Definitions

  • the present invention relates to a shopping-bag utilizable for collecting garbage.
  • GB 2 187 164 A discloses a bag or sack-like article which is convertible between a carrier bag and an elongated sack-like mode.
  • the bag has an open end and a closed end, with a transverse line intermediate of said ends about which the upper portion of the bag is foldable over the remainder of the bag.
  • Handles utilizable in the carrier bag mode are connected to opposite inner surfaces of the bag.
  • the folded portion of the bag is freely hanging over the the remainder of the bag and does not participate to the strength of the bag.
  • the main object of the present invention is now to provide an improved bag which is suitable both for hand-conveyance of goods and, in a subsequent use, for collection of garbage.
  • a bag 10 comprises a tubular shopping-bag 12 of a synthetic material, of the kind typically used for the hand-conveyance of goods, which is provided with handles 14, 16 at one of its ends, is closed at the opposite end by means of a first transversal weld S1, and has lateral gussets 20, 22.
  • shopping-bag 12 is wrapped in a tubular lining 18 made of a synthetic material and extending adjacent to the shopping-bag along its entire perimeter, and is bonded to said shopping-bag by a second transversal weld S2 extending near the open end of the bag, at the base of handles 14.
  • Lining 18 is also bonded to shopping-bag 12 along said first transversal weld S1 and has a perforation P extending parallel to, and in proximity of, the weld.
  • lining 18 is substantially a second bag that houses the main shopping-bag 12.
  • the bag When used for the hand-conveyance of goods, the bag is configured as shown in Fig. 1 , i.e., is has the shape of a conventional shopping-bag such as those dispensed in markets or supermarkets. Nevertheless, handles 14, 16 are more rugged since they are formed of a double layer of material.
  • lining 18 is teared along perforation P and is folded to assume the configuration shown in Fig. 2 , which is almost double-sized with respect to the previous one.
  • the bag can also be used in association with rigid bins, in a way similar to a conventional garbage-bag manufactured ad hoc.
  • Bag 10 can be mass produced in a processing line for conventional bags, by suitably modifying the line for the application of lining 18.
  • a method will be now disclosed for the manufacture of gussetless bags, but it is understood that, if desired, gusseted bags can be manufactured by merely inserting an additional, longitudinal-folding step, as will be mentioned below.
  • a pair of elongated ribbons 28, 30, made of a synthetic material unwind from respective parallel cylinders 24, 26.
  • One of the ribbons (ribbon 28 in the figure), which is to form lining 18, is slightly wider than the other ribbon, and the above-said transversal perforations P are cut in it at constant intervals.
  • Ribbons 28, 30 are then conveyed to overlap onto each other and are welded to each other by means of transversal welds S2 ( Fig. 4 ). Thereafter, the ribbons are longitudinally folded along a middle line L ( Fig. 5 ), and their rims are mutually joined by longitudinal welds SI and SE, respectively made on the inner ribbon 28 and on the outer ribbon 30 ( Fig. 6 ), thereby forming two flat tubes received one within the other and parted at intervals by the welds S2. Finally, as shown in Fig.
  • a transversal double-weld S1, S3 is made with an intermediate cut extending along a transversal line T in order to split the tube into bags, and then each bag is punched at F between the intermediate cut and the weld S2 to form handles 14, 16.
  • gussets can be formed by merely introducing an additional step between the steps shown in Figs. 6 and 7 , in which the lateral borders of the flat tube are longitudinally, inwardly folded, in a known way for the person skilled in the art.
  • FIG. 8 A second embodiment of the bag, which is similar to the above-described first embodiment, is shown in Fig. 8 , wherein a lining 118 with perforation P is welded inside the bag. Therefore, also in this case, in order to increase the size of bag 110, lining 118 is torn along perforation P and is then extended outwardly, thereby causing the bag to assume the configuration of Fig. 9 , with the handles outwardly hanging from it.
  • the process for the manufacture of this second embodiment is similar to the above-described process, but perforation P will be made on the ribbon 30 that will constitute the inner wall of the bag.
