ABSTRACT:
A cover effective to be applied to pots, casseroles and similar kitchen containers is described, which is of such size and structural characteristics as to allow use as part of a "pressure pot." The cover comprises an outwardly projecting edge, a cup-like portion which is provided with a rim which extends downwardly to a level lower than said outwardly projecting edge; an essentially annular component, for instance a gasket, located about the rim and capable of contracting or shrinking. The annular component has preferably a segmented perimetral outline, alternately of smaller and larger diameter, the small diameter parts circumscribing, as the component is in the contracted condition, a circle having a diameter lesser than that defined by the projecting edge.
