The invention belongs to the technical field of closed containers, and particularly relates to an inclined setpoint closing container cover structure. The inclined setpoint closing container cover structure comprises a connecting base, a cover body connecting piece is hinged to the connecting base through a hinge shaft, a cover body connecting piece is connected with a cover body, a limiting structure for limiting the movement scope of the cover body connecting piece is arranged on the connecting base, and an included angle between the plane where the edge of the cover is located and the container closing plane or the included angle between the container closing plane and a parallel plane ranges from 0 to 3 degrees. According to the inclined setpoint closing container cover structure, cover body inclined setpoint closing is achieved, a cover body is tightly closed, and abrasion to cover body sealing rings and sealing rings at container openings is small.
