Definitions

  • the invention relates to the technical field of paper packaging for products containing fatty substances, these products being in granules or in powder and being sensitive to the environment (light and atmosphere), as particularly pet food or farmed animals, dry food or phytosanitary products in grains or powders.
  • the invention relates more particularly to bellows packaging and rectangular bottom of type small and medium capacity, corresponding to a weight in the range of five hundred grams to fifteen kilograms.
  • a third drawback is the use of two layers of paper strong for the realization of the body of the package. Under the effect of fat contained in food, it is possible that the inner sheet of strong paper macula and, in the long run, that the outer leaf is also stained. The packaging will then have a less favorable aspect to the sale. Moreover, under the effect claws of cats or dogs, the packaging may be perforated or split, with the disadvantages mentioned above.
  • WO-A-97/46461 discloses a packaging for food, in particular for pet food, consisting of a bag made of gusseted and looped paper, this package being provided with loop strips and hook tape as marketed under the trademark Velcro ®.
  • a first band is placed on the inside of a first large side of the bag, neighborhood of the upper free edge of this first large side.
  • the second band is placed on the outer side of a second large side of the bag, this second large side being provided on its upper free edge with a notch placed in look at the first strap.
  • a fold line allows the flap from the mouth of the bag the two fastening strips then facing through said notch.
  • FR-A-2 791 040 discloses a bellows bag for the packaging of bulk products such as animal feed.
  • the bag can be stored flat, filled, then closed without requiring any modification of the corresponding workstation.
  • the bag is made using a sheath made of synthetic material such as polyethylene.
  • the bag is without means allowing it to be closed, a dump opening being formed by a pre-cut line placed in an angle of the bottom of bag, opposite the handle of the bag.
  • US 6,279,298B discloses a bag comprising a bellows bottom and an open upper part with a fastening band of which a first fin is fixed on the inner face of a first bag panel and a second fin being free. After filling of the bag, the second fin will be attached to the inner face of a second panel.
  • the invention relates, in a first aspect, to a bag made of single or, advantageously, double-fold paper, provided, in the vicinity of its opening, a band supporting means of closure, this band forming two sails substantially facing each other, only one of the two sails being fixed on the inner face of the inner fold of the bag before filling and its closure.
  • the invention relates to a bag such as presented above, this bag being closed and filled, the second veil of the band supporting the closing means being fixed on the inner face of the fold inside the bag.
  • the invention relates, in a fourth aspect, to the use of a bag as previously presented for the packaging of food products for animals.
  • a bag such as presented above may be used for other purposes such as for example the packaging of litter for animals, or food products plant protection products in grains or powders, dry or slightly moist.
  • the bag 1 is of double fold type.
  • bag 1 includes two unassembled sheets of paper on all their surfaces contact but attached to each other on their edges, including their high edges and down.
  • the two sheets are fixed one to the other by an adhesive.
  • the outer sheet or fold is printable, the inner sheet or fold forming a fat barrier.
  • the inner ply is paper-based brown kraft on which polyethylene is applied, in particular by extrusion.
  • the bag is provided on the periphery of its mouth of two veils 2,3, whose external faces 2a, 3a are capable of being fixed on the inside of the inner fold of the bag.
  • the sails 2,3 are made of polymer base material polyolefin, capable of being welded to the extruded polyethylene of the inner ply of the bag.
  • the welding of the sails can be carried out by heating, by ultrasound or high frequencies.
  • the bag is provided with reversible closure means zip type.
  • the male sections 4 and female 5 of this type of closure are shown schematically on the Figure 1, it being understood that a large number of profiles exist per se on the market and can be used here.
  • the shapes of the profiles 4,5 of FIG. must therefore be seen as schematic.
  • a slider 6 allows the opening and closing of the zip, by separation male and female profiles 4,5.
  • the bag includes first-time witnessing means opening such as, in particular, frangible bridge connecting the cursor and one of 4.5 sections, this breakable bridge being broken during the first opening manual zip.
  • the two inner faces 2b, 3b are, where appropriate, weldable together to form a peelable assembly, for example by application to these two internal faces of a repositionable adhesive, a message pre-printed on the sails being unmasked as a result of the fur.
  • the two internal faces 2b, 3b are not weldable between they except on a colored band of assembly by welding, the separation of 2.3 veils unmasking this colored strip at the sight of the consumer.
  • One of the sails 3 is welded to the inside fold of the bag while the other sail 2 remains free.
  • the bags can be delivered flat and filled in the factory according to the technique conventional: unstacking the bag and conveying to the filling station where tongs hold open the mouth of the bag.
  • the zip closure does not hinder in no way the flow of products to be packaged in the bags.
  • the bags can be closed again in a single operation: a hot welding will ensure both fixing on the inner fold of the bag of the veil which remained free 2, and the peelable attachment or the possible welding of the two sails 2,3 between them.
  • the profiles 4.5 extend over substantially the entire width of the mouth of the bag 1, the sails 2,3 being masked in view by the two folds of the bag 1.
  • the bags are unstacked and brought to a first station, by a conveyor.
  • the bag is then opened thanks to the commitment of pliers in the bag.
  • the zip-sliders are unwound from a reel, the tape zip being provided with zones 7 in which the profiles 4,5 are crushed and welded together. These zones 7 are substantially equidistant from a length slightly less than the width L of a large side of the bag.
  • the coil of zip is unrolled step by step and is cut to the right of each zone 7.
  • the zip cut provided with its cursor, is then deposited in the bag and one of the sails 2,3 is fixed on the inner face of the inner fold of the bag.
  • the fastening of the veil is carried out at a temperature of the order of 230 ° C, under a pressure of the order of 0.4N for 15mm2, the welding time being of the order of 1.5 seconds.
  • the bag 1 can be provided with handles, to facilitate its grip, especially for weights greater than three kilograms. These handles, in paper, rope or plastic, are held by gluing, welding or stapling, especially between the two folds of the bag, as it is known per se.
