resins, fluorine resins, and other various resins can be used. The resealing member 12 may be adhered to the outer bag 10 by using an adhesive. However, since a linear low-density polyethylene film, for example, is used as the sealant layer in the film that is the laminated body that constitutes the outer bag 10, it is preferable because the method by heat fusion can be easily manufactured. Therefore, the resealing member 12 is preferably made of a material that can be heat-sealed to the film forming the outer bag 10, and includes, for example, low density polyethylene, medium density polyethylene, high density polyethylene, and linear low density. Examples thereof include polyolefin resins such as polyethylene and polypropylene, and resins composed of a mixture thereof. From the viewpoint of convenience, it is preferable that the resealing member 12 be configured to be compatible with heating in a microwave oven, like the film forming the outer bag 10.

  The resealing member 12 is not limited to the above-described configuration in which the male member 12a and the female member 12b are fitted together, and the inner surface of the front surface portion 15 and the inner surface of the rear surface portion 16 of the outer bag 10 are liquid. Any structure may be used as long as they can be closely joined and separated from each other and that the opening 24 of the inner bag 11 can be sealed and opened. For example, an adhesive capable of peeling and re-adhering may be applied in a strip shape on the inner surface of the front surface portion 15 and the inner surface of the back surface portion 16.

  After the contents are accommodated in the inner bag 11 of the packaging container 1 configured as described above through the opening 14, the opening 14 is sealed by the upper seal 29 as a sealing portion, and the packaging container 1 is sealed. The filling body 50 according to the embodiment is produced (see FIG. 4 ). That is, the filling body 50 includes the packaging container 1 further including the upper seal 29 that seals the opening 14 of the outer bag 10, and the contents accommodated in the inner bag 11.

  The upper seal 29 is formed by heat-sealing films, which are superposed so that the sealant layers face each other, like the lower seal 18, the back-sticking seal 19, and the grip 20 described above. That is, the inner surface of the front surface portion 15 and the inner surface of the back surface portion 16 of the outer bag 10 are heat-sealed. The upper seal 29 has a predetermined width and extends in the left-right direction along the upper end (opening 14) of the outer bag 10. The upper seal 29 is located above the planned opening portion 23 and does not include the planned opening portion 23. The upper seal 29 can keep airtightness and prevent quality deterioration due to oxidation of the contents. The through hole 22 described above may be formed in the upper seal 29.

  The substance to be extracted as the contents to be contained in the packaging container 1 may be one that extracts a beverage, a seasoning or the like, for example, a beverage material such as tea leaves or ground coffee beans used for extracting the beverage, It can be used as a soup stock material such as dried bonito, dried sardines, kelp, and dried shiitake mushrooms used for extracting soup stock. In addition, in the filling body 50 shown in FIGS. 4 and 5, the roasted and ground coffee beans 3 which is a beverage material is contained as the content.

  The packaging container 1 having such a configuration is opened by tearing the film forming the outer bag 10 with the notch 21 as a starting point and separating the upper portion of the outer bag 10. Here, since the outer bag 10 has the notch 21 and the scheduled opening portion 23, the packaging container 1 can be easily opened. Further, since the tear that propagates when being torn is guided to the unsealed portion 23, it does not propagate to the joint portion of the resealing member 12 with the film, so that unsealing failure can be prevented. From the viewpoint of openability, the outer bag 10 preferably has the notch 21 and the planned opening portion 23, but the outer bag 10 of the packaging container 1 may not have the notch 21 or the planned opening portion 23. A configuration may be adopted in which the front surface portion 15 and the back surface portion 16 of the bag 10 are separated from each other and the upper seal 29 as a sealing portion is peeled off to open the bag.

  Moreover, since the outer bag 10 and the inner bag 11 of the packaging container 1 have flexibility, the packaging container 1 may be placed at a portion indicated by the double-dashed fold line 30 in FIG. It can be folded and folded so that the bottom portion 17 faces the front as shown in FIG. Therefore, the volume of the filling body 50 can be reduced and the portability is excellent. Further, as compared with the case where the extraction liquid is stored in the container, the volume and weight are reduced, so that the transport efficiency is good. Further, since the packaging container 1 has the through hole 22, it can be hung and displayed even when it is in a state where it cannot be self-sustaining due to its small volume as shown in FIG. 5, and the display efficiency can be improved. .. Then, as will be described in detail later, the packaging container 1 can be used as an extraction container when the components are extracted from the stored contents after being opened. Furthermore, since the packaging container 1 after being used as the extraction container can be disposable, it is hygienic and excellent in convenience. Further, the packaging container 1 can be discarded in a folded state as in the state before opening shown in FIG. 5, and the volume of dust can be reduced.

  Next, a method for manufacturing the packaging container 1 according to this embodiment will be described in detail. FIG. 6 is a schematic view schematically showing an example of the manufacturing process of the packaging container 1. First, as shown in FIG. 6A, one film forming the outer bag 10 is prepared, and the film is bent and overlapped at two places so that the sealant layer faces the inner surface and faces each other. Then, the ends of the superposed films, that is, the center on the back side in the figure, are heat-sealed under the conditions of a predetermined temperature, pressure, and heating/pressurizing time, and are formed into a tubular shape having openings at the upper end and the lower end. . Here, the heat-sealed portion becomes the back-sticking seal 19, the film located in the front becomes the film forming the front surface portion 15, and the film located at the back side becomes the film forming the back surface portion 16, The opening becomes the opening 14. In addition, the prepared film is preliminarily provided with a half cut (not shown here) extending in parallel along the upper end at a position having a predetermined distance from the upper end, and the half cut is a portion 23 to be opened.

  Next, as shown in FIG. 6B, an inner bag 11 of a palm bag having an opening 24 at the upper end and a resealing member 12 including a male member 12a and a female member 12b are prepared and formed into a tubular shape. Mounted inside the film. The backing sticker 19 is located at the center of the back side in the left-right direction and extends in the up-down direction. The inner bag 11 has a predetermined distance from the opening at the upper end of the tubular film, and is arranged so that the opening at the upper end of the tubular film and the opening 24 of the inner bag 11 are parallel to each other. The front surface portion 25 and the back surface portion 26 near the upper end of the inner bag 11 are attached to the inner surface of the film forming the front surface portion 15 of the outer bag 10 and the inner surface of the film forming the back surface portion 16, respectively, at a predetermined temperature, pressure and heating. It is partially heat-sealed under the condition of pressing time. The resealing member 12 is arranged so as to extend in the left-right direction along the opening 24 of the inner bag 11, and the male member 12a and the female member 12b of the resealing member 12 respectively form the surface portion 15 of the outer bag 10. The inner surface and the inner surface of the film forming the back surface portion 16 are heat-sealed under the conditions of predetermined temperature, pressure, and heating/pressurizing time. Both ends of the resealing member 12 have a predetermined distance from the folds, which are the left and right outer peripheral edge portions of the tubular film. The order of attaching the inner bag 11 and the resealing member 12 to the tubular film is not particularly limited. For example, after the resealing member 12 is heat-sealed to the inside of the tubular film, the inner bag 11 is removed. It may be heat-sealed to the inside of the tubular film.

  Next, as shown in FIG. 6C, the upper right side of the tubular film is heat-sealed under the conditions of predetermined temperature, pressure, and heating/pressurizing time. Here, the heat-sealed portion has a triangular shape including a part of the upper end that is the outer peripheral edge of the tubular film, a part of the right fold, and the right end of the resealing member 12, and the grip portion 20. Becomes Then, a V-shaped notch extending leftward from the outer end, that is, the right end in the drawing, and a hole penetrating from the front side to the back side are formed in the grip portion 20. The notch and the hole thus formed serve as the notch 21 and the through hole 22, respectively. Further, the lower end of the tubular film is heat-sealed under the conditions of predetermined temperature, pressure, and heating/pressurizing time, and the opening at the lower end is sealed. Here, the heat-sealed portion becomes the lower seal 18. Further, the left end of the resealing member 12 has a predetermined gap with the left fold, which is the outer peripheral edge of the tubular film, and this gap serves as the flow path portion 13.

  Next, as shown in FIG. 6D, the left and right folds, which are the left and right outer peripheral edge portions of the lower portion of the tubular film, are folded inward in a V shape so as to be recessed inward (center). The folded portion 31, which is the portion folded in the V shape, is a portion that constitutes the bottom surface portion 17 of the outer bag 10.

  Next, as shown in FIG. 6E, the upper end of the V-shaped folded portion 31 is used as a crease, and the lower seal 18 is bent so as to come to the front side. At this time, the folded portion 31 forming the bottom surface portion 17 has a hexagonal shape when viewed from the front, the lower seal 18 is positioned so as to extend in the left-right direction, and triangular tongue portions 32 are formed at the left and right ends. The tongue portion 32 is a lower portion of the folding portion 31 folded in a V shape. Then, in the left and right triangular tongue portions 32, the ends on the center side are heat-sealed under the conditions of predetermined temperature, pressure, and heating/pressurizing time. Here, the two auxiliary seals 33, which are heat-sealed portions, have a predetermined width and extend in the vertical direction so as to be orthogonal to the lower seals 18. The auxiliary seal 33 may be one that heat-bonds the entire tongue portion 32.

  Next, as shown in FIG. 6F, the left and right tongue portions 32 are bent along the auxiliary seal 33 toward the center, and the lower seal 18 of the tongue portion 32 is superposed on the lower seals 18 other than the tongue portion 32. To match. The superposed lower seals 18 are partially heat-sealed under the conditions of a predetermined temperature, pressure, and heating/pressurizing time to form the bottom portion 17 to manufacture the packaging container 1 according to the present embodiment. The overlapped lower seal 18 may be adhered using an adhesive, and the outer surface of the tongue portion 32 that is bent and overlapped may be adhered instead of the lower seal 18. Further, the auxiliary seal 33 may be omitted. However, from the standpoint of the self-supporting property of the packaging container 1, it is preferable to provide the auxiliary seal 33. The method of folding the tubular film forming the bottom portion 17 of the square bottom is not particularly limited.

  Here, the manufacturing method of the packaging container 1 is not limited to the above-mentioned method, and can be appropriately designed according to the form of the bag manufacturing apparatus. In the above-mentioned method, the tubular film shown in FIG. 6A is formed by bending and superimposing one film and heat-sealing the ends. To form a tubular film. In such a case, the film fed from the original film is bent parallel to the feeding direction and overlapped, the ends are heat-sealed to form a tubular shape, and the tubular film is cut to a predetermined length. Is formed. In addition, after the inner bag 11 and the resealing member 12 are heat-sealed to the film to be fed, the films are bent and overlapped in parallel with the feeding direction, and the ends thereof are heat-sealed to form a tubular shape, It may be cut in length. Further, the tubular film may be formed by two films, that is, the film forming the front surface portion 15 of the outer bag 10 and the film forming the back surface portion 16 of the outer bag 10. In such a case, the two films are stacked so that the sealant layers face each other, and the left and right ends are heat-sealed to form a tubular film, and a tubular film is formed on both the front surface portion 15 and the back surface portion 16. The sticker seal 19 is formed.

  Next, a method of using the packaging container 1 according to the present embodiment as an extraction container will be described in detail. FIG. 7 is a schematic diagram showing an example of an extraction process by the packaging container 1, FIG. 7A shows a state in which components are extracted from the contents, and FIG. 7B shows a state in which an extraction liquid is poured out. Be done. In the following, a case where the content is roasted and ground coffee beans, which is an example of a beverage material, is illustrated, and a method of using the packaging container 1 at the time of extracting coffee will be described. Here, the flow of coffee at the time of pouring is shown by the arrow d in FIG. 7B.

  In the packing body 50 in which the coffee beans 3 as the contents shown in FIG. 5 are housed inside the packaging container 1 and sealed, as described above, the film forming the outer bag 10 is torn from the notch 21 as the starting point. Then, the upper part of the outer bag 10 is cut off, and the packaging container 1 is opened. Next, the male member 12a and the female member 12b of the resealing member 12 are disengaged, and the opening 14a formed by unsealing and the opening 24 of the inner bag 11 are made to communicate with each other. Then, as shown in FIG. 7A, the folded portion of the packaging container 1 including the bottom portion 17 is spread out, the bottom portion 17 is placed to make the packaging container 1 self-supporting, and then the inner bag 11 is opened from the opening 14a. Pour a predetermined amount of hot water into. Since the inner bag 11 has liquid permeability, the extraction liquid obtained by extracting the coffee bean component from the hot water poured into the inner bag 11 passes through the inner bag 11 and is stored in the outer bag 10.

  Here, since the packaging container 1 can be self-supporting, the packaging container 1 can be stably placed when pouring hot water, the pouring of hot water (extraction operation) becomes easy, and the usability is good. Further, since the packaging container 1 has the gripping portion 20, it is possible to pour hot water while gripping the gripping portion 20 and assisting the self-standing of the packaging container 1, thereby preventing the packaging container 1 from unexpectedly falling. It is possible and easy to use.

  Next, the male member 12a and the female member 12b of the resealing member 12 are fitted to each other to seal the opening 24 of the inner bag 11. Then, as shown in FIG. 7B, by grasping the grasping portion 20 and tilting the packaging container 1 to the side opposite to the grasping portion 20, that is, to the left side in the figure, the outer peripheral portion on the left side of the outer bag 10 is re-assembled. Coffee can be poured out from the left side of the opening 14a via the flow path portion 13 between the left side end of the sealing member 12. Therefore, the packaging container 1 can be used as an extraction container when the components are extracted from the stored contents after being opened, which is excellent in convenience.

  Here, since the male member 12a and the female member 12b are liquid-tightly fitted to each other in the resealing member 12, the coffee beans 3 in the inner bag 11 do not jump out from the inner bag 11. Then, the coffee as the extraction liquid is poured out through the flow path portion 13 between the outer peripheral edge portion on the left side of the outer bag 10 and the left end of the resealing member 12, so that the position where the coffee is poured is Since it is regulated at a specific position, that is, on the left side of the opening 14a, it is easy to use and can be dispensed smoothly. Further, the pouring speed of coffee can be adjusted by the tilting angle of the packaging container 1, and the maximum speed thereof can be regulated to some extent by the cross-sectional area of the flow path portion 13, so that the coffee can be easily poured at a predetermined position. , Easy to use. In addition, the packaging container 1 can pour out coffee from a predetermined position without providing a separate piece of pour-out tool, and the cost can be reduced. In addition, the packaging container 1 after use as an extraction container is disposable and therefore hygienic and convenient. Further, the packaging container 1 can be discarded in a folded state as in the state before opening shown in FIG. 5, and the volume of dust can be reduced.

  Here, the configuration of the packaging container 1 is not limited to the above configuration. The packaging form of the outer bag 10 illustrated above is a square bottom bag, but it can be used by selecting from various packaging forms such as a standing pouch, a two-sided seal bag, a three-sided seal bag, a gusset bag, and a pouch. .. From the viewpoint of extraction workability, the outer bag 10 is preferably in a self-supporting form, and is a square bottom bag that can be stably self-supporting even when the rigidity of the film is lowered by being heated during extraction. More preferably.

  Further, the position of the inner bag 11 with respect to the outer bag 10 can be appropriately set according to the substance to be extracted which is the content. For example, when the substance to be extracted is one that is immersed in hot water or water during extraction, such as tea leaves or soup stock, the inner bag 11 is placed in an outer bag so that the substance to be extracted is immersed in hot water or water. It may be arranged on the lower side of the bag 10, or may be arranged so that the lower end of the inner bag 11 contacts the bottom surface portion 17 of the outer bag 10. When the content is such an object to be extracted, extraction may be performed by heating using a microwave oven. For example, when the substance to be extracted is a soup stock material, a predetermined amount of water is injected into the packaging container 1 through the opening 14a and the soup stock material is immersed in the water. Then, the inner bag 11 is resealed by the resealing member 12 and the packaging container 1 is heated in a microwave oven for a predetermined period of time to extract the components from the stock material and obtain the stock as the extract. Since the inside of the outer bag 10 in which the extract is stored communicates with the opening 14a via the flow path 13, the pressure inside the packaging container 1 does not increase excessively due to the heating of the microwave oven. Therefore, the packaging container 1 does not burst or break. Therefore, it is not necessary to make the packaging container 1 strong enough to withstand an increase in internal pressure due to heating of the microwave oven, or to provide a decompression mechanism, so that the cost can be reduced.

  The resealing member 12 is preferably arranged near the opening 14 (upper end) and extends substantially parallel to the opening 14 (upper end) and the unsealed portion 23. With such a configuration, the resealing member 12 comes along the opening 14a formed at the time of opening, and the opening 24 of the inner bag 11 is located in the vicinity of the opening 14a formed at the time of opening. Since it becomes easy to inject water and fit the male member 12a and the female member 12b, the extraction work becomes easy.

  Further, the packaging container 1 may have a configuration in which the outer bag 10 has a scale for measuring a liquid such as water or hot water used for extraction. As the scale, for example, a film forming the outer bag 10 may be transparent or translucent, and a mark printed on a print layer of the film may be used. With such a configuration, the liquid used for extraction can be measured while being poured into the packaging container 1, which is convenient.

  Further, the packaging container 1 may have a configuration as shown in FIGS. 8 and 9. Here, FIG. 8 is a schematic front view showing an example of the packaging container 2 according to another embodiment, and FIG. 9 is a schematic development view showing the outer surface side of the reinforcing member 40. In addition, the packaging container 2 is configured to further include the reinforcing member 40 in the packaging container 1 described above, and has the same configuration as the packaging container 1 except for the reinforcing member 40. The same components as those of the packaging container 1 described above are designated by the same reference numerals and the description thereof will be omitted.

  Like the packaging container 1, the packaging container 2 includes an outer bag 10, an inner bag 11, and a resealing member 12. The packaging container 2 further includes a reinforcing member 40 attached to the outer surface of the outer bag 10. The reinforcing member 40 is composed of a belt-shaped laminated body using paper as a base material, has higher rigidity and heat insulation than the film forming the outer bag 10, and has a function of reliably holding the outer bag 10 in a self-supporting state. Have.

  The laminated body forming the reinforcing member 40 may have, for example, a three-layer structure in which an outer layer, a paper base material layer, and an inner layer are laminated in order from the outer side.

The paper base layer is a main strength material, and for example, milk base paper, pure white roll paper, coated paper, kraft paper, paperboard, processed paper, and various other paper materials can be used. The basis weight of the paper material used for paper substrate layer can be appropriately determined depending on the form of the outer bag 10 to be attached, the basis weight is preferably ^{80g / m 2 ~600g / m 2} , 100g /M ^{2 to} 450 g/m ² is more preferable. The thickness is preferably 110 μm to 860 μm, more preferably 140 μm to 640 μm. The paper base layer tends to lack strength when the basis weight is too small or too thin, and the cost becomes high when the basis weight is too large or too thick.

  The outer layer and the inner layer play a role of protecting the paper base material layer, and for example, a synthetic resin film is used. As the material for the outer layer and the interior, polyester resin, polyamide resin, polyethylene resin, polypropylene resin, polycarbonate resin, polyacetal resin, fluorine resin, and various other resins can be used. The thickness of the outer layer and the inner layer is preferably 10 μm to 120 μm, and more preferably 20 μm to 60 μm.

  The laminated body forming the reinforcing member 40 may have any rigidity as long as it has higher rigidity than the film forming the outer bag 10, and its layer structure is not limited, and may be, for example, the surface of the paper base layer or the outer layer. A printing layer may be provided on the front surface or the back surface. Also, the method of laminating each layer is not limited. From the viewpoint of convenience, it is preferable that the laminated body forming the reinforcing member 40 has a structure that can be heated in a microwave oven, like the film forming the outer bag 10.

  The reinforcing member 40 has a bottom portion 41 that is rectangular in bottom view, and a pair of side portions 42 that are connected via the bottom portion 41, extend upward (opening 14), and are rectangular in front view. , Is formed in a substantially U-shape in a vertical sectional view. The lateral width of the reinforcing member 40 corresponds to the shape of the bottom surface portion 17 of the outer bag 10.

  The upper ends of the pair of side portions 42 are located below and in the vicinity of the unsealed portion 23. In addition, the pair of side portions 42 respectively have two mountain fold portions 43 that are bent so as to project outward. The two mountain folds 43 included in the side portion 42 have a predetermined interval and linearly extend from the joint with the bottom 41 to the upper end. The mountain fold portion 43 improves the rigidity of the side portion 42 against a vertical load. The number and arrangement of the mountain folds 43 are not particularly limited, and one mountain fold 43 may be formed at the lateral center of the side part 42, for example. Further, the mountain fold portion 43 may have a configuration in which the end thereof is not connected to the joint portion with the bottom portion 41 or the upper end. Further, the side portion 42 may have a configuration in which the mountain fold portion 43 is not formed. The side portion 42 may have a configuration in which the width in the left-right direction changes upward, and may have, for example, a trapezoidal shape or a triangular shape in a front view.

  At least one of the side portions 42 has a crease line 44 extending in the left-right direction at a predetermined distance from the joint portion with the bottom portion 41. The fold line 44 makes it easier to bend the laminated body forming the reinforcing member 40 so as to project inward. Examples of the fold line 44 include a fold mark formed by bending the laminated body, and a half-cut having a cut from the inner surface side of the laminated body to the middle in the thickness direction.

  The reinforcing member 40 having such a configuration is formed by bending a strip-shaped laminated body having paper as a base material at two bending portions 45 extending parallel to the lateral direction (see FIG. 9 ). The region sandwiched by the two bent portions 45 is the bottom portion 41, and the regions on the end side in the longitudinal direction of the bent portion 45 are the side portions 42, respectively. The bent portion 45 serves as a joint portion between the bottom portion 41 and the side portion 42. In addition, the reinforcing member 40 may be configured by connecting three laminated bodies corresponding to the bottom portion 41 and the pair of side portions 42.

  In the reinforcing member 40, the inner surface of the bottom portion 41 is partially adhered to the bottom surface portion 17 of the outer bag 10, and the inner surfaces of the pair of side portions 42 are respectively formed on the front surface portion 15 of the outer bag 10 and the back surface portion (not shown). It is attached to the outer bag 10 by being adhesively bonded. The method of adhering the reinforcing member 40 to the outer bag 10 is not particularly limited and may be, for example, a method using an adhesive or a method using heat fusion. Further, the reinforcing member 40 may be configured such that only the pair of side portions 42 are bonded to the front surface portion 15 and the back surface portion of the outer bag 10.

  In the packaging container 2 having such a configuration, a flat mounting surface can be secured by the bottom portion 41 of the reinforcing member 40, and the side portion 42 of the reinforcing member 40 improves the rigidity against a vertical load. Therefore, the packaging container 2 can be placed in a more stable self-supporting state, the above-described operation at the time of extraction becomes easy, and the packaging container 2 is easy to use. In addition, since the reinforcing member 40 can be grasped together with the grasping portion 20 and the packaging container 2 can be tilted when the extract is poured out, the extract can be easily poured out even at a high temperature, Easy to use. In particular, in the case where the inner bag 11 is located above the outer bag 10, the center of gravity becomes high and the self-supporting property of the outer bag 10 is likely to decrease. Is preferred. Further, the upper end of the side portion 42 is preferably positioned above the upper end (opening 24) of the inner bag 11 and below the unsealed portion 23. With such a configuration, it is possible to more effectively improve the stability of the packaging container 2 when the packaging container 2 is open without lowering the unsealing property.

  Further, since the reinforcing member 40 has the crease line 44, the side portion 42 can be bent along the crease line 44 and can be folded so that the bottom portion 41 faces the front as shown in FIG. 10. Here, FIG. 10 is a schematic front view showing a folded state of the packaging container 2 according to another embodiment. The fold line 44 corresponds to the fold line 30 shown in FIG. 4, and when the side portion 42 is folded along the fold line 44, the outer bag 10 is folded as shown in FIG. Therefore, the packaging container 2, like the packaging container 1 described above, is excellent in portability, transport efficiency, display efficiency, and the like.

  Here, the reinforcing member 40 is not limited to the above-described structure, and may be any structure as long as the outer bag 10 is self-supporting. For example, the reinforcing member 40 is formed in a cylindrical shape with a bottom so that the outer bag 10 is housed inside. It may have any configuration. The reinforcing member 40 may be composed of a member other than a laminated body having paper as a base material, such as a cardboard, a cardboard, a corrugated board, and a plate member made of a thermoplastic resin. Further, when the reinforcing member 40 is made of a material that does not affect the physical properties of the contents, the reinforcing member 40 may be attached inside the outer bag 10.

  The packaging containers 1 and 2 according to the present embodiment are not limited by size and can be applied to various sizes. For example, the volume of the packaging containers 1 and 2 may be 500 ml or more and 3000 ml or less. The volumes of the packaging containers 1 and 2 can be changed without making a large design change, the degree of freedom in design is high, and a large amount of extraction liquid can be obtained at one time. Further, since the packaging containers 1 and 2 can be folded, there is little decrease in portability, transport efficiency, display efficiency and the like due to an increase in volume.
