Chimney vent cap

A chimney vent cap for controlling flow of exhaust gases from a cooking device having a base and a lid movable relative to the base with the lid having a chimney through which the exhaust gases exit, the chimney vent cap comprising:

• a base member adapted to receive at least a portion of the chimney of the cooking device within the base member at a first end, the base member being adapted to receive exhaust gases flowing from the chimney in a predominant direction, the base member having an opening at a second end to permit exit of the exhaust gases;
• a control member without holes adapted for selective movement by a user relative to the base member into a plurality of configurations of the control member and the base member to control the flow of exhaust gases from the base member through the opening by occluding the opening using the control member, wherein the control member comprises a stop protruding from the control member into the opening of the base member, and wherein the stop engages an edge of a protruding support portion of an end wall of the base member, the edge of the protruding support portion defining the opening at the second end of the base member;
• wherein the control member and the base member are operable to control the flow of exhaust gases from the chimney without changing the predominant direction of travel of the exhaust gases and without insertion of the user's fingers into the exhaust gases;
• and
• a retaining means adapted to retain the respective configuration of the control member and the base member in response to movement of the lid of the cooking device relative to the base of the cooking device during opening or closing of the lid when the cooking device is in use for cooking, wherein the retaining means is embedded in the base member and a portion of the control member is always over the retaining means.
