  • Patent number: 4136800
    Abstract: An edible, stackable cone having a sanitary covering, and a method of vending such edible cones are provided. Each cone includes an inedible, non-toxic sanitary covering disposed over the bottom of the cone and extending upwardly at least a grasping distance, but terminating short of the open cone top. The covered cones are disposed in a nested stack, one above the other, and are automatically dispensed one at a time from the stack to a product-filling area. The covering may be a no-migration plastic, or food-grade paper, or aluminum foil, and the covering may be snugly - but readily removably - adhered to the cone by deforming selected areas of the covering into intimate contact with corresponding areas of the cone, or by providing an interference fit facilitated by ribbing.
