Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a coating roller used for coating the entire surface of a roller with coating and rotating the roller.

(Prior Art) The conventional coating roller shown in FIGS. 4 and 5 has a brush portion 2 made of pure bristles or synthetic fibers around a synthetic resin tube 1.
Is attached to form the roller body a.

The axial length of the brush portion 2 is slightly longer than the axial length of the tube 1. This long brush part 2
The excess part 2a of is folded back and put in the pipe 1,
The plug 3 is forcibly pushed into the central portion so that the excess portion 2a does not protrude from the pipe 1.

Moreover, the plug 3 is left exposed at the end of the roller body a.

(Problems to be Solved by the Present Invention) In the conventional coating roller as described above, the plug 3 is exposed at the end of the roller body a, so it is possible that the coating is sufficiently contained in this portion. Can not. Therefore, for example, when the roller is rolled along the corner of the wall surface, there is a problem that the corner cannot be painted.

It is an object of the present invention to provide a painting roller in which the end portion of the roller body can also contain sufficient paint.

(Means for Solving Problems) This invention is premised on a coating roller in which a brush body made of pure bristles, synthetic fibers or the like is provided around a pipe to form a roller body.

Then, on the premise of the above-mentioned coating roller, the present invention makes the axial length of the pipe shorter than the axial length of the brush portion, and folds back the brush portion protruding outward from this pipe. It has a feature in that it is pressed into.

(Operation of the present invention) The present invention has a push-in portion provided outside the brush portion, press-fits this push-in portion into the pipe, and prevents the push-out portion from protruding from the pipe due to the volume of the push-in portion. The end portion of the roller body can be completely covered with the brush portion.

(Effect of the present invention) According to the coating roller of the present invention, since the end portion of the roller body can be completely covered with the brush portion, the end portion can be sufficiently filled with the coating material. Therefore, by applying the end of the roller body to the corner of the wall surface, the corner and the like can be coated all at once, and the trouble of separately finishing the corner with a brush or the like is eliminated.

(Embodiment of the Invention) In the embodiment shown in FIGS. 1 to 3, the brush portion 5 similar to the conventional one is attached to the outside of the paper tube 4, but the length of the paper tube 4 in the axial direction is It is considerably shorter than the brush part 5.

However, in the actual manufacturing process, as shown in FIG. 2, the brush portion 5 is attached over the entire length of the paper tube 4 in the axial direction, and thereafter, only the unnecessary portion 4a of the paper tube 4 is removed by a drill-shaped tool. I try to scrape it off.

Of the brush portion 5 configured as described above, a portion that is longer than the paper tube 4 is used as a push-in portion 5a. The push-in portion 5a is folded back and press-fitted into the end portion of the paper tube 4 as shown in FIG. ing. By thus press-fitting the push-in portion 5a into the paper tube 4, the push-out portion 5a is prevented from protruding.

In addition, as described above, by simply press-fitting the pushing portion 5a,
To prevent the protrusion, the pressing portion 5
A needs a sufficient volume. Since this volume is determined by the length of the pushing portion 5a, the length of the unnecessary portion 4a to be shaved off must be sufficiently long in this embodiment. In other words, the length of the paper tube 4 in the axial direction is made sufficiently shorter than the length of the brush portion 5 in the axial direction, and the volume of the pushing portion 5a prevents it from protruding from the paper tube 5. There is.

Reference numeral 6 in the drawing denotes a shaft for rotatably supporting the roller body a, and a handle (not shown) is attached to the tip of the shaft.

Since the end portion of the above-described coating roller can be coated with the coating material, if the end portion is moved along the corner of the wall surface, the corner can be coated at the same time.
