DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to an elastic member such as grass,
In particular, the present invention relates to a cushioning member for preventing deformation and breakage of an article with an elastic member using straw.

[0002]

2. Description of the Related Art Conventionally, for example, a shock-absorbing member manufactured by foaming a synthetic resin (such as a styrene resin) prevents deformation or breakage due to vibration or impact during the transportation of an article. The cushioning member manufactured by using the synthetic resin is excellent in mass productivity, moldability, durability, and the like, and has been developed at a phenomenal speed in this century, and the technology has been developed and the consumption has been increased accordingly.
In recent years, buffer members using these synthetic resins have been used in large quantities, and the amount discarded has become enormous.

However, synthetic resin waste does not rust even when exposed to the ground, and does not decompose with light or ozone.
These garbage made the environment worse. In addition, in the case of molded into high foam such as a cushioning member for packing,
Since a large volume is required, the recovery cost is high. Under such circumstances, recycling campaigns have been conducted, but most of the garbage has been incinerated.

[0004]

However, in the incineration plant for discarded garbage, various problems have been raised due to synthetic resin waste. That is, since the synthetic resin has a very strong molecular bond, there is a problem in that high heat is generated at the time of incineration to damage the wall of the incinerator and that a large amount of toxic combustion gas is generated.

Although degradable synthetic resins have been used, degradable synthetic resins have undergone remarkable technological development in recent years, and their consumption tends to increase. However, these degradable synthetic resins are difficult to foam,
There was a problem that the molding took a lot of time and increased the cost.

SUMMARY OF THE INVENTION The present invention has been made to solve the problems of the prior art, and after being used, it is returned to the soil so that it can be decomposed harmlessly and efficiently produced in large quantities. It is an object to provide a buffer member that can be used.

FIG. 4 is a perspective view of the cushioning member 10 shown in FIG.
Are protected by the cushioning member 10 and are packed in the cardboard box 17, respectively.

The cushioning member 10 of the embodiment is, for example, an article 18
It is intended to prevent deformation or breakage due to external force such as vibration or impact due to the movement of the straw, and dry straw 11 as grass (grass may be aya or reeds). And a thread 12 for sewing. The straw 11 is produced in large quantities by harvesting rice and wheat, and has been dried to the extent that it does not lose mold and corrosion due to moisture and does not lose its elasticity due to excessive drying. This straw 11 is only slightly used for compost or feed for livestock after harvesting rice and wheat,
It can be obtained relatively inexpensively with little use elsewhere,
After use, it is returned to the soil and decomposed harmlessly.

The straw 11 is formed by a thin and long stem and leaves (not shown), and the straw 11 is compressed at such a pressure that it does not completely adhere. That is, when a predetermined amount of straw 11 is compressed at a predetermined pressure, the straw 11 is elastically deformed at a predetermined pressure, and is elastically restored when the applied pressure is released. Further, the yarn 12 is made of a plant fiber such as hemp or cotton, and is also decomposed in a pollution-free manner by returning it to soil after use. That is, a predetermined amount of straw 11 is compressed at a predetermined pressure and sewn with a thread 12, thereby providing a predetermined elasticity.

Then, a predetermined amount of straw 11 is arranged in the same longitudinal direction to a predetermined thickness, and further, a predetermined amount of straw 11 in the same longitudinal direction is arranged thereon. In this case, the next straw 11 is arranged by replacing the straw 11 arranged first. This is repeated alternately to stack a plurality of layers, and then compressed to a predetermined pressure by a compression device (not shown). Then, the thread 12 is sewn vertically and horizontally to a predetermined width by a sewing machine (not shown) to manufacture the binding cushioning member 10 (FIG. 1).

In the cushioning member 10, a predetermined amount of the straw 11 is compressed at a predetermined pressure, sewn with a thread 12, and bundled, whereby the straw 11 is arranged in a predetermined shape and compressed. The straw 11 is prevented from being expanded and dispersed. That is, the cushioning member 10 compresses a predetermined amount of straw 11 at a predetermined pressure and binds it with a thread 12 so as to be arranged in a predetermined vertically long and substantially rectangular shape so that an article 18 having a predetermined weight as a whole can be protected. It is configured so that a good buffering property can be obtained.

Then, the thread 12 is sewn on the cushioning member 10 along the shape of an article 18 such as a machine or food (in this case, for example, whiskey contained in a glass bottle). In this case, the thread 12 is sewn in a shape slightly larger than the article 18, and the inside of the sewn thread 12 is cut along a shape of the article 18 by a press (not shown) to provide a cutout portion 13. In such a case, the straw waste 11A of the cutout 13 cut and cut out
Is sealed in a bag 14 of paper or cotton. This is referred to as a buffer member 10A packed with bags 14. That is, the cushioning member 10
Is cut into the shape of the article 18 to form the cutout portion 13,
The straw waste 11A of the cutout portion 13 is packed in a bag 14 to manufacture the cushioning member 10A. As a result, the cushioning member 10A also has a predetermined elasticity.

Then, the cushioning member 10 having no cutout 13 is connected to a box (in this case, a cardboard box) 1 such as a wooden or paper box.
7, a cushioning member 1 having a cutout 13 provided thereon.
Insert 0A. Next, the articles 18 are put in the cutout section 13, the articles 18 are stacked in a plurality of stages, the cushioning member 10 without the cutout section 13 is placed on the uppermost step, and the cardboard box 17 is closed.
If the cardboard box 17 is not turned over or turned upside down, the uppermost buffer member 10 without the cutout 13 may not be placed.

As described above, the article 18 is connected to the cushioning members 10, 1
OA keeps it still. Such article 18
Are held by the cushioning members 10 and 10A having a cushioning property, so that when an external force such as vibration or impact is applied during the transfer movement, the respective cushioning members 10 and 10A are elastically deformed to absorb the external force. it can. Thereby, the article 1
8 can be easily prevented from being deformed or damaged.

Next, another cushioning member 10B will be described with reference to FIG. The other cushioning member 10B, for example, chops the straw 11 to a predetermined size, mixes the adhesive 15, compresses the straw 11 at a predetermined pressure, and leaves it for a predetermined period until the adhesive 15 is hardened. The adhesive 15 is mixed in such an amount that the buffer member 10B can exert a buffering effect by a predetermined impact. Then, the straw 11 is transferred to the article 18.
Molded according to the shape of This makes it possible to manufacture the cushioning member 10 corresponding to various shapes as in the case of the ordinary cushioning member, and to prevent the straw 11 from being dispersed by cutting.

Here, the adhesive 15 is a commercially available one, and its components are starch paste, seaweed, gum arabic, glue, casein, linseed oil, starch derivatives such as acetic acid starch, carboxymethyl starch, methylcellulose, and the like.
Cellulose derivatives such as ethyl cellulose, sodium alginate, locust bean gum, vinyl synthetic paste such as polyvinyl alcohol, vinyl copolymer synthetic paste such as vinyl acetate acrylic acid copolymer, and acrylic synthetic paste such as sodium polyacrylate And natural, semi-synthetic, and synthetic pastes, such as styrene-based synthetic pastes such as styrene-maleic acid copolymer.
If a natural product or a component decomposable material is used as the component of the adhesive 15, the buffer member 10 can be made pollution-free.

The cushioning member 10 with the sheet 16 adhered thereto
FIG. 6 illustrates C. In this case, the cushioning member 10 sewn with the thread 12 and the cushioning member 10 bonded with the adhesive 15
The sheet 16 is adhered and covered around B. In this case sheet 16
Is made of paper, vinyl, polyester, cloth, or the like having a predetermined thickness, and is adhered around the cushioning members 10 and 10B with the same adhesive 15 as described above. Thereby, even if the cushioning member 10C is cut, the straw chips 11A can be handled cleanly without being dispersed from the cut portion, and the precision parts and the article 18 which dislikes dust can be protected from external force such as vibration or impact. can do. Further, since printing or the like can be performed on the surface of the cushioning member 10C, the commercial value can be improved, and it can be used widely and effectively.

On the other hand, FIG.

Will be described. In this case, the end of each cushioning member 10... Is connected to an adhesive 15 or a natural wood or bamboo nail (not shown).
Fix with. Then, an article (not shown) such as a machine or food is directly stored in a buffer member box 19 constituted by the buffer member 10, and the bag 14 is filled in a gap formed between the article 18 and the buffer member box 19. Insert With the cushioning member 10B, the article placed in the cushioning member box 19 is fixed so as not to move.

As a result, the article is stored in the buffer member box 19 and the buffer member 10 (the buffer member 10).
A, 10B, and 10C). Even when an external force such as vibration or impact is applied to the article stored in the buffer member box 19 during movement, the external force is absorbed by the deformation of the buffer members 10A, 10B, and 10C. This makes it possible to easily prevent deformation or breakage of the article.

As described above, the cushioning member 10 uses the straw 11 obtained in large quantities by the production of rice and wheat, compresses a predetermined amount and sew it with the thread 12, or adheres it with the adhesive 15 to give the predetermined buffering. Property is given. This makes it possible to effectively use the straw 11 that has been hardly used, and to manufacture the cushioning member 10 at relatively low cost. In addition, since the cushioning member 10 is decomposed by returning to the soil after use, no pollution such as toxic combustion gas is generated, and it is possible to prevent environmental degradation due to disposal of the cushioning member 10.

Further, since the straw waste 11A of the cutout 13 obtained by cutting the buffer member 10 into the shape of the article 18 is packed in the bag 14 and used as the buffer member 10A, the straw 11 is used.
Can be used without waste. Thus, the cushion member 10 can be used as it is or the straw waste 11A cut into the shape of the article 18 can be used, so that the cost of the cushion member 10 can be significantly reduced.

In the embodiment, the straw 11 is compressed at a predetermined pressure and sewn with the thread 12. However, the present invention is not limited to this. By sewing the thread 12 by changing the compression ratio of the straw 11 depending on the weight of the article 18, The buffer member 10 corresponding to various weights may be used.

Further, the straw 11 in which the adhesive 15 is mixed is prepared by chopping the straw 11 into a predetermined size to form the buffer member 10B having a vertically long and substantially rectangular shape. However, the present invention is not limited to this. Mixing and manufacturing the cushioning member 10 formed into the shape of an article may be performed.

As described above in detail, according to the first aspect of the present invention, the cushioning member protects the article from external force, compresses a predetermined amount of dry grass, adjusts the shape, and increases the predetermined elasticity. Since the structure is applied, even if an external force such as vibration or impact is applied during the transportation of the article, the buffer member can absorb the external force. Therefore, the deformation or breakage of the article can be reliably prevented by the cushioning member using grass, and after use, it is decomposed by returning to the soil, so that no pollution such as toxic combustion gas is generated, and the conventional method is used. It is also possible to prevent environmental degradation due to the disposal of the buffer member as described above.

According to the second aspect of the present invention, since a predetermined amount of grass is sewn and bound with a thread in the first aspect, grass compressed under a predetermined pressure can be bound to a predetermined size. This makes it possible to form grass into an elastic member having a predetermined shape. Therefore, it is possible to prevent the cushioning member from being dispersed, and to stabilize the shape of the elastic member without dispersing since the grass is bound by the yarn.

According to the third aspect of the present invention, in the second aspect, the thread is sewn along the outer shape of the article and the inside of the sewn portion is cut out. The straw does not disperse and can be easily handled. Thereby, it is possible to prevent the waste from adhering to the article.

According to the fourth aspect of the present invention, since a predetermined amount of grass is packed in the bag in the first aspect, a cushioning member can be inserted between the articles so as not to move. As a result, it is possible to put the grass waste cut into an article shape into a bag and use it as a simple cushioning member. Therefore,
The cut grass waste can be used as a buffer member without being discarded, and the cost of the buffer member can be greatly reduced.

According to the fifth aspect of the present invention, the cushioning member protects the article from external force, cuts the grass into a predetermined size, mixes the adhesive, compresses the grass, adjusts the shape, compresses the grass, and adjusts the shape. Since the elastic member is configured to have elasticity, the cushioning member can be formed into a shape conforming to the shape of the article, and the grass can be prevented from being dispersed even when the cushioning member is cut.
Therefore, it can be used in a wide range of fields corresponding to various shapes like a normal cushioning member.

Further, according to the invention of claim 6, according to claim 1,
In claim 2, claim 3, claim 4, or claim 5,
Since straw is used as grass, a large amount of straw obtained from rice and wheat production can be used as a buffer member. This makes it possible to use straw effectively before burning it or turning it into fertilizer, and after use, it is decomposed by returning the cushioning member to the soil. Therefore, a large amount of straw that has not been used can be effectively used.

Further, according to the seventh aspect of the present invention, in the first, second, third or sixth aspect, the straws are laminated so that their longitudinal directions alternate with each other. Even in the case of cutting, it is possible to effectively prevent the cut surface from collapsing and the straw from being dispersed. Thereby, it becomes possible to cut out the straw and manufacture a cushioning member adapted to the shape of the article.

Further, according to the invention of claim 8, claim 1,
Claim 2, Claim 3, Claim 5, Claim 6, or Claim 7
In the above, the sheet is adhered and covered around, so that it is possible to handle cleanly without dispersing straw chips from the buffer member. This makes it possible to protect precision parts and articles that dislike dust, and to perform printing or the like on the surface of the cushioning member. Therefore, it can be used widely and effectively, and the commercial value can be greatly improved.

According to the ninth aspect of the present invention, there is provided the first aspect,
In claim 2, claim 3, claim 5, claim 6, claim 7, or claim 8, since the cushioning member is formed in a box shape, the articles are directly stored in the box and transported. Becomes possible. Therefore, it becomes possible to use both the cushioning member and the packing box, and the labor for storing the cushioning member in a cardboard box or the like can be omitted, and the cost can be significantly reduced.
