The invention discloses a rotatably-opened container. The container comprises a container body, and an upper cover which is connected to the neck of a container bottle in a buckled manner, a clamping ring which can stretch out downwards and can be clamped on the inner hole wall of a container bottle opening is arranged in an inner hole of the upper cover, an arch-shaped water outlet nozzle which stretches out upwards is formed in one side of the top face of the upper cover, an arc hole is formed in the position, located on the rear side of the arch-shaped water outlet nozzle, of the top face of the upper cover, an inner hole of the clamping ring is sleeved with a rotary inner cover, a wrench stretching out of the arc hole is arranged on one side of the upper surface of the rotary inner cover, and a water outlet hole is formed in the position, corresponding to the lower portion of the arch-shaped water outlet nozzle, of the upper surface of the rotary inner cover; when the rotary sleeving cover is rotated to enable the water outlet nozzle to coincide with a through hole, liquid in the container flows out through the through hole and the water outlet nozzle, and if the sleeving cover is rotated in the opposite direction, the water outlet nozzle and the through hole are staggered, and liquid in the container cannot flow out; opening and closing of the container are very convenient, and a user only needs to rotate the sleeving cover in the positive direction and the opposite direction.
