20080314910 | MULTI-WALL THERMALLY-ISOLATED DISPOSABLE PAPER HOT BEVERAGE CUP - Multi-wall thermally-isolated disposable cups are especially adapted for use as hot beverage cups. A two layer, laminated construction results in a corrugated layer which is fully secured 100% around the circumference of the cup. Enclosed corrugations of a relatively larger size form elongated air pockets running substantially top to bottom of the cup, and provide thermal isolation between the interior contents of the cup and the grasp of a user's hand about the outside of the cup. An outer finished layer or sleeve extends from the rim to the base of the cup. The methodologies and resulting products have improved cup integrity and are relatively cooler to the user's grasp, even with improved heat preservation for the cup's contents, such as hot coffee or other hot beverages. | 12-25-2008 |
