Description

  The present invention relates to a holder for a wound tape body, and more particularly to a holder for holding a wound tape body that is wound around a paper-made cylindrical core body that easily generates abrasion powder by sliding contact.

Various winding tapes typified by cellophane tape, vinyl tape, cloth tape, and the like are formed by winding dozens of tapes having a predetermined width around the outer peripheral surface of an annular core having a central hole. Generally, in this type of wound tape, a core body in which cardboard is formed in a cylindrical shape is used. The most common method of using such a wound tape body is to place a plurality of fingers of the user's hand in the center hole of the core body of the wound tape, and then gently grip this with the fingers as a support shaft. The tape was pulled out from the wound tape while rotating the tape. In addition, such a winding tape may be used by being mounted on a winding tape support or a tape cutter. As such a winding tape support, the invention disclosed in Patent Document 1 is known. ing.
