Abstract

PROBLEM TO BE SOLVED: To easily build up a container such as a file box by one time of press work, and reduce the cost by a method wherein a front surface, a bottom surface, a rear surface and a pair of side surfaces which are connected with pressed ruled lines, are formed by one piece of a hard sheet, and to one part of the front surface, an extending surface including a combining part, is connected. SOLUTION: A black wherein a front surface 1, a bottom surface 2, a rear surface 3 and a pair of side surfaces 4 are connected with pressed ruled lines respectively, is formed of a hard sheet. Also, at both upper side parts of the front surface 1, a pair of extending surfaces 5 comprising a combining part 52 and an insertion part 53, are connected with pressed ruled lines, and at the same time, on both sides of the rear surface 3, a pair of incisions in the vertical direction, are provided. When this container is built up, after bending the front surface 1, the bottom surface 2 and the rear surface 3, the side surfaces 4 are bent, and side edge lower parts of the side surfaces 4 are bonded to the side edges of the front surfaces 1, and the end edges of the bottom surface 2 are bonded to the end edges of the side surfaces 4. Then, the combining part 52 is brought into contact with the side surfaces 4 by bending the extending surface 5, and the insertion parts 53 are bent and inserted in the incisions, and bonded on the internal surface of the rear surface 3.

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rigid sheet container. More specifically, a box file type that houses books, magazines, newspapers, etc. and is placed on a desk, etc., a document case type that houses and organizes or carries documents, or a small personal item such as a cosmetic or coin purse. TECHNICAL FIELD The present invention relates to a carry-bag-type hard sheet container in which a handle is added to a lid to be closed.

2. Description of the Related Art A conventional hard sheet container is formed by pressing a hard sheet into a predetermined shape, assembling the sheet, and then gluing necessary parts, fixing them with staples, or wrapping them with decorative paper and applying them. And completed as a container made of a rigid sheet.

As described above, the conventional hard sheet container requires a lot of trouble in the process of bonding, fixing with staples, or wrapping and pasting with decorative paper. A solution was desired.

According to the first aspect of the present invention, there is provided a hard sheet having a front surface, a bottom surface connected to the front surface via a pressing ruled line, a back surface connected to the bottom surface via a pressing ruled line, and a back surface connected via a pressing ruled line. It is composed of a pair of side surfaces connected to both sides of the front surface, a pair of extension surfaces are connected from both upper portions of the front surface via pressing ruled lines, and the extended surfaces are respectively connected and inserted portions via pressing ruled lines, and both sides of the back surface When the container is assembled by providing a pair of cuts in the vertical direction, the front, bottom, and back sides are folded 90 degrees each through the pressing ruled lines, and the side surfaces are bent 90 degrees each through the pressing ruled lines. The lower edge is adhered to the side edge of the surface, respectively, the edge of the bottom is brought into contact with the edge of the side, and the extended surface is bent 90 degrees through the pressing ruled line, and the joint is brought into contact with each side. The above problem was solved by bending the insertion portion 90 degrees through the pressing ruled line, penetrating the cut, and adhering to the inner surface of the back surface. The invention of claim 2 connects the upper surface from the upper edge of the back surface via a pressing ruled line, connects the lid surface to the upper surface via a pressing ruled line, provides a handhold near the upper surface at the center of the back surface, and the upper surface has a central portion. A narrow part, a slope part and a wide part are provided continuously at both ends of the narrow part, and the part is divided into three parts. A handbag hole is provided near the upper surface at the center of the lid surface to make a container material. The upper surface and the lid surface are each bent 90 degrees via the intermediary, and the lid surface is brought into contact with the surface, thereby enabling the invention of claim 1 to be applied to a carry-bag type rigid sheet container.

According to the present invention, it is possible to easily assemble a hard sheet into a container made of a hard sheet only by pressing one hard sheet once, so that it can be supplied at a low price.
