Abstract
A container comprises a sheet of polymer formed into a base portion. The base portion has cavities for receiving and supporting frangible items. A cover portion has cavities for covering the frangible items. The cover portion has a flat peripheral wall defining concavities. A first hinge rotates the cover portion onto the base portion to hold the items captive. An elongated tab has male connectors oriented with a ramp portion. A female connector projects from the peripheral wall of the cover portion and is in vertical alignment with the male connectors. A second hinge rotates the tab toward the interior of the base portion. Connectors block the cover portion to the base portion when closed together. A grasping wall spans between and projects from the receiving cavities and from the container, defining a grasping surface. A clearance is positioned between the female connector and the base portion when the container is closed.
