[Problems to be solved by the device]

 Adhesive tapes are used everywhere in society, and there are many ways to use them. A cutting edge wrapping tape cutter was created that made it easier to peel off the adhesive tape pasted from this background. However, most of these are the types that are used on the desk as described above. However, the adhesive tape is often used by carrying it around, such as holding it in your hand or putting it in a pocket.In addition, you may want to fold the cut end of the adhesive tape to make it easier to peel off the attached adhesive tape later. is there. One of the reasons that the present invention was considered is the bandages used by nurses in hospitals. Adhesive plasters are carried by nurses at all times, and are used very frequently in everyday life such as gauze, bandages, and fixing drip tubes. Particularly in this case, the tape is used for the patient and the human body. When trying to peel off the tape attached to it, it is not preferable to scratch the end face with the nail on the skin. It is very convenient if the cut end is folded back so that it can be easily peeled off later. Here is a typical use case where you want to make it easy to remove the tape that is portable and that has been folded and pasted. There seem to be many such examples, and the present invention was devised to solve such problems and make them easier to use. Conventional cut-end folded tape cutters are mainly targeted at cellophane tapes for office work, but the present invention is applicable to all tapes including adhesive plasters.

【Example】

 The present invention will be described with reference to the embodiments shown in the drawings. FIG. 1 is a view in which the lid 6 is opened to mount the adhesive tape 8, and FIG. 2 is an external view in which the lid 6 is closed. FIG. 3 shows the usage state, and the tape cutter of the present invention is used by holding it with one hand and supporting and cutting the adhesive tape 8 with the other hand. In this embodiment, it is assumed that it can be carried in a pocket, so that it fits in the palm of the hand, but it is held in a hand, carried on a wagon, or carried in a bag. Since it can be carried in and carried around and used in a variety of ways, it does not matter if it is larger so long as it can be operated with one hand. This will be described in detail with reference to FIG. The case 1 is integrally provided with a fixing plate 1b having a tape fixing surface 1a on its upper surface. The side cutter plate 2 has a tape support surface 2a and a cutter 3 on its upper surface, and is rotatably supported by a fulcrum shaft 4. The cutter plate 2 is constantly urged by the force of the spring 5 in a direction away from the fixed plate 1b, and is stopped at a fixed position by a stopper 1c provided on the case 1. When the cutter plate 2 is rotated in the direction of the fixed plate 1b against the bias of the spring 5, the tape fixing surface 1a and the tape supporting surface 2a come close to each other and come into contact with each other. Next, a part of the case 1 has a lid 6 to which an adhesive tape 8 can be attached, and can be opened and closed by a shaft 7. The lid 6 has an adhesive tape mounting portion 6a, and when the lid 6 is opened, the central hole of the adhesive tape 8 can be fitted and mounted. The case 1 has a locking hole 1d and the lid 6 has a locking projection 6b, which are engaged and fixed when the lid 6 is closed. When opening, the lid 6 is pulled strongly to disengage.

The usage will be described with such a structure. The holding method is as described in FIG. With the hand different from the one holding the tape cutter, first pull out the adhesive tape 8 for the required length as shown in FIG. 4, and push it down to make the tape fixing surface 1a on the upper surface of the fixing plate 1b as shown in FIG. Then, the tape is hung on the tape supporting surface 2a on the upper surface of the cutter plate 2 and the cutter 3 to be adhered. Next, in this state, the adhesive tape 8 is cut by the cutter 3 as shown in FIG. The work up to this point is the same as that of a general tape cutter, and if it is not necessary to fold back the cut end, this work can be repeated, and conventional usage without wrapping can be achieved. Since the cutter plate 2 is pressed against the stopper 1c by the spring 5, the cutter 3 is similar to being fixed.

In order to make a turn at the cut end, the cutter plate 2 is rotated in the direction of the arrow against the bias of the spring 5 as shown in FIG. 7 from the state of FIG. In this way, the adhesive tape portion hung between the tape fixing surface 1a and the tape supporting surface 2a is bent upward, and the root portion is adhered to form a ring shape and the cut end is folded back. Further, the tape fixing surface 1a and the tape supporting surface 2a are inclined so that the adhesive tape surely folds upward so as to form a ring shape so that the tape fixing surface 1a and the tape supporting surface 2a have a V shape when they are close to each other. The actual operation for making a turn may be performed by pulling the cutter plate 2 by pulling it with the index finger of the hand held as shown in FIG. When the adhesive tape 8 is pulled out again after it has been pulled up and folded back, the fingers are swung back to return the cutter plate 2 to the original position, and the adhesive tape 8 is cut as shown in FIG. A piece of tape is at hand. Since the state shown in Fig. 6 remains on the tape cutter side, when you use it next time, you can cut it as it is and it will not be folded back, and if you pull the cutter plate 2 it will be folded back, so that you can always use either tape properly. Become. If the operator can rotate the cutter plate 2 with his / her finger holding the tape cutter, the adhesive tape can be cut and folded back smoothly. What if the operation of rotating the cutter plate 2 with the hand of pulling out the adhesive tape is performed without using the present invention? From the state shown in Fig. 6, rotate the cutter plate 2 in the direction of the arrow as shown in Fig. 7 with the hand that pulls out the adhesive tape, and fold the cut end of the adhesive tape. Next, you have to take your hands off the cutter plate 2 to pull out the adhesive tape with the same hand. When the hand is released, the cutter plate 2 tries to return to its original position due to the urging force of the spring 5, so that the adhesive tape folded back in a ring shape is about to be peeled off. If the spring 5 is strong or the adhesive strength of the adhesive tape is weak depending on the temperature conditions, it will actually come off. If you can pull out the adhesive tape with your other hand while keeping this state by rotating the cutter plate 2 with your fingers holding the tape cutter as in the present invention, there is no worry of peeling. In the present invention, the index finger is used, but any other finger may be used as long as it is a finger having a tape cutter.

As shown in FIG. 2, the case 1 and the lid 6 cover the entire tape ring except for the opening 1 e that guides the adhesive tape 8 to the cutter 3. The cutter plate 2 is also surrounded by the side plate 1f of the case 1. Although there is a notch 1g for operating the cutter plate 2 with fingers, the upper and lower sides are still guarded. This is done in order to protect the adhesive tape and the cutter plate 2 when carrying it in your hand or carrying it in your pocket so that you can carry it easily.

The reason for attaching the adhesive tape mounting portion 6a to the lid 6 as shown in FIG. 1 is as follows. When the adhesive tape mounting part 6a is attached to the case 1 side, in order to mount the adhesive tape 8, a hole having a diameter larger than that of the ring of the adhesive tape is formed in the case 1, the mounting is performed from here, and the lid is further attached to this. I have to. If such a large hole is made, the strength of the case 1 becomes weak. If the lid 6 is supported by the shaft 7 and can be opened and closed while rotating as in the present invention, the lid can be installed when it is opened, so a lid that is about half the size of the adhesive tape ring can be used.

If a grip portion 9 is provided on a part of the case as shown in FIG. 8, it is easier to hold. The recessed portion 1h is an important recess for applying the middle finger to facilitate holding the case.

[0011]
