TECHNICAL FIELD The present invention relates to a braille mount, more specifically, to a braille mount using a paper substrate. A mount with a shrink film using this mount with Braille is also referred to.

In order to improve the convenience of visually impaired people, Braille has been added to product packaging.
Patent Literature 1 describes providing braille on a blister container in which a lid member and a container member having a content storage portion are detachably adhered to each other at a peripheral thermal adhesive portion. Both the lid member and the container member are made of synthetic resin sheets.

Japanese Patent No. 4202808

From the viewpoint of reducing the burden on the environment, efforts are being made to reduce the amount of plastic used in packaging. As an alternative to packaging materials such as the above-mentioned blister containers, mounts with shrink films, in which cylindrical shrink films are adhered to mounts using a paper substrate, are expected.

In the case of providing Braille characters on the backing paper with the shrink film, it is impossible to provide Braille characters on the shrink film, so they must be provided on the backing paper. As a result of further studies, the inventor found several problems in providing Braille characters on a mount using a paper base material, details of which will be described later.
The inventor solved this problem and completed the present invention.

An object of the present invention is to provide a braille mount on which braille is preferably formed while using a paper substrate.

A first aspect of the present invention comprises a paper substrate layer, a resin layer provided on the paper substrate layer, a printing layer provided on the resin layer, and a varnish layer provided on the printing layer. The braille mount includes a braille portion having one or more braille characters protruding toward the varnish layer, and a portion of the paper base layer corresponding to the braille characters is recessed toward the varnish layer.

A second aspect of the present invention is a mount with a shrink film comprising the mount with braille according to the first embodiment and a tubular shrink film bonded to a portion of the mount with braille where no braille part is provided. .

According to the present invention, it is possible to provide a mount with Braille on which Braille is suitably formed while using a paper substrate.

FIG. 2 is a schematic cross-sectional view taken along line II of FIG. 1; FIG. 11 is a schematic plan view showing a braille mount according to a modified example of the present invention. FIG. 4 is a schematic cross-sectional view taken along line II-II of FIG. 3;

One embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG.
FIG. 1 is a schematic plan view showing a mount 1 with a shrink film according to this embodiment. The mount 1 with a shrink film includes a mount 10 with braille on which braille is formed and a cylindrical shrink film 30 joined to the upper surface of the mount with braille 10. - 特許庁

FIG. 2 shows the layer structure of the mount 10 with braille. The mount 10 with braille has a structure in which a resin film layer (resin layer) 12, an aluminum layer (hiding layer) 13, a printed layer 14, and a varnish layer 15 are arranged on a paper base layer 11 in this order.
In this embodiment, the paper substrate layer 11 and the resin film layer 12 are joined by the adhesive layer 21, and the print layer is formed on the anchor coat layer 22 formed on the aluminum layer 13. The adhesive layer 21 and the anchor coat layer 22 are arbitrary structures and may not necessarily be provided.

Materials for the paper base layer 11 include paperboard processed paper, coated cardboard, uncoated cardboard, special paperboard (coated cardboard, single-sided coated cardboard), paperboard processed paper (foil paperboard, impregnated paperboard, laminated paperboard, surface paperboard), microflute, base paper for cups, base paper for milk, special paperboard, ivory, water-resistant paper, and abrasion-resistant paper, among which card paper and surface-treated paperboard are preferred.
The thickness of the paper base layer 11 can be about 150 μm to 1500 μm, preferably 350 μm to 600 μm.

As the resin film layer 12, various known synthetic resin films such as polypropylene, polyethylene, and polyethylene terephthalate (PET) can be used. Among them, polyethylene terephthalate is preferable.
The resin film layer 12 and the aluminum layer can be easily formed on the paper base layer 11 by pasting a resin film having an aluminum foil or an aluminum deposition layer on one side thereof to the paper base layer 11 with an adhesive. 13 can be formed. In this case, as shown in FIG. 2, an adhesive layer 21 is interposed between the paper base layer 11 and the resin film layer 12 .

The sum of the thicknesses of the resin film layer 12 and the aluminum layer 13 is preferably 10 μm or more and 30 μm or less. If it is too thin, it is difficult to obtain the effect of holding the formed braille (details will be described later).
The thickness of the aluminum layer 13 can be 300 angstroms (Å) or more and 1000 Å or less, and may be 350 Å or more and 500 Å or less.

The printing layer 14 imparts characters, patterns, and the like to the mount 10 with braille. The print layer 14 can be formed using various known inks. The anchor coat layer 22 can be provided as necessary in cases such as when it is difficult for ink to adhere to the masking layer such as the aluminum layer 13 .
When only characters or patterns are formed on the printed layer 14, the concealing layer becomes the ground color of the surface of the mount with braille. For example, in the present embodiment, by providing the aluminum layer 13 as the concealing layer, the ground color of the surface of the mount with Braille characters is glossy silver. If the appearance of the masking layer is not to be used as the base color of the surface of the mount with braille, first, a full-surface printing layer is formed on the masking layer, and letters, patterns, etc. are printed thereon. By forming a transparent full-surface printed layer, it is possible to change only the color while utilizing the glossiness of the concealing layer. By forming an opaque full-surface printing layer, the background color can be freely selected without being affected by the masking layer.

The varnish layer 15 covers and protects the printing layer 14 . Various known varnishes, such as water-based varnish, oil-based varnish, and UV-curable varnish, can be used as the varnish layer 15, and UV-curable varnish is particularly suitable.
The thickness of the varnish layer 15 varies depending on the type of varnish used, but can be about 0.6 μm to 2.9 μm, preferably 2.3 μm to 2.7 μm.

As shown in FIG. 1 , the braille-bearing mount 10 has a braille part 2 having one or more braille characters protruding upward, that is, toward the varnish layer 15 , in a partial area. The content of the information indicated by the braille part 2 can be appropriately set according to the article to be packaged.

The braille part 2 can be preferably formed by embossing the backing paper having the layer structure described above. That is, the braille part 2 can be formed by sandwiching a base paper between a male mold having convex parts corresponding to the braille to be formed and a female mold having concave parts corresponding to the braille to be formed and applying pressure. As shown in FIG. 2, the paper base material layer 11 is formed with recesses facing the varnish layer by the foil stamping at the portions corresponding to the Braille characters.
Even if braille is formed only on the paper base layer by such foil stamping, the braille part easily returns to a nearly flat state. Since the resin film layer 12 is harder than the paper base layer 11, the shape of the Braille portion 2 is favorably maintained even against the action of external force generated after processing. Similarly, since the aluminum layer 13 is also harder than the paper base layer 11, it preferably retains the shape of the braille portion 2 after braille formation.

The inventor, while studying a suitable configuration of the mount with braille, found that the appearance of the braille part was often damaged after the foil stamping process. Deterioration in appearance can occur as tears or cracks on the surface of the paper substrate layer. The deterioration of the appearance is mainly caused by the deformation of the paper base layer due to the foil stamping process. The main reason was that Therefore, it has been difficult to eliminate this problem by changing the material and thickness of the paper substrate layer.

The inventor solved this problem by providing a masking layer on the paper base layer. In other words, by making the deterioration of the appearance of the paper substrate layer, which is difficult to completely eliminate structurally, by making it difficult to see with the concealing layer, a good appearance can be obtained even if the braille is formed by foil stamping while using the paper substrate. We realized a mount with Braille that can be held. Since the concealing layer is an opaque or low-transparency layer, even if the surface of the paper base layer is torn or cracked, deterioration of the appearance is hardly visible when viewed from the varnish layer side.

As described above, the braille mount 10 of the present embodiment preferably retains the braille formed by foil stamping, and suppresses deterioration of the appearance due to foil stamping.

In this embodiment, the material of the masking layer is not limited to the above-described aluminum, and other metals, synthetic resins, and the like can also be used. For example, an ink layer formed with an ink containing a binder resin such as silica may be used as the concealing layer, or a colored resin film with low transparency may be used as both the resin film layer and the concealing layer. The masking layer may be composed of a plurality of layers, and the materials of the layers may be different. Examples of metals other than aluminum include iron, copper, and gold.

An adhesive (symbol Ad shown in FIG. 1) is applied linearly or in a strip on the upper surface of the mount 10 with braille according to the present embodiment, and the outer surface of the cylindrical shrink film 30 is joined to complete the mount 1 with the shrink film. . When the article to be packaged is heated while being passed through the shrink film, the shrink film shrinks and the article is wrapped, and the article is held integrally with the mount 10 with braille, so that the article can be displayed.

When the mount with shrink film is manufactured by machine, it is assumed that pressure is applied to the mount with braille in the following steps, for example.
・Pressure due to the weight of a large number of braille backing papers stacked in the paper feed unit ・In the process of attaching a cut shrink film to the braille backing paper coated with adhesive, the braille backing paper passes between the drum and the rubber roller Pressure is applied when the shrink film is pasted ・The pressure bonding process between the backing paper with braille and the shrink film after pasting the shrink film ・The overlap detection process that is performed after the backing paper with the shrink film is completed and before it is stacked, it passes between the rollers All of the above-mentioned pressures act in a direction to bring the braille characters formed by foil stamping closer to a flat state. Since the protruding state of the part can be maintained, it is particularly excellent as a member of the backing paper with the shrink film.

Although one embodiment of the present invention has been described above, the specific configuration is not limited to this embodiment, and modifications and combinations of configurations are also included within the scope of the present invention. Some modifications are exemplified below, but not all of them, and other modifications are possible. Two or more of these changes may be appropriately combined.

A protective layer 40 may be provided to cover the braille portion 2, as in the modified braille mount 10A shown in FIGS. By providing the protective layer 40, the resistance to pressure and the like acting in the manufacturing process of the mount with the shrink film described above can be further enhanced, and cracks and peeling of the printed layer, varnish, etc. that occur during foil stamping can be made inconspicuous.
Examples of the material of the protective layer 40 include metal foil such as aluminum foil, and resin such as epoxy resin and urethane resin. When a resin is used as the protective layer, the protective layer can be formed by arranging a melted resin on the portion where the braille is formed. When a transparent resin is used as the protective layer, there is also the advantage that the pattern under the protective layer is not hidden. A coat layer may be further provided on the protective layer.

- The application target of the mount with braille according to the present invention is not limited to the mount with the shrink film described above, and can be widely applied to various packaging materials. Replacing the plastic member with the braille mount according to the present invention can contribute to reducing the amount of plastic used in the packaging material while ensuring good braille and appearance.

・In the shrink film attached to the backing paper with braille, the dimensions and the positional relationship with the backing paper with braille can be appropriately set according to the items to be packaged. In a plan view, the shrink film may be attached in a positional relationship such that a portion of the shrink film protrudes from the braille mount.
