Abstract

[Problem] When using a dust-removing roll-shaped adhesive tape, since the roll is rolled while being pressed, the surface-layer adhesive tape and the next-layer adhesive tape are firmly adhered to each other. It is intended to solve the drawbacks that it is difficult to smudge and that it tears in an unexpected direction without peeling along the cut. A cut 1 for guiding peeling of a surface adhesive tape 4 saturated with dust is inclined at 25 to 35 degrees with respect to the axial direction of the roll, and has a length that divides the roll into three equal parts, and the ends of the top and bottom cuts overlap each other. arranged parallel to each other. In addition, upper and lower cuts A and B are made at the end of the cut so that the adhesive tape does not tear in an unexpected direction, and the cuts are not connected so that the adhesive tape does not shift or come off during use. Further, the upper cut portion 1 is bent to form a peeling grip portion 6 so that the tape to be peeled off can be easily gripped. [Selection drawing] Fig. 1

Description

TECHNICAL FIELD The present invention relates to a dust-removing roll-shaped adhesive tape that is used to remove dust using its adhesiveness.

background technology

Dust adheres to the adhesive surface of the dust-removing roll-shaped adhesive tape, and when its performance decreases, a new adhesive tape is exposed. Can continue to use. In order to facilitate this stripping operation, it is common to make perforations or cuts along the axis of the roll, or to provide cuts at both ends of the roll.

Problems that ideas can solve

The problem to be solved by the present invention is that when using a dust-removing roll-shaped adhesive tape, the roll is rolled while being pressed, so that the surface layer adhesive tape 4 and the next layer adhesive tape 5 are firmly adhered, so that dust does not adhere. When one week's worth of the surface layer adhesive tape 4 whose ability has deteriorated is peeled off, it is difficult to recognize the cut to be peeled off, it is difficult to pick up one piece of the tape, and it is torn in an unexpected direction when peeled off along the cut line. It tries to solve some shortcomings.

Means to solve problems

The present invention has been made to solve the above problems. In the dust-removing roll-shaped adhesive tape, in order to make it easier to peel off the surface layer adhesive tape 4 that is saturated with dust, the cut that guides the peeling is provided. , The upper cut 1, the middle cut 2, and the lower cut, which are inclined at 25 to 35 degrees with respect to the roll axis direction, the length is equal to 3 rolls, each is parallel at intervals of 5 mm to 6 mm, and the ends can overlap by 4 mm to 5 mm. 3, and the ends of the upper cut 1 and the lower cut 3 on both ends of the roll are provided with an upward cut A at a distance of 3 mm to 4 mm from the roll end, and the end of the upper cut 1 and the lower cut 3 overlapping the middle cut 2 A downward cut B is provided at the ends of the intermediate cuts 2 overlapping with the bottom cuts 2 mm to 3 mm apart from the underlined cuts. In addition, the problem is solved by making the cut deep enough to reach the core of the roll.

When the surface layer adhesive tape 4 before use is peeled off when the dust is saturated, the surface layer adhesive tape 4 is separated from the surface layer adhesive tape 4 when the front layer adhesive tape is peeled off, so that only one sheet of the surface layer adhesive tape 4 can be easily picked up. The problem is solved by providing a peeling knob 6 that bends and adheres the inclined upper cut 1 line to the front side parallel to the roll axis direction so that the upper tip of the roll protrudes from the roll end.

Effect of idea

According to the dust-removing roll-shaped pressure-sensitive adhesive tape of the present invention, since the cuts that guide the peeling are made oblique to the roll axis, the force is directed in the peeling direction, making it easier to peel along the cut lines.

The downward cut B at the ends of the upper cut 1 and the middle cut 2 ensures tearing toward the lower cut. In addition, the upward cut A at the ends of the upper cut 1 and the lower cut 3 facilitates tearing toward the roll end.

Since the respective cuts are not connected and are not cut to the end of the roll, it is possible to prevent the adhesive tape from slipping or peeling off when the dust-removing roll-shaped adhesive tape is used. In addition, when peeling off the surface layer adhesive tape 4 saturated with dust, one portion of the upper cut portion of the next layer adhesive tape 5 connected thereto can be lifted, so that it is easy to bend into the peeling knob 6 and the adhesive to be peeled off. It becomes easy to pick up one piece of tape.

Specific embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing a dust-removing roll-shaped adhesive tape according to one embodiment of the present invention. As shown in this figure, in the dust-removing roll-shaped adhesive tape of this embodiment, in order to facilitate the stripping of one week's worth of the surface-layer adhesive tape 4 to which dust has adhered in a saturated state, the guiding cuts are 25 in the roll axis direction. 35 degrees, the length is equal to 3 rolls, each is parallel at intervals of 5 mm to 6 mm, and the ends are overlapped by 4 mm to 5 mm. The ends of the upper cut 1 and the lower cut 3 on the side are provided with an upward cut A at a distance of 3 mm to 4 mm from the roll end, and the end of the upper cut 1 that overlaps with the middle cut 2 and the end of the middle cut 2 that overlaps with the lower cut 3. In each part, a downward cut B is provided 2 mm to 3 mm away from the underlined cut. In addition, by making cuts deep enough to reach the core of the roll, this dust-removing roll-shaped adhesive tape is easy to use all the way through.

When the surface layer adhesive tape 4 before use is peeled off when the dust is saturated, the surface layer adhesive tape 4 is separated from the surface layer adhesive tape 4 when the front layer adhesive tape is peeled off, so that only one sheet of the surface layer adhesive tape 4 can be easily picked up. By providing a peeling knob 6 that folds and adheres the inclined upper cut 1 line to the front side parallel to the roll axis direction so that the upper tip part of the dust removal roll sticks out from the roll end Easier to use.
