Definitions

  • the invention relates to a closure device made of plastic material for bottles and other containers for liquids, in particular gaseous liquids, equipped with a neck comprising an upper crown constituting a bead projecting outwards, the device comprising a cylindrical cap, integral a guarantee strip, and provided with a rim projecting inwards and intended to ensure the maintenance in position of the device by snap-fastening of said rim under said bead, and a lateral appendage intended to be actuated for uncorking the container .
  • Plastic safety caps for bottles are already known, provided with a guarantee strip.
  • the most common are of the screw type, with a security strip shaped so as to be held in position under the lower part of the spout, which requires a relatively large plug height.
  • Caps are also known of the capsule type provided with a lateral actuating appendage, comprising a guarantee strip, and which are removed by exerting a force from the bottom up on the appendix using the thumb that the one engages under the appendix.
  • these plugs are of a relatively complicated design and the guarantee strip badly fulfills its security role when it does not include means intended to keep it in position under the lower part of the spout, the latter condition implying a significant capsule height. .
  • the object of the present invention is to provide a plastic-type safety cap of the capsule type provided with a lateral actuating appendage and an effective safety strip, of reduced height, simple to produce and inexpensive and which allows to remedy the drawbacks mentioned above.
  • the invention relates to a closure device made of plastic material for bottles and other containers for liquids, as defined in claim 1.
  • the device of the invention thanks to the conformation of its actuating appendage allows a smooth opening of the bottles containing gaseous liquids which may be under high pressure.
  • the pressure of the thumb engaged under the appendix initially involves a horizontal force exerted radially towards the exterior, causing the separation of said appendage relative to the guarantee strip and the initiation of the rupture of the line of least resistance between the guarantee strip and the cap. This separation and this initiation of rupture having taken place, it is then easier to measure the force for the opening of the bottle, in particular to prevent a spouting of the liquid when it is under high pressure inside the bottle. .
  • the device comprises a cylindrical cap 1 comprising a head part 2 and a cylindrical peripheral part 3.
  • the head part is provided with an internal sealing joint 4 known per se.
  • the peripheral part of the cape has a rim 5 projecting inwardly and intended to ensure the holding the cap on the bottle 9 (FIG. 3) by snapping on said rim 5 under the bead 6 formed by the upper crown 7 of the neck 8 of the bottle.
  • the cap also comprises a guarantee strip 10 connected to the lower edge of the peripheral part 3 of the cap by a line of least resistance 11, and a lateral appendage 12 intended to be actuated for uncorking the bottle.
  • the appendix 12 can be produced in the form of a parallelepiped body as shown in FIG. 4. It can include a central rib 13 as shown in FIG. 2.
  • the appendix is made integral at its upper part with the lower edge of the peripheral part 3 of the cape via a substantially horizontal connecting part 15. It is also connected laterally to the guarantee strip 10 by two lines of least resistance 14, 14 '.
  • This appendage is arranged entirely offset on the outside of the cape, so that the uncorking of the bottle is necessarily carried out in two stages, a pressure of the thumb engaged under the appendage having the effect of pivoting the appendage towards the high around the connecting part 15.
  • the pressure of the thumb engaged under the appendage results in a force which has a horizontal component which is exerted radially outwardly and which, firstly, leads to the rupture of the lines of least resistance 14, 14 ′ connecting the appendix to the guarantee strip and, on the other hand, the initiation of line rupture of least resistance 11 between the guarantee strip and the cape.
  • the cap is then reusable to recap the bottle.
