1. A generally rectangular recloseable carton formed from a single blank of paperboard material, said carton comprising:

  • rectangular side walls disposed in spaced parallel relationship;

    a pair of rectangular end walls foldably connected to and extending between the side walls of said carton;

    opposed rectangular top and bottom walls extending between and foldably connected to the respective side and end walls; and

    a tear strip extending continuously around said carton generally parallel to the top and bottom walls thereof, said tear strip comprising a pair of spaced apart parallel partial cut lines extending into the outer surface of said carton a distance equal to between approximately 20 percent and 50 percent of the thickness of the paperboard material from which the carton is formed, said tear strip further comprising a tear string adhered to the inner surface of the carton at a location thereon generally centrally between the partial cut lines, said tear string having a thickness substantially less than the distance between the partial cut lines, whereby a pulling force exerted on said tear strip causes a tapered severance in the paperboard material from which the carton is formed.
