DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adhesive tape mainly used for a cleaning tool for removing dust, lint, hair and the like on a carpet by sticking.

[0002]

2. Description of the Related Art As shown in FIG. 8, in general, such an adhesive tape 2 is wound on a core 1 with an adhesive surface on the front side, and is configured as an adhesive roller. The surfaces of both ends 2a and 2b of the adhesive tape 2 are non-adhesive surfaces, and the sewing machine crosses from one end 2a to the other end 2b through the adhesive surface so that the adhesive tape 2 appearing on the roller surface can be easily peeled off. An eye 5 is formed.

[0003] A shaft of a cleaning tool is inserted into the core 1 of the adhesive roller, and by rotating the adhesive roller, dust on the carpet is adhered to the adhesive surface and removed. When a large amount of dust adheres and the adhesive strength decreases, the used adhesive tape 2 is cut off from the sewing machine surface 5 and the next adhesive tape is put out on the roller surface.

[0004]

When the adhesive tape 2 is peeled off from the perforations 5, the adhesive tape 2 is torn along one of the edges of the adhesive tape 2 along the perforations 5, but it often takes time for the first peeling. That is, it is difficult to grasp one end edge of the perforation 5 satisfactorily, and it is difficult to quickly separate the edge along the perforation 5. In particular, it is difficult to grip only one adhesive tape 2 on the roller surface, and a plurality of (mainly two or three) adhesive tapes 2 may be peeled off at once.

Accordingly, the present invention has been made in view of such a problem, and an object of the present invention is to provide an adhesive tape for a cleaning tool in which an adhesive tape can be easily and surely peeled off one by one. Aim.

[0006]

In order to achieve the above object, an adhesive tape for a cleaning tool according to claim 1 of the present invention comprises:
The surface of both ends is a non-adhesive surface, and an adhesive tape having a fragile portion traversing from one end through the adhesive surface to the other end is used as a cleaning tool for rotating an adhesive roller wound with the adhesive surface facing up. In the pressure-sensitive adhesive tape used, the fragile portion is characterized in that it has at one end at least a portion that causes the end to cross in a direction different from a direction in which the fragile portion extends in other portions.

In this pressure-sensitive adhesive tape, unlike a conventional pressure-sensitive adhesive tape, which is linearly crossed from one end to the other end, the fragile portion has a raised portion at one end. The protruding portion traverses at least the corresponding end in a direction different from the extension direction of the fragile portion in other portions. Therefore, the raised portion can be easily grasped, so that only the adhesive tape on the roller surface can be easily peeled off one by one. Further, it is possible to easily find from which end edge of the fragile portion the adhesive tape should be peeled off by the cause portion.

In the present invention, the fragile portion is not specified as long as the adhesive tape on the roller surface can be easily separated from the portion, and indicates a perforated line, a portion having a reduced thickness, and the like.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on embodiments. FIG. 1 is a perspective view in which the adhesive tape for a cleaning tool according to the embodiment is wound into a roll and configured as an adhesive roller. The adhesive roller includes a core 1 and an adhesive tape 2 wound around the core 1 with the adhesive surface facing up. The adhesive tape 2 has non-adhesive surfaces at both ends 2a and 2b, and has a perforation 5 as a fragile portion crossing from the end 2a to the end 2b through the adhesive surface. The perforation 5 has, at the end 2b, a portion 5a that causes the end 2b to cross the other portion (the end 2a and the adhesive surface) in a direction different from the direction in which the perforation 5 extends.
In addition, the end 2b is provided with a mark 7 for starting peeling in the vicinity of the protruding portion 5a.

The raising portion 5a and the mark 7 have a form as shown in FIG. 2A (a plan view of the adhesive roller). That is, the raising portion 5a has a curved shape obliquely crossing only the end 2b, and the mark 7 is composed of “↑” indicating the peeling direction and “PULL” indicating pulling. In the example shown in FIG.
b is provided not only on the end 2b but also on the adhesive surface, and extends in a direction different from the extending direction of the perforation 5 from a part of the adhesive surface to the end 2b. Also, in FIG. 3A, the raising portion 5c is a linear shape provided only at the end 2b, and in FIG. 3B, the raising portion 5d has a different pattern from that of FIG. Extending.

On the other hand, in FIG. 4A, the end 2b of the adhesive tape 2 is larger than the width of the end 2a, and the protruding portion 5e formed in the end 2b is a curved cut. In FIG. 4B, the provoked portion 5f is a straight cut. As described above, in the pressure-sensitive adhesive roller in which the perforation 5 is wound with the pressure-sensitive adhesive tape 2 having the perforation-causing portions 5a, 5b, 5c, and 5d and the cut-causing portions 5e and 5f, as described above, When the shaft of the cleaning tool is inserted and the adhesive roller is rotated, dust on the carpet adheres to the adhesive surface. When the adhesive strength of the adhesive tape 2 is reduced due to adhesion of dust or the like, the used adhesive tape 2 is caused to be peeled off from the portions 5 (af). At this time, the raising portions 5 (a to f) have the ends 2 b in a direction different from the extending direction of the other perforations 5.
Since the mark 7 is provided in the vicinity of the raised portions 5 (a to f) while traversing (and a part of the adhesive surface), not only can the mark 7 be used to easily find out where to peel off. Thus, the end of the used adhesive tape 2 (that is, the raised portions 5 (a to f)) can be securely grasped, and only the used adhesive tape 2 can be easily and reliably peeled off.

Further, as shown in FIG. 5, the raised portion may be formed in various patterns. In FIG. 5A,
The inducing portion 5e of each cut is formed entirely at the end 2b. In FIG. 5B, the inducing portion 5e and the inducing portion 5e 'which is line-symmetrical thereto are alternately formed at the end 2b. I have. In FIG. 5C, the raised portion 5e at the end 2b is changed to the raised portion 5e ″ at the end 2a.
Are alternately formed at both ends.

On the other hand, in FIG. 6, the raised portions 5E and 5e are formed alternately at the end 2b, but the width d1 of the raised portion 5E (the perforations 5 other than the raised portion 5E).
The distance between the portion and the edge of the portion 5E) causes the portion 5e.
(The distance between the perforation 5 and the edge of the portion 5e other than the inducing portion 5e). By providing the raised portions 5E and 5e in such a pattern, the end 2b including the raised portions 5E and 5e can be more easily grasped, and the used adhesive tape 2 can be more reliably peeled off one by one. become.

Although FIGS. 5 and 6 show a portion where a cut is caused, it is needless to say that a portion where a cut is caused may be provided. As shown in FIG. 7, the raising portions shown in each of the above embodiments may overlap at substantially the same position in a state where the adhesive tape 2 is wound in a roll shape. That is, the perforations 5 (including the protruding portion) of the adhesive tape 2 wound on the core 1 are aligned substantially on the same straight line. In this case, when the used adhesive tape 2 is peeled off, and the next adhesive tape 2 appears on the roller surface, the perforation 5 of the previous adhesive tape 2 is removed.
The next perforation 5 (including the cause portion) of the adhesive tape 2 is located at substantially the same position as the position (including the cause portion).

The perforation 5 including the causing part is
It may be formed before winding the adhesive tape 2 around the core 1 or may be formed collectively after winding. In the case where the tape is formed before winding, in order to align the positions of the perforations 5 as shown in FIG. 7, for example, a pulse motor is used, and the winding diameter of the adhesive tape 2 around the winding core 1 is increased. Let me
What is necessary is just to control so that the perforation 5 may always be substantially the same position on an adhesive roller.

[0016]

As described above, according to the first aspect of the present invention,
According to the adhesive tape for cleaning tool, the following effects can be obtained. (1) It is easy to peel off the adhesive tape. (2) The raised portion serves as a mark of the position where the adhesive tape starts to be peeled, and it is possible to easily find from where the adhesive tape should be peeled. (3) Only the pressure-sensitive adhesive tape on the roller surface can be easily grasped, and it can be easily and reliably peeled off one by one. (4) According to the configuration of the sixth aspect, the position of the start of peeling can be more easily found by the mark of the start of peeling.
