Abstract

338,170. Rawlins, J. D., and Paper Sacks, Ltd. Aug. 14, 1929. Paper bags.-A multi-ply bag having a valve opening in one corner is provided with a valve-forming extension comprising an inserted strip of material extending down to the lower end of the bag. A singleply strip of material 14 is folded to fit snugly the gusset 11 of a bag, its lower end reaching to the bottom of the bag and its upper end extending above the top edge thereof. The value is formed in the usual manner and the strip secured by the sewing at the top and bottom of the bag. An insertion is used at each side of the bag, and the flaps of the valves so formed overlap about the longitudinal axis of the bag, one valve serving for filling the bag and the other as an air vent.
