Abstract (en)
[origin: EP4144249A1] It is an object of the present invention to reduce generation of rust on magnets and breakage of tape due to intrusion of moisture, by heating and shrinking a heat-shrinkable resin tube used in a tape-shaped opening/closing tool including the magnets. The present invention relates to a tape-shaped opening/closing tool for an opening portion of an article. The tape-shaped opening/closing tool includes: a heat-shrinkable resin tube; a plurality of magnets arranged in the tube at regular intervals, wherein the magnets are enclosed in the tube in such a manner as to be positionally fixed by resin after the resin has been shrunk using heat. A method of the present invention is a method for manufacturing a tape-shaped opening/closing tool for an opening portion of an article, the method includes the steps of preparing a heat-shrinkable resin tube (12); arranging a plurality of magnets (13) in the tube at regular intervals; and heating and heat-shrinking the tube to fix the magnets.
