Description

[Detailed description of the invention] The present invention relates to a method for manufacturing painted chopsticks for eating.

Conventional lacquered chopsticks are made by applying paint such as lacquer to the surface of a base material that is formed into the shape of a chopstick and made slightly longer than the complete shape, and then cutting off the unnecessary upper part of this base material. The length of the village was adjusted and paint was applied to the exposed top of the village. For this reason, the bond between the top paint layer formed on the top of the base material and the body surface paint layer applied on the surface of the base material is poor, and the area of the top paint layer is small. There was a drawback in that the adhesion of the coating layer to the top of the substrate was not sufficient, and therefore the top coating layer easily peeled off and fell off.

The present invention aims to provide a method for manufacturing coated chopsticks that can effectively prevent such drawbacks.

The method of the present invention will be explained below with reference to the accompanying drawings.The method of the present invention is to apply lacquer solution or synthetic resin paint to the surface of the base material 1, which is formed into the shape of chopsticks and slightly longer than the finished chopsticks, as shown in Figure 1. The first step is to form the body surface coating layer 2 by applying a paint such as 1
A second step of forming a recessed part, for example, a recessed part 3 in the shape of a gourd, on the top surface lb, and after this second step, applying paint to the top surface lb once or twice or more. As shown in FIG.
step, and after this third step, the top surface coating layer 4 is cut or polished to give a smooth top surface 4' as shown in FIG.
This has a fourth step of obtaining finished chopsticks, and the fixing force of the top coating layer 4 is increased by the recessed portion, and the shape of the recessed portion is exposed on the smooth top surface 4'. It is characterized by In the above, it is preferable that the periphery of the recessed part has an uneven edge, but in some cases, a number of independent circular recessed holes may be formed, or star-shaped recessed parts or striped grooves may be formed. It may be made in a recessed manner, and its shape and depth may be freely selected.

For the top surface lb, the cut end of the base material 1 may be used in its original state, but in some cases, the unnecessary portion la
The cut-off section may be coated with a paint undercoat. In this way, a top surface lb to which the top coating layer 4 is well adhered can be formed on the cut-off section of the base material 1 with a high oil content.

In the method of the present invention, the top surface coating layer 4 is formed by forming a concave portion on the top surface lb of the base material 1 and burying the concave portion. , as shown in FIG. 5, the root portion 4a is embedded in the top and is formed in multiple layers, so that peeling and falling off can be effectively prevented.

Furthermore, according to this method, the top coating layer 4 formed on the top of the base plate 1 becomes thicker at the recessed portion, so that the color of the tube corresponding to the recessed portion is different from other parts. Therefore, the shape of the recessed part, that is, the pattern of the gourd shape in the example can be made to appear on the top surface of the finished product.
This has the effect of not only adding a design element but also displaying the maker.

Claims (1)

[Scope of Claims] 1. A first step in which a paint is applied to the surface of a base material that is molded into the shape of chopsticks and made slightly longer than the finished chopsticks to form a body coating layer, and after the above step, the base material is A second step is to cut off the unnecessary upper part of the material to create a top surface and create a recessed part in this top surface, and after this step, paint is applied to the top surface to bury the recessed part. A method for manufacturing painted chopsticks for eating, comprising a third step of forming a top paint layer, and a fourth step of finishing the top paint layer formed in the above step to a smooth top surface to obtain finished chopsticks. 2. The method for manufacturing painted chopsticks for eating according to claim 1, characterized in that an undercoat is applied to the top portion before forming the recessed portion.
