Abstract:
A container for product storage including an expandable portion is provided to eliminate space between the container and the product to prolong the remaining products usable life within the container after opening. The invention includes a storage container () that has a cover () and product () within its interior. An inflatable bladder () is disposed within the storage container and a tube () penetrates through the container and is connected to the bladder. A valve () is attached to the tube's distal end and a pressure source, which could include heat or cooling, is connectable to the valve. The combination of the valve and the pressure source supplies the required pressure to inflate the bladder () which occupies the space between the product within the storage container () and the cover () thereby precluding ambient atmospheric contact with the product. A releasable pressure valve () is provided to discharge pressure created within the container when the bladder is inflated.
