The breather pipe comprises a pipe member having a lower part which is vertically mounted on an opening formed at an upper surface of the container and an upper part which is curved downwardly. The pipe member also has an upper throat and regularly circumferentially spaced lower depressions formed at the circumferential surface thereof, and a spherical float positioned in the pipe member between the upper throat and the lower depressions.
