摘要： PROBLEM TO BE SOLVED: To provide a fitting container wherein a lid can be easily fitted at the time of heaping contents in a container body for packaging. SOLUTION: A vertical strip rib 15 is provided on an internal face on a side wall of a container body 10 to prevent contents A from protruding up to a flange 13, so that fitting between a protruding line 14 of the container body 10 and a recessed line 24 of a lid 20 may not be prevented. In addition, by providing a protrusion 25 on an internal face of a side wall 22 of the lid 20, the contents A heaped from the container body 20 is located inward from the protrusion 25, thereby allowing fitting.

摘要： PROBLEM TO BE SOLVED: To improve fitting force of an out-fitting container by making an indination angle of a container body and a skirt of a lid with respect to a vertical line specific and by beveling a corner between a flange of the container body and the skirt. SOLUTION: A taper angle α of skirts 15, 25 is made to be 11 to 18 deg.. This is because the larger an inclination angle α of the skirts 15, 25 which are in pressure contact with each other with respect to a vertical line at the time of fitting, the larger fitting force. However, if the taper angle α is made larger, it is difficult to release a mold at the time of molding, and attachment/removal of a lid 20 cannot be easily done. Therefore, a corner of the mold corresponding to a flange 13 of the mold and the skirt 15 is beveled. Since beveling of the mold appears a bevel 14 on a container body 10 as a product, when the lid 20 is to be fitted to the container body 10, the bevel 14 becomes a guide slope for pressure-fitting the skirt 25 into the skirt 15 of the container body 10, thereby enabling easy and smooth fitting.
