Description

Technical Field

[0001] The present invention relates to a packaging container.

Background Art

[0002] Conventionally, when taking out a predetermined amount of contents from a packaging container that houses contents such as powders, granules, and liquids, a measuring spoon or the like has been necessary. In this case, a measuring spoon is inserted through the opening of the packaging container to scoop up the contents, and the surface is scraped off to take out a predetermined amount of the contents. Taking the measuring spoon in and out of the packaging bag in this way is not hygienically preferable, and also, a large amount of work is required to take out a predetermined amount of the contents, which is time-consuming. As a method other than using a measuring spoon, it is also conceivable to use a single-use individual package packaged in a predetermined amount. However, the individual package tends to increase the cost of the packaging material, and also increases the amount of waste generated, having a large impact on the environment.

[0016] Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings and the like.

[0017] (First Embodiment) FIG. 1 is a plan view of the packaging container 1 of the first embodiment. In FIG. 1, the sealed area is shown by hatching, and the same applies to the drawings of other embodiments. FIG. 2 is a side view and a partial cross-sectional view of the packaging container 1 in FIG. 1. FIG. 2(A) is a side view of the packaging container 1, FIG. 2(B) is a partial cross-sectional view of the packaging container 1 cut at the position of arrow B-B in FIG. 1, and FIG. 2(C) is a partial cross-sectional view of the packaging container 1 cut at the position of arrow C-C in FIG. 1.

FIG. 4 is a plan view showing the packaging container 1 in a state where the lower seal portion is unsealed, and shows the state of the packaging container 1 before storing the contents in the storage portion 10. Note that, including FIGS. 1 to 4 shown below, each of the figures shown below is a schematic diagram, and the size and shape of each part are exaggerated or omitted as appropriate for easy understanding. Also, although the packaging container 1 in FIG. 1 and each of the figures shown below is illustrated as being formed of a transparent laminated film, it is not limited to being formed of a transparent laminated film. Further, in FIGS. 1, 3 to 4, and each of the figures showing the packaging containers after FIG. 7, illustration of the display portion 50 and the gripping instruction portion 51 described later is omitted. Also, in the following description, specific numerical values, shapes, materials, etc. are shown for the description, but these can be changed as appropriate.

[0018] The packaging container 1 of the present embodiment is, for example, distributed and sold in a state of containing various contents, and after opening, a part of the contents can be taken out and the remaining can be resealed while being contained in the container. Further, the packaging container 1 of the present embodiment has a function of measuring and taking out a predetermined amount of the contained contents. As shown in FIG. 1, the packaging container 1 includes a storage portion (second storage portion) 10 that stores the contents, a measurement portion (first storage portion) 20 that stores the measured contents, a partition portion 30 that partitions between the storage portion 10 and the measurement portion 20, and a chuck portion (opening / closing portion) 40 provided in the measurement portion 20. The storage portion 10 is a portion that stores the contents to be stored in the packaging container 1, and is provided below (second edge side) the measurement portion 20 of the packaging container 1. The measurement portion 20 is provided at a position above (first edge side) the storage portion 10, and is a portion that stores a predetermined amount of the contents that has moved from the storage portion 10 through a hole portion 32 (described later) provided in the partition portion 30.

[0019] (Container main body portion) As shown in FIG. 1, the container body 2 of the packaging container 1 is a pouch-shaped container in the form of a bag, and is composed of a flexible laminated film. The laminated film constituting the container body 2 includes a surface film 11 (packaging material) forming the front surface, a back film 12 (packaging material) forming the back surface, and a partition film 13 (sheet-like member) constituting the partition portion 30. In the present embodiment, the surface film 11 and the back film 12 are formed by a first laminated film 160, and the partition film 13 is formed by a second laminated film 170 (details will be described later).

[0020] The surface film 11 and the back film 12 of the present embodiment are composed of a substantially rectangular laminated film. The substantially rectangular shape is not limited to a geometric rectangle, and includes a shape that is recognized as a rectangle in an overall view. For example, one or more of the side edges, bottom edge, or top edge may include a curved portion. Also, the corners of the laminated film may be rounded in an outwardly convex arc shape. In the present embodiment, the container body 2 is formed by the individually configured surface film 11, back film 12, and partition film 13. At the upper part 3 of the container body 2, the upper part of the surface film 11 and the upper part of the back film 12 are joined by heat sealing (thermal welding). By this joining, an upper seal portion 101 is formed at the upper part 3 of the container body 2 as a seal portion that joins the upper part of the surface film 11 and the upper part of the back film 12.

[0021] At the side part 4 of the container body 2, the side part of the surface film 11 and the side part of the back film 12 are joined by heat sealing. By this joining, side seal portions 103 are formed at the left and right side parts 4 (the third edge, the fourth edge) of the container body 2 as seal portions that join the side part of the surface film 11 and the side part of the back film 12. Note that the left and right side seal portions 103 are formed such that their upper ends are continuous with the upper seal portion 101, and their lower end vicinities are formed such that they are continuous with a lower seal portion 102 described later.

[0022] The side seal portion 103 is provided with a notch 7 for separating the upper seal portion 101 of the container body portion 2. The notch 7 is provided for separating the upper seal portion 101 from the container body portion 2 to open the metering portion 20 of the packaging container 1. The notch 7 is a cut provided on the upper end side of the side seal portion 103 and below the upper seal portion 101, and is provided so as not to penetrate from the edge of the side portion 4 of the container body portion 2 into the metering portion 20.

[0023] The chuck portion 40 is provided above the metering portion 20 and below the notch 7, and is a portion that enables resealing after opening, and can be constituted by a chuck tape. The chuck portion 40 extends along the upper portion 3, and as a part of the chuck tape, as shown in Fig. 2(C), it has a first fitting portion (female portion) 41 and a second fitting portion (male portion) 42. Among the chuck tapes, the portion provided on the inner surface of the surface film 11 is the first fitting portion 41. Also, among the chuck tapes, the portion provided on the inner surface of the back film 12 is the second fitting portion 42. The chuck portion 40 can be freely opened and closed by the fitting and release of the first fitting portion 41 and the second fitting portion 42.

[0024] In the lower portion 5 of the container body portion 2, the lower portion of the surface film 11 and the lower portion of the back film 12 are joined by heat sealing (thermal welding). By this joining, a lower seal portion 102 is formed in the lower portion 5 of the container body portion 2 as a seal portion for joining the lower portion of the surface film 11 and the lower portion of the back film 12. Note that, as shown in Fig. 4, before the packaging container 1 stores the content in the storage portion 10, the lower portion 5 is not joined, and after storing the content in the storage portion 10, the lower seal planned portion 102' provided in the lower portion 5 is heat sealed, whereby the lower portion 5 is joined and the lower seal portion 102 is formed.

[0025] As shown in FIGS. 1 to 3, the partition portion 30 is formed by a partition film 13 folded in two, and is joined to the front surface film 11 and the back surface film 12 such that the fold portion 31 is positioned on the upper side (first edge side). More specifically, for the partition film 13 folded in two, the peripheral portion of the first half excluding the fold portion 31 is joined to the front surface film 11 by heat sealing, and the peripheral portion of the second half excluding the fold portion 31 is joined to the back surface film 12 by heat sealing. By these joints, a partition seal portion 104 is formed between the peripheral portion of the first half excluding the fold portion 31 of the partition film 13 and the front surface film 11, and between the peripheral portion of the second half excluding the fold portion 31 of the partition film 13 and the back surface film 12. Thereby, a gusset-shaped partition portion 30 is disposed between the front surface film 11 and the back surface film 12, and a storage portion 10 is formed in the lower part (second edge side) of the container body portion 2 with the partition portion 30 as a boundary, and a measuring portion 20 is formed in the upper part (first edge side) of the container body portion 2.

[0026] Here, in the left-right direction (width direction) of the container body portion 2, the width W2 of the partition film 13 is larger than the width W1 of the storage portion 10 and smaller than the width W of the container body portion 2. That is, it has the relationship of W>W2>W1. Therefore, as shown in FIGS. 1 and 3, the partition film 13 is disposed in a folded state with a predetermined gap evenly opened with respect to the side edges of the front surface film 11 and the back surface film 12. Therefore, as shown in the cross-sectional view of FIG. 2(B), each side edge of the first half and the second half of the partition film 13 folded in two is joined to the front surface film 11 and the back surface film 12 by the partition seal portion 104, respectively. As shown in the side view of FIG. 2(A), the side edge portions where the partition film 13 between the front surface film 11 and the back surface film 12 does not overlap are directly joined by the side seal portion 103 between the front surface film 11 and the back surface film 12. In the region where the storage portion 10 and the metering portion 20 of the container main body portion 2 are formed, as shown in FIG. 2(C), the partition film 13 has only the lower end edges of the first half and the second half joined to the front surface film 11 and the back surface film 12 by the partition seal portions 104, respectively. Further, in the folded partition portion 30, the inner surfaces of the first half and the second half of the partition film 13 facing each other are not joined.

[0027] In the partition portion 30, a hole portion 32 penetrating the storage portion 10 and the metering portion 20 is provided at one end portion or both end portions in the width direction (left - right direction) of the container main body portion 2. In the present embodiment, as shown in FIG. 1, the hole portion 32 is provided at the left end portion in the width direction of the packaging container 1 so as to overlap the fold line portion 31 of the partition film 13. By providing the hole portion 32 so as to overlap the fold line portion 31 in this way, when the partition portion 30 is in a folded state, the opening area of the hole portion 32 can be minimized as much as possible, and when the folded partition portion 30 is opened, the opening area of the hole portion 32 can be widened. In the present embodiment, an example is shown in which the hole portion 32 is formed in a circular shape, but it is not limited thereto, and it may be formed in a shape other than a circle, for example, an ellipse, a rectangle, a polygon, etc. Further, in the present embodiment, an example is shown in which one hole portion 32 is provided in the partition portion 30, but it is not limited thereto, and a plurality of hole portions 32 may be provided.

[0028] The hole portion 32 is preferably provided in a region from the end portion in the width direction of the partition portion 30 to a distance of 1 / 3 or less of the width W2 of the partition portion 30. Thereby, the hole portion 32 provided in the partition portion 30 can be arranged in the vicinity of the side seal portion 103, making it easy to move the contents stored in the storage portion 10 to the metering portion 20, and when taking out the contents from the metering portion 20 to the outside of the packaging container 1, it is possible to make it difficult to open the hole portion 32, and it is possible to significantly suppress the remaining contents in the storage portion 10 from leaking to the metering portion 20 side.

[0029] Further, the hole portion 32 has an opening area of 315 mm 2The following are desirable. If the opening area of the hole portion 32 is larger than 315 mm 2 when, in the method of using the packaging container described later, the content moved to the measuring portion 20 is likely to return to the accommodating portion 10 again, which is not desirable. Further, the hole portion 32 desirably has an opening area of 78 mm 2 or more. If the opening area of the hole is less than 78 mm 2 it is not desirable because the hole is too small and it becomes difficult or time-consuming to move the content accommodated in the accommodating portion 10 to the measuring portion 20. For example, when one circular hole portion 32 is provided in the partition portion 30 as in the present embodiment, its diameter is desirably 20 mm or less. When a plurality of hole portions 32 are provided in the partition portion 30, it is desirable that the total opening area of the plurality of holes is within the above range.

[0030] (Laminated film) Next, the laminated film used for the packaging container 1 will be described. FIG. 5 is an example of a cross-sectional view of the laminated film used for the packaging container 1 of the present embodiment. FIG. 5(A) is a cross-sectional view showing an example of the layer structure of the first laminated film 160 used for the front surface film 11 and the back surface film 12, and FIG. 5(B) is a cross-sectional view showing an example of the layer structure of the second laminated film 170 used for the partition film 13. The front surface film 11 and the back surface film 12 constituting the packaging container 1 are made of the first laminated film 160, and the partition film 13 is made of the second laminated film 170. As described above, the packaging container 1 is formed into a bag by heat-sealing the first laminated film 160 forming a pair of the front surface film 11 and the back surface film 12 and the second laminated film 170 forming the partition film 13.

[0031] Therefore, the first laminated film 160 is provided with at least a base material layer 161 and a sealant layer 162 having sealability on the portion on the inner side of the container. Further, the second laminated film 170 is provided with at least a base material layer 171 and a sealant layer 172 having sealability. The first laminated film 160 and the second laminated film 170 may include a plurality of the above-described base material layers, or the sealant layer may be composed of a plurality of layers. In the packaging container 1 of the present embodiment, in the first laminated film 160, the base material layer 161 serving as a base base material is provided in a portion on the outer side of the container with respect to the sealant layer 162. The first laminated film 160 may be configured to include other layers such as a pattern layer, a gas barrier layer, and a light-shielding layer in order to impart various functions according to the application. Further, in the packaging container 1 of the present embodiment, the second laminated film 170 is arranged such that the sealant layer 172 is located closer to the metering unit 20 side of the packaging container 1 than the base material layer 171. That is, the sealant layer 172 is located on the outer surface (the surface on the side joined to the front surface film 11 and the back surface film 12) of the two-folded partition film 13.

[0032] (First laminated film) As the base material layer 161, for example, a stretched polyethylene terephthalate (PET) film, a silica-deposited stretched polyethylene terephthalate (PET) film, an alumina-deposited stretched polyethylene terephthalate film, a stretched polyamide film, a stretched polypropylene film, or a composite film obtained by laminating two or more of these films can be used.

[0033] Preferably, the base material layer 161 is biaxially stretched. As a result, the molecules forming the base material layer 161 are aligned in the stretching direction by the stretching treatment, and the base material layer 161 exhibits excellent dimensional stability. In addition, the biaxial stretching treatment can impart an easy-openability to the base material layer 161.

[0034] The thickness of such a base material layer 161 is formed to be, for example, about 8 μm to 30 μm. Note that the base material layer 161 of the present embodiment also functions as the outermost layer of the laminated film 160 when the laminated film 160 is formed into a bag to form the container main body 2.

[0035] Further, a pattern layer 164 including a pattern may be laminated as another layer on the surface of the base material layer 161 on the inner side or the outer side of the container. Here, the pattern refers to a recording target in various forms that can be recorded or printed on the base material layer 161, and is not particularly limited, widely including figures, characters, patterns, patterns, symbols, motifs, marks, etc. Note that the pattern layer 164 is laminated on the base material layer 161 as necessary, and the pattern layer may not be provided on the base material layer 161. In that case, for example, various displays may be made by attaching a label.

[0036] The pattern layer 164 may be provided on the inner surface of the base material layer 161 instead of the outer surface of the base material layer 161 on the outer side of the container. In this case, since the pattern layer 164 is excellent in abrasion resistance, it can effectively prevent disappearance due to rubbing or the like, and can also effectively prevent forgery of the pattern. Further, when forming a bag to make the packaging container 1, it is preferable that the base material layer 161 has transparency so that the pattern layer 164 laminated on the inner surface of the base material layer 161 can be visually recognized through the base material layer 161.

[0037] As described above, the sealant layer 162 is provided to seal the opposing edge portions by heat-sealing the vicinity of the opposing edge portions where the two laminated films 160 are overlapped. Further, in the present embodiment, the sealant layer 162 is disposed on the innermost side of the laminated film 160 when forming a bag to make the container body portion 2.

[0038] As such a sealant layer 162, a film made of a polyolefin resin such as polyethylene, polypropylene, ethylene-vinyl acetate copolymer, ethylene-propylene block copolymer, and a conventionally known easy peel film or the like can be adopted. The sealant layer 162 may be configured as a single layer or a multilayer with a film made of these materials.

[0039] In addition, when heat resistance is required for the packaging container 1, the sealant layer 162 preferably has a cast polypropylene layer (CPP layer) mainly composed of cast polypropylene (CPP), or a linear low-density polyethylene layer (LLDPE layer) mainly composed of low-density polyethylene (LDPE) or linear low-density polyethylene (LLDPE).

[0040] The thickness of the sealant layer 162 is preferably 20 μm or more, more preferably 30 μm or more. Also, the thickness of the sealant layer 162 is preferably 200 μm or less, more preferably 160 μm or less. If the thickness of the sealant layer 162 is less than 20 μm, it is not desirable because the impact resistance against drops and the like that may occur during the distribution process of the packaging container 1 cannot be ensured sufficiently. Also, if the thickness of the sealant layer 162 is greater than 200 μm, it is not desirable because the thickness of the sealant layer becomes too thick more than necessary.

[0041] Other layers can be provided to complement various functions according to the application, and their arrangement positions can be selected as appropriate. In order to be able to store the contents for a long time, other layers may have a vapor barrier property that prevents the permeation of water vapor and a gas barrier property that prevents the permeation of gases such as oxygen gas. Also, other layers may have a function of sufficiently enhancing the concealment so that the contents of the packaging container 1 are not visible in order to increase the consumer's willingness to purchase. Therefore, examples of other layers include a gas barrier layer, a light-shielding layer, etc. in addition to the above-described pattern layer.

[0042] Examples of the gas barrier layer include a metal foil such as an aluminum foil and a vapor deposition layer. The vapor deposition layer may be provided on the base material layer or on the sealant layer. The vapor deposition layer may be a metal vapor deposition layer composed of a vapor deposition layer of a metal such as aluminum, or a transparent vapor deposition layer composed of a vapor deposition layer of an inorganic oxide such as aluminum oxide or silicon oxide.

[0043] Also, the gas barrier layer may include a vapor deposition layer and an organic coating layer formed on the vapor deposition layer. The organic coating layer is formed by applying a barrier coating agent onto a vapor deposition film and solidifying it. The barrier coating agent is composed of a metal alkoxide, a hydroxyl group-containing water-soluble resin, a silane coupling agent added as required, a sol-gel method catalyst, an acid, and the like.

[0044] As the metal alkoxide, the general formula is R1 n M(OR 2 ) m (However, in the formula, R 1 , R 2 represents an organic group having 1 to 8 carbon atoms, M represents a metal atom, n represents an integer of 0 or more, m represents an integer of 1 or more, and n + m represents the valence of M.) At least one or more metal alkoxides represented by, as the metal atom represented by M of the metal alkoxide, silicon, zirconium, titanium, aluminum, and others can be exemplified. For example, it is preferable to use an alkoxysilane in which M is Si.

[0045] As the above alkoxysilane, for example, the general formula Si(ORa) 4 (However, in the formula, Ra represents a lower alkyl group.) is represented by. In the above, as Ra, a methyl group, an ethyl group, an n-propyl group, an n-butyl group, and others are used. Specific examples of the above alkoxysilane include, for example, tetramethoxysilane Si(OCH 3 ) 4 , tetraethoxysilane Si(OC 2 H 5 ) 4 , tetrapropoxysilane Si(OC 3 H 7 )4, tetrabutoxysilane Si(OC 4 H 9 ) 4 , and others can be used. The above alkoxides may be used in combination of two or more.

[0046] As the silane coupling agent, those having reactive groups such as vinyl group, epoxy group, methacryl group, amino group, etc. can be used. In particular, organoalkoxysilane having an epoxy group is preferable. For example, γ-glycidoxypropyltrimethoxysilane, γ-glycidoxypropylmethyldimethoxysilane, γ-glycidoxypropyldimethylmethoxysilane, γ-glycidoxypropyltriethoxysilane, γ-glycidoxypropylmethyldiethoxysilane, γ-glycidoxypropyldimethylethoxysilane, or β-(3,4-epoxycyclohexyl)ethyltrimethoxysilane, etc. can be used. The above-mentioned silane coupling agent may be used by mixing one kind or two or more kinds.

[0047] Among them, the crosslinking density of the cured film of the organic coating layer using bifunctional agents such as γ-glycidoxypropylmethyldimethoxysilane and γ-glycidoxypropylmethyldiethoxysilane is lower than the crosslinking density in the system using trialkoxysilane. Therefore, while being excellent as a film having gas barrier properties and heat-resistant water treatment properties, it becomes a flexible cured film and is also excellent in flex resistance. Therefore, the packaging material using the barrier film is less likely to deteriorate in gas barrier properties even after the gelbo flex test.

[0048] The hydroxyl group-containing water-soluble resin can be used alone with a polyvinyl alcohol-based resin or an ethylene-vinyl alcohol copolymer, or can be used in combination of a polyvinyl alcohol-based resin and an ethylene-vinyl alcohol copolymer.

[0049] As the light-shielding layer, a metal foil such as aluminum or a metal vapor deposition layer can be exemplified. In addition, for other layers, two or more of the above-mentioned functional layers may be laminated.

[0050] As shown in FIG. 5(A), the first laminated film 160 of the present embodiment is laminated with a base material layer 161, a gas barrier layer 163 (other layer), a pattern layer 164 (other layer), a bonding layer 165, a base material layer 161, a bonding layer 165, and a sealant layer 162 in this order from the outside of the container. As this bonding layer 165, for example, an adhesive generally used by a known dry lamination method can be used. For example, a polyvinyl acetate-based adhesive, a polyacrylate-based adhesive, a cyanoacrylate-based adhesive, an ethylene copolymer-based adhesive, a cellulose-based adhesive, a polyester-based adhesive, a polyamide-based adhesive, an amino resin-based adhesive, an epoxy-based adhesive, a polyurethane-based adhesive, etc. can be used.

[0051] Alternatively, an adhesive resin layer generally used in an extrusion lamination method (sandwich lamination method) can be used as the bonding layer 165. As the thermoplastic resin that can be used for the adhesive resin layer, a polyethylene-based resin, a polypropylene-based resin, a cyclic polyolefin-based resin, a copolymer resin, a modified resin, or a mixture (including an alloy) mainly composed of these resins can be used. As the polyolefin-based resin, for example, low-density polyethylene (LDPE), medium-density polyethylene (MDPE), high-density polyethylene (HDPE), linear (linear) low-density polyethylene (LLDPE), polypropylene (PP), an ethylene-α-olefin copolymer polymerized using a metallocene catalyst, a random or block copolymer of ethylene and polypropylene, an ethylene-vinyl acetate copolymer (EVA), an ethylene-acrylic acid copolymer (EAA), an ethylene-ethyl acrylate copolymer (EEA), an ethylene-methacrylic acid copolymer (EMAA), an ethylene-methyl methacrylate copolymer (EMMA), an ethylene-maleic acid copolymer, an ionomer resin, and, in order to improve the adhesion between layers, the above-mentioned polyolefin-based resin modified with an unsaturated carboxylic acid such as acrylic acid, methacrylic acid, maleic acid, maleic anhydride, fumaric acid, itaconic acid, etc., such as an acid-modified polyolefin-based resin, can be used. Also, a resin obtained by graft polymerization or copolymerization of an unsaturated carboxylic acid, an unsaturated carboxylic acid anhydride, or an ester monomer onto a polyolefin resin can be used. These materials can be used alone or in combination of two or more. As the cyclic polyolefin-based resin, for example, cyclic polyolefins such as an ethylene-propylene copolymer, polymethylpentene, polybutene, polynorbornene, etc. can be used. These resins can be used alone or in combination of a plurality. In this case, there may be an anchor coat layer (AC layer) between the substrate layer, and for example, an adhesive generally used in a known dry lamination method can be used. For example, polyvinyl acetate adhesives, polyacrylate adhesives, cyanoacrylate adhesives, ethylene copolymer adhesives, cellulose adhesives, polyester adhesives, polyamide adhesives, amino resin adhesives, epoxy adhesives, polyurethane adhesives, etc. can be used.

[0052] As a preferred embodiment of the first laminated film 160, the following layer structures can be exemplified in order from the outside of the container. (A) Substrate layer / Sealant layer (B) First substrate layer / Second substrate layer / Sealant layer (C) First substrate layer / Second substrate layer / Third substrate layer / Sealant layer (D) First substrate layer / Second substrate layer / Third substrate layer / Fourth substrate layer / Sealant layer

(1) PET film thickness 12 μm / Inorganic oxide vapor deposition layer / Organic coating layer / Pattern layer / PET film thickness 12 μm / PE film thickness 50 μm (2) PET film thickness 12 μm / Inorganic oxide vapor deposition layer / Organic coating layer / Pattern layer / Biaxially stretched polyamide film thickness 15 μm / PE film thickness 50 μm (3) PET film thickness 12 μm / Inorganic oxide vapor deposition layer / Organic coating layer / Pattern layer / PE film thickness 60 μm (4) PET film thickness 12 μm / Pattern layer / PET film thickness 12 μm / Aluminum vapor deposition layer / PE film thickness 50 μm (5) PET film thickness 12 μm / Pattern layer / PET film thickness 12 μm / Aluminum vapor deposition layer / CPP film thickness 50 μm (6) Biaxially stretched polypropylene (OPP) film thickness 20 μm / Pattern layer / PET film thickness 12 μm / Aluminum vapor deposition layer / PE film thickness 50 μm (7) 2 - axis stretched polypropylene (OPP) film with a thickness of 20 μm / pattern layer / PET film with a thickness of 12 μm / aluminum vapor deposition layer / CPP film with a thickness of 50 μm (8) PET film with a thickness of 12 μm / pattern layer / aluminum foil with a thickness of 7 μm / 2 - axis stretched polyamide (ONY) film with a thickness of 15 μm / PE film with a thickness of 50 μm (9) PET film with a thickness of 12 μm / pattern layer / aluminum foil with a thickness of 7 μm / PE film with a thickness of 50 μm (10) PET film with a thickness of 12 μm / pattern layer / PE film with a thickness of 15 μm / PET film with a thickness of 12 μm / aluminum vapor deposition layer / PE film with a thickness of 15 μm / CPP film with a thickness of 50 μm (11) 2 - axis stretched polypropylene (OPP) film with a thickness of 20 μm / pattern layer / PE film with a thickness of 15 μm / PET film with a thickness of 12 μm / aluminum vapor deposition layer / PE film with a thickness of 15 μm / CPP film with a thickness of 50 μm (12) PET film with a thickness of 12 μm / pattern layer / PE film with a thickness of 15 μm / aluminum foil with a thickness of 7 μm / PE film with a thickness of 15 μm / PE film with a thickness of 50 μm (13) 2 - axis stretched polypropylene (OPP) film with a thickness of 20 μm / pattern layer / CPP film with a thickness of 60 μm

[0054] At least one of the laminated films constituting the front - surface film 11 and the back - surface film 12 preferably has a total light transmittance of 40% or more, more preferably 50% or more. Thereby, when moving a part of the content from the accommodating part 10 to the measuring part 20, the inside of the packaging container 1 can be visually confirmed, and the measurement of the content can be performed more reliably. Note that the total light transmittance of the film can be measured based on the JIS standard (JIS K 7361 - 1:1997), and for example, it can be measured using a haze meter (model number: HM - 150) manufactured by Murakami Color Technology Co., Ltd. with the following specifications. Parallelism of light beam: less than 3° Diameter of light beam: Φ14 mm (entrance aperture: Φ20 mm) Reading accuracy: ±0.1% Diameter of the integrating sphere: Φ150 mm Filter: D65 light

[0055] (Second laminated film) As shown in FIG. 5(B), for example, the second laminated film 170 of the present embodiment is laminated with a base material layer 171, an adhesive layer 175, and a sealant layer 172 in this order from the side opposite to the side joined to the front film 11 and the back film 12. The base material layer 171, the sealant layer 172, and the adhesive layer 175 can be made of the same materials as the base material layer 161, the sealant layer 162, and the adhesive layer 165 of the first laminated film 160 described above, respectively.

[0056] As a preferred embodiment of the laminated film 170, the following layer configurations can be exemplified in order from the side opposite to the side joined to the front film 11 and the back film 12. (A) Base material layer / Sealant layer (B) First base material layer / Second base material layer / Sealant layer

[0057] As a specific example of the laminated film 170, the following layer configurations can be exemplified in order from the side opposite to the side joined to the front film 11 and the back film 12. (1) PET film thickness 12 μm / PE film thickness 50 μm (2) PET film thickness 12 μm / CPP film thickness 50 μm (3) Biaxially oriented polyamide (ONY) film thickness 15 μm / PE film thickness 50 μm (4) Biaxially oriented polyamide (ONY) film thickness 15 μm / CPP film thickness 50 μm (5) PET film thickness 12 μm / Biaxially oriented polyamide (ONY) film thickness 15 μm / PE film thickness 50 μm (6) PET film thickness 12 μm / Biaxially oriented polyamide (ONY) film thickness 15 μm / CPP film thickness 50 μm

[0058] Next, the appearance of the packaging container 1 will be described. FIG. 6 is a diagram for explaining the appearance of the packaging container 1. As described above, the packaging container 1 has a display portion 50 on the surface of the surface film 11. It is desirable that this display portion 50 be provided so as to avoid overlapping the metering portion 20 from the viewpoint of visually recognizing the movement of the contents to the metering portion 20. In the packaging container 1 of the present embodiment, as shown in FIG. 6, the display portion 50 is provided at a position corresponding to the accommodating portion 10 on the surface of the surface film 11. The display portion 50 is a portion where the usage method of the packaging container 1 is described. In the present embodiment, it is formed as a pattern layer 164 by printing on the inner side of the container of the base material layer 161. Note that the display portion 50 is not limited to printing, and may be in any form as long as it is visible from the appearance of the packaging container 1. For example, it may be in the form of a label attached to the surface of the surface film 11.

[0059] As shown in FIG. 6, the following displays, for example, are made on the display portion 50 as the usage method. "Please close the chuck portion of the packaging container." "Turn the packaging container upside down and move a part of the contents in the accommodating portion to the metering portion." "After the movement to the metering portion is completed, return the packaging container to its original posture." "Open the chuck portion, grasp the grasping instruction portion, and extract the contents that have moved to the metering portion." Note that this display is an example, and its content can be changed as appropriate. Also, an explanation of the contents, specifications, expiration date, etc. may be added.

[0060] Further, it is desirable that the packaging container 1 be provided with a grasping instruction portion 51 on at least one of the surface film 11 and the back film 12. This grasping instruction portion 51 indicates the portion of the packaging container 1 to be grasped in order to more easily extract the contents moved to the metering portion 20 in an appropriate amount from the chuck portion 40. By grasping this grasping instruction portion 51 and performing the operation, the user can more easily take out the contents measured in a predetermined amount in the metering portion 20 outside the container. The gripping instruction part 51 is provided at least at a position overlapping the hole part 32 of the partition part 30 on at least one surface of the front film 11 and the back film 12. In the present embodiment, as shown in FIG. 6, the gripping instruction part 51 is provided at positions overlapping the hole part 32 provided at the left end part of the packaging container 1 and at the right end part on the side opposite to the hole part. In the present embodiment, the gripping instruction part 51 is formed as a pattern layer 164 by printing on the inner side of the container of the base material layer 161, but it is not limited to printing, and any form may be used as long as it is visible from the appearance of the packaging container 1. For example, it may be in the form of a label attached to the surface of the front film 11. Note that the above-described display part 50 and gripping instruction part 51 may be omitted as necessary.

[0061] (Usage method of the packaging container) Next, the usage method of the packaging container 1 will be described. FIG. 7 is a diagram for explaining the usage method of the packaging container 1 of the present embodiment. First, the user separates the upper seal part 101 from the container main body part 2 by the notch 7. Next, after confirming that the chuck part 40 is closed, the user turns the packaging container 1 upside down (a posture in which the chuck part 40 faces vertically downward). As a result, the folded partition part 30 opens slightly due to the weight of the content N, and accordingly, the opening area of the hole part 32 also expands, and a part of the content N accommodated in the accommodation part 10 moves through the hole part 32 to the metering part 20 as shown in FIG. 7(A). The content N almost accumulates in the metering part 20 up to the position of the fold part 31 where the hole part 32 is formed. Next, as shown in FIG. 7(B), the user returns the packaging container 1 to the original posture (a posture in which the chuck part 40 faces vertically upward). As a result, most of the content N1 that has moved to the metering part 20 moves into the gap between the partition part 30 formed in a gusset shape and the front film 11 and the back film 12 without returning to the accommodation part 10. At this time, the partition part 30 returns to the folded state again.

[0062] Here, as shown in FIG. 1, in the case where the partition portion 30 of the packaging container 1 of the present embodiment is in a folded state, the distance between the fold line portion 31 provided on the partition portion 30 and the lower end edge of the chuck portion 40 is defined as H1, and the distance between the lower end edge of the measuring portion 20 (the edge on the housing portion 10 side) and the fold line portion 31 is defined as H2, the packaging container 1 is formed so as to satisfy H2 > H1. Thereby, when the packaging container 1 is turned upside down and the content N1 is moved to the region of the distance H1 in the measuring portion 20 and then the packaging container 1 is returned to its original posture, the content N1 will move to the region of the distance H2 in the measuring portion 20. However, as described above, since the relationship of H2 > H1 holds, it is possible to extremely suppress the content N1 that has moved to the measuring portion 20 from returning to the housing portion 10 side.

[0063] Next, the user opens the chuck portion 40 of the packaging container 1, and as shown in FIG. 7(C), grasps the gripping instruction portion 51 provided on the packaging container 1 with a finger, tilts the opening of the packaging container 1 downward, and takes out the content N1 that has moved to the measuring portion 20 outside the container. At this time, since the user is grasping the gripping instruction portion 51, the hole portion 32 provided in the partition portion 30 is in a substantially closed state, and it is possible to significantly suppress the content N remaining in the housing portion 10 from being taken out together with the measured content N1 even when the packaging container 1 is tilted.

[0064] Also, if the user tries to take out the content N1 that has moved to the measuring portion 20 without grasping the gripping instruction portion 51, although the gusset of the partition portion 30 will also open slightly by opening the chuck portion 40, since the hole portion 32 is provided in the vicinity of the side seal portion 103, the amount of opening at the position where the hole portion 32 is provided is smaller compared to the central portion of the partition portion 30. Therefore, it is possible to sufficiently suppress the content N remaining in the housing portion 10 from being taken out together with the measured content N1 through the hole portion 32.

[0065] From the above, the packaging container 1 of the present embodiment has a simple structure and can take out a predetermined amount of content by a simple operation. In addition, when the distance between the lower edge of the measuring unit 20 (the edge on the housing unit 10 side) and the lower edge of the housing unit 10 is H3 in the state where the partition unit 30 is folded, the area where the housing unit 10 houses the content is H2 + H3. Here, from the viewpoint of enabling the content housed in the housing unit 10 to be measured and taken out by the measuring unit 20 a plurality of times, it is desirable that H2 + H3 > H1.

[0066] (Other forms of the packaging container) The packaging container 1 of the present embodiment is not limited to the form shown in FIG. 1 and the like described above, and various modifications are possible. FIGS. 8 to 15 are diagrams showing other forms of the packaging container 1 of the first embodiment.

[0067] (Other form 1 of the first embodiment) As shown in FIG. 8, the packaging container 1 of the present embodiment may be provided with two hole portions 32 in the partition portion 30. More specifically, it may be provided at the left end portion (the end portion on the third edge side) and the right end portion (the end portion on the fourth edge side) of the partition portion 30. Thereby, the content housed in the housing unit 10 can be moved to the measuring unit 20 more easily and efficiently.

[0068] (Other form 2 of the first embodiment) As shown in FIG. 9, the packaging container 1 of the present embodiment may be such that in the width direction, the chuck portion 40 is provided closer to the right end of the measuring unit 20, and the hole portion 32 of the partition portion 30 is provided closer to the left end of the partition portion 30. In this case, when the packaging container 1 is viewed from the upper side, it is more desirable that the position of the hole portion 32 of the partition portion 30 and the position of the chuck portion 40 do not overlap. By adopting such a configuration, when taking out the content moved to the measuring unit 20 from the chuck portion 40, it is possible to more effectively suppress the content housed in the housing unit 10 from leaking out through the hole portion 32.

[0069] (Other form 3 of the first embodiment) As shown in Fig. 10, the packaging container 1 of this embodiment may be provided with a gusset-shaped bottom portion 60 at the lower part. More specifically, the container body portion 2 of this form includes a bottom film 14 in addition to the front film 11, the back film 12, and the partition film 13. The bottom film 14 folded in two may be sandwiched between the lower parts of the front film 11 and the back film 12 with the fold line 61 positioned on the upper side and joined. Thereby, the packaging container 1 can be made self-standing, and the usability of the packaging container 1 can be further improved. In addition, as shown in Fig. 11, in the packaging container 1 of this form, before the contents are accommodated, a side seal planned portion 103' is formed in a part of the side portion 4 of the accommodation portion 10, which is an unsealed portion. After the contents are accommodated in the accommodation portion 10, a side seal portion 103 is formed in the side seal planned portion 103' by heat sealing. Moreover, either the above-described first laminated film 160 or the second laminated film 170 can be used for the bottom film 14.

[0070] (Another form 4 of the first embodiment) As shown in Fig. 12, the packaging container 1 of this embodiment may be provided with a through hole 8 in the upper seal portion 101. Thereby, when the packaging container 1 containing the contents is displayed as a product at a storefront or the like, the packaging container 1 can be hung on a hook or the like of a display stand through the through hole 8 for display.

[0071] (Another form 5 of the first embodiment) As shown in Fig. 13, the packaging container 1 of this embodiment may form the partition seal portion 104 of the gusset-shaped partition portion 30 in a concave shape. More specifically, the shapes of the partition seal portions 104 of the first half and the second half of the partition film 13 folded in two may be concave shapes with arc-shaped cutouts, and the adhesive area may be made narrower from one end to the central portion in the left-right direction (width direction) and wider again from the central portion to the other end. Thereby, the packaging container 1 of this form can more easily take out the contents that have moved to the metering portion 20 of the packaging container 1.

[0072] (Another form 6 of the first embodiment) As shown in FIG. 14, instead of providing the chuck portion 40 as the opening / closing portion, the packaging container 1 of this embodiment may be provided with a spout portion 70 including a pouring outlet 71 and a lid portion 72 that can open and close the opening of the pouring outlet 71. In this case, the notch 7 for separating the upper seal portion 101 can be omitted from the side seal portion 103. As a result, the packaging container 1 of this embodiment can accommodate not only powdery substances and granular substances but also liquid substances as contents, and in particular, the liquid contents can be easily taken out of the container without spilling.

[0073] (Another form 7 of the first embodiment) As shown in FIG. 15, the packaging container 1 of this embodiment may be configured such that the spout portion 70 described in the above-mentioned another form 6 is disposed at one end (left end) in the left-right direction of the packaging container 1, and the hole portion 32 provided in the partition portion 30 is disposed at the other end (right end). In this case, when the packaging container 1 is viewed from the upper side, it is more desirable that the position of the hole portion 32 of the partition portion 30 and the position of the spout portion 70 do not overlap. By adopting such a configuration, in addition to the effects of the above-mentioned another form 6, when the contents moved to the measuring portion 20 are taken out from the spout portion 70, it is possible to more effectively suppress the leakage of the contents accommodated in the accommodating portion 10 from the hole portion 32.

[0074] (Evaluation of content measurement) Next, the evaluation of the measurement of the contents by the measuring portion 20 of the packaging container 1 of this embodiment was performed. The contents are composed of a plurality of granular bodies, and the maximum dimension of one granular body is 0.5 mm or more and 2.5 mm or less. Here, the maximum dimension of one granular body refers to the dimension of the portion having the largest dimension among the outer shapes of the granular bodies. The measurement of the maximum dimension of one granular body was performed using a microscope (manufactured by KEYENCE CORPORATION, VHX-6000). The lens of the microscope was VH-ZST, and the observation magnification was 20 times. The packaging container 1 used in this evaluation is in the form of the above-described other form 1 (see Fig. 8). The hole portions 32 provided in the partition portion 30 are provided in a circular shape at the left end portion and the right end portion, and the diameter of each hole portion 32 is 10 mm. The accommodating portion 10 accommodated 112 g of the above-described granular material. Based on the usage method shown in Fig. 7 above, a part of the content accommodated in the accommodating portion 10 was moved to the measuring portion 20, the content measured by the measuring portion 20 was taken out from the chuck portion 40, and the weight of the taken-out content was measured. In this evaluation, this operation was performed 5 times, and the measurement results were as follows. First time: 5.3 g Second time: 5.8 g Third time: 5.6 g Fourth time: 5.8 g Fifth time: 5.0 g From the above measurement results, it was confirmed that the weight of the content measured by the packaging container 1 of this embodiment is within an error range of within 0.5 g with respect to the average value (5.5 g) of 5 times, and has a sufficient measuring function.

[0075] (Second Embodiment) Next, the packaging container 1B of the second embodiment will be described. Fig. 16 is a plan view of the packaging container 1B of the second embodiment. Fig. 17 is a side view and a partial cross-sectional view of the packaging container 1B of Fig. 16. Fig. 17(A) is a side view of the packaging container 1B, and Fig. 17(B) is a partial cross-sectional view of the packaging container 1B cut at the position of arrow B-B in Fig. 16. Fig. 18 is an exploded perspective view for explaining the composition of the packaging container 1B of the second embodiment. The packaging container 1B of this embodiment is different from the packaging container 1 of the above-described first embodiment in that the configuration of the partition portion 30B is different. Therefore, parts that perform the same functions as those in the first embodiment are denoted by the same reference numerals or the same reference numerals at the end, and duplicate explanations are appropriately omitted.

[0076] As shown in FIGS. 16 to 18, the partition portion 30B is formed by a partition film 13B folded in two, and is joined to the front film 11 and the back film 12 such that the fold portion 31B is positioned on the upper side (first edge side). More specifically, for the partition film 13B folded in two, the peripheral portion of the first half excluding the fold portion 31B is joined to the front film 11 by heat sealing, and the peripheral portion of the second half excluding the fold portion 31B is joined to the back film 12 by heat sealing. By these joints, a partition seal portion 104B is formed between the peripheral portion of the first half excluding the fold portion 31B of the partition film 13B and the front film 11, and between the peripheral portion of the second half excluding the fold portion 31 of the partition film 13 and the back film 12. As a result, a gusset-shaped partition portion 30B is disposed between the front film 11 and the back film 12, and a storage portion 10 is formed in the lower part of the container body portion 2 with the partition portion 30B as a boundary, and a metering portion 20 is formed in the upper part of the container body portion 2.

[0077] Here, in the left-right direction of the container body portion 2, the width of the partition film 13B is equal to the width of the container body portion 2. Therefore, the partition portion 30B is arranged with its side edge aligned with the side edge of the container body portion 2. As shown in the side view of FIG. 17(A) and FIG. 18, the side edges of the first half and the second half of the partition film 13B folded in two are joined to the front film 11 and the back film 12, respectively, and the side edges of the inner surface of the first half and the side edges of the inner surface of the second half of the partition film 13B folded in two are joined. As a result, a partition seal portion 104B is formed between the front film 11 and the first half of the partition film 13B, between the inner surfaces of the partition film 13B folded in two, and between the second half of the partition film 13B and the back film 12 at the side portion of the partition portion 30B. In the region where the storage part 10 and the metering part 20 of the container main body 2 are formed, as shown in FIG. 17(B), in the partition film 13B, only the lower end edges of the first half and the second half are joined to the surface film 11 and the back film 12 by the partition seal part 104B respectively, and the inner surfaces of the partition film 13B folded in two are not joined.

[0078] The surface film 11 and the back film 12 of the present embodiment are constituted by the first laminated film 160 in the same manner as in the above-described first embodiment. On the other hand, the partition film 13B of the present embodiment is constituted by a third laminated film 180 different from the first embodiment.

[0079] (Third laminated film) Next, the third laminated film used for the partition part 30B of the packaging container 1B will be described. FIG. 19 is an example of a cross-sectional view of the third laminated film used for the partition part 30B of the packaging container 1B of the present embodiment. The partition film 13B is made of the third laminated film 180. As described above, in the partition part 30B, the outer surface and the inner surface of the partition film 13B folded in two are heat-sealed at the side edges respectively. Therefore, the third laminated film 180 is provided with at least a base material layer 181, a first sealant layer 182 having sealability on one surface of the base material layer 181, and a second sealant layer 183 having sealability on the other surface of the base material layer 181. The third laminated film 180 may include a plurality of the above base material layers, or each sealant layer may be composed of a plurality of layers.

[0080] As shown in FIG. 19, the third laminated film 180 of the present embodiment is laminated, for example, with a first sealant layer 182, an adhesive layer 185, a base material layer 181, an adhesive layer 185, and a second sealant layer 183 in this order from the side joined to the front film 11 and the back film 12. As the base material layer 181, the first sealant layer 182, the second sealant layer 183, and the adhesive layer 185, the same materials as the base material layer 161, the sealant layer 162, and the adhesive layer 165 of the first laminated film 160 described in the above-described first embodiment can be used respectively.

[0081] As a preferred embodiment of the laminated film 180, the following layer configurations can be exemplified in order from the side joined to the front film 11 and the back film 12. (A) First sealant layer / Base material layer / Second sealant layer

[0082] As a specific example of the laminated film 180, the following layer configurations can be exemplified in order from the side joined to the front film 11 and the back film 12. (1) PE film thickness 30 μm / Biaxially stretched polyamide (ONY) film thickness 15 μm / PE film thickness 50 μm (2) CPP film thickness 30 μm / Biaxially stretched polyamide (ONY) film thickness 15 μm / CPP film thickness 50 μm (3) HS agent thickness 3 μm / Biaxially stretched polyamide (ONY) film thickness 15 μm / PE film thickness 50 μm (4) HS agent thickness 3 μm / Biaxially stretched polyamide (ONY) film thickness 15 μm / CPP film thickness 50 μm

[0083] Here, the sealant layer formed by the above HS agent is formed by applying and drying a heat-sealing agent (HS agent) obtained by dissolving or dispersing a heat-sealing resin in an organic solvent or an aqueous solvent containing water on one surface of a PET film. Examples of the heat-sealing resin include polyolefin resins such as EVA (ethylene-vinyl acetate copolymer) and ionomer resins, modified polyolefin resins such as vinyl chloride-vinyl acetate copolymer and chlorinated polyolefin, polyester resins, acrylic resins, polyethyleneimine resins, etc., and each single substance or copolymer can be used. From the above, the packaging container 1B of the present embodiment has a simple structure and can take out a predetermined amount of contents by simple operations. Note that the packaging container 1B of the present embodiment is provided with the display unit 50 and the gripping instruction unit 51 in the same manner as in the above-described first embodiment, but the display unit 50 and the gripping instruction unit 51 may be omitted as necessary.

[0084] (Other forms of the packaging container) The packaging container 1B of the present embodiment is not limited to the form shown in FIG. 16 and the like described above, and various modifications are possible. FIGS. 20 and 21 are views showing other forms of the packaging container 1B of the second embodiment.

[0085] (Other form 1 of the second embodiment) As shown in FIG. 20, the packaging container 1B of the present embodiment may be provided with two hole portions 32B in the partition portion 30B. More specifically, it may be provided at the left end portion (the end portion on the third edge side) and the right end portion (the end portion on the fourth edge side) of the partition portion 30B. Thereby, the contents accommodated in the accommodation portion 10 can be moved to the measuring portion 20 more easily and efficiently.

[0086] (Other form 2 of the first embodiment) As shown in Fig. 21, in the packaging container 1B of this embodiment, in the width direction, the chuck portion 40 may be provided closer to the right end portion of the metering portion 20, and the hole portion 32B of the partition portion 30B may be provided closer to the left end portion of the partition portion 30B. In this case, when the packaging container 1B is viewed from the upper side, it is more desirable that the position of the hole portion 32B of the partition portion 30B and the position of the chuck portion 40 do not overlap. By adopting such a configuration, when taking out the content moved to the metering portion 20 from the chuck portion 40, it is possible to more effectively suppress the content accommodated in the accommodating portion 10 from leaking out through the hole portion 32B.

[0087] (Modification) Without being limited to the embodiments described above, various modifications and changes are possible, and they are also within the scope of the present invention.

[0088] (1) In the embodiment, an example in which the front surface film 11 and the back surface film 12 are individual laminated films 160 is shown, but the present invention is not limited thereto, and they may be configured from a single connected laminated film 160.

[0089] (2) In the second embodiment, the packaging container 1B may be provided with a gusset-shaped bottom as in another form 3 (Fig. 10) of the packaging container 1 of the first embodiment described above. Further, the packaging container 1B may be configured such that, as in another form 5 (Fig. 13) of the packaging container 1 of the first embodiment described above, the shapes of the front half and the rear half of the partition seal portions 104B of the two-folded partition film 13B are concave shapes with arc-shaped cutouts, and the adhesive area becomes narrower from one end portion to the central portion in the left-right direction (width direction), and becomes wider again from the central portion to the other end portion. Furthermore, the packaging container 1B may be provided with a spout portion composed of a pouring port and a lid portion for opening and closing the opening of the pouring port instead of providing the chuck portion 40 as the opening / closing portion, as in another form 6 (Fig. 14) of the packaging container 1 of the first embodiment described above.

[0090] (3) In the embodiment, an example where the front film 11 and the back film 12 are formed transparently has been shown, but the present invention is not limited thereto, and they may be formed opaquely by a pattern layer, a light-shielding layer, or the like. Even in this case, from the viewpoint of checking the remaining amount of the content in the storage portion 10 or checking the content measured by the measuring portion 20, a transparent portion (transparent window) through which the inside can be seen may be provided in at least a part of one of the front film 11 and the back film 12.
