In the above-mentioned nozzle structure, the cooling water supplied from a plurality of water injection ports is caused to collide with the inner wall surface of the nozzle facing the undiluted liquid injection port and to be scattered to the central portion. To mix with the concentrated stock solution. In this case, since the concentrated undiluted solution and the cooling water are mixed in the vicinity of the undiluted solution outlet, there is a problem that the mixed beverage adheres to the undiluted solution outlet and easily becomes dirty. If dirt from the mixture pouring portion such as the undiluted solution pouring port, the water pouring port, and the pouring nozzle is left undisturbed, germs will multiply and become unsanitary. However, in the nozzle structure disclosed in the above-mentioned former publication, the undiluted solution outlet and the dispensing nozzle are tightly fitted to the through-holes and projections formed in the apparatus main body. However, there is a drawback in that it takes a great deal of force to remove or attach the device from the device main body, and this is complicated. Further, with the nozzle structure disclosed in the latter publication, the stock solution outlet cannot be removed from the apparatus body, or the structure inside the apparatus body is complicated, and it is difficult to reliably clean the concentrated stock solution and the coolant outlet. Met.

Further, as described above, in any of the nozzle structures, the cooling water is supplied radially and obliquely from a plurality of water injection ports toward the inner wall surface of the nozzle. The cooling water was spirally rotated, and the residence time of the cooling water inside the nozzle was long. For this reason,
It is pointed out that the time required for one-time dispensing of a mixed beverage of the concentrated undiluted solution and the cooling water becomes longer, and the efficiency of continuous dispensing decreases.
