  • Patent number: 6776528
    Abstract: Cooperating strips respectively having loop-type and hook-type connector surfaces are passed through loops forming handles of carrying bags to retain the carrying bags as a group. The ends of the strips, which are typically taken from supply rolls have saw tooth ends, and are heat sealed for protection against fraying. In one embodiment, the strips are aligned end to end. In another embodiment, the loop-type and hook-type connections are staggered so that a first end of one of the strips lies intermediate the ends of the other strip, and whereby the opposite end of the first strip, after being passed through the handles of the bags is brought around so as to lie adjacent to the first end of the first strip. A method is provided for forming the hook-type and loop-type strips to prevent fraying due to use.
