Abstract

PROBLEM TO BE SOLVED: To solve such a problem that in a wound up roll with a cut line from outside, the cut is widened and raised, dust enters the cut line part, the raised part inhibits smooth rotation, and dust cannot be cleanly removed. SOLUTION: A tape 1 with an adhesive layer 6 on one side is provided with a plurality of discontinuous cut lines 4 extending in the width direction spaced apart. The discontinuous cut lines 4 are formed on the tape 1 so as to be arranged at substantially the same position and have respective intervals between the adjacent discontinuous cut lines 4 gradually widened when the adhesive layer 6 is wound around a core 3 as the outer surface. The tape 1 provided with the discontinuous cut lines 4 is wound to form an adhesive dust removing roll 7. A cut portion 41 of the discontinuous cut line 4 is made shorter and an uncut portion 42 between the cut portions is made further shorter. Therefore, the cut portion 41 of the adhesive dust removing roll 7 does not widen and rise, and a smooth rotation of the roll removes the dust cleanly.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to improvement of a dust removal roll using an adhesive.

[0002]

2. Description of the Related Art A sticky dust removing roll is wound around a winding core so that the adhesive layer is on the outer surface, and the roll is placed on a dirty carpet, floor or the like. Rolling is performed to attach dust to the adhesive layer for cleaning. When a large amount of dust adheres to the pressure-sensitive adhesive layer and the adhesiveness deteriorates and cleaning becomes impossible, the dirty part is peeled off to expose a new pressure-sensitive adhesive layer. A tear line is provided on the tape of the roll for peeling and removing.

Conventionally, the cut line 21 is a tape having an adhesive layer 22 formed on one surface thereof, and the tape 2 has the adhesive layer as the outer surface.
3 and the knife is inserted into the wound roll 24 from the outside to the core so that the cutoff line 21 for each turn is provided at once. Therefore, the cutline portion 25 is shortened and the cutline portion is cut. It is difficult to form a short connecting portion 26 between the two.

Since the cut line portion 25 has a length of at least about 15 mm or more, the cut line portion of the cut line naturally expands and rises outside the roll 24 to remove dust. When the roll was rotated, the swelling part caused it to roll with the ruggedness and the rotation became unsmooth, and smooth dust removal could not be done, and dust got into the expanded cutting line part and could not be removed (Fig. 6 to 8).

Further, in order to make it easier to peel off the tape soiled with dust, the cut line 2 is formed in the same manner as described above.
Although there is one in which the cut line portion 25 of 1 is formed long (Fig. 9), the longer the cut line portion 25 becomes, the larger the cut line portion becomes to be expanded, and the cut line portion 25 becomes larger during the dust removal work. Since dust enters deep inside the parts and accumulates one after another, there is a phenomenon that even if the outer surface part of the roll on which dust is adhered is peeled off, a clean roll cannot be obtained.

There is also one in which the cut line portion 25 of the cut line is staggered so that the entire cut line is substantially inclined (FIG. 10), which is easy to separate from the cut line. However, the cutting line part has expanded,
I couldn't avoid the state of excitement.

SUMMARY OF THE INVENTION The present invention is directed to a dirty roller.
The cutting line for removing the tape of the roll does not spread and rise, the roll keeps the cylindrical shape and the smooth rotation facilitates the cleaning, and the dirty tape is also reliably removed. It is something that tries to be able to.

[0008]

According to the present invention, a tape having an adhesive layer on one surface thereof is provided with a plurality of discontinuous cut lines extending in the width direction at intervals, and the discontinuous cut lines form the adhesive layer. When the tape is wound around the winding core so as to be the outer surface, the distance between adjacent discontinuous cut lines is gradually increased so that they are located at substantially the same position, and the tape provided with such discontinuous cut lines is wound. It was turned to make an adhesive dust removal roll.

Further, the cut line portion of the discontinuous cut line is formed to be short, and the connecting portion located between the cut line portions is formed to be further short. Each of the discontinuity cutting lines is provided so that the tape which extends from the discontinuity cutting line immediately before it and is wound is located at a position slightly beyond the discontinuity cutting line immediately before that. There is.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION The base material 2 of the tape 1 can be made of paper, plastic film, cloth or other materials, but usually paper is often used because of its economical efficiency. The width of the base material 2 is an appropriate width according to the application,
Usually, it is good to set the width to about 9 to 30 cm.

The pressure-sensitive adhesive layer 6 is formed on one surface of the base material 2 and a light peeling treatment is performed on the other surface, if necessary, depending on the type of the base material or the pressure-sensitive adhesive. As the pressure-sensitive adhesive for the pressure-sensitive adhesive layer, a rubber-based, acrylic-based or other pressure-sensitive adhesive can be used. Generally, a hot melt type adhesive is often used.

The core 2 is attached to the base material 2 on which the adhesive layer 6 is formed.
A discontinuous cut line 4 extending in the width direction of the tape is provided so that the tape can be cut substantially every single winding when wound. Since the diameter of the base material 2 increases as it is wound around the winding core 3, the base material 2 is sequentially formed so that the interval between the adjacent discontinuous cut lines becomes gradually longer.

The discontinuous cut line 4 is formed by the cut line portion 41 and the connecting portion 42, and the length of the cut line portion can be arbitrary, but it is not more than about 15 mm, preferably about 10 mm. It is good to set it below the level. In particular, the cutting line portion 41 can be made as short as about 2 mm and the connecting portion 42 can be made as short as about 1 mm. If the length of the cutting line portion is shortened, the above-mentioned widening of the cutting line portion is further difficult to occur. 1 to 3, a convex portion 43 is formed in the central portion of the discontinuous cut line 4, and the convex portion 43 is folded back when used as described later.

A certain discontinuous cut line 4 provided on the tape is
When it is wound, it should be almost at the same position as the previous discontinuous cut line. That is, a certain discontinuity cutting line may overlap with the preceding discontinuity cutting line (Fig. 3), or it may be positioned at a position slightly displaced in the vicinity of the preceding discontinuity cutting line without overlapping. Good. In this case, if it is located at a slightly displaced position, the cut line portion will not expand and the roll will be less likely to rise, and the whole can be made into a round cylindrical shape and can be maintained.

Particularly preferably, the certain discontinuous cut line is
If the tape is placed so as to be slightly beyond the previous discontinuity cut line, dust will become attached to the entire new outer surface when the dust-contaminated tape described later is cut off by the discontinuity cut line. The adhesive layer which is not present is exposed for convenient use (FIGS. 4 and 5).

The tape 1 thus formed with the discontinuous cut line 4
Is wound around the core 3 so that the pressure-sensitive adhesive layer 6 is on the outer surface to form a roll 7. Although the number of windings is arbitrary, it is usually about 50 to 100 times, that is, the discontinuous cut line is about 50 to 10 times.
In many cases, the number of wound pieces is about 0. Also,
In some cases, the adhesive layer 6 may be formed after the discontinuous cut lines 4 are provided on the base material 2. A release paper (not shown) may be wound on the outermost side of the roll 7 to protect the pressure-sensitive adhesive layer 6.

When this adhesive dust removal roll 7 is used, it is rotatably attached to the operating handle 8 and the adhesive layer 6 is used.
The pressure-sensitive adhesive layer is exposed when the release paper covering the is peeled off. When the roll 7 is rolled on a dirty carpet or the like, the cut line portion 41 of the discontinuous cut line 4 does not spread and rise outward, so the roll 7 is smoothed. -It can be rotated to remove dust by attaching it evenly and cleanly.

When the dust is removed by the roll, the dust adheres to the entire surface of the pressure-sensitive adhesive layer 6 and the end portion of the roll at the end of winding cannot be seen. Therefore, in the case shown in FIGS.
Before the cleaning is started, if the convex portion 43 of the discontinuous cut line 4 is folded back to the outside and the adhesive layers are stuck together (FIG. 1), dust will not adhere to the folded convex portion 43. It serves as a mark when removing the outermost part of the dirty roll, and it is convenient to pinch this part to rewind the roll.

Further, as shown in FIGS. 4 and 5, when the end portion 9 at the end of winding is folded back slightly outward along the tape width direction as described above, this folded line portion 10 is cut next. If the discontinuous cut lines are formed in advance so as to be positioned almost above the discontinuous cut line 4 at intervals that allow for the length of the sheet to be folded back, a new adhesive layer will be formed when the dirty tape is cut off. It is convenient because it appears all around.

When dust cannot adhere to the adhesive layer on the outer surface and cleaning cannot be performed, the folded convex portion 43 and the end portion 9 at the end of winding of the roll are picked to rewind one roll, When pulled so that it acts on the discontinuous cut line, it is cut along the discontinuous cut line, and the separated sheet can be discarded by folding with the adhesive layer side with dust inside. . Then, since a new, uncontaminated pressure-sensitive adhesive layer is exposed on the outer surface of the roll, similarly to the above, after slightly folding back the convex portion 43 or the cut-off end portion 9 , Roll can be rolled and dust can be attached to clean it.

[0021]

As described above, according to the present invention, the pressure-sensitive adhesive layer formed on one surface of the tape is formed so that the distance between the discontinuous cut lines extending in the width direction of the tape is gradually increased. Since it is wound like this, the wound roll does not become a round tubular shape and the cut line part of the discontinuous cut line does not spread, and since a short cut line part can be used as the discontinuous cut line, A clean cylindrical roll can be obtained. In addition, since the discontinuous cut line is formed on the tape and then wound around the roll, the discontinuous cut line can be easily formed, and even if the cut line portion is short, it is possible to freely form a cut line.
