Patent attributes
Embodiments of a multi-compartment beverage bottle system and methods of manufacturing the system are disclosed. First and second housing elements are in mutual engagement with one another to at least partially define a fluid vessel with a fluid cavity therein. The fluid cavity includes a first fluid compartment and a second fluid compartment. The first housing element is rotatable between a storage position and a mix position with respect to the second housing element. A shuttle element is disposed within the fluid cavity and axially actuatable along the main axis into and out of a seal position. Rotation of the first housing element toward the storage position actuates the shuttle element toward the seal position. Rotation of the first housing element toward the mix position actuates the shuttle element away from the seal position, thereby placing the first and second fluid compartments into fluid communication with one another for mixing.
