Abstract: A container body (20) includes an upper opening portion (21) having a container internal sidewall portion (22) and a container side skirt portion (24). A lid (10) includes a lid internal sidewall portion (12) and a lid side skirt portion (14). Two or more ledge portions (15) protruding inward are formed on the lid side skirt portion (14). The container side skirt portion (24) includes a first guide portion (30) for guiding downward the ledge portions (15) when the lid (10) is attached. When the lid is closed, the lid (10) is drawn into the side of the container body (20). Thus, a seal portion formed between the container internal sidewall portion (22) and the lid internal sidewall portion (12) is press-contacted, in the state of which the seal portion secures high sealability.

Abstract: A packaging container according to the present invention is molded of a thin synthetic resin sheet. The outer peripheral edge of an opening of the packaging container 1, 18 has an outwardly extended flange 11. The outer peripheral edge 11a of the flange 11 is corrugated in the vertical or horizontal direction. By corrugating the outer peripheral edge 11a of the flange 11, the corrugated outer peripheral edge 11a can give a soft touch to user's hand or finger or a wrapping film contacting the same. As a result, user's hand or finger can be prevented from being hurt and the wrapping film can be prevented from being broken.
