Description

The present invention relates to a paper sheet material that can be assembled into a box , its paper sheet material processing apparatus, and its paper sheet material processing method, and in particular, continuous concave portions are formed in a linear shape. The present invention relates to a paper sheet material having improved design properties, a paper sheet material processing apparatus, and a paper sheet material processing method.

  When the paper sheet material is processed, embossing is performed on the paper sheet material, so that a three-dimensional surface shape can be imparted to the paper sheet material and the design can be improved.

  As methods for imparting a three-dimensional surface shape of a paper sheet material, there are methods shown in Patent Document 1 and Patent Document 2.

  Patent Document 1 discloses a method for performing embossing using a rotary embossing unit. Patent Document 2 discloses a method for embossing using a male mold and a female mold.

  Embossing using a rotary embossing unit has a problem in that there is a limit in improving the positional accuracy of the applied embossing and printed pattern. In addition, the rotary embossing unit has a problem that the rotary roller is expensive and is not suitable for small-lot production. In addition, in order to change the three-dimensional surface shape by embossing, there is also a problem that it is necessary to replace the rotary roller, which takes time and effort.

  In addition, flat pressure embossing using male and female dies can be produced in small lots compared to the case of using a rotary roller, but the surface of the paper sheet material is relatively small. Suitable for embossing. For this reason, when embossing is performed on the entire surface of the paper sheet material, there is a problem in that the mold becomes large and the mold manufacturing cost increases. In order to change the three-dimensional surface shape by embossing, as with the rotary embossing unit, it is necessary to exchange the male and female molds, which takes time and effort.

  Therefore, there is a method disclosed in Patent Document 3 as a method for solving the above problems. In Patent Document 3, a concave portion is formed by pressing a sheet material, which is a material of a paper sheet material, with a ruled line member.

When the concave portion that is continuous on the surface of the paper sheet material is formed in a line shape by the ruled line member, it appears that a continuous seam is formed on the surface. However, the continuous formation state of shape and recessed portions of each of the recessed portions, so intends want becomes tends bent paper sheet along the concave portion continuously formed in a linear shape, design There is a problem that the strength and durability of the paper-made sheet material are lowered while the properties are lowered.

  Therefore, from the above points, the present invention improves the design, and the paper sheet material that can prevent the paper sheet material from being bent along the concave portions that are continuously formed in a linear shape, and the three-dimensional surface shape. A paper sheet material processing apparatus and a paper sheet material processing method capable of improving the positional accuracy of printing and printing, improving the processing efficiency, suppressing the cost, and easily changing the three-dimensional surface shape. For the purpose.

In order to solve the above-mentioned problems, the paper sheet material of claim 1 can be assembled into a box, and when the box is formed, a rectangular, rounded rectangle, or oval concave portion continuous on the outer surface is a line. In the paper sheet material formed in the shape, in the rectangle, rounded rectangle or oval, the ratio of the shorter width divided by the longer width is in the range of 1/5 to 4/5, A ratio obtained by dividing the shortest interval between the concave portions divided by the longer width is in a range of 1/5 to 1, and a groove portion for bending is formed in the paper sheet material, and the depth of the concave portion is bent. The ratio divided by the depth of the groove for use is in the range of 1/4 to 4/5 .

  According to the paper sheet material of claim 1, when the shape of the continuous concave portion is in the above range on the surface thereof, it becomes a pattern that seems to have a continuous seam formed on the surface, thereby improving the design. it can.

  When the width of the shorter concave portion is short, the wearing material is easily bent due to the concave portion. However, according to the paper sheet material of claim 1, in the rectangle, rounded rectangle or oval, the ratio of the shorter width divided by the longer width is in the range of 1/5 to 4/5. As a result, the width of the shorter side of the concave portion can be sufficiently ensured, so that the shape stability of the concave portion is improved, and the paper sheet material is not easily bent due to the concave portion.

  In addition, when the shape of the continuous concave portion is smaller than the above range, since the leading edge of the folds once generated easily progresses one after another through the continuous concave portion, the paper sheet is continuously formed along the linearly formed concave portion. The material is easy to bend. However, if the shape of the continuous concave portion is within the above range, the paper sheet material can be prevented from being bent along the concave portion that is continuously formed in a linear shape.

  Further, according to the paper sheet material of the first aspect, the depth of the concave portion is sufficiently shorter than the depth of the folding groove portion, so that the paper sheet material is easily bent at the folding groove portion from the concave portion. Therefore, when assembling a paper sheet material into a box, the paper sheet material bends along the recesses that are continuously formed in a line instead of bending the paper sheet material at the folding groove. It is possible to suppress the occurrence of malfunctions that occur.

  In the paper sheet material of claim 2, the ratio of the depth of the recesses divided by the thickness of the paper sheet material in the paper sheet material of claim 1 is in the range of 1/5 to 3/5.
