Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of collecting dust on the surface of an object on an outermost adhesive surface of the adhesive sheet while rotating the pressure-sensitive adhesive sheet wound on the object in contact with the object. Related to an adhesive roll.

[0002]

2. Description of the Related Art While a pressure-sensitive adhesive sheet wound in a roll shape is brought into contact with a floor surface and rotated, dust is collected on the outermost pressure-sensitive adhesive surface of the pressure-sensitive adhesive sheet and used. There is a pressure-sensitive adhesive roll in which an outermost pressure-sensitive adhesive surface is peeled off to expose an unused pressure-sensitive adhesive surface so that it can be used successively. As a prior art related to such an adhesive roll, for example, a roller tape of Registered Utility Model No. 3012451 is known.

[0003] This roller tape forms a groove extending to the core in a roll-shaped adhesive sheet wound around the core,
When peeling the used pressure-sensitive adhesive sheet 2, it is easy to find the end, but when long dust such as hair adheres to the pressure-sensitive adhesive surface so as to straddle the groove, the end is difficult to peel,
In addition, it was not hygienic because the hands touched the garbage.

On the other hand, Japanese Utility Model Laid-Open No. 7-12069 discloses that
Make a cut for cutting in the roll-shaped adhesive sheet wound around the core, and partially color the adhesive sheet along this cut to find the cut when peeling the used adhesive surface Although an adhesive roll that makes it easier is disclosed, when long dust such as hair adheres to the adhesive surface so as to straddle the cut as in the case of the roller tape, it is difficult for the end to peel off, It was not sanitary to touch.

In Japanese Utility Model Laid-Open Publication No. Hei 7-4001 and Japanese Patent Laid-Open Publication No. Hei 10-216066, the outermost adhesive surface of the adhesive sheet is cut by contacting the outer surface of the adhesive roll with a handle to which the adhesive roll is attached. There is disclosed a cleaning tool in which a cutter is mounted, a used adhesive surface is cut by the cutter, and the used adhesive surface is peeled off so that an unused adhesive surface can be exposed. Since these cleaning tools cut the used adhesive surface, they do not stick to long dust as in the above-mentioned prior art, so that they do not easily come off. However, there is a problem in hygiene. In addition, since the cutter is mounted on the handle, the size of the handle becomes large, and the weight is increased, making it difficult to use. Furthermore, there is a possibility that the cutter may be injured when the adhesive roll itself is removed, which is not preferable in terms of safety.

Accordingly, an object of the present invention is to provide an adhesive roll that can easily and hygienically remove a used adhesive surface.

The pressure-sensitive adhesive sheet 2 can be made of a usual material used for this type of pressure-sensitive adhesive roll without any particular limitation. The size and shape of the adhesive sheet 2 are not particularly limited.

In the present embodiment, the pressure-sensitive adhesive sheet 2 includes a core 4
It is wound around. The adhesive sheet 2 is provided with a slit 21 for cutting the adhesive sheet 2 at one place. The slit 21 is formed continuously over the entire width of the pressure-sensitive adhesive sheet 2 and has a depth extending from the outermost circumference to the innermost circumference of the pressure-sensitive adhesive sheet 2 so as to reach the core 4. ing. The width w2 of the slit 2 is
10 to 0.1 mm, in particular, 5 to 0.5 mm is sufficient from the viewpoint that can be cut smoothly.

The covering 3 is a covering portion (a portion covering the slit) 3 covering the slit 21 on the outermost adhesive surface 20a.
0 and a fixed end portion 31 that comes into contact with the side surface of the adhesive roll 20. The covering portion 30 is fixed to the adhesive surface 20 of the adhesive sheet 2 at both side edges 21 a of the slit 21. The distal end of the fixed end 31 is fixed with an adhesive 40a of the core 4 described later.

The width w3 of the covering portion 30 sufficiently covers the slit 21 so that the side edge 2
12-0.5m from the point that it can be fixed without peeling from 1a
m, in particular, 7 to 1 mm is sufficient.

Since the cover 3 rotates together with the roll-shaped pressure-sensitive adhesive sheet 2, the thinner the wall thickness, the better. In particular, the thickness of the covering portion 30 is preferably 0.02 to 0.5 mm, and is preferably 0.02 to 0.05 in terms of durability, ease of removing dirt attached to the slit, and the like. Is more preferred. Further, it is preferable that the covering portion and the fixed end have flexibility so as to be in close contact with the adhesive sheet 2.

The material of the cover 3 is not particularly limited.
It is preferable that the cover 30 and the fixed end 31 are formed of a synthetic resin material such as polyester or polypropylene from the viewpoints of adhesion to the pressure-sensitive adhesive sheet 2, durability, and easy removal of dirt attached to the slit. . The coating 3 is preferably colored. Further, it is preferable that the surface to be adhered to the pressure-sensitive adhesive sheet 2 has been subjected to an easy-peeling treatment such as silicone coating.

The winding core 4 is provided with fixing means 40 for fixing the fixed end 31 of the covering 3. Fixing means 40
In the present embodiment, is formed of an adhesive 40a disposed in a portion corresponding to the slit 21 in the side surface portion 41 of the core 4. The material of the adhesive 40a is not particularly limited as long as the adhesive force is not reduced by repeated attachment and detachment of the fixed end portion 31. For example, styrene-isoprene-styrene (SIS) hot melt, acrylic adhesive A material such as an agent can be used.

The adhesive roll 1 can be used, for example, by attaching it to a commercially available handle (not shown) having a rotatable attachment roller. Specifically, the mounting roller is inserted into the core 4 of the adhesive roll 1 from the side where the fixed end portion 31 of the cover 3 is not provided, and the outermost adhesive surface 20a of the adhesive roll 1 is inserted.
Is brought into contact with an object such as a floor, and the adhesive roll 1 is rotated so that dust on the surface of the object adheres to the adhesive surface 20a and is collected.

When the dust is sufficiently collected on the adhesive surface 20a, the cover 3 is removed from the fixed end 30 side, and the adhesive surface 20a is cut off at the slit 21 to be discarded and an unused adhesive surface is removed. Expose. At this time, since the place where the cover 3 is fixed is the place where the slit 21 is present, the end of the adhesive surface 20a can be quickly found. Further, even if long dust such as hair adheres so as to straddle the slit 21, the dust is also peeled off when the cover 3 is peeled off, so that it does not become difficult to peel off when the adhesive surface 21a is peeled off. Further, since the covering body 3 is fixed on both side edges of the slit 21 and no dust adheres to the both side edges, the hands are hardly stained when the adhesive surface 20a is picked and peeled off. .

After exposing the new adhesive surface, the cover 3 is fixed again to both sides 21a of the slit 21 and the adhesive 40a so as to cover the slit 21.
