  • Patent number: 4358992
    Abstract: A cookpot lid according to the instant invention has a lid body formed with two vertically throughgoing apertures and a reservoir overlying the aperture and rotatable on the lid body about an axis adjacent the aperture. The reservoir is formed with two vertically throughgoing holes alignable vertically with the respective apertures in a predetermined angular position of the reservoir on the lid body. The holes and apertures are spaced the same distance from the axis. A stop is provided so that in one end position of the reservoir, which is formed as a handle, the two holes are aligned with the apertures for maximum flow, and in the opposite end position only one of the apertures is aligned with only one of the holes for less flow. In between these positions no hole is aligned with an aperture so no flow is possible.
