ABSTRACT:
A first break line is formed at a front part of a paper box for storing a film cartridge. Second and third lines connected with the first break line are formed on a top part (lid). The second and third break lines incline toward both edges of the top part. Fourth and fifth break lines connected with the second and third break lines are formed along a ridge part toward both corners of the top part. When the paper box is opened, the first break line is broken to lift the top part, the second and third break lines are broken by the lifting action. Then, the fourth and fifth break lines are broken sequentially, so that the paper box is opened. Therefore, the paper box can be opened on the first attempt.
