Definitions

  • the present invention relates to a hollow notch or net product for vacuum packaging, particularly glass or other thermoplastic material.
  • the ring of this product has notches or threads consisting of slender protuberances slightly inclined relative to the horizontal and regularly distributed over the entire periphery.
  • the vacuum capping capsule cooperates with these threads for opening / closing. It comprises at least one seal which, by contact with the hollow product, ensures a tight seal. The seal is then more or less compressed, preferably reversibly, and especially in case of vacuum packaging.
  • the capsule is compressed on the ring.
  • the nets should be positioned sufficiently low and at a certain inclination to the horizontal to allow the capsule to open. This measure is to prevent the capsule, more or less crushed on the ring due to the vacuum, passes under the nets, its opening is then no longer possible.
  • the object of the invention is to develop a net configuration that is particularly suitable for vacuum packaging, certainly eliminating the case of impossibility of opening described above, by breaking the vacuum rapidly.
  • the subject of the invention is a hollow vacuum packaging product, whose ring comprises threads distributed around its periphery, and between which the closure cap enters into engagement with the opening / closing of the hollow product, characterized in that in the vacuum-sealed state of the hollow product, the closure capsule is capable of entering into engagement exclusively in a gap between two consecutive threads, or in several such consecutive intervals, but not in all of them .
  • the opening of the capsule then occurs in the following particular manner. At first, it is rotated along the axis of the ring, lifting it on one side, asymmetrically, so that the vacuum inside the hollow product is broken. Due to this break in the vacuum, the capsule has then tendency, in a second time, to lift - slightly move away from the ring - also on the side that had not already been.
  • the at least one interval in which the closure cap is able to engage in the vacuum-sealed state of the hollow product are
  • the double inclination of the threads as their characteristic of developed - so maximum - length allow to lower the net, so the engagement zone of the capsule, which is sought in the case of vacuum packaging.
  • the developed is defined as the ring angle corresponding to a thread, with the exception of the ends of the latter, called the input and output values of the cutter.
  • the positioning characteristic of the engagement intervals of the capsule of a first - only - side of the mold joint plane is advantageous in that it makes it possible to prevent nets with maximum development from covering one or both of them.
  • mold plane lines of the mold on the ring Indeed, it is known that long threads covering the joint plane of the mold more or less interfere with the demolding of the hollow product.
  • two threads covering the joint plane of the mold - that is to say diametrically opposed - are non-developed maximum - to facilitate the demolding of the hollow product as seen above - and / or double inclination.
  • the latter feature aims at lowering the lower part (engagement of the capsule) of the threads of joint plane, at an intermediate level, higher than that of the threads located on said first side of the joint plane of the mold, but lower than that of the nets located on the other (second) side of the joint plane. This measure is favorable to the entry in progressive engagement of the capsule with the threads of seal plane, then with the nets of the second side thereof, once the vacuum has been broken as explained above.
  • the capsule undergoes a maximum deformation at the beginning of its rotation, then gradually resumes its initial shape, from the moment when the vacuum breaks. This progressive return to the initial form thus passes through the successive stages of engagement with the nets of increasing low levels.
  • the threads located in their entirety on a second side of the joint plane of the mold
  • the invention further relates to a pot, bottle or bottle of thermoplastic material, in accordance with the hollow product described above.
  • This is particularly preferably a glass product, but also plastic.
  • This figure shows the development of a glass pot ring according to the invention.
  • This ring complies with the GME 20-12 standard of the International Technical Center for Bottling and Packaging (C ET IE) relating to a "vacuum lock ring".
  • C ET IE International Technical Center for Bottling and Packaging
  • the nets 4, 8 are demoldable.
  • the threads 5, 6 and 7 are single inclination, developed not maximum (22 °) and not maximum thickness.
  • the capsule is deformed by lifting on the side of these intervals 10, 11 and 12.
  • the vacuum breaks, so that the capsule approaches its original shape by lifting itself elsewhere than the side of the intervals 10, 11 and 12.
  • the capsule is then able to come into contact with the lower part of the threads 4 and 8 then threads 5, 6 and 7, possibly by rotation (unscrewing) of the capsule.
  • the capsule therefore successively enters into the intervals 10, 11 and 12, then 20, 24, then 21, 22 and 23. It finally returns to its original shape.
