Venting appliance lid

A venting appliance lid, comprising:

• an outer sealing section having a rim and a shoulder defining a central opening and at least one downwardly depending skirt, wherein the rim is defined by an outermost surface of the outer sealing section and wherein the shoulder is provided along an inner circumference of the rim;
• a center cap having a flange and a cup downwardly depending from the flange, wherein in a fully inserted position of the center cap within the central opening the flange rests on the shoulder;
• wherein at least a portion of the downwardly depending skirt is provided with an inner diameter spaced by a gap from an outer diameter of the downwardly depending cup;
• wherein the downwardly depending skirt has at least one expansion notch and the downwardly depending cup has at least one locking tab, wherein the center cap is rotatable relative to the outer sealing section to align the at least one locking tab with the at least one expansion notch and wherein the expansion notch is provided with a height allowing the locking tab to travel a vertical distance equal to the height of the expansion notch;
• wherein exertion of a force on an underside of the center cap while the locking tab is aligned with the expansion notch raises the center cap by the vertical distance and separates the flange from the shoulder whereby the gap forms at least a portion of a vent path between the outer sealing section and the center cap and opening the vent path to atmosphere;
• wherein the downwardly depending skirt further comprises at least one vertical tab track, the at least one vertical tab track having a vertical tab stop at a bottom end of the at least one vertical tab track, the vertical tab track extending below lower rim of the downwardly depending skirt;
• and
• wherein the at least one vertical tab track is provided with a width sufficient to allow the locking tab to travel vertically within the at least one vertical tab track until the locking tab encounters the vertical tab stop.
