Definitions

  • the present invention generally relates to vacuum packaging appliances. More particularly, the invention is directed to cages for protecting fragile products when such products are vacuum packaged using vacuum packaging appliances.
  • Vacuum packaging is a process for removing oxygen and other gases from food and other products that deteriorate in the presence gases. For example, food spoilage can occur due to oxidation and valuable manuscripts deteriorate when exposed to air. Thus, vacuum packaging can extend the life of products that deteriorate in the presence gases by removing nearly all of the gases in a sealed container in which such products are stored. However, some products that are fragile in nature may get crushed during the vacuum packaging process if the container in which they are stored is flexible. For example, if berries are to be stored in a flexible storage bag, the compressive forces caused by the differential pressure between the interior and exterior of the flexible storage bag when the flexible storage bag is evacuated of gases is likely to crush the berries.
  • the present invention is illustrated by way of example, and not by way of limitation.
