Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to back-bound binding using a wire ring, and more particularly, to a case cover of ring-back bound binding.
[0002]
[Prior art]
Conventionally, in back-bound binding using a wire ring, a front cover part, a back cover part, and a cover back part are configured using a single cardboard, and three longitudinally extending pushes are provided on the back part of the cover. A so-called cut cover is also known. The cut cover is configured to open / close and rotate the front cover or the back cover by causing a fold to be intensively generated at the muscle pushing portion.
[0003]
[Problems to be solved by the invention]
However, in the conventional cut-off cover, it is difficult to concentrate the bend only on the struts because the entire cover is made of a single cardboard, and a large force acts when opening and closing the cover. The cover is easy to bend. In addition, when the cover is opened and closed repeatedly, there arises a problem that peeling or the like occurs inside the cover thick paper. For this reason, there is a problem that the text sheet cannot be sufficiently protected.
[0004]
In particular, with the above conventional cut cover, it is difficult to use the front cover or the back cover by moving the front cover or the back cover 360 degrees so that the front cover and the back cover overlap each other. The problem that occurred. For this reason, it must be used in a state where the front cover and the back cover are spread out, requiring a space that is almost twice as large as that of the text sheet, and it cannot be said that it is easy to use.
[0005]
Furthermore, the conventional bookbinding of the cut-off cover sheet has been evaluated as having a lower product value and technical value than so-called superior bookbinding because of the above-mentioned problems.

[0014]
In the present invention, a cover sheet is applied to the core paper on the back part of the front cover so that the core paper having a smaller hardness and / or thickness than the core paper on the front and back cover parts is applied, and the cover back part is set to be easily bent. As a result, smooth opening and closing movements of the front and back cover portions can be achieved, and damage to the cover can be prevented.
[0015]
As shown in FIG. 1 and FIG. 2, the case cover according to the present invention has a front cover part A, a back cover part B, and these cover parts A and B are engaged with each other so that they can be opened and closed at one edge. A cover back C is provided.
[0016]
A pair of ring through-hole rows extending opposite to each other in the longitudinal direction is formed on the cover back portion C, and a ring E is inserted into and supported by each ring through-hole 6. The ring E is inserted into the ring through hole 6 of the text sheet D, and the ring E separates the text sheet D into the front cover part A, the back cover part B, and the cover back part C. Can be held in.
[0017]
As shown in FIG. 7, the case cover is composed of core papers 2, 3, and 4 disposed inside each part, and the case cover is pasted on the surface of these core papers so that the core papers 2, 3, and 4 are integrated. A binding cloth 1 to be attached to the cover, and a payback 4 attached to almost the entire back surface of each part of the cover.
[0018]
In the embodiment, the core papers 2 and 3 used for the front cover part A and the back cover part B are formed by cutting 88 kg of chip cardboard L size manufactured by Jujo Paperboard Co., Ltd. into a size of 342 mm × width 255 mm. As the core paper 4 on the back part C of the cover, 130 kg of fancy paper Miyagi-no-sushi made by Tokushu Paper Co., Ltd. is cut into a size of 342 mm x 22 mm.
[0019]
The binding cloth 1 is also used by cutting 130 kg of fancy paper Miyagi-no-shiro 6 size, made by Tokushu Paper Co., Ltd., into a length of 374 mm and a width of 563 mm. Using glue as an adhesive, core papers 2 , 3, and 4 are hand-pasted and wrapped with a binding cloth 1 so that the surface is flush with the surface. 130 kg of fancy paper Miyagi-no-sushi made by Paper Manufacturing Co., Ltd. was cut into a vertical 332 mm × horizontal 523 mm and used as a reversal 5, and a reversing paste was applied to cover almost the entire back surface of the core paper 2, 3, 4 .
[0020]
By adopting the above configuration, it is possible to impart to the cover back portion C a strength that can sufficiently support the weight of the text sheet D applied to the ring E.
[0021]
In the embodiment, the core papers 2 and 3 of the front cover part A and the back cover part B are arranged with an interval of 23 mm, and the core paper for the cover back part C having a width of 22 mm is arranged between them. Apply the seal. In other words, only the cover sheets are arranged so as to create a gap of 0.5 mm between the arranged core papers.
[0022]
Theoretically, it is desirable that there are no gaps and the edges of the core papers 2, 3 and 4 are joined without gaps. However, in order to ensure the expansion and contraction of the paper material and the preliminary dimensions from the bookbinding operation, It is necessary to provide a gap.
[0023]
Each of the gaps is preferably within 1 mm, and if it is 1 mm or more, the cover may be distorted, and it is necessary to use a stronger material in return.
[0024]
The same material is used for the binding cloth 1, the core paper 4 on the back of the cover, and the facing 5, so it is convenient for the pasting of the cover because the material is the same. This is because the same color is obtained and a beautiful appearance is obtained.
[0025]
In the present embodiment, as described above, the hardness and thickness of the core paper 4 used for the cover back portion C are set smaller than the hardness and thickness of the core papers 2 and 3 used for the front and back cover portions A and B. are doing.
[0026]
The specific thickness and / or hardness of the front cover and back cover varies depending on the size of the cover, the width of the back of the cover, etc., but the extent that the cover does not bend when the cover is opened and closed If it is above, it is employable.
[0027]
As a result, a difference in rigidity occurs between the front and back cover parts A and B and the back part C of the cover, and when the cover parts A and B are opened and closed, the cover back part C bends easily and both cover parts A and B B can be smoothly opened and closed.
[0028]
Further, as shown in FIG. 8, a barb 7 extending in the longitudinal direction is formed in the center portion in the width direction of the back cover C. The muscle push 7 is configured by providing a concave line that is recessed inward. By providing the muscle push 7, the cover back portion C can be bent more easily, and the cover A and B can be smoothly opened and closed.
[0029]
In addition, it is also possible to use both the front and back covers A and B in a superposed manner by bending the front cover portion A or the back cover portion B 360 degrees with the muscle push 7 as the center. For this reason, it becomes possible to reduce the space at the time of use, and usability becomes much better.
[0030]
Therefore, in the bookbinding according to the present invention, it is necessary to provide a back-stiffening push for opening and closing the cover on the side edges of the front cover and back cover as in the case of upper bookbinding in normal bookbinding. Absent.
