[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention is an open-top cardboard case for storing small articles in a divided manner, and mainly relates to a case that is placed on a shelf or the like in a factory to store tools and machine parts.

[0002]

[Prior art]

 Conventionally, a rectangular metal or plastic box without a lid has been used as a case for storing tools and machine parts, but it is made of corrugated cardboard that can be incinerated inexpensively because it is expensive and can not be incinerated. A case is being considered. However, since the strength of a single case made of corrugated cardboard is small, the side plates in the longitudinal direction are easily bent and damaged, and even if the side plates have a double-folded structure, the stored items can be easily put in and taken out. If a slanted opening is formed at the front end, it is unsightly because the corrugated cardboard is exposed at the slanted opening, and the front end and the slanted opening are likely to be deformed because the front end is often pulled as a handle. To be done.

[0003]

[Problems to be solved by the device]

 In view of this, the present invention has a double-folded structure that is strong enough not to bend, and the corrugated cardboard is not exposed even if an inclined opening is formed at the front end so that it can be easily put in and taken out. It is intended to provide a cardboard storage case that can be rigid so as not to be deformed when held.

[Means for Solving the Problems]

 For this reason, the present invention is an open-top corrugated cardboard case for accommodating tools, machine parts, etc., and is connected to the respective outer edges of the bottom plate that are inclined at the front corners via folds. And an inner plate having an inclined corner portion facing the inclined corner portion of the outer plate on the front side is connected to the outer plate through a double crease fold, and an outer plate is formed at the widthwise rear end edge of the bottom plate. The outer backboards of approximately the same height are connected in series through the folds, and the inner backboard of approximately the same height as the outer backboards is also connected to the outer backboard through the double crease folds, and the bottom board The front outer plate, which is about half the height of the outer plate, is connected to the front end edge in the width direction of the through the creases, and the front inner plate having approximately the same height as the front outer plate is connected through the double crease folds. Front flaps are connected to each other, and rear flap pieces are connected to the rear edges of the outer boards through folds, respectively, and front flaps are inserted to almost half of the front edges of the outer boards on the bottom plate side through folds. A piece The inner plate is connected to the inclined corner portion of the front end of the outer plate via the inclined fold, and the inner folded piece is connected to the inclined corner portion of the inner plate via the inclined fold to form the bottom plate. Locking holes notched from the fold of the outer circumference to the inside are provided at the front and rear edges, the front parts of both end edges and the rear parts of both end edges, and used for locking the inner plate, inner back plate and front inner plate. An outer back plate and a front outer plate, which are formed by projecting projecting pieces, are bent up at the folds, and are erected inside the outer plate, and the inner plate is bent through the folded back inner piece Inside, the front flap piece and the rear flap piece are joined, and the inner back plate and the front inner plate are bent inward so that the inner plate, the inner back plate, and the front inner plate locking projections correspond to the bottom plate. The structure is formed by inserting into the stop hole. It should be noted that front flaps that overlap each other in the same shape as the front flaps of the adjacent outer plates may be connected to each other through the folds at the front edge of each of the inner plates. The flap piece may be provided with a locking groove that can be engaged with each other.

Since the front end corners of the inner plate and the outer plate are inclined corners, an inclined opening is formed at the front end so that stored items can be taken in and out smoothly, and the inner folding plate makes an incision at the inclined opening. Is not exposed, and a quadruple structure is formed by the interposition of the inwardly folded piece, which results in a solid inclined mouth. In addition, the front and rear parts are also quadruple-folded by flaps, resulting in a strong case overall and improved durability. Further, in the case where the front flaps are connected to the front edge of the inner plate, the double front flaps intervene with each other, and the front portion has a six-fold structure, which is extremely firm. Furthermore, since the inner wall surface is flush, the stored items can be smoothly taken in and out without being caught.
