Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembling type back surface comprising two blanks used for packaging confectionery, towels / beddings, textiles, clothing accessories, miscellaneous goods and the like. The present invention relates to a curved book type case. 2. Description of the Related Art Conventionally, as an assembling-type paper box, a rectangular cylindrical type having a bottom and a lid having substantially the same structure as a tangerine box and having a single blank, and a lid and a main body as a caramel box. Is a type in which the lid is connected and covers one side of the lid, a type used for gift sets is separated from the main body and the lid is put on the main body, a hand-held type assembling paper box used for packaging of confectionery and the appearance is similar to a book Many types are known, such as book-type paper boxes. [0003] In recent years, book-type boxes have attracted particular attention because of their aesthetic appeal at the time of display and the novelty of structure. As a material used for such a book-type box, plastic, metal, and the like are used in addition to paper. On the other hand, as a method of manufacturing a box made of paper, a so-called Thompson type method in which printed paper is punched out according to a pattern by a machine and assembled is widely used. However, the shape of the paper box has to be limited to some extent due to the properties of the paper and the specialty of the manufacturing method based on the Thomson method. In particular, a part of the paper box is formed with a curved surface. It was difficult to do. Therefore, there is no paper box with the back surface of the book box formed into a curved surface like an actual book.To form the back surface of the book box with a curved surface, use plastic as the material and mold by using a mold etc. It had to be manufactured. It has been pointed out that such a box is more expensive than a paper box and is inferior in printability and transportability of the box alone. According to the present invention, the outer and inner blanks can be manufactured quickly and at low cost by using a Thomson type machine burr, and can be made flat when transported. In the form of a characteristic curve, the outer (outer box) and inner (inner box) are easily combined,
It is an object of the present invention to provide one strong back-curved book case. [0007] In order to solve the above-mentioned problems, according to the first aspect of the present invention, an insertion piece is formed at the tip.
Folding-back portion and a bottom plate provided with folded portions at both ends, the back plate,
Formed at the lower edge of the front plate of the inner box, and the outer box blank that successively connects the lid top plate, the lid back plate that is folded back and adhered to the lid front plate, and the inner box bottom plate that has insertion pieces formed at both ends. The insertion piece located at the end of the folded part connected to the bottom plate of the outer blank is engaged with the slit at the lower end of the front plate of the inner box, and the inner box bottom plate of the outer blank is engaged with the inner box. It is characterized by having done. [0008] With this configuration, when the two blanks are engaged with each other, the back plate of the outer box blank can be curved along with the arc-shaped protrusions formed on both ends of the rear plate of the inner box. Through a simple process, it is possible to assemble a book-shaped paper box having a curved back surface. In this case, by preparing the blank in the Thomson format, it is possible to finish the surface covering on the bottom plate surface, the back plate and the cover plate surface in one printing process. Printing method in this case is offset, hot stamping (foil stamping)
Etc. can be used. As the surface treatment, varnish, vinyl, press working, film sticking, mat vinyl, mat varnish and the like can be used. Further, as a material of the paper box, coated balls, card papers, ivory, cast coat, water- and oil-resistant papers, E-cardboard, F-cardboard, special paper for sticking boxes and the like are used. [0010] By adopting the above structure, the inner box and the outer box blank can be easily and firmly engaged with each other. That is, the position of the inner box is determined by inserting the insert of the blank for the outer box into the slit of the inner box, and then the back plate and the bottom plate of the inner box are covered with the bottom plate for the inner box, and the small slit at the lower end of the front plate of the inner box By inserting the tongue piece, the bonding strength between the inner box and the outer box blank can be increased. As a printing method in this case, there is the printing method described above. In particular, by printing on the surface of the bottom plate, the back plate, the cover top plate, as well as the surface of the cover back plate and the bottom plate for the inner box, a great deal of information can be published. An embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows an outer box blank of the present invention, which is formed by a coated ball.
