Description

The present invention relates to a packaging container and a filler, and more particularly to a packaging container and a filler that can also be used as an extraction container for extracting components of contents.

Beverages such as black tea, green tea, and coffee can be obtained by extracting the components from the tea leaves and coffee beans to be extracted using hot water or water. In addition, seasonings such as soup stock used in cooking can be obtained by immersing the soup stock materials such as dried bonito, dried sardines, kelp, and dried shiitake mushrooms in water or liquid seasonings and heating to extract the ingredients. Be done. Beverages, seasonings and the like obtained from such an extract may be provided in a state before extraction, that is, an extract, as well as the extract itself. If the extract is provided, the purchaser will extract the components from the extract.

Various forms have been proposed for the container for accommodating the extract to be easily extracted from the extract. For example, in the case of providing tea leaves such as black tea and green tea, a so-called tea bag type packaging container having a liquid permeability such as a non-woven fabric and in which the tea leaves as an extract are stored in a bag to which a thread is attached. Is known to be used. Black tea, green tea, etc. can be obtained by immersing this tea bag type packaging container in hot water or water. Further, when coffee beans are provided, for example, a so-called drip type coffee beans in which ground coffee beans as an extract are stored in a bag having a liquid-permeable property such as a non-woven fabric and having an openable opening. It is known to use packaging containers. Coffee can be obtained by placing this drip-type packaging container on a cup or coffee server and pouring hot water through the opened opening.

Here, in the extract such as beverages and seasonings obtained from the extract, the extracted components are oxidized in contact with oxygen, so that the flavor is impaired and the color is changed such as browning. Nutrients are lost. When the purchaser obtains the extract from the extract, the components are extracted from the extract when drinking or using, so the extract is not easily oxidized, and the flavor deteriorates or discolors. Is unlikely to occur. On the other hand, when providing the extract itself, it is important to prevent deterioration of flavor and discoloration due to oxidation, and various forms of packaging containers for preventing oxidation of the extract as contents have been studied. ing.

Further, lines III-III in FIG. 1 are straight lines passing through the resealing member 12 described later, and FIG. 3 is a horizontal 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 has a container body 10 having an opening 15 at the upper end, a liquid-permeable partition member 11, and a resealing connected to the partition member 11. A member 12 is provided. The inside of the container body 10 is configured to be divided into two chambers, a storage chamber 13 for accommodating the contents and a pouring chamber 14 communicating with the opening 15 by the partition member 11 and the resealing member 12. ing. In the following, a case where the content contained in the packaging container 1 is an extract to be extracted such as a beverage or a seasoning will be described as an example.

The container body 10 is composed of a flexible film which is a laminated body in which at least a sealant layer and a base material layer are sequentially laminated. The container body 10 is formed in a bag shape by stacking films so that the sealant layer is on the inner surface and adhering the outer peripheral edges. The sealant layer may have the property of not affecting the physical characteristics of the contents, being melted by heat, and being fused to each other. As the sealant layer, for example, a film or sheet of Linear Low Density Polyethylene (LLDPE) 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 the 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, etc. 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 Examples thereof include blended resins, and these resins can be used alone or in combination of two or more resins.

The base material layer may be any material having strength as a base material for the 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 stretched polyethylene terephthalate (BOPET: Biaxially-Oriented Polyethylene Terephthalate) film is used. The thickness of the base material layer is preferably 6 μm to 30 μm, 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-based resin, polyamide-based resin, polyethylene-based resin, polypropylene-based resin, polycarbonate-based resin, polyacetal-based resin, fluorine-based resin, and various other resins can be used.

The film, which 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, between the sealant layer and the base material layer, gas barrier property that blocks the permeation of oxygen and water vapor, light shielding property that blocks visible light and ultraviolet rays, puncture resistance, and puncture resistance An intermediate layer for adding flexibility, heat resistance, and the like may be further provided, and the intermediate layer may be configured in multiple layers. Examples of the layer that imparts gas barrier properties include a vapor-deposited film such as aluminum oxide and silicon oxide, and examples of the layer that imparts puncture resistance include a polyamide-based resin film. Further, an outer layer may be provided on the surface of the base material layer. The outer layer serves to protect the packaging bag, and a synthetic resin film can be used, for example, as in the above-mentioned base material layer.

The laminating method of each layer is not limited, and for example, laminating can be performed by dry lamination with a polyurethane adhesive. From the viewpoint of convenience, it is preferable that the film constituting the container body 10 has a transparency such that the contents can be visually recognized and can be heated in a microwave oven. The layer structure of such a film is, for example, linear low-density polyethylene (60 μm: sealant layer) / aluminum oxide vapor-deposited film (20 nm: intermediate layer) / polyethylene terephthalate (12 μm: base material layer). Can be done.

The container body 10 is formed from a film as a laminated body having the above-mentioned layer structure. The container body 10 is formed in a bag shape by bending and superimposing the films so that the sealant layer is on the inner surface side and adhering the outer peripheral edges. 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 is used as the sealant layer in the laminated film, for example, a heat-sealing method can be easily produced, which is preferable.

The container body 10 is a square bottom bag having an upper end opening 15, a front surface portion 16, a back surface portion 17, and a bottom surface portion 18, and the bottom surface portion 18 is flat and rectangular in bottom view. The bottom surface portion 18 is used as a mounting surface so that it can stand on its own. Although the details will be described later, the container body 10 is formed by folding the lower part of the rectangular packaging bag in front view having an opening 15 at the upper end. The surface portion 16 is composed of one side of the folded and laminated films, and is located on the front side of FIG. The back surface portion 17 is formed on the other side of the folded and superposed films, and is located on the back side of FIG. The container body 10 is configured so that the contents can be sealed and accommodated by sealing the opening 15.

The container body 10 has a side seal 19 and a lower seal 20 as outer peripheral edges to which the laminated films are adhered, a grip portion 21 provided on the upper portion of the side seal 19, and a notch provided on the grip portion 21. It also has 22, a through hole 23, a planned opening portion 24, and the like.

The side seal 19 and the lower seal 20 are formed by heat-sealing the outer peripheral edges of films in which the sealant layer is on the inner surface side and the films are bent and overlapped so that the sealant layers face each other, and have a predetermined width. And extends along the outer peripheral edge of the film. The side seal 19 and the lower seal 20 have adhesive strength capable of holding the extract inside during extraction, which will be described later.

The side seal 19 has a grip portion 21 whose width is widened at the upper part. That is, the grip portion 21 is a portion where the width of the side seal 19 is expanded inward, extends to the upper end of the container body 10, and has an area that can be pinched by at least two fingers.

The grip portion 21 of the side seal 19 has a notch 22 as an opening means that triggers tearing of the film constituting the container body 10. The notch 22 is a V-shaped notch extending inward from the outer end of the side seal 19, has a predetermined distance from the upper end of the container body 10, and is above the resealing member 12 (opening 15). It is located on the side). Further, the grip portion 21 has a circular through hole 23 penetrating from the front surface side to the back surface side.

The grip portion 21 having the widened width of the side seal 19 has a shape in which the width gradually increases from the lower side to the upper side, but the shape, arrangement, and number thereof are not limited, and the container main body. It can be appropriately set according to the form of 10. Further, the notch 22 may have a structure that 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 23 are not particularly limited, and may be, for example, a polygonal shape or an elliptical shape. Further, the notch 22 and the through hole 23 may be formed in the side seal 19 different from the grip portion 21.

The planned opening portion 24 has a predetermined distance from the upper end (opening 15) of the container body 10 and extends from the notch 22 in the left-right direction along the upper end. The planned opening portion 24 is a weakening line in which the strength of the film constituting the container main body 10 is weakened, and is formed on the front surface portion 16 and the back surface portion 17. The scheduled opening portion 24 has a function of guiding a crevice that propagates when the film constituting the container body 10 is torn from the notch 22 onto the scheduled opening portion 24. Examples of the weakening line include a half-cut having a cut from the inner surface side or the outer surface side of the film to the middle in the thickness direction. The through hole 23 is preferably provided at a position where it does not intersect with the planned opening portion 24, and does not hinder the tearing of the film starting from the notch 22.

The liquid-permeable partition member 11 is a flexible strip-shaped sheet and is attached to the inside of the container body 10. As the partition member 11, a material having flexibility and not affecting the physical characteristics of the contents, for example, a material such as pulp, cotton, hemp, silk, synthetic resin, etc., alone or a mixture of two or more thereof is used. A woven fabric or a non-woven fabric composed of the above can be used. The partition member 11 may be a synthetic resin film having a large number of fine through holes, as long as it has a liquid permeability and does not allow the contents (solid matter) contained in the container to permeate. , Its composition, material, thickness, water permeability, etc. are appropriately set according to the contents. From the viewpoint of convenience, it is preferable that the partition member 11 has a configuration capable of being heated in a microwave oven, similarly to the film constituting the container body 10.

The band-shaped partition member 11 extends from, for example, the lower seal 20 which is an outer peripheral edge portion other than the opening 15 of the container body 10 toward the opening 15. More specifically, the partition member 11 extends from the center of the bottom surface portion 18 of the container body 10 along the side facing the side seal 19 and along the inner surface of the container body 10 on the left side in the drawing. Both ends in the width direction, which is the lateral direction of the strip-shaped partition member 11, are adhered to the inner surface of the front surface portion 16 and the inner surface of the back surface portion 17, respectively, along the longitudinal direction. The end portion of the partition member 11 in the lower seal 20 is adhered while being sandwiched between the laminated films. The other end of the partition member 11 is located near the opening 15 and is located on the side facing the side seal 19 and on the left side in the drawing. The partition member 11 is interposed between the front surface portion 16 and the back surface portion 17, and is configured to partition the inside of the container body 10 into two regions. From the viewpoint of openability, the other end of the partition member 11 is preferably located below the planned opening portion 24 (on the side of the bottom surface portion 18), and it is possible to prevent the partition member 11 from opening poorly.

The partition member 11 may be adhered to the container body 10 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 which is the laminate constituting the container body 10, the method by heat fusion can be easily produced, which is preferable. Therefore, the partition member 11 is preferably configured so that it can be heat-sealed to the film constituting the container body 10, for example, low density polyethylene, medium density polyethylene, high density polyethylene, linear low density polyethylene, and the like. Examples thereof include a polyolefin resin such as polypropylene and a non-woven fabric composed of a resin composed of a mixture thereof.

The resealing member 12 is a so-called zipper composed of a male member 12a and a female member 12b that are liquid-tightly fitted to each other, and is attached to the inside of the container body 10. The resealing member 12 extends in the left-right direction from the side seal 19 which is an outer peripheral edge portion other than the opening 15 of the container body 10, and is connected to the partition member 11. The male member 12a of the resealing member 12 is adhered to the inner surface of the surface portion 16 with the convex fitting portion (not shown) facing inward. The female member 12b of the resealing member 12 is adhered to the inner surface of the back surface portion 17 with the concave fitting portion (not shown) that fits the convex fitting portion in a liquid-tight manner facing inward. The end portion of the resealing member 12 in the side seal 19 is sandwiched between the overlaid films and is adhered in the side seal 19. The end portion of the resealing member 12 may be joined to the side seal 19, and the side seal 19 has a protruding portion that protrudes inward and joins the end portion of the resealing member 12. You may. The other end side of the resealing member 12 is adhered to the partition member 11, and the tip thereof is adhered while being sandwiched between the partition members 11. That is, both ends of the resealing member 12 are in a state in which the male member 12a and the female member 12b are not disengaged. Then, in the resealing member 12, by fitting the male member 12a and the female member 12b, the inner surface of the front surface portion 16 and the inner surface of the back surface portion 17 can be liquid-tightly joined, and the male member 12a and the female member 12b are fitted. By removing the case, the inner surface of the front surface portion 16 and the inner surface of the back surface portion 17 can be separated from each other.

With the resealing member 12 having such a configuration and the partition member 11 to which the resealing member 12 is connected, the inside of the container body 10 is a storage chamber 13 for accommodating the contents and a pouring chamber 14 communicating with the opening 15. It is divided into two rooms. Therefore, the storage chamber 13 partitioned by the partition member 11 and the resealing member 12 is configured to be resealable by the resealing member 12. That is, the accommodation chamber 13 can be put into an opened state communicating with the opening 15 by disengaging the male member 12a and the female member 12b of the resealing member 12, and the male member 12a and the female member of the resealing member 12 can be opened. By fitting the 12b, it is possible to put the resealed state in which the communication with the opening 15 is cut off.

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. A system resin, a fluorine system resin, and various other resins can be used. The resealing member 12 may be adhered to the container body 10 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 which is the laminate constituting the container body 10, the method by heat fusion can be easily produced, which is preferable. Therefore, the resealing member 12 is preferably made of a material that can be heat-sealed to the film constituting the container body 10, for example, low density polyethylene, medium density polyethylene, high density polyethylene, linear low density. Examples thereof include polyolefin resins such as polyethylene and polypropylene, and resins composed of mixtures thereof. From the viewpoint of convenience, it is preferable that the resealing member 12 has a configuration capable of being heated in a microwave oven, similarly to the film constituting the container body 10.

The resealing member 12 is not limited to the configuration in which the male member 12a and the female member 12b are fitted together, but the inner surface of the front surface portion 16 and the inner surface of the back surface portion 17 are liquid-tightly joined. The storage chamber 13 may be separated from each other and may be in a resealed state in which communication with the opening 15 is cut off and in an opened state in which communication with the opening 15 is cut off. For example, the inner surface of the front surface portion 16 and the inner surface of the back surface portion 17 may be coated with an adhesive capable of peeling and re-adhesion in a band shape.

After the contents are stored through the opening 15 in the storage chamber 13 of the container body 10 of the packaging container 1 configured as described above, the opening 15 is sealed by the upper seal 25 as a sealing portion to form the packaging container 1. It is sealed and the filler 50 according to the present embodiment is produced (see FIG. 4). That is, the filler 50 includes a packaging container 1 further including an upper seal 25 that seals the opening 15 of the container body 10, and the contents housed in the storage chamber 13.

The upper seal 25 is formed by heat-sealing films laminated so that the sealant layers face each other, similarly to the side seal 19 and the lower seal 20 described above. That is, the inner surface of the front surface portion 16 and the inner surface of the back surface portion 17 are heat-sealed. The upper seal 25 has a predetermined width and extends in the left-right direction along the upper end (opening 15) of the container body 10. The upper seal 25 is located above the planned opening portion 24 and is configured not to include the scheduled opening portion 24. The upper seal 25 can maintain airtightness and prevent quality deterioration due to oxidation of the contents. The above-mentioned through hole 23 may be formed in the upper seal 25.

The extract to be extracted as the content contained in the packaging container 1 may be any one that extracts beverages, seasonings, etc., for example, beverage materials such as tea leaves and ground coffee beans used for extracting beverages, and beverage materials such as ground coffee beans. It can be used as a soup stock material such as dried bonito, boiled dried sardines, kelp, and dried shiitake mushrooms used for extracting soup stock. In the filler 50 shown in FIGS. 4 and 5, kelp 3 which is a soup stock material is contained as the content.

The packaging container 1 having such a configuration is opened by tearing the film constituting the container body 10 from the notch 22 and cutting off the upper part of the container body 10. Here, since the container body 10 has a notch 22 and a planned opening portion 24, the packaging container 1 can be easily opened. Further, since the crevice that propagates when torn is guided to the planned opening portion 24, it does not propagate to the joint portion of the partition member 11 and the resealing member 12 with the film, and a defective opening can be prevented. From the viewpoint of openability, the container body 10 preferably has a notch 22 and a planned opening portion 24, but the container body 10 of the packaging container 1 does not have to have the notch 22 and the scheduled opening portion 24, for example, the surface. The package may be opened by separating the portion 16 and the back surface portion 17 and peeling off the upper seal 25 as the sealing portion.

Further, since the container body 10 and the partition member 11 of the packaging container 1 have flexibility, the packaging container 1 may be placed at the portion indicated by the folding line 26 of the alternate long and short dash line in FIG. 4, for example, depending on the contents to be accommodated. It can be folded so that the bottom surface portion 18 faces the front as shown in FIG. Therefore, the volume of the filler 50 can be reduced, and the portability is excellent. Further, since the volume and weight are reduced as compared with the case where the extract is contained in the container, the transport efficiency is good. Further, since the packaging container 1 has the through hole 23, it can be hung and displayed even in a state where it cannot stand on its own 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 for extracting components from the contained contents after being opened. Further, since the packaging container 1 after use as an extraction container can be disposable, it is hygienic and excellent in convenience. Further, the packaging container 1 can be disposed of in a folded state in the same manner as in the state before opening shown in FIG. 5, and the volume of dust can be reduced.

Next, the manufacturing method of the packaging container 1 according to the present 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. In addition, in FIGS. 6D to 6F, the description of the partition member 11 and the resealing member 12 is omitted. First, as shown in FIG. 6A, a single film constituting the container body 10, a strip-shaped partition member 11, and a resealing member 12 composed of a male member 12a and a female member 12b are prepared. .. One film is arranged so that the sealant layer is on the front side, and is folded so as to be recessed in a V shape toward the back side in parallel with the vertical direction at the center in the left-right direction. Here, with the V-shaped folded portion as a boundary, the film on one side, the left side in the drawing, constitutes the front surface portion 16, and the film on the other side, the right side in the drawing, is the back surface portion 17. It becomes a film that constitutes. 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 planned opening portion 24.

The overlapped lower seal 20 may be adhered using an adhesive, and the outer surface of the bent portion 27 which is bent and overlapped may be adhered instead of the lower seal 20. Further, the auxiliary seal 28 may be omitted. However, from the viewpoint of the independence of the packaging container 1, it is preferable to provide the auxiliary seal 28.

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 making device. In the above method, the partition member 11 and the resealing member 12 are attached to one film constituting the container main body 10, but for example, the partition member 11 and the resealing member 11 are reattached to the film unwound from the raw film of the roll-shaped film. It may be a method of attaching the sealing member 12. In such a case, the V-shaped fold shown in FIG. 6A is formed so as to extend parallel to the feeding direction of the film fed from the original fabric. Then, the partition member 11 and the resealing member 12 are heat-sealed, the film is bent and overlapped in parallel with the feeding direction along the V-shaped folding, and the ends thereof are heat-sealed to form a tubular shape. By cutting to a predetermined length, the tubular film shown in FIG. 6B is formed.

Further, one film constituting the container body 10 is folded in half and overlapped, and the ends are heat-sealed to form a tubular film, and the partition member 11 and the resealing member 12 are inside the tubular film. It may be the method of attaching. The order in which the partition member 11 and the reseal member 12 are attached to the tubular film is not particularly limited. For example, after one end of the reseal member 12 is heat-sealed to the partition member 11, the partition member 11 is attached. And the resealing member 12 may be heat-sealed inside the tubular film.

Further, the container body 10 may be composed of two films, a film forming the front surface portion 16 and a film forming the back surface portion 17. In such a case, the two films are overlapped so that the sealant layers face each other, and the left and right ends are heat-sealed to form a tubular film, and the side seals 19 are formed on the left and right ends.

Further, the heat fusion of the lower end of the tubular film shown in FIG. 6C may be performed in a state where the side seal 19 is located at the end in the left-right direction, that is, in a state shown in FIG. 6B. In the case of such a configuration, the method of folding the tubular film for forming the bottom surface portion 18 is different. Although the description by illustration is omitted, the lower part of the tubular film, the right side on which the side seal 19 is located and the left side on the opposite side, are V-shaped in front view so as to be recessed inward (center). Fold it in. The upper end of the V-shaped folded portion is made a crease, and the lower seal 20 is bent so as to come to the front side. At this time, the portion forming the bottom surface portion 18 has a hexagonal shape when viewed from the front, the lower seal 20 is positioned so as to extend in the left-right direction, and a triangular tongue portion is formed at the left and right end portions. The tongue part is the lower part when folded into a V shape. The bottom surface portion 18 is formed by folding back the left and right tongue portions to the center side and partially adhering the overlapped portions. The method of folding the tubular film forming the bottom surface portion 18 of the square bottom is not particularly limited.

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 view showing an example of the extraction process by the packaging container 1, FIG. 7A shows a state of extracting components from the contents, and FIG. 7B shows a state of pouring out an extract. Is done. In the following, the case where the content is kelp, which is an example of the soup stock material, will be illustrated, and the method of using the packaging container 1 when extracting the soup stock will be described. Here, in FIG. 7B, the flow of the soup stock at the time of pouring is indicated by the arrow d.

As the content shown in FIG. 5, in the filler 50 in which the kelp 3 is housed inside the packaging container 1 and then sealed, as described above, the film constituting the container body 10 is torn from the notch 22 as a starting point. The upper part of the container body 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 15a formed by opening is communicated with the storage chamber 13. Then, as shown in FIG. 7A, the folded portion of the packaging container 1 including the bottom surface portion 18 is expanded, the bottom surface portion 18 is placed on the packaging container 1 to make the packaging container 1 independent, and then the storage chamber 13 is opened through the opening 15a. Inject a predetermined amount of water into the container. Since the partition member 11 has liquid permeability, the water injected into the storage chamber 13 permeates the partition member 11 and spreads to the pouring chamber 14.

Here, since the packaging container 1 is self-supporting, the packaging container 1 can be stably placed when water is injected, and water injection (extraction operation) is facilitated, which is convenient. Further, since the packaging container 1 has the grip portion 21, water can be injected while gripping the grip portion 21 and assisting the independence of the packaging container 1 to prevent the packaging container 1 from unexpectedly tipping over. It is easy to use.

Next, the male member 12a and the female member 12b of the resealing member 12 are fitted, the communication between the opening 15a and the storage chamber 13 is cut off, and the entire packaging container 1 is heated in a microwave oven for a predetermined time. Here, the opening 15a and the pouring chamber 14 communicate with each other, and the storage chamber 13 and the pouring chamber 14 are partially partitioned by a liquid-permeable partition member 11, so that the container is heated by heating in a microwave oven. The pressure inside the packaging container 1 does not increase excessively, and the packaging container 1 does not burst or break. Therefore, it is not necessary to make the packaging container 1 strong enough to withstand the increase in internal pressure due to heating of the microwave oven, or to provide a decompression mechanism, so that the cost can be reduced. By heating in this microwave oven, the components are extracted from the kelp 3 as the content, and the soup stock as the extract is obtained. When the content is, for example, tea leaves, it is possible to obtain tea or the like as an extract from which the components are extracted by using water or hot water without heating in a microwave oven.

Then, as shown in FIG. 7B, the soup stock can be poured out from the left side of the opening 15a by gripping the grip portion 21 and tilting the packaging container 1 to the side of the partition member 11 or to the left side in the drawing. ..

Will be done. Since the partition member 11 extends along the inner surface of the container body 10 on the left side opposite to the grip portion 21, the pouring of the soup stock is restricted to the left side of the opening 15a, which is convenient. .. The soup stock pouring speed can be adjusted by the tilt angle of the packaging container 1, and the maximum speed is determined by the cross-sectional area of the pouring chamber 14 at the end of the resealing member 12 on the side where it is joined to the partition member 11. Since it can be regulated to some extent, it is easy to pour the soup stock into a predetermined position and it is easy to use. In addition, the packaging container 1 can dispense the soup stock from a predetermined position without providing a dispensing tool of a separate member, and the cost can be reduced. Further, since the soup stock in the storage chamber 13 is poured out after passing through the partition member 11, the soup stock is not poured out in a state where the kelp 3 as an extract is mixed, which is convenient. Further, since the packaging container 1 after use as an extraction container can be disposable, it is hygienic and excellent in convenience. Further, the packaging container 1 can be disposed of in a folded state in the same manner 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 container body 10 exemplified above is a square bottom bag, but it can be selected and used from various packaging forms such as a standing pouch, a two-way seal bag, a three-way seal bag, a gusset bag, and a gassho bag. ..

The structure may extend from the crease of the film which is the joint portion with the portion 17. Further, the resealing member 12 may be connected to the partition member 11 via a connection seal in which the inner surface of the front surface portion 16 and the inner surface of the back surface portion 17 are heat-sealed. From the viewpoint of extraction workability, the partition member 11 is preferably arranged so that the end (upper end) on the side of the opening 15 is located near the outer peripheral edge portion on the side facing the grip portion 21. With such a configuration, the flow of the dispensed liquid at the time of pouring is stable, and the extraction work becomes easy. Further, it is preferable that the resealing member 12 is arranged so as to extend in the vicinity of the opening 15 (upper end) and substantially parallel to the opening 15 (upper end) and the planned opening portion 24. With such a configuration, the resealing member 12 is aligned with the opening 15a formed at the time of opening, so that the male member 12a can be easily fitted to the female member 12b, and the extraction work becomes easy.

Further, the packaging container 1 may have a structure in which the container body 10 has a scale for measuring a liquid such as water or hot water used for extraction. Examples of the scale include making the film constituting the container body 10 transparent or translucent, and markings printed on the print layer of this film.

Has.

The laminated body constituting the reinforcing member 30 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 this order from the outside.

The paper base material 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 container body 10 to be attached, the basis weight is preferably ^{80g / m 2 ~600g / m 2} , 100g More preferably, it is / m ^{2 to} 450 g / m ² . The thickness is preferably 110 μm to 860 μm, more preferably 140 μm to 640 μm. If the basis weight of the paper substrate layer is too small or too thin, the strength tends to be insufficient, and if the basis weight is too large or too thick, the cost increases.

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-based resin, polyamide-based resin, polyethylene-based resin, polypropylene-based resin, polycarbonate-based resin, polyacetal-based resin, fluorine-based 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, more preferably 20 μm to 60 μm.
