Patent Images
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.

Abstract
A carton having side walls and end walls together with a top wall assembly and a bottom wall assembly. The carton is formed of an upper body portion and a lower body portion with the upper body portion severable and removable from the lower body portion. The severed upper body portion forms a closure cap which is applicable over the lower body portion to reclose the carton. Squeeze lines may also be provided to permit the lower body portion to be squeezed thereby facilitating the reapplication of the closure cap over the lower body portion.
