Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust-removing pressure-sensitive adhesive tape wound with the pressure-sensitive adhesive surface facing outward.

[0002]

2. Description of the Related Art A dust-removing pressure-sensitive adhesive tape wound with the adhesive surface of the adhesive tape facing outward is used when the adhesive force is lost due to the adhesion of dust. By peeling it off, a new adhesive surface can be exposed for repeated use.

However, when peeling off the part of the adhesive tape on which dust is adhered, the dust adhered part may remain or may be peeled off to an unnecessarily long length, making it difficult to peel off just one revolution. There are cases. In particular, the adhesive tape may not be peeled off neatly at the beginning of peeling, and the adhesive tape may be torn in the winding direction before the entire width of the adhesive tape is peeled off.

In order to eliminate such inconvenience, there is one in which a perforation for cutting is provided on the surface of the adhesive tape. The perforations include those provided in the axial direction of the cylindrical adhesive tape, those provided obliquely to the axial direction, and the like, and the perforations are cut off along the perforations to facilitate peeling.

[0005]

However, even an adhesive tape provided with perforations for cutting may be torn in the winding direction of the tape from a place where there is no boundary between the perforations. Therefore, there is an inconvenience of having to peel it off carefully.

In order to solve this problem, it is possible to equip the cleaning tool with a cutter or the like for cutting the adhesive tape.
Although effective for cutting off the adhesive tape that has been peeled off, it is not considered that the entire widthwise direction can be peeled off neatly when the adhesive tape starts to be peeled off. Also, the provision of a cutter or the like is not suitable for safety, and the advantages of a lightweight and simple cleaning tool are impaired.

An object of the present invention is to provide a dust-removing pressure-sensitive adhesive tape capable of easily peeling off one round of the pressure-sensitive adhesive tape to which dust has adhered.

[0008]

In order to solve the above problems, according to the present invention, an adhesive tape having an adhesive surface on one side is wound around the peripheral surface of a hollow cylinder as a core with the adhesive surface facing outside. In the dust-removing adhesive tape, a cut extending from the outer surface to the inner surface is formed in the winding layer of the adhesive tape, the cut extending from one cylinder end of the winding layer to the other cylinder end, and both cylinder ends. The positions of the cuts are shifted in the circumferential direction of the wound layer and are formed.

Since the cut is provided in this way, the adhesive tape can be peeled off in the widthwise direction along the cut,
And one round can be removed along the break.

That is, since the peeling force acts in the unwinding direction of the adhesive tape, when a cut is provided in the axial direction of the cylinder, for example, the direction of the peeling force and the direction of the cut are close to the right angle, and in the middle of the cut. Although it is easy to tear, since the break of the present invention is closer to the direction of peeling force, it is hard to tear in the middle of the break and can be peeled off cleanly along the break. Further, even if dust adheres to the adhesive surface, the cuts also appear in the layer-thickness-wound thickness portion, so that the portion where the peeling has started can be easily recognized.

Further, when peeled off from one cylinder end along a slit, two or more adhesive tapes may be peeled off on the other cylinder end side. Therefore, in order to prevent this, the wound layer of the adhesive tape The cut extending from the outer surface to the inner surface of the winding layer is formed by shifting from one cylinder end of the winding layer in the peeling direction of the adhesive tape, and the continuous non-adhesive band is formed on the other cylinder end side of the winding layer. Is preferably formed in the circumferential direction of the side edge.

In addition, the cut extending from the outer surface to the inner surface of the winding layer of the adhesive tape is such that the cut provided in the adhesive tape inside the winding layer is shifted to the rewinding side of the adhesive tape from the cut of the outside adhesive tape. It is preferably formed. Since the cut is made in this manner, when the peeling is started, the fingertip is caught only on the outermost tape and the adhesive tape on the lower layer is hard to touch, so that only one sheet can be easily peeled off.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of an embodiment of an adhesive tape for dust removal according to the present invention, and FIG. 2 is a perspective view of another embodiment.

As shown in FIG. 1, the dust-removing adhesive tape 1 comprises a cylinder 3 as a core, and an adhesive tape 5 wound on the peripheral surface of the cylinder 3 in layers with the adhesive surface facing outward. ing. The adhesive tape 5 is formed with a cut 7 extending from the outermost layer of the adhesive tape, which is the outer surface, to the innermost layer of the adhesive tape, which is directly wound around the core cylinder 3. The cut 7a that appears on the surface that is the peripheral surface of the layered wound adhesive tape 5 extends from one cylinder end of the winding layer to the other cylinder end, and the position of the cut 7a at both cylinder ends is The winding layers are formed at different positions in the circumferential direction. That is, the cut 7a appearing on the surface of the adhesive tape is provided between one cylinder end and the other cylinder end, and is formed obliquely with respect to the axial direction of the cylinder 3. Further, the cut 7b appearing on the thickness side of the pressure-sensitive adhesive tape 5 wound in layers is formed from the outermost layer which is the outer surface to the innermost layer in the radial direction.

Next, the operation of the dust-removing adhesive tape 1 thus constructed will be described with reference to FIG. The dust-removing adhesive tape 1 is used by being attached to a cleaning tool (not shown) of a mechanism including a rod-shaped jig that fits in a cylindrical opening that is the core of the adhesive tape 1. And the adhesive tape for dust removal 1
However, by rolling the floor surface or the like and contacting the adhesive surface with the floor surface or the like, dust on the floor surface or the like is adhered to the adhesive surface and removed. If this cleaning tool is used repeatedly, the adhesive tape surface will be covered with dust and the adhesive strength will decrease, so by peeling off the adhesive tape for just one lap of the outer surface, a new adhesive tape is exposed for repeated use. It will be. In this peeling, the peeling is started from the end side 9 of the adhesive tape on the side where the angle formed by the cut 7a and the side in the winding direction of the adhesive tape is an acute angle. Since the direction of the peeling force is applied to the rewinding direction of the adhesive tape, for example, when a cut is provided in the axial direction of the cylinder 5, the angle between the direction of the cut and the direction of the peeling force is close to a right angle, The adhesive tape easily tears in the width direction. Since the direction of the cut 7a in this embodiment is closer to the direction of the peeling force,
Hard to tear on the way and easy to peel off along the break.

In this way, the adhesive tape is cut into the cylinder 5
Since it is placed obliquely to the axis direction of, the adhesive tape can be peeled off just one round along the cut. Further, even if dust adheres to the adhesive surface, a cut appearing in the thickness portion of the adhesive tape can be seen from the axial direction, so that the portion where the peeling has started can be easily found.

Next, another embodiment of the adhesive tape for dust removal of the present invention will be described with reference to FIG. FIG. 2 is a perspective view of another embodiment, and the same components as those in the above-described embodiment use the same reference numerals. The difference from the above-described embodiment is that the cut 7c extending from the outer surface to the inner surface of the wound layer of the pressure-sensitive adhesive tape 5 wound in layers is such that the cut provided on the pressure-sensitive adhesive tape inside the wound layer is the outside adhesive. That is, it is formed so as to be shifted from the break of the tape toward the rewinding side of the adhesive tape. That is, the cut 7c appearing on the thickness side of the winding layer
Is a point provided obliquely with respect to the thickness direction from the outer surface toward the rewinding side of the adhesive tape.

Since the feature is added to the direction of the cut that extends from the outer surface to the inner surface in this way, when the used adhesive tape is peeled off, the fingertip is caught only on the outermost tape and it is difficult to touch the adhesive tape on the lower layer. It becomes possible to easily peel off only one sheet.

Next, still another embodiment of the dust collecting adhesive tape of the present invention will be described with reference to FIG. FIG. 3 is a perspective view of still another embodiment, and the same components as those in the above-described embodiment use the same reference numerals. The difference from the above-described embodiment is the cut reaching the inner surface from the outer surface of the winding layer of the adhesive tape, and the cut surface 7a appearing on the peripheral surface of the adhesive tape 5, that is, the surface is a cylinder end of one of the winding layers. It is formed by shifting the adhesive tape in the direction of peeling the adhesive tape, and a continuous non-adhesive band is formed in the side end circumferential direction on the other cylinder end side of the winding layer. When peeling the adhesive tape from one cylinder end in the direction of peeling the adhesive tape and peeling it along the cut 7a obliquely provided, two or more sheets may be peeled off at the other cylinder end, so there is no break to prevent this. That is, the non-adhesive band is provided on the other cylinder end side. The adhesive applied to the adhesive tape may not be uniform, and when the cut line is provided from one end to the other end of the tube end, when peeled from one end along the cut line,
It may peel off more than one sheet. Therefore, a continuous non-adhesive band on the other end, that is, a portion not coated with the adhesive is provided in the side end circumferential direction. The width of the non-adhesive band is preferably about several millimeters, for example.

Further, it is preferable to provide a non-adhesive band also on the end portion side of the tubular end portion of the adhesive tape, which is the portion where the peeling is started. This is because it becomes easier to start peeling.

The adhesive tape for dust removal according to the present invention is
It is not limited to removing dust from the floor, but can also be used to remove dust adhering to fibers such as clothes.

[0022]

As described above, according to the present invention, it is possible to easily peel off the adhesive tape for one round that has been used.
