Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a coating sheet.

[0002]

2. Description of the Related Art Conventionally, for example, when painting a wall surface, there is a case where a surface to be coated and a non-painting surface of the wall surface are separated by a boundary line and only the surface to be coated is painted. In this case, a coating sheet called a masking sheet is attached along the boundary line between the both surfaces to cover the non-painted surface, and the paint sheet prevents the paint from adhering to the non-painted surface.

In order to stick the above-mentioned coating sheet, first, a first tape called a discard tape is extended along the boundary line between the both surfaces, and the edge portion of the first tape is aligned with the boundary line. Glue the first tape over the unpainted surface so that it extends. Then, the non-painted surface located near the boundary line is covered with the first tape. Next, the coating sheet is spread on a smooth surface such as a glass surface or a metal surface, and the second tape serving as an adhesive portion is extended along the edge portion of the coating sheet, and the edge portion and the smooth surface are formed. Glue so that it takes half each and. Then, the coating sheet is peeled off from the smooth surface.

Then, the coating sheet is held by hand and applied to the non-coated surface, and the second tape protruding from the edge of the coating sheet is placed at the position of the first tape already adhered to the non-coated surface. To match. When the second tape is adhered to the first tape in this state, the coating sheet is attached to the non-painting surface, and the non-painting surface located away from the boundary line is covered with the painting sheet. Be seen. If the boundary line between the surface to be painted and the unpainted surface extends on a straight line, etc., the second tape in the coating sheet may be directly bonded to the unpainted surface without adhering the first tape to the unpainted surface. Sometimes glued to.

The coating of the surface to be coated is carried out with the non-coated surface covered with the coating sheet. If the applied paint squeezes out from the surface to be painted to the non-painted surface,
Since the paint adheres to the coating sheet that covers the non-painted surface, adhesion of the paint to the non-painted surface is prevented. Therefore, by covering the non-painted surface with the coating sheet as described above, it is possible to reliably apply the paint only to the surface to be painted on the wall surface. In addition, the unpainted surface located near the boundary line
Since it is covered with the tape, the first tape can surely prevent the paint from adhering to the non-painted surface located near the boundary line which is difficult to cover with the coating sheet. .

[0006]

However, in the above-mentioned coating sheet, when the coating sheet is attached to the non-painting surface,
A smooth surface such as a glass surface is required, and the coating sheet must be once spread on the smooth surface and the second tape must be adhered to the edge of the coating sheet. Therefore, there is a problem that the work of attaching the coating sheet takes time and effort.

Further, when painting the wall surface in the factory,
Oil, dust, etc. are likely to adhere to a smooth surface such as a glass surface. Therefore, when spreading the coating sheet on the smooth surface and adhering the second tape, oil or dust on the smooth surface adheres to the second tape, and the adhesive strength of the second tape decreases. Therefore, in this case, before adhering the second tape to the edge of the coating sheet, it is necessary to wipe off the oil and dust adhering to the smooth surface with a cloth or the like. There was a problem that it took more time to work.

The present invention has been made in order to solve the above problems, and a first object thereof is to quickly and easily perform the work of attaching the coating sheet. The second purpose is to improve convenience during storage and transportation of the coating sheet.

A third object is to reduce the size of the coating sheet before use.

[0010]

In order to achieve the above object, in particular, an adhesive portion is provided on the edge portion of the sheet main body so as to extend along the edge portion.

According to a second aspect of the present invention, the sheet main body is wound into a scroll having an axis in a direction orthogonal to the extending direction of the adhesive portion, and the adhesive portion is not provided on the back surface side of the sheet main body. An adhesive surface for adhering to the coating surface is provided, and the adhesive surface of the sheet body can be peeled off when the sheet body is rewound in a portion where the adhesive surface of the sheet body abuts when the sheet body is in a rolled state. A release surface was provided.

According to the third aspect of the invention, the sheet body is wound in a state of being folded in a direction orthogonal to the extending direction of the adhesive portion. That is, according to the first aspect of the invention, the adhesive portion of the coating sheet is pressed against the non-coated surface side so as to extend along the boundary line between the surface to be coated and the non-coated surface. Then, the adhesive portion is adhered to the non-painted surface, and the painting sheet is attached so as to cover the non-painted surface.

According to the invention of claim 2, in addition to the operation of the invention of claim 1, the coating sheet is stored and carried in a rolled state. In this rolled state, the adhesive surface of the adhesive portion is adhered to the release surface provided on the sheet body. When using the coating sheet, peel off the adhesive part at the drawer end of the roll-shaped coating sheet from the release surface of the sheet body, and the edge of the drawn adhesive part on the opposite side of the sheet body is on the boundary line. The adhesive portion is adhered to the non-painted surface so as to be located at. In this state, the coating sheet in the form of a roll is pulled in a direction away from the pull-out end adhered to the non-coated surface. The adhesive portion pulled out by this pulling is extended along the boundary line and sequentially adhered to the non-painted surface.

According to the third aspect of the invention, in addition to the effect of the second aspect of the invention, the coating sheet is wound in a state where the sheet body is folded. Therefore, in the rolled state, the coating sheet has an axial direction. Is shortened.
