An improved molded structure is provided in the form of a container closure having a base and lid. A resilient elbow connects an extension arm to the lid. A spring link, which includes a first leg, a second leg, and a resilient second elbow connecting the legs, extends between the closure base and lid. A first film hinge connects the link first leg with the extension arm. A second film hinge connects the link second leg with the lid. A third film hinge connects the lid and base. A special panel can be connected by another hinge to the base or lid which includes a first engaging structure. The panel includes a second engaging structure for effecting a snap-fit engagement with the first engaging structure. The closure can be molded as a unitary structure with the panel in a first position, and subsequently the panel can be pivoted about the hinge to a second position with the first and second engaging structures in snap-fit engagement.
