Abstract
A capillary beverage cup comprises a continuous interior corner extending from a lip interface into an inner cavity of the capillary beverage cup, the continuous interior corner comprising an acute included angle which tapers continuously as the interior corner approaches the lip interface. The capillary beverage cup provides a continuous capillary force on the liquid contained by the cup, allowing for complete withdrawal of fluid from the cup in low or near zero gravity environments, while enabling the cup to have an open top, allowing for aromatics to be experienced by a user while drinking with reduced concerns of spilling or release free-floating spheres of liquid in the low-gravity environment.
