    a glue flap connecting said first side and rear walls, and a top closing structure including a. upper end flaps articulated to the upper edges of said front and rear walls;

    b. upper dust flaps articulated to the upper edges of said side walls;

    c. said upper dust flaps having recessed, angular notch-forming, front corner portions;

    d. a cover hinge line spaced below the upper edge of the rear wall and extending across the rear wall;

    e. a locking element in said front wall and articulated along a hinge line in the front wall in the plane of said cover hinge line;

    f. a horizontal tear line in said glue flap in the plane of said cover hinge line;

    h. said tear strip being generally defined by spaced upper and lower tear lines;

    i. the upper one of said tear lines extending from the free edge of said first side wall below the upper edge thereof, obliquely upwardly to the upper front corner of the carton, then straight across the entire upper edge of the front wall and then obliquely downwardly to approximately the center of the second side wall panel;

    j. the lower tear line defining in part said locking element and extending from the edge of the first side wall completely thereacross and partially across the front wall in the horizontal plane of said cover hinge line and then extending generally parallel to the upper tear line and finally terminating in a horizontal portion, colinear with the initial portion, extending approximately halfway across the second side wall;

    k. a vertical tear line connecting said upper and lower tear lines;

    l. whereby the removal of said tear strip exposes said locking element and forms a telescopically reclosable, lockable chesttype cover which is adapted to completely overlap and be securely locked to the upper raw edges of the said and front walls of the carton upon hinging movement of said cover about said cover hinge line and the folding of said locking element.
