  • Apparatus for the addition of a compound or compound mixture to another
    Patent number: 6916114
    Abstract: An apparatus for the addition of a compound or compound mixture to another which includes a primary vessel adapted having at least one receptacle adapted to contain at least one primary substance. At least one secondary vessel is provided. Each secondary vessel is adapted to contain at least one secondary substance. Each secondary vessel is movably mounted within the primary vessel for movement between a stored position and at least one mixing position. In the stored position, a peripheral edge of each secondary vessel is above a level of the at least one primary substance. In each mixing position the peripheral edge of the secondary vessel is moved below the level of the at least one receptacle containing the at least one primary substance, thereby permitting the at least one primary substance to overflow the peripheral edge into the secondary vessel with the at least one secondary substance.
