Description

Technical Field

[0001] The present invention relates to tableware coated with paint.

Background Art

[0002] Since paints containing harmful environmental hormone substances, heavy metals, etc. may cause health damage, regulations have been strengthened by the Food Sanitation Law. As a conventionally highly safe paint, a tableware or chopstick paint having a natural resin which is a mastic resin and a vegetable oil has been disclosed (see, for example, Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, the paint composition described in Patent Document 1 has a problem that the colors are limited.

[0005] The present invention has been made paying attention to such problems, and an object thereof is to provide tableware having high safety under the Food Sanitation Law and capable of selecting various colors.

Means for Solving the Problems

[0006] The tableware according to the present invention is characterized in that a paint containing a non-toxic pigment, a vegetable oil, and a fatty acid is applied to the tableware body. Since the tableware according to the present invention uses a non-toxic pigment, a vegetable oil, and a fatty acid for the paint, it has high safety under the Food Sanitation Law and can select various colors. In the tableware according to the present invention, a paint in which nanobubbles are generated inside and which contains a non-toxic pigment, a vegetable oil, and a fatty acid may be applied to the surface of the tableware body. In this case, since a paint that generates nanobubbles inside is used, the particles of the paint become small and smooth, making it difficult to form unevenness during painting and enabling uniform painting, and the paint is difficult to peel off.

[0007] It is preferable that silica oil is applied on the paint of the tableware according to the present invention. The tableware according to the present invention may have silica oil applied on a paint that generates nanobubbles inside and contains a non-toxic pigment, vegetable oil, and fatty acid. In this case, due to the particle size difference between the paint particles made smaller by the nanobubbles and the relatively large particles of the silica oil, the silica oil is likely to adhere to the painted surface of the tableware body and is difficult to peel off. In the present invention, it is preferable that the mass ratio of the fatty acid to the vegetable oil is 0.5 to 3. In the present invention, the tableware body may contain bamboo material on the surface to be painted.

Advantages of the Invention

[0008] According to the present invention, it is possible to provide tableware that is highly safe under the Food Sanitation Law and allows selection of various colors.

Embodiments for Carrying Out the Invention

[0010] Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows cutlery which is tableware according to an embodiment of the present invention. The cutlery 1 has a paint applied to the surface of the cutlery body 11, and silica oil is applied on the paint. The cutlery 1 may be any of chopsticks, knives, forks, and spoons, and will be described below by taking chopsticks as an example.

[0011] The cutlery body 11 is made of plant-derived materials, for example, it is made of a chopstick body made of bamboo or wood. The chopstick body is a split chopstick, and the heads 13 of each of the pair of chopstick parts 12 are joined together. Each chopstick part 12 has a tip that gradually tapers. The paint is manufactured by stirring and mixing a non-toxic pigment, vegetable oil, and fatty acid. The paint may be manufactured by stirring and mixing a non-toxic pigment, vegetable oil, and fatty acid with nanobubbles generated inside.

[0012] Examples of non-toxic pigments include mineral pigments that do not contain harmful substances such as cadmium, cobalt, and arsenic, inorganic substances such as calcium oxide, vegetable silica mainly composed of silicon dioxide, plant-derived indigo, and organic pigments such as carmine derived from cochineal insects. Examples of vegetable oils include edible vegetable oils such as linseed oil, sunflower oil, sesame oil, rice oil, olive oil, coconut oil, and cottonseed oil. Examples of fatty acids include saturated fatty acids such as palmitic acid and stearic acid, and unsaturated fatty acids such as oleic acid, linoleic acid, and linolenic acid.

[0013] The mass ratio of fatty acid to vegetable oil is preferably 0.5 to 3. The mass ratio of non-toxic pigment to vegetable oil is preferably 0.001 to 1, particularly preferably 0.3 to 0.5, but it varies depending on the tableware body to be coated. In the painting of the cutlery body 11, a paint is manufactured by stirring and mixing a non-toxic pigment, vegetable oil, and fatty acid, and after the paint is applied to the cutlery body 11, it is dried with hot air at 80 to 100 °C.

[0014] When generating nanobubbles inside the paint, the nanobubbles can be generated by applying air pressure and blowing air using a commercially available nanobubble generator. Examples of painting methods include spraying using a gun spray device, brush painting, dipping, etc. Examples of tableware include cutlery such as chopsticks, as well as soup bowls, trays, balls, cups, lacquer boxes, donburi, plates, etc. Examples of the material of the cutlery body include plastic, wood, bamboo, etc. Hot air drying can be performed using a commercially available hot air dryer.

[0015] Apply silica oil onto the paint of the cutlery body 11 after drying with hot air. As the silica oil, commercially available plant silica oil can be used. Examples of the coating method include spraying using a spray gun device, brush painting, dipping, etc. When nano bubbles are formed, when the silica oil is applied to the dried cutlery body 11, due to the particle difference between the paint particles that have become smaller due to the nano bubbles and the silica oil with large particles, the silica oil is likely to adhere to the painted surface of the dried cutlery body 11. After applying the silica oil, dry it by blowing air or the like.

[0016] When the cutlery body 11 is made of bamboo, since the bamboo contains oil, usually there is a problem that the oil and the paint repel each other, making it difficult to apply the paint and the paint is likely to peel off. However, when the paint is composed of a non-toxic pigment, vegetable oil, and fatty acid stirred and mixed in a state where nano bubbles are generated inside, the paint particles become small and smooth liquid, making it difficult to cause uneven coating and enabling uniform coating, and it is possible to easily perform coating that is difficult to peel off even on bamboo. According to the tableware of the embodiment of the present invention, it has high safety in terms of the Food Sanitation Law and various colors can be selected.

Example

[0017] A paint was produced according to the following formulation, and bamboo-painted chopsticks, which are tableware, were produced. A paint raw material composed of 10 parts by mass of calcium oxide, 500 parts by mass of sunflower oil or linseed oil, and 500 parts by mass of palmitic acid was put into a container and stirred and mixed for 10 minutes. After the well-mixed paint was applied to the bamboo chopsticks by brush painting, the painted chopsticks were dried with hot air at 90 ° C for 30 seconds using a hot air dryer. In this way, the completed bamboo-painted chopsticks had high safety in terms of the Food Sanitation Law and could be dried in a short time by hot air drying.

Example

[0018] A paint was produced according to the following formulation, and bamboo-painted chopsticks, which are tableware, were produced. A paint raw material consisting of 10 parts by mass of calcium oxide, 500 parts by mass of sunflower oil, and 500 parts by mass of palmitic acid was put into a container and stirred and mixed for 10 minutes in a state where nanobubbles were generated inside the paint raw material by a nanobubble generator. After the well-mixed paint was applied to a bamboo chopstick by brush painting, the painted chopstick was dried with hot air at 90 °C for 30 seconds by a hot air dryer. After drying, silica oil was applied once to the dried chopstick by brush painting. After painting, it was dried by a blower for 30 seconds. Thus, the completed painted bamboo chopstick had high safety under the Food Sanitation Law, was uniformly and evenly painted, and could be dried in a short time by hot air drying after painting the paint and air drying after applying silica oil. The painted state of the finished product was a firm paint with strong adhesion to the chopstick and difficult to peel off.
