  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 to 7 are diagrams showing an embodiment of the present invention.

  First, the outline of the package used in the package management method and the package management system according to the present embodiment will be described with reference to FIG.

  A packaging body 10 shown in FIG. 1 includes a packaging bag 11 and contents 12 stored in the packaging bag 11. Among these, the packaging bag 11 is produced from the packaging material 20 mentioned later, and the heat seal parts 13, 14, and 15 are provided in the upper end part, the lower end part, and the back part, respectively. A barcode 27 and an identification code 28, which will be described later, are displayed on the surface of the packaging bag 11 so as to be visible from the outside. On the other hand, examples of the content 12 include foods such as health foods, but the configuration of the content 12 is not limited thereto.

  Next, the configuration of the packaging material 20 constituting the packaging bag 11 will be described with reference to FIG.

  As shown in FIG. 2, the packaging material 20 includes a heat seal layer 21 and a gas barrier layer 22 provided on the heat seal layer 21. A base ink layer 23 is provided on the gas barrier layer 22, and a printing ink layer 24 is provided on the base ink layer 23. Further, a cover layer 25 is provided on the printing ink layer 24.

  The heat-seal layer 21 is used to join materials together when the packaging material 20 is joined to form a bag. By providing the heat-seal layer, the bag is sealed easily. it can. For example, when the packaging bag 11 is produced using the packaging material 20, the heat sealing layer 21 of one packaging material 20 and the heat sealing layer 21 of the other packaging material 20 are joined to each other to heat the above-described heat. Seal portions 13, 14, and 15 are formed. As a heat sealing method, for example, a bar seal, a rotary roll seal, a belt seal, an impulse seal, a high frequency seal, an ultrasonic seal or the like can be used.

  As the heat seal layer 21, a conventionally known thermoplastic resin can be used. For example, low density polyethylene (LDPE), linear (linear) low density polyethylene (polymer polymerized using a multi-site catalyst). , LLDPE), ethylene-α / olefin copolymer polymerized using metallocene catalyst (single site catalyst), medium density polyethylene (MDPE), high density polyethylene (HDPE), polypropylene resin, ethylene-vinyl acetate copolymer, Ionomer resin, ethylene-acrylic acid copolymer, ethylene-ethyl acrylate copolymer, ethylene-methacrylic acid copolymer, ethylene-methyl methacrylate copolymer, ethylene-propylene copolymer, methylpentene polymer, polybutene polymer One or more types of resin such as It can be used Ranaru resin.

  The heat seal layer 21 preferably has a film thickness of 1 to 100 μm, and the film thickness is preferably about 15 to 40 μm from the viewpoint of layer stability and cost during heat sealing.

  The gas barrier layer 22 is for shielding the contents filled in the packaging bag made of the packaging material from oxygen or the like, and can be formed using a conventionally known gas barrier material. Examples of gas barrier materials include saponified ethylene-vinyl acetate copolymers (hereinafter abbreviated as EVOH) and MXD6 (polymetaxylylene adipamide), and PET blended with gas barrier resins such as MXD6. Those obtained by depositing an inorganic oxide such as silica or alumina or amorphous carbon on a substrate such as PET can be suitably used. As a method other than using a vapor deposition means, a coating means may be used, for example, a thermosetting crosslinked coating film of an aromatic polyvalent epoxy compound obtained by reacting metaxylenediamine and epichlorohydrin and a polyvalent amine, By coating EVOH or the like, the gas barrier property can be improved. When EVOH is coated, gas barrier properties are reduced due to moisture absorption, and therefore, it is preferable to coat a moisture-proof resin such as a polyolefin resin thereon. Any one kind of such gas barrier property improving means may be used, but by using a combination of two or more means, the gas barrier property can be further improved.

  The gas barrier layer 22 preferably has a film thickness of about 6 to 50 μm from the viewpoint of gas barrier performance and cost.

  The base ink layer 23 constitutes a base layer that is visually recognized from the outside through the transparent cover layer 25 after the packaging bag 11 is formed, and improves the visibility of the printing ink layer 24 described later. In addition, the base layer of the packaging bag 11 is configured. In order to improve the visibility of printing such as a barcode, the base ink layer is preferably white, but depending on the design of the packaging bag 11, the base ink layer 23 is composed of an ink layer of a color other than white. May be. For example, the base ink layer 23 can be formed by a normal printing method such as offset printing, gravure printing, flexographic printing, letterpress printing, silk screen printing, or the like using a normal ink composition.

  On the other hand, the printing ink layer 24 includes a color ink layer 26 formed on the base ink layer 23 and a barcode 27 formed on the base ink layer 23 and formed by an ink jet printer.

  Among these, the color ink layer 26 indicates, for example, characters or patterns related to the contents 12 displayed on the surface of the packaging bag 11. On the other hand, the barcode 27 includes identification information (for example, a manufacturing number, a lot number, a manufacturing location, etc. of each package 10) set individually for each package 10. An identification code 28 printed by an ink jet printer is formed on the base ink layer 23. The identification code 28 corresponds to the identification information included in the barcode 27, and is composed of characters or symbols that can be directly identified by a person, such as a number representing a manufacturing number.

  The cover layer 25 is a layer that protects the barcode 27 and the like of the printing ink layer 24, but it is also necessary that the printed image can be clearly seen. For these reasons, it is preferable to use a transparent or translucent thermoplastic resin for the surface layer, and it is more preferable to use a transparent thermoplastic resin. Examples of the transparent thermoplastic resin include polyolefin resins such as polyethylene and polypropylene, polystyrene, polyvinyl chloride, polyvinylidene chloride, polyvinyl alcohol, ethylene / vinyl alcohol copolymer, polyacrylonitrile, polyamide, acrylic ester, and methacrylate. Acrylic resins mainly composed of acid esters, polyethylene terephthalate, polybutylene terephthalate, polyesters such as polyethylene naphthalate, polyacetal, acetyl di- or tricellulose fiber derivatives, and thermoplastic resins such as polycarbonate, A biaxially stretched film of polyester or nylon 6 can be preferably used.

  The cover layer 25 preferably has a thickness of about 6 to 50 μm from the viewpoint of protection performance and cost.

  Next, the barcode 27 of the printing ink layer 24 will be described with reference to FIGS.

  As shown in FIG. 3A, the barcode 27 of the printing ink layer 24 is formed between a plurality of thick bars 71, a plurality of thin bars 72, and each thick bar 71 and each thin bar 72. It is composed of a combination with other spaces (thick space 73 and narrow space 74). In FIG. 3A, only a part of this combination is shown.

  The fine bar 72 is composed of a plurality of round ink units 75 each printed by an ink jet printer and arranged in at least one row (one row in FIG. 3A). On the other hand, the thick bars 71 are each printed by an ink jet printer and are composed of a plurality of round ink units 75 arranged in multiple rows (three rows in FIG. 3A) from the rows of thin bars 72.

As shown in FIG. 3A, the center-to-center distance between the round ink units 75 adjacent in the width direction (X direction) is A, and the round ink adjacent in the height direction (Y direction). The center-to-center distance between the units 75 is B. In FIG. 3A, the widths of the thick bar 71, the thin bar 72, the thick space 73, and the fine space 74 are w ₁ , w ₂ , w ₃ , and w ₄ , respectively. In general, in such a barcode 27, the ratio of the widths of the thick bar 71, the thin bar 72, the thick space 73, and the thin space 74 is w ₁ : w ₂ : w ₃ : w ₄ = 2.5: 1: 2.5: 1 is recommended (hereinafter also referred to as the recommended ratio).

  On the other hand, as shown in FIG. 3B, when the diameter of the round ink unit 75 is d, the overlap L (= d−A) between adjacent rows of the round ink unit 75 is the round ink unit. The diameter d of 75 is preferably 0.09 to 0.11 (that is, 0.09d ≦ L ≦ 0.11d).

When the overlap L is less than 0.09d (that is, when L <0.09d), the width ratio w ₁ : w ₂ between the thick bar 71 and the thin bar 72 deviates from the recommended ratio. It is not preferable. On the other hand, when the overlap L exceeds 0.11d (that is, when 0.11d <L), the narrow space 74 becomes too narrow, and the width ratio w ₂ : w ₄ between the narrow bar 72 and the narrow space 74 is This is not preferable because it deviates from the recommended ratio.

  Also in the barcode length direction (Y direction), the round ink units 76 may overlap with adjacent round ink units between rows. As shown in FIG. 3C, the round ink unit 76 constituting the fine bar and the thick bar has an overlap M (= d−B) between adjacent rows of the round ink unit 76 when the diameter is d. ) Is preferably 0.15 to 0.35 times the diameter d of the round ink unit 76 (that is, 0.15d ≦ M ≦ 0.35d). In both thin and thick bars, Y-direction round ink units overlap with adjacent round ink units between rows, improving barcode visibility and preventing barcode reading errors. it can.

  The predetermined barcode described above can be formed by printing using an ink jet printer. Hereinafter, a method of printing the barcode 27 using an ink jet printer will be described with reference to FIG.

  In FIG. 4, the cover layer 25 continuously moves at a constant speed in the width direction (X direction) (see arrow P).

  On the other hand, charged ink particles 62 are periodically ejected from the ejection head 61 of the inkjet printer. The position of the ink particles 62 ejected in this manner is changed in the height direction (Y direction) by changing the charge amount by the electric field from the pair of electrode plates 63.

  Thereafter, the ink particles 62 reach the cover layer 25 that is continuously moving. At this time, each ink particle 62 adheres on the cover layer 25 as a round ink unit 75. By gathering the plurality of round ink units 75, the barcode 27 is printed on the cover layer 25.

  The center-to-center distance A between the round ink units 75 adjacent in the width direction (X direction) is controlled by, for example, the period at which the ink particles 62 are ejected from the ejection head 61 of the inkjet printer, or the moving speed of the cover layer 25. Is possible. The center-to-center distance B between the round ink units 75 adjacent in the height direction (Y direction) is the amount of charge due to the electric field from the electrode plate 63, the voltage applied to the electrode plate 63, or the electrode plate 63 and the cover layer 25. It is possible to control by the distance D between and the like.

  FIG. 5 is a diagram showing another configuration of the packaging material. In the packaging material 20 shown in FIG. 5, a first base material layer 29 made of, for example, polyethylene (PE) is provided on the first base material layer 29 between the heat seal layer 21 and the gas barrier layer 22. The first anchor coat layer 30 is interposed. As shown in FIG. 2, the heat seal layer 21 and the gas barrier layer 22 are formed by a conventional method, for example, a wet lamination method, a dry lamination method, an extrusion lamination method, a coextrusion coating lamination method, a T-die. Lamination can be performed by an extrusion molding method, a T-die co-extrusion molding method, or the like. As the anchor coat layer, the surface of the base material layer is previously subjected to corona treatment, ozone treatment, or the like, or isocyanate-based (urethane-based), polyethyleneimine-based, polybutadiene-based, organic titanium on the base material layer. By applying anchor coating agent such as laminating adhesive such as anchor coating agent such as polyurethane, polyurethane, polyacrylic, polyester, polyvinyl acetate, epoxy, cellulose, etc. An anchor coat layer can be formed.

  Similarly, a second base material layer 31 made of, for example, polyethylene (PE) and a second anchor provided on the second base material layer 31 are also provided between the gas barrier layer 22 and the base ink layer 23. A coat layer 32 is interposed.

  In FIG. 5, the heat seal layer 21, the gas barrier layer 22, the base ink layer 23, the printing ink layer 24, and the cover layer 25 are the same as those of the packaging material 20 shown in FIG. Detailed description is omitted.

  Next, the operation of the present embodiment having such a configuration will be described with reference to FIGS.

  First, the manufacturing method of the packaging material 20 will be described with reference to FIGS. Hereinafter, the case of the packaging material 20 having the configuration shown in FIG. 5 will be described as an example. 6A to 6H, for convenience, the packaging material 20 is illustrated upside down with respect to FIG.

  First, a cover layer 25 made of a transparent thermoplastic resin such as transparent polyethylene terephthalate (PET) is prepared (FIG. 6A). Here, as the cover layer 25, for example, Toyobo Co., Ltd., T-4100, 12 μm thick PET film can be used.

  Next, the barcode 27 and the identification code 28 are printed at predetermined positions on the cover layer 25 using an ink jet printer, and then dried for a predetermined time (FIG. 6B).

  After printing the bar code 27 and the identification code 28 on the cover layer 25 in this way, a color ink layer 26 is further formed on the cover layer 25 by gravure printing, and this is dried for a predetermined time. The color ink layer 26 may be composed of one color, but is preferably composed of a plurality of colors. When the color ink layer 26 is composed of a plurality of colors, gravure printing is performed for each color and drying is performed. In this way, the printing ink layer 24 including the color ink layer 26, the barcode 27, and the identification code 28 is formed on the cover layer 25 (FIG. 6C).

  Next, a base ink layer 23 made of, for example, white ink is formed on the printing ink layer 24 by gravure printing and dried (FIG. 6D).

  Next, a second anchor coat layer 32 is formed on the base ink layer 23 and dried (FIG. 6E). As the second anchor coat layer 32, for example, AC-Q manufactured by The Inktec Co., Ltd. can be used.

  Subsequently, on the second anchor coat layer 32, polyethylene (PE) (second base material layer 31) dissolved at a high temperature using an extrusion laminator is extruded, and the second base material layer 31 is Then, a gas barrier layer 22 made of aluminum or the like is laminated (FIG. 6F). In addition, as polyethylene which comprises the 2nd base material layer 31, the Japan polyethylene company make and LC-600A can be used, for example. Moreover, as the gas barrier layer 22, for example, Toyo Aluminum Co., Ltd., IN30 type, 7 μm thick aluminum thin can be used.

  Next, the first anchor coat layer 30 is formed on the gas barrier layer 22 and dried (FIG. 6G). As the first anchor coat layer 30, for example, AC-Q manufactured by The Inktec Co., Ltd. can be used.

  Further, polyethylene (PE) (first base material layer 29) dissolved at a high temperature is extruded onto the first anchor coat layer 30 using an extrusion laminating machine, and the first base material layer 29 is Then, a heat seal layer 21 made of LLDPE or the like is laminated. In this way, the packaging material 20 is produced (FIG. 6 (h)). In addition, as polyethylene which comprises the 1st base material layer 29, the Japan polyethylene company make and LC-600A can be used, for example. Moreover, as the heat seal layer 21, for example, DNP Techno Film, SRX, foamed polyethylene having a thickness of 40 μm can be used.

  The package according to this embodiment described above makes it difficult to forge the barcode of the printing ink layer. In addition, since the package includes such a barcode, the authenticity of the package and the distribution route can be reliably determined. A package management system capable of more reliably performing authenticity determination and reliable determination of distribution routes will be described.

  FIG. 7 shows a package management method and a package management system according to an embodiment of the present invention. First, as described above, the packaging material 20 is produced (FIGS. 6A to 6H), and the packaging material 20 is wound to produce the roll 40.

  Next, the packaging material 20 is unwound from the roll 40 and cut with a predetermined width. Subsequently, the cut packaging material 20 is folded into a bag shape, and the back surface and the lower end portion thereof are heat-sealed (heat seal portions 14 and 15), thereby producing the packaging bag 11. Next, the contents 12 are accommodated inside the packaging bag 11, and the upper end portion of the packaging bag 11 is heat-sealed (heat sealing portion 13). In this manner, the package 10 including the packaging bag 11 and the contents 12 stored in the packaging bag 11 is produced. At this time, a bar code 27 and an identification code 28 are displayed at easy-to-see positions on the surface of the packaging bag 11.

  Next, the barcode 27 provided on each package 10 is read by the first reader 41. The identification information of each package 10 read by the first reader 41 is transmitted to the management unit 42 made of, for example, a computer and registered in the management unit 42.

  Thus, when registering the identification information of each package 10 in the management unit 42, the management information for each package 10 corresponding to this identification information is registered in the management unit 42 together with the identification information of each package 10. It is preferable to keep it.

  Here, the management information for each package 10 refers to information required when specifying each package 10 on the market after shipping each package 10. Preferably, the management information includes, for example, information related to the shipping destination of each package 10. In addition, the management information may include the type of contents 12 of each package 10 or the date of manufacture of each package 10.

  If the first reader 41 does not correctly read the barcode 27 on the surface of the packaging bag 11, the identification information of each package 10 is manually managed by referring to the value of the identification code 28. 42 may be input.

  After registering the identification information of each package 10 in the management unit 42, the plurality of packages 10 are collected and accommodated in the outer box 43. Thereafter, the plurality of packaging bodies 10 are shipped together with the outer box 43, and each packaging body 10 is conveyed to the user by means such as mail order.

  By the way, after each package 10 is shipped, it is illegally sold by a distributor (for example, the package 10 is sold with the expiration date of the content 12 expired, or the content 12 in the packaging bag 11 is replaced and sold. May be performed). In addition, a problem may occur in the contents 12 in the process of distributing each package 10. In this case, the packaging body 10 in question is collected from the packaging bodies 10 on the market, and the barcode 27 of the packaging body 10 is read by the second reader 44.

  Thus, the identification information of each package 10 read by the second reader 44 is transmitted to the management unit 42 described above. Next, the management information of each package 10 (for example, the shipping destination of each package 10 and the like) is specified by collating the identification information of each package 10 by the management unit 42. In the present embodiment, the second reader 44 is a reader different from the first reader 41. However, the present invention is not limited to this, and the first reader 41 and the second reader 44 are the same reader. May be.

  Specifically, for example, when it is considered that someone is illegally selling the package 10, the barcode 27 of the package 10 in question is read and the package 10 registered in the management unit 42 is read. Check with the management information. Thereby, the distributor of the said package 10 is specified, and a countermeasure can be taken.

  The first reader 41, the management unit 42, and the second reader 44 described above constitute a package management system 50 according to the present embodiment.

  As described above, according to the present embodiment, the packaging bag 11 of the package 10 includes a heat seal layer 21, a gas barrier layer 22, a base ink layer 23, and a bar code 27 formed by an inkjet printer. The packaging material 20 includes an ink layer 24 and a cover layer 25. With such a configuration, unlike the case where the barcode 27 is printed directly on the surface of the cover layer 25, the barcode 27 cannot be wiped off and cannot be tampered with. Therefore, it is difficult to forge the barcode 27.

  Further, according to the present embodiment, the barcode 27 is not printed on the surface of the cover layer 25 as described above. Therefore, if the barcode 27 of the package 10 distributed in the market is printed on the surface of the cover layer 25, it can be considered that the package 10 is a counterfeit product. It can be judged accurately.

  Further, according to the present embodiment, the barcode 27 of each package 10 on the market is read by the second reader 44, and the read identification information of each package 10 is sent to the management unit 42. The management unit 42 specifies the distribution route of each package 10 based on the identification information of each package 10 registered in advance. Thereby, the distribution route of package 10 can be specified certainly.

  In the present embodiment, the use of the barcode 27 attached to each package 10 is not limited to the above-described one, and for example, the following may be considered. That is, the seller of the package 10 performs lottery based on the number of the barcode 27 and announces the number of the selected barcode 27. Next, the selected user of the package 10 sends an empty packaging bag 11 to the seller of the package 10. On the other hand, the seller confirms that the numerical value of the barcode 27 of the sent packaging bag 11 is authentic by the second reader 44 and then sends the product to the selected user. You can also consider the use of.
