ABSTRACT:
A hinged cover container with integral end cover flaps and handholes is provided with a locking means for securing the end cover flaps and hinged cover to the end walls of the container. When handholes are cut from the end cover flaps of the container, integral locking tongues are produced which are tucked into slits in the end walls of the container to secure the hinged cover to the container and prevent the contents from being spilled when the container is picked up.
