DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adhesive tape roll for dust removal wound with an adhesive surface facing outward, and more particularly to an adhesive tape roll having no restriction on the rolling direction.

[0002]

2. Description of the Related Art For example, dust such as hair and dust entangled in a carpet (carpet) is difficult to remove even if it is suctioned using a vacuum cleaner. It can be troublesome to use.

In such a case, an adhesive tape roll is convenient. That is, the adhesive tape roll is a roll formed by winding an adhesive tape having an adhesive surface on one side with the adhesive surface side as an outside, and merely rolling on a surface to be cleaned such as a floor, the dust action due to the adhesive action. Can be easily taken. Further, since the configuration is simple and the weight is light, it is easy to use.

However, it is undeniable that the adhesive strength becomes weak in inverse proportion to the amount of dust attached. If the adhesive strength falls, the dirty adhesive tape is peeled off by one roll and a new lower adhesive tape is newly formed. The surface needs to be exposed. To facilitate this peeling operation, the adhesive tape roll is provided with, for example, perforated cuts.

[0005]

Therefore, the dirty adhesive tape can be relatively easily peeled off along the cut, but the conventional cut has the following problems.

Referring to FIG. 5, in many cases, the pressure-sensitive adhesive tape 20 is wound in a spiral shape and the pressure-sensitive adhesive tape roll 1 is wound.
From 0, a cut is made in the radial direction at once by a cutter (not shown).

According to this, since the adhesive tape 20 for exactly one round is peeled off, the rolling direction of the adhesive tape roll 10 is restricted. That is, although it depends on the adhesive strength of the adhesive surface, when the adhesive tape roll 10 is rolled in the direction opposite to the winding direction (the direction in which the adhesive tape is unwound), as shown in FIG. As a result, the adhesive tape 20 sticks to the floor surface G in a belt shape.

Such a sticking phenomenon does not occur if the adhesive tape roll 10 is rolled in the winding direction. Therefore,
For example, an arrow mark M indicating the direction of rolling on the adhesive tape 20
Is printed, but it is not preferable on the maker side because the printing cost is extra. Further, even on the consumer side, there is a case where the user inadvertently rolls in the opposite direction despite the presence of the arrow mark M.

[0009]

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and an object of the present invention is to provide a cleaning method for a surface to be cleaned even if the adhesive tape is rolled in a direction opposite to the winding direction. An object of the present invention is to provide an adhesive tape roll in which an adhesive tape is prevented from sticking.

[0010] To achieve the above object, the present invention provides
An adhesive tape in which one surface of a substrate made of a band-shaped sheet having a predetermined width is an adhesive surface is wound so that the adhesive surface side is on the outside, and the adhesive tape has a cut crossing its circumferential direction. Are formed at predetermined intervals, and the adhesive tape of the outermost layer is peeled off along the cuts, so that the adhesive tape of the next layer is sequentially exposed, and the gap between the adjacent cuts has a circumferential length. Less than 360 °, and the adhesive surface of the adhesive tape of the next layer is included in a part of the adhesive surface exposed on the outermost surface.

According to the present invention, dust adheres to the end of the cut of the next layer of the adhesive tape, that is, the adhesive tape to be used (exposed) next, and the adhesive force of the portion is weakened. . Therefore, when the adhesive tape of the outermost layer is peeled off and the adhesive tape of the next layer is used, even if it is rolled in the direction opposite to the winding direction, the cut end of the next layer is less likely to adhere to the surface to be cleaned. The cut end is not turned up from the surface to be cleaned, and the adhesive tape does not stick to the surface to be cleaned.

In the present invention, the base material of the pressure-sensitive adhesive tape may be either a paper sheet or a foamed resin sheet, and is not particularly limited. Paper sheets are mainly suitable for carpets, and foamed resin sheets are mainly suitable for flooring. And the adhesive strength is generally set stronger for the carpet than for the flooring, but the adhesive surface of the adhesive tape of the next layer included in a part of the adhesive surface exposed on the outermost surface The width may be determined by an empirical rule according to the strength of the adhesive force.

In the present invention, the structure and shape of the cut are not particularly limited. That is, the cut may be a perforated shape or a thin shape. In short, any fragile portion that is easily cut may be used.

The direction of the cut may be either a direction orthogonal to the circumferential direction of the adhesive tape or a direction obliquely intersecting the circumferential direction of the adhesive tape. Further, the cut may be any one of a linear shape, a wavy shape, and a non-linear shape such as a saw blade shape. At least one end of the adhesive tape,
A non-viscous surface having no tackiness may be formed.

[0015]

Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of an adhesive tape roll according to one embodiment of the present invention.

This pressure-sensitive adhesive tape roll 1 is formed by bonding a pressure-sensitive adhesive tape 2 having a pressure-sensitive adhesive surface 22 on one surface of a base material 21 made of a band-shaped sheet of a predetermined width to a hollow pipe 4 so that the pressure-sensitive adhesive surface 22 is located outside. It is wound in a spiral.

In this embodiment, a polyethylene sheet (foam type) is used as the base material 21, but a paper sheet or a resin sheet may be used instead.
The adhesive surface 22 is made of a predetermined adhesive material, but the adhesive material does not necessarily need to be applied to the entire surface of one surface of the base material 21, but may be applied in a streak shape, an island shape, a grid shape, or the like. May be. In some cases, a foamed adhesive may be used.

The adhesive tape 2 is provided with a cut 3 from one end to the other end in the width direction. This cut 3
Are formed on the adhesive tape 2 at a predetermined interval. In the present invention, the interval between adjacent cuts 3 (the length of one adhesive tape 2 cut from the cut 3) is 360 ° in circumferential length. , And there is an interval Δd between adjacent cuts 3a and 3b (3b and 3c,..., 3n-1 and 3n).

That is, a large number of adhesive tape portions 2a, 2
, 2n are continuously connected to each other through a gap 3, and as shown in FIG.
When the second adhesive tape portion 2b is to be used by exposing the second adhesive tape portion 2b, the adhesive surface of the second adhesive tape portion 2b is attached to the newly exposed outermost adhesive surface.
2 and a part of the adhesive surface 22 of the third adhesive tape portion 2c (the surface of the above-mentioned interval Δd).

Similarly, when the second adhesive tape portion 2b becomes dirty and cut off from the cut 3b, the entire adhesive surface 22 of the third adhesive tape portion 2c and the adhesive surface 2 of the next fourth adhesive tape portion 2d are removed.
Part of the surface of No. 2 is exposed as the outermost adhesive surface. In this embodiment, the cut 3 is shown as a perforation, but the cut 3 may be a weak portion formed in a thin shape such as a V-shape.

The pressure-sensitive adhesive tape roll 1 can be obtained by winding the pressure-sensitive adhesive tape from a raw pressure-sensitive adhesive tape roll (mother roll) (not shown) into individual sizes through a cut forming portion having a Thomson blade or the like. For example, by selecting a predetermined gear ratio between the adhesive tape roll 1 side and the material roll side, as illustrated in FIG.
The cut 3 can be formed in a step shape for each circumference.

As described with reference to FIG. 1, in a state where the first adhesive tape portion 2a is peeled off and cut off from the cut 3a, the adhesive tape roll 1 is rotatably attached to a support (not shown), and the surface to be cleaned, for example, the floor Fig. 2
As shown in the figure, dust such as shavings 6
Adheres.

In this case, on the outer surface of the adhesive tape roll 1, in addition to the entire surface of the adhesive surface 22 of the second adhesive tape portion 2b,
A part of the adhesive surface 22 of the third adhesive tape portion 2c as the next layer,
That is, since the adhesive surface 221 of the portion that enters the inside of the third adhesive tape portion 2c from the next cut 3b by the above-described interval Δd is exposed, the dust 6 also adheres to the adhesive surface 221.

When the adhesive strength is weakened due to the adhesion of the dust 6, the second adhesive tape portion 2b is peeled off and cut off from the cut 3b, and the adhesive surface 22 of the next third adhesive tape portion 2c is used. As shown in FIG. 3, dust 6 has already adhered to the adhesive surface 221 at the end of the third adhesive tape portion 2c on the side of the cut 3b, and the adhesive force has been weakened.

Therefore, as shown in FIG.
Even when the adhesive tape roll 1 is rolled in the direction A opposite to the winding direction, the edge of the cut 3b is not wound from the floor surface G side, and the third adhesive tape portion 2c is formed in a band shape on the floor surface G. No sticking.

In addition, while making the cut 3 easy to see,
To make it easier to pick the gap 3 with your finger, use an adhesive tape 2
Is preferably a non-adhesive surface having no tackiness. Further, the application range of the adhesive tape roll 1 is not limited to carpets and flooring floors, but can be applied to, for example, desk-side dust removal and dust removal of futons and clothes.

[0027]

As described above, according to the present invention,
An adhesive tape in which one surface of a substrate made of a band-shaped sheet having a predetermined width is an adhesive surface is wound so that the adhesive surface side is on the outside, and the adhesive tape has a cut crossing its circumferential direction. Are formed at predetermined intervals, and the adhesive tape of the outermost layer is peeled off along the cuts, so that the adhesive tape of the next layer is sequentially exposed, and the gap between the adjacent cuts has a circumferential length. Less than 360 °, and a part of the adhesive surface exposed on the outermost surface includes the adhesive surface of the next layer of the adhesive tape, thereby being opposite to the winding direction of the adhesive tape. Even if it rolls in the direction, the adhesive tape can be prevented from sticking to the surface to be cleaned.

Therefore, the manufacturer does not need to print a guide mark indicating the direction of rolling on the adhesive tape, and the consumer (user) can use the guide mark without having to worry about the rolling direction. it can.
