The present invention is for a method and cam for folding a tab for removing a seal that has been affixed to a collapsible tube. A laminate removal tab is cut integral with the seal when the seal is cut, and then, in accordance with the present invention, bent back over the neck after the seal is welded to the tube mouth, by means of a cam. The tab is easily lifted and grasped by the fingers to pull the seal off the mouth.
Cette invention concerne une méthode et une came permettant de retirer un dispositif d'étanchéité d'un tube souple en rabattant une languette. Une languette de retrait laminée, découpée à même le dispositif d'étanchéité lors de son découpage, est ensuite replié par en arrière sur le goulot après que le dispositif a été soudé à l'entrée du tube à l'aide d'une came. Il est ainsi facile de soulever et de saisir la languette avec les doigts pour détacher le dispositif d'étanchéité de l'ouverture.
