PACKAGE WITH LID SEALING SYSTEM.

摘要

A package includes a container and a lid adapted to mate with a brim of the container. The lid closes a top opening in the container when mounted on the container. In illustrative embodiments, the lid comprises a membrane sheet and a sheet-support ring coupled permanently to the entire perimeter edge of the membrane sheet. The sheet-support ring is configured to mate temporarily with the brim of the container in any suitable way to retain the membrane sheet in mating and sealing engagement with the container brim so that the opening into the product-storage region formed in the container is closed while the lid remains in place on the container.
