Abstract: A container cover comprises two halves that are integrally-molded. The two halves are connected by a common pivot point or hinge that is disposed to one side of each half which allows the halves to be folded over and onto one another. One half is a solid cover or lid structure (the “lid”) and one half is a ring-like base structure (the “base”), both of which are intended to be disposed atop a container, with the base in direct contact with the container although the lid and base could be modified the include other engaging structure. The lid is configured to fit with and engage the base via the common hinge or pivot point. Opposite the hinge point of each structure is part of a lock structure that provides the tamper-evident functionality when the lid is folded over and attached to the base.
