PROBLEM TO BE SOLVED: To provide a packaging container comprising an opening piece that has sufficient adhesivity to keep a lid body from being opened during circulation, and prevents occurence of an adhesive residue so as not to be disfigured after opening thereof.SOLUTION: The packaging container 1 comprises a container main body 10, a lid body 20 and an opening piece 40. In the packaging container in which the opening piece is cut out from one end 40a toward the other end 40b to open the lid body are provided a plurality of adhesion portions 50 that adhere the opening piece to a front plate 12 of the main body along a cutting direction X of the opening piece. At least one of the plurality of adhesion portions is an adhesion portion 51 having an adhesive residue reduced in which width in a perpendicular direction Y to the cutting direction X becomes maximum in front of a rearward end 51a in the cutting direction X and width at the rearward end satisfies a condition (1). The condition (1) is that When an adhesion portion having an adhesive residue reduced has a curved part at the rearward end, width at the rearward end is equal to a diameter of circle of curvature at the rearward end. |
