To prevent increase of internal pressure and abrupt burst of a drink resulting from it upon opening a container body of a drink container containing the drink with high temperature so as to pour the drink without a trouble.
A nozzle unit 20 is arranged under a bottom plate 10g of a stopper 10, and a plate-shaped fin 20d and a pair of side plates 20e, 20e are provided on the nozzle unit 20 in a projected manner. The fin 20d is arranged laterally to be apart from a pouring outlet 17 of the bottom plate 10g at a prescribed distance under it. The side plates 20e, 20e are arranged vertically to sandwich the pouring outlet 17 and the fin 20d in-between the side plates. When a drink with high temperature is filled into the container body 2 and the internal pressure of the container body increases, the fin 20 and the side plates 20e suppress the flow rare of the internal pressure to prevent a burst of the drink. When the fin 20d is arranged so as to bend in the direction of the pouring outlet in response to the intensity of the internal pressure, it becomes possible to effectively discharge the drink in response to the intensity of the internal pressure.
