339,938. Rawlins, J. D., and Paper Sacks, Ltd. Aug. 14, 1929. Paper bags; sacks and the like bags.-In closing a paper sack or bag, stapling or stitching is provided along each side of the mouth of the open end of the bag, and may secure a thread or cord thereto at intervals, a closure being formed by threading a tie beneath opposite portions of the stapling, stitching or thread and securing the ends of the tie in such a manner that the sides of the mouth are held together. Short slits g made in the ends of the mouth of a bag a permit reinforcing strips i to be placed over the opposite sides of the mouth. The upper edge of a tongue or flap v is inserted in the reinforcement on one or each side of the mouth and the sides, tongue and reinforcement are sewn or stapled together, a cord m being secured at intervals to the reinforcement by the sewing &c. The strips extend beyond the edges of the bag and are secured together at their ends by reinforcements r sewn on to them. In a modification, a single reinforcing strip w, Fig. 6, surrounds the mouth of the bag and a single flap z having its ends secured together at t is provided. To close the bag, the flaps v or flap z are drawn upwards and rolled downwards to close the mouth as shown in Fig. 6 and a tie is secured to the cords m at one end of the mouth. The tie is drawn alternately beneath the cords m until the other end of the mouth is reached, when it is drawn tight and secured to both cords. Alternatively the ends of the tie may secure the ends of the mouth in bunch form.
