BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pressure-sensitive adhesive tape holder, and an object thereof is to fold back the ends of the pressure-sensitive adhesive tape wound around the pressure-sensitive adhesive tape base at the same time when the pressure-sensitive adhesive tape is cut off so that the pressure-sensitive adhesive surfaces stick together. It is to provide an adhesive tape holder capable of

[0002]

2. Description of the Related Art An example of a conventional adhesive tape holder will be described with reference to FIG. A holder (A) for supporting an adhesive tape base (C) around which an adhesive tape (B) is wound, the adhesive tape base (C) being located at a rear position in the holder (A).
Is provided with a mounting portion (E) that rotatably attaches via a rotation shaft (D), and a cutter (F) that cuts the adhesive tape (B) is provided at the front position of the holder (A). It was.

However, as shown in FIG. 8, the pressure-sensitive adhesive tape holder having the above-mentioned structure can be used by easily pulling out the pressure-sensitive adhesive tape for a required length while the end of the pressure-sensitive adhesive tape is adhered to the cutter. However, if the end of the adhesive tape (particularly cellophane tape) peels off from the cutter and adheres to the adhesive tape that is wound around the adhesive tape base, the adhesive tape will stick to where it is used. There was a drawback that it was difficult to tell if there was an edge of the tape. In addition, an adhesive tape is adhered to a joint portion between a container and a lid fitted in the container in order to seal a can and a box filled with sweets and tea. If this adhesive tape is adhered to the joint part up to the end of the adhesive tape, it will be impossible to know where the end of the adhesive tape is when removing the lid from the container, so the manufacturer folds the end of the adhesive tape back. The adhesive surfaces were stuck together. However, the workability is poor because the end portions of the adhesive tape are manually folded back one by one to adhere the adhesive surfaces to each other (hereinafter referred to as a picking portion). Also, when the packaging material such as an envelope or a packed cardboard box was sealed with this adhesive tape without forming a knob at the end of the adhesive tape, the adhesive tape of the packaging material was adhered when the adhesive tape was peeled off. Since the part is easily damaged and this packaging material cannot be reused and a new packaging material must be used,
Since the packaging materials cannot be effectively used, there is a strong demand for the effective utilization of the packaging materials and thus the effective utilization of resources.

Therefore, according to the present invention, when the adhesive tape is separated, the ends of the adhesive tape wound around the adhesive tape base can be folded back so that the adhesive surfaces adhere to each other.
Even if the edge of the adhesive tape is peeled off from the cutter, it is possible to know where the edge of the adhesive tape is, and improve the work of sealing the can, box, etc., and use resources more effectively. It is a technical object to provide an adhesive tape holder that can be used.

[0005]

As a technical means for achieving the above object, the present invention has an adhesive tape holder configured as follows. That is, a holder for supporting an adhesive tape base around which an adhesive tape is wound, and this holder is a support portion for rotatably supporting the adhesive tape base via a rotation shaft and the adhesive tape is tensioned. The rotatable feed roller, the feed member for feeding the adhesive tape, and the cut member for separating the adhesive tape are provided between the support portion and the feed member. The member is rotatably provided, and a spring for holding the feed member in an upright state when no external force is applied is provided in the lower portion of the feed member, and an adhesive tape is provided on one side of the feed member. A guide portion having a rotatable guide roller is provided, a connecting portion that is rotatably connected to the cutting member is provided on the other side portion, and a cutter is provided on the upper portion of the cutting member. Mosquito The adhesive tape holder is rotatably provided close to the feed member and is provided such that the upper portion of the cut member is in contact with the upper portion of the feed member when no external force is applied. Pertain to.

[0006]

The adhesive tape is pulled out, the feeding member and the cutting member are tilted by the adhesive tape, and the upper portion of the cutting member that is in contact with the upper portion of the feeding member is separated from the upper portion of the feeding member. Adhesive tape is adhered to the upper part of the feeding member and the cutter, respectively. Therefore, when the adhesive tape is cut, the feed member and the cutting member move in the upright direction due to the strain energy of the spring provided in the lower portion of the feeding member, and the upper portion of the feeding member and the upper portion of the cutting member come into contact with each other again and the adhesive tape is folded back. The adhesive surfaces of the adhesive tape can be adhered to each other to automatically form the picked portion at the end.
