[Prior art]

 Conventionally, as a makeup box by this type of folding box, for example, there is one described in Japanese Utility Model Publication No. 57-3938. This conventional technique is made by punching from a piece of cardboard, and a side plate of the same width is continuously connected to each side of the bottom plate of a quadrilateral shape via a fold line, and one set of the side plates facing each other. A middle plate is connected to one side plate through a folding line, a lid plate is connected to the other side plate through a folding line, and a bending piece is connected to the other pair of opposite side plates through a folding line. The folding pieces are formed on the outside of these bent pieces through the folding lines, and the folding pieces are formed on the outside of the middle plate through the folding lines, and the middle board is formed by the perforations at the center. Side-symmetrical side pieces are formed on the side pieces.A long cut is formed in the side piece in the vicinity of the perforation and in parallel therewith, and a pair of arc-shaped cuts continuous from this cut and a parallel cut. A semicircular bent piece that is composed of a short fold line is formed symmetrically, and A notch of a certain length is formed near the edge so as to enclose the upper and lower edges of the perforation across the side piece, and the upper side edge of the middle plate is a triangle with the short side of the side as the base. A folding piece of a shape is projected through a fold line, and a bending piece having the same width as the side plate is continuously connected to the outer edge of the lid plate through the fold line, and a folding line is formed at the center of the outer edge of the bending piece. A tongue piece to be inserted into the notch formed at the center of the fold line is protruded through, and between the side plates, right-angled triangular fold pieces each having a side of each side plate are formed. The center of the hypotenuse of each folding piece and the corners of the bottom plate are connected by perforations.In the assembled state, the bottom plate is formed by bending the folding piece from the perforations. Bend in the direction, insert the triangular folds between the folded folds and the side plate, and fold Inserting the folding piece between the folding piece and the side plate, the middle plate is bent into a substantially V shape from the perforation, and the bending piece is pushed downward to form a storage space for the container to be contained.

[Problems to be solved by the device]

 The above-mentioned conventional technique has a good point that the stored object can be immovable by storing the stored object in the notched recess of the middle plate which is bent into a substantially V shape. Since the bent bottom is in contact with the upper surface of the lower plate, the impact applied to the lower plate is transmitted to the stored items as it is due to the rigidity of the intermediate plate, and there is no cushioning effect. Since a side plate having a complicated contour is required, the unfolding die becomes complicated and expensive, and folding and assembling is troublesome.

In order to eliminate the above-mentioned problems, the present invention floats and holds the lower part of a pair of slanting middle plates above the lower plate, thereby giving a cushioning effect to the stored object in the cut recess. The aim is to reduce the cost of the die and simplify the assembly by simplifying the development contour.

[0005]

[Means for Solving the Problems]

And the locking piece are successively connected, and a pair of middle plate and inner plate separated by an E-shaped cutting line through an inner folding line is provided on the outer side of the other side plate of the side plates. The side pieces and the folding pieces are sequentially connected to each other on the side edges of the middle plates on both sides of each of the middle plates through internal folding lines, and the opposite sides in the length direction of the respective side plates. The ear pieces are connected to each other via inner folding lines, and the middle plate is formed with a notch for accommodating an object to be stored to form a folding box deployment structure. All inwardly at the inner fold line and bring the above middle plates diagonally closer to the lower plate. In both cases, the lower plate and the middle plate side piece are fixed by pushing the above-mentioned folding piece between the ear piece and the top surface of the lower plate while pushing the inner surface of the middle plate side piece close to the ear piece of the side plate. The upper plate may be covered on the middle plate, and the outer plate may be engaged and locked to the edge cut of the lower plate by the locking piece.

[0006]

[Action]
