Abstract
A plastic container having a container body and a permanently attached container lid is provided. The container lid is attached to the container body by a living hinge such that the entire plastic container is a one-piece construction. The container lid is pre-curved such that in an open state the container lid is curved. However, when the container lid mates with the container body in a closed state, at least a portion of the container lid that was previously curved becomes substantially planar such that portions of the lid remain biased into the container body.
