Abstract
A composite food storage container combines the advantages of glass and polymer while avoiding their disadvantages. A composite food storage container may include an outer polymer container that is configured to accommodate a glass container within the polymer container. Since the food does not contact the polymer, there are no potential concerns with chemicals leeching into the food. Since the glass is surrounded by the polymer container, the glass is protected from breakage and the composite food storage container does not become too hot to easily and safely handle upon removal from a microwave oven.
Claims23
A food storage container comprising:
- a polymeric outer container defining an inner surface;
- a plurality of shock-absorbing ribs disposed on the inner surface, the plurality of shock-absorbing ribs spaced apart along the inner surface of the polymeric outer container;
- a glass container configured for placement on the plurality of shock-absorbing ribs, the glass container including an upper rim;
- and
- a polymeric cover including at least one sealing lip that sealingly engages the upper rim in an air- and water-tight manner.
A bowl cover comprising:
- a bottom formed of silicone;
- a side wall formed of silicone as one piece with the bottom, the side wall and the bottom configured to receive and encircle an inner bowl formed of glass;
- a plurality of ribs extending from an inside of the side wall in a rotationally symmetric manner, the plurality of ribs configured to contact the inner bowl to insulate and isolate the inner bowl from at least the side wall, wherein the plurality of ribs is flexible so as to be shock absorbent,
- wherein each of the plurality of ribs extends from at least the side wall at a non-perpendicular angle with respect to the side wall.
A bowl cover comprising:
- an inner bowl formed of glass, the inner bowl having an upper rim;
- a bottom formed of silicone;
- a side wall formed of silicone as one piece with the bottom, the side wall and the bottom configured to receive and encircle the inner bowl;
- and
- a polymeric cover including at least one sealing lip that sealingly engages the upper rim in an air- and water-tight manner.
