Abstract
A shipping carton or container that can be readily opened and converted into a display tray without having to use a knife or other sharp instrument. The carton is formed from a blank having four sidewalls and hingedly connected top and bottom end panels. The sidewalls have a line of severance running circumferentially around the carton that defines a continuous butt joint separating the carton into a top cover section and a bottom tray section. A wide tape having a narrow tear filament or strip attached to its inner surface is adhesively attached to the sidewalls' outer surface such that it bridges the butt joint and holds the carton's top and bottom sections together, the tear strip being substantially superimposed over the butt joint. Pulling the tear filament neatly splits the wide tape and separates the carton's top and bottom sections.
