Definitions

  • the invention relates to a new type of secondary seal intended to be inserted at the bottom of a cap or a capsule.
  • the secondary seals consist of polypropylene (PP) or polyethylene (PE) foams, optionally laminated with PP, PE or polyethylene terephthalate (PET) films.
  • PP polypropylene
  • PE polyethylene
  • PET polyethylene terephthalate
  • JP2006 / 123970 discloses secondary seals having a high rockwell hardness, of the order of 110. These seals are formed of a PET foam laminated on each of its faces with a polymer film made of PE. If the rigidity is improved, there is still a barrier to oxygen and resistance to temperature still insufficient.
  • US 3,213,743 discloses a seal associating two layers of polymer of distinct density to be inserted into the peripheral groove of a lid. It is not a secondary seal within the meaning of the invention.
  • US-A-4,699,286 discloses a gasket made of polystyrene foam.
  • the problem that the invention proposes to solve is to develop secondary seals fulfilling at least the 3 criteria that are: oxygen barrier, aroma, odor, temperature resistance, rigidity.
  • a single polyester foam advantageously PET as a secondary seal, made it possible to solve all of these problems simultaneously.
  • a single PET foam gives better results in terms of oxygen barrier, temperature resistance and rigidity than the PET-PE film complex as described in the prior art.
  • the subject of the invention is therefore a secondary seal intended to be inserted at the bottom of a cap or of a capsule constituted by a support made of an expanded material, which is characterized in that said material is a polyester foam, advantageously polyethylene terephthalate (PET).
  • PET polyethylene terephthalate
  • the seal may have on at least one of its faces a polymer film, with the exception of PE.
  • the polyester foam advantageously PET has a density between 30 and 500 kg / m 2 , preferably between 100 and 300 kg / m 3, that is to say a mean density.
  • the thickness of the polyester foam is between 0.6 mm and 2 mm.
  • the polyester foam advantageously PET constituting the secondary seal of the invention has on at least one of its faces, preferably the face opposite the bottom of the plug or the capsule, a PET film.
  • the PET film can be coextruded or calendered.
  • the PET film has a thickness of between 5 ⁇ m and 100 ⁇ m, preferably between 10 and 30 ⁇ m.
  • the polyester foam advantageously PET is coated on at least one of its faces with a polypropylene film, applied by gluing.
  • a polypropylene film applied by gluing.
  • the glue used is a two component isocyanate - hydroxide glue.
  • the polyester foam is a polylactic acid foam or PETG foam (for example copolyester of terephthalic acid with a mixture of ethylene glycol and another diol such as cyclohexanedimethanol).
  • the shape of the secondary seals of the invention will be determined according to the shape of the plug or the capsule.
  • Figure 1 is a sectional diagram of the secondary seal of the invention in its simplest form.
  • Figure 2 is a sectional view of a second embodiment of a secondary seal of the invention.
  • the secondary seal of the invention designated by the general reference 1 consists of a simple PET foam (2).
  • the foam has a thickness of 1 mm and a density of 200 kg / m 3 .
  • FIG. 2 is a representation of a second embodiment.
  • the seal (1) consists of a PET foam (2) having the same characteristics as above, covered on both sides, with a PET film (3, 4) applied by coextrusion.
  • the PET film has a thickness of 25 microns.
