An erectable container of paperboard or the like has an integral lid and a novel locking mechanism associated with Beers corner structures for retaining the carton in its erected position. Drag tabs pressing against the bottom panel of the box are provided and are trapped between slits cut in the bottom panel. The slits prevent the drag tabs from returning to their collapsed position, but do not permit the drag tabs to protrude outside the container. The container can be easily erected and loaded and is particularly useful for packaging sandwiches and the like.
