  • Patent number: 4548348
    Abstract: A disposable cup assembly comprising an integral thermoplastic thin-walled liner having a sidewall of truncated substantially right circular conical shape and having a closed bottom wall, for receiving the beverage. The assembly also includes an integral thermoplastic thin-walled holder for receiving the liner with the holder also having a sidewall of substantially truncated right circular conical shape. The liner and holder include releasable interlocking means for retaining a liner in the holder. The sidewall of the liner has a greater angle of convergence with its axis than does the sidewall of the holder, to form a thermally insulative air pocket beneath the level of the interlocking means. Furthermore, the holder is symmetrical about any plane containing its longitudinal axis so that a plurality of the holders substantially fully telescopically nest in a stack.
