Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a packaging box for storing articles when carrying them.

[0002]

[Prior Art]

 It is generally known that when packing and packaging goods, they are packed so that the contents do not move during movement. In addition, even if they are simply displayed, food, containers, etc. are often held in a pattern and packed in a cosmetic box, so that the contents cannot be moved by a small impact. If the product has a rectangular shape, we prepare a wrapping paper or a specified box made of cardboard so that it can be easily packed.

On the other hand, it is space-consuming to assemble a plurality of cardboards in a box shape and prepare a plurality of them, so that a cardboard is used when assembled. For example, a structure in which four surfaces are cylindrical and half-assembled is flattened and the two surfaces are connected to both ends to form a box-like shape during assembly, or the cardboard 1 is molded as shown in FIG. In some cases, all six surfaces are formed during assembly. When assembling all six sides, all the folds 2 are valley-folded to form a box body, and the seam allowance 3 is housed inside the box body.

[0004]

[Problems to be solved by the device]

 However, if a square-shaped item (such as a glass case) is stored in the rectangular box as it is, the item will be easily broken due to an external collision, so the box will be doubled or stuffed for packing. The cost is high because it has to be done. Also, even if the one shown in FIG. 6 is assembled, it has a square shape and the shape of the box alone does not reduce the impact force. Therefore, it cannot be said that the contents are sufficiently protected against impact and the same as above. There is a problem that stuffing is required and workability is poor.

An object of the present invention is to provide a packaging box having a function of absorbing shock without assembling a box body by assembling a box body with one cardboard.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention has a box body formed by folding a cardboard, etc., and has four opposing sides, a connecting side surface, extending on four sides of the bottom surface. A substantially L-shaped seam allowance is provided together with the joint seam seam part, and the L-shaped bent part of the seam seam is valley-folded, and the boundary between the opposite side surface and the opposite seam margin is mountain-folded. The opposing side surface-side extending portion of the surface is characterized in that the connecting margin portion is extended.

[0007]

[Action]

 According to the present invention having the above-mentioned structure, the following series of movements are performed in association with each other by raising the opposite side surfaces. That is, the facing margin portion projects outward, the connecting side surface rises together with the joint margin portion, the joint margin portion abuts the margin portion, and the approximately L-shaped margin margin bend portion forms a valley fold, The boundary between the facing side surface and the facing margin is mountain-folded, and an angular buffering portion against the impact due to the L-shaped margin is formed at the outer corner of the box. Further, since the extending portion on the opposite side surface of the upper surface is formed by extending the connecting margin portion, the U-shaped buffer portions are formed on both sides of the box body.

[0008]

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. As shown in FIG. 1, the box body 4 in an assembled state has a corner cushioning portion 7 protruding from an end of the connecting side surface 6 and an extending portion 9 protruding from an upper surface 8 continuously around the opposite side surfaces 5 on both sides. It is formed on and protrudes like an eaves. The corner cushioning portion 7 is doubled due to the bent structure.

The box body 4 is assembled by a piece of thick paper 10 shown in FIG. The cardboard 10 is provided with facing side surfaces 5 and connecting side surfaces 6 facing each other on four sides of the bottom surface 11, and four margins 12 for aligning the edges of the facing side surfaces 5 and the connecting side surfaces 6 are provided. The facing margin portion 12a of the side surface 5 and the connecting margin portion 12b of the connecting side surface 6 are formed into an L-shape, and the bending portion 13 of the margin portion 12 is valley-folded. The boundary 14 between the facing side surface 5 and the facing margin 12a is mountain-folded. On the other hand, the upper surface 8 is formed by extending the connecting margin portion 12b to widen the width and forming extending portions 9 on both edges, and extending the entire upper surface to form the connecting side surface 6 and the insertion piece 15. A support surface 16 is formed at a position corresponding to the upper portion of the facing side surface 5, and a hole 17 for inserting the insertion piece 15 is formed at the end of the bottom surface 11.

The operation of the present embodiment thus configured will be described below. As shown in FIGS. 3 to 5, the box body 4 is assembled as follows. First, as shown in FIG. 2, when an article is placed on the bottom surface 11 of the cardboard 10 in an open state, and the two opposite side surfaces 5 are pushed inward so as to stand upright, as shown in FIG. Becomes a mountain fold and the bent portion 13 is made a valley fold, and the surfaces of the facing margin portion 12a and the joint margin portion 12b come close to each other, and the joint side surface 6 rises. Then, when the opposing side surface 5 is continuously erected, the (imaginary) edges of the opposing side surface 5 and the connecting side surface 6 are brought together as shown in FIG. 4, and the surfaces of the facing and overlapping margin portions 12a and 12b are joined together. Will come together. Next, as shown in FIG. 5, the upper surface 8 is bent, the lid is closed, and the insertion piece 15 is inserted into the hole 17, whereby the product is packaged and the outer shape of the box body 4 is as shown in FIG.

By erecting the facing side surface 5 in this manner, the facing margin portion 12a is projected outward by the above-described series of movements, and the joining margin portion 12b of the connecting side surface 6 is also raised up and connected. The seam allowance portion 12b and the opposing seam allowance portion 12a are combined, the substantially L-shaped seam allowance 12 is ejected to the outside, and the box body 4 is easily assembled. Moreover, the L-shaped seam allowance 12 forms the corner cushioning portion 7 against the impact at the outer corner portion of the box body 4. Further, since the opposing side surface extending portions 9 of the upper surface 8 are formed by extending the connecting margin portions 12b, the U-shaped cushioning portions are formed on both sides of the box body 4 as a whole. Become. Further, the corner cushioning portion 7 and the extending portion 9 support the box body by the U-shaped frame, so that a strong structure is obtained. Therefore, even if an obstacle hits the corner of the box 4 during transportation, the impact force is buffered by the buffer 7 and the extension 9, and the packaged product is protected. Further, since the impact force is buffered in this way, it is possible to directly insert the item into the box body 4 without filling it.

Further, as shown in FIG. 1, in the state where the box body 4 is assembled, the cushioning portion 7 has a double thick paper sheet, and the cushioning portion 7 at the portion where the connecting side surfaces 6 overlap has a triple thick paper sheet. Since the strength is stronger, the cushioning effect is improved and the packaged items are more reliably protected. Further, since the glue allowance 12 is ejected to the outside at the time of assembling, it is possible to wrap the product with the goods placed on the bottom surface 11 of the opened cardboard as shown in FIG.

[0013]

[Effect of the device]

 Since the present invention is configured as described above, it is possible to assemble a box body having a function of cushioning impact with only one piece of cardboard, and it is possible to assemble it without adding special work such as padding. Work becomes easy. In addition, since the margin portion protrudes to the outside, the product can be easily packaged, the box body is strengthened, deformation due to external force can be prevented, and the extension part or the like can protect the product from a collision object. it can.
