SLIDE FASTENER, BAG HAVING SLIDE FASTENER ATTACHED TO MOUTH THEREOF AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To fill a bag having a fastener attached thereto with content from the mouth of the bag after the bag is erected and to prevent not only the damage of the appearance of the bag after hermetic sealing but also the damage of the content. SOLUTION: The fastener 10 has such a structure that male and female stripes 14 and 15 are formed to a track 11 formed into a U-shape along the upper ends 12 and 13 thereof and a slider 16 is attached to both stripes. When the bag is manufactured, the fastener 10 is inserted in the mouth 19 of the bag 17 and the single side of the track 11 is sealed to the mouth 19 of the bag 17 while the opposite side thereof is held to an unsealed state. The bag 17 is erected to be filled with the content from the unsealed part of the track and the unsealed part is subsequently sealed to hermetically seal the mouth 19 of the bag 17. When the mouth 19 of the bag 17 is opened, the fastener 10 is opened to tear the track 11.
