A lid assembly, adapted to form part of a dispensing container, includes a closed-loop flange, and a lid is joined to and pivots about the flange via a hinge. A spring is joined to the flange at the first and second ends. The flange, the spring, the lid, and an opening button can all be integrally formed together. In a closed position, the lid is stacked above the flange in a height dimension. The spring forms a convex arc whose convexity extends away from the flange in the height dimension when the lid is in the open position. The spring can be curvilinear and have two, three, four, or more points of inflection, such as by being m- or w-shaped. 1. A lid assembly adapted to form part of a dispensing container , the assembly having a longitudinal dimension , a transverse dimension , and a height dimension , the assembly comprising:a flange that forms a closed loop;a lid joined to the flange via a hinge, the lid adapted to pivot about the hinge between a closed position and an open position;a spring in the flange positioned proximate the hinge, the spring having first and second ends, the spring joined to the flange at the first and second ends; andan opening button in the flange positioned longitudinally opposite the spring on the closed loop,wherein the flange, the button, the spring, and the lid are all integrally formed together,wherein the lid in the closed position is stacked above the flange in the height dimension,wherein the spring forms a convex arc flanked by a pair of concave arcs, each of whose concavity extends away from the convex arc in the height dimension, wherein the convexity of the convex arc extends away from the flange in the height dimension when the lid is in the open position,wherein the arc is at least partially deformed toward the flange in the height dimension when the lid is in the closed position, the spring having stored potential energy when the lid is in the closed position, and having no stored potential energy when the lid is in the ...
