## Abstract

A self righting floating insulating beverage container consists of a double walled beverage container which is adequately buoyant and balanced to remain upright in a body of water. The adequate buoyancy and balanced is achieved by the buoyant forces available from an annular cavity created by the double wall container configuration and the balance by the non-buoyant or ballasted bottom of the container. The double wall annular space and ballasted weight are determined to maintain the drink container upright in a body of water, without sinking when filled with beverage, and not capsizing when empty. The double wall configuration also provides insulation for the beverage due to the void between the inner and outer walls.

## Claims

### Claim 1

A beverage container designed to float upright when placed in water consisting of a double walled drink container with void circumferential annular space of sufficient profile and volume to provide adequate buoyant forces to float upright when in use and ballasted at its bottom to provide adequate balance to maintain the container upright when empty.

### Claim 2 (depends on 1)

The floating beverage container of claim 1 wherein the ballasted container bottom shall consist of sufficient container material to provide adequate balance to maintain the container upright when empty.
