Abstract: A doubled-layer disposable cup assembly with air insulation comprises of two layered-cups one inside the other. Each layer has a truncated conical side wall with an outwardly joined rim at the top ends and a bottom wall at the smaller end. The outwardly joined rim of the inner layer maintains an air space between the side walls of the two layers. The contacts at the bottom and top provide support for the inner layer and maintain it in axial alignment with the outer layer. The contact pressure between the rim of the inner layer and the side wall of the outer layer essentially seals the air space for a more efficient air insulation and also provides a force that keeps the inner layer and the outer layer together.
