1. A plastic tamper-resistant/tamper-evident container comprising:

  • a cover portion including an outwardly extending peripheral flange;

    a base portion including an upper peripheral rim and a skirt depending downwardly therefrom, the upper peripheral rim extending substantially about the perimeter of the container and configured to substantially surround the outwardly extending peripheral flange of the cover portion to render the outwardly extending peripheral flange of the cover portion relatively inaccessible when the container is closed; and

    a hinge joining the cover portion to the base portion, wherein 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, the hinge including a frangible section, the frangible section comprising at least one line of weakness which, when severed, forms at least one projection extending from at least one of the base portion or cover portion for facilitating removal of the cover portion from the base portion to open the container.
