Abstract
A carton (11) with parallel flat front and rear surfaces joined by curved sides and a flip-top lid (10) hinged to the carton. The carton is composed of two superimposed layers adhesively secured at a joint line at lapped edges. The outer layer is slit along its front surface parallel to the carton ends and along upwardly extending curves around the sides to a fold line parallel to and raised above the front slit and the inner layer (12) has a cutout in its front surface above the front slit of the outer layer. The cutout curves upwardly short of the sides where tags (13) are cut out of the sides of the inner layer and the outer layer overlaps the inner layer at the carton ends. Top and bottom closures are adhesively secured to the outer layer at the ends of the carton.
