Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a paper box having at least two middle boxes.

[0002]

2. Description of the Related Art Hitherto, a paper multiplex box has been composed of a plurality of middle boxes of the same size and an outer box in which these are simultaneously stored (hereinafter referred to as a paper box A). In addition, a multiplex box (hereinafter, referred to as a “multiple box”) including a plurality of middle boxes and an outer box storing the middle boxes in a drawer shape
Paper box B).

[0003]

However, in the paper box A, it is troublesome to take out and store the individual middle boxes. Further, in the drawer-type paper box B, taking out and storing are convenient, but the structure of the outer box is complicated and manufacturing is not easy. Further, when the drawers are pulled out, the respective inner boxes overlap. There was a problem that the contents could not be seen. The present invention has been made in view of such circumstances,
It is an object of the present invention to provide a paper box which is easy to manufacture and in which the contents of each of the inner boxes can be visually recognized in the opened state.

[0004]

According to the present invention, there is provided a paper box according to the present invention, comprising a first and a second middle box having a bottom plate and a side plate and having the same diameter in plan view. The first and second inner boxes arranged at the upper and lower two stages have first and second joints on the inner side where right and left side plates of the first and second inner boxes are respectively joined. A fold is formed in a longitudinal direction at an intermediate position in a circumferential direction of the second joint, and a cut is formed on a circumferentially outer side of the first and second joints. It has a lid that covers the top with the cylinder closed. Here, the paper box according to the present invention has the following aspects in detail. (1) The first and second middle boxes are circular in plan view, and may be square in some cases. (2) When the outer cylinder body is closed with the first and second middle boxes inside, the outer cylinder body has an overlapped portion at a cut portion. (3) The side plates of the first and second middle boxes and the outer cylinder are made of single-sided cardboard or cardboard in which a corrugated plate and a flat plate are joined.

BEST MODE FOR CARRYING OUT THE INVENTION

Next, embodiments of the present invention will be described with reference to the accompanying drawings to provide an understanding of the present invention. FIG. 1 is a perspective view of a paper box according to an embodiment of the present invention in an open state, FIG. 2 is a perspective view of the paper box in a closed state, and FIG. 3 is a longitudinal sectional view of the paper box. It is.

As shown in FIGS. 1 to 3, a paper box 10 according to an embodiment of the present invention has first and second middle boxes 11 and 12 of the same shape arranged in two upper and lower stages. It has an outer cylindrical body 13 that accommodates this inside and a lid 14. Hereinafter, these will be described in detail.

The first and second middle boxes 11 and 12 have circular bottom plates 15 and 16, respectively, and side plates 17 and 18 having a predetermined height and surrounding the bottom plates 15 and 16 and joined at their lower ends. The bottom plates 15, 16 and the side plates 17, 18 are made of cardboard, but may be single-sided cardboard. The single-sided cardboard is formed by joining a corrugated plate and a flat plate.
It is preferable to arrange the corrugated sheet outside the inner box so that the valleys and the ridges are oriented vertically.

The outer cylindrical body 13 is made of cardboard or one-sided cardboard, and has a fold 19 formed vertically at an intermediate portion and a cut (that is, a cut end) 2 at the other end.
0 and 21 are formed, and the cuts 20 and 21 are opened around the fold 19. In addition,
The radius of curvature of the outer cylinder 13 is the first and second middle boxes 11 and 12.
Is the same as the radius of the outer circle of
21 to 5 to 15 degree overlap (overlap)
have. The right half of the first middle box 11 and the left half of the second middle box 12 are adhered to the inside of the outer cylindrical body 13. The hatching of the oblique dotted line shown in FIG. 1 indicates a first joint 11a between the first middle box 11 and the outer cylinder 13 and a second joint 12a between the second middle box 12 and the outer cylinder 13. The first and second middle boxes 11 and 12 are attached to cuts 20 and 21 respectively.
2 is not adhered by about 10 to 20 degrees, and as shown in FIG. 2, the overlapped portion 22 of the cuts 20 and 21 can be partially fitted into the unadhered part.

The first and second middle boxes 11 and 12 have a predetermined gap S (for example, 1 / H of the height of the first and second middle boxes 11 and 12).
2-1), and the gap S described above is also provided between the top of the first inner box 11 and the top of the outer cylinder 13. Thereby, objects larger than the height of the first and second middle boxes 11 and 12 can be stored. The lid 14 includes a circular ceiling plate 23 made of cardboard and a low side plate 24 made of single-sided corrugated cardboard, and is joined to the ceiling plate 23 at its upper end. As shown in FIG. 2, the inner diameter of the lid 14 is slightly larger than the outer diameter of the outer cylindrical body 13 in a state where the cuts 21 and 22 are overlapped, closed and circular when viewed from above (0.5 to 2).
mm).

Therefore, when the paper box 10 is opened,
The cuts 20 and 21 to be polymerized are opened around the fold 19, and in this case, the outer cylinder 1 in the right half in FIG.
3, a first inner box 11 is attached, and a left half outer cylindrical body 13 is attached.
The left half of the second middle box is attached and opened. Here, when an object is put in the first and second inner boxes 11 and 12 and closed,
As shown in FIG. 2, by covering the lid 14,
The paper box 10 is fixed in a closed state.

In the above embodiment, the case where the inner box is circular in plan view has been described. However, the present invention is applied to, for example, a square box, and further includes at least two inner boxes.
The present invention is also applicable to a case where a plurality of middle boxes are provided. Further, in order to further strengthen the closed state of the paper box 10, a bottom lid having the same shape as the lid 14 may be provided in some cases.

[0012]

The paper boxes according to the first to fourth aspects are arranged in two upper and lower stages having a bottom plate and a side plate. The first and second inner boxes have first and second joints on the inside where the right and left half side plates of the first and second inner boxes are joined, respectively, and the first and second joints are provided.
A fold is formed in a longitudinal direction at a circumferentially intermediate position of the joining portion, and a cut is formed on a circumferentially outer side of the first and second joining portions. With closed
The first and second middle boxes can be easily opened and closed because of the lid that covers the upper part. Further, since the first and second middle boxes are attached to the outer cylinder, there is no risk of losing them. Further, the articles can be displayed in the first and second middle boxes by simultaneously storing and expanding the articles. In particular, the paper box according to the second aspect is easy to manufacture because the first and second middle boxes are circular in plan view. In the paper box according to the third aspect, when the outer cylinder body is closed with the first and second middle boxes inside, the outer cylinder has an overlapped portion at the cut portion, so that when the outer cylinder body is closed, the inner portion starts from the cut. I don't understand the situation, and the appearance is good. And in the paper box of Claim 4,
Since the side plates of the first and second middle boxes and the outer cylinder are made of single-sided cardboard or cardboard in which a corrugated plate and a flat plate are joined, a strong and relatively durable box is manufactured with a light weight. can do.
