Definitions

  • the present invention relates to the field of packaging, in particular tubular packaging, and relates to a method of manufacturing a body of a tubular packaging comprising at least two superimposed layers of a material such as paper, cardboard, metal foil. , synthetic material, or any other material, a packaging thus obtained and a device for implementing this process.
  • a material such as paper, cardboard, metal foil. , synthetic material, or any other material
  • connection of these different layers is ensured by sealing or gluing.
  • the bottoms or covers of these packages are composed either of a completely different structure from the body, or of a structure equivalent to that of the body.
  • they may advantageously be composed, from the inside of the packaging towards the outside, by a complex identical to that internal to the body and in contact with the product to be packaged, by one or more sheets of a material.
  • more rigid than the complex such as corrugated paper, cardboard, wood, metal, synthetic material, expanded polystyrene or any other material, the number of sheets to be applied being a function of the rigidity of the bottom or of the cover the packaging to be obtained, and optionally by a layer or an external complex, whether or not printed.
  • Such a structure is described in French patent application No. 8701510.
  • the bodies of tubular packaging are normally manufactured in the following manner: the different strips are unwound on a reel, the width of each strip corresponding to the width of the profile to be produced, the width of each is increased next strip of the thickness of the previous strip, each strip is shifted laterally, the strips are assembled together to form the profile, the profile is folded so as to first form an open U, then a closed U , then an O, the joints, combined with the offset of the bands, thus also being offset, then the profile is dried and finally the cut is carried out, generally by means of circular knives guided by a format cam, profile thus obtained in different sections, the length of which corresponds to that desired of the packaging body, and the bodies thus obtained are removed.
  • a format cam profile thus obtained in different sections, the length of which corresponds to that desired of the packaging body, and the bodies thus obtained are removed.
  • the packaging body obtained by application of such a method has the major characteristic of being provided with a weakening zone at the location of the various overlaps of the bands. It follows that the packaging body is not statically balanced. This static imbalance leads to various drawbacks, both at the level of the manufacturing process and at the level of the packaging body itself.
  • the static imbalance leads to difficulties in positioning and crimping the bottom and the cover.
  • the interior complex is very difficult to set up by heat sealing, due to the overlap of the different strips, the latter resulting in particular in a lack of space for the heat sealing tool; therefore either the production rates are slowed down, or the interior complex is abandoned, which of course greatly affects the sealing of the packaging body.
  • GB-A-2 000 105 discloses a multi-layer packaging box, as well as its manufacturing process.
  • the aforementioned method consists in producing the side walls of said box by the superposition by gluing of a plurality of layers each formed by strips of flexible material juxtaposed transversely.
  • document DE-B-1 227 772 also discloses a method for manufacturing a tubular packaging body, in particular a multilayer paper bag, comprising an internal complex and at least two superposed layers formed around said internal complex and made of a material such as paper, said method consisting in unrolling, first of all, a strip intended to constitute, after heat sealing, the sealed internal complex compatible with the product to be packaged, of the body to be produced.
  • This document also describes a device for implementing the aforementioned method, consisting of a continuous forming machine for the tubular packaging body, connected, on the one hand, to at least one reel, if necessary gluing, to the number of one per layer of the packaging body and, on the other hand, to a reel of the strip intended to form the internal complex of said packaging ccrps.
  • this tubular body is not joined together and are each made up of a single strip of paper, respectively of waterproof complex, the lateral edges of which are folded back and assembled at the edge by mutual overlap and against bonding, so as to constitute a tubular body provided with a longitudinal allowance and having not undergone any particular shaping operation.
  • the different joining and overlapping areas of the different layers are not offset between them for two successive layers, which causes a structural imbalance of said packaging body, as already mentioned above.
  • the general problem to be solved by the object of the present invention therefore consists in designing, starting from document DE-B-1 227 772, a manufacturing process and a device for its implementation, making it possible to obtain a perfectly sealed, balanced packaging body, without causing deformations due to internal stresses, in particular by eliminating all weakened generators and all excess thicknesses due to overlapping of the bands and by joining the different layers together.
  • This process should also allow a significant rate of manufacture of the packaging bodies, an easy longitudinal heat-sealing of the interior complex as well as an equally easy installation of the bottoms and covers.
  • this general problem is solved in that it relates to a method of manufacturing a body of a tubular package according to the preamble of claim 1, characterized in that it consists, all first, to shape and put in place, by continuous heat sealing, the sealed internal complex, the latter being composed either of a strip folded over on one side and heat sealed on each side, or of two strips which are heat sealed on each side , then to unroll at least two strips intended to form the constituent parts of the first layer of the body to be produced, to shape them and put them in place, by gluing or heat-sealing on the internal complex, in such a way that they are contiguous, without overlapping, the sum of the width of each strip corresponding to the perimeter of a packaging body, then unrolling at least two strips intended to form the constituent parts of the second layer of the co rps to be produced, shaped and put in place by gluing or heat sealing on the first layer so that they are also contiguous without overlapping, but the joints of the bands forming the constituent
