Beverage cup for drinking use in spacecraft or weightless environments

A beverage cup for containing, dispensing, and drinking a beverage in a weightless environment, the beverage cup comprising:

• a closed bottom;
• an open top adjacent a rim, the rim delimiting a size and a shape of the open top corresponding to a size and a shape of the closed bottom;
• a first sidewall;
• a second sidewall coupled to the first sidewall continuously along a common vertical axis and forming an acute angle with a sharp vertex between the first sidewall and the second sidewall, the common vertical axis extending continuously between the closed bottom and the open top;
• a curvilinear rear wall disposed opposite from the common vertical axis and integrally joining the first sidewall and the second sidewall;
• and,
• a cavity defined by a continuous interior surface bounded by the curvilinear rear wall and the open top, the continuous interior surface extending downward from the sharp vertex in a curvilinear direction, the cavity capable of containing and dispensing a beverage disposed in the cavity when the beverage cup is located in a weightless environment, and the continuous interior surface is substantially wetting along the common vertical axis when the beverage is being dispensed by a user in the weightless environment.
