Decorative cup

Claim 2

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.

Claim 3

The cup of claim 1 wherein the cavity also contains decorative particles that are moved by currents in the fluid.

Claim 4

The cup of claim 1 wherein the cavity is sealed.

Claim 5

The cup of claim 1 wherein the inner wall is at least partially transparent.

Claim 6

The cup of claim 1 wherein the cup is made substantially of plastic.

Claim 7

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.

Claim 8

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.

Claim 9

The cup of claim 6 wherein the pump comprises a bellows and the currents are generated by manually depressing the bellows.

Claim 10

The cup of claim 6 wherein the pump comprises a piston and the currents are generated by manually depressing the piston.

Claim 11

The cup of claim 6 in which the cavity contains decorative particles.

Claim 12

The cup of claim 6 wherein the cavity is at least partially filled with at least two distinct immiscible fluids.

Claim 13

The cup of claim 6 wherein the cavity is sealed.

Claim 14

The cup of claim 6 wherein the inner wall is at least partially transparent.

Claim 15

The cup of claim 6 wherein the outer wall is at least partially transparent and the inner wall is at least partially opaque.

Claim 16

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.

Claim 17

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.

Claim 18

The cup of claim 14 in which the pump comprises a bellows, the currents being generated by manually depressing the bellows.

Claim 19

The cup of claim 14 in which the pump comprises a piston, the currents being generated by manually depressing the piston.

Claim 20

The cup of claim 14 in which the cavity is at least partially filled with at least two immiscible fluids.

Claim 21

The cup of claim 14 in which the inner wall is at least partially transparent.

Claim 22

The cup of claim 14 in which the cavity contains decorative particles.
