Reference numeral 1 denotes a pedestal, which is integrally provided above a base 2 which can be placed on a table or the like, with a lower portion of a collar body 3 whose collar surface is vertical. Perimeter wall 4 with a slight width on the periphery of 3
The outer cylinder receiving body 5 is projected from the collar body 3 with a gap equal to or more than the thickness of the adhesive tape winding body described later in the peripheral wall 4, and the inner cylinder receiving body 6 having an appropriate diameter is provided inside thereof. A notch 7 is formed in a part of the peripheral wall 4 by projecting, and a claw body 8 is provided in the notch 7.
Is formed so as to extend in the circumferential direction of the peripheral wall 4 and the tip end thereof serves as the peeling blade 9 that is close to the circumferential direction of the outer cylinder receiver 5, and the claw body 8 has appropriate elasticity. It is formed by fixing the base end portion to the peripheral wall 4.

The claw body 8 is slightly narrower than the width of the surface of the pressure-sensitive adhesive tape on which the pressure-sensitive adhesive is not applied, which will be described later.
Is formed so that its tip is directed in the circumferential direction or slightly inward, and protrudes outward in the thickness direction at the middle portion of the nail body 8 so that it is easy to hang a finger and the peeled adhesive-uncoated surface portion is in the vertical direction. Projection 1 that was designed to stand up at a steep angle
It is desirable that 0 is formed.

Reference numeral 11 denotes a lid, and a holding outer cylindrical body 13 rotatably fitted to the outer side of the outer cylindrical receiving body 5 is projectingly provided on one surface of the brim body 12 facing the brim body 3. A rib 14 is provided on the outer surface of the holding outer cylindrical body 13 so as to tightly fit an adhesive tape winding body, which will be described later, and a through hole 15 is formed in the central portion of the collar body 12. .

Reference numeral 16 is a locking member, which has a knob portion 17, and one of which is provided with a protruding portion 18 which is fitted into the through hole 15 and fitted into the inner cylinder receiver 6. ing.

The inner cylinder receiver 6 and the locking member 16 are fitted so that they are rotatable with respect to each other or the collar body 12 supported by the locking member 16 is rotatable. It is formed so that if it is pulled out strongly, it can engage and disengage in a detachable manner. Reference numeral 19 is a protrusion formed on the protrusion 18 for engaging the concave and convex portions.

Further, the cover body 11 is provided with a rotation lever 20 projecting near the peripheral edge of the outer surface of the collar body 12. Lever 2
As for 0, only one piece may be formed on the collar body 12, or two or more pieces may be formed. Four pieces are formed at equiangular positions from the center in the figure, and the lid body 11 is rotated by about 90 °. I made it easy.

Thus, the adhesive tape cutter has a lid 11
The holding outer cylinder body 13 is fitted to the outer cylinder receiver 5 of the pedestal 1, and the locking member 16 is locked to the inner cylinder receiver 6 through the through hole 15.

Reference numeral 21 denotes an adhesive tape winding body, and the core tube 22 has O
A long adhesive tape 23 made of synthetic resin made of PP or other appropriate material is wound. The pressure-sensitive adhesive tape 23 is formed as a pressure-sensitive adhesive-coated surface 24 on which a pressure-sensitive adhesive is applied except for a slight width portion on one end side of the winding body, and a pressure-sensitive adhesive-uncoated surface 25 or a release surface having a release layer on the above-mentioned slight portion. The boundaries 26 of both parts are continuous in the longitudinal direction. A slit (cut) 27, which is parallel to the winding direction at a desired interval and is cut in the radial direction of the winding state, leaves the end of the pressure-sensitive adhesive-uncoated surface 25 slightly, and the slit is substantially formed. It is formed over the entire width.

The adhesive tape roll 21 is made up of the adhesive tape 2
Since 3 is adhered by the adhesive in the wound state and the end of the adhesive-uncoated surface 25 is continuous in the longitudinal direction, even if the slit 27 is formed, it is in the wound state. Is maintained as it is, it does not lose its shape and part does not flicker. At the time of use, the adhesive-uncoated surface 25 portion between the adjacent slits 27, 27 is peeled off,
If this is picked up and peeled off, the unit adhesive tape 28 with one unit between the adjacent slits 27 can be obtained.

Further, in the cutter with an adhesive tape, the locking member 16 of the adhesive tape cutter is removed, the lid 11 is removed, and the adhesive tape winding body 21 is fitted to the holding outer cylindrical body 13 and the collar body 12 is attached. After substantially making contact, the lid 11 is fitted again, and at this time, the claw body 8 is elastically deformed outward by the finger and the adhesive tape winding body 21 substantially makes contact with the collar body 3. In this way, the lid 11 is fitted and the locking member 16 is locked. The adhesive tape winding body 21 is fitted by the ribs 14 so as to rotate integrally with the holding outer cylinder body 13, and the adhesive tape winding body 21 is fixed by the collar bodies 3 and 12 at a predetermined position without coming off. The blade 9 of the claw body 8 is in pressure contact with the portion 25 of the adhesive-uncoated surface.

In order to operate the cutter with the adhesive tape, the lever 20 may be pushed with a finger to rotate the collar body 12,
At the same time, the holding outer cylinder body 13 and the adhesive tape winding body 21 rotate. If four levers 20 are formed, the rotation can be repeated simply by repeating the operation of pushing the lever 20 on the front side to the lower side of the front side, which makes the operation extremely convenient.

When the adhesive tape winding body 21 rotates, as shown in FIG.
As shown in FIG. 5 and the like, the blade 9 at the tip of the claw body 8 is always in contact with the surface of the adhesive tape 23 on which the adhesive is not applied with an appropriate elastic pressure P. It easily gets into the back side of the adhesive-uncoated surface 25 where the layers are separated because the adhesive is not applied, and as a result, the adhesive-uncoated surface 25 is lifted above the nail body 8 and at the same time, the adhesive is not applied. The unit adhesive tapes 28, each of which is separated by each slit 27 as shown in the drawing, by easily cutting the connection or adhesive portion 29 at the end of the agent-uncoated surface 25
The non-adhesive coated surface 25 is easy to pick and stands up independently.

As described above, by simply turning the adhesive tape winding body 21, the adhesive-uncoated surface 2 of the plurality of unit adhesive tapes 28 is rotated.
Since 5 automatically rises in a line, the adhesive-coated surface 24 is peeled off by sequentially pulling them, and a plurality of unit adhesive tapes 28 can be obtained.

It is most preferable to use the pressure-sensitive adhesive tape cutter having the above-mentioned structure by mounting the pressure-sensitive adhesive tape roll 21 having the above-mentioned structure, but use a pressure-sensitive adhesive tape roll having perforations instead of the slits 27. can do. In addition, a long adhesive tape winding body having no slits or perforations, or an adhesive tape winding body obtained by imparting a tearing directionality to the width direction of the winding body, and a long length having no adhesive-uncoated surface 25. Even when using a lengthy adhesive tape roll, the tape tip portion can be peeled off by the blade 9 of the claw body 8.

FIG. 6 shows an embodiment different from the above. In this embodiment, instead of the lever 20,
The outer peripheral surface of the collar body 12a of the lid body 11a is formed as a knurled surface 20a having an appropriate roughness. Other configurations are the same as those in the above embodiment. In the case of this configuration, the collar body 12a may be gripped and rotated, or the outer peripheral surface thereof may be rubbed with a finger and rotated.

The form of the base 2 is arbitrary, and a pencil stand or a storage part such as a stapler may be connected continuously. It is also effective to attach a weight in order to have stability in placement.

Also, if the blade 8 is formed so that the blade 9 portion is elastically approached in the direction of the outer cylinder receiver 5,
The configuration is arbitrary. For example, a base portion of an independent claw body is axially attached to the peripheral wall 4 portion, and a spring mounting portion is formed between the claw body and the peripheral wall 4 portion to interpose a spring, and the tip portion of the claw body is always an outer cylinder receiver. It is also possible to have a structure in which the claw body is biased in five directions, and a tab portion that can be pulled up against the spring is formed.

Further, as long as the adhesive tape winding body 1 is attached to the holding outer cylindrical body 13 so as to be rotatable, each part is not limited to the above-mentioned configuration. It goes without saying that the wall thickness varies depending on the material, and if the wall thickness is thick, the form is thinned.

[0029]

According to the present invention, the mounted adhesive tape roll is rotated by a one-touch lever operation or the lid rotation operation, and at the same time, a desired nail is attached to the adhesive tape roll by the attached nail body. It is possible to provide an adhesive tape cutter and a cutter with an adhesive tape in which the unit adhesive tape can be peeled off conveniently, and the cutter has an extremely simple structure, so that the mechanism is stable and easy to operate. . In particular, since there is easiness of rotation with a finger and an arbitrary rotation angle, it is easy to select the number of peeled adhesive tapes as desired.

Further, since the peeling position of the adhesive tape can be formed on the upper part of the collar body, it is convenient that the unit adhesive tape can be easily taken from any direction of the cutter with the adhesive tape when peeling the unit adhesive tape from the adhesive tape roll. .
