Description

[Detailed Description of the Invention] The present invention relates to an assembled paper box that can be used as a letter box, a bell box, a high-grade pencil case, a stamp box, a confectionery box, etc.

Conventionally, letter boxes, tin boxes, luxury pencil cases, stamp boxes, etc. have been made of lacquerware or wooden boxes with patterns on the surface, giving them a dignified quality and texture worthy of letter boxes, tin boxes, etc. Also, those made of bamboo and rattan have a unique texture that brings out the characteristics of the material. Recently, many products are made of synthetic resin and metal, but while these have the advantage of saving time and effort in manufacturing and are inexpensive, they have lost the characteristic features of traditional wooden and bamboo products. It ends up. By the way, there are wooden and bamboo letter boxes, tin boxes, high-quality pencil cases,
The solemn taste and unique texture of stamp boxes and the like lies in the characteristics of the material and the surface treatment, and among these surface treatments, it is important that the corners of the top and side panels of the lid are rounded. It has become a major element. This roundness can be easily achieved with synthetic resin or metal, but with wood or bamboo, it is not only difficult to make, but also expensive, making it a so-called luxury item.

Therefore, the purpose of the present invention is to provide an assembled paper box that can be easily manufactured without losing its original grandeur and texture by rounding the corners of a box made by assembling paper. .

In order to achieve this purpose, the present invention has side plates installed on each side of the top plate, and the mating edges of each side plate are slightly retracted from the extension line of the fold between the other side plate and the top plate. The mating edge formed therein has a diagonal notch at the fold point with the top plate, and each side plate is bent along the fold to bring the mating edges together. In addition, the peripheral edge of the top plate is rounded and bent, and the top plate corner portion is rounded and bent into the gap formed by the notch.

The present invention will be explained below using an example in which the present invention is used as a lid for a text box.

FIG. 1 is a developed plan view, in which side plates 2a, 2b, 2c, and 2d are successively provided on each side of a rectangular top plate 1, and these locations become folds 3a, 3b, 3c, and 3d. This is made by cutting cardboard or cardboard. And side plates 2a, 2b, 2c, 2d
The mating edges 4a, 4b, 4c, 4d at both ends of the mating edges 4a, 4b, 4c, 4d are the mating edges 4a, 4b, 4c, 4d that are mated to each other when the side plates 2a, 2b, 2c, 2d are bent.
The folds 3a, 3b, 3c, and 3d of the top plate 1 are slightly recessed from the extension lines of the folds 3a, 3b, 3c, and 3d. For example, as shown in FIG. 2, the mating edge 4a of the side plate 2a
It is slightly retracted from the extension line Eb of the fold 3b between the top plate 1 and the side plate 2a, and the mating edge 4b of the other side that meets when folded is also an extension line of the fold 3a between the top plate 1 and the side plate 2a.
Formed slightly more recessed than Ea. Also, Annex 5a,
The parts indicated by 5b, 5c, and 5d are the mating edges 4a, 4
At the mating edges near b, 4c, and 4d, the fold points of these mating edges 5a, 5b, 5c, and 5d with the top plate 1 correspond to the corner parts 1a, 1b, 1c, and 1d of the top plate 1. A diagonal notch 6... is provided.

In assembling the cardboard or corrugated paper cut as described above, first, the peripheral edge 7 of the top plate 1 is rounded using a mold such as a round bar as shown in FIG. Then, each side plate 2a, 2b, 2c, 2d is bent along the folds 3a, 3b, 3c, 3d, and the mating edges 4a and 4b, the mating edges 4b and 4c, the mating edges 4c and 4d, The mating edge 4d and the mating edge 4a
are fixed with cellophane tape or the like to form side joints 8a, 8b, 8c, and 8d. Next, the corner parts 1a, 1b, 1c, 1d of the top plate 1 are rounded and bent into the gaps formed by the notches 6... of the side joint parts 8a, 8b, 8c, 8d, and fit together. It constitutes the lid 9 of. Then, the required exterior paper, such as one with a grain pattern, a bamboo pattern, or one with a gloss and pattern similar to lacquerware, is covered and glued to finish the exterior. The lid 9 constructed in this way is placed over a main body 10 also made of cardboard or corrugated paper to form a text box as shown in FIG. 5.

In the above embodiment, the side joints 8a, 8b, 8
c and 8d are fixed with cellophane tape, but there may also be a configuration in which a glue margin is continuously provided on one of the mating edges and the adhesive is pasted using this glue margin. In addition, although the lid of the letter box was explained in the above example, there are other cases such as tin box, luxury pencil case, etc.
It may also be an assembled paper box that can be used as a stamp box, candy box, etc. Therefore, the planar shape is not limited to a rectangle, but may be changed as appropriate depending on the purpose. For example, a square, a hexagon, etc. Further, since the angle of the corner portion of the top plate changes depending on the planar shape, the size and shape of the corresponding notch portion 6 are also changed as appropriate. still,
The material used may be paper coated with a synthetic resin film or mixed with synthetic resin pieces.

As described above, the present invention is an assembled paper box used for letter boxes, tin boxes, luxury pencil cases, stamp boxes, confectionery boxes, etc., and has rounded corners on the top and side panels, similar to wooden boxes. Because of this, it is possible to create a majestic look and texture with paper that is worthy of use.
In addition, since it is an assembled paper box, it is easy to manufacture and inexpensive, and by appropriately selecting the pattern of the outer wrapping paper, it is possible to create the appearance of lacquerware, bamboo, rattan, etc.

In particular, when the paper is rounded, the paper does not stretch, so the linear length of each side of the top plate of the finished paper box becomes shorter by the amount of roundness compared to when it is unfolded. Therefore, if you connect side plates with the same length as the top plate when unfolding, the length of the side plates will be longer than each side of the top plate when assembled, so the mating edges of the side plates will meet each other at the side joints. It will disappear even more. The present invention solves this problem by making the mating edges that are matched with each other slightly retracted from the extension line of the fold between the opposing side panels and the top panel, thereby providing an assembled paper box that can be assembled without any trouble. Furthermore, since the corners of the top plate are rounded and fitted into the corresponding notches of the side plates, the corners of the top plate are also neatly arranged.
