Definitions

  • the present invention relates to packaging comprising a container and a lid held on the container thanks to the pressure difference established between its two faces.
  • the invention therefore relates to a packaging comprising a container whose opening is bordered by an annular wall which has a surface terminal and a cover kept pressed on this container end surface thanks to the difference of pressure 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 towards the outside of the container constitutes a chamber intermediate in which the pressure which is established is intermediate between that prevailing outside the container (atmospheric pressure) and that prevailing at inside the container (partial vacuum).
  • the terminal surface of the annular wall is in the form of a truncated cone, the small base of which forms the vertex of this terminal surface.
  • we voluntarily creates an imbalance of the friction forces so that the friction between the outer edge neighbor of the large base of the truncated cone is less important than the existing friction at the edge interior near the small base of this truncated cone. It is then possible by means of the cams provided on the side wall of the container to exert an effort on the skirt of the cover tending to slightly deform this cover to create a vanishing point allowing air to enter inside the container and the release of forces from friction.
  • the packaging of the invention comprises a container 1 for example made of glass with a upper opening 2 bordered by an annular wall 3.
  • This annular wall has a terminal surface 4 which has circular grooves 5 (for example two circular grooves defining between them three vertices.)
  • a cover 6 having a skirt 7 can come freely cover the terminal 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 inward which can be supported when you rotate the cover relative to container on cam surfaces 9 ramp-shaped protruding from the surface outside of the annular wall 3.
  • the cover 6 has on its internal surface 6a and at near the skirt 7, a layer of sealing material 10 of the polymer or rubber kind 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 apex 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 external and internal pressure of the container.
  • the difference pressure tending to break the seal established at each vertex 11 is less than the pressure difference between the inside and the outside of the container. It follows that at each vertex, the sealing material 10 is less stressed therefore can resist a longer tendency to flee and let the atmosphere inside of the container.
  • FIG. 3 differs simply that of FIG. 2 by the fact that the terminal surface 4 in which each projection is located 11, is the lateral surface of a trunk of cone very flattened, the angle at the top can be of the order of 170 to 175 °, the large base of this truncated cone being on the outside of the container and the small base being inside and forming the top of the surface 4.
