DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cushion cushion, and more particularly to a cushion cushion assembled by bending a cardboard.

[0002]

2. Description of the Related Art When various kinds of articles are provided for distribution or stored, the articles are stored in a packaging box made of cardboard or the like. I try to plan. For articles that are easily damaged by external impacts such as precision equipment, etc., a buffer is provided between the above-mentioned article and the packaging box, and the external impact is absorbed by such a buffer. , To protect the articles from impact.

[0003]

A cushioning cushion which has been widely used in the past is a foamed styrene resin molded into a predetermined shape. Such a styrofoam cushion has a problem that a mold is required for molding and another mold must be prepared if the shape is different. Further, when such a cushion made of styrofoam resin is discarded and incinerated, black smoke is generated and causes air pollution, or the incinerator is damaged by high-temperature heat.

[0004] In some cases, a discrete buffer formed by molding a styrene foam resin into beads or strings is filled in the gap between the article and the packaging box, thereby protecting the article from impact. In such a case, it is possible to extrude from an extruder and form into a predetermined shape without requiring a special mold for molding.

[0005] However, even with such a bead-like or string-like cushion made of styrofoam resin, problems of pollution and furnace damage at the time of disposal are not solved.

The present invention has been made in view of such problems, and does not require a special mold for molding, generates pollution during disposal, or generates heat due to high temperature heat. It is an object of the present invention to provide a cushion cushion that does not damage an incinerator.

[0007]

SUMMARY OF THE INVENTION One aspect of the present invention is an acute angle made of corrugated cardboard, which is alternately bent in opposite directions at a plurality of bending lines intersecting a step, and bent in a V-shape. And a portion in the vicinity of the bending line is adhered to the cushion cushion.

Here, the bending line may be perpendicular to the step. In addition, an acute portion bent in a V-shape and the vicinity of the bending line may be bonded with glue. A contact plate may be provided at one end or both ends in the expansion and contraction direction.

According to another aspect of the present invention, there is provided an acute-angle portion which is made of corrugated cardboard, is alternately bent in a reverse direction at a plurality of bending lines intersecting a step, and is bent in a V-shape. The present invention relates to a cushion cushion including a unit formed by bonding a portion near a bending line and combining a plurality of units.

[0010] Here, two sets of units may be formed by continuous cardboard, and the two sets of units may be arranged in parallel with each other. A plurality of units may be juxtaposed in parallel with each other, and abutment plates may be arranged at both ends of the plurality of units in the expansion and contraction direction. Further, the plurality of units may be housed in the rectangular tube, and the side plate in the expansion and contraction direction of the rectangular tube may have a bending line, and the side plate may be folded inward by the bending line.
Further, the first unit and the second unit may be attached to the contact plate bent at a right angle so as to be orthogonal to each other.

[0011]

According to the one aspect of the present invention, since an acute portion bent in a V-shape and the vicinity of the bending line is adhered, the elastic corrugated cardboard is used to restore elasticity. A force is generated, and a buffering effect is exhibited by such an elastic restoring force. Therefore, by interposing such a cushion cushion between the article and the packaging box, it becomes possible to protect the articles in the packaging box from external impact.

According to another aspect of the present invention, a plurality of units are formed by bonding an acute angle portion bent in a V-shape and in the vicinity of a bending line. Here, since each unit exerts a buffering effect due to the elastic restoring force, a cushion cushion formed by combining a plurality of such units exhibits a buffering effect. Therefore, by interposing such a cushion cushion between the packaging box and the article, the article can be protected from external impact.

[0013]

1 to 3 show a cushioning cushion according to a first embodiment of the present invention. Such a cushion cushion can be assembled from the cardboard 10 shown in FIG. Twelve bending lines 11 are formed in the corrugated cardboard 10 so as to be perpendicular to the step and parallel to each other and at a predetermined interval. Note that portions outside the bending lines 11 at both ends constitute the auxiliary pieces 13.

The corrugated cardboard 10 is bent alternately in the opposite direction at the bending line 11 as shown in FIGS. Moreover, bending line 1
As shown in FIG. 3, the V-shaped acute-angled portion bent by 1 and the vicinity of the bending line 11 are adhered by glue 15 as shown in FIG.

When glue 15 is applied to a V-shaped acute angle portion which is a portion to be bent by the bending line 11,
The generation of the elastic restoring force is mechanically equivalent to the case where the spacer member is interposed at the portion where the bonding has been performed with the glue 15, whereby the elastic restoring force is generated. In other words, it has been confirmed that when glue is applied to the acute-angled portion bent by the bending line 11, a much larger elastic restoring force is generated when gluing is performed than when gluing is not performed. In addition, the auxiliary pieces 13 on the tip side of the bending lines 11 at both ends of the corrugated cardboard 10 can be bent inward as shown in FIG.

A cushion cushion as shown in FIG. 2 is used for protecting articles stored in a packaging box. That is, when an article which is easily damaged by an impact is stored in the packaging box, the cushion cushion is arranged in a gap between the article and the packaging box. Then, it becomes possible to absorb the external impact by the elastic deformation of the cushion cushion, and it becomes difficult for the impact to be transmitted to the article, and the article can be protected from the external impact. Therefore, the cushioning cushion of the present embodiment can be used in place of the cushioning cushion made of a molded article of styrene foam resin.

Such a cushion cushion is made of cardboard 1
0, which is formed by folding a corrugated cardboard 10 using a punching die without using a molding die.
1 only, which results in a very inexpensive cushioning cushion. Moreover, such a cushion cushion is made of cardboard 10 and can be recycled because its raw material is pulp.
Also, when performing incineration disposal treatment, no harmful gas is generated, and the furnace is not damaged by high-temperature heat. Therefore, it does not cause waste pollution.

Next, a second embodiment will be described with reference to FIGS. In this embodiment, a cushion cushion is assembled by a continuous elongated corrugated cardboard. The elongated corrugated cardboard 10 is assembled in a substantially quadrangular cylindrical shape, and bent lines 11 are formed on both sides in the expansion and contraction direction of the quadrangular tube, and the bent lines 11 are bent alternately zigzag at such bent lines 11. In addition, an acute angle portion bent in a V-shape and the vicinity of the bending line 11 is adhered by the glue 15.

Therefore, such a cushion cushion is provided in FIG.
A pair of left and right buffer units are arranged side by side as shown in FIG.
Will result in a connected structure. Such a cushion cushion functions to cushion a vertical shock in FIG. In addition, since it is composed of an assembly of a pair of right and left units, the structure has excellent shock absorbing performance.

Next, a third embodiment will be described with reference to FIGS. In this embodiment, three units are arranged between a pair of upper and lower rectangular contact plates 17. Each unit is the same as that of the first embodiment, and is formed by forming a bending line 11 on a corrugated cardboard 10 and sequentially bending the bending line 11 in the reverse direction at the bending line 11. An area which is bent by the bending line 11 and is a sharp-angled portion bent in a V-shape, and the vicinity of the bending line 11 is adhered by the glue 15.

Therefore, in such a cushion cushion, the cushioning effect can be obtained by the elastic restoring force developed by the three units arranged between the upper and lower contact plates 17, respectively. A similar effect can be achieved.

FIG. 8 and FIG. 9 show still another embodiment. In this embodiment, a buffering unit is arranged in a rectangular cylindrical frame. That is, three units are arranged in a square cylindrical frame body including a pair of contact plates 17 and side plates 20 between these contact plates 17. Here, the units are arranged between the contact plates 17 on both sides, and each unit 17 forms a bending line 11 on the corrugated cardboard 10 and is bent at the bending line 11 alternately in the opposite direction. It has a shape. Moreover, glue 15 is adhered to each of the bent lines 11 and the acute-angled portions bent in a V-shape, thereby generating a high elastic restoring force.

Therefore, according to such a structure, the units inside and outside expand and contract to change the distance between the contact plates 17 on both sides. At this time, the amount of the side plate 20 folded inward by the folding line 21 formed at the intermediate position changes, and the deformation of the unit is absorbed.

Next, a fourth embodiment will be described with reference to FIGS.
1 will be described. This cushioning cushion is provided with a right-angled contact plate 25 on an outer portion, and four units are attached to two plate-like portions of the contact plate 25 orthogonal to each other. One end of each unit in the expansion and contraction direction is attached to a right-angle contact plate 25, and the opposite end is bonded to the contact plate 17. The side end of the abutment plate 17 and the side end of the abutment plate 25 at a right angle may be connected to each other by a connection plate 27, or the connection plate 27 may be omitted and the abutment at a right angle to the abutment plate 17 The contact plate 25 may be formed of different members.

Such a structure simultaneously absorbs shocks in two directions perpendicular to each other. Thus, such a cushion may be arranged, for example, at the corner of a packaging box. Such a cushion cushion also has the same operation and effect as the above embodiment.

[0026]

According to one aspect of the present invention, an acute angle portion formed of a corrugated cardboard, which is alternately bent in a reverse direction at a plurality of bending lines intersecting the step, and which is bent in a V-shape. In this case, the vicinity of the bending line is bonded.

Therefore, the corrugated cardboard is alternately bent in the opposite direction, and a sharp angled portion bent in a V-shape is bonded to the vicinity of the bending line, thereby providing a buffer having a high elastic restoring force. A cushion will be obtained. Such a cushion cushion allows the article to be protected from impact. Further, since such a cushion cushion is made by assembling cardboard, it is not only recyclable but also does not cause pollution when incinerated and disposed of.

Another aspect of the present invention is an acute-angled portion made of corrugated cardboard, which is alternately bent in opposite directions at a plurality of bending lines intersecting the step, and is bent in a V-shape. A unit formed by bonding the vicinity of a bending line is provided, and a plurality of units are combined.

Therefore, according to such a configuration, a cushion cushion can be obtained by combining a plurality of units formed by bending a cardboard. In such a cushion cushion, a cushioning effect is generated by the elastic restoring force expressed by each unit, and the shock absorbing performance can be arbitrarily adjusted.
