Abstract

Abstract A collapsible, carrier carton comprises a split cover, overlay closure with self-erecting handles and a side panel/web flange lock. This web lock permits secure locking of the split cover closure into a flattened and closed configuration and secures the removable upper tray(s) in a locked position. The split cover closure includes opposite side member panels having self-erecting, interlocking male and female handles. One of these side member panels is of a greater than the other to permit a split cover closure overlap which prevents contamination of the container interior when the side panels are closed. The split cover closure also includes outwardly and downwardly folding, notched-out web flaps with alignment holes. Each of these web flaps interlocks in a corresponding contour-crease, inwardly biased, side panel, knife-cut web lock. The carrier carton includes removable upper trays with vent holes. Connected to either end of said trays are end walls and foldably connected, triangularly shaped web flanges alignment holes. These removable tray web flanges align with the corresponding split cover closure web flaps for locking engagement in the carrier carton side panel web locks. The carrier carton frame includes inwardly projecting lower flanges which are glued together to form a partial bottom support upon which a removable bottom tray closure is seated.
