In this storage box, a cylindrical body 50 is formed by connecting four body plates 51 in series, and flaps 52, 52 are provided on a pair of body plates 51, 51 facing each other, and flaps 52, 52 are provided on the other pair of body plates 51, 51. 53 and 53 are connected in series, and the flaps 52 and 53 are sequentially bent inward with respect to each body plate 51 and bonded together, thereby closing both end surfaces of the cylindrical body 50.

[0003] A cutting band 54 made of a zipper is formed on the outer periphery of one end of the cylindrical body 50. The surface surrounded by the separating band 54 is inclined with respect to the end surface of the cylindrical body 50, and one end is formed. The end face has been reached.

[0004] The other end of the cylinder 50 is provided with
As shown in FIG. 13, the insertion pieces 55 are cut into the center portions of the front ends of the outer flaps 53, 53, and the cut portions 56 into which the insertion pieces 55 can be inserted are formed at the front edges of the inner flaps 52, 52. Each is formed.

[0005] In the above-mentioned storage box, the separating band 54 is pulled,
When each body plate 51 is cut, as shown in FIG.
One end of the zero can be removed. When storing the opened storage box sideways, the protruded body plate 51
Is positioned below, the warp of the tissue paper due to its own weight is prevented.

On the other hand, the other end of the cylindrical body 50 is
Even after the adhesive portions 2 and 53 are peeled off and once opened, the insertion piece 55 is bent inward with respect to the flap 53 so that the notch 5
6 can be resealed.

Therefore, in this storage box, at the time of opening, it is only necessary to select which end of the cylindrical body 50 to open according to the storage method.

[0008]

However, in the above-mentioned storage box, at one end of the cylinder 50, the separation band 54
0, and the opposite body plates 51, 51
Are cut off in an oblique direction, so that when a large external force is applied during transportation, there is a problem that the separation band 54 is easily torn.

Further, at the other end of the cylindrical body 50, a plurality of cuts are provided at the tip edges of the flaps 52 and 53, respectively. 52 and 53 were torn, making resealing difficult.

Accordingly, an object of the present invention is to provide a thin paper storage box which is excellent in strength and can be securely resealed without inadvertent tearing of the separation band during transportation and storage.

[0011]

In order to solve the above-mentioned problems, according to the present invention, a cylindrical body is formed by continuously connecting four body plates, and a flap connected to a pair of opposed body plates is provided. On the inside, the flaps connected to the other pair of body plates are overlapped with the outside facing outward, the inner and outer flaps are adhered to each other to close both end surfaces of the cylinder, and cut at one end of the cylinder. In a corrugated cardboard tissue storage box provided with a resealing means at the other end, the cutting means is formed on a three-sided body plate, and a separating band parallel to the edge thereof and a remaining body plate are provided. A configuration consisting of a flap and a separation line provided at a continuous portion was adopted.

This storage box has excellent strength because the separation band is parallel to the edge of the body plate and does not reach the end of the cylindrical body.

Now, in this storage box, in order to open one end of the tubular body, a cutting band is pulled to cut the three body plates,
The ridge line between the other body plate and the body plate adjacent on both sides thereof is torn, the separation line is cut, and one end of the three body plates is removed together with the four flaps. This opening operation can be performed even in a state where the cylinder is turned sideways with the body plate having the separation line facing down.

When the package is opened in this manner, the lower body plate is in a protruding state, so that the thin paper package can be prevented from warping due to its own weight.

[0015] On the other hand, the resealing means includes an insertion piece provided at both end corners of one of the outer pair of flaps via oblique fold lines, and a pair of inner flaps. And the insertion piece can be inserted into the insertion hole, since there is no cut in the leading edge of the flap, the first in the other end of the cylindrical body When peeling off the sticking portions of the flaps at the time of opening, the flaps are not torn and the re-sealing can be surely performed by inserting the insertion piece into the insertion hole.

[0016]

FIG. 1 shows an embodiment of a development board of a storage box according to the present invention. This development board is made of corrugated cardboard, and body plates 1 to 4 are successively provided with their side edges abutting each other, and the step direction thereof is in a direction intersecting the connecting direction of the body plates 1 to 4. A glue allowance 5 is provided on the open side edge of the body plate 1, flaps 6 to 9 are provided on both end edges of the body plates 1 and 3, and flaps 10 to 13 are provided on both end edges of the body plates 2 and 4.
Are connected to each other.

At one end of the body plates 1, 2, and 4, a zipper-type separation band 14 is formed in parallel with the edge. As shown in FIG. 9, one of the liners 16, 16 adhered to both sides of the core paper 15,
As shown in FIG. 8, two cut lines 17 may be formed on each body plate 1 to 4 to form a liner cut type. In this case, perforations 18 may be formed on both sides of the cut lines 17 of the body plates 1, 2, and 4 in order to smoothly cut the separation band 14.

A separation line 19 is formed at a continuous portion between the body plate 3 and the flap 8, and a separation band 14 is formed on both side edges of the body plate 3.
Is provided with a notch 20 at the end portion. This cut 20
Is for preventing breakage to the body plate 3 when the cutting band 14 is cut.

Further, at both ends of the flap 7, insertion pieces 23 are provided via oblique fold lines 22, and flaps 11 and 13 have insertion holes 24 into which the insertion pieces 23 can be inserted. Are formed.

At the other end of the body plate 1, notches 7a, 7a extending from both edges of the flap 7 are formed, and their base ends are connected by a fold line 7b. These are intended to enlarge the opening at the time of forming the box and to facilitate taking out the thin paper.

In order to assemble the developed substrate into a storage box as shown in FIG. 2, first, the body plates 1 to 4 are bent inward, and a glue allowance 5 is attached to the body plate 4 to form a cylinder 25. . Then, the flaps 10 to 13 are bent inward with respect to the body plates 2 and 4, then the flaps 6 to 9 are bent inward with respect to the body plates 1 and 3, and the flaps 6 and 8 are fitted to the flaps 10 and 12, respectively. By attaching the flaps 7 and 9 to 11 and 13 respectively, both end surfaces of the cylindrical body 25 are closed.

In the storage box assembled in this manner, the separation band 14 is parallel to the edges of the body plates 1, 2, and 4,
Since the separation band 14 does not reach the end of the cylindrical body 25, the strength is excellent.

Now, in this storage box, in order to open one end of the cylindrical body 25, as shown in FIG. 3, the separating band 14 is pulled to cut the body plates 1, 2, and 4; As shown in FIG. 4, the ridge line between the body plate 3 and the body plates 2 and 4 adjacent to both sides thereof is torn from the cut portion toward the end face of the cylindrical body 25. Then, the separating line 19 is cut, and one ends of the body plates 1 to 4 are removed together with the flaps 6, 8, 10, and 12. This opening operation can be performed not only in a state where the cylinder 25 is erected, but also in a state where the cylinder 25 is laid down so that the body plate 3 is on the lower side.

When the box 25 is opened in this way, as shown in FIG. 5, the body plate 3 is in a protruding state.
The warp due to the weight of the thin paper package P can be prevented.

On the other hand, at the other end of the cylindrical body 25, there is no cut at the leading edge of the flaps 7, 9, 11, 13 so that when the flaps 7, 9 are peeled off from the flaps 11, 13 at the time of the first opening, they are not cut. Does not tear. Therefore, even after once opened, as shown in FIG.
1, 13 and 7 are sequentially bent inward, and
