A carton, and a method of assembling the same, is disclosed wherein the carton closures or flaps have adhesive applied to or deposited upon particular regions thereof such that the adhesive does not interfere with or foul conveyor or support mechanisms use in connection with the carton assembling or erection equipment carton is erected or assembled in accordance with reverse-fold techniques wherein each end of the carton to be sealed has a first inside major flap folded inwardly, a pair of oppositely disposed minor end flaps are then folded inwardly so as to be disposed atop opposite end portions of the first inside major flap, and a second outside major flap is then folded inwardly so as to be disposed upon the minor end flaps as well as covering that portion of the first inside major flap remaining uncovered by the folded minor end flaps. Longitudinally offset adhesive blocks or patches are provided upon the inside surface of the second outside major flap so as to seal the second outside major flap to the minor end flaps and the inside major flap along the joint or junction lines defined between the pair of minor flaps and the inside major flap. Additional adhesive caulking lines, and embossed or debossed regions, may be provided along the proximal and distal edge portions of the first inside and second outside major flaps so as to complete perimeter seals for the carton ends whereby the carton is rendered sift-proof in connection with powder or granular materials.
