Description

The present invention relates to a coating tool for painting a floor surface, a wall surface, or the like by rotating a coating roller impregnated with a paint with a surface to be painted, and a painting method using the coating tool.

Conventionally, in a general hand-painting tool, a grip portion is provided at one end of a shaft member and a coating roller is provided at the other end so as to be rotatable and detachable. , While pressing the coating roller against the surface to be coated such as a wall surface, it rotates and reciprocates to paint. After that, when the paint runs out, the coating roller is dipped in the paint again, and the painting is repeated.

By the way, in the above-mentioned general coating tool, since the coating roller is dipped in the paint to replenish the paint, the work is complicated and burdens the operator. On the other hand, for example, as disclosed in Patent Document 1, a coating tool in which a storage member for storing paint is provided inside a coating roller has been proposed. In the coating tool disclosed in Patent Document 1, when a coating roller is pressed against the surface to be coated when the surface to be coated is painted, the paint held in the storage member is extruded and passed through the paint supply flow path. Since it is supplied to the coating member, the number of times the coating material is supplied to the coating roller can be reduced.

However, in the coating tool disclosed in Patent Document 1 described above, the coating supply flow path is formed over the entire length of the coating roller, and the coating material exudes from the entire coating supply flow path at once. If the coating roller is tilted at this time, there is a problem that the paint collects on the lower side. Therefore, there is a possibility that uneven coating may occur depending on the usage condition of the coating roller.

Therefore, the present invention solves the above-mentioned problems, and when a coating roller impregnated with a paint is brought into rotational contact with a surface to be coated to paint a floor surface, a wall surface, or the like, the coating roller is applied. It is an object of the present invention to provide a coating tool capable of saving labor in supplying the coating material and reducing unevenness in coating, and a coating method using the coating tool.
