Claims19
A cup comprising
- a base;
- an inner wall, defining together with the base a recess for holding a beverage;
- an outer wall connected to the inner wall, defining together with the inner wall a cavity, the cavity partially filled with liquid fluid surmounted by an air space, said outer wall being at least partially transparent;
- a pump in communication with the cavity, the pump, upon activation, capable of forcing liquid fluid into the cavity and compressing the air space to create currents in any fluid in the cavity;
- a handle affixed to the outer wall;
- and
- means on said handle for activation of the pump.

A cup comprising:
- a base;
- an outer wall mounted to the base, the outer wall including an outlet there through, said outer wall being at least partially transparent;
- a handle affixed to the outer wall;
- an inner wall mounted to the base within the outer wall and spaced apart from the outer wall, the inner wall and the base together forming a recess for holding a beverage, and the inner wall, the outer wall and the base together forming a cavity between the inner wall and the outer wall, the cavity partially filled with liquid fluid surmounted by an air space;
- and a pump located in the handle coupled to the cavity through the outlet, the pump upon activation capable of forcing liquid fluid into the cavity an compressing the air space to generate currents in the fluid in the cavity, and
- means on said handle for activation of the pump.

A cup comprising:
- a main body, the main body including
- a base,
- an inner wall mounted to the base, the inner wall together with the base defining a space having a closed end and opposing open end,
- an outer wall mounted to the base, the outer wall having an outlet, the outer wall being at least partially transparent and the outer wall, together with the inner wall and the base, defining a cavity substantially closed at the base and substantially open at the top opposite the base, the cavity partially filled with liquid fluid surmounted by an air space, a handle affixed to the outer wall;
- an insert adapted to hold a beverage, place substantially in the space within the inner wall, the insert including
- a bottom,
- a continuous sidewall extending up from the bottom, the sidewall, together with the bottom, defining a recess having an open end for holding a beverage,
- a rim connected to the top of the sidewall, the rim extending over the top of the cavity and substantially sealing the cavity,
- a liner located between the side wall of the insert and inner wall of the main body;
- a pump located in the handle and coupled to the cavity through the outlet, the pump upon activation forcing fluid into the cavity and compressing the air space to create currents in the fluid, and
- means on said handle for activation of the pump.
