Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a nail having at least the head surface coated with paint.

(Prior Art) and (Problems to be Solved by the Invention) Conventionally, nails have been coated with paint on the head surface in order to prevent rust. When driving these nails into the material to be driven with an automatic nail gun or manually, the paint on the part that collides with the nail driver or hammer of the nail gun may peel off, causing the nail to be driven into the material. After installation, it is necessary to apply a correction coat to the peeled areas. In addition, some nails have uneven parts formed on the head surface to reduce the peeling area, but with these nails, the screwdriver or hammer collides with the protrusions, causing the paint to peel off from the protrusions. Therefore, correction painting must be performed in the same manner as above. Therefore, with conventional painted nails, correction coating must be applied after driving, which is troublesome and time-consuming, and has poor workability. Another problem is that a large amount of paint must be used in order to perform correction coating.

Therefore, the present invention was devised to solve the above-mentioned problems of the prior art, and its purpose is to provide a nail that does not require correction coating after nail driving.

(Means for Solving the Problems) In order to achieve the above object, in the present invention, a capsule filled with paint is placed in a paint of the same color as the paint on at least the head surface of the nail body. It is constructed by applying a composite paint mixed with it.

(Function) In the present invention having the above configuration, when the surface of the head is struck by a striking member such as a screwdriver or hammer, the capsule in the coated part is crushed and the paint in the capsule oozes out, automatically Perform correction painting.

(Example) The present invention will be explained below based on the illustrated example. FIG. 1 shows an embodiment of the nail according to the present invention,
In the figure, 1 is a nail body, and the nail body 1 has a body part 2 and a head part 3 integrally formed at the rear end of the body part 2. The distal end portion 4 of the body portion 2 is formed into a sharp point. As shown in FIG. 2, the upper surface of the head 3 is coated with a composite paint 10 in which microcapsules 11 each containing a paint are mixed into a paint 12 of the same color as the above paint. It is dried to form a painted surface. The paint 12 has a predetermined viscosity and is in the form of a paste. Here, it is desirable that the paint to be encapsulated in the microcapsules 11 has a high antirust effect.

In the above configuration, when the nail body 1 is driven into the material to be driven with a driver of an automatic nailing machine or a manual hammer, the composite paint 10 is applied to the surface portion of the head 3 hit by the driver, hammer, etc. When the microcapsules 11 are crushed, the paint in the microcapsules 11 oozes out and correction coating is automatically performed to prevent the paint 12 from peeling off.

In the above embodiment, an example was explained in which the composite paint 10 was applied only to the upper surface of the head 3 of the nail body 1 and dried. You can leave it on. In this case, the rust prevention effect on the head 3 can be further improved. Further, the shape of the head 3 of the nail body 1 other than the shape shown in FIG. 1 can also function as a correction coating.

Therefore, in the above embodiment, the paint is sealed in the microcapsules 11, and the microcapsules 11 are filled with paint.
is mixed with paint of the same color to form composite paint 10,
This composite paint 10 is applied to the upper surface of the head 3 and dried.

(Effect of the invention) The nail according to the invention has the above-mentioned structure and function, and since the paint does not peel off after nailing, troublesome and time-consuming correction painting is not necessary, and work efficiency is improved. This results in a significant improvement in the amount of paint used. In addition, there is no appearance defect due to peeling of the paint, and the antirust effect of the paint can be maintained.
