Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a case structure suitable for use as an outer case of various books (books) and CDs (compact disks).
[0002]
[Prior art]
In a conventional book case or the like, a simple case R in which a directly printed paperboard is assembled into a case shape as shown in FIG. 9 and a cardboard as a core are wrapped with printed thin paper so as to be bonded together. There is a luxurious case with a structure.
[0003]
However, in the case of the simple case R as shown in FIG. 9, since each of the peripheral edges RT of the insertion port Ra is made in a state where the end face of the paper is exposed as it is, the appearance of the appearance is not changed. When the book is put in and taken out, the edges RT are quickly damaged and weakened, and there is a problem that the shape is easily broken or torn and becomes dirty.
[0004]
Further, it has been considered that the case R itself is made strong to reinforce the peripheral edges RT. However, in order to make the case R strong, the paper thickness must be made thicker, which is very uneconomical. Further, there is also a problem that only the case R becomes thick and heavy, which makes various kinds of handling such as storage or transportation inconvenient.
[0005]
On the other hand, in the case of the above luxurious type case, since each peripheral edge RT of the insertion slot Ra is wrapped with printed thin paper, the appearance is good, and a book can be taken in and out without damaging the peripheral edge RT. Although it has the advantage that it can be performed smoothly, on the other hand, there has been a problem that the production cost is high because the work of laminating the core cardboard so as to be wrapped with printed thin paper is troublesome.
[0006]
Therefore, as seen in the application of Japanese Patent Application No. Hei 8-63747 (Japanese Patent Application Laid-Open No. 9-226269), the present applicant has turned back and forth side plates and upper and lower end plates constituting the insertion port respectively. We have developed a case for books and the like that has a luxurious appearance in which the edges of the insertion port are made of paper by folding these folded pieces inwards and bonding them together.
[0007]
FIG. 7 is an enlarged cross-sectional view showing the insertion portion of the book case or the like found in the above-mentioned application, and FIG. 8 is a cross-sectional view taken along the line XX of FIG. A and B are upper and lower side plates, C and H are end plates connected to one side of each of the side plates A and B, and D, E and G are respective end portions of the upper and lower side plates A and B and one end plate H. After the folded pieces D and E of the side plates A and B are folded at the folded edges Da and Ea, respectively, they are adhered to the inner surfaces of the side plates A and B, and are vertically overlapped. Of the end plates C and H, the folded piece G connected to the outer end plate H is folded at the folded edge Ga and adhered to the inner surface of the inner end plate C, so that the peripheral portion of the insertion port TX is formed. It is a mechanism that can be formed into a state just wrapped in paper.
[0008]
[Problems to be solved by the invention]
However, the conventional case for a book or the like constructed as described above is assembled into a box shape by laminating the inner and outer end face plates C and H, and finally, is folded back to be connected to the outer end face plate H. The piece G is folded back at the folded edge Ga so as to wrap around the opening edge of the inner end face plate C, and this is adhered to the inner side surface of the inner end face plate C. However, it is necessary to leave the bonding of this portion to a human, and as a result, there is a problem that the manufacturing cost (assembly cost) is increased.
[0009]
In addition, in the above-mentioned conventional case for a book or the like, the folded back piece G including the inner and outer end plates C and H is overlapped as shown in FIG. The portion becomes thicker than the edge portions of the upper and lower side plates A and B in which the two sheets are overlapped, the appearance is poor, and the edges of books and CDs are caught by the thick portion. There was also a problem that hindered access.
[0010]
Therefore, a technical problem of the present invention is to provide a case for books or the like having a luxury such that the periphery of the insertion port is wrapped with paper at a low cost by automatic molding by mechanical bonding. In addition, it is an object of the present invention to eliminate a portion in which three sheets are overlapped at the rim portion, to improve the appearance of the appearance, and to allow books and the like to be smoothly taken in and out.
