Description

  The present invention relates to an integrated packaging film and an integrated packaging body.

  In an integrated package that collectively packages a plurality of articles, an integrated product barcode (hereinafter referred to as an “integrated barcode”) provided in the background printing region is provided on the packaging film. Each article is also provided with an individual barcode, but when sold as a collection, the collection barcode is read by a barcode reader. At this time, since the individual barcode may be erroneously read (misidentified), several integrated packaging films provided with a shielding portion for shielding the individual barcode have been proposed (for example, Patent Document 1, Patent Document 1). 2).

JP 2001-39468 A Registration Model No. 3008968

  However, as the sensitivity of the barcode reader has increased, it has become impossible to sufficiently prevent the individual barcode from being misidentified with the film disclosed in the above-mentioned patent document. Specifically, when an individual barcode is located below (behind) the background print area, the barcode reader is increasingly reading the individual barcode through the background print area. Yes. On the other hand, as shown in FIG. 11, a film 100 in which a plurality of oblique shielding bars 102 for shielding individual barcodes 23 are provided outside the integrated barcode display unit 101 has been proposed. Misidentification of the individual barcode 23 located below (behind) cannot be prevented sufficiently.

  An integrated packaging film according to the present invention includes a film base material and an integrated barcode display unit formed on the film base material, and the integrated bar film is used for packaging a plurality of articles together. The code display unit includes a background printing region, an integrated barcode formed in the background printing region, and a first formed at least between the integrated barcode in the background printing region and an end of the region. And a shielding part.

  With the increase in sensitivity of the barcode reader, etc., even individual barcodes covered with the integrated barcode display unit may be read, but according to the above configuration, the reading is prevented by the first shielding unit. be able to. That is, according to the said structure, the misidentification of the separate barcode which was not able to respond with the conventional film can fully be prevented.

In the integrated packaging film according to the present invention, it is preferable that at least a part of the first shielding portion is formed of a substantially linear first shielding bar. More preferably, the first shielding bar is formed from one end portion to the other end portion of the background print region.
According to the said structure, the misidentification of an individual barcode can be prevented more highly.

Further, it is preferable that the first shielding portion is formed in a direction substantially perpendicular to the plurality of bars constituting the integrated barcode.
When the integrated barcodes overlap on the individual barcodes, the readability of the integrated barcodes is better when the bars of both barcodes are substantially perpendicular than when the bars of both barcodes are substantially parallel to each other. According to the above configuration, when the bars of both barcodes are substantially perpendicular to each other, for example, the first shielding bar is overlapped so as to be substantially parallel to the bar of the individual barcode. To be prevented. In other words, the bar code defines information by the thickness and gap of the bar. In this case, since the first shielding bar shields a part of the bar or the gap in the individual barcode over the entire area, Reading is effectively prevented.

The first shielding part may be formed continuously with the second shielding part formed outside the background printing area.
According to the said structure, reading of the separate barcode which is not covered by the integrated barcode display part is prevented by the 2nd shielding part. And by forming the 1st shielding part and the 2nd shielding part continuously, for example, the printing of a shielding part is simplified and the appearance of the film for accumulation packaging becomes good.

  An integrated package according to the present invention is an integrated package including a plurality of articles each having an individual barcode, wherein the integrated packaging film includes at least the first shielding part and the second shielding part. The article is packaged in a state in which any one is positioned on the individual barcode.

  In the integrated packaging body according to the present invention, it is preferable that in the integrated packaging film, the first shielding portion is formed substantially parallel to a plurality of bars constituting the individual barcode.

  ADVANTAGE OF THE INVENTION According to this invention, even if it is a case where a highly sensitive barcode reader is used, the integrated package which can fully prevent the misidentification of an individual barcode can be provided.

Hereinafter, an example of an embodiment of the present invention will be described in detail with reference to the drawings.
The drawings referred to in the embodiments are schematically described, and the dimensions and the like of the components drawn in the drawings may be different from the actual products. Specific dimensions and the like should be determined in consideration of the following description.

  In this specification, descriptions such as substantially linear, substantially vertical, substantially identical, substantially parallel, etc. are states that can be regarded as substantially linear, substantially vertical, substantially identical, and substantially parallel. Means. For example, “substantially perpendicular” means a state in which the angle formed between the target A and the target B is about 90 ° ± 10 ° (the target A and the target B may not intersect each other).

  In the description of the embodiment, as an article constituting the integrated package, an article 20 that is a bottle container filled with a beverage or the like, and an article 60 that is a metal container (canned food or the like) filled with food or the like are exemplified. The article is not limited to this, and may be, for example, a plastic bottle, a paper box, a dry battery, or the like. In the description of the embodiment, terms indicating directions (based on normal usage) such as “up and down” and “left and right” are used, but the relationship between each component and the direction is not limited.

<First Embodiment>
With reference to FIGS. 1 to 8, the integrated packaging body 10 and the integrated packaging film 30 constituting the integrated packaging body 10 according to the first embodiment of the present invention will be described in detail.

FIG. 1 is a perspective view of the stacked packaging body 10 as viewed obliquely from above (print layer 39 etc. omitted).
The integrated packaging body 10 includes a plurality of articles 20 and an integrated packaging film 30 that packages the articles 20 together. The integrated packaging body 10 has a packaging form in which an integrated packaging film 30 wraps the entire plurality of articles 20 and the plurality of articles 20 are arranged in a line (in the first embodiment, the direction along the line of the articles 20 is defined). Sometimes referred to as “left-right direction”). In the example shown in FIG. 1, four articles 20 are integrated and packaged, but the number of articles 20 is not particularly limited. Also, there may be a plurality of rows of articles 20.

  The article 20 is a bottle container having a barrel portion 21 filled with a beverage or the like and a cap portion 22 attached to the barrel portion 21. The body part 21 is provided with an individual barcode 23. The individual bar code 23 includes a plurality of linear bars 24 arranged in parallel with each other in one direction. For example, the individual bar code 23 may have a product number of the article 20 depending on the thickness of the bars 24 and the interval between the bars 24. Provides information such as prices. That is, the individual barcode 23 is configured by a plurality of bars 24 and gaps between the bars 24. In the example shown in FIG. 1, a plurality of bars 24 are arranged in the vertical direction of the article 20.

  The integrated packaging film 30 wraps an integrated product in which a plurality of articles 20 are arranged in a line, and the edges are joined together to seal the integrated product. The integrated packaging film 30 preferably has heat shrinkability, and is attached to follow the shape of each article 20 by heat shrinking to bind the articles 20 together.

FIG. 2 shows an integrated packaging film 30 (before heat shrinkage) constituting the integrated packaging body 10.
The integrated packaging film 30 includes a film base material and an integrated barcode display unit 31 formed on the film base material. The integrated barcode display unit 31 is preferably formed by a printing method such as gravure printing using a desired ink. On the film substrate, in addition to the integrated bar code display unit 31, a print layer 39 for displaying a trade name, raw materials, precautions for use, various designs, and the like can be formed. In addition, a pressure-sensitive adhesive layer, an anchor coat layer, a protective layer for the print layer 39, and the like may be formed on the film substrate.

  In addition, it is preferable that the integrated packaging body 10 is manufactured using a elongate film from a viewpoint of productivity (refer FIG. 4 mentioned later). Although FIG. 2 shows a state of being cut into individual film sizes, the integrated packaging film 30 is preferably in the form of an elongated body before being attached to the article 20.

  The film substrate is preferably composed of a heat-shrinkable film. Examples of the heat-shrinkable film include heat of polyester resin (polyethylene terephthalate, polylactic acid, etc.), polyolefin resin (polyethylene, polypropylene, etc.), polystyrene resin (styrene-butadiene copolymer, etc.), polyvinyl chloride, etc. Examples thereof include a film made of a plastic resin, a film made of a mixture of a plurality of resins, and a laminated film in which a plurality of films are laminated (including different kinds of laminated films). The heat-shrinkable film is, for example, uniaxially stretched or biaxially stretched, and the heat shrinkage rate in the main stretching direction is preferably 20 to 90% (immersed in warm water at 90 ° C. for 10 seconds).

  The integrated barcode display unit 31 includes a background printing region 32, an integrated barcode 33 formed in the background printing region 32, and a shielding unit 35 that shields the individual barcode 23 of the article 20. The integrated barcode display unit 31 is preferably located on the individual barcodes 23 of all the articles 20, and the integrated packaging film 30 wraps the articles 20 in such a positional relationship. Further, when a plurality of articles 20 are stacked, it is preferable to arrange the individual barcodes 23 so as to face the same direction. In the example shown in FIG. 1, the background printing region 32 covers one or two individual barcodes 23, and the shielding portion 35 is located on all the individual barcodes 23 including the remaining individual barcodes 23. Yes.

  The background print area 32 has a function of making it easy to specify the position of the integrated barcode 33, for example. The background print region 32 can be provided by forming a solid print layer on the film substrate. The solid print layer can be formed in a different color from the integrated barcode 33, but is generally a light-colored print layer formed in white, yellow, light blue, or the like. The background print region 32 can be formed in a rectangular shape in plan view, but the formation pattern is not limited to this. In the background printing area 32, a product name or the like (for example, OOXX 50ml x 4 packs) is printed.

  Similar to the individual barcode 23, the integrated barcode 33 includes a plurality of linear bars 34 arranged in parallel with each other in one direction, and has information such as the product number and price of the integrated product. Such information is defined by, for example, the thickness of the bars 34, the interval between the bars 34, and the like. In the example shown in FIG. 1, a plurality of bars 34 are arranged in the direction (left-right direction) along the row of the articles 20. That is, the bar 34 extends in the vertical direction and is substantially perpendicular to the bar 24 of the individual barcode 23. The integrated bar code 33 is also given a number that defines the above information.

  The shielding portion 35 includes a shielding bar 36 that is a first shielding portion formed between the integrated barcode 33 in the background printing region 32 and the end of the region, and a second portion formed outside the background printing region 32. And a shielding bar 37 which is a shielding part. The shielding bars 36 and 37 are substantially straight bars extending in the left-right direction. The shielding bars 36 and 37 are substantially linear over the entire length, but may be partially non-linear.

  The shielding bar 36 is formed from the left end portion which is one end portion of the background printing region 32 to the right end portion which is the other end portion. The shielding bar 37 extends from the left end portion and the right end portion of the background print area 32, respectively. Specifically, the shielding bar 37 extends from both ends of the shielding bar 36, and the shielding bars 36, 37 are formed on substantially the same straight line. In other words, the shielding unit 35 has a single shielding bar that protrudes from the left and right ends across the background printing region 32, or a shielding bar that is formed outside the background printing region 32 extends into the background printing region 32. It can be said that. In any case, it is provided continuously.

  From the standpoint of improving the shielding function, the thickness of the shielding bars 36 and 37 is preferably thicker than the bar 24 of the individual barcode 23, particularly when the number of bars is small. The thickness of the shielding bars 36 and 37 is set to be at least twice that of the thickest bar 24, for example. The shielding bars 36 and 37 need to be formed in a color recognized by the barcode reader. For example, dark print colors such as black, dark gray, dark blue, dark blue, brown, and dark green are used. It is said. By making the background print region 32 light-colored and the shielding bars 36 and 37 dark, the contrast between the two becomes large and the shielding bars 36 and 37 are easily recognized by the barcode reader.

  The shielding bar 36 is formed between the integrated barcode 33 and the upper end portion of the background print region 32, specifically, between the integrated barcode 33 and the print portion. The shielding bar 36 is formed in a direction substantially perpendicular to the plurality of bars 34 constituting the integrated barcode 33.

FIG. 3 shows an enlarged view of the vicinity of the integrated barcode display unit 31 in the integrated package 10.
As described above, the integrated packaging film 30 wraps the article 20 in a state where the shielding portion 35 is positioned on the individual barcode 23. A part of one or two individual barcodes 23 among the plurality of articles 20 is covered with a background print region 32. A shielding bar 36 is formed in a portion of the background print area 32 that covers the individual barcode 23. That is, the shielding bar 36 is located on the individual barcode 23. A shielding bar 37 is positioned on the remaining portion of the individual barcode 23 that is not covered by the background print region 32.

  In the integrated package 10, the bar 34 of the integrated barcode 33 and the bar 24 of the individual barcode 23 are substantially perpendicular to each other. As a result, when the integrated barcode 33 is read, the integrated barcode 33 is less affected by the individual barcode 23 and the readability of the integrated barcode 33 is improved. Since the shielding bar 36 is formed in a direction substantially perpendicular to the bar 34, the shielding bar 36 and the shielding bar 37 that is substantially collinear with the bar 34 are arranged on the individual barcode 23. And almost parallel. All the individual barcodes 23 are shielded by the shielding bars 36 and 37 over the entire length in the direction in which the bar 24 extends.

With reference to FIG. 4, an example of a manufacturing method of the integrated packaging body 10 having the above configuration will be described.
In the manufacturing process of the integrated packaging body 10, first, the long bodies 30 z of the integrated packaging film 30 are placed on the plurality of articles 20 that are continuously conveyed in a line. Specifically, the long body 30z is sent out in accordance with the conveyance speed of the article 20, covered from above the article 20, and wrapped downward to form a cylindrical shape that wraps the whole of the plurality of articles 20. At this time, the seal part 40 along the longitudinal direction of the long body 30z is formed in a part that wraps around the article 20 below. Thereby, it will be in the state where the some articles | goods 20 were inserted in the cylinder of the elongate body 30z.

  The positional relationship between the article 20 and the integrated packaging film 30 is adjusted so that the shielding bars 36 and 37 are positioned on the individual barcodes 23 of the plurality of articles 20 inserted into the cylinder of the long body 30z.

  Subsequently, the cylinder of the long body 30z into which the plurality of articles 20 are inserted is cut and divided into individual package sizes. At this time, it is preferable to form the seal portion 41 simultaneously with the cutting. Thereby, while the cylinder of the elongate body 30z is cut into the size of each packaging body, the axial direction edge part is closed. In addition, the number of the articles | goods 20 contained in the stacking package 10 can be changed by changing a cut position suitably. Finally, the integrated packaging film 30 is heat-shrinked while maintaining the positional relationship, and the integrated packaging body 10 in which the articles 20 are bound is manufactured. The heat shrink treatment can be performed using, for example, a steam type or hot air type shrink tunnel.

  As described above, according to the integrated packaging body 10, the individual barcode 23 can be shielded by the shielding part 35 including the shielding bars 36 and 37. Thereby, the misidentification of the individual barcode 23 located under (behind) the background printing region 32 can be sufficiently prevented. As the sensitivity of the barcode reader increases, the individual barcode 23 covered with the background printing region 32 may be read by the conventional label. However, the integrated package 10 performs the reading by the function of the shielding bar 36. To prevent.

  Further, the integrated bar code 33 and the bar 24 of the individual bar code 23 are made substantially perpendicular to each other, and the shielding bars 36 and 37 are made substantially parallel to the bar 24 on the individual bar code 23, whereby the integrated bar code 33 Good readability and good shielding of the individual barcode 23 can be achieved at the same time.

  5 to 8 show integrated barcode display units 31v to 31y which are modifications of the integrated barcode display unit 31. FIG. Here, the same components as those in the integrated barcode display unit 31 are denoted by the same reference numerals, and redundant description thereof is omitted. Differences from the integrated barcode display unit 31 will be mainly described.

The integrated barcode display unit 31v shown in FIG. 5 includes a plurality of substantially parallel shielding bars 36v extending from the left and right ends of the background printing region 32 into the region, and a plurality of substantially parallel bars extending outside the region. The shielding bar 37v is formed. The shielding bar 36v is formed only within a predetermined length range from the left and right ends of the background print region 32. A shielding character 38 that functions as the shielding portion 35 is formed between the left and right shielding bars 36v. For example, the product name or the like can be printed as the shielding character 38.
In the example shown in FIG. 5, a form without the shielding character 38 or a form in which the left and right shielding bars 36v are connected instead of the shielding character 38 may be used.

In the integrated barcode display unit 31w shown in FIG. 6, the shielding bar 36w and the shielding bar 37w do not exist on substantially the same straight line, and the shielding bar 37w is positioned below the shielding bar 36w. The shielding bar 37w is connected to the center in the vertical direction of both the left and right ends of the background printing region 32, and the integrated barcode 33 is present on the extended line of the shielding bar 37w. Therefore, the shielding bar 36w is formed above the shielding bar 37w, avoiding the integrated barcode 33.
In the example shown in FIG. 6, a shielding bar that crosses the integrated barcode 33 in the left-right direction may be formed within a range that does not impair the readability of the integrated barcode 33.

  A large number of shielding bars 36x and 37x are formed in the integrated barcode display portion 31x shown in FIG. The shielding bar 36x is formed over substantially the entire area of the background print region 32 except for the portion where the integrated barcode 33 is formed, and a shielding bar 37x is formed on the extended line of the shielding bar 36x. Moreover, the thickness of the shielding bars 36x and 37x can be made thinner than the thickest bar 24 of the individual barcode 23, for example. Since the shielding bars 36x and 37x are large in number, the individual barcode 23 can be sufficiently shielded even if the thickness thereof is equal to or less than the bar 24.

  In the integrated barcode display portion 31y shown in FIG. 8, the background print area 32y extends in the left-right direction, and a shield (shield bar 36y) is formed only in the background print area 32y. For example, the background printing area 32y is arranged so as to cover individual barcodes of a plurality of articles. In this case, a plurality of individual barcodes can be shielded by the shielding bar 36y.

  In the above description, the shielding portion 35 is configured by the shielding bars 36 and 37 or the shielding characters 38. However, the shielding portion may have other forms. The shielding part may be configured by, for example, dots such as ●, ▲, and ■, chain lines, and various patterns.

Second Embodiment
With reference to FIGS. 9 and 10, the integrated packaging body 50 according to the second embodiment of the present invention and the integrated packaging film 70 constituting the integrated packaging body 50 will be described in detail. Here, differences from the first embodiment will be described, and redundant description will be omitted.

FIG. 9 is a perspective view of the stacking package 50 as viewed obliquely from above.
In the integrated package 50, articles 60 that are a plurality of (for example, five) metal containers are stacked in the vertical direction to form an integrated product, and the entire integrated product is packaged with an integrated packaging film 70. The article 60 has a cylindrical shape, and the integrated package 50 also has a cylindrical shape. The individual barcodes 63 of the articles 60 face the same direction, and a plurality of bars 64 constituting the individual barcodes 63 extend in the vertical direction.

  The integrated packaging film 70 wraps the article 60 so that the integrated barcode display unit 71 is positioned on the plurality of individual barcodes 63. Specifically, the background print area 72 is arranged so as to cover the individual barcode 63, and includes a shielding bar 76 formed in the background print area 72 and a shielding bar 77 formed outside the background print area 72. The individual barcode 63 is shielded by the shield 75. The shielding bars 76 and 77 extend in the vertical direction and are substantially parallel to the bar 64 of the individual barcode 63. Thereby, the misidentification of the individual barcode 63 can be prevented to a high degree. Note that the bar 74 of the bar code 73 also extends in the vertical direction. That is, the shielding bars 76 and 77 are substantially parallel to the bar 74.

FIG. 10 is a view showing an integrated package 50v which is a modification of the integrated package 50. As shown in FIG.
The integrated package 50v has an integrated barcode display unit 71v similar to the integrated barcode display unit 31 shown in FIG. 1 instead of the integrated barcode display unit 71 of the integrated package 50. The shielding bars 76v and 77v extend in a direction substantially perpendicular to the bar 74v of the barcode 73v. The integrated packaging film 70v is attached to the integrated product so that the bar 74v extends in the circumferential direction of the cylinder and the shielding bars 76v and 77v are substantially parallel to the bar 64 of the individual barcode 63. Since the bar 74v of the bar code 73v and the bar 64 of the individual bar code 63 are substantially perpendicular to each other, the readability of the bar code 73v is improved.
