Interlocking end panel flaps of a carton have locking tabs containing diagonal fold lines allowing the wide toe portion of the tabs to fold back when inserting the tabs in locking apertures which are narrower than the width of the toe portion. Holding tabs connected to the aperture edge adjacent the location of the toe portions of the locking tabs extend completely across the width of the aperture in a straight line to better hold the locking tab in place. |
