PROBLEM TO BE SOLVED: To bring the internal face of a recess and the eternal face of a jig into slidable contact with each other and make corrections to a packaging container so that it is moved to a proper position, even if the packaging container is displaced when the recess is to be pressed by means of the jig so as to deform the lid downward. SOLUTION: A packaging container 11 comprises a container main body 12 formed of polystyrene into a cup shape, and a lid 13 fitted over an opening at the top of the container main body 2 from outside and formed of polypropylene sheet. A push-out hole 15 is drilled in the middle of the bottom wall 14 of the container main body 12, and viscous stuff, such as soft cream, is discharged therefrom. A recess 20 is formed in the middle of the lid 13 and the middle of it is a flat face 21. Also, a projection 22 is formed on the peripheral edge of the recess 20. When the recess 20 is pressed down and deformed, the underside of the polypropylene sheet forming the recess 20 and projection 22 comes into close contact with the internal face of the container main body 12. |
