Definitions

  • the present invention relates to a two-piece device arranged to ensure the tight sealing of the bottles, jars and other similar containers while allowing, through a degassing vent operating in the manner of a pressure relief valve, the exhaust automatic gas generated by the contents of the container in question.
  • the device according to the invention comprises in the first place a shutter which is capable of engaging in the opening of the container in order to close it in a sealed manner and the central part of which is cut out with an opening bordered by a continuous turned lip to the top.
  • a cape which comprises, in addition to means capable of ensuring its retention on the container and that of the shutter which it covers, a continuous central lip which is turned downwards to cooperate in leaktight manner with the obturator lip, the central part of the bottom of the cape which is subjected to the internal pressure of the container through the opening of the obturator being able to deform elastically to temporarily stop sealing at the two lips in contact, thereby allowing the overpressure gases to escape.
  • the closure device according to the invention as it appears in FIG. 1 comprises firstly a shutter 1 with a circular profile, made of a relatively flexible and deformable synthetic material.
  • This shutter 1 comprises, in the vicinity of its outer edge, a part 10 in the form of an annular bowl open upwards, which is connected on the one hand with an external rim 11 open in the direction of the bottom, on the other hand with a partition annular 12 with frustoconical profile open towards the bottom.
  • This partition 12 is itself joined by an arcuate upper part 13 to a central plate 14 which is integral with a cylindrical lip 15 turned axially upwards. It will be observed that the central plate 14 has a series of openings formed between radial arms 16.
  • the device also comprises a cape 2 in the form of a cover, made of a rigid synthetic material which is capable of deforming elastically only with the application of a relatively large force.
  • the cylindrical skirt of this cape 2 is divided by a thinned annular zone 20 into two superimposed parts.
  • the lower part 21 is intended to form a tear-away guarantee belt and it has an internal retaining bead 22, while the upper part 23 itself has an internal annular projection 24.
  • the upper bottom 25 of the cap is established in a profile very slightly concave open opposite the skirt, and it is integral in its central part with an axial cylindrical lip 26 facing downwards.
  • the lips 15 and 26, intended to cooperate with each other have a straight face and an oblique face.
  • the oblique face, referenced 17, of the lip 15 is arranged inside while the oblique face 27 of the lip 26 is located outside. In addition, these two oblique faces 17 and 27 have slightly different angles.
  • the device thus arranged is intended to close off a glass jar 3, the opening 30 of which is bordered at its top by a rim 31 facing outwards.
  • the shutter 1 is engaged in the opening 30, the bowl 10 coming to closely fit in the upper outlet 32 of said opening while ensuring a tight contact.
  • the rim 11 itself comes to bear against the flat upper face of the rim 31.
  • the bead 22 of the guarantee belt 21 snaps below the rim 31 while ensuring the retention of said cap and of the shutter 1 capped by the latter, it being observed that the free edge of this shutter 1 comes to it -Even clip on above the annular projection 24.
  • the lip 26 of the cap 2 engages by force inside the lip 15 of the shutter which is thus deformed; a tight contact is thus obtained which in a way operates the plugging of the perforated central plate 14 of the shutter.
  • This deformation of the cap 2 causes the sealing of the contact between the two lips 26 and 15 to cease, so that the pressurized gases enclosed in the upper part of the pot 3 can escape to the outside by first passing through the space provided between the two aforementioned lips, then grooves 18, 28 and 29 made for this purpose respectively in the upper face of the annular rim 11 of the shutter 1, in the annular projection 24 and in the retaining bead 22.
  • the guarantee belt 21 which is in no way obligatory, plays the usual role, namely that it guarantees by its presence the original content of the pot 3 until the time of its first use. .
  • this belt 21 has been removed by tearing at the thinned zone 20, the cap 2 is no longer retained on the pot 3, so that it can be removed by the user, it being observed that the shutter 1 is removed at the same time because the clipping of the end edge of the rim 11 above the annular projection 24 ensures the joining of the two parts 1 and 2 of the closure device.
  • this device can be carried out in two successive phases as described above, or in a single phase, the two parts 1 and 2 then being assembled to each other either by clipping above the projection 24, either by simple engagement of the edge of the shutter 1 in the annular housing determined between the bead 22 and said projection 24.
