Abstract
A method of thermoforming a tamper-resistant/tamper-evident container includes forming a cover portion that includes an outwardly extending peripheral flange, forming a base portion including an upper peripheral rim and a skirt depending downwardly therefrom. The upper peripheral rim is configured to communicate with at least a portion of the outwardly extending peripheral flange of the cover portion to hinder access to the container when the container is closed. Forming a hinge joining the cover portion and the base portion such that the vertical height of the hinge correlates with the height of the skirt that depends downwardly from the base portion when the height of the skirt is substantially uniform around the perimeter of the container and forming at least one line of weakness in the hinge, the line of weakness is severed to facilitate removal of the cover portion from the base portion to open the container.
