Claims

[Claims for Utility Model Registration] 1. A container made of thin synthetic resin, with a container body and a lid connected together at a hinge on one side, so that the lid can be folded back and the inner periphery of the container can be folded back to form the main body. In a packaging container whose lid is closed by fitting into a convex edge formed on an opening edge of the main body, at least an outer surface of the convex edge of the main body on the side of the hinge portion is inclined inward as it goes downward. The lid is formed into an overhanging inclined surface, and when the lid is closed, the inner circumferential edge of the lid on the hinge side is guided by the slope, and the opening edge of the lid is engaged with the convex edge of the main body. packaging containers. 2 The convex edge of the main body located on the opposite side from the hinge portion is curved so that the central portion bulges outward when viewed from a plane, and the bulge of the convex edge is pressed inward when the body is closed. 2. The packaging container according to claim 1, wherein the lid is locked by an elastic force applied thereto. 3 The convex edge of the main body located on the opposite side of the hinge part and the convex edges located on the left and right sides are curved so that the central part bulges outward when viewed from a plane, so that the convex edges on the hinge part side are curved when the body is closed. 3. The packaging container according to claim 2, wherein the lid is locked by the elastic force of inwardly pressing the bulges of the convex edges on the other three sides. 4 A convex strip that protrudes outward from the upper part of the entire or part of the outer surface of the other three sides of the convex edge excluding the hinge side, and a concave strip that is concave inward on the inner surface of the inner peripheral edge of the lid body. The packaging container according to claim 1, further comprising a locking mechanism.
