案した。(Prior Art) As shown in FIG. It is formed into a cup shape and shrinks and deforms when heated in a baking drying oven, and when undercoat is applied to the lower surface of a floor panel a of an automobile body, for example, the water that forms on the panel a. The masking body 1' is designed to prevent paint from entering holes b such as extraction holes and screw holes and staining the interior of the car.
The masking body 1' is fitted into these holes b in advance, and when the coating film c is baked and dried, the masking body 1' is caused to naturally fall off due to contraction and deformation in the oven.

の孔bだけになる。(Problem to be solved by the invention) In the above, the cup part 2' of the masking body 1' is tapered to facilitate insertion into the hole b, and the lower end of the cup part 2' on the side of the flange part 3' is tapered. Generally, the outer diameter of the main body 1' is made slightly larger than the hole diameter, and the end of the main body 1' is press-fitted into the hole b as shown in FIG. It is also possible to fit the main body 1' in the middle of the cup part 2' as shown, but if the main body 1' is pushed strongly in this state, the whole main body 1' will be crushed, so the cup part 2' The main body 1' can only be pushed in to the extent that the peripheral surface lightly contacts the edge of the hole b, and the main body 1' is less likely to bite into the hole b, making it easier to fall off. Only hole b of a predetermined diameter can be used.

とする。(Means for Solving the Problems) In order to achieve the above object, the present invention, in the above-mentioned proposal, creates a step between the outwardly projecting convex portions on the circumferential surface of the cup portion of the masking body. The main body is formed in a plurality of upper and lower stages, and the main body can be fitted into holes having different diameters at the convex portions of each stage.

面状に戻ろうとして収縮変形する。 Referring to FIGS. 3 and 4, 1 denotes a masking body, which has a flange-shaped cup shape consisting of a cup portion 2 and a flange portion 3 on the open end side thereof, and is heated in a baking drying oven. In this case, the main body 1 may be formed of a heat-shrinkable synthetic resin, but high-impact styrene, polystyrene, hard vinyl chloride, polypropylene, polyethylene, etc. 0.2mm~
The main body 1 may be formed by using a 2 mm thick thermoplastic synthetic resin film, heated to a temperature above the softening point and below the melting point, and then drawn and rapidly cooled. Internal stress due to drawing forming remains in the main body 1, and when the main body 1 is heated in a furnace, the internal stress causes the main body 1 to contract and deform in an attempt to return to the shape before forming, that is, a planar shape.

To explain this in more detail, in the case shown in FIGS. 3 and 4, the cup portion 2 is tapered, and there are grooves at multiple points around the circumference from the middle in the generatrix direction to the collar portion 3. The convex portions 4 were formed in three stages, upper and lower. Note that the shape of the convex portion 4 is not limited to this; for example, as shown in FIGS. 5 and 6, the annular convex portion 4 may be formed in multiple upper and lower stages over the entire circumference of the cup portion 2. good.

縮変形で確実に孔bから脱落する。(Function) When painting, the masking body 1 is fitted in advance into the hole b of the object to be painted a. In this case, when the hole b has a small diameter, the hole diameter is When the size is large, the main body 1 is press-fitted into the hole b at the middle protrusion 4, and each protrusion 4 bites into the hole b to prevent the main body 1 from falling out of the hole b. When the upper and middle convex parts 4 are fitted into the holes 4 in this way, the flange part 3 separates from the painted surface, and the flange part 3 moves away from the paint film c on the painted surface.
In addition, the flange 3 prevents the paint from getting caught in the hole b side, and prevents the paint from adhering to the fitting part between the hole b and the main body 1. Therefore, when the object to be coated (a) is placed in a baking drying oven and heated, the masking body 1 reliably falls out of the hole (b) due to its contraction and deformation.
尚、マスキング本体1をその下段の凸部4にお
いてより大きな孔径の孔に嵌合させることも可能
であるが、かくするときは鍔部3が塗装面に接触
するため、かかる孔にはマスキング本体1として
より大きなものを用いた方が良い。 It is also possible to fit the masking body 1 into a hole with a larger diameter at the lower protrusion 4, but in this case, the flange 3 comes into contact with the painted surface, so the masking body 1 cannot be fitted into such a hole. It is better to use a larger one as 1.

This makes it possible to fit the masking body into the hole so that the masking body does not come into contact with the painted surface of the object to be painted, and the masking body can be applied to a wider range of applications. This has the effect of ensuring that the material does not fall off.
