Description

The present invention relates to a packing material for eaves for forming a box suitable for storing and transporting a plurality of eaves.

In order to transport or store the eaves, generally, a long box formed by assembling a packing material made of a sheet-like material such as corrugated paper is used. Are housed in a stacked state in which the eaves are fitted together.

In order to prevent dancing due to play of eaves in the box during transportation, it has been proposed to arrange spacers (see, for example, Patent Documents 1 and 2).

By this spacer, it is possible to prevent the eaves from dancing in the box during transportation, and it is possible to prevent the eaves from being deformed by the dance and from being damaged due to contact between the eaves.

However, during transportation, for example, an accident that drops the box from the end to the ground occurs, so if the weight of the eaves in the box acts on the corner of the end of the box that contacts the ground, the box The corners of the plate may be greatly deformed, and cracks and cracks may occur at the ends of the eaves housed inside.

In order to protect the eaves inside the box from such an accident, it has been proposed to attach protective members for reinforcement to both ends of the box (for example, see Patent Document 3).

Since the end of the box is reinforced by the attachment of the protective member, the corners of the box are prevented from being crushed, thereby preventing the eaves from being damaged due to the crushed corners of the box.

However, the protective member attached to the end of the box needs to be formed in advance from a separate material from the packing material constituting the box, and the protective member is separate from the packaging material assembly process. Need to assemble. Therefore, there has been a problem that the material cost for packing the eaves is increased and the labor for packing is increased.

SUMMARY OF THE INVENTION An object of the present invention is to provide an eaves packaging material that can suppress an increase in packing cost and packing labor and can transport eaves without damaging them.

The present invention is a packing material for eaves for forming an elongate box that accommodates eaves, and a main body in which both sides are connected to each other to form a cylindrical body open at both ends, and the main body A pair of side flaps continuously formed at both end edges of the main body and constituting an end wall of the cylindrical body, and at least one of the side flaps is outward from the cylindrical body at right angles to the longitudinal direction of the cylindrical body It has the overhang | projection part which can project to the side.

As the packing material according to the present invention, for example, corrugated paper or other foldable sheet-like material can be used. When the overhanging portion formed on the side flap constituting the end wall of the cylindrical body and projecting outward from the cylindrical body is subjected to an impact, it acts to alleviate the impact by its deformation. Therefore, since the eaves housed inside the box is protected from the impact, it is possible to prevent the eaves housed inside from being cracked or damaged by the impact.

The projecting portion protruding outward from the cylindrical body can be folded back along the cylindrical body to reinforce the end of the box. By folding the overhanging portion, the corners of the end of the box can be more effectively reinforced without using a separate protective member as in the past, and the corners can be more easily crushed by dropping the box. It can be surely prevented.

A recess having a shape capable of receiving the overhanging portion corresponding to the overhanging portion can be formed in the end edge of the main body or the base portion of the side flap continuous to the end edge.

A plurality of boxes are aligned vertically, for example, so that the recess of one box made of a packing material faces the protruding portion of the side flap of another box made of another packing material. In the case of stacking, the recess and the overhang corresponding to each other in the vertical direction can be fitted to each other. Therefore, in this case, the two boxes can be placed in close contact with each other without causing a gap between the plurality of boxes. In addition, since the recess and the overhanging portion are engaged with each other to form a positioning action between the boxes, the boxes are aligned without causing any deviation between the boxes. It becomes possible to stack.

According to the present invention, the shock acting on the end of the box is reduced or the end is not attached to the end of the box formed by the packing material, without attaching a protective member which is a separate member from the box. Since it can reinforce, the eaves can be reliably protected without incurring a conventional increase in packing cost or assembly time.

  The features of the present invention will be described along the illustrated embodiments.

As shown in FIG. 1, the packaging material 10 according to the present invention is made of a foldable sheet-like member such as cardboard. The packing material 10 has a rectangular main body 11 and a plurality of side flaps 12 (12a, 12b to 12e) formed continuously on the main body.

In the longitudinal direction of the main body 11, crease lines 13 parallel to each other are formed. By these crease lines 13, the main body 11 has a top wall portion 11 a, a side wall portion 11 b, a bottom wall portion 11 c, and a side wall portion 1.
1d and the overlapping part 11e are sequentially partitioned. In the illustrated example, the top wall 11a and the bottom wall 1
1c and the overlapping portion 11e are given a dimension L1 in the lateral direction perpendicular to the longitudinal direction of the main body 11,
The side wall portions 11b and 11d are similarly given the dimension L2.

These wall portions 11a to 11e can be overlapped with each other such that the top wall portion 11a is positioned outside the overlapping portion 11e by mountain folds or valley folds along the crease line 13. By joining the top wall portion 11a and the overlapping portion 11e on both sides of the main body 11, as shown in FIGS. 2 and 3, a cylinder having a rectangular cross-sectional shape having a width dimension L1 and a height dimension L2 A body is comprised by each wall part 11a-11e.

Referring again to FIG. 1, each side flap 12 (12 a, 12 b to 12 e)
1 is formed continuously at both end edges. A pair of side flaps 12b to 12b formed on both side edges of the side wall portions 11b and 11d, the bottom wall portion 11c and the overlapping portion 11e excluding the top wall portion 11a
12 e is partitioned from the main body 11 by crease lines 14 and 14 formed at both ends of the main body 11.

The side flaps 12b and 12d formed on the side wall portions 11b and 11d are given a dimension L3 smaller than the height dimension L2 along the direction of the height dimension L2, and the bottom wall part 1
The side flaps 12c and 12e formed in 1c and the overlapping part 11e are given a dimension L4 smaller than the width direction dimension L1 along the direction of the width direction dimension L1. Further, these side flaps 12b to 12e are provided with an overhanging dimension L5 that is smaller than the width dimension L1 and the height dimension L2.

Therefore, each wall part 11a-11e comprises a cylinder, and these side flaps 12 are then used.
When b-12e is bent along the crease line 14, the side flaps 12b-12e do not protrude outward from the cylinder constituted by the walls 11a-11e, and the lateral cross-sectional shape of the cylinder Overlap each other.

On the other hand, the side flaps 12b to 12 which are bent first are formed at both end edges of the top wall portion 11a.
a pair of side flaps 12a and 12a which are bent so as to be located on the outermost side of e.
Is formed.

Each side flap 12a has a width dimension substantially equal to the width dimension L1 of the top wall part 11a, and extends in a direction away from each edge of the top wall part 11a. At the extending end of each side flap 12a, an overhanging portion 15 extending beyond a length equal to the height dimension L2 of the side wall portions 11b and 11d is formed. In the example shown in the drawing, a pair of overhang portions 15 are formed on both sides of each side flap 12a at intervals in the width direction of the side flap 12a.

Further, a pair of recesses 1 corresponding to the shape of the overhanging portion 15 is formed at the base portion of each side flap 12a.
6 is formed. Each recess 16 has a size and a shape sufficient to receive each overhang 15 formed on both sides of each side flap 12a, and is formed by a notch in the example shown in FIG.

As described above, in the state where the cylindrical body having the rectangular cross section having the width dimension L1 and the height dimension L2 is constituted by the wall portions 11a to 11e, as shown in FIG.
A plurality of eaves rods 17 having a length of 6 m are accommodated in a state of being fitted to each other. The weight of the entire eaves 17 accommodated is, for example, about 20 kg.

In the state where the eaves bowl 17 is accommodated, as described above, the both side wall portions 11b except the top wall portion 11a,
1d, the pair of side flaps 12b, 12c, 12d, and 12e formed at the both end edges of the bottom wall portion 11c and the overlapping portion 11e are bent, and then the side flaps 12
Each side flap 12a formed in the top wall part 11a is bend | folded so that b-12e may be covered. This side flap 12a is fixed to the cylinder using, for example, an adhesive tape,
By overlapping these side flaps 12a to 12e, an end wall of the cylindrical body constituted by the respective wall portions 11a to 11e is constituted, and thereby a box body in which the eaves 17 is accommodated is constituted. The side flaps 12a are, as necessary, the side flaps 12b, 12c directly below the side flaps 12a.
It can be fixed to 12d or 12e as appropriate using an adhesive tape or an adhesive.

Since each side flap 12a formed on the top wall portion 11a is formed with an overhanging portion 15 extending beyond a length equal to the height dimension L2 of the side wall portions 11b and 11d, the side flap 12a is attached to the side flap 12a. In the bent state, as shown in FIG.
Projects downward from As described above, the projecting dimension h has a packing weight of about 20 kg.
For example, it is formed to be 5 mm or more.

The packaging material 10 according to the present invention is used to transport the eaves 17. For this transportation, as shown in FIG. 3, the eaves 17 is housed and transported inside the box constituted by the packing material 10, but during transportation, for example, as shown in FIG. When an accident occurs in which one end of the box body falls on the ground 18, and the overhanging portion 15 that protrudes from the bottom wall portion 11 c of the box body strongly hits the ground 18 due to the fall, the overhanging portion 15 is deformed. Crush.

The overhanging portion 15 relaxes the energy of impact by the deformation. Due to the impact mitigating action of the overhanging portion 15, the corners of the box are prevented from being crushed and the eaves 17 housed inside the box body is protected from the impact.

As a result, it is accommodated in the box comprised by this packing material 10 from the impact at the time of dropping of the packing material 10, without attaching the edge protection member like the conventional to the box comprised by the packing material 10. It is possible to prevent the eaves bowl 17 from being cracked or damaged.

Moreover, as shown in FIG. 5, in the state which accommodated the eaves basket 17 in each box (10,10) comprised with the packing material 10, each can be accumulated and stored mutually. In this storage, the recess 16 of the lower box (10) and the overhanging portion 1 of the side flap 12a of the upper box (10).
A plurality of boxes (10, 10) are stacked in the vertical direction so that 5 faces each other. By this stacking, the recess 16 and the overhanging portion 15 corresponding to each other in the vertical direction can be fitted to each other.

Therefore, in this stacking, the bottom of the upper box (10) and the top of the lower box (10) are arranged in close contact with each other without any gaps between the plurality of boxes (10, 10). Can be made. Furthermore, the recess 16 and the overhanging portion 15 are fitted to each other, so that both box bodies (
10 and 10), the box bodies (10, 10) can be easily aligned and stacked in the vertical direction without causing a shift between the box bodies.

Instead of forming a pair of overhang portions 15 on both sides of each side flap 12a, a single overhang portion 15 can be formed at the center of each side flap 12a. However, in order to effectively protect the corners that are easily damaged when the box is dropped, it is desirable to form the pair of overhang portions 15 on both sides of the side flap 12a as described above.

Further, the overhanging portion 15 can be formed on both sides of the side flap instead of or at the tip of each side flap 12a. Moreover, it can replace with each side flap 12a, and can be suitably formed in the other side flaps 12b-12e, unless the bending of the side flap 12 (12a-12e) is prevented.

Further, as shown in FIG. 6, the tip of the overhanging portion 15 formed on the side flap 12a can be folded back toward the bottom wall portion 11c that constitutes the cylindrical body, and the folded portion can be turned into the bottom wall. The part 11c can be fixed using an adhesive or the like.

The overhanging portion 15 whose tip is folded back and fixed to the bottom wall portion 11c serves to reinforce the end of the box (10). Accordingly, as in the usage mode shown in FIG. 5, the corners of the end of the box (10) can be reinforced, preventing the corners from being crushed due to the fall of the box (10). Prevents damage to the housed eaves 17.

In the example shown in FIG. 5, the recess 16 has the overlapping portion 1 in order to receive the folded portion of the overhang portion 15.
It extends to the top of the box (10) so that the edge of 1e is partially exposed. Accordingly, as in the example shown in FIG. 4, a plurality of boxes (10) can be stacked in close contact with each other in the vertical direction, and the recess 16 and the overhanging portion 15 are used for positioning at that time. can do.

According to the present invention, as described above, without using a protective member that protects the end portion separately from the packaging material 10, therefore, without increasing the material cost required for the protective member and increasing the labor of packaging, The eaves rod 17 can be reliably protected from impacts such as when dropped, and a plurality of eaves rods 17 can be transported safely and efficiently.

Moreover, since a plurality of boxes (10) can be easily aligned and stacked without any vertical spacing, the storage operation can be speeded up, and the collapse of the cargo can be prevented and the storage space can be reduced. Effective for reduction.
