Abstract: Disposable dishware and cookware may be constructed from corrugated paperboard. The corrugated paperboard provides voids filled with air to serve as a natural insulation barrier. In so doing the contents held by the dishware are maintained at a desired temperature longer without transferring temperature to the user. The voids may also serve as conduits or plenums to communicate hot air away from the cookware and thus provide for use at elevated temperatures.

Abstract: A highly adaptable beverage container insulator is designed for a significant size range of beverage containers. The insulator is tubular with open ends that are formed from two elastic panels. Each panel has straight top and bottom edges with elastic hems. The side edges of each panel are slightly curved to maintain the properties and proper appearance of the insulator. To form the insulator, two of the panels are joined along their side edges to form a tube. The insulator is placed around a beverage container to better insulate the container and maintain the temperature of the beverage located therein. The insulator accommodates significant variation in the size and shape of beverage containers. For example, a smaller version of the insulator is readily adaptable to conform to both a standard twelve ounce soda can and to a ten ounce juice bottle.

At least one additional array of reticulated radially inwardly extending projections are provided, and positioned between mutually adjacent pairs of rib arrays, with these projections being segmented to define circumferentially extending land areas between mutually adjacent segments of projections so as to permit the sleeve to engage a variety of conventional cup sizes, and also to provide space for advertising or instructive indicia. Engageable couplings are provided to convert the elongated sleeve to a frusto-conical configuration.

Abstract: Insulating paper container including an inner paper cup and an outer paper cup. The inner cup includes a base and double bulge rings and the inner side of outer cup is coated evenly with chemical laminating agent and foaming agent.

The two bulge rings stabilize the structure of the outer cup hence to form a complete insulating paper container unit, and provide a foam insulating layer between the inner and outer cups by heat activating the chemical laminating agent and foaming agent. Therefore the present invention offers a safe and insulated insulating paper container.
