An embodiment of a container for a three-dimensional ornament according to the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a principle cross-sectional view showing a first embodiment of a three-dimensional decorative container 10 according to the present invention. The three-dimensional decorative container 10 is a can container such as a tubular tin can. The container 10 may be a resin container such as plastic, a paper container, a glass container, or a wooden container instead of the can container. The shape of the container is not limited to a tubular shape, but may be a box shape, a three-dimensional shape of animals and plants, and various other three-dimensional containers.

The container 10 constitutes a decorative object having a three-dimensional pattern on the surface of the tubular container body 11, and the decorative sheet 12 is wrapped around the outer surface of the container body 11. The decorative sheet 12 has a structure in which a large number of convex lens-shaped protrusions 14 formed on the surface of the transparent resin sheet 13 with a standard number of screen lines are arranged in a hexagonal pattern or a grid pattern at regular pitch intervals to form a standard continuous pattern. Is. The decorative sheet 12 is integrally provided by being wound around the outer surface of a container body 11 such as a tubular tin can, or by being adhered with an adhesive 15.

In the decorative sheet 12, a standard continuous pattern of convex lenticular projections 14 is partially or wholly formed on the surface of the transparent resin sheet 13. The standard continuous pattern may be a concave lens-shaped recess or a concave-convex shape required for the decorative function instead of the convex lens-shaped protrusion 14. Further, the convex lens-shaped protrusions 14 provided on the surface of the transparent resin sheet 13, the concave lens-shaped dents, or the unevenness required for the decorative function are not only arranged in an aligned manner but also arranged at an irregular required pitch. Good.

In addition, the standard screen line number is configured by selecting any single screen line number from, for example, a screen line number range of 60 to 300 lines. For the standard screen line number, for example, a screen line number of 100 lines is selected. The number of screen lines refers to the number of halftone dots between 1 inch or 1 cm.

Examples of the material of the transparent resin sheet 13 include a transparent material such as polyethylene, polypropylene, polyester, nylon, polyurethane, polyvinyl chloride, polyvinyl chloride, and polyacrylic, a translucently colored resin material, and soil or seawater. It may be formed of a degradable resin material that is decomposed by microorganisms or the like.

Even if the decorative sheet 12 is a single transparent resin film in which a concavo-convex shape portion is formed on the surface of the transparent resin sheet 13 by a convex lens-shaped protrusion 14 or the like, the sheet having the concavo-convex shape and the transparent resin sheet 13 may be formed. A plurality of transparent resin films of different members may be bonded together.

When the tubular container body 11 is a metal can such as a tin can, the can container is subjected to a molding process such as a roll process, a corner cutting process, or a hemming and seaming portion forming process from the metal sheet material at the time of manufacturing the can. Some are manufactured. In the manufactured metal can, a seaming portion 18 is formed in the can container. The hemming portion 18 has a raised surface formed on the outer surface side or the inner surface side as compared with the tubular outer surface of the container body 11. The metal can may be formed by deep drawing or shallow drawing. A deep-drawn can container means a container whose depth is deeper than the diameter of the container, and a shallow-drawn can container means a container whose depth is shallower than the diameter of the container.

In the decorative sheet 12 wound around the container body 11, a glue margin portion 19 is provided in a flat shape at one sheet end portion (sheet tip portion, sheet edge portion) of the transparent resin sheet 13. The other sheet end portion (sheet rear end portion, sheet edge portion) of the decorative sheet 12 is superposed on the glue margin portion 19. The edges of the sheets are joined to each other via a film adhesive and integrated. The decorative sheet 12 is thinned by pressing one end (the tip of the sheet) of the transparent resin sheet 13 in the wall thickness direction to form a flat glue margin portion 19. The glue margin portion 19 is formed by not forming the convex lenticular projections 14 on the back surface side of the transparent resin sheet 13 and by crushing the formed convex lenticular projections 14 by partial processing means such as heat welding.

In the decorative sheet, one sheet edge portion of the transparent resin sheet 13 is pressed to one side in the sheet wall thickness direction to form a thin-walled glue margin portion 19, and the glue margin portion 19 has the other sheet edge. The portions are overlapped with each other via a film-like adhesive, and the edge portions of the sheets are connected and integrated at the joint portion. Since the other side of the transparent resin sheet 13 is pressed to the other side in the sheet wall thickness direction to be thinned, when the sheet ends of the decorative sheet 12 are overlapped and joined, the joint portion is smooth without a sheet step. A seam is constructed. In the decorative sheet 12, even if the transparent resin sheet 13 is wound around the container body 11, the sheet ends are formed with non-stepped joints, so that the sheet seams are raised and no steps are formed.

Even if the transparent resin sheet 13 is wound around the container body 11 to form the three-dimensional decorative container 10, the outer line shape of the container 10 is formed by forming a smooth non-stepped joint at the seam of the decorative sheet 12. Is good, and it becomes a container for a three-dimensional decoration capable of expressing a three-dimensional pattern with a three-dimensional effect.

Further, when the container 10 of the three-dimensional decoration is made of metal such as a tin can, a seaming portion 18 is formed in the container body 11. The hemming portion 18 is formed with a convex surface that rises from the surface of the container body 11 to the outer surface side or the inner surface side.

When the seaming portion 18 is formed on the inner surface side of the container body 11, the transparent resin sheet 13 wound around the container body 11 forms a non-stepped joint at the sheet joint. Even if the hem portion 18 of the main body 11 is overlapped, the outer surface of the joint position is formed as a smooth surface without uneven surfaces, and the appearance shape is kept good.

The transparent resin sheet 13 is shifted in the circumferential direction so that the sheet seam does not overlap with the seaming portion 18 in consideration of the position of the seaming portion 18 of the container body 11 as in the conventional special decorative sheet. It is not necessary to attach the transparent resin sheet 13, and the degree of freedom in winding the transparent resin sheet 13 can be improved. A large degree of freedom can be given to the winding of the decorative sheet 12.

The three-dimensional decorative container 10 has a configuration in which a single transparent resin sheet 13 is wound around a container body 11 which is a decorative object and attached with an adhesive 15, but a plurality of glue margins 19 are provided. The edges of the plurality of decorative sheets 12 may be overlapped and connected to each other and attached to the container body 11.

Further, the decorative sheet 12 has a configuration in which the rear end portion of the sheet is overlapped on the surface of the glue margin portion 19 at the end portion (front end portion of the sheet) of the transparent resin sheet 13 and is attached with a film-like adhesive. It is not limited to bonding with a film-like adhesive. The transparent resin sheet 13 may be one in which the end portions of the sheets are overlapped with each other and integrally bonded by pressure bonding or heat sealing.
Similarly, in the decorative sheet 12, the transparent resin sheet 13 and the container body 11 are attached with an adhesive 15, but the adhesive 15 is not always used.

For example, the transparent resin sheet 13 and the container body 11 may be directly adhered to each other by applying a pressure between the transparent resin sheet 13 and the container body 11, and further, the transparency by heat sealing may be used. The resin sheet 13 and the container body 11 may be bonded to each other, and the transparent resin sheet 13 and the container body 11 may be bonded to each other.

Further, since the decorative sheet 12 has a structure in which one edge portion (adhesive margin portion 19 at the tip portion) of the transparent resin sheet 13 overlaps the other sheet edge portion (rear end portion), only the glue margin portion 19 is used. By sticking with a film-like adhesive, the decorative sheet 12 can be held by the container body 11. In this case, if the transparent resin sheet 13 is made of a resin material having a contractile force more than that of the container body 11, the container body 11 and the decorative sheet 12 can be held more firmly.

FIG. 2 is a principle cross-sectional view showing a modified example of the container of the three-dimensional ornament. For the container 10A, a metal sheet material having high moldability such as an aluminum can may be formed by deep drawing or shallow drawing to manufacture the container body 11A. The container body 11A formed by this molding process becomes a smooth tubular container without a seaming portion (seam).

In the three-dimensional decorative container 10A shown in FIG. 2, the container body 11A is formed into a smooth tubular shape having no uneven seams on the outer surface and the inner surface. For this reason, the decorative sheet 12 does not have uneven seams when the container body 11A is attached, and does not have a seaming portion, so that the appearance shape of the container is kept good and special consideration must be given. There is no.

The transparent resin sheet 13 can be easily attached by simply wrapping it around the outer surface on the container body 11A and joining the edges of the transparent resin sheet 13 on top of each other. Becomes good.

In FIG. 2, the seamless container body 11A is manufactured by deep drawing or shallow drawing, and the transparent resin sheet 13 is wound around the outer surface of the container body 11A so that the sheet ends of the glue margin 19 are non-stepped. Anything that constitutes a joint may be used. The external shape of the container body 11A may be a tubular three-dimensional shape, an animal or plant shape, or another three-dimensional shape. Further, the container body 11A may be formed in a virtual space having no substance, and only the transparent resin sheet 13 may be formed into a three-dimensional shape by superimposing the glue margin portion 19 to form a container structure having a required rigidity.

FIG. 3 is an enlarged cross-sectional view showing the details of the joint portion (seam) of the decorative sheet 12 wound around the container bodies 11 and 11A shown in FIGS. 1 and 2. In the decorative sheet 12, the transparent resin sheet 13 is attached to a container body 11 (11A) having a tubular shape or a box shape by an adhesive 15 or a heat seal or thermocompression bonding. A lenticular standard continuous pattern such as a convex lenticular projection 14 formed on the surface of the transparent resin sheet 13 with a standard number of screen lines is formed.

Further, on the back surface side of the transparent resin sheet 13, a required printing pattern 20 printed with a required screen line number different from the standard screen line number of the standard continuous pattern on the surface of the transparent resin sheet 13 is formed. For example, assuming that the standard number of screen lines is 100, a plurality of required number of screen lines is 80, 90, 100, 110, and 120, and the required print pattern 20 of the screen lines is printed. Therefore, the decorative sheet 12 can obtain a moire pattern by the action of the convex lenticular projection 14 forming the standard continuous pattern and the required printing pattern 20 printed in a required continuous pattern different from the standard continuous pattern. The moire pattern has a depth and a three-dimensional effect by changing the standard number of screen lines on the front surface of the transparent resin sheet 13 and the number of screen lines of the required printing pattern 20 on the back side of the sheet. The larger the difference between the number of screen lines of the required print pattern 20 and the number of standard screen lines, the deeper the decorative effect of the three-dimensional pattern can be obtained, as will be described later. The required print pattern 20 having a screen line number smaller than the standard screen line number is visually recognized by floating toward the front side, and the required print pattern 20 having a large screen line number is visually recognized by sinking to the back side. The greater the difference in the number of screen lines between the two, the greater the amount of ups and downs of characters and patterns.

It should be noted that, in the required printing portion where the number of screen lines of the required printing pattern 20 is the same as the standard number of screen lines forming the standard continuous pattern, flat characters and patterns without a three-dimensional effect appear.
Further, the number of screen lines of the required printing pattern 20 may be changed for each required printing portion as necessary so that different moire patterns can be obtained.

By providing a plurality of required print patterns 20 printed with a required number of screen lines different from the standard number of screen lines for each required print part, a three-dimensional three-dimensional effect obtained for each required print part can be obtained. The depths are different from each other, and a three-dimensional three-dimensional decorative effect (three-dimensional pattern) that can obtain three-dimensional depths in multiple stages can be obtained on the surface of the container body 11.

By wrapping the decorative sheet 12 around a container body 11 such as a metal can and joining them via a glue margin portion 19, a non-stepped joint surface without a step at the seam is obtained, and the appearance shape is good. The three-dimensional decorative container 10 can express a three-dimensional pattern having a three-dimensional effect on the surface of the container, and when applied for decoration, the appearance shape of the container becomes good.

In the decorative sheet 12, the required printing pattern 20 is provided on the back surface side of the transparent resin sheet 13, but the required printing pattern 20 may be provided by printing directly on the front surface of the container body 11 (11B). Actually, a lenticular continuous pattern of convex lenticular projections 14 having a standard screen number is provided on the surface of the transparent resin sheet 13, and a required printing pattern 20 (continuous pattern or) having a screen number different from the standard screen number is provided on the back side of the sheet. It suffices if the print layer of (atypical pattern) is printed. Further, in order to protect the required printing pattern 20, another transparent film may be provided between the adhesive 15 and the surface provided with the required printing pattern 20 on the back surface side of the transparent resin sheet 13.
FIG. 4 is a cross-sectional view showing a modified example of the decorative sheet 12A wound around the container body 11 (11A).

The decorative sheet 12A includes a transparent resin film 22 in which a transparent resin sheet 13 has a convex lenticular projection 14 having a standard screen number formed on its surface, and a single or a plurality of printed sheets having a screen number different from the standard screen number. The resin film 23 provided with the required printing pattern 20 and the intermediate resin film 24 interposed between the two resin films 24 form a laminated structure. The transparent resin sheet 13 is integrally attached to both sides of the intermediate resin film 24 so that each continuous pattern faces the outer surface. The decorative pattern 25 printed on the convex lens-shaped protrusion 14 side of the intermediate resin film 24 is printed with a standard screen number of lines. Therefore, on the transparent resin sheet 13, a moire pattern cannot be obtained in the pattern portion of the decorative pattern 25. Since the moire pattern is obtained at the printed portion of the required print pattern 20, a three-dimensional decorative effect in which the decorative pattern appears to be floating can be obtained.

In the decorative sheet 12A, the decorative pattern 25 is printed on the intermediate resin film 24, but the surface to be printed may be between the convex lens-shaped protrusion 14 and the outer surface of the container body 11 (11A). The decorative pattern 25 may be printed directly on the outer surface of the container body 11 (11A).

Further, the decorative sheet 12A shown in FIG. 4 is wrapped around the outer surface of the container body 11 (11A). The decorative sheet 12A is adhered to the container body 11 (11A) with an adhesive 15 or a heat seal. The decorative sheet 12A to be wrapped around the container body 11 (11A) is attached with a film-like adhesive 26 so that the rear end portion of the sheet is overlapped with the surface of the flat glue margin portion of the sheet end portion (tip portion). In the decorative sheet 12A shown in FIG. 4, the joints between the sheet ends of the transparent resin sheet 13 are configured in the same manner as the non-stepped joints shown in FIG. 3, and the sheet ends have no steps. A smooth joint can be obtained.

Further, when the adhesive 15 of the decorative sheet 12 (12A) is applied, as shown in FIGS. 3 and 4, it is not necessary to apply the adhesive 15 to the entire surface of the transparent resin sheet 13, and the transparent resin sheet 13 is applied. It suffices as long as it has a function that can be partially attached to the container body 11 (11A). Further, the transparent resin sheet 13 is wound around the outer surface of the container body 11 (11A), and the sheet edges are bonded to each other at the glue margin portion 19, so that a sufficient bonding function can be obtained, or the container body 11 (11A). ), It is not always necessary to attach the transparent resin sheet 13 with the adhesive 15.

The decorative sheet 12 (12A) has a glue margin portion having a shape suitable for various uses on the sheet edge of the transparent resin sheet 13 provided with a continuous pattern of at least two different screen lines having a function of forming a moire function. By providing 19 and joining them, the transparent resin sheets 13 can be joined to each other. Further, by attaching the decorative sheets 12 and 12A to the container body 11 (11A) with the adhesive 15, it is possible to apply the three-dimensional three-dimensional pattern decoration function to the container body 11 (11A) such as a metal can. It becomes.

Further, as shown in FIG. 5, the three-dimensional decorative container 10 (10A) has a tubular or box-shaped container body 11 (11A), for example, by molding a plate-shaped metal plate 29 into a required shape. It is composed. The plate-shaped metal plate 29 has a printing layer 30 printed on the surface. A transparent resin sheet 13 is adhered onto the print layer 30 via an adhesive 15 to produce a three-dimensional decorative container 10 (10A) integrally bonded to the container body 11 (11A).

The decorative sheet 12 (12A) has the partial cross-sectional structure shown in FIG. The decorative sheet 12 (12A) has a lenticular continuous pattern of convex lenticular projections 14 formed on the surface of the transparent resin sheet 13 with a standard number of screen lines, and a printing layer 30 of a required printing pattern printed on a metal plate 29. As a result, a container 10 (10A) having a three-dimensional pattern having a three-dimensional effect is created on the surface of the metal plate 29. In this case, since the printing layer 30 is provided on the front surface of the metal plate 29, it is not necessary to provide the required printing pattern on the back surface side of the transparent resin sheet 13, but a printing layer with a decorative pattern may be provided. The lenticular continuous pattern formed on the surface of the transparent resin sheet 13 is a convex lenticular projection 14 formed by a standard screen line number, and the print layer 30 printed on the metal plate 29 is a standard screen line. It is a print layer of a required print pattern with a number of screen lines different from the number. A decorative pattern printed with a standard number of screen lines may be formed on the back surface of the transparent resin sheet 13, but a printing layer of the required printing pattern may not be provided.

The metal plate 29 provided with the decorative sheet 12 (12A) is provided with a metal such as a tin plate, an iron plate, an aluminum plate, a stainless steel plate, a surface-treated steel plate, a zinc plate, and a nickel plate according to the intended use. The metal plate 29 has a plate thickness of about 0.15 mm to 2 mm, and tin cans having a thickness of about 0.2 mm to 0.4 mm are used for cans such as confectionery cans, tea cans, canned cans, and bathing agent cans. Be done.

Further, as the adhesive 15, a resin material such as an acrylic resin, a polyester resin, an epoxy resin, a urea resin, a melanin resin, or a cyanoacrylate resin is used. The adhesive 15 is selected according to the type of resin material used for the transparent resin sheet 13. For example, when a polyester resin film is used for the transparent resin sheet 13, a polyester resin is used as the adhesive. When a vinyl chloride resin film is used, polyethylene resin is used as an adhesive. The thickness of the adhesive layer formed by the adhesive 15 is about 30 μm to 50 μm. Acrylic resin is used as an adhesive such as double-sided tape for normal temperature adhesion.

When a polyethylene resin is used for the adhesive 15, the bonding temperature is about 90 ° C. to 120 ° C., when a polyester resin is used, about 180 ° C. to 200 ° C., and when a nylon resin is used, about 160 ° C. When a polypropylene (P / P) resin is used, it is adhered at about 80 ° C.

Further, the transparent resin sheet 13 may be a transparent material capable of transmitting light, and may be colored translucently. Further, the transparent resin sheet 13 may be a material that is transparent enough to allow light to pass through as a result of being attached onto the printing layer 30 of the plate-shaped metal plate 29 even if it is colored. As the material of the transparent resin sheet 13, a synthetic resin film such as polyethylene, polypropylene, polyester, nylon, polyurethane, polyvinyl chloride, polyvinyl chloride, and polyacrylic is used, and the film thickness is about 20 μm to 200 μm. ..

On the sheet surface of the transparent resin sheet 13, a large number of convex lens-shaped protrusions 14 are arranged in a halftone dot pattern by roll pressing. The convex lens-shaped protrusions 14 form a hexagonal or grid-like uneven pattern on the sheet surface as a continuous (predetermined) lens-like pattern, and the lens effect can be exhibited.

The convex lenticular projections 14 having a predetermined pattern formed on the transparent resin sheet 13 are patterned in a pitch arrangement having a standard screen number of lines. The standard screen number of lines is appropriately selected from, for example, the number of lines in the range of 75 to 300 lines. The number of screen lines refers to the number of black lines (halftone dots) between 1 cm and 1 inch. Instead of providing the convex lens-shaped protrusions on the sheet surface of the transparent resin sheet 13, a concave lens-shaped recess may be provided to form a concave-convex pattern.

The patterns 32a, 32b, 32c of the print layer 30 printed on the surface of the metal plate 29 have the patterns 32a, depending on the positional relationship with the convex lens-shaped protrusions 14 (hereinafter referred to as protrusions) formed on the transparent resin sheet 13. The visual states of 32b and 32c are different.

As shown in FIG. 6 (A), in the portion where the pattern 32a and the protrusion 14 completely overlap, the pattern 32a can be recognized from any direction. As shown in FIG. 6 (B), the protrusion 14 and the pattern When the overlap of 32b deviates by approximately the radius of the protrusion 14, the pattern 32b can be visually recognized when viewed from the X direction, the pattern 32b cannot be recognized when viewed from the Y direction, and the pattern 32b can be seen depending on the viewing direction. Or you can't see it.

Further, as shown in FIG. 6C, when the pattern 32c is displaced by the radius of the protrusion 14 or more, not only the pattern cannot be seen from the Y direction, but also the pattern 32c becomes difficult to see from the X direction, and the pattern 32c is completely displayed. Cannot be recognized.

Therefore, the patterns 32a, 32b, and 32c of the print layer 30 printed on the surface of the metal plate 29 change depending on the relative positional relationship with the convex lens-shaped protrusions 14, that is, the viewing angle.

As shown in FIG. 7, patterns A, B, C, D, and E having different screen lines are printed on the surface of the metal plate 29. The patterns A, B, C, D, and E are printed with a predetermined pattern (concavo-convex pattern) having a standard number of screen lines formed on the sheet surface of the transparent resin sheet 13 and a fixed ratio of screen lines. For example, assuming that the standard number of screen lines is 100, the number of screen lines of patterns A, B, C, D, and E is a constant ratio of 90, 95, 100, 105, 110 (or 80, 90, 100, 110, 120). Patterns A, B, C, D, and E are formed in proportion. For each pattern A, B, C, D, and E, a plurality of color-separated printing plate making 34s are prepared for each pattern so that each pattern can be color-printed, and the colors are displayed on the surface of the metal plate 29. Printing patterns A, B, C, D, and E may be configured.

In order to form patterns A, B, C, D, and E having different screen lines on the surface of the metal plate 29, as shown in FIG. 8, each pattern A, B, C, D, and E is printed differently. It is printed using the plate making 34. Therefore, in order to print the patterns A, B, C, D, and E on the surface of the metal plate 29, the printing plate making 34 in which each pattern is formed is used, and each printing plate making 34 is aligned and printed. ..

The patterns A, B, C, D, and E formed on each printing plate making 34 may be printed in different colors, shapes, and patterns, and further, each printing plate making 34 may be printed with a required number of screen lines. Plate making is performed from the original plate so that B, C, D, and E can be printed. Although the patterns A, B, C, D, and E are printed at different positions on the metal plate 29, the patterns A, B, C, D, and E are actually printed so as to overlap each other.

In printing the patterns A, B, C, D, and E on the metal plate 29, the surface of the metal plate 29 is precoated at a baking temperature of 140 ° C. to 160 ° C. to form a base layer 35, and the base layer 35 is printed on the base layer 35. Print and bake in a heated state of 140 ° C to 210 ° C. By this baking printing, the printing layer 30 is firmly bonded to the metal plate 29, and printing is performed so as not to be peeled off. The patterns A, B, C, D, and E may be formed on the metal plate 29 by irradiating the printed surface with UV (ultraviolet rays) and heating and drying the printed surface.

Then, patterns A, B, C, D, and E having different screen lines are printed on the metal plate 29, and a transparent resin is used on the surface of the printed metal plate 29 using a transparent adhesive 15 or an adhesive. The sheet 13 is attached to form a decorative sheet 12 (12A) having an integrally bonded structure as shown in FIGS. 3 and 4.

As shown in FIG. 5, the decorative sheet 12 (12A) has a large number of convex lenticular projections 14 formed in a concave-convex pattern on the sheet surface of the transparent resin sheet 13 in a predetermined pattern. Since the convex lens-shaped protrusions 14 are formed in a halftone dot shape (turtle shell shape, grid shape) with a standard number of screen lines, the imaging positions generated by each convex lens-shaped protrusion 14 and each pattern A, B, C, D, E can be determined. , Each pattern A, B, C, D, E looks different due to the lens effect shown in FIG.

Since the position formed by the protrusion 14 and the pattern A and the position formed by the protrusion 14 and the patterns B, C, D, and E are different, the patterns A, B, C, D, and E are different. It is recognized as being on a plane.

Therefore, when the viewing angle is changed, the patterns of each pattern A, B, C, D, and E can be seen as moving while changing on different planes, and the three-dimensional pattern with a three-dimensional effect can be seen on the metal plate 29. Can be expressed on the surface of. Patterns A and B with a screen line number larger than the standard screen line number are visually recognized by rising to the front side, and patterns D and E having a screen line number smaller than the standard screen line number are seen by sinking to the back side.

The larger the difference between the standard number of screen lines and the number of screen lines of each pattern A, B, C, D, and E, the more the screen lines are raised to the front side or sunk to the back side, and the number of screen lines is increased. The smaller the difference from the above, the smaller the amount of lifting and sinking will be visually recognized.

The decorative sheet 12 (12A) shown in FIG. 5 is printed on the surface of the metal plate 29, and the transparent resin sheet 13 is bonded to the surface of the printed metal plate 29 via an adhesive 15 or an adhesive. , Integrated. At that time, the film thickness of the transparent resin sheet 13 is 20 μm to 200 μm, the layer thickness of the adhesive 15 is 10 μm to 50 μm, and the layer thickness of the printing layer 30 is several μm to several μm, preferably about 10 μm. .. Further, since the transparent resin sheet 13 and the adhesive 15 are integrally bonded, the boundary layer is actually eliminated and does not exist.

Further, the screen angles of the patterns A, B, C, D, and E printed on the surface of the metal plate 29 are adjusted according to the film thickness of the transparent resin sheet 13. Specifically, the thicker the film thickness of the transparent resin sheet 13, the smaller the screen angle, and the smaller the screen angle, the larger the depth between the patterns A, B, C, D, and E printed on the surface of the metal plate 29. A three-dimensional effect that gives a feeling of
Next, a method of manufacturing the decorative sheet 12 (12A) will be described with reference to FIG.

In FIG. 9, a tin plate is used as the plate-shaped metal plate (metal base material) 29 used for the decorative sheet 12 (12A), and the surface of the tin plate is baked at 140 ° C. to 160 ° C. to precoat and the base layer. Form 35. Patterns A, B, C, D, and E are sequentially printed by printing a large number of times by aligning the surfaces of the metal plate 29 on which the base layer 35 is formed by using different printing plates for each color. The patterns A, B, C, D, and E printed on the metal plate 29 are printed in a heated state of 140 ° C. to 210 ° C. with different screen lines and different colors. For example, as shown in FIG. 8, when five patterns A, B, C, D, and E are printed, the number of screen lines of the pattern C is the convex lenticular projection 14 formed on the sheet surface of the transparent resin sheet 13. Matches the standard screen line count of.

The print layers 30 of the patterns A, B, C, D, and E are printed on the transparent resin sheet on the sheet surface side of the transparent resin sheet 13 fed from the feeding roller 31 instead of being printed directly on the metal plate 29. , C, D, E print layers 30 may be printed. On the surface side of the transparent resin sheet, a standard continuous pattern formed by a large number of convex lenticular projections 14 with a standard screen number of lines is formed. In this case, the transparent resin sheet 13 has a standard continuous pattern formed on the front surface side of the sheet with a standard number of screen lines, and the print layers 30 of the patterns A, B, C, D, and E are printed on the back surface side of the sheet. ..

When pattern C is a standard screen line number, patterns A and B and patterns D and E are printed with a screen line number that increases and decreases at a constant rate from the standard screen line number of pattern C. Specific characters, symbols, shapes, figures, patterns in which patterns are arranged, patterns, and the like are printed on the patterns A to E.

The metal plate 29 to be printed may be a continuous strip plate or a single leafy product. FIG. 9 shows an example of printing on a sheet metal plate 29. The printed metal plate 29 may be a container body 11 (11A) formed into a cylindrical shape or a block shape.

The printed metal plate 29 whose surface is printed is once deposited on the feeder 36, or is directly guided to the preheating device 37, and is preheated by the preheating device 37 using hot air. The preheating device 37 may directly heat the printed metal plate 29 with a heater or the like.

The temperature of preheating by the preheating device 37 is about several tens of degrees Celsius to 200 ° C., and the preheating temperature is appropriately set according to the type of the transparent resin sheet 13 tightly bonded to the surface of the printed metal plate 29. To. When a polyester (PET) resin is used for the transparent resin sheet 13, it is preheated to about 150 ° C. to 180 ° C. The polyester resin is an environmentally friendly resin, and when a polyvinyl chloride resin is used for the transparent resin sheet 13, it is preheated at a temperature of 100 ° C. or lower.

The printed metal plate 29 preheated by the preheating device 37 is subsequently guided to the hot press device 38, but the surface of the printed metal plate 29 is directly guided via the adhesive 15 before being guided to the hot press device 38. It is sequentially covered with a strip-shaped transparent resin sheet 13. A large number of convex lenticular protrusions 14 are formed on the sheet surface of the transparent resin sheet 13 in a predetermined pattern at pitch intervals of a standard screen number of lines, while an adhesive is formed on the back surface of the film immediately before being guided by the hot press device 38. This adhesive may be formed in advance in the form of a sheet, and the transparent resin sheet 13 may be superposed on the printed metal plate 29 via the adhesive. Further, the printed metal plate 29 may be molded into a tubular or box-shaped container, and the transparent resin sheet 13 may be wound around the container body 11 (11A) of the molded metal container to be laminated and integrated.

In the hot press device 38, the transparent resin sheets 13 laminated on the printed metal plate 29 are brought into close contact with each other by using thermocompression bonding rolls 39 and 39, and thermocompression bonding is performed. The thermocompression bonding temperature is 150 ° C. to 180 ° C. when a polyester (PET) resin film is used for the transparent resin sheet 13, and 100 ° C. or lower when a polyvinyl chloride resin film is used.

As the adhesive, an adhesive having good compatibility with the metal surface of the printed metal plate 29 and having strong adhesiveness and adhesion is used, and an adhesive is selected according to the type of the metal plate 29 to be used. .. When a tin plate is used as the metal plate 29, the polyester resin cannot be adhered to the printed metal plate 29 by hot pressing at 100 ° C. or lower.

The transport speed in the hot press device 38 is appropriately set according to the thickness dimension of the printed metal plate 29, and the crimping pressure by the thermocompression bonding rolls 39 and 39 is the thickness and dimension of the printed metal plate 29 and the sheet of the transparent resin sheet 13. Adjusted by thickness. Actually, when the printed metal plate 29 is a sheet-fed product, it is hot-pressed at a transport speed of about 15 to 100 sheets / minute. When the container body is composed of the printed metal plate 29, it is hot-pressed at a predetermined peripheral speed around the outer circumference of the container body. By this hot press, the transparent resin sheet 13 is superposed on the printed metal plate 29 and brought into close contact with each other, and is integrally joined.

The transparent resin sheet 13 bonded on the surface of the printed metal plate 29 is subsequently cut by a pressing device or a cutting device (not shown), and the ear pieces are cut to form the decorative sheet 12 (12A). When the decorative sheet 12 (12A) is manufactured, heat treatment is performed in the hot press device 38 at a temperature at which a predetermined lenticular continuous pattern composed of convex lenticular protrusions 14 formed on the sheet surface of the transparent resin sheet 13 is not crushed. Will be done.

The decorative sheet 12 (12A) thermocompression-bonded by the thermocompression-bonding roll 39 of the hot-pressing apparatus 38 is subsequently guided by the after-heat-cooling apparatus 40 and post-heated at about several tens of degrees to 170 ° C. to enhance the adhesive effect. On the other hand, it is cooled by a cooling air of about 0 ° C. to several tens of degrees Celsius, and the transparent resin sheet 13 attached on the decorative sheet 12 (12A) is prevented from settling.

Further, the decorative sheet 12 (12A) is cooled by the cooling air in the afterheat / cool device 40, and if necessary, a method of performing natural cooling after cooling by the afterheat / cool device 40 or cooling by the afterheat / cool device 40 is performed. Alternatively, the decorative sheet 12 (12A) may be cooled only by natural cooling.

The decorative sheet 12 (12A) that has been post-heated or cooled by the afterheat / cool device 40 is naturally cooled while being deposited or installed on the stacker 41. The decorative sheet 12 (12A) provided on the stacker 41 has the configuration shown in FIG. The decorative sheet 12 (12A) may be a container body 10 (10A) of a metal container instead of a plate shape.

The decorative sheet 12 (12A) is used as a painting, a calendar, a signboard, and a guide plate (display plate) in its original shape, while it is further subjected to secondary machining to form a can container or a storage box. , Can manufacture final products such as electrical products.

FIG. 5 shows an example in which the transparent resin sheet 13 of the decorative sheet 12 (12A) is composed of a single layer. However, as shown in FIG. 10, the decorative sheet 44A has the transparent resin sheet 13 and the laminated sheet 45. It may be a laminated structure in which they are overlapped.
FIG. 10 shows a first modification of the decorative sheet 44A having a laminated structure.

The decorative sheet 44A has, for example, a laminated structure in which a transparent resin sheet 13 made of a synthetic resin material and a laminated sheet 45 are laminated, and, for example, a dot pattern 46 is printed between the sheets 13 and 45.

The transparent resin sheet 13 forms a turtle-shaped or lattice-like uneven pattern of lenticular continuous patterns on the surface of the sheet with a standard number of screen lines in which a large number of convex lenticular projections 14 are continuous, while the front surface of the sheet is back. The decorative pattern and the dot pattern 46 having the same standard screen number as the above are printed with a slight deviation in the axial direction.

Then, a transparent laminated sheet 45 is further laminated and attached to the back surface side of the transparent resin sheet 13 to form a decorative sheet 44A having a laminated structure, and then the decorative sheet 44A is printed on the container body 11 (11A). The decorative sheet 44A is formed by adhering to the surface of the metal plate 29 with an adhesive or an adhesive and integrating them.

The laminated sheet 45 may have a thickness that allows the relative positional relationship to change with the printing layer 30 formed on the surface of the metal plate 29, and the material thereof is the same as that of the transparent resin sheet 13. , A transparent material that transmits light may be used. For example, a synthetic resin sheet such as polyethylene, polypropylene, polyester, nylon, urethane, or polyvinyl chloride is used, and a polyester (PET) sheet is used from the viewpoint of environmental friendliness. An acrylic sheet is preferably used from the viewpoint of the above, and a soft vinyl chloride sheet is preferably used from the viewpoint of flexibility.
In the decorative sheet 44A, for example, the dot pattern 46 printed on the surface side of the transparent resin sheet 13 may or may not be visible depending on the viewing angle.

The print layer 30 can be visually recognized through the laminated sheet 45 in the portion where the dot pattern 46 cannot be visually recognized, and further, since the laminated sheet 45 has a predetermined thickness, the dot pattern 46 and the print layer 30 overlap each other depending on the viewing angle. The dot pattern 46 appears to move on the print layer 30. That is, in the decorative sheet 44A, each dot pattern 46 changes depending on the viewing angle, a three-dimensional pattern having a three-dimensional effect can be obtained, and decorative printing with excellent decorativeness can be obtained.
FIG. 11 shows a second modification of the decorative sheet 44B.

Similar to the decorative sheet 44A shown in FIG. 10, the decorative sheet 44B has a laminated structure, and the transparent resin sheet 13 and the laminated sheet 45 are laminated.

On the sheet surface of the transparent resin sheet 13, a large number of convex lens-shaped protrusions 14 are provided in a predetermined pattern in a grid pattern or a hexagonal pattern with a standard screen number, and the sheet back surface has a standard screen number as well as the sheet surface. Decorative pattern 46 For example, a dot pattern is printed with a slight deviation in the axial direction or the rotational direction.

Then, a transparent laminated sheet 45 is further attached to the back surface side of the transparent resin sheet 13, and the back surface side of the laminated sheet 45 is adhered to the front surface side of the printed metal plate 29 via an adhesive 15 to be integrally formed. Join to. In this case, a dot pattern, which is a decorative pattern 47 similar to the dot pattern 46 on the back surface of the sheet, is printed on the front surface side of the printed metal plate 29. The dot pattern 47 has the same or different screen lines as the standard screen lines.

In the decorative sheet 44B shown in FIG. 11, when the viewing angle is continuously changed, the dot patterns 46 and 47 appear to change with respect to the protrusions 14 due to the lens effect. The dot patterns 46 and 47 are made more complicated because the relative positional relationship between the dot pattern 46 and the dot pattern 47 can be continuously changed and visually recognized from the relative relationship between the thickness of the laminated sheet 45 and the number of screen lines. It is possible to obtain a decorative sheet 44B having excellent decorativeness that can be seen as a three-dimensional pattern.
FIG. 12 shows a third modification of the decorative sheet 44C.

The decorative sheet 44C is formed from the transparent resin sheet 13 and the laminated sheet 45 into a laminated structure. Then, a large number of convex lens-shaped protrusions 14 are provided on the sheet surface of the transparent resin sheet 13 in a hexagonal shape or a grid pattern with a standard number of screen lines, and a transparent printing layer 48 is provided on the back surface of the sheet.

Further, a transparent laminated sheet 45 is attached to the back surface side of the transparent resin sheet 13, and the transparent resin sheet 13 having a laminated structure is placed on the surface of the printed metal plate 29 via an adhesive 15 or an adhesive. It is attached and joined integrally to form a decorative sheet 44C. The surface of the metal plate 29 is a dot pattern 47 printed with the same or different screen lines as the standard screen lines of the protrusions 14.

In this decorative sheet 44C, the dot pattern 47 may or may not be visible depending on the viewing angle, but since the dot pattern 47 can be confirmed through the transparent print layer 48, the dot pattern 47 can be visually recognized in the portion where the dot pattern 47 can be visually recognized. The color of the transparent print layer 48 and the color of the dot pattern 47 are mixed, and the color of the transparent print layer 48 can be visually recognized in the portion where the dot pattern 47 cannot be visually recognized.

Further, since the laminated sheet 45 has a predetermined thickness, the overlapping positions of the dot pattern 47 and the print layer 48 can be displaced depending on the viewing angle to give a three-dimensional effect, and the dot pattern 47 moves on the print layer 48. It looks like this. That is, it is possible to see the mixed color portion move while changing the color of the transparent print layer 48 depending on the viewing angle, and it is possible to obtain a decorative sheet 44C having a three-dimensional pattern having excellent decorativeness.

Although FIGS. 10 to 12 show an example in which the decorative sheets 44A to 44C are configured in a two-layer laminated structure, the decorative sheets 44A to 44C may have a laminated structure of three or more layers. Even if the decorative sheets 44A to 44C have a laminated structure, when the transparent resin sheet 13 and the laminated sheet 45 are made of the same resin material, the joint surfaces are joined and integrated, so that the joint surface of the laminated structure is integrated. It is difficult to visually recognize or confirm.

In order to efficiently wind the decorative sheet 12 (12A) around the body material 65, the decorative sheet 12 (12A) is a dance object having a required length according to the length around the outer circumference of the body material 65. The sheet) is cut into a decorative sheet 12 (12A). The decorative sheet 12 (12A) is wrapped around a square tubular or block-shaped (box-shaped) body material 65 and attached to the decorative sheet 12 (12A), similarly to the decorative sheet wrapped around the cylindrical or sleeve-shaped body material 55.

The square tubular body material 65 is subsequently flanged to form an outer peripheral flange 68 on one side and an inner flange 74 on the other side, as shown in FIG. A press-molded bottom lid 69 is superposed on the outer peripheral flange 68 and integrated by winding.

The inner peripheral flange 74 formed on the other side of the square tubular body material 65 is internally wound by curling, and is projected over the entire circumference by squeezing to form a step portion 70 in the circumferential direction. , The body 71 of the can container 51b is configured.

The step portion 70 in the circumferential direction enhances the mechanical and physical strength of the mouth portion side of the can container 51. The step portion 70 in the circumferential direction has a stopper function for the upper lids 52a and 52b.
The lids 52 (52a, 52b) shown in FIG. 13 are attached to the mouth side of the can container 51 so as to be openable and closable.

The upper lid 52a of FIG. 13 is detachably covered on the body 71 of the can container 51 produced in the manufacturing process of FIG. 15, and the can container 51 with a lid shown in FIG. 16 is manufactured. At that time, a bottom lid 69 is used for the bottom of the can container 51. The bottom lid 69 is formed by pressing a metal plate.

In this way, the decorative sheet 50 attached to the plate-shaped metal plate 29 is sequentially pressed, curled, bent, etc., or made into a cylindrical body material 55 or a square cylinder body material 65. The lid 52a (52b) and the body portions 62, 71 of the can container 51 can be molded by the decorative sheet 12 (12A) wrapped and attached. By this molding process, can containers 51 (51a, 51b) having a three-dimensional pattern printed on the outer surface are manufactured. Since the can container 51 can improve the decorativeness of the outer surface, it becomes a can container with a large added value, and can bring out a three-dimensional effect and a high-class feeling.

In FIGS. 14 and 15, the metal plate 29 to which the decorative sheet 12 (12A) having a laminated structure is attached is subjected to machining such as corner cutting, rolling, and square folding, and the decorative sheet 12 (12A) is placed in the can container 51. An example was shown in which the container 10 (10A) of the decorative sheet 12 (12A) was formed by wrapping it around the body portions 55, 62, 71 and attaching it. The container 10 of the decorative sheet 12 can be applied to electric appliances such as thermos bottles, electric rice cookers, refrigerators, and washing machines instead of can products.

For example, a decorative sheet may be wrapped around the body of a thermos bottle and attached to the body to form a container for a three-dimensional decoration having a three-dimensional pattern on the body. Further, a decorative sheet of a transparent resin film having a lens effect may be wound around the bottle container and integrally joined to form a container for a three-dimensional decoration.

Further, while printing the required printing pattern on the surface of the metal plate constituting the container body with a plurality of screen lines, a decorative sheet is attached to the surface of the metal plate and integrally joined to the sheet surface of the decorative sheet. By utilizing and utilizing the lens effect of the formed standard screen number of lines, it is possible to stably and smoothly create a three-dimensional pattern having a three-dimensional effect on the surface of a metal plate. The metal plate is machined to form a continuous lenticular pattern on the surface of the decorative sheet. By three-dimensionally processing, a container for three-dimensional decoration can be created.

In addition, the decorative sheet is wrapped around the container body without crushing the decorative printed surface of the required printing pattern applied to the metal plate, and molded or machined into the desired shape to create a step at the seam of the decorative sheet. The added value of container products can be increased by forming and integrating non-stepped joints.
