Abstract
A container for pneumatically stirring a beverage. Current flow displaced from a flexible member, such as a depressible bulb, is regulated through an outlet optionally containing a one-way valve into an opening in a liquid receptacle. The resultant current flow in the receptacle initiates a stirring motion in the beverage. Air expelled from the depressible bulb may be replenished through an inlet in the bulb.
Claims3
A beverage container comprising:
- a receptacle portion for containing liquid;
- a handle portion comprising a depressible bulb having an outlet at one end coupled to an opening in the receptacle portion, wherein air is forced into the receptacle portion through the opening to stir a liquid contained therein upon pressing the depressible bulb, wherein the depressible bulb has an inlet operable to receive current flow into the depressible bulb, and wherein the inlet further includes a removable cap for permitting access to the depressible bulb to flush the bulb.
A beverage container comprising:
- a receptacle portion for containing liquid having an opening;
- a handle portion comprising an inlet, an outlet and depressible bulb coupled to the inlet and outlet, the outlet coupled to the opening in the receptacle portion, wherein the depressible bulb is operable to receive air from the inlet and expel air out the outlet to force the air through the opening in the receptacle portion to stir liquid contained therein, wherein the inlet further includes a removable cap for permitting access to the depressible bulb to flush the bulb;
- and
