Abstract
The present invention provides an apparatus for storing and preserving food products and for selectively dispensing the food products from the apparatus, wherein the apparatus comprises a container, a flexible bag inserted into and suspended in the interior of the container, and a cover member releasably securable over a top opening of the container. The bag is provided with a sidewall dimensioned to slide vertically through the interior of the container without the sidewall exerting a friction force against the inner surfaces of the container sidewalls with the bag filled with a food product. The bag is constructed of a flexible material that enables a top portion of the bag sidewall to be stretched and folded back over the top opening of the container and the outer surfaces of the container sidewalls to suspend the food product contained in the bag inside the container interior and above the container bottom wall. By selectively sliding the folded over portion of the bag vertically downward and upward over the exterior surface of the container sidewalls, the food product contained inside the bag and suspended in the container interior is raised up in the container to the top open…
