Abstract: The Duo Twin-Containers Drinking Disposable Cup system allows customers to order two different beverages—cold and/or hot—and have them served in two independent and disposable receptacles hosted in a single disposable cup. The twin-containers disposable cup system is comprised of four pieces: two containers in the shape of half cups that neatly fit inside a disposable cup; a disposable cup that hosts the two said half-cup shaped receptacles; and a lid with perforations to allow use of straws or direct lips-to-lid consumption in the case of hot drinks and a diametrical extrusive panel that serves to separate at the top the two half cups to prevent. An empty space between the facing flat sides of the two half-cup-shaped receptacles improves thermal insulation, thus allowing the coexistence of hot and cold beverages without noticeable thermal interference.
