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. The container incorporates at least one projection that acts as a detent-catch mechanism to secure the lid to the body. The projection reduces the likelihood that the seal formed between the lid and the container when in a closed position will be inadvertently broken.
