DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adhesive tape cutter that can cut an adhesive tape such as a cellophane tape or a gum tape from a desired place after the adhesive tape is applied, and can simultaneously perform a tape terminal process.

[0002]

2. Description of the Related Art As an adhesive tape cutter of this kind,
Conventionally, for example, there is one disclosed in Japanese Utility Model Laid-Open No. 6-73027.

[0003] This conventional technique is a tape cutter in which an adhesive tape wound into a roll is rotatably mounted in a support, the tape is fed out from a lower corner, and the tape is cut by a cutting blade. Around the inner surface of the open frame-shaped support, the bobbin of the adhesive tape is pivotally supported by the bobbin receiver and the adhesive tape is rotatably mounted on the support, and the lower side of the support on the tape adhesive surface side, near the tape terminal, A self-floating part called a cutting part having a roller for pressing the adhesive tape on the upper surface thereof, a tape guide, and a cutting blade for cutting the tape passing through the guide is provided with a tape temporary attachment for temporarily attaching the adhesive surface. It is an adhesive tape cutting machine provided with a tilting piece.

[0004]

In the above-mentioned prior art, the tape end portion cut after use for the first time is temporarily attached with the tape adhesive surface facing down as shown in FIG. The projecting portion slightly protrudes from the piece in a free state, and the protruding portion is not always located at the upper position in FIG. 2 of the above-mentioned publication and is easily moved by a small external force. There is an essential first serious problem that the dispensing adhesive surface is liable to self-adhesive to other places, and then the process is troublesome and may not be ready for immediate use.

[0005] Also, in this conventional example, at the start of the adhesion,
It is considered that the tape protruding portion suddenly extends from the position immediately after the cutting in FIG. 2 to the position on the lower surface of the tape guide in FIG. 3 only by pushing the tilting piece (cutting portion) in the drawing of the same publication. However, as shown in FIG. 2 of the prior art, a tape protruding portion existing in a narrow space between the temporary attaching piece and the roller is carefully picked out with fingers or tweezers, and the drawn portion is taped as shown in FIG. Since the adhesive tape can only be put into the state of starting to stick the adhesive tape when it is positioned below the guide, there is a second problem that handling is troublesome and unfamiliar persons cannot use it.

Further, from the above-mentioned state of starting adhesion (FIG. 3 in the above-mentioned publication), when the tape-adhesive surface is actually pressed against the surface to be adhered with a tape guide to start attaching, the tape-adhesive surface of the pressed portion is used. If the force is smaller than the adhesive strength of the tape to the temporary attachment piece, there is also a third problem that the above-mentioned pressing portion positioned at the angle is peeled off from the surface to be adhered and often becomes unusable.

Further, apart from the conventional example, the one described in Japanese Utility Model Laid-Open No. 5-81160 is well known. In this conventional example, when the tape is inclined, a main body provided with a cutting blade at a position where it comes into contact with the pulled-out adhesive tape is loaded so that the wound adhesive tape can be rotated, and the non-adhesive surface of the pulled-out adhesive tape is removed. A guide shaft that slides and supports one end of the rotating body so as to be rotatable is provided, and the other end of the rotating body is pulled out when the main body is tilted forward on the surface of the adherend. The attachment portion to which the adhesive surface of the adhesive tape is attached is provided at the tip, and the rotation guide body that rotates so that the tip of the rotating body exceeds at least the cutting blade position and restores after cutting is provided on the lower side. This is an adhesive tape cutter that feeds out a tip after cutting.

Accordingly, in this conventional example, similarly to the above-mentioned conventional example, the tape end portion cut after the first application is used, as shown in FIG. The portion protrudes slightly from the portion in a free state, and the protruding portion is formed as shown in FIG.
It is not always in the upper position, and it is easy to move even with a slight external force, so the protruding adhesive surface that is the lower surface is likely to self-adhesive to other places, after which the processing is troublesome, and it is not possible to use it immediately Also, the use of a tape feeding rotating body having a complicated structure (see FIG. 4 in the gazette) has many problems that the assembly is troublesome and difficult to use. Further, since each of the conventional examples is of a so-called "disposable" type, there is a common problem that it is uneconomical and also causes garbage pollution.

According to the present invention, in order to eliminate the above-described problems, most of the adhesive surface of the tape end portion cut after use of the tape is temporarily fixed and protected by a temporary tape fixing piece. The tape terminal in the temporary fixing protection state can be easily picked out with the fingers from the notch of the fixing piece so that the tape terminal can be pulled out and ready for sticking, and the desired cut portion of the tape after sticking can be cut easily and quickly. And to enable the exchange use of the adhesive tape.

[0010]

SUMMARY OF THE INVENTION It is an object of the present invention to provide an adhesive tape wound in a roll and rotatably mounted in a support having a shape that can be gripped by a finger, and the tape is passed through a vicinity of a cutting blade.

As described above, the present invention has the following advantages. Since most of the tape adhesive surface 2a in the vicinity of the tape terminal cut after use by sticking can be temporarily fixed and protected by the tape temporary fixing piece 6,
At the start of the next tape application, the notch 6
Since the tape terminal in the temporarily fixed and protected state can be easily picked and set to the pull-out sticking start state from a, there is a first effect that a quick and reliable tape sticking operation can be executed.

Further, at the end of the sticking, the tape sticking end 2B
Can be reliably and easily cut with the tip cutting edge 7 of the holding plate 8, and the rotation of the holding plate 8 after this cutting makes it possible to fully open the portion between the opening edges 5 and 5a of the support 1, that is, the tape exposed portion. There is also a second effect that the important handling around the tape can be performed easily and quickly.

Further, the support 1 of the pressure-sensitive adhesive tape cutter according to the present invention is formed by splitting the support in the tape width direction.
Since the tapes are assembled and assembled, the user can easily exchange the adhesive tape when the tape has been used up, and the supports 1, 1 and the holding plate 8 can be reused as many times as is economical. There is also a third effect that it is possible to reduce the pollution caused by disposable waste.

Further, even in the event of trouble such as adhesion of an adhesive substance oozing out of the adhesive tape due to a high temperature in the summer to an adjacent object, the holding plate 8 is supported by the pivot portion 8 thereof.
There is also a fourth effect that it is possible to open the tape largely between the opening edges 5 and 5a of the support 1, which is essential, so that the trouble can be easily handled by fully opening the tape exposed portion.
