A container has a container portion defining a cavity configured to receive a pin, and a pin disposed in the cavity. The pin is movable within the cavity between a first position and a second position. A spring is disposed in the cavity and configured to bias the pin toward the first position. The container includes a cover movable between an open position and a closed position, the cover having a recess configured to receive the pin. The cover further includes an angled surface configured to contact and move the pin toward the second position to compress the spring as the cover is closed. The recess of the cover is configured to align with the cavity of the container portion when the cover is closed such that the spring moves the pin to the first position and the pin is received in the recess to lock the cover in closed.
