[0005] Patent Document 1: Japanese Patent Application Laid-Open No. 10-316168 Summary of the invention

[0006] Problems to be solved by the invention

[0007] A container containing food (e.g., ready-to-eat food) is subjected to prescribed printing (e.g., printing including product name, food ingredients, etc.). This printing is applied to the outer surface of the container so that the purchaser can confirm the product before purchasing it. However, if an information recording code is provided on the outer surface of the container, it may be improperly read before purchase. Therefore, previously, a method of providing the information recording code on the inner side of the cover body was more commonly used, but the information recording code must be formed by using special ink that does not affect the food, or by processing such that the ink does not directly contact the food. Due to the above situation, the information recording code is provided on the inner surface of the container, and thus there is a tendency for the manufacturing cost of the product to become higher. Therefore, it is required that the information recording code with information for the purchaser is still provided on the outer surface of the container.

[0008] Therefore, an object of the present invention is to provide a package and a method for manufacturing a package, wherein even if an information recording code recording information for a purchaser is provided on an outer surface side, the information recording code is difficult to be illegally read.

[0009] Means for solving problems

[0010] A packaging body according to one aspect of the present invention comprises: a container having a container body for storing food and having an opening on the side opposite to the bottom, and a cover body for blocking the opening; and a transparent heat shrink film for packaging a part or the whole of the container, wherein the cover body comprises: a cover body mounted on the end of the container body forming the opening; and a gripping piece extending outward from the cover body in a top view of the cover body, and an information recording code is printed on the side of the cover body opposite to the container body in a manner that crosses the boundary between the cover body and the gripping piece, and the gripping piece is bent toward the body of the container body when a part or the whole of the container is packaged by the heat shrink film. In the present invention, the concept of "printing" also includes the concept of "printing".

[0011] In the above-mentioned packaging body, the information recording code is printed on the outer surface side of the cover body of the container. The information recording code is printed in a manner that straddles the boundary between the above-mentioned cover body and the above-mentioned holding piece, and in a state where a part or the whole of the above-mentioned container is wrapped by the above-mentioned heat shrink film, the above-mentioned holding piece is bent toward the body side of the above-mentioned container body. In this case, the information recording code is also bent in accordance with the bending of the holding piece. Therefore, even if the information recording code is printed on the outer surface side of the cover body, the information recording code as a whole is not arranged on the same plane. In this case, the information recording code cannot be read as a whole. As a result, the information recording code is difficult to be improperly read before the packaging body is purchased.

[0012] Alternatively, the information recording code may be a two-dimensional code having a quadrilateral shape having a first corner, a second corner, a third corner and a fourth corner, and a first position correction pattern, a second position correction pattern and a third position correction pattern for correcting the position of the information recording code are formed at the first corner, the second corner and the third corner, and the first position correction pattern, the second position correction pattern and the third position correction pattern are formed on the cover in such a way that they cannot be read at one time when a part or the whole of the container is wrapped by the heat shrink film.

[0013] In the above configuration, the first position correction pattern, the second position correction pattern, and the third position correction pattern cannot be read at once. In this case, the position correction of the information recording code cannot be properly implemented, so the information recording code cannot be read. This can further prevent the information recording code from being illegally read.

[0014] Alternatively, the information recording code may be a two-dimensional code in the shape of a quadrilateral having a first corner, a second corner, a third corner and a fourth corner, and a first position correction pattern, a second position correction pattern and a third position correction pattern for correcting the position of the information recording code are formed at the first corner, the second corner and the third corner, and one of the first position correction pattern, the second position correction pattern and the third position correction pattern is located on the holding piece, and at least one of the remaining two is located on the cover body.

[0015] In this case, since the first position correction pattern, the second position correction pattern, and the third position correction pattern do not exist on the same plane, it is difficult to read them at once.

[0016] Alternatively, the first position correction pattern may be located on the cover body, the second position correction pattern and the third position correction pattern may be located on the boundary, and the third position correction pattern may be located on the holding piece. In this case, the first position correction pattern, the second position correction pattern and the third position correction pattern may not be located on the same plane, so it is difficult to read them all at once.

[0017] Alternatively, when a part or the entire container is wrapped in the heat shrink film, wrinkles may be formed on the holding sheet. In this case, the information recording code is further deformed due to the wrinkles, making it difficult to read the information recording code.

[0018] The manufacturing method of the packaging body according to another aspect of the present invention comprises: a process of preparing a container, the container comprising a container body for storing food, and a cover body for blocking the above-mentioned opening of the above-mentioned container body; and a process of packaging a part or the whole of the above-mentioned container with a transparent heat-shrinkable film, the above-mentioned cover body comprising: a cover body, which is installed on the end of the above-mentioned container body that forms the above-mentioned opening; and a holding piece, which extends outward from the above-mentioned cover body in a top view of the above-mentioned cover body, and an information recording code is printed on the side of the above-mentioned cover body opposite to the above-mentioned container body in a manner that straddles the boundary between the above-mentioned cover body and the above-mentioned holding piece, and in the process of packaging the above-mentioned container with the above-mentioned heat-shrinkable film, a part or the whole of the above-mentioned container is packaged with the above-mentioned heat-shrinkable film in a manner that the above-mentioned holding piece is bent toward the body side of the above-mentioned container body.

[0019] In the above-mentioned manufacturing method, a package body in which an information recording code is printed on the outer surface side of a cover body of a container can be manufactured. In the package body manufactured by the above-mentioned manufacturing method, the information recording code is printed in a manner that straddles the boundary between the above-mentioned cover body and the above-mentioned holding piece, and when a part or the whole of the above-mentioned container is wrapped by the above-mentioned heat shrink film, the above-mentioned holding piece is bent toward the body side of the above-mentioned container body. In this case, the information recording code is also bent in accordance with the bending of the holding piece. Therefore, even if the information recording code is printed on the outer surface side of the cover body, the information recording code as a whole will not be read as an information recording code arranged on the same plane. As a result, it is possible to prevent the information recording code from being read before the package body is purchased.

[0020] Alternatively, in the step of packaging a part or the whole of the container with the heat shrink film, the part or the whole of the container may be packaged with the heat shrink film in such a manner that wrinkles are formed on the holding sheet. In this case, the information recording code printed on the cover of the manufactured package is further deformed by the wrinkles. As a result, it is difficult to read the information recording code.

[0021] Effects of the Invention

[0022] According to the present invention, it is possible to provide a package and a method for manufacturing a package, wherein even if an information recording code recording information for a purchaser is provided on an outer surface side, the information recording code is difficult to be illegally read.

[0032] Below, while referring to the attached Figure 1 The embodiments of the present invention will be described. The same reference numerals are attached to the same elements. Repeated descriptions are omitted. The dimensional ratios of the drawings are not necessarily consistent with the ratios of the description.

[0033] Figure 1 is a side view of a package according to one embodiment. Figure 2 yes Figure 1 The package shown has a side view of a container. Figure 3 yes Figure 2 A top view of the container shown (viewed from the cover side). Figure 4 It is along Figure 3 Schematic diagram of the cross-section of line IV-IV. Figure 5 yes Figure 2 A top view of the container shown having a cover.

[0034] Figure 1 The package 1 shown in the figure comprises a container 2 and a transparent heat shrinkable film 3. Figure 2 as well as Figure 4 As shown, the container 2 contains ready-to-eat food 4. The ready-to-eat food 4 is, for example, food that is cooked by pouring hot water. The heat shrink film 3 is a transparent film that wraps the container 2. The heat shrink film 3 is transparent, so the container 2 can be visually confirmed through the heat shrink film 3. However, in Figure 1 In the figure, in order to show that the container 2 is wrapped by the heat shrink film 3, the container 2 located inside the heat shrink film 3 is shown by a dotted line. The package 1 will be described in detail.

[0035] [container]

[0036] like Figure 1 to Figure 4 As shown, the container 2 includes a container body 10 and a lid 20. The container 2 is formed by sealing the container body 10 containing the instant food 4 with the lid 20.

[0037] <Container body>

[0038] like Figure 2 as well as Figure 4As shown, the container body 10 has a bottom 11 and a body 12. The bottom 11 and the body 12 form a storage space S for storing the ready-to-eat food 4. In one embodiment, the shape of the container body 10 is cup-shaped or box-shaped. In this embodiment, the top view shape of the container body 10 (the shape observed from the thickness direction of the bottom 11) is circular. The top view shape of the container body 10 is not limited to a circle, and may also be a quadrilateral (e.g., a rectangle or a square).

[0039] In the present embodiment, the top view shape of the bottom 11 is circular. The top view shape of the bottom 11 is not limited to a circle, and may be a quadrilateral (for example, a rectangle or a square).

[0040] The body 12 is provided along the periphery of the bottom 11 and rises from the periphery of the bottom 11. The body 12 is provided integrally with the bottom 11. The opening 10a is formed by an end 12a of the body 12 on the opposite side to the bottom 11. The end 12a is a flange-shaped end extending outward.

[0041] The material of the container body 10 (i.e., the bottom 11 and the body 12) is not limited as long as it is a material of a container for storing the ready-to-eat food 4. For example, the material of the container body 10 may be a thermoplastic resin. Examples of thermoplastic resins include polyethylene resins, polypropylene resins, polystyrene resins, etc. The container body 10 may also be a paper container body (e.g., a container body in which the mass of paper is 51% or more relative to the total mass).

[0042] <Cover>

[0043] like Figure 5 As shown, the cover body 20 has a cover body 21, a gripping piece 22 and a gripping piece 23 in a plan view. As described later, Figure 5 2 is a diagram showing the holding piece 22 and the holding piece 23 in an unbent state. Figure 5 In the figure, for convenience of explanation, the boundaries between the cap body 21 and the holding pieces 22 and 23 are schematically shown by dotted lines.

[0044] like Figure 1 to Figure 4 As shown, the cap body 21 is a component that blocks the opening 10a of the container body 10. The top view shape of the cap body 21 is the same as the top view shape of the end 12a, and is circular in this embodiment. Although not shown in the figure, a predetermined printing (e.g., printing of a product name, ingredients of the instant food 4, etc.) is implemented on the outer surface side of the cap body 21.

[0045] like Figure 5As shown, the holding piece 22 and the holding piece 23 extend continuously outward from the periphery of the cover body 21. The holding piece 22 and the holding piece 23 are, for example, tabs. When the cover body 20 is mounted on the container body 10, the holding piece 22 and the holding piece 23 are located outside the end 12a. At least one of the holding piece 22 and the holding piece 23 is used as the opening start end when the purchaser of the package body 1 opens the container 2, and is also used as a locking tool for fixing the cover body 20 to the container body 10 when the opening 10a of the container body 10 is blocked again by the cover body 20. The holding piece 22 and the holding piece 23 are in the shape of a tongue or a roughly triangular shape.

[0046] The cover 20 is a laminate including a base material layer and a thermal adhesive resin layer. When the cover 20 is attached to the container body 10, the base material layer and the thermal adhesive resin layer are arranged in this order from the outside (opposite to the container body 10).

[0047] The substrate layer is, for example, a layer made of paper itself. In the present embodiment, the substrate layer is equivalent to the outer layer of the cover body 20. Paper constituting the substrate layer is, for example, high-quality paper (chemical pulp paper, also called high-grade paper), special high-quality paper, coated paper, coated paper, cast-coated paper, Japanese paper, molded paper, kraft paper, etc. The substrate layer can also be made of recycled paper. The mass of the substrate layer accounts for, for example, more than 51% of the total mass of the layers constituting the laminated sheet, i.e., the cover body 20 (i.e., the total mass of the cover body 20). In this case, the cover body 20 is a paper cover body (a cover body with paper as the main component).

[0048] The heat-adhesive resin layer is the inner layer of the cover 20, and is a layer for bonding the cover 20 to the end 12a of the container body 10. The heat-adhesive resin layer is, for example, a sealing layer. An example of a material for the heat-adhesive resin layer is a polyolefin resin. As the material for the heat-adhesive resin layer, specifically used are: low-density polyethylene resin (LDPE), medium-density polyethylene resin (MDPE), linear low-density polyethylene resin (LLDPE), ethylene-vinyl acetate copolymer (EVA), ethylene-α-olefin copolymer, ethylene-methacrylic acid resin copolymer and other ethylene resins, mixed resins of polyethylene and polybutene, homopolymer polypropylene resin (PP), propylene-ethylene random copolymer, propylene-ethylene block copolymer, propylene-α-olefin copolymer and other polypropylene resins, etc. The heat-adhesive resin layer can be formed, for example, by a method (extrusion lamination method) of extruding the resin that should become the heat-adhesive resin layer.

[0049] The cover 20 may have other layers in addition to the base material layer and the thermal adhesive resin layer. For example, the cover 20 may have a metal layer between the base material layer and the thermal adhesive resin layer to provide shielding properties to the cover 20. The metal layer is, for example, a metal foil, and an example of the metal foil is aluminum foil.

[0050] like Figure 1 to Figure 5 As shown, the information recording code 30 is printed on the outer surface side of the cover 20 in such a manner that the information recording code 30 can be read from the outside when the container 2 is wrapped by the heat shrink film 3. For example, the information recording code 30 is printed on the surface of the cover 20 (corresponding to the surface of the above-mentioned base material layer possessed by the cover 20). In this embodiment, the information recording code 30 is a code recording the information for the purchaser of the packaging body 1. The information for the purchaser includes promotional information, product information, etc. specially provided to the purchaser.

[0051] In the present embodiment, the information recording code 30 is a two-dimensional code. The information recording code 30 is in a quadrilateral shape (e.g., a square). The information recording code 30 has a first corner 30a, a second corner 30b, a third corner 30c, and a fourth corner 30d. The information recording code 30 has a first position correction pattern 31a, a second position correction pattern 31b, and a third position correction pattern 31c at the first corner 30a, the second corner 30b, and the third corner 30c.

[0052] The first position correction pattern 31a, the second position correction pattern 31b, and the third position correction pattern 31c are patterns necessary for accurately reading the information recording code 30, and are patterns for correcting the position (including the orientation, etc.) of the information recording code 30. An example of the information recording code 30 as a two-dimensional code is a QR code (registered trademark). The first position correction pattern 31a, the second position correction pattern 31b, and the third position correction pattern 31c are equivalent to the positioning pattern (extraction mark) in the two-dimensional code (registered trademark).

[0053] The information recording code 30 is printed on the cover body 20 in a manner that straddles the boundary 21a (the periphery of the cover body 21) between the cover body 21 and the gripping sheet 22. In other words, the information recording code 30 has an area printed on the cover body 21 and an area printed on the gripping sheet 22. For example, the area of ​​the area printed on the gripping sheet 22 of the information recording code 30 may be 30% or more and 70% or less of the entire area of ​​the information recording code 30. Alternatively, the area of ​​the area printed on the cover body 21 and the area printed on the gripping sheet 22 of the information recording code 30 may each be approximately 50% of the entire area of ​​the information recording code 30.

[0054] In one embodiment, one of the first position correction pattern 31a, the second position correction pattern 31b, and the third position correction pattern 31c may be arranged on the gripping piece 22, and at least one of the remaining two may be arranged in an area outside the gripping piece 22. The manner in which one of the first position correction pattern 31a, the second position correction pattern 31b, and the third position correction pattern 31c is arranged in an area outside the gripping piece 22 includes a case where it is arranged on the cover body 21 and a case where it is arranged on the boundary 21a. In this embodiment, the information recording code 30 is as shown in FIG. Figure 5 As shown, the second position correction pattern 31b is arranged on the holding piece 22, and the first position correction pattern 31a and the third position correction pattern 31c are arranged on the boundary 21a.

[0055] In one embodiment, the information recording code 30 may also be as follows Figure 6 As shown, the first position correction pattern 31 a and the second position correction pattern 31 b are printed on the cover body 20 so as to be located on the gripping piece 22 and the third position correction pattern 31 c is located on the cover body 21 . Figure 6 The method shown corresponds to Figure 5 The arrangement state of the information recording code 30 shown is an arrangement state after being rotated 45 degrees.

[0056] The cover body 20 is manufactured, for example, as follows. First, the laminated sheet including the substrate layer and the thermal adhesive resin layer is manufactured, for example, by extrusion lamination, dry lamination, etc. For example, the laminated sheet is processed into the shape of the cover body 20 by cutting, etc. The above-mentioned prescribed printing is performed on the outer side of the cover body 20. The information recording code 30 is printed on the outer side of the cover body 20. This printing can be pre-performed on the area of ​​the laminated sheet corresponding to the cover body 20 before the laminated sheet is processed into the shape of the cover body 20, or it can be performed on the cover body 20 after the laminated sheet is processed into the cover body 20. The ink used for printing the information recording code 30 can be any gravure ink, inkjet ink, etc. used for barcodes, two-dimensional codes (registered trademark), etc.

[0057] The container 2 including the container body 10 and the lid 20 is manufactured by joining the lid 20 and the end 12a so as to close the opening 10a of the container body 10. The lid 20 and the end 12a are heat-sealed, for example.

[0058] [Heat shrink film]

[0059] The heat shrink film 3 is a film that wraps a part or the whole of the container 2. When the heat shrink film 3 wraps a part of the container 2, the heat shrink film 3 wraps the joint portion between the lid 20 and the container body 10. In this case, the periphery of the lid 20 and the end 12a of the container body 10 are wrapped by the heat shrink film 3. Figure 1 The case where the entire container 2 is packaged with the heat shrink film 3 as shown will be described as an example.

[0060] The heat shrink film 3 is a film that shrinks due to heat. The heat shrink film 3 is in a state of matching the outer shape of the container 2. An example of the heat shrink film 3 is a shrink film. Examples of the material of the heat shrink film 3 include polyvinyl chloride resin, polypropylene resin, polyethylene resin, polystyrene resin, polyolefin resin, polyethylene terephthalate resin, etc.

[0061] In the package 1, as Figure 1 to Figure 4 As shown, the holding pieces 22 and 23 are wrapped by the heat shrink film 3 in a state of being bent toward the body 12 of the container body 10. At this time, the holding piece 22 may be bent in a manner that wrinkles are generated in the holding piece 22. In one embodiment of the package 1 in which the container 2 is wrapped by the heat shrink film 3, the holding pieces 22 and 23 may be bent so that a part of them contacts the body 12. In one embodiment, the holding pieces 22 and 23 may be bent by more than 90 degrees.

[0062] [Method for producing packaging body]

[0063] The package body 1 is produced by preparing a container 2 containing the ready-to-eat food 4 (preparation step), and packaging the container 2 with a heat shrink film 3 (packaging step).

[0064] In the above preparation process, the instant food 4 is stored in the container body 10, and the container body 10 is sealed by the cover body 20 printed with the information recording code 30. Thus, the container 2 storing the instant food 4 can be obtained. The cover body 20 is attached to the container body 10 by heat sealing, for example.

[0065] In the packaging process, the container 2 is covered with the heat shrink film 3, and the heat shrink film 3 is shrunk by heat. That is, in the packaging process, the container 2 is shrink-packaged by the heat shrink film 3. In the packaging process, the container 2 is covered with the heat shrink film 3 in a manner that the holding piece 22 and the holding piece 23 are bent toward the body 12. The heat shrink film 3 shrinks by heat to match the container 2, so that the bent state of the holding piece 22 is maintained in the packaging body 1. In the packaging process, the container 2 may be packaged by shrinking the heat shrink film 3 in a manner that the holding piece 22 is bent as described above and wrinkles are generated in the holding piece 22.

[0066] An information recording code 30 is printed on the cover 20 of the container 2. The information recording code 30 is printed on the surface side of the cover 20. The container 2 is wrapped with a heat shrink film 3. The heat shrink film 3 is transparent, so even if the container 2 is wrapped with the heat shrink film 3, the information recording code 30 can be visually confirmed.

[0067] The information recording code 30 is printed on the cover body 20 in such a manner as to cross the boundary 21a between the cover body 21 and the holding piece 22. When the container 2 is wrapped with the heat shrink film 3, the holding piece 22 is bent toward the body 12. As described above, a part of the information recording code 30 is printed on the holding piece 22, so the information recording code 30 is also bent at the boundary between the cover body 21 and the holding piece 22 (in other words, the end 12a of the container body 10). That is, the information recording code 30 as a whole is not on the same plane. Therefore, when the information recording code 30 is read by a code reader (including a reading application), a part of the information recording code 30 is missing or deformed from the perspective of the code reader. Therefore, the information recording code 30 as a whole cannot be correctly read by the code reader.

[0068] On the other hand, the purchaser of the package 1 can read the information recording code 30 as follows. First, the container 2 is taken out from the heat shrink film 3. Next, the bending of the gripping piece 22 is eliminated so that the cover body 21 and the gripping piece 22 are substantially in the same plane. Thereafter, the information recording code 30 is read by a code reader. In this way, the purchaser of the package 1 can read the information recording code 30.

[0069] Although in Figure 2 , Figure 4 Although not shown in the figure, the product name of the package 1 as a commodity, the ingredients of the ready-to-eat food 4, etc. are printed on the surface side of the cover 20. The information recording code 30 is also printed on the surface side of the cover 20 where such printing is performed. Therefore, for example, in the process of printing the product name of the package 1 as a commodity, the ingredients of the ready-to-eat food 4, etc., it is also possible to print the information recording code 30 on the cover 20. In this way, when the information recording code 30 is also printed on the cover 20 in the process of printing the product name, etc., it is not necessary to provide another process for printing the information recording code 30. Therefore, compared with the case where another process is provided, the manufacturing process of the package 1 is simplified, and the increase in manufacturing cost can be prevented.

[0070] In addition, since the information recording code 30 is provided on the surface side of the cover body 20, there is no need to perform additional processing such as preventing the ink from directly contacting the ready-to-eat food 4. Therefore, the manufacturing process of the package body 1 is simplified, and an increase in manufacturing cost can be prevented. The information recording code 30 printed on the surface side of the cover body 20 does not contact the ready-to-eat food 4, so the ink used for printing the information recording code 30 does not need to use special inks that are assumed to contact food. Therefore, compared with the case of preparing the above-mentioned special ink, the manufacturing cost can be reduced.

[0071] The information recording code 30 records information (e.g., information for guiding sales promotion, etc.) provided to the purchaser of the package 1 as a commodity, for example. In the package 1, even if the information recording code 30 is printed on the outer surface side of the cover 20, the information recording code 30 cannot be correctly read when the container 2 is wrapped with the heat shrink film 3. Therefore, it is possible to prevent the information recording code 30 from being illegally read before the package 1 is purchased.

[0072] For example, in a mode where the area of ​​the region printed on the gripping sheet 22 in the information recording code 30 accounts for 30% or more and 70% or less of the entire area of ​​the information recording code 30, when the information recording code 30 is observed in a state where the container 2 is wrapped with the heat shrink film 3, it is difficult to visually confirm the entire information recording code 30, or a part of the information recording code 30 is deformed and visually confirmed as an incorrect pattern. As a result, it is difficult to correctly read the information recording code 30 by a code reader, and as a result, it helps to prevent the illegal reading of the information recording code 30. The same is true for a mode where the area of ​​the information recording code 30 printed on the cover body 21 and the area printed on the gripping sheet 22 in the information recording code 30 are each about 50% of the entire area of ​​the information recording code 30.

[0073] In a mode in which the information recording code 30 is a two-dimensional code having a first position correction pattern 31a, a second position correction pattern 31b, and a third position correction pattern 31c for correcting the position of the information recording code 30, by reading the first position correction pattern 31a, the second position correction pattern 31b, and the third position correction pattern 31c all at once, the orientation of the information recording code 30 can be correctly determined, and as a result, the information recording code 30 can be read. Thus, in a mode in which the information recording code 30 is printed on the cover body 20 in a state in which the first position correction pattern 31a, the second position correction pattern 31b, and the third position correction pattern 31c cannot be read at once in a state in which the container 2 is wrapped with the heat shrink film 3, it is possible to further prevent the information recording code 30 from being improperly read.

[0074] In a mode in which one of the first position correction pattern 31a, the second position correction pattern 31b, and the third position correction pattern 31c is disposed on the gripping piece 22, and one of the remaining two is formed in a region outside the gripping piece 22, the first position correction pattern 31a, the second position correction pattern 31b, and the third position correction pattern 31c cannot be read at once by bending the gripping piece 22. Thus, it is possible to further prevent the information recording code 30 from being improperly read.

[0075] In the case where the second position correction pattern 31b among the first position correction pattern 31a, the second position correction pattern 31b and the third position correction pattern 31c are arranged on the holding piece 22, and the first position correction pattern 31a and the third position correction pattern 31c are formed on the boundary 21a, the holding piece 22 is bent so that the first position correction pattern 31a, the second position correction pattern 31b and the third position correction pattern 31c cannot be read at one time. Thus, the illegal reading of the information recording code 30 can be further prevented. The boundary 21a and its vicinity correspond to the bent corners, so the first position correction pattern 31a and the third position correction pattern 31c located on the boundary 21a are deformed. Therefore, the first position correction pattern 31a and the third position correction pattern 31c themselves are difficult to read. Through this, the illegal reading of the information recording code 30 can also be further prevented.

[0076] When the container 2 is wrapped with the heat shrink film 3, the holding piece 22 is bent and wrinkled, and the information recording code 30 is twisted in accordance with the wrinkles. As a result, it is more difficult to read the information recording code 30 in the state where the container 2 is wrapped with the heat shrink film 3. As a result, it is possible to further prevent the unauthorized reading of the information recording code 30.

[0077] Next, an experimental example related to the cover body 20 having the information recording code 30 will be described. In the experimental example, the following first sample and second sample were used as the cover body 20.

[0078] (First sample)

[0079] The first sample is Figure 7The cover body 20 shown. The cover body 20 as the first sample is referred to as the cover body 20A. The cover body 20A has a cover body 21, and two pinching pieces 22, 23. The cover body 21 is circular with a diameter of about 97 mm. The pinching pieces 22, 23 extend outward from the periphery of the cover body 21. The pinching pieces 22, 23 are roughly triangular in shape. The distance between the first end 23a and the second end 23b of the pinching piece 23 is about 29 mm. The first end 23a and the second end 23b are the connecting parts between the outer edge of the pinching piece 23 and the cover body 21. The distance between the top 23c of the pinching piece 23 and the boundary 21a between the pinching piece 23 and the cover body 21 is about 13 mm. The pinching piece 22 is the same size as the pinching piece 23.

[0080] The cover body 20A has the following layer structure.

[0081] Printing layer / base material layer / first resin layer / aluminum foil / second resin layer / sealing layer

[0082] In the above layer structure, the printed layer is on the surface side of the cover body 20A, and the sealant layer is on the inner surface side of the cover body 20A.

[0083] The substrate layer is paper. Specifically, the substrate layer is Monken G single-sided coated paper (Monbran G sheet art; manufactured by Nippon Paper Industries, Ltd.). The grammage of the substrate layer is 79.1 g / m 2 .

[0084] The material of the first resin layer is polyethylene (PE). That is, the first resin layer is a PE layer. The thickness of the first resin layer is 13 μm.

[0085] The thickness of the aluminum foil was 6 μm.

[0086] The material of the second resin layer is PE. That is, the second resin layer is a PE layer. The thickness of the second resin layer is 25 μm.

[0087] The material of the sealing layer (thermal adhesive resin layer) is LLDPE, and the thickness of the sealing layer is 15 μm.

[0088] like Figure 7 As shown in FIG. 1 , in the cover 20A, as a part of the printed layer, a square-shaped information recording code 30 is printed on the cover 20A. The length of one side of the information recording code 30 is about 10.5 mm. The information recording code 30 has a first position correction pattern 31a, a second position correction pattern 31b, and a third position correction pattern 31c. The information recording code 30 is a two-dimensional code (registered trademark). Therefore, the first position correction pattern 31a, the second position correction pattern 31b, and the third position correction pattern 31c are positioning patterns (extraction marks) in the two-dimensional code (registered trademark).

[0089] The information recording code 30 is formed on the cover body 20 in such a manner as to cross the boundary 21a between the cover body 21 and the holding piece 23. Specifically, the first position correction pattern 31a arranged at the first corner 30a is located on the boundary 21a, the third position correction pattern 31c arranged at the third corner 30c is located near the boundary 21a, and the second position correction pattern 31b arranged at the second corner 30b is located at the holding piece 23.

[0090] In the cover body 20A, OP varnish (Overprint varnish) is applied on the printed layer.

[0091] (Second sample)

[0092] The second sample is Figure 8 The cover 20 shown. The cover 20 as the second sample is referred to as a cover 20B. The structure of the cover 20B is the same as that of the cover 20A except for the following points.

[0093] (1) The base material layer has a gram weight of 79.1 g / m 2 Golden Vine single-sided coated paper (manufactured by Oji Paper Co., Ltd.).

[0094] (2) Figure 8 As shown, the information recording code 30 which is a two-dimensional code (registered trademark) is formed at a position further outward (toward the outer edge of the gripping piece 23) than in the case of the cover body 20A.

[0095] (3) The varnish formed on the printed layer is a release varnish.

[0096] <Reading angle evaluation>

[0097] After the first and second samples were bonded to the container body 10 by heat sealing, the ease of reading the information recording code 30 according to the bending angle of the gripping piece 23 was evaluated.

[0098] (Evaluation test method)

[0099] Fig. 9 This is a schematic diagram for explaining the method of setting the bending angle of the holding piece 23 in the evaluation test. Fig. 9 In the present invention, the cover bodies 20A and 20B as the first and second samples are simply referred to as cover bodies 20. Fig. 9 In order to indicate the holding piece 23, the holding piece 23 is hatched.

[0100] like Fig. 9 As shown in FIG. 1 , the bending angle of the holding piece 23 is set while observing the container body 10 joined with the cover body 20 from the side through the indexer 40. Fig. 9As shown, the bending angle is set based on the position of the first end 23a of the holding piece 23. Specifically, when the container body 10 is left to stand and the holding piece 23 is not bent, the single-point dashed line L0 that coincides with the upper surface of the lid body 20 is defined as the position of the angle 0, and the holding piece 23 is set relative to the angle 0 (i.e., Fig. 9 The angle (the angle of the upper surface of the holding piece 23) relative to the single-point chain line L0 is defined as the bending angle. Fig. 9 For reference, positions at 45 degrees and 90 degrees relative to the one-dot chain line L0 are shown by the one-dot chain line L45 and the one-dot chain line L90.

[0101] In the reading angle evaluation, the iPhone (registered trademark) was used to evaluate whether the information recording code 30 (two-dimensional code (registered trademark)) could be read while bending the holding piece 23 by 5 degrees at a time from 0 degrees to 90 degrees. This evaluation was performed 5 times in each of the first sample and the second sample. In the reading performed by the iPhone (registered trademark), the iPhone (registered trademark) was configured in a manner that the maximum number of information recording codes 30 (two-dimensional code (registered trademark)) was contained in the camera area of ​​the camera of the iPhone (registered trademark) (in other words, the information recording code 30 was easy to read), and the reading was performed. Before the iPhone (registered trademark) performed the reading, the wrinkles of the holding piece 23 were stretched, and the reading was performed in a state where the holding piece 23 had no wrinkles.

[0102] (Evaluation results)

[0103] The evaluation results of the reading angle evaluation of the first sample and the second sample are shown in Table 1. "No. 1" to "No. 5" in Table 1 indicate the number of trials.

[0104]

Table 1

[0105]

[0106] As shown in Table 1, when the first sample (cover 20A) was used, reading was possible up to 45 degrees in No. 1 and No. 4, 50 degrees in No. 3, 55 degrees in No. 2, and 60 degrees in No. 5. Therefore, it can be understood that reading can be prevented as long as the bending angle of the holding piece 23 is 65 degrees or more.

[0107] When the second sample (cover 20B) was used, reading was possible up to 70 degrees in No. 1, No. 3, and No. 5, and up to 75 degrees in No. 2 and No. 3. Therefore, it can be understood that reading can be prevented as long as the bending angle of the grip piece 23 is 80 degrees or more.

[0108] It is believed that the reason why the maximum readable bending angle of the second sample (cover 20B) is larger than that of the first sample (cover 20A) is that Figure 8 As shown, in the cover body 20B, the information recording code 30 is located on the outer side than in the case of the cover body 20A.

[0109] According to the results shown in Table 1, it can be understood that when the two-dimensional code (registered trademark) is printed at a predetermined position (e.g., the position of the information recording code 30 in the first sample), reading can be prevented as long as the bending angle is 65 degrees or more. Moreover, it can be understood that reading can be further prevented if the bending angle is 80 degrees or more.

[0110] In the above evaluation test method, the reading evaluation was performed in a state where the container 2 (container body 10 with cover body 20 attached) was not wrapped with heat shrink film 3. When the container 2 is wrapped with heat shrink film 3, the gripping pieces 22 and 23 are usually bent to contact with the body portion 12 of the container body 10. In this case, the gripping pieces 22 and 23 are bent more than 90 degrees. Therefore, according to the results of Table 1, it can be understood that the prevention of improper reading of the information recording code 30 can be achieved in a state where the container 2 is wrapped with heat shrink film 3 (the state actually provided to the end user).

[0111] Furthermore, in the above-mentioned evaluation test method, when reading the above-mentioned information recording code 30, the information recording code 30 was read in the state where the holding sheet 23 was not wrinkled as described above. That is, the results in the above-mentioned Table 1 are the results in the state where it is relatively easy to read. Therefore, it can be understood that it is more difficult to read in the state where wrinkles are generated. In the state where the container 2 is wrapped with the heat shrink film 3, wrinkles are easily generated on the holding sheets 22 and 23, so it can be understood that it is more difficult to read the information recording code 30.

[0112] Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and is intended to include the scope indicated by the claims, and all modifications within the meaning and scope equivalent to the claims.

[0113] The number of the gripping pieces may be one or three or more. When the information recording code is a quadrilateral two-dimensional code, the shape of the information recording code may be a rectangle. The information recording code may also be a one-dimensional code such as a barcode.

[0114] A marking line for bending the holding piece may also be provided on the holding piece on which a portion of the information recording code is printed. The marking line may be formed to intersect the boundary between the holding piece and the cover body. In the manner in which the marking line is provided on the holding piece on which a portion of the information recording code is printed, the holding piece may be bent at the marking line in a mountain fold or a valley fold when the container is packaged with a transparent heat shrink film. Thus, when viewed from a code reader, a portion of the information recording code is further hidden or deformed. As a result, it becomes further difficult to read the information recording code, and as a result, it is possible to further prevent improper reading.

[0115] The cover body may also include, for example, a transparent film that covers the prescribed printing (printing of product name, etc.) and the printing of information recording code described in the above embodiment. The base material layer included in the cover body may also be, for example, a transparent plastic film, aluminum foil, etc. The above printing may also be performed on the inner surface side of the base material layer. The cover body is not limited to a paper cover body, and may also be a plastic cover body, for example.

[0116] The food contained in the container is not limited to ready-to-eat food.

[0117] The container may be partially wrapped with a heat shrink film. For example, the heat shrink film may be wrapped around the periphery of the cover and the end of the container body on the cover side. In this case, the holding piece can be bent by wrapping with the heat shrink film, so that the information recording code can be prevented from being improperly read as in the above embodiment.

[0118] The above-described embodiments and modifications may be appropriately combined without departing from the spirit and scope of the present invention.
