Definitions

  • the present invention relates to a packaging comprising a container and a lid held on the container by virtue of the pressure difference established between its two faces.
  • the subject of the invention is therefore a package comprising a container whose opening is bordered by an annular wall which has an end surface and a cover maintained in abutment on this end surface of the container thanks to the pressure difference established between its two faces, in which the end surface of the annular wall is striated with concentric grooves.
  • each of the grooves from the inside to the outside of the container, constitutes an intermediate chamber in which the pressure which is established is intermediate between that prevailing outside the container (atmospheric pressure) and that prevailing at the inside the container (partial vacuum).
  • the pressure difference existing at the right of each edge of contact of the container with the sealing material that the cover carries on its inner face is less than the total pressure difference between the interior and the exterior of the container. It follows that at each edge, the seal is better ensured because it is subjected to a lower pressure gradient.
  • the terminal surface of the annular wall is in the form of a truncated cone, the small base of which constitutes the top of this terminal surface.
  • an imbalance of the frictional forces is deliberately created so that the friction between the outer edge close to the large base of the truncated cone is less than the existing friction at the inner edge close to the small base of this trunk of cone. It is then possible by means of the cams provided on the side wall of the container to exert a force on the skirt of the cover tending to slightly deform this cover to create a leak point allowing the entry of air inside the container and the release of friction forces.
  • the packaging of the invention comprises a container 1, for example made of glass, with an upper opening 2 bordered by an annular wall 3.
  • This annular wall has an end surface 4 which has circular grooves 5 (for example two grooves circular defining between them three vertices.)
  • a cover 6 having a skirt 7 can freely cover the end part of the annular wall 3 bordering the opening 2 of the container 1.
  • this cover 6 comprises at the base of its skirt 7, teeth 8 facing inwards which can bear when the cover is rotated relative to the container on cam surfaces 9 in the form of a ramp which protrude from the outer surface of the annular wall 3.
  • the cover 6 has on its internal surface 6a and at near the skirt 7, a layer of a sealing material 10 of the polymer or rubber type by which it rests on the terminal surface 4 of the annular wall 3.
  • the terminal surface 4 is therefore provided with two grooves 5 which define between them three projections of triangular section 11, the top of these projections being in a plane substantially perpendicular to the general axis of the container.
  • the two grooves 5 constitute intermediate chambers in which the prevailing pressure is between the outside and inside pressure of the container.
  • the pressure difference tending to break the seal established at each apex 11 is less than the pressure difference between the interior and the exterior of the container. It follows that at each vertex, the sealing material is less stressed therefore can resist a longer tendency to leak and allow the atmosphere to enter the interior of the container.
  • the variant shown in Figure 3 simply differs from that of Figure 2 in that the terminal surface 4 in which is located each projection 11, is a very flattened truncated cone, the angle at the top may be of the order from 170 to 175 °, the large base of this truncated cone being outside the container and the small base being inside and forming the top of the terminal surface 4.
