PROBLEM TO BE SOLVED: To provide a carton which can be opened by turning a lid section by which while it gives novelty in comparison with a conventional opening method, it depresses a part of the carton by reviewing the opening structure of the carton fundamentally. SOLUTION: The carton having the lid section provided continuously in a box body via a hinge is the carton which while it provides at least 1 movable face in the extended state in a forward direction of the above box body from the upper portion of the above hinge of the above lid section, it has formed the lever of a substantially see-saw configuration consisting of the above movable face and the above fulcrum by forming a fulcrum abutting against the substantially central portion of the above movable face in the above box body, and it is an one-touch opening carton characterized in that it opens the lid section by making the other end portion of the above movable face raise via the above fulcrum by depressing the one end portion of the above movable face, and by that the above lid section rotates centering on the above hinge by that the upper portion of the hinge of the above lid section is raised by being accompanied with the rise of the other end portion of this movable face.
