Abstract

PURPOSE: To easily bury a used bowl in the ground to prevent environmental pollution by using as a material a mixture of powder or granules of fine-milled grain such as buckwheat, buckwheat husks or rice husks and cashew paint and by molding the with the mixture put in a predetermined mold tool and with pressure applied at a high temperature. CONSTITUTION: As a bowl including a semi-spherical container part 1 and a leg 2, a grain such as buckwheat, buckwheat husks or rice husks is used as its material. After the grain is fine-milled into powder or granules having a predetermined size, a mixture of cashew paint which does not contain adverse components and causes no food hygienic problem when painted on tableware is prepared. The material is put into a predetermined mold tool and molded into a bowl. At this time, the material is subjected not only to pressure by the mold tool but also to a high temperature of approximately 160 deg.C to 190 deg.C for molding, the molded bowl is dried, and similar cashew paint is applied on the surface to provide a product.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container formed by using grains such as buckwheat, buckwheat hulls, or fir shells as a material.

[0002]

2. Description of the Related Art In recent years, a great number of plastic molded products have been used in a large amount not only in daily necessities but also in various fields. Further, its applications are expanding more and more, and in order to meet the demands of these various fields, various measures such as improving strength, hardness, elasticity and heat resistance have been made. Further, plastic materials are very often added with other substances as fillers or used in the form of composite materials in combination with other materials.

By the way, most of bowls, plates, bowls, and other bowls, which are one of the daily necessities, are plastic products today. In the past, most wooden lacquer products and pottery were used,
In the case of lacquer ware, due to manufacturing costs and lack of quality wood,
Moreover, wooden lacquer ware and pottery have low durability and have been replaced by plastic ware. As described above, there is a reason for the increase in the number of plastic products, and not only the low cost of the material but also the workability has a great influence.

For these reasons, a large amount of plastic products are manufactured and used today, but used plastic products are disposed of, which causes a serious pollution problem. Since plastic products generate high temperatures and burn, they cannot be incinerated, and even if they are buried in the ground, they cannot semi-permanently stop their shape and return to the soil.

[0005]

The plastic products which are produced and used in large quantities today have the above problems. The problems to be solved by the present invention are these problems. Although the object is a vessel, it can only return to the soil when it is used and disposed of by using natural materials. Provide a container that does not leave any problems in the environment.

[0006]

The container of the present invention is characterized by its material and uses grains such as buckwheat, buckwheat husks, or fir husks. The grains are solidified and molded into a container having a predetermined shape, and a molding die is used for solidification. However, since it is not possible to harden only with grains, paints are mixed and molded into a predetermined shape. or,
During molding, pressure is applied at a high temperature.

The above-mentioned grain is used after being finely crushed, and as the paint functioning as a binder for the grain, cashew paint is used which does not pose any problem when applied to vessels such as tableware for food hygiene. After molding, the paint is applied to the surface of the container to finish it. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a container according to the present invention, and the shape of the container itself is the same as that of the conventional one, and of course, the present invention is intended for all forms of the container, particularly tableware. The container shown in the figure is composed of a hemispherical container portion 1 and a leg portion 2, and the leg portion 2 is integrally formed at the lower end of the container portion 1. A container of such a shape can be easily manufactured by using an injection-molded container made of a conventional plastic material, and occupies most of today's containers.

In the present invention, for example, buckwheat husks are used as a material. Of course, the buckwheat husks are not limited to the above, but may be the contents of buckwheat, and other grains such as fir shells are used. The buckwheat husk may be finely crushed into powder or may be crushed into granules of a predetermined size, which affects the roughness of the surface of the molded vessel. That is, if a powder body is used, the surface becomes a smooth vessel, and if a grain-shaped buckwheat shell is used, it is molded into a slightly rough surface vessel.

However, it is not possible to form a powder having only the crushed buckwheat husks into a container having a predetermined shape, and the paint is mixed when forming. This paint does not contain harmful components, and cashew paint is used, which is not a problem when applied to tableware for food hygiene. That is, a mixture of finely crushed buckwheat shells and the coating material is put into a predetermined mold and molded. In this case, not only pressurization by the mold, but also about 160 ℃ ~ 1
Mold at a high temperature of 90 ° C.

FIG. 2 shows a concrete example of molding the container with a mold. The mold is composed of a lower mold 3 and an upper mold 4, and the lower mold 3 has a concave portion having the outer surface shape of the container. In addition, the upper mold 4 is a convex portion of the inner surface shape of the container. Of course, this is the basic form of the mold, and the material in which the buckwheat shell and the paint are mixed is put in the recess of the lower mold 3 and the upper mold 4 is lowered to compress the material. In this case, the lower die 3 and the upper die 4 are attached to the heaters 5 and 5, respectively.
And is kept at a predetermined high temperature.

The amount of material to be put in the lower mold 3 must be necessary and sufficient for molding a predetermined container, and therefore, if the material put in the lower mold 3 has an extra amount, the lower mold 3 is required. And flows into the gap between the upper mold 4 and is removed as a kind of burr after molding. Then, the molded container is removed from the mold and dried, and cashew paint is also applied to the surface thereof.
Of course, not only can the paint be applied to the surface, but the required pattern can also be drawn, which is the same as in the case of conventional plastic products.

By the way, the container of the present invention is a molded product made of grains such as buckwheat hulls, but leaves or the like can be attached to the surface of the container during molding. That is, if the leaves of the tree are set at a predetermined place and the upper mold 4 is lowered and compressed, the leaves are fixed to the surface of the container to be molded and form a kind of pattern. This has a different taste from the pattern drawn with color paint. As described above, the container of the present invention is made of grains as a material, mixed with a paint and molded at a high temperature, and the following effects can be obtained.

[0014]

The container of the present invention uses grains such as buckwheat husks, and therefore, even if it is used and disposed of, it will eventually become soil, causing pollution problems such as plastic products. do not do. Of course, you can incinerate, but you don't have to incinerate. In addition, the container made of cereals is suitable as a container for Japanese cuisine, for example, when used as a container for buckwheat in a buckwheat shop etc., the container and buckwheat are compatible,
It will enhance the goodness of buckwheat from the side.
