Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to paper having water resistance and fire resistance, and containers such as pots made of the paper.

[Prior Art] Conventionally, it has been known to form containers such as pots by subjecting relatively thin paper to certain processing using special materials such as ceramics and glass fibers. Compared to general metal pots or earthenware pots, they have the advantage of being lighter, having a better appearance, and being disposable.

[Problems to be Solved by the Invention] However, since the above-mentioned simple pot uses ceramics, glass fiber, etc. as materials that provide water resistance and fire resistance to the paper, manufacturing thereof is complicated and costly. I've come across a problem.

The present invention solves the above-mentioned problems, uses readily available food materials to impart water resistance and fire resistance to paper, and provides containers such as pots made using the paper. purpose.

[Means for Solving the Problems] According to the present invention, starch and at least one mixture selected from a mixture of egg white and vinegar, a mixture of egg yolk and vinegar, and a mixture of egg white, egg yolk, and vinegar. A water- and fire-resistant paper is provided by applying a mixture of the above to a relatively thin paper and drying the mixture.

In the paper according to the present invention, a mixture of egg white and vinegar, a mixture of egg yolk and vinegar, and a mixture of egg white, egg yolk, and vinegar penetrate between the pulp fibers constituting the paper, and the starch is uniformly spread over the surface of the paper. It adheres as a powder and covers it.

According to the present invention, the comparative product is further coated with a mixture comprising starch and at least one mixture selected from a mixture of egg white and vinegar, a mixture of egg yolk and vinegar, and a mixture of egg white, egg yolk and vinegar. A water-resistant and fire-resistant paper container is provided by forming thin paper into a desired container shape and drying it.

In the paper container according to the present invention, a mixture of egg white and vinegar, a mixture of egg yolk and vinegar, or a mixture of egg white, egg yolk and vinegar penetrates between the pulp fibers constituting the paper, and the outer surface is coated with starch. is deposited and covered as a uniform powder.

The paper container according to the present invention can be easily manufactured with good reproducibility and yield by forming paper coated with the mixture into a container shape using a pot-shaped wire mesh as a template.

The paper used as a material in the present invention is preferably relatively thin paper, especially Japanese paper, which is easily penetrated by a slimy mixture.

[Function] The paper according to the present invention is a relatively thin paper containing at least one mixture selected from a mixture of egg white and vinegar, a mixture of egg yolk and vinegar, and a mixture of egg white, egg yolk, and vinegar, and starch. The paper coated with the above mixture has the following properties:
It can be formed into a pot shape and retains its shape even when dried.

When the paper container thus obtained is fitted into a wire mesh container and heated with hot water, the paper container fits tightly into the wire mesh container, resulting in a pot with sufficient strength. Even if a small amount of hot water leaks from the wrinkled area of the paper, the leak will gradually stop, and the pot will withstand stimulation from the ingredients and chopsticks placed in the pot, allowing you to cook for several hours.

A paper container obtained by applying at least one kind of mixture selected from a mixture of egg white and vinegar, a mixture of egg yolk and vinegar, and a mixture of egg white, egg yolk, and vinegar onto relatively thin paper and drying the mixture. In other words, if the above mixture lacks starch, it will not adhere well to the wire mesh container and will not be strong enough, and if the hot water starts leaking from the wrinkled area of the paper, it will not stop naturally. I can't continue cooking. Furthermore, even if hot water does not leak at the beginning, irritation from ingredients placed in the pot or chopsticks may cause leakage, making it impossible to continue cooking.

On the other hand, in paper containers obtained by mixing starch with water and applying the mixture, the starch easily peels off, and when hot water is poured into the container and heated, the water leaks, making it impossible to put it to practical use.

[Example] Next, the present invention will be explained in more detail with reference to Examples and Comparative Examples.

EXAMPLE FIG. 1 shows a Japanese paper 1 to be provided with water resistance and fire resistance according to the present invention. Japanese paper 1 is made from kozo (Japanese mulberry tree) and manufactured using an old traditional method, and is thinner than ordinary paper and has the property of being more easily penetrated by liquids.

The method for imparting water resistance and fire resistance to Japanese paper 1 is as follows:
It is as follows.

First, prepare a mixture of egg white, a familiar food, and vinegar. The mixing ratio is 1 to 2 teaspoons of vinegar to the white of one egg. In addition, a mixture of egg yolk and vinegar, or a mixture of egg white and egg yolk and vinegar added may also be used. Furthermore, instead of vinegar, acetic acid that can be purchased at a pharmacy may be used, in which case it is used as an aqueous solution with a concentration of about 3%.

Next, approximately the same amount of starch is added to the above mixture and the two are mixed to form a viscous mixture. As the starch, for example, potato starch can be used. In addition, in order to increase the adhesion of this mixture to Japanese paper, a small amount of paste-like cooked rice grains may be mixed in.

The viscous mixture thus made is applied to Japanese paper 1 using a brush or other means, as shown by reference numeral 2 in FIG.
Apply it to the surface and let it soak in thoroughly. At this time, in order to further strengthen the water resistance of the Japanese paper 1, it is preferable to sprinkle a small amount of konjac powder on the coated area 2 of the mixture before it dries. However, this is not always necessary.

When the coated area 2 of the Japanese paper 1 coated with the above-mentioned mixture dries, it prevents water from penetrating and becomes resistant to fire, resulting in water resistance and fire resistance. Moreover, since the mixture consists only of food, it is harmless to the human body.

Therefore, by utilizing this property, it is possible to make the following Japanese paper pot.

That is, as shown in FIGS. 3 and 4, the Japanese paper 1 coated with the above-mentioned slimy mixture is placed on a desired pot-shaped mold material 3 with the mixture-applied portion 2 facing outside, and shaped into a pot. Set aside and let dry.
In this case, the mixture application portion 2 of the Japanese paper 1 is made large enough to almost cover the mold material 3. Further, the mold material 3 may be a commercially available container such as a pot, but if you use a wire mesh formed in the shape of a pot as shown in the figure, the mixture-applied portion 2 of the washi paper 1 can be dried evenly and evenly. , paper containers that can be used as cooking pots can be manufactured with good yield.

The Japanese paper 1 shaped into the container shape described above constitutes a Japanese paper pot by placing the mixture application part 2 inside the wire mesh container 4 as shown in FIG. As shown in FIG. 6, cooking in a pot can be done by pouring boiling water into a Japanese paper pot 5 supported by a wire mesh and heating it from below with an appropriate fire source 6. At this time, the mixture-applied portion 2 of the Japanese paper 1 fitted in the wire mesh container 4 has durability against hot water and fire for at least several hours due to the characteristics of the mixture described above, and can be fully used as a pot. Furthermore, since the mixture application part 2 of the Japanese paper 1 is located on the outside, the mixture does not directly mix with the food such as vegetables put in the pot, and does not impair the taste of the dish.

Comparative Example 1 1 to 2 teaspoons of vinegar was added to the egg white of one egg to the Japanese paper made by traditional methods using the mulberry tree used in the example as a raw material, and the mixture was mixed until it became uniform. The mixed solution prepared by stirring was applied, and a mold was made using the mold material 3 used in the example.

The resulting paper container was fitted into a wire mesh container 4 and heated with hot water, but the paper container did not conform well to the wire mesh container. In addition, hot water leaked from the wrinkled areas, and even if heating continued, the leakage did not stop, making it impossible to continue cooking. Even if there was no leakage at first, it started leaking while adding ingredients or stirring with chopsticks, making it impossible to continue cooking.

Comparative Example 2 A mixture of potato starch mixed with water was applied with a brush to Japanese paper made by a traditional method using the mulberry tree used in the example as a raw material. The water was absorbed by the Japanese paper, and the potato starch remained in a layer on the surface of the Japanese paper. While the Japanese paper was still wet, it was molded using the molding material 3 used in Examples, but the potato starch flaked off from the surface of the paper.

When a paper shaped like a container was fitted into a wire mesh container 4 and hot water was poured into it, the hot water did not stay in the paper container and all leaked out.

Although the above embodiments have been described, the present invention is not limited thereto. For example, in the case of a pot made from Western paper, which is difficult for the above mixture to permeate, it is preferable to first pour boiling water into the pot, wait for about 3 minutes, and then start heating it with an appropriate heat source. Further, as a method for applying the above-mentioned mixture to paper, a method such as dipping the paper into the mixture may be used as necessary.

[Effects of the Invention] As described above, according to the present invention, water-resistant and fire-resistant paper can be made using only food materials that are harmless to the human body and are easily available on a daily basis. expands. In addition, containers such as pots made using this paper have an atmosphere and emotion that cannot be achieved with metal pots or clay pots, and when traditional Japanese paper is used, it goes well with hot pot dishes, promoting the use of Japanese paper. You can get the effect that you can.
