Abstract: A container with a butterfly lid closure has a base portion and two overlapping hinged lid portions for providing a secure vented closure. The container has a base with a top peripheral edge at an open top end. Two hinged butterfly lid portions are secured to the upper peripheral edge at sides of the base. The lid portions are secured to the base in a closed position by locking recesses on the lid portions that engage locking formations on the upper peripheral edge. A groove on one lid portion engages a groove on another lid portion to form a seal where the lid portions overlap. Venting channels formed on the locking formations allow air to pass in and out of the container, but prevent liquids from entering the container. Arched ridges on the container's sidewalls increase the container's rigidity and resistance to top loading.
