Definitions

  • the present invention relates to a continuous band, which has been especially designed for the manufacturing of bags for fruit and vegetable products and the like, by longitudinal heat-sealing of said band through its longitudinal edges, to turn it into a continuous tube, and by transversal cutting and sealing parallel to said cut, for the production of the unitary bags, closing and making independent thereof.
  • the object of the invention is to achieve a continuous band which incorporates two rectangular plates of plastic material and a series of windows and, where applicable, perforations, wherefrom it is possible to obtain, by the joining of its edges by heat-sealing, a bag, two of the sides whereof are rigid, and which adopts a form similar to a tray or basket once filled with the product to be packed and which has one or more perforations, in order to obtain maximum mechanical resistance of the bag, a correct aeration of the products, an optimum protection of the products contained therein against squashing, a greater capacity for printing on the bag and faster manufacturing speed of the bag and in its filling.
  • Certain fruit and vegetable products such as tomatoes, cherries, oranges, etc. have been sold for a long time in paper or cardboard baskets or wooden or plastic boxes which, in many cases, are protected and wrapped in perforated or non-perforated plastic bags which allow aeration of the product, direct display of the product, its protection against squashing and facilitate their storage or display in the display stand and shelves of the point-of-sale.
  • Said baskets or boxes have to be filled with said products manually or by machines with low manufacturing speeds. Furthermore, these baskets or boxes have to be wrapped in plastic bags. The packaging process of the fruit and vegetable products in said baskets or boxes is slow and the materials have a high cost.
  • the continuous band for the manufacturing of bags proposed by the invention is a novel technological advance in this field and is based on the use of a continuous band which is designed to be closed over itself, by the joining of its longitudinal edges by a heat-seal parallel to said longitudinal edges, to configure a continuous tube that can be fragmented in a plurality of sectors corresponding to the respective bags, said continuous band has one or more windows and, where applicable, perforations of the same or a different size.
  • Said continuous band is a continuous plastic sheet, of a width equal to that of the continuous band. Two rectangular plates of plastic material are joined to said continuous plastic sheet in correspondence with each one of the sectors of the continuous plastic sheet provided for the production of a bag, the longitudinal axes of which are parallel to the longitudinal axis of the continuous plastic sheet.
  • the distance between the longitudinal axes of the two rectangular plastic plates is half the width of the continuous plastic sheet.
  • the length of the rectangular plastic plates is less than the length of the sectors provided for the production of a bag minus the width of said rectangular plates.
  • the rectangular plastic plates are joined to the continuous plastic sheet by heat-sealing or gluing.
  • the material of the rectangular plastic plates may be polypropylene or polystyrene.
  • each one of the sectors of the continuous plastic sheet it is possible to establish at least one window, which is closed with the collaboration of a fragment of net, formally and dimensionally adapted to said window and fixed by heat-sealing to the periphery of said windows, such that the windows does not overlap with the rectangular plastic plates.
  • the net which closes the window may be a continuous strip of net which runs longitudinally along the continuous plastic sheet.
  • the continuous band [1] for the manufacturing of bags object of the present invention, comprises a continuous plastic sheet (2), with a width coinciding with that of the continuous band (1) and consequently of a width greater than double the width of the bag to be produced.
  • Groupings of windows (3) and, where applicable, perforations (10) both produced by die-cutting, are established along the continuous plastic sheet (2) and positions (4) of the rectangular plastic plates (5), preferably one grouping for each bag (7) to be produced from said continuous band; there is at least one window (3) centred on what must be the upper face of the bag, and optionally a series of perforations (10) which, without the need for them to be closed by fragments of net, collaborate in the aeration of the product packed.
  • the position of the rectangular plastic plates (5) of each grouping shall be suitable so that on manufacturing the bag they are placed on the sides of the bag where there is no heat-seal.
  • the continuous plastic sheet (1) shall be joined by its longitudinal edges by a longitudinal heat-seal (8) and by a double line of transversal heat-seal (9) to form the bag.
  • the rectangular plastic plates can be fixed to the continuous plastic sheet by the heat-sealing of its edges to the continuous plastic sheet or by gluing.
  • the windows are closed by a strip of net (11) which runs longitudinally along the plastic sheet and which is fixed to said sheet by transversal heat-seals (9).
  • the resulting bag once filled with the chosen fruit or vegetable product, adopts a form of tray or basket wherein two of its sides are formed by two rectangular plastic plates (4), the material of which may be polypropylene or polystyrene, which offer optimum resistance to prevent the squashing of the packed product.
  • the resulting bags offer large areas for graphic printing alluding to the products contained therein.
