Abstract
A system and method that causes at least one item to be placed within a portion of an elastic film positioned across a top surface of a container, the portion including a center portion in which the at least one item is placed. Air may be extracted from the container to create a vacuum within the cavity and to expand the center portion to create a void in the center portion within the cavity. Air may flow into the container to release the vacuum and contract the center portion of the elastic film as the void is decreased and eliminated.
