Title
(DE) SCHRAUBVERSCHLUSS MIT GARANTIEBAND
(EN) SCREW-CONNECTION CLOSURE WITH TAMPERPROOF STRIP
(FR) FERMETURE À VIS MUNIE D'UNE BANDE D'INVIOLABILITÉ
Abstract
(DE)
Bei Schraubverschlüssen (1) mit einem Ausgussstutzen (2), auf den eine Schraubkappe (3) mit einem Garantieband (4) aufgesetzt wird, unterliegen zwischen Garantieband (4) und Schraubkappe (3) vorgesehene Sollbruchstellenbrücken (40) beim Entformen aus der Spritzgussform oder beim axialen Aufsetzen auf den Ausgussstutzen einem vorzeitigen Zerstörungsrisiko. Erfindungsgemäß sind am Ausgussstutzen (2) Pfosten (24) als Rückhalteelemente angeordnet. Sie greifen vor der Erstöffnung in das Garantieband (4) ein. Das Garantieband (4) selbst weist in Bereichen, die beim axialen Aufsetzen von den Pfosten nach außen gedrückt werden, geschwächte Biegezonen (43) auf. Die Sollbruchstellenbrücken (40) sind dort angeordnet, wo während des Aufsetzens und bei der maximalen Verformung des Garantiebandes (4) dieses den unteren Rand der Schraubkappe (3) kreuzt. Das Garantieband kann zusätzlich zu den geschwächten Biegezonen (43) erhöhte Abstützzonen (44) aufweisen, während die dazwischen liegenden Abschnitte (45) eine mittlere Höhe aufweisen.
(EN)
In the case of screw-connection closures (1) with a pouring nozzle (2), on which a screw-connection cap (3) with a tamperproof strip (4) is placed in position, predetermined breaking point bridges (40) provided between the tamperproof strip (4) and screw-connection cap (3) are exposed to the risk of being prematurely destroyed during demoulding from the injection mould or when being placed axially in position on the pouring nozzle. According to the invention, posts (24) are arranged as restraining elements on the pouring nozzle (2). They engage in the tamperproof strip (4) prior to initial opening. The tamperproof strip (4) itself has weakened bending zones (43) in regions which are pushed outwards by the posts when being placed axially in position. The predetermined breaking point bridges (40) are arranged where the tamperproof strip (4) crosses over the lower periphery of the screw-connection cap (3) when it is being placed in position and subjected to maximum deformation. It is possible for the tamperproof strip, in addition to the weakened bending zones (43), to have elevated supporting zones (44), whereas the portions (45) located therebetween are of average height.
(FR)
Dans les fermetures à vis (1) constituées d'un goulot verseur (2) sur lequel est posée une capsule à vis (3) munie d'une bande d'inviolabilité (4), des ponts à points de rupture (40) formés entre la bande d'inviolabilité (4) et la capsule à vis (3) sont exposés à un risque de destruction prématurée lors du démoulage hors du moule à injection ou lors de la pose axiale sur le goulot verseur. Selon l'invention, des tenons (24) faisant office d'éléments de retenue sont agencés sur le goulot verseur (2). Ils s'engagent dans la bande d'inviolabilité (4) avant la première ouverture. La bande d'inviolabilité (4) comporte pour sa part des zones de flexion affaiblies (43) dans des parties qui sont poussées vers l'extérieur par les tenons lors de la pose axiale. Les ponts à points de rupture (40) sont agencés aux endroits où la bande d'inviolabilité (4) croise le bord inférieur de la capsule à vis (3) pendant la pose et lors de la déformation maximale de la bande d'inviolabilité (4). La bande d'inviolabilité peut présenter, outre les zones de flexion affaiblies (43), des zones d'appui plus hautes (44), tandis que les sections (45) se trouvant entre lesdites zones présentent une hauteur moyenne.
