Description

FIELD OF THE INVENTION

[0001] The invention relates to packaging for a tobacco product.

State of the art

[0002] Tobacco products, such as cigarettes, are usually wrapped in packages for a given amount of tobacco products. A package formed from a sheet of inner wrapping paper, for example, paper coated with aluminum foil, and a sheet of outer wrapping paper covering a sheet of inner wrapping paper, is well known and is called a separate bundle. As a sheet of outer wrapping paper, a so-called soft bundle or soft packaging made of thin paper, or a so-called solid bundle, solid packaging or box, which is formed by forming cardboard into a box, is known.

[0003] Information about the tobacco product, such as the name of the tobacco product and the number of ingredients, is usually printed on the outer surface of the packaging for the tobacco product. Many packages have a design made up of letters, pictures, etc. information printed on the surface using color printing ink to enhance, for example, differences from another tobacco product or to motivate purchases, and have color effects.

SUMMARY OF THE INVENTION

Technical problem

[0005] As indicated above, many tobacco product packaging receive visual effects by adding a design using printing ink. The use of large amounts of paint can lead to an increase in manufacturing costs and to paint losses due to the adhesion of paint to the guides of the wrapping machine.

[0006] In view of the foregoing, an object of the present invention is to provide a packaging for a tobacco product on which a design can be added by simply constructing not based on the use of printing ink.

The solution of the problem

[0007] To solve the above problem, according to this invention, the packaging for the tobacco product is made so that the first zone, which is formed of a transparent varnish, and the second zone, which is formed of the open part of the base material of the package, where the base material of the package is open to the outside, or transparent lacquer applied to the outer surface of the base material, are adjacent to each other on the surface of the outermost layer in the packaging for the tobacco product and so that the position of the boundary between the first zone and the second zones minutes distinguishable on the basis of a difference in the presence or absence of a transparent lacquer or differences in the properties of transparent varnishes.

[0008] In particular, the present invention provides a package in which a tobacco product is placed inside, wherein the surface of the outermost layer of the package includes a first zone that is formed of a clear varnish applied to the outer surface of the base material of the package and a second zone that is located adjacent to the first zone and is formed from the open part of the base material, where the base material is open to the outside, or from a transparent varnish applied to the outer surface of the base material, and the position of the boundaries S between the first zone and the second zone is distinguishable on the basis of only the difference in the presence or absence of transparent varnish or the difference in the properties of transparent varnishes. The above construction allows you to add design packaging for a tobacco product without adding design using colored printing ink, but only by building and improving the visibility of the packaging. The position of the boundary between the first zone and the second zone can be distinguished only on the basis of the difference in a given property, which affects the visibility of transparent varnishes.

[0009] The clearcoat in the first zone may have a first gloss value, and the clearcoat in the second zone may have a second gloss value that is different from the first gloss value and allows the boundary position to be identified with the first zone due to a difference from the first gloss value. As indicated above, due to the difference in the gloss of the transparent varnishes forming the surfaces in the first zone and the second zone, it is possible for the user to identify the position of the boundary between the first zone and the second zone. It should be noted that in this case, the difference between the first gloss value and the second gloss value is preferably not less than 15, in order to enable the consumer to identify the position of the boundary between the first zone and the second zone.

[0010] The clearcoat in the first zone may have a first haze value, and the clearcoat in the second zone may have a second haze value, which is different from the first haze value and allows you to identify the position of the border with the first zone due to the difference from the first haze value. As indicated above, the choice of various values of haze of transparent varnishes forming surfaces in the first zone and in the second zone allows the consumer to identify the position of the boundary between the first zone and the second zone. It should be noted that in the event of a difference between the first haze value and the second haze value, preferably not less than 5% and not more than 100%, it makes it possible for the consumer to identify the position of the boundary between the first zone and the second zone.

[0011] The height of the surfaces in the first zone and in the second zone may be the same. The difference in surface height between the first zone and the second zone can be no more than 5 microns. Setting the difference in surface height between the first zone and the second zone of not less than 0 μm and not more than 5 μm, as mentioned above, creates the following effects. For example, the package is formed as a whole by folding the sheet blank. By eliminating or reducing the level difference between the first zone and the second zone, cumbersomeness during bending and distribution of the workpieces can be prevented. Thus, the distribution cost of the workpieces can be reduced by minimizing the gap between vertically stacked workpieces during placement of the workpieces in the workpiece box.

[0012] Many of the wrapping machines that wrap tobacco products during bending of the preform transport the preforms sequentially using a roller device and a suction device. Reducing the difference in level between the first zone and the second zone, as mentioned above, facilitates the stability of transportation of the workpiece during the wrapping process of the package and simplifies the stable bending of the workpiece at the folding stage. Reducing the difference in level between the first zone and the second zone also makes it possible to prevent the use of an excessive amount of transparent varnish on the base material in the first zone or second zone, which reduces the cost of packaging.

[0013] A colored zone that is colored can be formed on a part of the outer surface of the base material, and the boundary position between the first zone and the second zone and the boundary position between the colored zone and the non-colored zone around the colored zone in the base material can be shifted. This makes it possible to visually identify the position of the boundary between the first zone and the second zone only on the basis of differences in the presence or absence of transparent varnish between the first zone and the second zone or differences in the properties of transparent varnishes. Thus, the design can simply be added to the packaging for the tobacco product, without the use of printing ink.

[0014] The entire outer surface of the base material may not be painted. The above construction makes it possible to prevent contamination of the guides of the wrapping machines with printing ink, even, for example, in the case when the package comes into contact with the guides during the manufacture of the packages. Not using printing ink on the outer surface of the base material in the package can reduce the cost of packaging.

[0015] The outer surfaces of the parts corresponding to the first zone and the second zone of the base material can be painted with a single printing ink. According to this invention, the position of the boundary between the first zone and the second zone can not be identified on the basis of printing ink even when the outer surfaces of the parts corresponding to the first zone and the second zone are painted with a single printing ink, as indicated above.

[0016] The surface of the base material can be unevenly processed, and the position of the boundary between the first zone and the second zone and the position of the boundary between the recessed block and the protruding block in the base material can be shifted in plan view. The above construction makes it possible to visually identify the position of the boundary between the first zone and the second zone only on the basis of differences in the presence or absence of transparent varnish between the first zone and the second zone or differences in the properties of transparent varnishes. Thus, the design can simply be added to the packaging for the tobacco product without the use of printing ink.

[0017] It should be noted that the means for solving problems according to this invention can be combined, if possible.

Advantages of the Invention

[0018] This invention allows the creation of packaging for a tobacco product, to which design can be added using a simple construction that is not based on the use of printing ink.

Description of Embodiments

[0020] The following is a description of embodiments of the present invention with reference to the accompanying drawings. Unless otherwise indicated, the technical scope of the invention is not limited to dimensions, materials, shapes, relative location, etc. components indicated in the embodiments.

First embodiment

[0021] FIG. 1 is an external view of a package 1 according to a first embodiment. Package 1 is a cigarette package that houses cigarettes as an example of a tobacco product. The package 1 includes a block 2 of the main body and a block 4 of the cover, which is rotatably connected to the block 2 of the main body using the hinge 3. In FIG. 1, the package is shown in isometric view with the lid unit 4 closed in a view from the rear surface side. The package 1 has an approximately rectangular parallelepiped shape after wrapping the object to be wrapped. In FIG. 2, the package 1, according to the first embodiment, is shown in a front view.

[0022] The package 1 is a box-shaped packaging container called a solid pack and contains cigarettes inside the main body unit 2. Block 2 of the main body has a front wall 21, a rear wall 22, a pair of side walls 23 and a lower wall 24 and is a shell having a shape obtained by oblique cutting of the upper end side of a rectangular parallelepiped. The lid block 4 has a front wall 41, a rear wall 42, a pair of side walls 43 and an upper wall 44, and the lower edge of the rear wall 42 in the lid block 4 and the upper edge of the rear wall 22 in the main body block 2 are connected by a hinge 3.

[0023] FIG. 3 shows a blank 10 for forming a package 1 according to a first embodiment. The package 1 is formed by assembling the preform 10, which is obtained by stamping a paper material, such as cardboard or manila cardboard, with the given size and shape. The broken line in FIG. 3 shows a fold line (straight line). The package 1 is collected, for example, using a wrapping machine (not shown). The package 1 can be assembled by bending the preform 10 along the fold lines and connecting to each other in the right places. It should be noted that at 11 in FIG. 3, the formation zone of the block of the main body, which serves as the block 2 of the main body of the package 1 after the assembly of the workpiece 10, is indicated by 12; the zone of formation of the lid block, which serves as the block 4 of the lid of the packaging 1 after the assembly of the workpiece 10, is indicated.

[0024] The following is a description of the cross-sectional structure of package 1. In FIG. 4 shows a section along the line A-Aʹ in FIG. 2. In the embodiment shown in FIG. 2 example, the second zone R2, is formed in the form of a zone having a diamond shape, and the part that does not include the second zone R2, is formed in the form of the first zone R1. In other words, the first zone R1 is formed as a zone surrounding the second zones R2. It should be noted that the forms of the first zone R1 and the second zone R2 are not limited to specific forms and can be changed appropriately. For example, the shape of each first zone R1 and the second zone R2 can be a logo shape or a geometric pattern, such as the moon or the sun, or a decorative picture that has an animal, plant or the like as a motive. The first zone R1 or the second zone R2 may not be surrounded by another zone.

[0025] As shown in FIG. 4, the cross-sectional structure (layer structure) of the first zone R1 in the package 1 consists of a base material 50 as the innermost layer and a first lacquer layer 51 as the outermost layer. The first lacquer layer 51 is applied to the base material 50 so that the outer surface 50a of the base material 50 is coated with it. It should be noted that in this embodiment, the paper base material, such as cardboard or manila cardboard, which is used as the material for the blank 10, is selected as the base material 50. The base material 50 is not limited to the paper base material, and one of various materials, such as plastic and film laminate. The thickness of the base material 50 is not specifically limited.

[0026] The inner surface 50b of the base material 50 is a surface that faces the space for accommodating cigarettes after packaging 1. The ink layer is printed on which a design including a letter, shape or the like is printed using color printing ink or etc., is not formed on the base material 50 of the package 1, according to this embodiment. Thus, the design using color printing ink is not present on the package 1. In the first zone R1 of the package 1 having the above cross-sectional structure, the surface on the outermost layer of the package 1 is formed by the first lacquer layer 51.

[0027] In contrast, the cross-sectional structure of the second zone R2 in the package 1 consists of a base material 50 as the innermost layer, a first lacquer layer 51 as an intermediate layer and a second lacquer layer 52 as the outermost layer. The first lacquer layer 51 and the second lacquer layer 52 are deposited in this sequence on the outer surface 50a of the base material 50. In the second zone R2 of the package 1 having the above cross-sectional structure, the surface of the uppermost layer of the package 1 is formed by the second varnish layer 52.

[0028] The following is a description of the first varnish layer 51 and the second varnish layer 52. The first varnish layer 51 and the second varnish layer 52 are both formed from a transparent varnish. In the present invention, the transparent varnish for the first varnish layer 51 and the transparent varnish for the second varnish layer 52 are distinguished from each other by properties. In particular, transparent varnishes differ from each other in the amount of gloss. The term "transparent varnish" refers in this case to the so-called unpainted varnish and is defined as a varnish that does not contain pigment, dye, metal powder, glass powder and mica. It should be noted that, for example, a varnish containing a resin, which itself has a color, is considered as not painted in this description, if the varnish does not contain pigment, dye, metal powder, glass powder and mica. In this specification, a printing ink containing at least one pigment, a dye, a metal powder, a glass powder, and a mica is defined as a color printing ink. Although the first lacquer layer 51 and the second lacquer layer 52 are not particularly limited, transparent coating varnishes (hereinafter referred to as OP lacquers) can be used, which differ from each other in the amount of gloss. In the following description, a transparent varnish forming the first varnish layer 51 is called a first transparent varnish, and a transparent varnish forming a second varnish layer 52 is called a second transparent varnish. It should be noted that in this embodiment, the position of the boundary between the first zone R1 and the second zone R2 is made identifiable by selecting properties that affect the visibility, such as gloss value or haze value, of the transparent varnishes different in the first lacquer layer 51 and in the second lacquer layer 52, as will be explained below. A varnish to which an additive, such as a dulling agent is added, to change the amount of gloss or the dullness, also corresponds to a clear varnish if the varnish does not contain pigment, dye, metal powder, glass powder and mica.

[0029] The application of the first lacquer layer 51 and the second lacquer layer 52 to the base material 50 of the package 1 (blank 10) can be carried out using a known method, such as offset printing or intaglio printing. Since the first varnish layer 51 and the second varnish layer 52 are both made of transparent varnish, for example, the first transparent varnish forming the first varnish layer 51 can be first applied to the entire outer surface of the base material 50, and the second transparent varnish forming the second varnish layer 52 can then be applied using a plate with a design corresponding to the second lacquer layer 52 to the first lacquer layer 51.

[0030] As an example of a combination of the first lacquer layer 51 and the second lacquer layer 52, differing in the amount of gloss from each other, two types of transparent varnishes selected from matte varnish, normal varnish and glossy varnish can be provided. In this embodiment, the package 1 is designed so that the position of the boundary between the first zone R1 and the second zone R2, adjacent to each other in a plan view of the outer surface of the outer layer itself, is visually recognizable by using only differences in properties between the respective transparent varnishes in the first zone R1 and the second zone R2 (in this case, differences in the amount of gloss between the first zone R1 and the second zone R2). In the following description, the gloss value of the first lacquer layer 51 is called the first gloss value, while the gloss value of the second lacquer layer 52 is called the second gloss value. In this embodiment, the second gloss value of the second lacquer layer 52 is different from the first gloss value of the first lacquer layer 51 and is defined as the gloss value that identifies the position of the boundary between the first zone R1 and the second zone R2, due to the difference in gloss (difference in gloss value) from the first gloss values.

[0031] It should be noted that the expression "providing identification of the position of the boundary between the first zone R1 and the second zone R2" means that when considering the package 1 visual recognition of the position of the boundary between the first zone R1 and the second zone R2. As shown in FIG. 5 of the original example, after the formation of the area 53 of the printed ink, as the color zone in which the design is added by applying printing ink on the base material, the first varnish layer 51 and the second varnish layer 52 are successively applied to each other. It should be noted that the non-painted zone in which the outer surface 50a of the base material 50 is not painted, is formed around a colored printing ink of the zone 53. In the embodiment shown in FIG. 5 of the original example, the contour (outer form) of the second lacquer layer 52 coincides with the contour (outer form) of the printed ink portion 53 in a plan view (the contours coincide vertically). In other words, the position of the boundary between the first region R1 and the second region R2 and the position of the boundary between the ink printed portion 53 and the non-inked region around the ink portion 53 coincide with each other in a plan view (vertically overlapping each other), and the original example is an aspect in which the second lacquer layer 52 is in harmony with the design added by the ink portion 53. An aspect in which the second lacquer layer 52 is applied and disposed on the ink portion 53 is capable of it does not identify the boundary position between the first zone R1 and the second zone R2, and does not allow to identify the boundary position between the first zone R1 and the second zone R2 only on the basis of the difference in properties between the first lacquer layer 51 and the second lacquer layer 52. Thus, package 1 differs from that shown in FIG. 5 of the original example by the fact that the package 1 allows the boundary position between the first zone R1 and the second zone R2 to be identified only due to the difference in properties between the first lacquer layer 51 and the second lacquer layer 52.

[0032] The tobacco product package 1, according to this embodiment, enables visual identification of the boundary position between the first zone R1 and the second zone R2 not based on color printing ink, as indicated above, but based on only differences in properties between the first lacquer layer 51 and the second lacquer layer 52, or, in particular, differences in the amount of gloss. Thus, it is possible to add a design to packaging 1 for a tobacco product, without adding a design based on the use of color printing ink, and using only a simple construction to increase the recognition of packaging 1.

[0033] Since the tobacco products are wrapped at a high speed by the wrapping machine, the gap between the guides of the wrapping machine and the workpiece 10 serving as a package is relatively small. Therefore, there is a likelihood of the packaging coming into contact with the guides in the process of wrapping tobacco products. If in order to obtain visual effects, the conventional method uses printing ink to add design, then printing ink may contaminate the guides of the wrapping machine. In contrast, in package 1, according to this embodiment, the entire outer surface of the base material 50 of package 1 is not painted. With this construction, when the guides of the wrapping machine for making the package 1 comes into contact with the workpiece 10 during bending of the workpiece 10 with the help of the wrapping machine, the contact does not cause a risk of contamination with printing ink, i.e. adhesion of color printing ink to the guides. In addition, the absence of the use of color printing ink can reduce the cost of manufacturing packaging 1.

[0034] It should be noted that the aspect in which the first lacquer layer 51 is made in the form of a layer underlying the second lacquer layer 52 in the second zone R2 by forming the first lacquer layer 52 on the entire base material 50 for packaging 1, was given as an example in this embodiment. As shown in the modification of FIG. 6, the first varnish layer 51 in the second zone R2 may not be present, and the second varnish layer 52 may be applied directly to the base material 50. In FIG. 6 shows a cross-sectional structure of a package according to a first modification. Thus, the surface of the outermost layer in the package 1 includes a first zone R1 and a second zone R2, which are adjacent to each other, and the second gloss value of the second transparent varnish in the second zone R2 can be selected as the gloss value, which makes it possible to identify the position the boundary between the first zone R1 and the second zone R2 due to the difference in gloss from the first gloss value of the first transparent varnish in the first zone R1. In FIG. 7 shows a cross-sectional structure of a package according to a second modification. As shown in FIG. 7, the end portions of the first lacquer layer 51 and the second lacquer layer 52 can be stacked vertically on top of each other at the boundary portion between the first zone R1 and the second zone R2. R3 in FIG. 7, an overlay zone is defined which is formed by superimposing on each other the first lacquer layer 51 and the second lacquer layer 52. The width of the overlay zone R3 is not particularly limited in FIG. 7. For example, as an example, the width is from about 0.05 mm to 1 mm. As shown in FIG. 7, the location of the overlay zone R3, in which transparent varnishes differing in gloss value from one another, are applied to each other, in the boundary part between the first zone R1 and the second zone R2 makes the difference in gloss value between the first zone R1 and the second zone R2 more significant , which allows easier identification of the position of the boundary between the zones. It should be noted that although a second lacquer layer 52 is applied to the first lacquer layer 51 in the overlay zone R3 in the one shown in FIG. 7 example, the first varnish layer 51 can be applied to the second varnish layer 52.

[0035] FIG. 8 is a front view of a package according to a third modification of an embodiment. The modification shown in FIG. 8 is an aspect in which the first zone R1 or the second zone R2 on the outermost layer of the package 1 (blank 10) is not surrounded by another zone. As indicated above, the first zone R1 and the second zone R2 may be adjacent to each other, and one of the zones may not be surrounded by another zone.

Examples

[0036] The following is a more specific description of the present invention using examples. The invention is not limited to the following description of examples, if the invention does not depart from the idea of the invention.

Examples 1-3

[0037] Samples were prepared by applying commercially available clearcoats to commercially available sheets of paper with a white backing (such as sheets of wood-free paper having a whiteness of 80 to 90% used in Examples 1-3). A 60 ° reflective gloss value was measured using a commercially available portable gloss meter.

[0038] It should be noted that the varnish usually contains a resin component, a solvent, an additive, and the like. Types of varnishes include oil based varnish, water based varnish and UV varnish. Examples of the resin component contained in the oil-based varnish include soluble nitrocellulose and ketone resins. Examples of the solvent include ethyl nitrate and IPA (isopropyl alcohol). Examples of the additive include waxes and dulling additives (and optionally, antifoam agents). Examples of the resin component contained in the water-based varnish include ethanol, IPA and water. Examples of the additive include waxes and dulling additives (and optionally, antifoam agents). Examples of the resin component contained in the UV varnish include acrylate monomers / oligomers and acrylic resins. Examples of the solvent include ethyl acetate and IPA. Examples of the additive include waxes and dulling additives (and optionally, antifoam agents). It should be noted that of the above ingredients, soluble nitrocelluloses are associated in most cases with the heat resistance of the varnish, ketone resin is associated with the gloss of the varnish, water-based acrylic resin is associated with the gloss and heat resistance of the varnish, acrylate monomers / oligomers are associated with the gloss and heat resistance of the varnish acrylic resin is associated with the transparency and stickiness of the varnish, wax is associated with abrasion resistance and slippery of the varnish, and the dulling additive is associated with the gloss of the varnish.

[0039] Applying appropriate clearcoats to the base paper sheets is carried out using a commercially available automatic intaglio desktop printing device and a hard plate (Helio 175 lines per inch). During printing of each transparent varnish, the varnish was dissolved using a solvent in a 7: 3 ratio between IPA and water and adjusted so that the number of seconds when measuring viscosity using a Tsan cup (viscosity measuring cup) No. 3 was 16 seconds. As for the clearcoats to be applied to the base paper, normal clearcoat was used in example 1, glossy clearcoat was used in example 2, and matte clearcoat was used in example 3.

[0040] It should be noted that the gloss value in Example 2 (using a glossy transparent varnish) was selected so that it was larger (higher) than the gloss value in Example 1 (using a normal transparent varnish) as the initial value, and that the gloss value in Example 3 (using a matte clearcoat) is less (lower) than the gloss value in Example 1 (using a normal clearcoat). The gloss value can be adjusted, for example, by changing the mixing ratio between the resin component and the dulling additive contained in the varnish. For example, the varnish gloss value can be increased by increasing the mixing ratio of the resin component contained in the varnish. For example, the gloss of the varnish can be reduced by increasing the mixing ratio of the dulling additive contained in the varnish.

Examples 4-6

[0041] Examples 4-6 are similar to examples 1-3 except that sheets of blue base paper (obtained by continuously applying cyan (cyan) printing ink on the entire surface of sheets of wood-free paper having a whiteness of 80, were used as base paper sheets) -90% used in examples 1-3), on which transparent varnishes were applied, instead of sheets of white base paper.

Gloss Measurement

[0042] Table 1 shows the result of measuring 60 ° of the reflective gloss value of each sample using a portable gloss meter (the micro-TRI-gloss μ) from Toyo Seiki Seisaku-sho, Ltd) in Examples 1-6. For each sample, gloss values were measured at 5 points of the sample, and the average gloss value is shown in Table 1.

[0043] Table 1

Sensory assessment

[0044] Samples according to examples 1-3 were arranged adjacent to each other, and a sensory assessment was made regarding the difference in appearance of the transparent varnishes of the samples. As a result of comparison between the sample (normal transparent varnish) from Example 1 and the sample (glossy transparent varnish) from Example 2, the difference value (average value) of the gloss value, which was 18.0, was measured, and the difference in the appearance of the two transparent varnishes was detected. As a result of the comparison between the sample (normal transparent varnish) from Example 1 and the sample (matte transparent varnish) from Example 3, the difference value (average value) of the gloss value was 25.7, and a more noticeable difference in the appearance of the transparent varnishes was noted. than when comparing between examples 1 and 2.

[0045] Similarly, a sensory assessment was performed regarding the difference in appearance of the transparent varnishes of the respective samples from Examples 4-6, as in Examples 1-3. As a result of comparison between the sample (normal transparent varnish) from Example 4 and the sample (glossy transparent varnish) from Example 5, the difference value (average value) of the gloss value, which was 17.3, was measured, and the difference in the appearance of the two transparent varnishes was detected. As a result of comparison between the sample (normal transparent varnish) from Example 4 and the sample (matte transparent varnish) from Example 6, the difference value (average value) of the gloss value, which was 35.8, was measured, and a more noticeable difference in the appearance of the transparent varnishes was noted. than when comparing between examples 4 and 5 and when comparing between examples 1 and 3.

[0046] From the above it follows that in package 1 the difference between the gloss value of the first lacquer layer 51, which forms the outermost layer of the first zone R1, and the gloss value of the second lacquer layer 52, which forms the outermost layer in the second zone R2, is preferably not less than 15, more preferably not less than 25, and particularly preferably not less than 35. The choice of such a difference between the gloss value of the first lacquer layer 51 and the gloss value of the second lacquer layer 52 allows the packaging 1 to be visually recognized ( identify) the position of the boundary between the first zone R1 and the second zone R2 only by means of a difference in properties between the first lacquer layer 51 and the second lacquer layer 52, without adding a design using color printing ink. It should be noted that the difference in gloss between the first varnish layer 51 and the second varnish layer 52 should preferably be large in terms of providing a greater difference in the appearance of the first and second varnish layers 51 and 52, and an upper limit for the difference in gloss between the first varnish layer 51 and the second lacquer layer 52 is not specifically limited. In the case of using paper base material, an aspect in which the difference in gloss between the first lacquer layer 51 and the second lacquer layer 52 is not more than 100, is given as an example. It should be noted that the preferred upper limits for the difference in gloss between the first lacquer layer 51 and the second lacquer layer 52 may vary depending on the type of base material.

[0047] The package 1, according to this embodiment, is configured such that the position of the boundary between the first zone R1 and the second zone R2 is identifiable only on the basis of a difference in a predetermined property that affects the visibility of the first lacquer layer 51 forming the outermost layer in the first zone R1, and a second lacquer layer 52, forming the outermost layer in the second zone R2. The present invention is not limited to the amount of gloss if the above position of the border is identifiable only by a difference in the property of the transparent varnishes. For example, the haze values of the respective transparent varnishes forming the outermost layers in the first zone R1 and in the second zone R2 can be chosen different to identify the position of the boundary between the first zone R1 and the second zone R2. It should be noted that the concept of haze value (in Japanese heizuchi) can refer in Japan to both hezuchi and kumorido. The haze value of a transparent varnish is an example of a given property that affects visibility, like a gloss value. In this invention, the position of the boundary between the first zone R1 and the second zone R2 can be identified based on the difference in the haze of the transparent varnishes. Such an aspect also falls into the category of aspects in which the boundary position between the first zone R1 and the second zone R2 is identified only by a difference in properties between the first lacquer layer 51 and the second lacquer layer 52.

[0048] Transparent varnishes, differing in matte color, are typically glossy. Also in this embodiment, the first varnish layer 51 (first transparent varnish) and the second varnish layer 52 (second transparent varnish) differ from each other both in terms of gloss and dullness. The haze values of the first varnish layer 51 (first transparent varnish) and the second varnish layer 52 (second transparent varnish) are called the first haze value and the second haze value, respectively. In this embodiment, the second haze value is selected as the haze value, which makes it possible to identify the position of the boundary between the first zone R1 and the second zone R2 using a difference from the first haze value. In the package, according to this embodiment, the identification of the boundary position between the first zone R1 and the second zone R2 can only be based on the difference in gloss between the first varnish layer 51 and the second varnish layer 52, can only be based on the difference in the amount of haze, or can be based on on the difference in the value of gloss, and on the difference in the value of haze.

[0049] In this embodiment, the haze value of the first transparent varnish used for the first varnish layer 51 and the second transparent varnish used for the second varnish layer 52 are properties representing the transparency of the first transparent varnish and the second transparent varnish, and a lower value means higher transparency. The haze value can be measured by preparing samples obtained by applying the first clearcoat and the second clearcoat to the transparent films and calculating the ratio of the scattered light to the total transmitted light (haze value = scattered light / total transmitted light · 100 (%)) when each sample irradiated with a light beam in accordance with JIS K 7105 and JIS K 7136. Using this method, the corresponding haze values of the first clear coat and the second clear coat can be measured.

[0050] It should be noted that the difference between the amount of haze (hereinafter referred to as the first haze value) of the first transparent varnish forming the first varnish layer 51 in the first zone R1 and the haze value (referred to as the subsequent second haze value) of the second transparent varnish forming the second the lacquer layer 52 in the second zone R2, preferably not less than 5% and not more than 100%. Setting the difference between the first haze value and the second haze value within the above range allows the consumer to simply identify the position of the boundary between the first zone R1 and the second zone R2 based on the difference between the first haze value and the second haze value.

Second embodiment

[0051] The following describes a package 1A according to a second embodiment. In FIG. 9 is a front view of a package 1A according to a second embodiment. At 53A in FIG. 9 denotes the colored ink portion that is provided on the packaging 1A. The ink-colored portion 53A is formed by applying color printing ink to the outer surface 50a of the base material 50, and the ink-dyed ink 53A alone adds design to the package 1A. The first zone R1 and the second zone R2 shown in FIG. 9 are made in accordance with the description of FIG. 4. It should be noted that the first lacquer layer 51 and the second lacquer layer 52 are successively applied to the outer surface of the base material on which the ink-colored portion 53A is formed. It should be noted that, as shown in FIG. 9, the ink-dyed portion 53A is formed on a portion of the outer surface 50a of the base material and corresponds to the ink zone in the present invention.

[0052] As shown in FIG. 9, this embodiment has an aspect in which the position of the boundary between the first zone R1 and the second zone R2 is shifted from the position of the boundary between the outline (outer shape) of the printed ink portion 53A, i.e. between the ink printed portion 53A and the non-inked area present around the ink printed portion 53A. In addition, the first zone R1 does not vertically overlap the portion 53A printed by the ink. Packaging 1A with the above construction allows the consumer to identify the position of the boundary between the first zone R1 and the second zone R2 not on the basis of the ink-printed part 53A, as indicated above, but on the basis of only differences between properties (specified properties that affect visibility), such as the gloss value or haze value of the first lacquer layer 51 in the first zone R1 and the second lacquer layer 52 in the second zone R2, the first lacquer layer 51 and the second lacquer layer 52.

Third Embodiment

[0053] FIG. 10 is a front view of a package 1B according to a third embodiment. Package 1B includes a printed ink portion 53B similar to the ink printed portion 53A of packaging 1A, according to a second embodiment. The package 1B differs from the package 1A according to the second embodiment in that the first zone R1 and the inked part 53B partially overlap. Thus, the above aspect is an aspect in which the position of the boundary between the first zone R1 and the second zone R2 is shifted from the position of the boundary between the outline (outer shape) of the printed ink portion 53B, i.e. the ink-printed portion 53B and the non-inked area around the ink-printed portion 53B. This allows the consumer to identify the position of the boundary between the first zone R1 and the second zone R2 not on the basis of the printed ink portion 53B indicated above, but on the basis of only differences between properties (specified properties that affect visibility), such as gloss or haze values the second lacquer layer 51 and the second lacquer layer 52, the first lacquer layer 51 and the second lacquer layer 52. Thus, the identification of package 1B can be improved by adding design to package 1B in the middle It is easy to build, without adding design using printing ink.

Fourth Embodiment

[0054] FIG. 11 is a front view of a package 1C according to a fourth embodiment. In the previous indicated embodiments, the first lacquer layer 51 is coated continuous with the coating of the entire base material 50. In the package 1C, the first lacquer layer 51 is not formed. In FIG. 12 shows a section along line A-Aʹ in FIG. 11. A description of the cross-sectional structure of the first zone R1ʹ and the second zone R2ʹ of the package 1C according to the fourth embodiment is given below with reference to FIG. 12. The first zone R1ʹ in package 1C is the zone in which the outer surface 50a of the base material 50 is open to the outside and corresponds to the open portion of the base material in this invention. In the second zone R2ʹ in the package 1C, a transparent varnish layer 52 is formed by applying a transparent varnish to the outer surface 50a of the base material 50. The transparent varnish layer 52 forms the outermost layer in the second zone R2ʹ in the package 1C.

[0055] Examples of the clearcoat forming the clearcoat layer 52 include a matte varnish, a normal varnish and a glossy varnish that are free of pigment, dye, metal powder, glass powder and mica and are transparent. The gloss value of the transparent varnish layer 52 differs from the gloss value of the open part of the base material in the first zone R1ʹ and is set as the gloss value, which allows us to identify the position of the boundary between the first zone R1ʹ and the second zone R2ʹ using the difference from the gloss value of the open part of the base material. Thus, the package 1C, according to this embodiment, is constructed so that the boundary position between the first zone R1 R and the second zone R2ʹ is identified only by the presence or absence of a transparent varnish (a transparent varnish is not formed on the outer surface of the base material corresponding to the first zone R1ʹ, and transparent varnish is formed only on the outer surface of the base material corresponding to the second zone R2ʹ). In this embodiment, the gloss value of the open part of the base material forming the outermost layer in the first zone R1ʹ corresponds to the first gloss value, while the gloss value of the transparent varnish layer 52 forming the outermost layer in the second zone R2ʹ corresponds to the second gloss value. In this embodiment, the difference in gloss between the transparent varnish layer 52 and the open part of the base material is preferably not less than 15 in order to provide visual recognition (identification) of the boundary position between the first zone R1ʹ and the second zone R2ʹ due to the difference in gloss between the transparent varnish layer 52 and the open part of the base material, more preferably not less than 25 and particularly preferably not less than 35. This construction allows the consumer to identify the position of the boundary between the first zone R1ʹ and W the second zone R2ʹ, which form the surface of the outermost packing layer 1C, only due to the difference in the presence or absence of transparent varnish between the first zone R1ʹ and the second zone R2ʹ. In other words, the 1C package allows you to identify the position of the boundary between the first zone R1ʹ and the second zone R2ʹ only due to the difference in gloss between the transparent varnish layer 52 and the open part of the base material in the 1C package in the first zone R1ʹ and in the second zone R2ʹ. As a result, a design can be added to 1C packaging using simple construction without adding a design using color printing ink.

Fifth Embodiment

[0056] FIG. 13 is a front view of a package 1D according to a fifth embodiment. The 1D package differs from the packages according to the previous embodiments in that the base material 50 is unevenly processed. At 60 in FIG. 13, the protruding block obtained by convexly lifting the base material of the packaging 1D outward by means of embossing is indicated. The package 1D is designed so that the part that does not include the protruding block 60 is made in the form of a recessed block relative to the protruding block 60. The 1D package, according to this embodiment, is the same as the package obtained by replacing the printed ink portion 53B in the package 1B, according to the third embodiment protruding block 60. As shown in FIG. 13, in the package 1D, the second zone R2 and the protruding block 60 partially overlap. Thus, the above aspect is an aspect in which the boundary position between the first region R1 and the second zone R2 is shifted from the boundary position between the contour (outer line) of the protruding block 60, i.e. the protruding block 60 and the non-colored area around the protruding block 60. This allows the consumer to identify the position of the boundary between the first zone R1 and the second zone R2 not on the basis of the protruding block 60 above, but only on the basis of the difference between the properties (specified properties that affect visibility), such as gloss or haze values of the first lacquer layer 51 and the second lacquer layer 52, the first lacquer layer 51 and the second lacquer layer 52. It should be noted that the protruding block 60 may be located dix so that the protruding portion 60 does not overlap with a first region R1, or one of the second area R2, and so that the projecting unit is overlapped with the entire or part of another first region R1 and second region R2.

[0057] Various changes or improvements to the above embodiments are possible or combinations of embodiments are possible. For example, although each embodiment relates to solid packaging for cigarettes, the present invention is not limited to this. For example, the present invention can be applied to a sheet of outer packaging paper of so-called soft packaging instead of hard packaging. Separate packaging, such as hard packaging or soft packaging, is typically in use in a sealed film state. Individual packages are often in a state where several (e.g. 10) individual packages mentioned above are jointly packaged in an intermediate package called a unit. In this specification, film material by which a separate package is sealed with tobacco products placed therein, such as a solid package or a soft package, or an intermediate packaging box in which several individual packages are packed, such as a unit, also corresponds to a package for a tobacco product. Therefore, the present invention can be applied to film material for sealing a single package or an intermediate package for several individual packages, such as a unit. A cigarette is indicated as an example of a tobacco product in each of the above embodiments. However, the present invention can be applied, for example, to packaging that wraps a cigar, electronic cigarette or the like.
