Lid assembly for a liquid container

A lid assembly in combination with a single piece container for liquids, the container comprising:

• a container wall defining an opening;
• a pair of downwardly projecting slanted flanges, the downwardly projecting slanted flanges including a first wall extending circumferentially from the container wall in a direction away from the opening defined by the container and a second wall extending from the first wall in the direction away from the opening defined by the container and in a plane generally parallel to the container wall, the second wall defining a slanted edge of the second wall, the slanted edge defining a first distance from the opening of the container wall at a first position and a second distance from the opening of the container wall at a second position, the second distance being greater than the first distance, the second position being spaced from the first position in the plane generally parallel to the container wall, the slanted edge extending continuously between the first and second position;
• and
• a pair of separate holding devices, each holding device extending circumferentially away from the container wall, the lid assembly comprising:
• a lid;
• two fastening clamps attached to the lid for fastening the lid assembly to the container, the two fastening clamps being arranged at lateral sides of the lid;
• and
• a pair of separate hinge arms attached to the lid which extend to a respective holding device arranged on the container;
• wherein
• the lid is pivotably held by the pair of separate holding devices on the container;
• each of the fastening clamps is formed in one piece on the lid;
• each of the fastening clamps extends from the lid in a direction of the container and includes a slanted hook-shaped free end, the slanted hook-shaped free end defining a surface corresponding to the slanted edge of the second wall of a respective slanted flange of the container;
• the slanted hook-shaped free end of each of the fastening clamps extends behind the respective slanted flange on the container;
• each of the slanted flanges is arranged adjacent a respective fastening clamp, and
• the slanted hook-shaped free end of each of the fastening clamps includes a chamfer which extends behind the respective slanted flange of the container.
