CA 2452312

The invention concerns a separation and/or closure wall designed in the first place, to cover the opening of at least a container to retain a substance contained therein for conservation before use, and subsequently to be torn to reveal said opening and release the substance outside said container for use. Said separation and/or closure wall is characterised in that it consists of a deformable membrane arranged on the periphery of the opening of said container to cover same, with a tension which enables its being burst under the effect of a perforation and/or a tear, to be retracted over the periphery and completely reveal said opening. The invention also concerns methods for assembling two containers containing each a substance partitioned with respect to the other with such a separation and/or closure wall. The invention is applicable to food, pharmaceutical, and dietetic products.

L'invention concerne une paroi de séparation et/ou de fermeture destinée dans un premier temps, à couvrir l'ouverture d'au moins un contenant pour retenir une substance admise à l'intérieur à des fins de conservation avant utilisation, et dans un deuxième temps à être déchirée pour découvrir ladite ouverture et libérer la substance hors dudit contenant à des fins d'utilisation. Cette paroi de séparation et/ou de fermeture est remarquable en ce qu'elle est constituée par une membrane déformable disposée sur le pourtour de l'ouverture dudit contenant pour couvrir cette dernière, avec une tension lui permettant d'éclater sous l'effet d'un parçage et/ou d'un déchirement, pour se rétracter sur le pourtour de ladite ouverture et découvrir entièrement la susdite ouverture. L'invention concerne également des procédés d'assemblage de deux contenants renfermant chacun une substance cloisonnée l'une de l'autre par une telle paroi de séparation et/ou de fermeture.
