Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention mainly relates to chopsticks used as a substitute for disposable chopsticks in restaurants and the like.

[0002]

[Prior Art]

 Conventionally, disposable chopsticks are generally used in restaurants, etc., but when the disposable chopsticks are made of natural wood such as cedar, bamboo, birch, and aspen to form chopsticks, or when the material is synthetic resin. , Injection molding, compression molding and the like. Typical of the conventional technologies for putting patterns, coloring, and designs on the disposable chopsticks are the disposable chopsticks with the store name by baking, the disposable chopsticks with a pattern that combines the disposable chopsticks and the chopstick bag, and the color disposable chopsticks. (For example, Japanese Utility Model Publication No. 63-178573 and Japanese Utility Model Publication No. 63-133176).

[0003]

[Problems to be solved by the device]

 Among those described in the prior art, the one using natural wood is one of the disposable chopsticks that uses a part of natural wood from the viewpoint of forest protection and the effective use of wood resources due to environmental problems in recent years. There is the problem of being subject to social criticism, which is reported as a symbol of destruction or one-time use. Also, some synthetic resin chopsticks do not rot when buried in the soil during the garbage disposal stage, and there is a risk of generating harmful gas when burned, and high heat may damage the incinerator, and other waste disposal However, there is a problem that it is difficult.

Furthermore, in the restaurant industry of recent years, in order to make the store unique, the interior, furnishings, and eating utensils are also taken into consideration. In this case, it was troublesome and difficult to put the pattern, coloring, and design easily and with high degree of perfection.

In view of the above problems of the conventional technology, the problem to be solved by the present invention is to meet the demands for forest protection, resource saving, and energy saving, and to make waste disposal simple and safe. Furthermore, it is to provide chopsticks that can be easily applied with patterns, colors, and designs that match the atmosphere of individual stores and dishes.

[0006]

[Means for Solving the Problems]

 In order to solve this problem, the chopsticks of the present invention are made of paper, especially recycled paper, and are characterized by using a curable resin to obtain a predetermined hardness. Recycled paper may absorb a large amount of curable resin as it is, so it is preferable to attach a paper on the surface of which the curable resin does not easily penetrate. Any pattern, color and design may be printed on the paper, or the design can be performed by coloring the curable resin.

[0007]

[Action]

 The chopsticks of the present invention do not use any natural wood or synthetic resin for the main body, and use recycled paper made from paper, especially waste paper. Then, in order to obtain the hardness, water resistance, and heat resistance required for the functions of the chopsticks, the chopstick body is coated with the curable resin that is also used for the coated chopsticks to form a curable resin film. .. The curable resin used in the present invention was originally a curable resin paint for preventing the paint on the coated chopsticks from peeling off, and if the curable resin coating can be formed evenly over the entire chopsticks, it can be used for one to three meals. It can be used and can be configured to have hardness, water resistance, and heat resistance.

However, since the paper of the chopstick body is not processed, it has high water absorbency, and it is difficult to form the curable resin film evenly on the surface of the chopsticks. Hardness is also difficult to obtain, and the surface is easily rough. In order to eliminate this and form the curable resin film more reliably, a paper with low penetrability of the curable resin is attached to the front and back of the chopstick body. If the curable resin coating is applied several times on top of it, several layers of curable resin coating can be evenly coated on the entire chopsticks, and sufficient hardness, water resistance and heat resistance can be obtained for the chopsticks. .. Further, a paper on which patterns or patterns are printed may be attached to the paper attached to the entire chopsticks. Further, a color paint may be mixed with the curable resin paint to give a color.

【Example】

 Hereinafter, the present invention will be described in detail based on embodiments. FIG. 1 is a perspective view showing an entire chopstick according to the present invention, and FIGS. 2 and 3 are sectional views showing different embodiments.

In FIG. 1, a main body of a chopstick stick uses paper as a raw material, particularly recycled paper, and a wide area of paperboard made mainly from waste paper, and cuts the paperboard into the shape of disposable chopsticks. Specifically, the cross-sectional shape is approximately square, the length of chopstick sticks A and B is 200 to 245 mm, the thickness is 3.5 to 6.5 mm, and the width is 3.5 to 7 mm. Have a different shape.

In FIG. 2, paper 2 having low permeability is attached to the front and back surfaces of the chopstick body 1 for the purpose of uniformly coating the curable resin coating 3 on the chopstick body 1. This paper 2 can be attached to the paperboard and then cut into the shape of the disposable chopsticks in a step before cutting the paperboard into the shape of the disposable chopsticks. A curable resin film 3 is formed on the paper 2. As the curable resin coating material for forming the curable resin coating 3, a curable resin coating material that is originally used to prevent paint peeling of the applied chopsticks is used. It must be able to withstand temperature, have some rigidity and water resistance, and be nontoxic. Note that FIG. 3 shows an example in which the paper 2 having low permeability is wrapped around the entire circumference of the chopstick body.

As a concrete example of the curable resin coating material, in the epoxy resin system, a two-component Kicoat Top Clear liquid A and liquid B (trade name of Furukawa Paint Co., Ltd.) are mixed at a ratio of 1: 1 to prepare a solution. 10-45% by weight of methanol are used. In the case of the polyurethane resin system, Dream Thinner (trade name of Camus) is added in the range of 10 to 45% by weight to one-pack Dream Clear (trade name of Camus). To the same one-pack Ultrak (Osaka Paint Co., Ltd. product), add Ultrac thinner (Osaka Paint Co., Ltd. product) in a range of 5 to 40% by weight. Polyurethane resin-based two-component Stron Fresh A liquid and Stron Fresh 99B liquid (both are brand names of Camus) are mixed at a ratio of 2: 1, and a dedicated thinner is added in the range of 5 to 25% by weight. Similarly, two-component Stron Ace A liquid and Stron 24B liquid (both are Camus brand names) are mixed at a ratio of 1: 1 and a dedicated thinner is added in the range of 5 to 35% by weight.

The curable resin paint obtained by mixing by the above method can be used as it is as a stock solution, but the penetrability of the material of the paper 2 applied to the chopsticks and the method of applying it to the chopsticks, for example, the dipping method Depending on the brush coating, spraying method, etc., add a thinner or a solvent such as methanol suitable for each curable resin in the above range to prepare the mixture, and then stick the paper 2 on the chopstick body 1 The curable resin coating composition prepared by the above method is applied, and the curable resin film 3 is formed by naturally drying for about 6 to 8 hours, though it varies depending on the curable resin and the preparation method. The above-mentioned curable resin coating materials are merely examples, and it goes without saying that other rigid, water resistant and non-toxic materials can also be used.
