[PROBLEMS] To fill heated water into a preparation by pressurization, and particularly when the product is a tea leaf, filling of the heated water has been started in order to appropriately extract the flavor from the tea leaf. In the process, air can be dissipated from the supply device, but when the heating water is completely filled, a supply device that can be prepared such that air flows while pressurizing the supply device or the package is provided. To do. An infusion opening required for supplying an infused drinking liquid, an outflow opening at the upper end, and a discharge opening for discharging the drinking liquid prepared from the preparation chamber mechanism are provided, and Holding mixing chamber mechanism, heater for heating the infused drinking liquid, mechanism for transferring drinking liquid heated from the heater to the infusion opening, and the heated drinking liquid connected to the outflow opening and When the mixing chamber mechanism is initially filled, it opens, and when the heated drinking liquid reaches a predetermined level in the mixing chamber mechanism, it closes during the mixing operation in the mixing chamber mechanism. By this, it is a mixed drink supply apparatus which makes the 1st valve which pressurizes with respect to the said heated drink liquid as a component, Comprising: The drink liquid and preparation by which the said injection pouring opening was inject poured in the preparation chamber mechanism Stirring shape And by having an injection direction can be achieved the above objects blended beverage supply device.
