Definitions

  • This .patent application for an industrial utility model concerns a knapsack type bag with a closing seal, in plastic or paper material. Closing of this bag is automatically effected by pulling the string which enables the said bag to be gripped and more specifically placed on the shoulders like a knapsack.
  • the model is absolutely brand new and can be included in the range of plastic or paper bags in which purchased goods are normally consigned nowadays. It is manufactured, following current production techniques, from a tubular sheet, closed at one end underneath a supporting base, which actually makes up the bearing structure of the bag, which is provided with suitable closing and/or gripping means at its open edges.
  • the closing and gripping means are both made up of a string which is passed through holes especially made along the upper edge of the bag, which closes and curls up when the said string is pulled.
  • This string is long enough for the ends to be externally hooked to the bag at a particular fixing point placed on the outside of the bag base.
  • the bag can be carried on the shoulder.
  • the aim of this invention is to create a new bag model, characterized in that the said closing and support string is hooked to the base, in such a way that it can act as a double strap allowing the bag to be placed on the shoulders tike a kind of knapsack.
  • a closing seal is also provided which is automatically closed at the bag's open edges, each time the said string is pulled by the user and under the weight of the full bag itself.
  • the bag is one of the type of shopping bags which .are conventionally manufactured like normal bags, in which the base is obtained by folding a tubular sheet longitudinally, in two different dihedrals transversally opposite each other which both start at the same central plane, and by welding the end of the tubular sheet along a diametrical line.
  • the base comes to an end at a sharp edge and if the bag is empty it has a squashed shape, which when full takes on the form of a parallelepiped with a quadrangular base.
  • this invention requires that a seal be applied at the opening of the bag, which goes over the top of the two opening edges of the bag and clamps them one against the other under pressure each time a string is pulled, the ends of which are knotted externally at the base of the bag at two distinct, well-spaced points, after first being threaded through three pairs of holes made for this very purpose on the abovementioned closing seal and on the two open edges of the bag.
  • the knapsack type bag (1) in its preferred form of embodiment, is made up of a single sheet (2), in plastic or paper material, preferably already tubular, internally provided with a reinforcement sheet (3) at its base, and with a closing seal (4) at the opening which is externally glued to the top edge of one of the sides (la) of the bag (1) and folded over and above the top edge of the other side (lb) beside and opposite the first side.
  • pairs of corresponding through holes are made into which a string (5) is threaded.
  • the ends of this string are knotted at two distinct and well-spaced points at the base of the side (la) at which point two through holes are made which are crossed by the two ends of the string (5). These are then made to pass through corresponding holes provided on the support base (3) and on the sheet (2) which is folded and glued underneath the base (3).
  • the string (5) is also threaded through the closing seal (4), the flap of which has two holes on it, with identical center distance and arrangement to those along the top edges of the sides (la) and (lb) of the bag (1), so that when the string (5) is pulled the closing seal is automatically shut against the outside of the top edge of the side (lb) which is squashed together with the closing seal, along the top edge of side (la).
  • number (6) shows normal support strips which are usually applied along the open edges of the bag so as to make it more difficult for the sheet (2) to be torn where the holes are for the threading through of the string (5).
