A rectangular box carton according to the present invention has generally rectangular front, bottom, back, cover and closure panels. The front, bottom, back, cover and closure panels are consecutively joined at parallel fold lines and the closure panel is overlapped on and connected to said front panel to form a tube of generally rectangular cross section. Left and right endwalls close the ends of the tube. Each endwall has a first endwall flap attached to the bottom panel and covering substantially the entire tube cross section to form the innermost layer of each endwall; a second endwall flap attached to the cover panel and overlying the first endwall flap, said second endwall flap overlapping only an upper portion of the first endwall flap; a third endwall flap attached to the rear panel and overlying a portion of the first and second endwall flaps, the third endwall flap covering only the rear portion of said first and second endwall flaps and having a glue shield extension thereon that covers an additional portion of the second endwall flap; a fourth endwall flap attached to the front panel and overlapping a portion of the first and second endwall flaps and the glue shield extension of the third endwall flap, the fourth endwall flap having a connection notch therein near the corner at which the cover and closure panels are joined, said notch exposing the corner of the second endwall flap nearest the closure panel; and a fifth endwall flap attached to the closure panel, said fifth endwall flap overlying at least a portion of that corner of the second endwall flap that is exposed by the connection notch.
