Description

[Detailed Description of the Invention] This invention relates to a corner tape, and more particularly to a corner tape attached to an inner corner of a rising part of a floor and a wall in a room, or an inner corner of a wall where they intersect. Conventionally, rising parts of indoor floors and walls,
Alternatively, it is often difficult for cleaning tools to reach the inner corners of intersecting walls, making it difficult to completely remove dust.

In order to overcome these difficulties, it is sometimes done to attach square timbers with concave curved surfaces or sloped cross sections to these inner corners, but this is difficult and expensive to install, making it difficult to implement. There was a drawback that it was not easy.

In view of the above, this invention was made for the purpose of providing a corner tape that can easily correct and deform the shape of the corner part where dust has accumulated. The present invention is characterized in that both side bands are made soft and are coextruded to form a tape-like base material, and an adhesive layer is provided on one side of the both side band portions.

Next, this invention will be explained using examples.

FIG. 1 shows a sectional view of an embodiment of this invention.

The corner tape A of this invention is the center band 1A.
is hard, e.g. hard polyvinyl chloride, both side bands 1
B, 1B are soft, for example, soft polyvinyl chloride, and an adhesive layer 2, 2 is provided on one side of both side band parts 1B, 1B of the tape-shaped base material 1, which are extruded at the same time. There is.

It is desirable that the thickness of the side band portions 1B, 1B be formed to be thinner than the thickness of the center band portion 1A by the thickness of the adhesive layers 2, 2, as shown in the figure. In addition, 3 and 3 in the figure are release papers temporarily attached on the adhesive layers 2 and 2.

In the above-mentioned embodiment, a structure in which the hard and soft parts are different in the width direction of the tape-shaped base material 1 was shown, but a structure in which the hard and soft parts are different in the thickness direction as shown in FIG. 2 is also possible. That is, FIG. 2 shows a sectional view of another embodiment, in which soft members forming both side bands 1B are made wider than the central band 1A and extruded at the same time on the hard part forming the central band 1A. The adhesive layer 2, 2 is provided on one side of both side bands 1B, 1B.

To use the corner tape A of this invention, first peel off the release paper 3, 3, and paste it on the intersecting floor F and wall W, respectively, as shown in Figure 3.
By bending the rigid central band 1A, the inner corner portion P is covered and hidden.

Since this invention is constructed as described above, it is possible to easily form a curved corner of the interior of the room where dust tends to accumulate, making it extremely easy to remove dust. Moreover, since the curved central band is hard, it has excellent strength and will not be damaged or deformed by a slight impact. The corner tape of this invention can be particularly effective when used in a fully air-conditioned room or the like where dust must be removed.
