Abstract: Cartons for packaging and mailing books and the like include parallel top and bottom walls which are foldably interconnected by a pair of parallel side walls to form a tubular structure and a closure and protecting structure for each end of the tubular structure including end flaps having an inner and outer portion. A pair of hingedly connected tabs formed in the bottom wall of the carton are normally positioned perpendicular to the bottom wall. A notch is formed at one end of each of the end flap outer portions. A closure flap attached to a side wall of the carton is normally coplanar with the end flap outer portions and parallel to the bottom wall. A tear strip formed in the top wall is normally located above the closure flap.

Abstract: Cartons for packaging and mailing books and articles of small thicknesses include parallel top and bottom walls which are foldably interconnected by a pair of parallel side walls to form a tubular structure and a closure and protecting structure for each end of the tubular structure including end flaps having an inner and outer portion. A pair of tabs formed partly in the bottom wall and partly in the inner portion of the end flaps is hingedly connected to the bottom wall of the carton and divided by a score line into an inner portion normally positioned perpendicular to the bottom wall and an outer portion normally positioned parallel to the bottom wall. The width of the tab at the score line is greater than the width of the outer edge of the outer portion of the tab so that the bottom wall end flap maintains the tab inner portion in a perpendicular position against the packaged article.
