ABSTRACT:
A beverage mixing vessel or drink shaker has internal features effective for breaking up ice as the beverage mixing vessel or drink shaker is shaken. One or more protrusions disposed near the bottom of a container have apexes aligned in the direction of shaking motion. The impact of ice cubes upon the apexes of the protrusions facilitates breaking the ice cubes into smaller pieces, thereby having the effect of cooling a mixed beverage more quickly.
