[Problems to be solved by the invention]
When the above-mentioned container is accidentally overturned or stored like a tube container, the ball-shaped valve element separates from the lower ridge and moves to an intermediate position between the upper ridge, and at this time, the stored liquid becomes a valve. It may leak from around the body to the spout. In particular, this tendency is remarkable at the beginning of use when the viscosity of the stored liquid is low and the container is full of the liquid. In addition, there is room for the liquid to pass through the periphery of the ball-shaped valve element from the lower ridge to the upper ridge during the liquid pouring, and to reach the spout. There is room to go away.
