Abstract

An improved drinking-beaker assembly is provided which serves as both a drinking vessel, especially the drinking of water in the course of a diet, and a device for determining the precise amount of liquid consumed. The assembly preferably includes a beaker, a snap-ring collar, indicia for the number of uses and indicia for the volume level within the beaker. The beaker has a base, a wall and an open top. Portions of the wall define an annular groove having an upper rib, a bight and a lower rib. The collar is snugly fitted within the groove for manual, axial rotation of the collar relative to the beaker. The collar further includes a window which is aligned with the use indicia to sequentially indicate the number of consumptive uses of the assembly. The user may fill the beaker to the level of the volume indicia, consume the liquid from the beaker and then rotate the collar with resepct to the beaker so that the window exclusively displays the number of the indicia means associated with the use so that the total volume of liquid consumed is known.
