Abstract

(57) [Abstract] [Purpose] To provide a cushioning material that can be incinerated without any problem, can be used in lump units without scattering, and can be finely adjusted in quantity. [Structure] A waste paper is used as a material, a plurality of corrugated portions 1 are provided by a stage machine, a plurality of kerfs 2 are formed in a direction perpendicular to the wavy lines of the corrugated portion 1, and both ends of the kerfs 2 are not cut and are not cut. Provided as 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is useful for packing fragile items.
The present invention relates to a cushioning material to be used by filling it in a gap.

[0002]

2. Description of the Related Art A conventional cushioning material is a foamed resin foam or a paper sheet cut into long and thin pieces.

[0003]

The conventional foamed resin products have problems such as toxic gas being emitted at the time of incineration and burning at a high temperature, which damages the furnace. There was a problem that it was easy to scatter with paper objects cut into strips. The present invention has been made to solve the problem that there is no problem during incineration and that it can be handled without scattering.

[0004]

In order to solve the above-mentioned problems, the cushioning material of the present invention has a corrugated portion formed in a corrugated sheet through a paper sheet having a moderate elasticity and a shape memory property in a tiering machine used for making corrugated cardboard. A plurality of cut grooves are provided in a direction perpendicular to the wave streaks of the corrugated portion, the regions separated by the cut grooves are provided as wave bands, and both ends of the cut grooves are left uncut and provided as uncut areas.

[0005]

The cushioning material constructed as described above has a cushioning effect due to the presence of the corrugated portion, and the presence of the kerf causes the corrugated sheet to become a narrow corrugated band, spread apart, and have an uncut area. , The wave band is not scattered and can be handled as a single lump.

[0006]

EXAMPLES Examples will be described with reference to the drawings.
In FIG. 1, a moderately flexible paper sheet having shape memory is used, and this paper sheet does not use a brand-new product but uses a used product or waste paper. A plurality of corrugated portions 1 are provided by passing a paper sheet through a stacking machine, and a plurality of kerfs 2 are formed in a direction perpendicular to the corrugations of the corrugated portion 1. These kerfs 2 are used for a punching machine for processing a paper sheet. The cutting is performed by applying a number of cutting blades and pressurizing, and the region separated by the cutting groove 2 is provided as a wave band 3. The cutting blade of the punching machine does not reach the ends of both ends of the paper sheet, and the area left uncut by the cutting blade is uncut.
It is provided as.

In FIG. 2, the product of the present invention is used by folding it in multiple layers or rolling it into a crumple, and the presence of the corrugated portion 1 causes a cushioning effect, resulting in a cut groove 2.
As a result, the thin wave bands 3 are separated from each other, and by folding the present invention, the wave bands 3 overlap each other or intersect each other, so that the fluffy elasticity is further increased and the uncut area 4
Since the wavebands 3 are continuous at the point of, they can be handled as one lump unit without being scattered.

In FIG. 3, the product of the present invention can be used even in a bare state, but the wave band 3 has an edge part partially hard due to the presence of a wave, so that the envelope 5 The present invention is put in the bag 6 and used for the purpose of covering up these problems, since it may be scratched, and it is unsightly because it is printed because it is made of waste paper. .

In FIG. 4, the present invention is used in a state of being put in a bag 6, the object 5 is put in a box 7, and then the bag 6 is put in a gap between the box 7 and the present invention. The object 5 is pushed in to firmly fix the envelope 5.

[0010]

Since the material is waste paper, there is no problem even if it is incinerated, and resources can be effectively used. There are wavy parts,
It has a sufficient cushioning property because it is folded in multiple layers, it becomes soft when used in a bag, and it may be printed because the material is waste paper, so cover it up. To improve the appearance. Due to the presence of uncut areas, the wave band is not scattered and scattered, and it can be handled in chunks. Also, the amount can be finely adjusted by cutting off the uncut area.

Claims (1)

[Claims] 1. A plurality of corrugated portions 1 are provided by a stepping machine by using a paper sheet having an appropriate rigidity and easy to remember the shape, and a plurality of cut grooves 2 are formed in a direction perpendicular to the mountain lines of the corrugated portion 1. Provided,
The region separated by the kerf 2 is provided as a wave band 3,
A cushioning material provided as an uncut area 4 by leaving both ends of the kerf 2 without separating.
