发明名称 DRAW TAPE BAG WITH TWO SINGLE DRAW TAPES AND METHOD OF MANUFACTURE
摘要 F-4471 DRAW TAPE BAG WITH TWO SINGLE DRAW TAPES AND METHOD OF MANUFACTURE A draw tape bag with two single tapes has a front wall and back wall of flexible sheet material joined to each other along edges of the bag. Tubular channels extend along opposed transverse top edges of the front and back walls. The channels define an open mouth for the bag. Each of the channels has openings at the opposite ends of the top edges of the bag. A tape extends through each of the channels. One of the ends of each of the tape is attached to the opposite side edges of the bag beneath the openings in the channels and the other end of the tape extends through the respective opening at the other ends of the channels so that the tapes cross in their respective channels, whereby when the tapes are pulled, the top of the bag is drawn tightly together. A method of forming this draw tape bag is also disclosed.
