Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cardboard box in which a box is formed by bending a plate-shaped cardboard so that an object can be stored in the box. The present invention relates to a cardboard box with a hanging string.

[0002]

2. Description of the Related Art In a conventional cardboard box with a hanging string, a string passed through a hole provided in a side wall is formed into a loop to form a hanging string.

[0003] When a heavy object is stored in a hoist hung with a strap or carried, the weight is received by the hole, so that stress concentration occurs, and the side wall itself tends to tear and break. For this reason, a reinforcing plate has been integrated around the hole by bonding or the like to supplement the strength.

[0004] Hereinafter, a conventional cardboard box with a hanging string will be described with reference to FIG.

In the drawing, reference numeral 1 denotes a side wall, which forms a square with four walls. Two holes 6 and 7 are provided in the side wall, and a rectangular reinforcing plate 4 is adhered to the inside of the side wall. The reinforcing plate itself is also provided with two holes at the positions of the holes 6 and 7, and the strings passing through these holes are tied together so as to form a loop outside the side wall to form the hanging string 5. ing. The hanging string 5 is provided in a pair with a similar structure on a pair of opposing side walls.

[0006]

The above-described cardboard box with a hanging string requires a high-strength reinforcing plate in order to prevent the side wall itself from being damaged due to the tearing of the hole, and the reinforcing plate is bonded. It is inevitable that the cost will increase due to the necessity of manual work for performing the operation.

[0007] The present invention is intended to solve such a problem of the conventional structure, and an object thereof is to realize an inexpensive cardboard box with a strap.

[0008]

In order to achieve the above object, a cardboard box with a hanging string according to the present invention has a hole formed in a bottom wall of a cardboard box, and a string passed through the hole is attached to the outside of the side wall (outside of the box). ) Is formed in a loop shape to form a hanging string.

Further, the bottom wall is formed by a pair of flaps extending integrally from the opposed bottom wall, and the holes are provided in each of the pair of flaps, and the string is provided between the pair of holes by the bottom wall. It is more effective to use a hook string that passes through the inside of the box (the inside of the box) and forms a loop shape outside the side wall.

Further, the side wall having the hole is different from the side wall.
A pair of opposing walls is provided with a ruled line extending in the direction of the bottom wall and having reduced bending rigidity, and the holes are provided so that the pair of holes overlap at the same position when the entire side wall is crushed along the ruled line. Is more preferred.

[0011]

[Function] The cardboard box with the hanging string configured as described above is a state in which heavy objects are packed in the box.
When hanging or carrying with a hoist using a hanging string, the hanging string can support the weight in the form of holding the entire box, reinforcing the strength of the entire box. For this reason, it is possible to omit the expensive reinforcing plate for reducing the stress concentration generated in the cord hole and the trouble of bonding the reinforcing plate as in the related art, and to further reduce the material of the box body. I can do it.

In the case where the bottom wall is formed by the pair of flaps, the string passes through the inside of the bottom wall between the holes provided in both flaps, and the loop-shaped hand strap is formed outside the side wall, The strap is more stably held by the bottom wall and the side wall when lifting the garment, which is more effective.

Further, the entire side wall composed of the four walls is pushed along a ruled line formed at the center of the pair of opposing side walls, which is different from the pair of side walls connected to the pair of flaps provided with the string holes. If the string is passed through the overlapped holes in the crushed state, the hanging string can be easily formed, which is more preferable.

[0014]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

In FIG. 1 (a bottom perspective view of a cardboard box with a hanging string), reference numeral 1 denotes a side wall, which has a rectangular shape composed of four walls formed by bending a plate-like cardboard. 2
Indicates a bottom wall, and 3 indicates a lid. The bottom wall 2 is formed by bending a pair of flaps 21 and 22 extending from the side wall 1, and a joint portion between the pair of flaps is generally sealed with a gum tape or the like. Similarly, the lid 3 can be sealed.

The flap 21 of the bottom wall 2 has two holes 21.
A and 21B have two holes 22A and 22 in the flap 22.
B is provided, and the string is passed through 21A and
After drawing one loop outside the side wall from 2A, it is again passed through the hole 22B and out of the bottom wall through the inside of the bottom wall to draw the other loop outside the side wall. Both ends of the string are tied. These loops are used as hanging strings 5 when suspended by a hoist in a state where a heavy object is stored in a box or when the box is carried.

As the hanging string 5, a flat string called a polypropylene-knitted round string, flat string or suf is generally used, but a flexible and cheaper one depending on the weight to be suspended may be selected. It is important. Similarly, the end of the string is appropriately selected and used, such as tying, bonding, welding, fastening of metal fittings, or the like.

Next, a method of manufacturing a cardboard box by bending a flat cardboard will be described with reference to FIG. First, ruled lines 8E and 8F (bent lines) for reducing bending rigidity are drawn on a flat cardboard.
Ruled lines are generally two rolls (diameter 30CM, width 2CM)
(A rotating disk) is formed by passing a plate-shaped cardboard. One of the two rolls has one projection (large-diameter portion) at the center in the width direction, and the other roll has two projections (large-diameter portion) formed in the width direction. To form a single line on the front surface and two lines on the rear surface, and a ruled line with low bending rigidity is drawn. The upper part of the ruled line 8F in the figure is the flap portion of the lid 3, the part between the ruled lines 8F and 8E is the flap of the bottom wall 2 in the figure below the ruled line 8E. In the case of a box without a lid, the ruled line 8F is naturally unnecessary.

Next, the ruled lines 8A, 8B, 8C,
8D is subtracted. The rectangular side wall 2 can be formed by sequentially bending along the ruled line, and bonding or stitching with a margin 15. In the case of a large box, a flat cardboard can be divided by the ruled line B, and a margin can be provided at this portion to be integrated.

Further, holes 21A and 21B are formed in the flap 21 forming the bottom wall, and holes 22A and 22B are formed in the flap 22.
B and ruled lines 81 and 82 are formed. In addition, a slit is provided between each flap to avoid mutual interference when the bottom wall 2 and the lid 3 are formed by bending. Each of these is formed by passing a plate-shaped cardboard between two rolls similarly to the above-mentioned ruled line. That is, a protrusion is provided at a predetermined position on the circumference of one roll, and a recess is provided on a corresponding circumference of the other roll, and a predetermined shape can be easily cut out at a predetermined position on the cardboard by rotating the roll. .

The positions and intervals of the holes 21A, 21B, 22A and 22B are preferably changed according to the individual weights so that the weights to be packed in the cardboard box can be suspended safely and in a well-balanced manner. A variety of holes can be easily formed at predetermined positions only by moving the rollers in the axial direction and the circumferential direction.

Further, the bottom wall 2 is formed by flaps 21 and 22 on the long side having holes, but when a gap between the flaps on the short side is laid and filled with another cardboard pad, the bottom wall is formed as a double bottom. Sufficient strength can be provided.

Next, a method of attaching a hanging string will be described with reference to FIG. 1 is a side wall, 2 is a bottom wall, and 3 is a lid. Holes 21A, 21B, 22 of flaps 21, 22 forming bottom wall 2
A and 22B are rectangular side walls 1 formed by ruled lines 81 and 82 provided on a pair of opposing walls different from the side wall connected to the flap.
When the whole is crushed, it overlaps at the same position. In this state, a string is passed through and the ends are tied to form a loop, and this loop has a loop on the outside of the opposing side wall.
Individual straps are formed at once. This crushed cardboard box with a hook string is provided to the user in a stacked state.

In addition, the hanging straps are holes 21A, 21B, 22
A, It is a shape that can move freely in 22B, when the box is lifted, the length of the left and right hand straps can be adjusted uniformly, but if necessary, friction occurs between the strap and the hole, Narrowing the string as a variant that partially narrowed the hole,
A slit is provided around the hole to allow the string to bite into the slit, or the string is temporarily fixed to the side wall or the like with cellophane tape (registered trademark) to preliminarily set the left and right lengths of the hook strap. You can keep it.

[0025]

Since the present invention is configured as described above, it has the following effects.

A hole is provided in the bottom wall of the cardboard box, and the string passing through the hole is formed into a loop on the outside of the side wall so that the string holds the box when the box is hung. Eliminates the need for expensive reinforcing plates and reinforcing plate bonding to prevent breakage of the box due to tearing,
An inexpensive box can be provided.

The above-mentioned hole is provided in each of a pair of flaps forming the bottom wall. After the string passes through the inside of the bottom wall through the hole, a loop-shaped hanging string is formed outside the side wall.
When hanging the box, it can be lifted more balanced and smooth.

If the entire rectangular side wall is crushed along a ruled line provided on a pair of side walls different from the side wall connected to the pair of flaps, and the string is passed in a state where the pair of holes overlap each other, it is easier. A hanging string can be formed, and a box with low cost can be provided because labor can be saved.
