A hinge lid for a container including a means for attaching the lid to the container. The attaching means has an exterior and an interior, the interior being proximate to the container when the attaching means is in place on the container. The hinged lid further includes a cover connected to the attaching means in a connection area. The cover has an exterior and an interior, the interior being proximate to the container when the cover is closed. A hinge is located in the connection area. The hinge includes a first rib located at the junction of the interior of the cover with the interior of the attaching means. The axis of the first rib is parallel to the axis of the hinge. The hinge also includes a second rib orthogonal to the first rib. A portion of the second rib is located on the exterior of the cover and a portion is located on the exterior of the attaching means. Another hinged lid having a hinge comprising a recess in the attaching means and a foot connected to and actuated by the cover so that it travels in the recess. A bump in the recess interferes with the travel of the foot, and stable positions of the cover are determined by the location of the foot on either side of the bump. The cover of both hinged lids may also be directly attached to the container, in which case a separate attaching means is not required.
