Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the decorative sheet described in Patent Document 1, a three-dimensional effect is obtained due to the difference in reflectance and the height difference between the matte area and the gloss area, but there is a demand for further emphasizing the three-dimensional effect on the sheet surface.

[0005] Therefore, an object of the present invention is to provide a decorative sheet and a method for manufacturing the decorative sheet that can enhance the three-dimensional effect on the sheet surface and improve the decorativeness.

Means for Solving the Problems

[0006] A decorative sheet according to one aspect of the present invention is a decorative sheet having a printed and embossed surface, comprising a matte region having a matte layer with a rough texture on the sheet surface, and a glossy region having a glossy layer with a smooth texture on the sheet surface, wherein a groove is formed inside the glossy region along the outer edge of the glossy region. [Effects of the Invention]

[0007] According to the present invention, a three-dimensional pattern is applied to the sheet surface using a pseudo-embossing technique based on the difference in reflectivity between matte and glossy areas. Furthermore, by forming edge grooves in the glossy areas, reflection is strengthened at both edges where deformation is greater. As a result, the boundary between the matte and glossy areas becomes clearer due to the step and reflection of the edge grooves, further emphasizing the three-dimensional effect of the sheet surface and improving the decorative appeal of the decorative sheet. [Brief explanation of the drawing]

[0008] [Figure 1] This is a perspective view of the packaging box of this embodiment. [Figure 2] This is a partial cross-sectional view of the decorative sheet of the comparative example. [Figure 3] This is a plan view of the decorative sheet according to this embodiment. [Figure 4] Figure 3 is a partial cross-sectional view of the decorative sheet. [Figure 5] This figure shows an example of the printing process according to this embodiment. [Figure 6] This figure shows an example of embossing according to this embodiment. [Modes for carrying out the invention]

[0009] This embodiment will be described below with reference to the drawings. The arrows Fr, Rr, L, R, U, and Lo in each figure indicate the front, rear, left, right, top, and bottom sides, respectively. In this embodiment, terms indicating direction and position are used, but these terms are used for the convenience of explanation and do not limit the technical scope of the present invention. Figure 1 is a perspective view of the packaging box of this embodiment.

[0010] As shown in Figure 1, the top box (lid) of the packaging box 1 is formed by assembling a decorative sheet 5 (see Figure 3) which has printing and embossing applied to its surface. The sheet surface has matte areas 21 and glossy areas 22 formed by printing. The matte areas 21 have a matte layer with a rough texture, and the glossy areas 22 have a glossy layer with a smooth texture. The difference in reflectivity between these matte and glossy layers creates a pseudo-embossed effect on the sheet surface. On one side of the diagonally divided top surface of the packaging box 1, a grid pattern is formed by alternating diamond-shaped matte areas 21 and glossy areas 22.

[0011] Furthermore, the pseudo-embossed grid pattern has steps created by the embossing process. The glossy area 22 bulges upward from the matte area 21, and the glossy area 22 is higher than the matte area 21, creating a three-dimensional grid pattern on the packaging box 1. In addition to the pseudo-embossing created by the difference in reflectivity between the matte area 21 and the glossy area 22, the difference in height between the matte area 21 and the glossy area 22 further emphasizes the three-dimensionality of the surface of the packaging box 1, improving its decorative appeal. These irregularities between the matte area 21 and the glossy area 22 are formed on the sheet surface of the packaging box 1 before assembly using an embossing die.

[0012] As shown in the comparative example in Figure 2(A), in general embossing, an embossing die 51 consisting of a support plate 52 and a pressing plate 55 is used. A sheet material 58 with a pseudo-emboss formed on it is supported by the support plate 52, and the pressing plate 55 is positioned above the sheet material 58. The surface of the support plate 52 has a convex surface 53 corresponding to the glossy area 59 and a concave surface 54 corresponding to the matte area 61. The surface of the pressing plate 55 has a concave surface 57 opposite to the glossy area 59 and a convex surface 56 corresponding to the matte area 61. The sheet material 58 is sandwiched between the support plate 52 and the pressing plate 55, causing the glossy area 59 to bulge out more than the matte area 61.

[0013] As shown in Figure 2(B), in the embossing process using the embossing die 51 described above, the slope of the glossy region 59 rises gently from the outer edge of the matte region 61. In this case, reflection is stronger at the shoulder portion 62 where the deformation of the glossy region 59 is large, but reflection is weaker at the boundary between the matte region 61 and the glossy region 59. As a result, the boundary between the matte region 61 and the glossy region 59 becomes unclear, and the sense of three-dimensionality is suppressed. Therefore, in this embodiment, by providing an edge groove 24 inside the glossy region 22 along the outer edge of the glossy region 22, the reflection at both edges of the edge groove 24 is strengthened, clarifying the boundary between the matte region 21 and the glossy region 22 and further emphasizing the sense of three-dimensionality (see Figure 4).

[0014] The decorative sheet of this embodiment will be described with reference to Figures 3 and 4. Figure 3 is a plan view of the decorative sheet of this embodiment. Figure 4 is a partial cross-sectional view of the decorative sheet of Figure 3. In Figure 3, the areas with dot hatching are the matte layer, and the areas without dot hatching are the glossy layer. Furthermore, Figure 4(A) is a cross-section of the decorative sheet cut along line AA, Figure 4(B) is a cross-section of the decorative sheet cut along line BB, and Figure 4(C) is a cross-section of the decorative sheet cut along line CC.

[0015] As shown in Figure 3, the decorative sheet 5 is shown in the unfolded state of the top box of the packaging box 1 and is formed by cutting out a single sheet of corrugated cardboard. Coated cardboard is used as the outer liner of the decorative sheet 5, and it is a double-sided corrugated cardboard sheet with a single-sided corrugated cardboard sheet attached to the coated cardboard. In the following description, the direction in which the corrugation peaks of the core of the corrugated cardboard sheet extend will be referred to as the "corrugation direction X," and the direction perpendicular to the core of the corrugated cardboard sheet will be referred to as the "flow direction Y." In Figure 3, the corrugation direction X and flow direction Y of the decorative sheet 5 are aligned with the front-to-back and left-to-right directions, respectively.

[0016] In the center of the decorative sheet 5, an upper wall 11 is provided. On one side of the upper wall 11 in the stepped direction X, a rear wall 12 is connected via a broken line L1, and on the other side of the upper wall 11 in the stepped direction X, a front wall 13 is connected via a broken line L2. On one side of the upper wall 11 in the flow direction Y, one side wall 14 is connected via a broken line L3, and on the other side of the upper wall 11 in the flow direction Y, the other side wall 15 is connected via a broken line L4. On the outer side of the rear wall 12 in the flow direction Y, a pair of flaps 16 are connected via broken lines L5 and L6, and on the outer side of the front wall 13 in the flow direction Y, a pair of flaps 17 are connected via broken lines L7 and L8. The front wall 13 and one side wall 14 are provided with a wavy design cut.

[0017] On the half part of the upper wall 11 of the decorative sheet 5, a lattice pattern is formed by a diamond-shaped mat area 21 and a gloss area 22. As described above, the mat area 21 is provided with a mat layer having a rough texture and a low reflectivity, and the gloss area 22 is provided with a gloss layer having a smooth texture and a high reflectivity. The alternation of the mat area 21 and the gloss area 22 on the sheet surface improves the decorativeness of the decorative sheet 5. Also, the inner part of the gloss area 22, which will be described later, inside the edge groove 24 is formed higher than the mat area 21. Thus, the three-dimensional effect of the sheet surface is emphasized by the difference in reflectivity and the height difference between the mat area 21 and the gloss area 22.

[0018] In the decorative sheet 5, an edge groove 24 is formed inside the gloss area 22 along the outer edge of the gloss area 22. The edge groove 24 is formed by being pushed into a pressing blade of an embossing die to be described later, and the boundary between the gloss area 22 and the mat area 21 is made prominent by the edge groove 24. In the gloss area 22, the reflection is enhanced in the part with a large deformation, but in the edge groove 24, the reflection near the outer edge of the gloss area 22 is strengthened and the three-dimensional effect is emphasized. The front wall 13 and one side wall 14 are provided with a wavy pattern by the gloss area 22 and the mat area 21, and an edge groove 24 is also formed along the outer edge of the gloss area 22 inside the wavy gloss area 22.

[0019] In this case, the separation distance from the outer edge of the gloss area 22 to the edge groove 24 is designed to be larger than the dimensional tolerance. For example, at the position cut along the line B-B, in this embodiment, the separation distance from the outer edge of the gloss area 22 to the center line of the edge groove 24 is set to 1.0 [mm] (see Fig. 4(B)). Thereby, even if a slight deviation occurs at the outer edge of the gloss area 22 or the position of the edge groove 24 during the manufacture of the decorative sheet 5, the edge groove 24 does not protrude outside from the outer edge of the gloss area 22. Note that the separation distance from the outer edge of the gloss area 22 to the edge groove 24 can be appropriately changed according to the type (dimensional tolerance) of the decorative sheet 5.

[0020] A mat layer is provided over the remaining half of the upper wall 11 of the decorative sheet 5 and most of the rear wall 12 and the other side wall 15. In the mat layer, a linear gloss area 23 is formed in which linear gloss layers are provided along the broken lines L1, L4, and L6. The broken lines L1, L4, and L6 are provided inside the linear gloss area 23, and the folding portions are emphasized by the linear gloss area 23, improving the decorativeness of the packaging box 1. Since the mat layer is thicker than the gloss layer, by providing the broken lines L1, L4, and L6 in the thin gloss layer, the gloss layer (linear gloss area 23) is less likely to crack even when the decorative sheet 5 is folded along the broken lines L1, L4, and L6.

[0021] As shown in Fig. 4(A), at the cutting position along the line A-A, a height difference is provided between the mat area 21 and the gloss area 22, and the edge groove 24 is positioned near the boundary 29 between the mat area 21 and the gloss area 22. As shown in Fig. 4(B), at the cross-sectional position along the line B-B, a height difference is provided between the mat area 21 and the gloss area 22, and the edge groove 24 is positioned at a location that enters the gloss area 22 side from the boundary 29 between the mat area 21 and the gloss area 22. Thus, in a cross-sectional view of the decorative sheet 5 cut along the arrangement direction of the mat area 21 and the gloss area 22, the distance from the boundary 29 between the mat area 21 and the gloss area 22 to the edge groove 24 is larger on the other side (upper left side) than on one side (lower right side) in the arrangement direction.

[0022] As a result, at the cross-sectional position of line AA, reflection is strengthened near the boundary 29 between the matte region 21 and the glossy region 22, and at the cross-sectional position of line BB, reflection is strengthened in areas that extend beyond the boundary 29 between the matte region 21 and the glossy region 22 towards the glossy region 22. The decorative properties of the decorative sheet 5 are improved by giving regularity to the areas where the reflection of the alternating patterns is emphasized. Also, as shown in Figure 4(C), at the cross-sectional position of line CC, there is no difference in height between the matte region 21 and the linear glossy region 23, and the edge groove 24 is positioned inside the linear glossy region 23. In this case, the edge groove 24 may be located in the center of the linear glossy region 23, or it may be shifted to one side of the linear glossy region 23.

[0023] The manufacturing method of the decorative sheet according to this embodiment will be described with reference to Figures 5 and 6. Figure 5 shows an example of the printing process according to this embodiment. Figure 6 shows an example of the embossing process according to this embodiment. Figure 5(A) shows the printing process for the repellent varnish, Figure 5(B) shows the printing process for the glossy varnish, and Figure 5(C) shows the drying process. Also, Figure 6(A) shows the sheet material installation process, Figure 6(B) shows the sheet material die-cutting process, and Figure 6(C) shows the completed decorative sheet. The explanation of the sheet lamination process of coated cardboard and single-sided corrugated cardboard sheets will be omitted.

[0024] As shown in Figure 5(A), a repellent varnish 32 is printed on the surface of the coated cardboard 31 according to the color-printed grid pattern. In this case, the repellent varnish 32 is applied to the areas of the grid pattern that will become the matte layer, and not to the areas that will become the glossy layer. As shown in Figure 5(B), a glossy varnish 33 is printed on the surface of the coated cardboard 31 after the repellent varnish 32 has been printed. In this case, the glossy varnish 33 is applied to the entire coated cardboard 31. The glossy varnish 33 is repelled on the repellent varnish 32, creating fine irregularities, while the glossy varnish 33 is smooth in areas other than the repellent varnish 32.

[0025] As shown in Figure 5(C), the coated cardboard 31 is dried after printing with gloss varnish 33. In this case, ultraviolet light is irradiated onto the coated cardboard 31 to harden the repellent varnish 32 and gloss varnish 33. A matte layer 34 is formed when the gloss varnish 33 hardens while being repelled by the repellent varnish 32, and a glossy layer 35 is formed when the gloss varnish 33 hardens in areas other than the repellent varnish 32. On the surface of the coated cardboard 31, a matte region 21 with the matte layer 34 and a glossy region 22 with the glossy layer 35 are formed. A pseudo-emboss is formed on the coated cardboard 31 by the matte region 21 and the glossy region 22.

[0026] As shown in Figure 6(A), a sheet material 37, formed by laminating coated cardboard 31 and a single-sided corrugated cardboard sheet 36, is placed in the embossing die 41. The embossing die 41 includes a support plate 42 that supports the sheet material 37 and a pressing plate 45 located above the sheet material 37. The base plate 43 of the support plate 42 is formed in a flat shape from stainless steel. A CAD panel (convex portion) 44 is installed on the surface of the base plate 43 corresponding to the glossy area 22, and the base plate 43 is formed in an uneven shape by the surface of the base plate 43 and the surface of the CAD panel 44. The CAD panel 44 is formed smaller than the glossy area 22.

[0027] The base plate 46 of the pressing plate 45 is made of wooden plywood. Multiple pressing blades 47 made of stainless steel are installed on the underside of the base plate 46, forming a linear shape in plan view. The pressing blades 47 extend along the outer edge of the glossy area 22 and are positioned slightly inward from the outer edge of the glossy area 22. More specifically, the pressing blades 47 are positioned between the side of the CAD panel 44 and the outer edge of the glossy area 22. In addition, a cushioning material 48, such as cork, is installed on the underside of the base plate 46, corresponding to the matte area 21. The tips of the pressing blades 47 protrude below the underside of the cushioning material 48, and these tips of the pressing blades 47 are chamfered in an R shape.

[0028] As shown in Figure 6(B), the support plate 42 and the pressing plate 45 approach each other, and the pressing plate 45 presses against the sheet material 37 on the support plate 42. The sheet material 37 is sandwiched between the support plate 42 and the pressing plate 45, causing the sheet material 37 to deform to conform to the opposing surfaces of the support plate 42 and the pressing plate 45. At this time, the glossy layer 35 is pushed up by the CAD surface plate 44, forming a glossy region 22 that is higher than the matte region 21, and the matte layer 34 is pressed down by the cushioning material 48, forming a matte region 21 that is lower than the glossy region 22. The increase in the glossy region 22 and the decrease in the matte region 21 emphasize the three-dimensional effect of the sheet surface.

[0029] Furthermore, the pressing blade 47 of the pressing plate 45 presses down on the sheet surface of the sheet material 37, creating an edge groove 24. The edge groove 24 is formed in a circular arc shape in cross-section, following the tip of the pressing blade 47. The pressing blade 47 partially compresses the area slightly inside the outer edge of the glossy region 22, forming the edge groove 24 inside the glossy region 22 along the outer edge of the glossy region 22. In this way, not only is the three-dimensional effect emphasized by the difference in reflectivity and height difference between the matte region 21 and the glossy region 22, but the step of the edge groove 24 clarifies the boundary 29 between the glossy region 22 and the matte region 21, resulting in a decorated sheet 5 with an even more emphasized three-dimensional effect on the sheet surface.

[0030] As shown in Figure 6(C), in the decorative sheet 5, one edge 26 of the edge groove 24 of the glossy region 22 is connected to the outer edge of the matte region 21. The edge groove 24 is recessed in an arc shape so that it is lower than the matte region 21, and the slope of the glossy region 22 rises gently from the other edge 27 of the edge groove 24. That is, one edge 26 of the edge groove 24 is positioned at the boundary 29 between the matte region 21 and the glossy region 22, and the slope rises from a position that extends inside the glossy region 22 beyond the boundary between the matte region 21 and the glossy region 22. In this case, the deformation of the glossy region 22 is large not only at the shoulder portion 25 of the glossy region 22, but also at both edges 26 and 27 of the edge groove 24.

[0031] In this way, a difference in height is created between the matte area 21 and the glossy area 22, and a groove 24 is provided along the outer edge of the glossy area 22, thereby forming the decorative sheet 5 three-dimensionally. In the matte area 21, light is diffusely reflected, making the surface appear rough, while in the glossy area 22, light is specularly reflected, making the surface appear smooth, thus emphasizing the contrast. In particular, the reflection is strong at the shoulder portion 25, where the deformation of the glossy area 22 is large, and at both edges 26 and 27 of the groove 24. As the groove 24 becomes brighter due to reflected light, the boundary between the matte area 21 and the glossy area 22 becomes clearer, emphasizing the three-dimensionality and improving the decorative effect.

[0032] As described above, according to this embodiment, a three-dimensional pattern is applied to the decorative sheet 5 using a pseudo-embossing technique based on the difference in reflectivity between the matte region 21 and the glossy region 22. Furthermore, the formation of edge grooves 24 in the glossy region 22 results in stronger reflection at both edges 26 and 27, where deformation is greater due to the edge grooves 24. As a result, the boundary between the matte region 21 and the glossy region 22 becomes clearer due to the step and reflection of the edge grooves 24, further emphasizing the three-dimensional effect of the sheet surface and improving the decorative appeal of the decorative sheet 5.

[0033] In this embodiment, a difference in height is provided between the matte area and the glossy area, but this difference in height is not required.

[0034] Furthermore, although the coated cardboard is color-printed with standard ink in this embodiment, it may also be printed using ink such as pseudo-silver to make the coated cardboard appear as if it has been foil-stamped.

[0035] Furthermore, although the decorative sheet has a grid pattern in this embodiment, the pattern of the decorative sheet is not limited. In other words, the matte and glossy areas are not limited to a diamond shape.

[0036] Furthermore, in this embodiment, the edge groove is formed in an arc shape when viewed in cross-section, but the groove shape of the edge groove is not particularly limited.

[0037] Furthermore, in this embodiment, the matte layer is formed by applying a glossy varnish on a repellent varnish, but the method of forming the matte layer is not particularly limited as long as the matte layer is formed with a rough texture.

[0038] Furthermore, although the glossy layer is formed by applying a glossy varnish in this embodiment, the method of forming the glossy layer is not particularly limited as long as the glossy layer has a smooth texture.

[0039] Furthermore, in the first and second embodiments, the decorative sheet is formed from a double-sided corrugated cardboard sheet, but the decorative sheet may also be formed from single-layer paper or the like.

[0040] As described above, the first embodiment is a decorative sheet (5) on which printing and embossing are applied to the sheet surface, comprising a matte region (21) on which a matte layer (34) with a rough texture is provided on the sheet surface, and a glossy region (22) on which a glossy layer (35) with a smooth texture is provided on the sheet surface, with an edge groove (24) formed inside the glossy region along the outer edge of the glossy region. With this configuration, a three-dimensional pattern is applied to the sheet surface using a pseudo-embossing technique based on the difference in reflectivity between the matte region and the glossy region. In addition, because an edge groove is formed in the glossy region, the reflection is stronger at both edges on either side where deformation is greater at the edge groove. As a result, the boundary between the matte region and the glossy region becomes clear due to the step and reflection of the edge groove, the three-dimensionality of the sheet surface is further emphasized, and the decorative appeal of the decorative sheet is improved.

[0041] In the second embodiment, the sheet surface has alternating matte and glossy areas. With this configuration, the decorative properties of the decorative sheet are improved by the alternating matte and glossy areas.

[0042] In the third embodiment, as in the second embodiment, in a cross-sectional view along the direction of alignment of the matte and glossy regions, the distance from the boundary between the matte and glossy regions to the edge groove is greater on one side than on the other side in the alignment direction. With this configuration, the decorative properties of the decorative sheet are improved by giving regularity to the areas where the reflection of the alternating patterns is emphasized.

[0043] The fourth embodiment is one of the first to third embodiments in which the portion inside the edge groove of the glossy region is formed to be higher than the matte region. This configuration further emphasizes the three-dimensional effect of the sheet surface and improves the decorative appeal of the decorative sheet.

[0044] The fifth embodiment is a linear gloss region provided on the sheet surface in any one of the first to fourth embodiments, wherein the matte layer is formed thicker than the gloss layer, and fold lines (L1, L4, L6) are provided inside the linear gloss region. With this configuration, the fold lines are emphasized by the linear gloss region, improving the decorative appeal of packaging boxes and the like. In addition, because fold lines are provided in the thin gloss layer, the gloss layer is less likely to crack even when the decorative sheet is folded along the fold lines.

[0045] The sixth aspect is one of the first to fifth aspects, in which the distance from the outer edge of the glossy area to the edge groove is greater than the dimensional tolerance. With this configuration, even if there is a slight misalignment in the outer edge or edge groove of the glossy area during the manufacturing of the decorative sheet, the edge groove will not protrude from the outer edge of the glossy area.

[0046] The seventh embodiment is a method for manufacturing a decorative sheet in which a predetermined pattern is formed on the sheet surface with a matte layer having a rough texture and a glossy layer having a smooth texture, comprising the steps of printing a repellent varnish on the sheet surface according to the predetermined pattern, printing a glossy varnish on the sheet surface after printing the repellent varnish, and pressing the sheet surface with a pressing blade to create edge grooves, wherein the matte layer is formed by curing the glossy varnish while it is repelled by the repellent varnish, and the glossy layer is formed by curing the glossy varnish in areas other than the repellent varnish, and the sheet surface is formed with a matte region where the matte layer is provided and a glossy region where the glossy layer is provided, and edge grooves are formed inside the glossy region along the outer edge of the glossy region. With this configuration, a three-dimensional pattern is applied to the sheet surface using a pseudo-embossing technique based on the difference in reflectivity between the matte region and the glossy region. In addition, because edge grooves are formed in the glossy region, the gloss is stronger at both edges where deformation is greater at the edge grooves. As a result, the boundary between the matte region and the glossy region is clearly defined by the step and gloss of the edge grooves, the three-dimensionality of the sheet surface is further emphasized, and the decorative properties of the decorative sheet are improved.

[0047] In the eighth aspect, in the process of forming the edge groove in the seventh aspect, a support plate (42) that supports the sheet material (37) and a pressing plate (45) on which a pressing blade (46) is installed are used, and a cushioning material (48) corresponding to the matte layer is installed on the pressing plate, and the matte layer is pressed down by the cushioning material so that the matte area is lower than the glossy area. With this configuration, the matte area is lowered as the matte layer is pressed down by the cushioning material, which further emphasizes the three-dimensional effect of the sheet surface and improves the decorative effect of the decorative sheet.

[0048] In the ninth embodiment, in the process of forming the edge groove in the seventh or eighth embodiment, a support plate for supporting the sheet material and a pressing plate on which a pressing blade is installed are used, and a protrusion (CAD face plate 44) corresponding to the glossy layer is installed on the support plate, and the glossy layer is pushed up by the protrusion so that the glossy area is higher than the matte area. With this configuration, the glossy area is raised by the protrusion pushing up the glossy layer, which further emphasizes the three-dimensional effect of the sheet surface and improves the decorative appeal of the decorative sheet.

[0049] Although this embodiment has been described, other embodiments may include combinations of the above embodiments and modifications, either entirely or partially.

[0050] Furthermore, the technology of the present invention is not limited to the embodiments described above, and may be modified, substituted, or transformed in various ways without departing from the spirit of the technical idea. Moreover, if the technical idea can be realized in a different way by advances in the technology or by other derived technologies, it may be implemented by that method. Accordingly, the claims cover all embodiments that may fall within the scope of the technical idea. [Explanation of Symbols]
