  • Patent number: 12110152
    Abstract: A dual-chamber beverage container for reducing a temperature of a hot beverage to a safe and comfortable drinking temperature. The dual-chamber beverage container includes an insulated bottom chamber for maintaining a temperature of a hot liquid, a cooling chamber for receiving and cooling the hot liquid to a comfortable drinking temperature, and a housing. The housing contains a motorized pump operably connected to a power source also contained within the housing. A transport tube extends from the bottom chamber, through a channel within the housing and terminates within the cooling chamber. A switch is disposed on an exterior side of the beverage container and operably connected to the motorized pump such that activation of the switch causes the motorized pump to pump air into the bottom chamber, displacing the liquid and forcing the liquid from the bottom chamber into the cooling chamber through the transport tube.
