Definitions

  • the invention relates to a tamper-evident, screw or snap-on stopper, made in a single piece molded from plastic, comprising a tamper-evident ring which keeps the stopper on the neck of the bottle or container to be closed and which is intended to separate from the cap body when opening the bottle or container.
  • the object of the invention is to propose a screw or snap-on plug made of molded plastic which does not have the drawbacks of the plugs mentioned above, which is provided with a tamper-evident ring which is completely molded, which can be easily removed from the mold. without risk of separating the tamper-evident ring from the body of the stopper, which allows it to be mounted on the neck of a conventional bottle, avoiding any crimping or shrinking of part of the stopper under the counter-ring of the neck of the bottle after mounting of the stopper, and which effectively undergoes the separation or the rupture of the tamper-evident ring when uncorking.
  • the tamper-evident ring consists, in accordance with the present invention, of an outer skirt provided with two or more inner segments which are connected to the skirt by their ends oriented with respect to the direction radial at an obliquity in a certain direction so that these segments fold up along the internal surface of the skirt during demolding as well as at the time of mounting the cap on the neck of the bottle or container to then return to their position initial slightly moved away from the skirt of the ring inwards when this ring has crossed the counter-ring of the bottle or container.
  • the inner segments abut on the counter-ring of the container which therefore retains the tamper-evident ring by imposing its separation or rupture at points of least resistance provided for the manufacture of the stopper.
  • the cap is a plastic screw cap for bottles.
  • This stopper molded in one piece, comprises a top 1 from which descends an internal tube 2 intended to penetrate in a leaktight manner inside the bottle neck and a skirt 3 with internal screw threads intended to be screwed onto the thread.
  • outside of the bottle provided above a counter-ring which has a larger outside diameter than the part of the bottle neck situated below this counter-ring.
  • the stopper comprises, at the base of its peripheral skirt 3, a tamper-evident ring composed of an outer skirt 4 and inner segments 5 slightly dear to the skirt 4 to which each of the segments is connected by its two ends 6 oriented obliquely in a certain direction relative to the radial direction as shown in Figures 2 to 4.
  • the skirt 4 of the tamper-evident ring is connected to the base of the skirt 3 of the cap body by a series of narrow bars 7 constituting fasteners of low resistance intended to break when uncorked.
  • the outer profile 8 of the counter-ring of a bottle corked by the stopper shown is shown schematically in dashed lines and it can be seen that the inner segments 5 of the tamper-evident ring came to be placed, at the end of the plug mounting operation, below the base 9 of the counter ring 8. Thanks to the obliquity of the ends 6, the inner segments 5 can fold against the surface internal of the skirt 4 of the tamper-evident ring, facilitating demolding.
  • the inner segments 5 also fold against the skirt 4 of the tamper-evident ring to cross the counter-ring 8, after which they return to their initial position relative to the skirt by placing themselves under the base 9 of the counter-ring as shown in FIG. 1.
  • these segments abut against the shoulder formed by the base 9 of the counter-ring 8, because they cannot fold back because of the obliquity of their ends 6 and the profile of the bottle counter-ring.
  • the unscrewing of the cap exerts on the bars 7 a strong traction causing their rupture and the body of the cap separates from the tamper-evident ring which remains on the bottle.
  • a resistant connection can be provided between the skirts 3 and 4, even on their entire periphery, while points of low resistance are provided at 12 at each of the ends 6 of the interior segments 5, as shown in FIG. 4.
  • the segments 5 then separate from the skirt 4 of the ring by breaking the points 12, while the skirt 4 of the ring remains integral with the body of the stopper and emerges from the neck of the bottle, this ring being provided outside the profile of the neck of the bottle.
  • openings can be used to control the presence of intact parts of low resistance.
