PROBLEM TO BE SOLVED: To stably hold a stored bowl by utilizing a material for forming a bowl storing box. SOLUTION: A cardboard plate (15) is bent to form a rectangular cylindrical box with a bottom segment including a front plate (16), a rear plate (17), right and left side plates (18, 19) and a bottom plate (20). A first separating piece (16a) having its lower end connected to a lower segment of the front plate (16) is arranged at a lateral intermediate segment of the front plate (16). An annular first fitting hole slit line (U1) substantially corresponding to a diameter of a lower segment of a bowl (12a) is formed at an inner circumference segment of the first separating piece (16a). A first folding line (L1 ) extending in a lateral direction is formed at a lower end of the first separating piece (16a); a second folding line (L2 ) extending in a lateral direction is formed at the first separating piece (16a) located at an upper position corresponding to a depth size of the box from the first folding line (L1 ); and a third folding line (L3 ) extending in a lateral direction by a predetermined amount from the second folding line (L2 ) is formed at the first separating piece (16a) located an upper position, respectively. A second separating piece (17a) having one of an upper end and a lower end connected to the rear plate (17) is arranged at an inner circumference of the rear plate (17), and then a second fitting hole slit line (U2) substantially corresponding to a diameter of the upper segment of the bowl (12a) is formed at an inner circumference segment of the second separating piece (17a).
