Abstract
The cover of the inside container is firmly fixed on the sides of the exterior container. When the empty space between both containers is filled-up with any type of freezing liquid, an ice layer is created and preserves everything in the inside container for an unlimited period of time. A plastic membrane is inserted into a groove all around the inside portion of the external container. The liquid infiltrates in the groove above the membrane and when placed into a freezer nothing could affect or infect what is underneath the ice sealant.
