BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a prefabricated paper box in which a box body and a lid can be assembled from a sheet of flat paper.

[0002]

2. Description of the Related Art Heretofore, there has been known an assembling type paper box in which a fold is provided on one sheet of flat paper and the box is assembled by bending from the fold. This conventional prefabricated paper box
The box body and lid can be assembled separately.

[0003]

When the box body and the lid are separately assembled as described above, it is necessary to prepare at least two paper patterns, which requires a lot of assembling man-hours. There were problems such as loss of raw paper. The present invention is intended to solve the above problems.

[0004]

In order to achieve the above object, the present invention provides a prefabricated paper box in which a fold line is provided on a sheet of flat paper, and the fold line is bent to assemble the box. For flat paper, the box body 2 and the lid 3
Are continuously provided via the lid bending line 4, and four box-side frames 2a and three lid-side frames 3a are provided on the outer peripheries of the box body 2 and the lid 3 via folds 2b and 3b, respectively. Bending corners formed by corner folds 2c and 3c and corners 2d and 3d that are provided and combined in the same pattern at the four corners of the four box-side frames 2a and the two corners of the three lid-side frames 3a. And the folds 2e, 3e of the ear pieces, the folded ear pieces 2f, 3f,
Providing a built-in ear piece composed of presser ear pieces 2g, 3g, sliding contact edges 2h, 3h, and bending lines 2i, 3i of the ear piece, and inserting the built-in ear piece into a bent corner to assemble the box body and the lid. It is characterized by having done.

[0005]

With the above construction, the prefabricated paper box of the present invention has one
The box body and the lid are assembled from a sheet of flat paper, which reduces the number of assembly steps and the loss of raw paper.Furthermore, the lid is integrally connected to the box body through the folding line. Since it has a lid, it does not lose its lid and is easy to use.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be specifically described below with reference to the accompanying drawings. In FIG. 1, reference numeral 1 is a pattern made of a slightly thick paper, in which a fold is provided on one sheet of flat paper, and the box is assembled by folding from this fold, which is formed by pressing. A box body 2 and a lid 3 are continuously provided on the flat pattern paper 1.
Four box-side frames 2a and three lid-side frames 3a are provided on the outer peripheries of the box body 2 and the lid 3 via folds 2b and 3b, respectively.

The above four box side frames 2a and three lid side frames 3a
Bent corner portions 2c, 3c, 2d, 3d, and built-in ear pieces 2e-2i, 3e-3i, which are adapted to be combined in the same pattern, are provided at the respective corner portions. Then, the box main body 2 and the lid 3 are assembled from one flat pattern paper 1.

That is, the bent corner portion is the corner fold 2
c, 3c and corners 2d, 3d. The built-in ear pieces include folds 2e and 3e, folded ear pieces 2f and 3f, presser ear pieces 2g and 3g, and presser ear piece 2
g, 3g, and slidable contact edges 2h, 3h formed at the tips of the g, 3g, and bending lines 2i, 3i of the ear piece. Reference numeral 4 is a fold line that folds the lid 3 toward the box body 2 side to open and close the box body 2.

When assembling a box from the template 1 having such a structure, first, from the state of FIG. 1 and FIG. 2A, four box side frames 2a and three lid sides are formed along the folds 2b and 3b. The frame 3a is bent inward to stand up. Next, when the box-side frame 2a and the three lid-side frames 3a are bent inward, the corners 2d and 3d are bent inward from the corner folds 2c and 3c as shown in FIG. , That fold 2
Make sure that c and 3c are on one side of the ear.

Then, the folding ear pieces 2f, 3f are bent inward from the folds 2e, 3e of the ear pieces, and the presser ear pieces 2g, 3 are formed.
While bending g inward from the bending lines 2i and 3i, the folding ear pieces 2f and 3f are inserted between the bent corner portions 2d and 3d and the box side frame 2a and the lid side frame 3a.
Attach the sliding contact edges 2h and 3h of the presser ear pieces 2g and 3g to the box side frame 2a,
When the sliding contact is made with the lid side frame 3a, the corner portions 2d and 3d are fixed by the pressing ear pieces 2g and 3g, and the box is assembled as shown in FIG. 2 (c) and FIG. To do. Then, the lid 3 is bent from the bending line 4 to open and close the box body 2.

[0011]

As described above, according to the assembling type paper box of the present invention, the following effects can be obtained. ． It can be assembled so that it can be fitted and removed from a single flat sheet of paper with the lid connected to the box body, and it can be easily assembled. ． Further, the same function as that obtained by separately assembling the box body and the lid can be obtained, and the number of assembling steps is reduced as compared with the case where the box body and the lid are separately assembled. ． Further, the pattern paper can be formed by one press, the loss of the raw paper is reduced, and the ease of use is good.
