Description

[Detailed explanation of the invention] (1) The cutting blade of a cutting tool for thin adhesive tapes made of cellophane, polyester, etc. is usually used with a serrated metal or resin blade for safety in use and ease of cutting. Knife-shaped cutter blades, scissors, etc. are used to cut tapes, sheets, and films.
There are many inconveniences in cutting, and there is a high risk of cuts to fingertips, etc.

The cutting blade holder according to the present invention has been researched and developed to improve these drawbacks and inconveniences in use, and is made of cellophane, hard polyester film, thick vinyl adhesive tape, wide film,
The present invention provides a cutting blade holder for a cutting instrument such as a sheet.

(2) As for the features and effects of the cutting blade holder of this invention, the cutting blade may be a razor blade or a straight metal cutter blade. For safety in use and to prevent the risk of cuts and other hazards, the needle-like protrusions of the holder protrude 0.1 to 0.4 mm from the blade edge and are spaced equally apart across the blade width at 3 to 4 mm intervals. Therefore, even if a fingertip presses or comes into contact with the blade edge of the cutting tool, the protrusions of the holder will come into contact with the fingertip, eliminating the risk of the fingertip sliding and causing cuts. In the embodiment, the height of the needle-like protrusions of the holder from the blade edge is 0.2 mm, and tests of fingertip pressure and sliding with protrusions spaced 4 mm apart have confirmed their safety.
Also, from the results of cutting tests on tapes and films, etc., it was not found that the cutting effect was lost due to the needle-like projections on the width of the blade tip, but rather the needle-like projections of the holder penetrate the tape, and the tape does not slip, especially when cutting non-adhesive tapes, making cutting more effective. Furthermore, when cutting wide sheets and films, as is the case with knife cutters, the cutting blade tends to run diagonally and bend, but with the cutting blade of this invention, the projections stop the blade from running, and since the cutting blade needs to be pressed appropriately, the blade does not run too far and can be cut extremely effectively.

In particular, when cutting various types of plastic adhesive tapes, conventional tape cutters and the like use saw blades, resulting in jagged edges, but with the cutting blade of the present invention, the cuts are straight and sharp, so they can be applied neatly.

(3) The cutting blade holder according to the present invention has dimensions of 7 mm in height, 15 mm in width, and 3 mm in thickness or less when used with 12 mm wide adhesive tape, making it easy to design the cutting tool and fix the cutting blade. It has a structure that can accommodate any cutting instrument design.

Furthermore, for wide tapes, etc., it is possible to easily provide a cutting blade holder with a blade width of 50 mm to 100 mm, if necessary.

If the material of the cutting blade is stainless steel, it can be effectively used as a durable cutting blade holder that will not rust depending on the place of use and the cutting tool.

Claims (1)

[Scope of utility model registration request] A cutting blade holder used for cutting instruments for adhesive tapes, sheets, and films such as vinyl, which has a combination structure of a metal blade and a holder for fitting and fixing to the cutting instrument, excluding the cutting edge width surface of the cutting blade. It has a metal or plastic holder structure that wraps both sides, and the end of the holder parallel to the width of the blade is cut into a semicircle or V-shape.The needle-like protrusions of the holder are evenly spaced on the width of the blade. The opposite end of the holder is tightly fixed to the lower part of the blade edge width, and the opposite end of the holder has a circular or cylindrical structure to facilitate fixation to the cutting tool. Claims for registration of a utility model for a cutting blade holder used for cutting tools for various adhesive tapes, film sheets, etc., in which the blade width surface does not lose its cutting effect on tapes, etc., and there is no risk of cutting fingertips.
