DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper container provided with Braille display. More specifically, the present invention relates to a paper container having a function of preventing deformation and disappearance of Braille.

[0002]

2. Description of the Related Art As a method of processing Braille or the like, it is common practice to perform a convex embossing process on the surface of a base material by using an intaglio attached above (chess) and a relief plate attached below (face plate). The embossing is referred to as debossing in order to distinguish it from the case where a concave pattern is formed on the surface of the substrate by a convex shape above the base material and a concave shape below the base material.

Conventionally, as a container provided with a Braille display, for example, a container in which Braille is formed by debossing the surface of a wrapping paper box as described in JP-A-59-136777, No.-48439, a container in which Braille is formed by debossing on a resin laminating surface side of a base material in which a thermoplastic resin layer is laminated on one surface of a paper layer. Bulletin, Shokai 6
JP-A 1-122708, etc., a container in which an adhesive label formed with Braille is formed in a separate process and attached, a container as described in Japanese Utility Model Publication No. 1-131130. There is known a container in which Braille is integrally formed on a surface by forming a Braille pattern on a mold for forming the same.

[0004] In the case of a container to which an adhesive label formed with Braille is attached, it is necessary to prepare a Braille label in a separate process and attach it to the container, which increases the cost and is not suitable for mass production. There is a disadvantage that there is.

[0005] Further, in a container having Braille integrally formed on its surface, it is necessary to form Braille in a mold for molding the container, and various types of forming dies are prepared and prepared for each content to be packed. There is a disadvantage that the cost increases because of the necessity to keep it.

On the other hand, a paper material in which a thermoplastic resin is laminated on one surface of a paperboard or paper layer is used as a base material,
A method of forming Braille by debossing is known as a method of manufacturing a container having a low-cost Braille display that can be mass-produced.

[0007] However, a problem that has not been solved by any of the above-mentioned methods is that a paper container substrate provided with Braille display and a paper container formed from the paper container substrate protrude from the surface of the paper container. The convex part constituting Braille is directly subjected to external force under various circumstances encountered after forming and processing the container, and further after performing the convex part processing, and the convex part is crushed or shaved to produce Braille. There have been drawbacks such that the height which can be easily recognized cannot be maintained, and further, in some cases, the projections themselves are lost and cannot be realized as Braille characters.

[0008]

SUMMARY OF THE INVENTION An object of the present invention is to provide a paper container base material provided with a Braille display having a structure in which a braille composed of convex portions is formed by debossing, and a paper container base material formed from the paper container base material. A paper container equipped with a low-cost Braille display that can be mass-produced without being easily deformed under the various external forces encountered during and after the processing of the convex portion. Is to provide.

[0009]

According to the present invention, there is provided a paper container having a braille writing portion in at least a part of a paper container having a paper support as a base material, wherein the shape of the braille writing region is a region forming Braille. A paper container provided with a Braille display, characterized in that a portion other than the convex portion representing Braille is depressed in a concave shape from the surface of the paper layer.

[0010] Further, the present invention is characterized in that the method of forming a Braille display of the above-mentioned shape is performed only by compressing the base material from both front and back surfaces by using a debossed Braille depressed die and a debossed Braille debossed die. It is a paper container provided with.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1 is an enlarged view showing a cross section of a convex portion and a peripheral concave portion constituting Braille, FIG. 2 is an enlarged view showing a cross section of a Braille intaglio and a Braille convex plate used for forming the convex portion, and FIG. First
FIG. 4 is a plan view showing a punched blank of the first embodiment, FIG. 5 is a side view showing a second embodiment of the present invention, 1 is a convex portion, and 1a is Top, 2
Is a concave portion around the convex portion, 3 is an outer peripheral edge of the concave portion, 4 is a paper layer, 5 is a surface treatment layer, 6 is an intaglio plate for Braille, 7 is a relief plate for Braille, 8 is a front plate, 9 is a back plate, and 10a and 10b are side plates. , 11 is glue strip, 12a, 1
2b is a folded rule, 13 is Braille, and 14a, 14b, 14c, and 14d are Braille forming areas.

As shown in FIG. 1, the shape of the convex portion 1 constituting the Braille and the concave region 2 around the convex portion 1 is a truncated cone having a height of 0.3 to 0.5 mm and a diameter of 1.5 mm. Is set to The top 1a of the projection 1 is a flat portion having a diameter of about 1 mm. By making the shape of the convex portion 1 as described above, the moldability of the convex portion 1 to the base material by the deboss is improved, and the shape of the convex portion 1 when touched by a finger is maintained. The region of the concave portion 2 provided around the Braille 13 constituted by the convex portion 1 has a depth of 0.3 to 0.5 mm, and the outer peripheral edge 3 of the concave region 3
In order for the Braille 13 to be easily read by touching it with a finger, it is desirable to set the Braille at a position at least about 10 mm away from the Braille 13.

When the distance between the outer peripheral edge 3 of the recessed area 2 and the braille 13 is not sufficient, the angle of the outer peripheral edge 3 can be made gentle to make it easier to read the braille. In addition, depending on the conditions of the thickness, density, or various strengths of the base material, it can be dealt with by making the shape of the surface opposite to the surface on which Braille 13 is applied protrude as shown in FIG.

By setting the shape of the convex portion 1 and the peripheral concave portion 2 as described above, the surface of the base material displayed in Braille 13 is rubbed by another base material or the outer surface thereof,
Alternatively, even when the surface of the base material indicated by Braille 13 is subjected to an external force such as being pressed vertically by another base material or an outer surface thereof, the convex portion 1 forming the Braille 13 is not affected by the external force. The protrusion 1 is protected, and the formation of the protrusion 1 is maintained.

In the first embodiment of the present invention, as shown in FIGS. 1 and 3, the peripheral portion of the convex portion is depressed from the surface of the paper layer so that the convex portion protrudes from the surface of the paper layer. The paper container is a lower box-type paper container in which the height of the protruding portion itself is secured while avoiding it, and has a configuration in which a predetermined area of the back plate 9 of the paper container is indicated by Braille 13. In FIG. 3, Braille 13
Is displayed on the back plate 9, but the front plate 8 or the side plate 10 a may be provided with Braille 13 using Braille 13 except for the portions described later. The shape of the paper container is arbitrary,
It can be applied not only to the lower box type but also to any shape. In the case of this embodiment, the position at which the braille display is performed is arbitrary within the braille forming areas 14a, 14b, 14c, and 14d shown in FIG. 4, and the user can specify the position within a range that does not impair the design of the paper container. Although it is preferable to provide Braille 13 at a position where it is easy to detect, if Braille 13 is provided on fine explanatory characters or the like, the characters will be difficult to read, so it is better to avoid it.

As shown in FIG. 4, the blank blank of the first embodiment has a glue margin 11, a back plate 9, a side plate 10a and a front plate 8.
And the side plate 10b are connected to each other via folding lines, and the Braille forming region 14d of the back plate 9, the Braille forming region 14c of the side plate 10a, and the Braille forming region 14a of the front plate 8 are displayed in Braille 13. Is done. The braille forming areas 14a, 14b, 14c and 14d are the glue margin pieces 11 of the paper container in a tube-attached and folded state at least 5 mm inside the edge of the crease or blank.
Is set at a position at least 10 mm away from the peripheral edge.

The formation of Braille 13 by debossing is performed simultaneously in the step of punching a blank of a paper container. Therefore, due to the attachment of the Braille deboss type, the Braille is set to be at least 5 mm inside from the creases or the creases to be the edges of the blanks. You. The position set at least 10 mm away from the peripheral edge of the glue margin piece 11 in the folded and folded paper container is that the overlapping part of the glue margin piece 11 when the paper container is glued to the cylinder is the base of the paper container. Since the material is three layers including the glue margin piece 11,
This is because, when strongly pressurized, the base material may be crushed even if the projections 1 forming the Braille 13 do not protrude from the surface of the base material.

The second embodiment of the present invention, as shown in FIG.
The gable-top type liquid paper container with a spout has a structure in which the lower part of the side plate is indicated by Braille 13. When the contents are poured from the spout, the lower part of the side plate is grasped with a finger and lifted, so that it is easy to sense the display in Braille 13 at that time. In the case of a gable-top type liquid paper container, the display in Braille 13 is preferably provided on a side plate that is gripped by a finger orthogonal to a front plate provided with a spout. In the case of the liquid paper container of the above embodiment, the braille 13 can be formed on the roof portion. However, since the entire liquid paper container is shrink-wrapped after the contents are filled, the braille 13 is directly pointed on the shrink wrap. And it cannot be read unless the shrink wrap is removed, which is not preferable.

The substrate used as the paper container provided with the Braille display of the present invention is not limited at all, even if a thermoplastic resin or the like is laminated, or a metal foil is deposited or a metal foil is laminated. It can be used. However, the thickness of the substrate is 0.2 to
Desirably 0.7 mm.

The method for producing a paper container provided with a Braille display according to the present invention may be any one of printing, overcoating, extrusion lamination, etc., or a paperboard produced through a series of pre-processes depending on the use of the paper container. Braille 13 is formed on the base material by debossing at the same time as punching a predetermined paper container blank. The braille debossed plate concave mold 6 and the braille debossed plate convex mold 7 are attached to a punching machine, and the surface on the front side of the paperboard substrate, that is, the surface that faces outward when formed into a paper container, faces the concave side of the braille debossed plate. The braille 13 is debossed on the surface on the front side of the paperboard substrate by mounting and pressing. The blanks are then assembled to produce a paper container with a Braille display. At this point, the area where the Braille is formed is already under the protection of the concave portion 2 around the convex portion, so that it is not affected by the pressure during assembly.

As the Braille deboss plate concave mold 6, a deboss mold having a shape in which concave portions are formed in a matrix on the entire surface of the die, instead of forming concave portions at positions corresponding to the convex portions constituting Braille, is used. Can also. In that case, the debossed depressed mold 6 for braille can correspond to all braille.
Therefore, when forming various types of braille by debossing, braille debossing can be carried out only by replacing the debossed debossing mold 7 for braille, so that the preparation work for braille debossing is simplified and the debossed recessed mold is manufactured. Since costs can be reduced, costs can be reduced.

[0022]

According to the present invention, the peripheral portion of the projection forming the Braille is recessed from the surface of the paper layer so that the projection forming the Braille is prevented from protruding from the surface of the paper layer. By using a paper container that has the height of the protruding part itself that can be easily recognized, the surface of the base material or container on which Braille is given can be Even when rubbed or subjected to an external force such as the surface of the substrate or container on which Braille display is given is pressed in a vertical direction by another substrate or container or an outer surface thereof, the convex portion forming Braille Are protected from their external force and shape retention is maintained.
