- Adhesive tape is a thin film of long base material such as cloth, cellophane, craft paper, rubber, polyvinyl chloride, etc. coated on one side with an adhesive mainly composed of rubber or synthetic resin.
- this adhesive tape is distributed in the form of an adhesive tape. It is used for various adhesive purposes such as sealing of envelopes, bags, and lids of boxes.
- the adhesive tape When such an adhesive tape is used, the adhesive tape must be pulled out from the adhesive tape wound body and cut to a desired length. Is used.
- the tape tensioner is a tape holder that rotatably supports the adhesive tape roll. It has an adhesive tape and a cut-out part for cutting the pulled-out adhesive tape.
- the adhesive tape pulled out to the desired length can be easily cut without using tools such as scissors or a power knife, and bonded. It can be used for pasting to objects.
- the adhesive tape has a thin base material and the entire surface of the base material is coated with an adhesive, so peeling off the attached adhesive tape from the target is extremely troublesome.
- Met In other words, when peeling off the adhesive tape with the entire adhesive surface attached to the target object, the outer peripheral edge of the adhesive tape is turned up with a nail or the like to form a tab, and the tab is picked up with a fingertip. Since it had to be peeled off, the work of raising the picking margin was cumbersome and troublesome.
- Japanese Patent Application Laid-Open No. 2001-32078 proposes a technique of a pressure-sensitive adhesive tape force cutter capable of forming the polymerized portion as a non-adhesive pick portion. That is, the pressure-sensitive adhesive tape cutter disclosed in this publication has the following constitutions (1) to (4).

- the adhesive surface side is bent to an acute angle of approximately 45 degrees, it is further pressed into contact with the base block 22b (second guide portion) to be bent to approximately 180 degrees.
- the base block 22b has a wedge-shaped notch 23 at the upper part, and a pressing roller 22c is disposed immediately above the notch 23 near the inclined block 21. ing.
- the pressing roller 22c corresponds to the top block 22a in the first to third embodiments described above, and is replaced by the top block 22a and fixed to the opening / closing cover 5 to be provided.
- the base block 2 2 b is fixed to the fixed cover 4 integrally with the inclined block 21.
- the tension acting on the adhesive tape 2a can be reduced.
- the adhesive tape side edge 2aS can be smoothly and reliably folded back, so that the operation force at the time of pulling out is reduced and the operability can be improved as much as possible.
- the winding angle of the adhesive tape 2a to the pressing roller 2 2c is slightly increased and the adhesive tape 2a is wound so that the pressing force (pressing force) of the adhesive tape 2a becomes slightly larger.
- the adhesive surfaces facing the adhesive tape 2a can also be superimposed and bonded together with a pressing roller 22c, and installed on the downstream side.
- the non-adhesive portion serving as a knob for facilitating peeling of the adhesive tape is provided.
- the non-adhesive portion By folding back the side edges of the tape and superimposing it, it can be easily formed along the longitudinal direction, and the function of forming the non-adhesive part can be easily switched on and off, and the adhesive tape can be easily mounted. Can be performed.
- the opening / closing member is open, since the non-adhesive portion is not formed on the adhesive tape, both the adhesive tape with the non-adhesive portion formed and the adhesive tape without the non-adhesive portion are cut off.
- the versatility of this tape cutter can be increased.
- the pressure-sensitive adhesive tape of the present invention by providing a mark on the non-adhesive surface on the non-adhesive surface to indicate a substantially central portion in the width direction of the adhesive surface aligned with the non-adhesive part, The work of pasting to a suitable position can be easily performed.
