Definitions

  • the closure shell and/or the roof is removable.
  • the bridges form a weakness line and are tom apart from the closure shell and/or the roof, so it is separated from the bottle.
  • the weakness line is tom when user unscrews the closure shell of the stopper or when user lifts the roof by tilting.
  • a solution consists in linking the closure shell to the tamper band secured on the bottle neck, so the closure shell stays attached to the bottle after bottle opening.
  • Such an attached stopper is so called a “tethered stopper”.
  • An object of the present invention is to improve a tethered plastic screw stopper wherein its closure shell remains attached to its tamper band after bottle opening through at least one strip, especially two strips, made into the plastic material of the stopper between the tamper band and the closure shell through a bottom weakness line and a top weakness line.
  • Each strip remains connected to the tamper band secured on the bottle neck through a least a bottom hinge positioned approximately into the bottom weakness line.
  • the opposite ends of the strip are directly linked to the closure shell through junction points.
  • the stopper according to the invention comprises a specific top weakness line, with at least one top bridge located over each strip and over a bottom bridge of the bottom weakness line located at the nearest from the bottom hinge(s), so called “nearest bottom bridge”.
  • FIG. 2 is a diagrammatic lateral view similar to FIG 1, during a first step of opening of the stopper;
  • the invention relates to a tethered plastic screw stopper 1, for closing a bottle neck 2.
  • the stopper 1 is integrally made of one plastic piece by a molding fabrication step. Other parts or elements of the stopper 1 can be further created into the entire plastic piece through a cutting or slitting step.
  • the stopper 1 comprises a closure shell 4 and underneath a tamper band 6.
  • the tamper band 6 and the closure shell 4 are separably linked together.
  • the bottom weakness line 12 also comprises bottom bridges 120 to be stretched and broken when unscrewing the closure shell 4.
  • the bottom bridges 120 are regularly or not positioned approximately around the bottom weakness line 12, so around the stopper 1 exception of the length of the hinge(s) 14.
  • the closure shell 4 comprises inner threads to be screwed and unscrewed on the bottle neck 2.
  • only one of the top bridges 100 which is located at the nearest from the junction point at the opposite side relative to the screwing direction of the closure shell 4, so in the unscrewing direction.
  • Such only one of the top bridges is positioned approximately over the bottom bridges located at the nearest from the hinge 14 in the side relative to the screwing direction.
  • the only one of the top bridges 100 is located at the nearest from the junction point on its right side, where the bottom bridge is located at the nearest from the hinge 14 on its left side.

Abstract

L'invention comprend un bouchon à vis en plastique attaché comprenant une coque de fermeture et une bague d'inviolabilité. Au moins une bande est reliée de manière séparable à la coque de fermeture, par l'intermédiaire d'une ligne de faiblesse supérieure, et la bague d'inviolabilité, à travers une ligne de faiblesse inférieure. La ligne de faiblesse inférieure comprend au moins une charnière reliant la déchirure et la bague d'inviolabilité. Chaque bande comprend une extrémité à une extrémité de la ligne de faiblesse supérieure, reliant la bande à la coque de fermeture au niveau d'un point de jonction. La ligne de faiblesse supérieure comprend des ponts supérieurs et la ligne de faiblesse inférieure comprend des ponts inférieurs, et les ponts sont destinés à être étirés et brisés lors du dévissage de la coque de fermeture. Au moins un des ponts supérieurs est situé au niveau le plus proche du point de jonction, est positionné approximativement sur au moins l'un des ponts inférieurs situés au niveau le plus proche de la charnière.
