ABSTRACT:
A convertible cup, connectable to a vacuum bottle, is provided including a dome-shaped cover part and a cup-shaped vessel part. The dome-shaped cover part has first threads, a first opening for the dispensing of liquids, and a second opening for the intake of air. A cup-shaped vessel part has second threads suitable for connection to the first threads. When the second threads are connected to the first threads, the cup-shaped vessel part may be nested inside the dome-shaped cover part thereby forming a cup with an open top. The cup-shaped vessel part also has third threads suitable for connecting to the first threads. When the third threads are connected to the first threads, the cup-shaped vessel part and the dome-shaped cover part form a chamber. The convertible cup may also include fourth threads on the dome-shaped vessel part for connecting to a vacuum bottle. Furthermore, the dome-shaped vessel part has a base sized to fit into a cup holder when the cup-shaped vessel part is connected to the dome-shaped cover part to form a chamber.
