Disclosed is a battery-operated utensil for mixing and pouring drinks and the like. It uses a separate motor to drive a shaft carrying mixer blades, and a separate motor to drive a pump. The motors are turned on one at a time, and drive the respective shafts directly, thus eliminating the use of components such as gears, clutches or ratchets. The design allows ingredients to be poured into the mixing vessel through a filling chute, without removing the housing which caps the vessel, as well as for convenient removal of the housing when necessary, as for cleaning. Various other features are provided to make the utensil particularly inexpensive to manufacture and convenient to use.

A two-motor, battery-operated mixer-pourer comprising: an open top vessel having a bottom wall and a sidewall, and an open top, handle-shaped filling chute extending outwardly from the upper part of the sidewall and communicating with the interior of the vessel; a removable housing capping the vessel and the chute and containing a mixer motor and a pump motor, at least one battery, and a manually operable switching arrangement for turning on only a selected one of said motors at a time, a mixer driveshaft directly driven by the mixer motor and extending downwardly therefrom into the vessel to a point near the vessel\s bottom, a bottom mixer blade affixed to the bottom end of the mixer driveshaft to rotate therewith, at least one upper mixer blade affixed to a higher part of the mixer driveshaft to rotate therewith, a spout having a free end extending outwardly of the housing, a pump conduit extending downwardly from the housing and having a top end in fluid flow communication with the spout and a bottom end near the vessel\s bottom, a pump secured at the bottom end of the pump conduit for pumping liquid from the vessel up through the conduit and out through the spout, a pump driveshaft directly driven by the pump motor and extending downwardly therefrom to the pump to drive it when the pump motor is on, and a brace secured to and extending from the pump conduit to the mixer driveshaft and having an opening in which the mixer driveshaft is journaled for rotation; wherein said switching arrangement has a neutral position in which both motors are off, a mixing position in which only the mixer motor is on to rotate the driveshaft and thereby the mixer blades, and a pumping position in which only the pump motor is on to rotate the pump driveshaft and drive the pump to move liquid from the bottom part of the vessel up through the conduit and out through the spout; and wherein said housing is manually rotatable relative to the vessel to uncover the filling chute and allow mixing ingredients to be introduced into the vessel without removing the entire housing and wherein, in the alternative, said housing can be completely removed from the vessel by lifting it therefrom, as for cleaning; whereby mixing ingredients can be introduced into the vessel through the filling chute, when the housing is on the vessel but rotated relative thereto to uncover the chute, or ingredients can be introduced into the vessel with the housing completely removed therefrom, and whereby when the housing caps the vessel and preferably, but not necessarily, covers the chute inlet, the switching arrangement can be manually operated to turn on only the mixer motor to mix the ingredients and, after sufficient mixing, can be operated to turn on only the pump motor, to pump a desired amount of the vessel\s contents up through the conduit and out through the spout.
