Abstract
A carton formed from a unitary blank of paperboard, the carton exhibiting particular utility as a wrapper or container for food products, such as sandwiches. A sandwich may be formed on the wrapper before folding and forming the wrapper into a carton. Or the sandwich may be made and then placed on the wrapper blank, with two opposite ends of the blank then pulled upwardly around the sandwich. Each end is coated with a layer of cohesive material on one surface, these two surfaces being adhered together to form an upper rib of two thicknesses of paperboard, the end walls of the container then being easily manually formed. The cohesive material has the property of sticking only to itself and the coated ends are readily separated and readily reclosed. Instead of conventional adhesive materials, the use of cohesive coatings enables the coated blanks of this invention to be stacked without sticking to each other, and enables the user to close the carton for storage and subsequent use if a food product therein is not completely consumed in one sitting.
