ABSTRACT:
A plastic grocery bag is provided with a tear-off coupon. The coupon is configured with the rest of the bag for rapid production and easy detachment from the bag. The plastic bag is fabricated from tubes of blown plastic. The tube is first collapsed and printed and thereafter folded at the side edges to form two "W" shaped folds along the bag sides. These folds permit the bag, when expanded, to accommodate the required containment volume. As a next step, the folded tube is both heat-sealed and cut to form sealed incremental folded tubes. These tubes are in turn cut at the bottom to form the bottom of the bag and at the top to form the paired handles on either side of an opening, which handles are characteristic of the T-shirt bag. Centrally of the top of the two handles, and for the purpose of holding a group of such bags together, there is configured on the forward wall and rearward wall of each bag a tab. When numerous bags overlie one another, the tabs of all the overlying bags may be joined together into a wicket. This wicket holds the overlying bags stacked as a group together. This wicket also allows the bags to be serially opened and filled with merchandise, typically at a check stand. The improved coupon of this bag is configured from material that would otherwise be cut from the vicinity of the bag opening when it is formed. Specifically, the coupon is printed and cut for placement between the folded "W" folds at the sides. The coupon is configured so as not to interfere with the tab. With these positioning constraints, the coupon is placed for each detachment by either a packing clerk or the toting shopper without otherwise damaging or interfering with overall functionality of the bag.
