A cup can include a base and a sidewall extending upward from the base to a top of the cup. The sidewall can taper at an angle between 4 and 12 from the base. The sidewall can include an upper sidewall and a lower sidewall. The lower sidewall can include a first portion, a second portion, and a third portion. The lower sidewall can include a plurality of channels arranged around an outer circumference of the lower sidewall. In the first portion, the plurality of channels can have a first width between 0.05 inches and 0.065 inches and a first depth between 0.05 inches and 0.065 inches. In the third portion, the plurality of channels or grooves can have a second width between 0.02 inches and 0.035 inches and a second depth between 0.02 inches and 0.035 inches.

A portable beverage container capable of autonomously generating ice using an internal cooling system. The cup includes a thermoelectric cooling mechanism within a lower chamber that transforms water into ice. An optional embodiment allows the user to pour or store beverages in the same unit, enabling ice to cool the liquid directly for drinking. The invention is compact, self-contained, and ideal for travel, outdoor use, or situations where conventional refrigeration is unavailable.

A container assembly for storing multiple liquids is disclosed. The container assembly comprises a container body having a first compartment and a second compartment. Each compartment comprises an upper end, an opening at the upper end, and a lower end. The container assembly further comprises an insulator provided between the first compartment and the second compartment configured to separate both compartments, thereby allowing the container body to store multiple liquids simultaneously. Further, the container assembly further comprises a rotatable lid detachably attached to the upper end of the container body configured to prevent and stop any leakage, wherein the rotatable lid is activated to set the amount of liquid to be dispensed from each compartment.
