Abstract

PURPOSE:To provide cushioning material having excellent cushioning function and capable of being reclaimed by alternately sticking respective many corrugated strip sheets and strip sheets, and bending these sheets so as to respectively have elastic action. CONSTITUTION:For manufacturing the cushioning material 1, at first many pieces of corrugated sheet 10 which is constituted by sticking a sheet of liner 9 to an internal core 8 forming corrugated step, are laminated and stuck so as to form a block body 11. Next the block body 11 is cut off perpendicular to the ridge line of the internal core 8 by a decided width so as to form many meshy structures 4 composed of corrugated strip sheets 2 and strip sheets 3. Next, by setting the cutting section 12 of the meshy structure 4 as a pressure receiving face 7. And compressing the pressure receiving face 7 at decided pressure, the corrugated strip sheets 2 and the strip sheets 3 are bent so as to have elastic action and complete the cushioning material 1. Hereby the cushioning material 1 having excellent cushioning function and capable of being reclaimed is provided.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a regenerable cushioning material and a method for manufacturing the same.

[0002]

2. Description of the Related Art Conventionally, when a product is housed in a packaging box, a cushioning material made of Styrofoam is interposed between the packaging box and the product. Had to be discarded.

In recent years, however, various problems such as a burden on an incinerator and securing land at a landfill due to a rapid increase in waste have arisen. For this reason, recyclable articles have been produced for the purpose of reducing waste and saving resources. It has been reviewed, and there has been a demand for a substitute that can be recycled even in the cushioning material made of expanded polystyrene.

[0004]

DISCLOSURE OF THE INVENTION The present invention is to provide a cushioning material which is not inferior in its cushioning function to a cushioning material made of Styrofoam and which is reproducible, and a method for producing the same. .

[0005]

SUMMARY OF THE INVENTION The present invention is based on the above-mentioned prior art, and in view of the problem that it cannot be regenerated by a cushioning material made of expanded polystyrene, corrugated strip sheets and strip sheets made of kraft paper, corrugated cardboard sheet and the like are alternately bonded. Or, a plurality of corrugated strip sheets are adhered to each other to form a stitch structure, and the pressure receiving surface of the stitch structure is compressed to bend and form each of the sheets so as to have an elastic action. By providing a shock-absorbing material having a shock-absorbing function, the shock-absorbing material is reproducible and is not inferior in the shock-absorbing function to the one made of Styrofoam, and the above-mentioned drawbacks are not solved. .

[0006]

In the present invention, since the wavy strip sheet and the strip sheet in the stitch structure are kept in a bent state so as to have an elastic action, the cushioning material has a cushioning function.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings. 1 is a cushioning material according to the present invention. It is composed of a corrugated strip sheet 2 having a step and a strip sheet 3 having the same width and the same length as the corrugated strip sheet 2.

Reference numeral 4 is a stitch structure in which a plurality of corrugated strip sheets 2 and strip sheets 3 are alternately arranged and the strip sheet 3 is adhered to the ridge line 6 of the mountain portion 5 of the corrugated strip sheet 2.
The stitch structure 4 has a pressure-receiving surface 7 having a height and a wave-like stitch corresponding to a predetermined width of the sheets 2 and 3. By compressing the pressure-receiving surface 7, the sheets 2 and 3 are separated. The cushioning material 1 is formed by bending so as to have an elastic action.

In this embodiment, the corrugated strip sheet 2 and the strip sheet 3 are made of kraft paper or the like. However, one-sided or double-sided corrugated sheet or the like is bent so as to have an elastic action by compression. It is only necessary to keep the state, and the cushioning material 1 is shown to be composed of the corrugated strip sheet 2 and the strip sheet 3, but only the corrugated strip sheet 2 is used, and the ridge lines 4 of these peaks 5 are used. Alternatively, it may be configured such that appropriate portions of the mountain portion 5 are adhered to each other.

Further, the number of corrugated steps of the corrugated strip sheet 2, the height of the crests 5, and the interval between the crests 5 are appropriately set and not limited.

Next, a method of manufacturing the above-mentioned cushioning material will be described. First, a plurality of corrugated cardboard sheets 10 in which one liner 9 is adhered to a core 8 having a corrugated step is stacked and adhered to form a block. Form the body 11.

Next, the block body 11 is cut at right angles to the ridgeline 6 of the core 8 of the block body 11 and with a predetermined width to form a plurality of stitch structures 4 consisting of the corrugated strip sheets 2 and the strip sheets 3. To do.

Then, the cut surface 12 of the stitch structure 4 is formed as a pressure receiving surface 7, and the pressure receiving surface 7 is compressed at a predetermined pressure by a general pressing method using a press roller, a press plate or the like. As a result, the wavy strip sheet 2 and the strip sheet 3 forming the stitch structure 4 are bent and formed so as to have an elastic action to form the cushioning material 1.

In forming the stitch structure 4, a corrugated cardboard sheet 10 having a predetermined width may be previously formed and the corrugated cardboard sheet 10 may be adhered. In this case, a step of forming the block body 11 Will be omitted.

Further, the corrugated board sheet 10 used in the cushioning material 1 according to the present invention is shown to be formed from a single-sided corrugated board sheet, but the present invention is not limited to such a system, and a core is interposed between two liners. It may be formed of a double-faced corrugated cardboard that is adhered as described above, or may be formed by appropriately combining a single-sided corrugated cardboard sheet and a double-sided corrugated cardboard sheet.

Next, the operation of the cushioning material according to the present invention will be explained. The cushioning material 1 holds the bent state so that the corrugated strip sheet 2 and the strip sheet 3 have an elastic action, and the cushioning material 1
The pressure receiving surface 7 has a buffer function.

[0017]

In summary, according to the present invention, a plurality of wavy strip sheets 2 and a plurality of strip sheets 3 are alternately bonded, or a plurality of wavy strip sheets 2 are bonded together, and each sheet 2,
Since 3 is bent to have an elastic action, the elastic action of the corrugated strip sheet 2 and the strip sheet 3 in the bent state can provide the cushioning material 1 having a rich cushioning effect, and the conventional cushioning material made of expanded polystyrene. Unlike, it can be recycled as recycled paper, so it can be used as a substitute for the cushioning material made of Styrofoam, and it is possible to reduce the amount of waste and save resources.

Further, a step of forming a block body 11 by stacking and adhering a plurality of corrugated board sheets 10, and cutting the block body 11 at a right angle to the ridge line 6 of the core 8 of the corrugated board sheet 10 to form a stitch structure. 4 and the step of compressing the cut surface 12 of the stitch structure 4 at a predetermined pressure to bend and form the stitch structure 4 so as to have an elastic action. 1 can be easily manufactured and its added value can be improved, and its practical effect is extremely great.
