SEPARATION AND/OR CLOSURE WALL FOR A CONTAINER AND METHODS FOR ASSEMBLING CONTAINERS USING SUCH A WALL

摘要

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.
