Definitions

  • An easy opening closure is a metal closure in which an opening may be formed by using one or more fingers and without the requirement for using tools.
  • An easy opening closure comprises a closure having a folding rim to be connected to an open end container, and a 0 circumferential score line provided in the closure and enclosing a removable central closure part.
  • This central closure part is provided with a tab which is connected using a rivet to the central closure part. This tab is used for providing an opening in the easy opening closure 5 by popping, tearing off and subsequently loosing the central closure part along the score line from the remaining part of the closure .
  • this upwardly extending free end of the tab is gripped by one or more fingers and the other part of the central closure is torn loose along the score line.
  • the score opens simultaneously in a clock-wise and anti-clock-wi.se direction of the score line .
  • the final part of the opening procedure is the tearing off the central closure at the diametral position to the pop ignition zone.
  • a metal easy opening closure has a thickness of about 0.17 to 0.30mm. A more specific value of this thickness is dependent on the type of metal of the closure, such as aluminum and tin plate.
  • the so called score residual is generally in the range of 50-90 ⁇ m again dependent on the type of metal used and the content of (pressure in) the container.
  • the score residual is conventionally transversally measured in the score line. In a practical embodiment the score residual resides between score lines formed in both surfaces of the closure. If these score lines are not aligned, then the score residual is measured as the shortest distance between the two score lines.
  • both sides of the easy opening closure is provided with a lacquer having a thickness of about 0.01 mm.
  • This reduction in score residual is maximum at the beginning of the tear ignition zones.
  • This reduction in the score residual may have the form of an abrupt step or may gradually decrease over a part of the pop zone, but reaches the maximum at least at the transition between the pop zone and the adjacent tear ignition zone.
  • This reduction in score residual (t) is relative to the score residual in the pop ignition zone, which is generally having a higher or highest score residual in order to impart the easy opening closure with abuse-proof properties .
  • the score residual in the pop ignition zone is higher than in the remainder of the pop zone. Accordingly, the pop force for the initial popping the central closure part is increased but to a level which is still below the maximum initial tear force.
  • the reduction of the score residual is maximum and amounts 8 ⁇ m in this embodiment of the closure and forms a plateau 23.
  • the score residual t gradually decreases to the plateau 23 in the pop zones (between the respective lines 12 and 14, and 11 and 13) and in the tear ignition zones 15 and 16 gradually increases (curve A) .
  • the reduction of the score residual may stay substantially constant in the tear zones 19 and 20 but decrease gradually towards a hinge zone 21 where the scored central point is broken off from the closure (curve B) .
  • the residual may be increased to about 70 ⁇ m to make the closure more abuse- proof.

Abstract

L'invention concerne une fermeture à ouverture rapide, comprenant un couvercle (1) à bord pliant (2) et une pliure circonférentielle (3) conservant, dans la pliure, un résidu de pliure (t) sur l'épaisseur du couvercle (1), entourant une partie centrale amovible de couvercle (4), et une languette (5) connectée à la partie centrale du couvercle (4), la pliure (3) comportant une zone de tirage dans laquelle la languette (5) permet de tirer une section du couvercle central le long de la pliure, la zone de tirage comprenant une zone d'amorçage de tirage adjacente à la languette, et des zones subséquentes déchirables dans les sens horaire et antihoraire dans lesquelles l'utilisation de la languette (5) provoque le déchirement de la partie centrale du couvercle (4) de la fermeture (1) le long de la pliure (3) avec, éventuellement, l'enlèvement complet de la fermeture (1), les zones de déchirement comprenant une zone d'amorçage de déchirement adjacente à la zone de tirage respective, et le résidu de pliure (t), dans la zone d'amorçage de déchirement, étant réduit par rapport au résidu de pliure dans la zone d'amorçage de tirage. L'invention concerne aussi un contenant équipé d'une telle fermeture à ouverture rapide et un appareil de production de cette fermeture.
