Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper box which can be compactly folded for disposal.

[0002]

2. Description of the Related Art Generally, when discarding a paper box used for gift wrapping or the like, the paper box is often disassembled and folded flat and tied in order to suppress rebound of the fold.

[0003] Incidentally, since it takes time to hang such a strap, it is conceivable to cut the edge of a blank forming a paper box to provide a lock piece, and suppress the rebound of the fold by the engagement.

[0004]

However, when the lock piece is provided at the end of the blank as described above, there is a problem that the area in the folded state increases.

Therefore, an object of the present invention is to provide a paper box that can be compactly folded and discarded.

[0006]

In order to solve the above-mentioned problems, the present invention relates to a box in which a pair of end plates and side plates are connected to the periphery of a substrate, and the end plates and the side plates are connected to form a peripheral wall. A continuous fold line is provided on the substrate and the side plate, and a lock piece is formed by cutting the ridge of the substrate and the end plate with the fold line as a symmetric axis.

When the lock piece is provided at such a position, it can be folded in two along the fold line, the end plate can be folded inward and locked, and can be discarded without being bulky.

[0008]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 1, the paper box is composed of a body 1 for storing a product and a lid 2 to cover the body.

The body 1 is made of a blank shown in FIG. 2. In this blank, an end plate 4, a top plate 5 and a superposed plate 6 are provided on two sides of one pair of the peripheral sides of the substrate 3, and the other pair is provided. A side plate 7, a top plate 8 and a superposed plate 9 are sequentially connected to two sides of the end plate 4 and the folded pieces 10 and 11 are continuously connected to both side edges of the end plate 4 and the superposed plate 9, respectively.

The substrate 3 and the side plates 7 and the top plate 8 on both sides thereof
In addition, a fold line 12 is provided continuously on the overlapping board 9, and the fold line 12 is used as an axis of symmetry, and the ridges of the substrate 3 and the end plate 4 are cut away from the centers thereof by a notch. A set of lock pieces 13 is provided.

Of the one set of lock pieces 13, one lock piece 13 becomes wider toward the tip, and the other lock piece 13 has a width generally equal to that of the tip of the one lock piece 13. It is narrower than the width.

A notch 14 for hooking a finger is provided at the center of the leading edge of the overlapping plate 6, and the edge is cut in a waveform so as not to cut a finger.

In order to assemble such a blank into the body 1, the end plate 4 and the side plate 7 are erected on the substrate 3, the bent piece 10 is sandwiched between the side plate 7 and the overlapping plate 9, and the bent piece 11 is It is sandwiched between the end plate 4 and the overlap plate 6.

On the other hand, the lid 2 is made of a blank as shown in FIG. 22
Are provided continuously, and bent pieces 23 are provided on both side edges of the side plate 22.
Are connected.

A fold line 24 is continuously formed on the substrate 20 and the side plates 22 on both sides thereof. The fold line 24 is used as a symmetry axis, and the ridges of the substrate 20 and the end plate 21 are arranged from the center thereof. At a displaced position, a set of lock pieces 25 by cutting is provided.

Of the one set of lock pieces 25, one lock piece 25 becomes wider toward the tip, and the width of the other lock piece 25 is generally equal to the width of the tip of the one lock piece 25. It is narrower than the width.

The end plate 21 is provided with a 45 ° fold line 26 starting from the corner of the substrate 20.

To assemble such a blank on the lid 2, the end plate 21 and the side plate 22 are erected on the substrate 20,
The bent piece 23 is attached to the end plate 21.

When the merchandise 1 is stored in the body 1 assembled as described above and covered with the lid 2, the merchandise can be packed like a normal paper box.

Further, even if the delivery strap is hung in this state, since the lock pieces 13 and 25 are displaced from the center in the width direction, there is no possibility that a gap between the cuts is broken and a gap is formed.

On the other hand, when the paper box is discarded, in order to fold the body 1, as shown in FIG. 4, a finger is put on the notch 14 to flip up the overlapping plate 6, and as shown in FIG. Fold it outward and bend the end plate 4 inward.

Then, as shown in FIG. 6, the flat body 1 is folded in two along the fold line 12, and the lock piece 13 having the widened end is bent in the direction of the other lock piece 13, and the end plate 4 To be engaged. Thereby, the body 1 is locked in the folded state.

In order to fold the lid 2, as shown in FIG. 7, the end plate 21 is bent inward along the fold line 26, and the side plate 2 is turned inward to flatten it.

Then, the flat lid 2 is folded in two along the fold line 24 as shown in FIG. 8, and the lock piece 25 having a widened end is bent in the direction of the other lock piece 25 to form an end plate. 21. Thereby, the lid 2 is locked in the folded state.

As described above, in the above paper box, the end plates 4, 21
Can be folded inward and locked by the lock pieces 13 and 25, so that the area in the folded state can be reduced.

At this time, since each of the lock pieces 13 and 25 is overlapped, the lock pieces 13 and 25 can be firmly locked in the folded state.

The body 1 and the lid 2 of the paper box can be used alone as a box for storing objects.

[0029]

As described above, the paper box according to the present invention is
With the fold line extending across the board and both side plates as the axis of symmetry, the locking piece by cutting was provided at the ridge of the board and the end plate, so it was folded in half along the fold line, the end plate was folded inward, and the double The lock piece can be firmly locked by the lost lock piece and can be discarded without being bulky.
