Abstract
Abstract In order to separate fat from the top of soup or broth or perform other similar kitchen chores, upper and lower vessels are provided with a valve control arrangement in the upper vessel to control the leakage of the heavier component out of the bottom of the vessel into the lower vessel. To provide simple control in a sanitary environment that may be readily cleaned the upper vessel has its bottom slightly coned or funnelled toward a center hole and a tapered rod is inserted into the hole to seal it. Thus the rod, which extends out of the upper vessel may be manually manipulated to control the speed and depth of separation, thus controlling turbulence.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
125 words
A cooking vessel for separating two ingredients comprising a dispensing vessel having a tapered bottom leading toward a centrally disposed aperture through which the contents may pass by force of gravity, a removable plug-like element with a tapered end fitting partly into said aperture to seal the vessel bottom against leakage of the contents, the plug-like element having structure so that it may be manually manipulated to release only a distinguishable part of the ingredients of the vessel through said aperture, and means fixedly mounting said dispensing vessel in an uppermost position over a receptacle vessel so that the dispensing vessel is held still and is adapted to discharge its contents into the second vessel when said plug-like element is manipulated with a single hand.
