Abstract

PURPOSE:To enable the easy formation of a folded part at the tip part of an adhesive tape and allow the adhesive tape to be cut in free length by providing the center part of a cutter body with a fixed support piece having a receiving part at the tip part, and a moving support piece having a cutting edge and a receiving part at the tip part. CONSTITUTION:When an adhesive tape 2 is pulled upward through a tape guide 11 provided at the rear part of a cutter body 4, a cutter 3 recedes on the outer periphery of an adhesive tape roll 1 in association with the pull-out of the adhesive tape 2. When the pulled-out adhesive tape 2 is brought into contact with a cutting edge 8 for cutting, the adhesive tape 2 is lightly attached to the receiving part of a fixed support piece 5 and the receiving part 9 of a moving support piece 7. The fixed support piece 5 and moving support piece 7 are simultaneously held with finger tips. The moving support piece 7 thereby slides to the fixed support piece 5 side, and the adhesive tape 2 between them is folded by fingers to stick together, thus forming the folded part. The adhesive tape 2 is then pulled out by the required quantity and cut by the cutting edge 8.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention folds the tip end of an adhesive tape so that the adhesive tape once attached can be easily peeled off to form a non-adhesive portion, and can be cut at a free length, and The present invention relates to an adhesive tape cutter that can also be used for conventional cutting without folding.

[0002]

2. Description of the Related Art Conventionally, as a method of easily peeling off a pasted adhesive tape, another tape is pasted to the tip of the adhesive tape to form a non-adhesive portion, which is then pinched with a finger. In this method, another tape is required in addition to the adhesive tape, and the device is complicated, and it is difficult for anyone to easily make a portion that does not adhere continuously.

[0003]

Usually, when sticking an adhesive tape, since both ends of the adhesive tape are cut off, the entire adhesive tape sticks without a gap, and the adhesive tape will be peeled off later. When I said, it was so troublesome that I couldn't remove it easily. In this case, since the adhesive surface is held by a finger at the time of cutting, the transparent adhesive tape may have an unpleasant appearance because fingerprint marks are clearly left. Further, the method of applying another tape or the like to the tip of the adhesive tape is troublesome. The present invention solves them by a simple method.

Next, hold the adhesive tape roll with one hand, pull out the adhesive tape with the other hand through the tape guide on the rear part of the cutter body, and hit the blade to cut. At this time, the adhesive tape is lightly adhered to the receiving portion of the fixed strut piece and the receiving portion of the moving strut piece and remains. Next, when the fixed strut piece and the movable strut piece are pinched at the same time with the fingertips, the movable strut piece slides to the fixed strut piece side, and the adhesive tape between them is piled up and folded by the fingers to attach the adhesive surfaces to each other.
When you release the pinched finger, the moving support piece returns to its original position, and the tip of the adhesive tape that has been folded remains in the receiving portion of the fixed support piece. After that, the operation of pulling out the adhesive tape, cutting it, and making a fold can be repeated. Further, in order to produce a tape which is not folded, the above-mentioned fixed prop piece and the movable prop piece are not pinched with a fingertip, and the adhesive tape pulled out is directly applied to the blade to cut.
