CA 2441133

Vacuum lids compatible with containers to preserve food stored in the container. The lid has a top surface with an access aperture, a plurality of raised members of varying heights, and a removable raised member that covers a container valve. A vacuum is applied to the container valve, wherein air from the container is removed form the container. The container is then sealed with a membrane, thereby holding a vacuum inside the container.

L'invention concerne en règle générale des couvercles à vide, et en particulier des couvercles à vide compatibles avec des contenants, qui permettent d'assurer la conservation d'aliments stockés dans ces contenants. Selon une variante, le type de couvercle considéré comprend une surface supérieure à ouverture d'accès, une pluralité d'éléments surélevés de hauteur variable, et un élément surélevé amovible qui recouvre une valve du contenant. Une dépression est appliquée à la valve, ce qui permet d'extraire l'air du contenant. Ensuite, le contenant est fermé hermétiquement avec une membrane qui assure le maintien du vide dans le contenant.
