Covered dish with vent

An apparatus for cooking, serving and storing food and the like, comprising:

• a dish having a bottom wall and an annular sidewall, said bottom well and sidewall defining a dish interior;
• a cam ledge on said sidewall peripherally about said sidewall;
• a cover having a top wall and an annular sidewall, a lip extending downwardly from said cover sidewall peripherally thereabout;
• said cover being selectively rotatable in opposed directions and vertically movable on said cam ledge between an unvented position wherein said lid engages said cam ledge to block access to the interior of the dish and a vented position wherein said lip partially engages said cam ledge to allow access to the interior of the dish;
• said cam ledge including a first pair of opposed peripherally elongate sections and a second pair of opposed peripherally elongate sections, said first and second sections alternating along said cam ledge with said first sections being vertically displaced downward from said second sections, and two pairs of opposed inclined sections, each inclined section extending between adjacent first and second sections;
• said cover lip including a lower surface contoured to match said cam ledge and similarly include a pair of first sections, a pair of second sections vertically displaced above said first lip first sections, and inclined sections between said lip first and second sections, wherein, in said unvented position, said lip first, second and inclined sections engage with and conform to said first, second and inclined sections of said dish ledge to restrict venting of fluid between said cover and said dish;
• said cover being rotatable beyond said first-mentioned vented position to a second vented position, said cover in said second vented position having said lip first sections received on and supported by said ledge second sections along at least a major portion of the length of these sections to maintain a generally parallel relation between said cover and said dish with a vertical elongate space defined between each lip section and an underlying ledge first section;
• wherein said cover, at said first mentioned vented position being in constant contact solely at opposed pivot points, defining a pivot axis, on one of the pairs of inclined sections of the dish ledge for pivotal movement of said cover relative to said dish about said axis.
