Abstract
A device for opening and closing container lids is configured for controlling the movement of a lid during the opening and closing of the lid. The device includes a fixed plate, which is connected to the container, a spring, which generates a force on the lid, the magnitude of which varies according to the relative position of the lid, and a common rotary shaft that hinges the lid to the fixed plate. The lid receives force of the spring at a point that is remote from the common rotary shaft such that the force exerted by the spring compensates for the weight of the lid.
