Abstract

(57) [Summary] (with amendments) [Purpose] To improve safety by eliminating sharp corners of assembly-type packaging boxes. [Structure] A single plate-like sheet 3 cut into a predetermined shape is folded up and down, and the rising parts on both sides are made to stand up and assembled into a hollow box. A smooth curved edge 8 is attached to the extension of both ends, and after the box is assembled into a box shape, the curved edge 8 becomes the corner of the box and forms a rounded corner.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to an assembly type packaging box used for product packaging, particularly for individual packaging.

0002

[Conventional technology]

Traditionally, packaging boxes for products have been made of vinyl chloride or cardboard, as shown in Figure 5. Fold the sheet in half and raise the oblong anti-weight-shaped rising parts 6 attached to both side edges at right angles. A prefabricated packaging box that stands upright and forms a storage space for products between the upper and lower sheets 1 and 2 is well known. It is. When using this packaging box, it is sturdy and easy to assemble, and the sheet material By using a transparent vinyl chloride sheet, the contents can be seen through, making it easy to sell in stores. It is suitable as a packaging box for products to be sold.

0003

[Problem that the idea aims to solve]

However, with the above structure, the rising portions 6, 6 on both sides of the packaging box are horizontally long anti-weights. Because it is a shaped object, there are sharp points at both ends, i.e. at each corner of the packaging box. 1 will be formed, and there is a danger that this point 11 will damage other items. There is a risk of harm to the handler or the purchaser of the product, or even to the contrary, The problem is that when a product receives a shock from a product, it is crushed and the product value decreases. There is.

0004 The purpose of this project is to provide a safe assembly type packaging box that does not have sharp edges at each corner. It's about doing.

[0005]

[Means to solve the problem]

In order to achieve the above purpose, the assembled packaging box according to the present proposal is cut into a predetermined shape. Fold the cut plate-like sheet up and down, stand up the rising parts on both sides, and make it into a hollow box. A prefabricated packaging box that can be assembled, The rising parts on both sides are arc-shaped bends made on the upper and lower sheet surfaces of the assembly box. It is bent from a line, has a horizontally long anti-weight shape, and has an extension of both ends of the rising part. The seat surface has smooth curved edges, The curved edges form the corners of the assembled box.

[0006]

[Effect]

The curved edges attached to the sheet surface on the extensions of both ends of the rising parts forming a weight-proof shape are After the box is assembled, the curved edges will form the corners of the box, so they will not be pointed, but will have rounded corners. It becomes a stylish box, does not injure other items or the human body, and is protected from external shocks. The horns will not be crushed even when hit.

[0007]

【Example】

An embodiment of the present invention will be described below with reference to the drawings. Figure 1 shows the simplest assembly example. It shows. The assembled packaging box according to this proposal is a plate-like sheet cut into a predetermined shape. 3 is folded and assembled, and there are upper sheet 1, lower sheet 2, and risers on both sides. It is a hollow box having a section 3. The plate-like sheet 3 is a vinyl chloride sheet or cardboard. , transparent vinyl chloride sheet is suitable.

[0008] In this embodiment, a folding line 4 is attached to the center of the plate-like sheet 3 as shown in FIG. It is divided into a sheet 1 and a lower sheet 2, and has arcuate folding lines 5 on both sides of each part. A substantially rectangular sheet with a rising portion 6 integrally attached thereto is used. In addition, the edge of the upper sheet 1 A bent edge 7 is provided on the edge. However, the distinction between the upper sheet and lower sheet is explained below. This is for convenience, and after it is assembled into a packaging box, there is no substantial distinction between the top and bottom surfaces. There's no point.

[0009] In this proposal, both longitudinal ends of the anti-weight shape of the rising portion 6 and the upper sheet 1 or the lower sheet A smooth curved edge 8 is created by cutting out the sheet surface in an arc shape across the two sides of the seat 2. It is attached.

0010 When assembling into a box shape, fold the bent edges 7 inward and separate the upper sheet 1 and lower sheet 2. Fold them in half and stand up the rising parts 6, 6 on both sides of each sheet 1, 2, respectively. This results in a hollow box shape as shown in FIG. The rising part 6 on the upper seat side and the lower seat The side rising part 6 is overlapped inside and outside, and is formed on the seat surface on the extension of both ends of the rising part 6. The curved edge 8 is formed by the upper sheet side and the lower sheet side facing each other vertically, and The result is a packaging box with a rounded appearance.

[0011] After storing the contents, the packaging box according to the present invention is divided into the upper sheet 1 and the lower sheet as usual. The open edge with 2 and the rising portions 6, 6 are sealed using adhesive tape or the like.

0012 In the embodiments described above, the rising portions are provided separately on the upper sheet and the lower sheet. This example shows an example in which the inner and outer layers are overlapped to form a box shape. It may also be provided in series, interposed between the lower sheet and the lower sheet.

[0013] FIG. 3 shows a packaging box in which a rising portion 6a on one side is formed between an upper sheet 1 and a lower sheet 2. The developed view of FIG. 4 is an example in which the rising portions on both sides are formed between the upper sheet and the lower sheet. The configuration of such an assembly box is well known.

[0014] In the example shown in Fig. 3, the upper sheet 1 is stacked on the lower sheet 2, and the rising part between both sheets 1 and 2 is 6a, and stack the rising parts 6 and 6 on the other side inside and out, and The overlapping part and the opposing edges of the front and rear are sealed. Extension of rising parts 6 and 6a A curved edge 8 is attached to the upper seat surface.

[0015] Furthermore, in the example of FIG. 4, the folded sheets 9 attached to both sides of the lower sheet 2 are The rising portions 6b, 6b are formed between the lower sheet 2 and the pair of folded sheets 9, 9. The curved edges 8 are attached to both ends of the rising portions 6b, 6b. Insert The sheets 9, 9 are stacked on the lower sheet 2 and locked to each other, and the rising portions 6b, 6b are raised up. The cover sheet 10 is then placed on top of the cover sheet 10 to form a box-like structure. Both started up The curved edge 8 formed at both end extensions of the curved portion covers two sections of the upper sheet 1 or the lower sheet 2. When assembled into a box shape, this curved edge 8 becomes the box corner and the corners are rounded. It becomes a full box.

[0016]

[Effect of the idea]

As described above, in accordance with the present proposal, the anti-weight-shaped rising part is made to stand up and assembled into a packaging box. When the packaging box is stood upright, no sharp edges are formed at each corner, and the corners are rounded as a whole. It is a safe box that does not injure other items or the human body, and is Since the corners will not be crushed by impact, the product value will not be reduced. .
