Description

  The present invention relates to a tape cutter with a folding function capable of easily forming a folding for always maintaining a pulling end of an adhesive tape wound in a ring shape.

  Adhesive tape typified by cellophane tape is usually wound around multiple layers around a ring-shaped core, and the necessary length is peeled off from the winding end according to the application, and then cut and used. Yes.

  When the adhesive tape is used in the form of a ring, if the tape is thin like cellophane tape, it is difficult to peel off when pinching the peeled end.

  Therefore, conventionally, the left and right leg pieces of the cutter were inserted, including the core of the ring-shaped adhesive tape, and the adhesive tape peeled off was pressed against this cutter and cut, and the cut end of the tape stuck to the cutter after cutting. It is designed to make it easier to pinch the end of the tape.

  However, with this type of cutter, after cutting the adhesive tape, if the cut end of the adhesive tape comes off the cutter, it sticks to the outer surface of the ring-shaped adhesive tape, and when reusing, look for the position of the tip of the adhesive tape In addition, even if the tip is found, it is extremely difficult to peel it off and pull it out. In some cases, the pressure-sensitive adhesive tape is broken and many unusable loss portions are generated.

For this reason, there has been proposed a stationary desktop tape holder that can be stably placed on a desk or the like so that the lead-out end of the adhesive tape can be folded back (see Patent Document 1.2). Since these are stationary tape holders, even if a large amount of adhesive tape is used in offices, etc., it is not suitable for home use that requires little installation space and is expensive. It becomes.

  The present invention does not cause the peeled end of the adhesive tape to stick to the outer surface of the ring-shaped adhesive tape simply by attaching it to the ring-shaped adhesive tape without using a dedicated tape holder that requires a place, It is an object of the present invention to ensure a state in which it is always easy to peel off.

  As a means for solving the above-mentioned problems, the present invention provides a cutter having a lateral width corresponding to the width of the ring-shaped adhesive tape and having a serrated cutting edge at the tip, and a tip that is erected at a required distance from the cutter. Folding forming part having a non-adhesive treatment on the part, left and right leg pieces for slidably attaching the cutter and the folding forming part to the ring-shaped adhesive tape, and a base part of the folding forming part, and pulled out And a frame portion that forms a window hole through which the adhesive tape is inserted.

  According to a second aspect of the present invention, there is provided a tape guide protruding piece which is erected between the fold forming portion and the window hole and which is provided with a non-adhesive treatment at the tip portion.

  According to a third aspect of the present invention, a concave portion is provided in the center of the tip of the fold forming portion, and the adhesive tape is partially bonded by pinching the adhesive tape at the concave portion, and the tape folding end is fixed at that time. It is in.

  According to the present invention, in the case where the ring-shaped adhesive tape is used without using the tape holder, the peeled end of the adhesive tape is passed through the window hole of the tape cutter, and is guided onto the cutter via the upper end of the folded forming portion. Once the adhesive tape is pulled out to the required length and pressed against the cutting blade of the cutter, the adhesive tape is turned back by pinching the adhesive tape passing through the tip of the cut-back forming part. Even if the adhesive surfaces are bonded to each other and the tape cutter moves, the cut end of the tape will not stick to the outer peripheral surface of the ring-shaped adhesive tape. Can be removed without difficulty.

  Further, when the cut adhesive tape is affixed to the other portion and then peeled off, the folded portion can be used as a knob to facilitate peeling.

  In particular, since the fold forming portion is treated to prevent adhesion, even if the fold portion is formed, it does not stick to the fold forming portion and becomes difficult to peel off, and can be easily picked up.

  According to the second aspect, since the tape guiding protrusion is added between the folding forming portion and the window hole, the peeled end of the tape can be easily pulled out next time.

  According to the third aspect, after the tape is cut, when the adhesive tape straddling the folded forming portion is pinched with the fingertip, the adhesive surfaces are partially bonded to each other at the recessed portion, so that the folded state can be obtained more reliably. .

  FIG. 1 shows a perspective view of an embodiment of a tape cutter 1 with a folding function according to the present invention, and FIG. 2 shows a tape in which an adhesive tape 3 is wound around a peripheral surface of a core 2 in multiple layers (the present invention). Fig. 5 shows a state immediately after the tape is attached to the ring-shaped adhesive tape A) and the adhesive tape 3 is pulled out and cut.

  The tape cutter 1 has a lateral width corresponding to the width of the adhesive tape 3 and a cutter 4 having a serrated cutting edge 4a formed at the tip thereof. The tape cutter 1 is substantially spaced from the cutter 4 at a predetermined interval with respect to the cutter 4. Folding forming portion 5 erected at the same height, frame portion 7 forming window hole 6 through which adhesive tape 3 continuously provided and pulled out at the base of this folding forming portion 5 passes, and said folding forming portion 5 and window hole 6 and a guide piece 8 for guiding the tape, and a leg piece 9 for holding the pressure-sensitive adhesive tape A so as to hold the pressure-sensitive adhesive tape A. , 9. The leg pieces 9, 9 are folded so that the bent portions 9 a, 9 a at the tips thereof are aligned with the inner peripheral surface of the core 2, and the tape cutter 1 slides in the circumferential direction of the ring-shaped adhesive tape A using this as a guide. Installed as possible.

  The tape guiding protrusion 8 has a height that serves as a guide for guiding the adhesive tape 3 drawn out through the window hole 6 to the tip of the folded-back forming portion 5.

  The folded-back forming portion 5 has a concave portion 10 at the front end in the width direction, and the adhesive surface of the adhesive tape 3 is attached to a required range from the left and right protruding portions of the concave portion 10 and the front end of the tape guiding projection piece 8. A non-adhesive treatment 11 is applied by pasting or applying a non-sticking material, or by fitting a cap formed of the material.
