CA 2680274

A container or array of containers that is are sealed with a peelable seal is transported via a conveyor along a processing path toward a desealing station at which an adhesive surface having a width substantially the same as or greater than the width of the seal is pressed against the upper surface of the peelable seal. A collection rod applies a downward pressure on the adhesive surface, pressing it against the seal and keeping the container or container array in position on the conveyor as the plate moves with the conveyor. As the leading edge of the seal passes the collection rod, the adhesive surface is rolled upward, away from the plane of the seal, pulling up on the leading edge of the seal to separate it from the container or container array while the container or container array is held down by the roller. The removed seal is then discarded.

L'invention concerne un contenant ou un ensemble de contenants fermé à l'aide d'une pellicule de fermeture transportés par le biais d'un convoyeur le long d'un trajet de traitement vers un poste de déscellage au niveau duquel une surface adhésive ayant une largeur sensiblement égale ou supérieure à la largeur de la pellicule est pressée contre la surface supérieure de la pellicule de fermeture. Une tige de prélèvement applique une pression vers le bas sur la surface adhésive, la pressant contre la pellicule et maintenant le contenant ou ensemble de contenants en position sur le convoyeur à mesure que la plaque se déplace avec le convoyeur. Lorsque le bord d'attaque de la pellicule passe au-delà de la tige de prélèvement, la surface adhésive est enroulée vers le haut et éloignée du plan de la pellicule, tirant sur le bord d'attaque de la pellicule pour le séparer du contenant ou de l'ensemble de contenants alors que le contenant ou l'ensemble de contenants est maintenu en bas par le rouleau. La pellicule retirée est alors mise au rebut.
