Claim:
A beverage container for use with an automobile beverage container holder, the container comprising: (a) an outer shell having a generally curved cylindrical shape, the outer shell having a closed outer-shell end forming a bottom of the container, an opposing open outer-shell end and an outer sidewall extending therebetween, the open outer-shell end having a larger diameter than the closed outer-shell end, the outer sidewall comprising an upper sidewall and a contiguous lower sidewall, the lower sidewall being continuously and inwardly tapered to terminate at the bottom of the container, the lower sidewall being sized and configured to fit securably in the automobile beverage container holder, the outer sidewall having a substantially sharp decrease in diameter as traversed from the upper sidewall to the lower sidewall so as to form a neck proximate a junction of the upper and lower sidewalls, the neck being sized and configured to obstruct the upper sidewall from being inserted into the automobile beverage container holder; (b) an inner shell having an open inner-shell end and an opposing closed inner-shell end defining an inner sidewall therebetween for holding liquid therewith, the inner shell being sized and configured to be received within the outer shell spaced-apart therefrom to form a hollow inter-shell space between the inner and outer sidewalls; (c) a handle connected, at an end thereof, to the container proximate the open outer-shell end, the handle being positioned between the open outer-shell end and the neck so as to allow insertion of the lower sidewall of the outer shell into the automobile beverage container holder; and (d) a stirring mechanism comprising at least one blade paddle disposed within the inner shell proximate the closed inner-shell end, an impeller shaft connected to the blade paddle and configured to rotate about the central axis of the inner shell, a motor for rotating the impeller shaft, a power source to energize the motor, an electric circuit, and a switch electrically connected to the motor and the power source for selectively transmitting power from the power source to the motor, the switch being located on the handle so as to be accessible by a user while the lower sidewall of the outer shell remains inserted in the automobile beverage container holder.
