PROBLEM TO BE SOLVED: To provide a paper carton which is excellent in appearance and beautifully disengaged by providing an easily disengaging means. SOLUTION: An upper surface side end face panel 18 has a size enough for covering an end face. A push-in area 20 adjacent to a bottom surface side end face panel 16 is formed on a bottom surface panel 12 by a perforation 12a to connect two points separated from each other on a boundary line from the bottom surface side end face panel 16. A breaking area 21 is formed on the bottom surface side end face panel 16 by two perforations 16a extending to edges opposite to each other with the two points being starting points. The upper surface side end face panel 18 is affixed to the bottom surface side end face panel 16 on a part of its breaking area 21. When the push-in area 20 is broken by a finger and pushed to open, the area can be reliably separated along the perforation 16a, and the separated breaking area 21 and the upper surface side end face panel 18 can be integrally expanded.
