Definitions

  • the present invention relates to a method of producing multilayer objects by compression molding a multilayer dose.
  • US Pat. No. 4,876,052 describes a multilayer object (FIG. 1) characterized in that a first synthetic resin 3 is completely trapped inside a second synthetic resin 2. This multilayer object is obtained by compression molding of a composite dose in which the first resin is totally trapped in the second resin.
  • the multilayer structure described in US Pat. No. 4,876,052 is particularly useful for objects such as containers or lids.
  • the objects obtained according to the method described in US Pat. No. 4,876,052 require a large proportion of functional resin in the object; which generates two major disadvantages; the former being a prohibitive cost and the second a resistance to mechanical stress diminished.
  • Japanese Patent JP 2098415 proposes to produce a multilayer object by compression molding. starting from a composite dose characterized in that the second synthetic resin covers only the lateral faces of the first synthetic resin.
  • the compression molding of this dose along its axis of symmetry leads to an object having a multilayer structure (FIG. 2) characterized in that a first resin 2 partially traps a second resin 3.
  • the multilayer objects made from two resins according to patent JP 2098415 have two major disadvantages; the first being to have the barrier resin 3 exposed in the central surface of the object on at least 10% of the total surface of the object; and the second being to require an amount of barrier resin 7 in the subject of at least 30% of the total amount of resin.
  • Another disadvantage of patent JP 2098415 resides in the fact that the respective quantity of resins 2 and 3 can only be slightly adjusted, these quantities being fixed by the geometry of the object and the flows during compression of the dose. .
  • This dose consists of a first resin 4 forming the central part of the dose, a second resin 3 covering only the lateral faces of the first resin, and a third resin 2 covering only the lateral faces of the second resin .
  • the crushing of this composite dose along its axis of symmetry leads to a multilayer object ( Figure 3).
  • the use of a tri-layer dose has the advantage of reducing the amount of functional resin 3 used and leads to objects having slightly modified mechanical properties compared to the same object comprising a single resin 2.
  • the second resin 3 does not cover the central part of the multilayer object which leads to multilayer objects without barrier property close to the axis of symmetry.
  • the patent application CH01619 / 04 describes multilayer objects (FIG. 4) made from a multilayer dose molded by compression.
  • the objects described in this patent application have a multilayer structure characterized by the position of the functional layer forming a double zigzag-shaped fold. The functional layer is correctly distributed throughout the object, even in the central part.
  • the method for producing multilayer objects described in the patent application CH01619 / 04 also makes it possible to control the thickness of the functional layer.
  • An adhesive layer may be added between the resin forming the surface of the object and the functional resin.
  • the compression of the dose requires a method and a specific molding device. This method requires in particular additional tooling movements compared to the basic compression process setting relative movement of the two parts of the mold. In the case of high speed molding, it may be disadvantageous to use a compression device as described in the patent application CH01619 / 04.
  • Patent EP926078 describes obtaining a cork liner (FIG. 5) by compression molding a dose comprising a lamellar multilayer structure.
  • the functional resin 3 forms lamellae dispersed in the resin 2.
  • the method consists of extruding a lamellar dose (sort of millefeuille) with a device for generating lamellae, then compressing the dose in order to form the liner.
  • a lamellar dose sort of millefeuille
  • This method consists in compression molding a lamellar alloy; the number of lamellae in the dose being very large.
  • This method has the disadvantage of requiring a percentage of high barrier resin (of the order of 20%) to significantly reduce the permeability of the object because the lamellae do not form a continuous layer.
  • Another disadvantage of patent EP926078 lies in the fact that the position of the lamellae in the object can not be controlled. As a result, the resin forming the surface layer of the multilayer object is a mixture of the different layers forming the dose. This may limit the use of the objects described in EP926078 for hygiene reasons when the packaged product is in contact with the lamellar multilayer object.
