As shown in the overall view of FIG. 1, the applicator 10
Includes a holding member 20, a coating member 40, and a container 50. The coating member 40 is an elongated plate-shaped member, and a portion 43 near one long side 42 thereof is exposed to the outside. The container 50 contains a coating liquid (for example, a UV-cut glass coating agent applied to the glass surface) to be supplied to the coating member 40. While holding the container 50 and allowing the coating liquid to penetrate the coating member 40, the coating member 40
By moving the applicator 10 relative to the surface to be coated while pressing on the surface to be coated, the coating liquid can be evenly applied to the surface to be coated.

The holding member 20 has a holding portion 22 for holding the coating member 40 and a container mounting portion 24 for mounting the container 50.

As shown in the sectional view of FIG. 2, a coating member insertion groove 30 extending in the longitudinal direction is formed in the holding portion 22, and the other long side 44 side of the coating member 40 is inserted. The width of the coating member insertion groove 30 is formed to be smaller than the thickness of the coating member 40. By pressing the coating member 40 into the coating member insertion groove 30, the coating member 40 is sandwiched between both side surfaces of the coating member insertion groove 30. The application member 40 is fixed. For example, the holding member 20 is made of resin so that the peripheral portion of the coating member insertion groove 30 is elastically deformed.

An inclined surface 23 forming a predetermined angle α with a portion 43 near one of the long sides 42 of the coating member 40 exposed to the outside is formed at the end of the holding portion 22, and the coating member 40 is coated with the inclined surface 23. The applicator 10 does not interfere with the surface to be coated even when pressed in an inclined state. Coating member 40
The predetermined angle α is preferably 120 degrees or more so that it can be tilted about 45 degrees with respect to the surface to be coated.
It is 45 degrees or less, and more preferably around 135 degrees. The length H of the exposed portion 43 of the coating member 40 is preferably about the same as the thickness of the coating member 40, for example, 3
It is about mm.

Between the coating member insertion groove 30 and the container mounting portion 24, there is a flow path (a communication hole 2 to be described later) for flowing the coating liquid.
8, the communication groove 38 and the through hole 36) are formed.

For example, the coating member inserting groove 30 is provided on the side opposite to the coating member inserting groove 30 (the lower side in FIGS. 1 and 2).
A continuous extension groove 32 is formed on the bottom surface of the, and the insertion member 34 is inserted into the extension groove 32.

As shown in the sectional views of FIGS. 2 and 3, the insertion member 34 is connected to a plurality of through holes 36 having one end open to the coating member insertion groove 32 side and the other end side of the through hole 36. A communication groove 38 is formed. A communication hole 28 is formed between the extension groove 32 and the container mounting portion 24 so that the communication groove 38 and the hollow hole 26 of the container mounting portion 24 communicate with each other.

By using the insertion member 34, it is easy to form the flow path, and the dimensions of the through hole 36 and the communication groove 38 are
The flow rate can be adjusted by simply replacing the insertion member 34 with a different shape or arrangement.

By providing a liquid reservoir at an appropriate position in the flow path, the coating liquid can be stably supplied to the coating member 40. For example, the other end side (the lower side in the drawing) of the through hole 36 is enlarged in a conical shape and the cross section in the direction perpendicular to the flow path is partially enlarged to provide the liquid storage portion.

As shown in FIGS. 1 to 3, the container mounting portion 24
Has a hollow hole 26 into which the one end 50a side of the container 50 is inserted, and an inner screw 27 is formed on the inner peripheral surface.

The container 50 is, as shown in the enlarged view of FIG.
One end 50a is sealed with a sealing plug 62, and an outer screw 52 is formed on the outer peripheral surface near the one end 50a. A cap 60 (only the outer shape is shown by a chain line) that is screwed to the outer screw 52 is attached to the one end 50a side of the container.

As shown by the chain line in FIG. 1, the outer peripheral surface of the intermediate portion of the container 50 may be provided with irregularities so that it can be easily gripped by hand. The container 50 is made of, for example, resin so as to have appropriate elasticity, and the container 50 is dented so that the coating liquid can be pushed out to the outside.

The container 50 includes a cap 60 and a sealing stopper 62.
After removing, the one end 50a side is inserted into the hollow hole 26 of the container mounting portion 24 of the holding member 20 and rotated, and the outer screw 52 of the container 60 is screwed into the inner screw 27 of the container mounting portion 24. Then, as shown in FIG.
Is in contact with the end surface 25 of the container mounting portion 24, the container 5
0 is fixed to the holding member 20. The container 50 is attached to the container mounting portion 2
An appropriate seal member, for example, an O-ring arranged on the stepped portion 54 of the container 50 may be used for more airtight connection with the container 4.

The container 50 may have a straight shape, but as shown by the chain line in FIG. 1, the one end 50a side and the other end 50b side may be curved in a substantially V shape. If the container 50 has a curved shape, the container 50 used as the grip portion can be arranged at an appropriate angle so that the application work can be easily performed.

If the container 50 is curved and the projection 56 is provided, the mounting angle of the container 50 can be changed. That is, as shown in FIG. 4, a plurality of protrusions 56 are provided on the step portion 54 of the container 50 at appropriate intervals. Then, by rotating the container 50 until the protrusion 56 contacts the end surface 25 of the container mounting portion 24, for example, as shown by the solid line in FIG. 1, the other end 50b side of the container 50 with respect to the longitudinal direction of the coating member 40. The container 50 is fixed so that it becomes a right angle. Further, by forcibly rotating the container 50, indenting the protrusion 56 of the container 50, and rotating by, for example, 90 degrees until the entire step portion 54 comes into contact with the end surface 25 of the container mounting portion 24, this is indicated by a chain line in FIG. Thus, the container 50 is fixed so that the other end 50 b side of the container 50 is inclined with respect to the longitudinal direction of the coating member 40.

As the coating member 30, a resin having a porous continuous pore structure such as a sponge or sponge, or a material such as a non-woven fabric into which the coating liquid easily penetrates is used.

For example, poly vinyl alcohol (P
A sheet-shaped sponge member formed by chemically reacting (VA) with a chemical reaction (acetalization) is used after being cut to an appropriate size.
This poly / vinyl / acetal resin is excellent not only in water absorption but also in abrasion resistance and chemical resistance. Further, since it is hardened in a dried state, it is easy to handle, and the holding member 20 can be easily attached to and detached from the coating member insertion groove 30.

Next, a method of using the applicator 10 will be described.

First, the coating member 40 and the container 50 are attached to the holding member 20, and the container 50 is dented so that the coating liquid permeates the coating member 40. The coating liquid discharged from the container 50 passes through the communication hole 28, the communication groove 38, and the through hole 36, reaches the coating member 40 through the opening 37 (see FIG. 3) of the through hole 36, and permeates the coating member 40. By arranging the through holes 36 at appropriate intervals, the coating liquid can be uniformly permeated into the coating member 40.

While holding the container 50 of the applicator 10 and pressing one long side 42 of the coating member 40 against the surface to be coated, while holding the coating member 40 at an appropriate angle with respect to the surface to be coated, The applicator 10 is moved relative to the surface to be coated in the direction perpendicular to the longitudinal direction of the coating member 40. As a result, the coating liquid can be applied to the surface to be coated from the long side 42 of the coating member 40.

By continuously applying the coating liquid that uniformly penetrates the coating member 40, the coating can be performed easily, efficiently and evenly.

The present invention is not limited to the above embodiment, but can be implemented in various other modes.

For example, the flow path may be formed integrally with the holding member 20 without forming the structure in which the insertion member 34 can be separated. Further, the container 50 may be used only as a gripping part and may not contain the coating liquid.

Furthermore, the container 50 and the grip portion may be eliminated and the application member 40 may be held. The coating liquid may be appropriately supplied to the coating member 40.

The long side on the coating side of the coating member is not limited to a straight line, but can be appropriately shaped according to the surface to be coated.
Further, the application member is not limited to a flat surface and may be curved, for example. The holding member may be appropriately formed according to the shape of the coating member.

Further, since the applicator of the present invention uses the water-absorptive coating member, it can be used for wiping and removing liquid.
