Abstract
A pair of bi-fold lids covers a container having a depth dimension that is less than half the width dimension of the container. Each bi-fold lid has front and rear sections that are hinged together along a hinge axis. The hinge axis is reinforced by adjacent flanges that overlap one another when the lids are in their closed position. When the lids are open, the front and rear sections fold over on one another to reduce the extent to which they hang down adjacent the sidewall of the container. This permits a container of short height or shallow depth to have lids.
