Description

  The present invention relates to a package in which a plurality of identical articles are stacked and integrally packaged by a transparent film.

  In some cases, a plurality of individually salable items, for example, two cartons of tissue cartons may be integrally packaged and sold. In this case, it is necessary to print an identification code in which the product information is recorded on the packaging portion, or to separately attach an identification code label. On the other hand, an identification code such as a bar code recording the product information is already printed on each tissue carton. Therefore, in a carton pack in which a plurality of tissue cartons are integrally packaged, it is necessary to ensure that the identification code printed on each tissue carton is not read.

  Therefore, as described in, for example, Patent Document 1, a barcode printed in advance on a transparent shrink film, or a barcode printed on a same product with a barcode label attached to the surface of a shrink package It is arranged to overlap with the This makes it possible to hide the barcode printed on each item from the outside by the barcode printed on the shrink film and the barcode label attached to the surface of the shrink package.

JP, 2016-193747, A

  In a package in which a plurality of identical articles are stacked in the same direction and these are integrally wrapped by a transparent film, it is visually clarified that this package is a collection of a plurality of individual products. It is desirable to In a tissue carton, an identification code including information on the tissue carton is usually printed on the bottom of the carton box. When such tissue cartons are stacked in the same direction and shrink-wrapped, it is possible to obtain a high visual effect by displaying information indicating that the tissue cartons are not individually packaged on the laterally long side portions of the tissue cartons. Then, from a design point of view, it is considered to form the area straddling the bottom and the side of the carton box as an integral colored part on the shrink film.

  As is well known, a shrink package covers a plurality of identical articles superimposed on one another with shrink film, heatseals the opening and heat shrinks the entire film to produce a plurality of identical articles superimposed on one another. It will be in close contact with it. For this reason, in the case of a shrink package on which an identification code or the like is previously printed, there is a possibility that the portions printed on the shrink film, which should be disposed on the bottom and the laterally long side of the tissue carton, may deviate. In particular, if the thermal contraction identification code does not exactly overlap the identification code printed on the tissue carton, mechanical reading of the identification code on the packaging line becomes difficult. The same applies to the case where a label printed with an identification code is mechanically attached to a transparent film.

  It is an object of the present invention to visually check at the time of inspection whether or not the position of the colored part is located in the intended area of the package when the colored part is disposed on a transparent film which integrally packages a plurality of identical articles. Or to provide a package that can be easily identified by optical inspection.

  A package according to the present invention is a package formed by integrally packaging a plurality of identical articles each having a first surface and a second surface adjacent to the first surface via a weir with a transparent film. A body, wherein a part of the film has a first coloring portion facing the first surface of at least one of the articles, the first surface and the second surface being exposed to the outside; A position between the first and second colored portions and a second colored portion facing the second surface of the at least one article in which the first and second surfaces are exposed to the outside And continue to the two colored portions, and face the first surface and the second surface exposed to the outside of the at least one article and the ridge between them, for the at least one article Identify the degree of positional deviation of the first and second colored portions Characterized in that the positional deviation identifying portion for are arranged.

  In the present invention, it is determined that the position of the colored portion of the film with respect to the article is incorrect when the misregistration identification portion disposed on the film does not overlap the crease of the article. In other words, the degree of positional deviation of the first or second colored portion in the direction orthogonal to the crease between the first surface and the second surface of the article is determined.

  In the package according to the present invention, a first identification code containing information on the article is printed on the first side of the article, and the first colored portion has a second identification code containing information on the package, Preferably, the second identification code is arranged to cover the first identification code on the first side of the article. Note that the term "identification code" used in this specification is a well-known optically readable one-dimensional code indicating various information related to various articles, that is, a bar code, or a QR code (manufactured by DENSO WAVE INC. It means a two-dimensional code such as a registered trademark).

  The second coloring portion may include a character, and the term "character" as used in this specification is meant to include characters and symbols and figures and patterns and / or a combination thereof.

  The first and second coloring parts and the misregistration identification part may be a label attached to the film. Alternatively, the first and second colored portions and the misregistration identification portion may be pre-printed on the shrink film before packaging, and the heat bonding portion and the heat shrinkable portion of the shrink film are the first and second parts of the article. It is preferable to be in a position facing the surface other than the second surface.

  The length along the heel of the misplacement identification portion facing the heel may be longer as the distance from the heel is greater along the direction orthogonal to the heel. Conversely, the length along the heel of the misplacement identification portion facing the heel may be shorter as the distance from the heel is longer along the direction orthogonal to the heel. Alternatively, the misalignment identification unit facing the eyebrow may be offset in any direction along the eyelid with respect to the first coloring portion and the second coloring portion.

  According to the package of the present invention, since the misalignment identification unit for identifying the degree of misalignment of these articles with respect to the article is disposed between the first coloring unit and the second coloring unit, Misalignment of the first and second coloring portions with respect to the article can be easily identified.

  If the first colored portion has a second identification code, and the second identification code is arranged to cover the first identification code printed on the first side of the article, the outer side of the package From the first identification code can be made invisible.

  When the second colored portion includes a character, it can be clearly indicated that the package is a package in which a plurality of identical articles are packaged.

  In the case of the label in which the first and second colored portions and the misregistration identification portion are attached to the film, the label can be attached after packaging. In addition, the first and second colored portions and the misregistration identifying portion are positions where the heat bonding portion and the heat shrinking portion of the shrink film printed before packaging are opposed to the surfaces other than the first and second surfaces of the article. When set to, it is possible to minimize the positional deviation of the colored part after shrink packaging.

  When the length along the ridge of the misplacement identification portion facing the ridge is longer along the direction perpendicular to the ridge and away from the ridge, the first and second colored portions of the first and second colored portions are referred to The degree of relative position deviation can be easily identified. The same applies to the case where the length along the heel of the misplacement identification unit facing the heel is shorter as the distance from the heel is longer along the direction orthogonal to the heel. In addition, even when the misregistration identification unit facing the eyelid is offset in any direction along the eyelid with respect to the first coloring area and the second coloring area, the first eye and the second eye can be determined with reference to the eyelid of the article. It is possible to easily identify the degree of deviation of the relative position of the second colored portion.

It is the perspective view which looked at the appearance of one embodiment which applied the package by a present invention to two sets of tissue cartons by which shrink packaging was carried out from the bottom side. It is a disassembled perspective view of embodiment shown in FIG. 1, and a shrink film extracts and shows only the printed coloring part and misregistration identification part. It is the front view which extracted and expanded the coloring part and positional offset identification part of shrink film in embodiment shown in FIG. It is a front view showing the other form of a coloring part and a position shift recognition part. It is a front view showing another form of a coloring part and a position shift recognition part.

  An embodiment in which the package according to the present invention is applied to a shrink-packed two-piece tissue carton will be described in detail with reference to FIGS. 1 to 5, but the present invention is limited to only such an embodiment. It is also possible to further combine these as needed.

  The external appearance seen from the bottom side of one embodiment of the shrink package according to the present invention is shown in FIG. 1, and its disassembled state is schematically shown in FIG. The shrink package 10 in the present embodiment is composed of a transparent shrink film 20 and two boxes of tissue cartons 30 shrink-wrapped by the shrink film 20, but is not limited thereto. If necessary, three or more tissue cartons 30 may be stacked in the same direction and shrink-wrapped.

  The individual tissue cartons 30 as articles according to the present invention have a bottom surface 30B, a top surface (not shown) opposite to the bottom surface 30B, a pair of laterally long sides, ie, a front surface 30F and a rear surface (not shown), and a pair of left and right sides. (Only the left side surface 30L is shown). A predetermined number of tissues (not shown) are accommodated in the tissue carton 30 in a folded state. On the bottom surface 30B of the tissue carton 30 as the first surface of the article in the present invention, the first barcode 31 as the first identification code in the present invention including information on the tissue carton 30 is printed.

  Only the coloring portions 21 and 22 and the misregistration identifying portion 23 printed on the shrink film 20 are extracted and enlarged and shown in FIG. On a part of the transparent shrink film 20, a first coloring unit 21, a second coloring unit 22, and a misregistration recognition unit 23 are printed.

  The first coloring unit 21 includes a second barcode 21a as a second identification code in the present invention including information on the shrink package 10, an arbitrary character 21b, a second barcode 21a, and a character 21b. And surrounding single colored surface layer 21c. Examples of the optional character 21b include an identification mark for indicating a material conforming to the Containers and Packaging Recycling Law, and a display of the number and size of various slogans or tissues. In the present embodiment, the single-colored surface layer 21c surrounds the entire second barcode 21a and the optional character 21b, but at least a portion of the second barcode 21a and the optional character 21b. It is also possible to do so. The first coloring portion 21 is disposed to face at least the outwardly exposed bottom surface 30B of the two pack tissue cartons 30 and to cover at least the first barcode 31 printed on the bottom surface 30B. . In this embodiment, even if the position of the second bar code 21a is slightly deviated from the first bar code 31, the first bar code is formed by the single colored surface layer 21c surrounding the second bar code 21a. It is possible to make 31 invisible.

  The second coloring portion 22 is disposed to face the front surface 30F of the tissue carton 30 positioned below the first bar code 31 covered by the first coloring portion 21. The second coloring unit 22 has an optional character 22 b and a single coloring surface layer 22 c surrounding at least a part of the character 22 b as required. The optional character 22b may be, for example, for clearly indicating that it is a two-pack tissue carton 30. The single-colored surface layer 22c of the second colored portion 22 may be the same as the single-colored surface layer 21c of the first colored portion 21, which can reduce the printing cost.

  The positional deviation identification unit 23 for identifying the degree of relative positional deviation between the first coloring unit 21 and the first bar code 31 covered by the first coloring unit 21 includes the first and second coloring units. It is located between the parts 21 and 22 and is formed continuously to the two colored parts 21 and 22. The misalignment identification unit 23 in the present embodiment has the same single-colored surface layer 23 c as the single-colored surface layers 21 c and 22 c of the first and second colored portions 21 and 22. The positional deviation identification unit 23 faces the bottom surface 30B and the front surface 30F of the lower tissue carton 30 covered with the first bar code 31 by the first coloring unit 21 and the ridge 32 therebetween. Will be distributed. It is preferable that the height (width) of the misalignment identification unit 23 along the direction orthogonal to the longitudinal direction of the weir 32 be 30 mm or less. In this case, although the maximum allowable value of the positional deviation of the first and second colored portions 21 and 22 along the direction orthogonal to the longitudinal direction of the weir 32 is 15 mm, it is not limited thereto.

In the present embodiment, the length along the ridge 32 of the misplacement identification portion 23 facing the ridge 32 is the length along the direction orthogonal to the ridge 32 between the bottom surface 30B and the front surface 30F of the tissue carton 30. It is set to be longer as you move away from 32. As a result, both end sides in the width direction of the misalignment identification unit 23 along the ridge 32 have a recessed shape. Therefore, when the weir 32 is located in this recessed portion, it may be determined that the positional deviation of the first and second colored parts 21 and 22 causing a problem with the tissue carton 30 has not occurred. it can. More specifically, when the length of the misalignment identification unit 23 along the ridge 32 is between the minimum value L _N and the threshold L _A , the position in the direction orthogonal to the ridge 32 of the tissue carton 30 It is possible to judge that the deviation is within the allowable range, and it is also possible to identify this optically. In this case, it is preferable that the difference between the minimum value L _N and the threshold value L _A is 2 mm or more and the above-mentioned threshold value L _A is in the range of 1.01 to 2.00 times the minimum value L _N. It is not limited to. In the present embodiment, the threshold value L _A is set to 1.05 times the minimum value L _N.

  Further, in the present embodiment, at least a part of each of the character 21 b of the first coloring unit 21 and the character 22 b of the second coloring unit 22 is disposed in contact with the misregistration recognition unit 23. Thereby, the degree of deviation of the relative position between the first colored portion 21 and the first bar code 31 in the direction orthogonal to the ridge 32 between the bottom surface 30B and the front surface 30F of the tissue carton 30 is easily identified. be able to. That is, when the characters 21b and 22b of the first and second coloring portions 21 and 22 partially overlap the ridge 32 between the bottom surface 30B and the front surface 30F of the tissue carton 30, the first and second colorings are performed. It can be determined that the positions of the parts 21 and 22 are improper. More specifically, it can be grasped that the first and second coloring parts 21 and 22 are largely misaligned in the direction orthogonal to the ridge 32 of the tissue carton 30 with respect to the tissue carton 30.

  It is also possible to print in advance so that a part of the character 21 b of the first color part 21 and the character 22 b of the second color part 22 enter the misregistration identification part 23. It is also possible to arrange another character. In this case, the presence or absence of positional deviation of the first and second coloring parts 21 and 22 may be determined based on the length of the positional deviation identification unit 23 along the ridge 32 described above.

  In the present embodiment, the first and second coloring units 21 and 22 and the misalignment identification unit 23 further include the common underlayer 24. The second bar code 21a and the single-colored surface layers 21c, 22c, and 23c are formed on the underlayer 24 so as to improve the clarity of the single-colored surface layers 21c, 22c, and 23c. . In this case, a white paint is generally used as the base layer 24, but the invention is not limited thereto. Further, at least one of the character 21b of the first colored portion 21 and the character 22b of the second colored portion 22 is formed of only the underlayer 24 not including the single colored surface layers 21c and 22c, and thereby the printing cost can be reduced. It is possible to suppress. However, it is also possible to print characters 21 b and 22 b of different hues from the single-colored surface layers 21 c and 22 c simultaneously with the single-colored surface layers 21 c and 22 c without forming such an underlayer 24.

  For example, the heating junctions and the heat shrinking parts (not shown) of the shrink film 20 on which the first and second colored parts 21 and 22 and the misregistration identification part 23 are printed are set as follows, for example. That is, the position other than the bottom surface 30B and the front surface 30F of the tissue carton 30, more specifically, the position facing the back surface of the tissue carton 30, a pair of left and right side surfaces, and a ridge other than the ridge 32 between the bottom surface 30B and the front surface 30F. Is preferably set.

  Such a shrink package 10 is packaged as follows. That is, first, two tissue cartons 30 are stacked one on top of the other, and the lower surface of the tissue carton 30 positioned on the upper side and the upper surface of the tissue carton 30 positioned on the lower side overlap each other. Place on shrink film 20. In this case, the first bar coat 31 printed on the bottom surface 30B of the tissue carton 30 located on the lower side overlaps the second bar code 21a of the first coloring portion 21 printed on the shrink film 20. The position of the tissue carton 30 is properly set. Next, the shrink film 20 is folded along the ridges 32 of the tissue carton 30 to heat-seal the overlapping joints, ie, the heat joints. Furthermore, a portion of the shrink film 20 which is slack relative to the tissue carton 30, that is, a heat-shrinkable portion is heated so as to be thermally shrunk so that the shrink film 20 adheres to the surface of the tissue carton 30. In addition, it is desirable to set the heating joint and the heat-shrinkage on the side surface and the back surface of the tissue carton 30 where the first and second colored parts 21 and 22 and the misregistration identification part 23 do not face each other. As I said.

  In the embodiment described above, both end sides in the width direction of the misregistration recognition unit 23 along the weir 32 are recessed, but the length along the weir 32 of the misregistration recognition unit 23 facing the weir 32 is the weir 32 The distance from the ridge 32 may be shorter along the direction orthogonal to

The other forms of the coloring units 21 and 22 and the misregistration identifying unit 23 according to the present invention are shown in FIG. 4, but the elements having the same functions as those of the previous embodiment are indicated by the same reference numerals. I omit explanation. That is, the colored portions 21 and 22 and the misregistration identifying portion 23 in the present embodiment have a contour shape that protrudes to the left and the right in the width direction both end sides of the misregistration identifying portion 23 along the ridge 32 of the tissue carton 30. Therefore, when the ridge 32 is located at this projecting portion, it may be determined that the positional deviation of the first and second colored parts 21 and 22 causing a problem with the tissue carton 30 does not occur. it can. More specifically, if the length L of the misregistration identification unit 23 along the ridge 32 is between the maximum value L _X and the threshold L _A , the direction orthogonal to the ridge 32 of the tissue carton 30 is obtained. It is possible to judge that the positional deviation is within the allowable range, and it is also possible to optically identify this. In this case, it is preferable that the difference between the maximum value L _X and the threshold value L _A is 2 mm or more and the above-mentioned threshold value L _A is in the range of 0.70 to 0.99 times the maximum value L _X. It is not limited to.

  In the present embodiment, the displacement identification unit 23 has a surface pattern different from that of the first and second coloring units 21 and 22 to make the displacement identification unit 23 clear. Specifically, the single-colored surface layer 23c which is the same as the first and second colored portions 21 and 22 are regularly arranged at predetermined intervals with respect to the transparent shrink film 20, but the present invention is not limited thereto. As described above, when the positional deviation identification unit 23 has a surface pattern different from that of the first and second colored parts 21 and 22, the degree of relative position deviation between the first colored part 21 and the first barcode 31 Can be easily identified. In particular, in the case where the surface pattern is formed on the same single-colored surface layer 23c as the first and second colored portions 21 and 22 as in the present embodiment, there is no concern that the printing cost is increased.

  Even when the lengths of the first coloring unit 21 or the second coloring unit 22 and the displacement identification unit 23 along the ridge 32 are the same, the displacement identification unit 23 is not limited to the first and second coloring units 21. , 22 can be used to determine the degree of positional deviation.

The other forms of the coloring units 21 and 22 and the misregistration identifying unit 23 according to the present invention are shown in FIG. 5, but the elements having the same functions as those of the previous embodiment are indicated by the same reference numerals. I omit explanation. That is, the outline shapes of the first and second coloring parts 21 and 22 and the misalignment identification part 23 in the present embodiment are set to be substantially rectangular. Further, the lengths L ₁ and L _{2 of} the first and second colored parts 21 and 22 and the length L of the misalignment identification part 23 along the ridge 32 of the tissue carton 30 are set to be substantially the same. However, the misalignment identification unit 23 offsets the first and second coloring units 21 and 22 by a predetermined amount L _{S in} the left or right direction (right direction in the illustrated example) along the ridge 32 of the tissue carton 30. It is done. Therefore, if the distance L ₀ from the right side surface 30 R of the tissue carton 30 to the misregistration identification unit 23 at the original position becomes, for example, the distance L _{B to} the first or second coloring unit 22, the first and second It can be determined that the position of the second coloring unit 22 is nonconforming. More specifically, it can be judged that the positional deviation of the first and second colored parts 22 in the direction orthogonal to the ridge 32 of the tissue carton 30 is out of the allowable range, which is an optical condition. It is also possible to identify

  As shown in FIG. 4, when the misregistration identification unit 23 has a surface pattern different from that of the first and second coloring units 21 and 22, the first and second coloring units 21 and 21 for the tissue carton 30 The degree of positional deviation of 22 can be grasped. In this case, it is not necessary to offset the positional deviation identification unit 23 with the first and second colored portions 21 and 22 along the ridge 32. In addition, if it is not necessary to consider the printing cost, the hues of the single-colored surface layers 21c, 22c and 23c of the first and second colored parts 21 and 22 and the misregistration identification part 23 should be different. Can. Similarly, it is also possible to form patterns of predetermined patterns different from one another on these single-colored surface layers 21c, 22c and 23c.

  Although the embodiment described above is directed to the tissue carton 30, a plurality of identical articles each having a first surface and a second surface adjacent to the first surface via a weir are integrated by a transparent film. In the case of packaging, the present invention can be applied as appropriate. In addition, the present invention can be applied even when mechanically sticking the colored portions 21 and 22 and the positional deviation identification portion 23 printed as a label on a transparent film before or after packing. It is.

  Thus, the present invention should be construed only from the matters described in the claims, and in the embodiment described above, the matters described in all the changes and modifications included in the concept of the present invention. Other than possible. That is, all the matters in the above-mentioned embodiment are not for limiting the present invention, and may be arbitrarily changed according to the use, purpose, etc. including the composition which is not directly related to the present invention. It is a thing.
