<p>A milk receptacle is provided at the top with an air outlet and at the bottom with a milk outlet controlled by a float-actuated valve comprising an annular disc engageable with an eccentrically disposed valve seat. The disc is connected at its center to the float and is tiltable in a vertical plane against the valve seat as the float rises, thus ensuring gradual opening of the valve by a small opening force.</p> |
