  However, in the above-described refill container, when the lid member 32 is opened during makeup when it is desired to use only the refill container, instead of storing it in a compact or the like, the lid member 32 is connected to the connecting portion. Since it is only connected to the case 31 via 34, there is a problem that the lid member 32 swings up and down around the connecting portion 34, the opening posture is not stable, and it is difficult to use. Moreover, in the above-mentioned refill container, if the container 31 or the lid 32 is impacted by dropping it on the floor or hitting other objects around it, the impact is applied through the case 31 or the lid 32. There is also a problem that the refill cosmetic 33a in the decorative tray 33 is easily transmitted to the tray 33 and easily damaged, making it difficult to protect the refill cosmetic 33a, which is the original purpose of the refill container.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a cosmetic container that can stably maintain an open state and is excellent in impact resistance.

  In order to achieve the above object, the cosmetic container of the present invention comprises a container main body having a cosmetic dish receiving recess formed on the upper surface thereof, and a rear end portion of the container main body rotatably connected to the rear end portion of the container main body. A lid that covers the upper surface of the container body, the container body and the lid are integrally formed of a flexible synthetic resin material, and a rear edge and a lid on the upper surface of the container body A rear end edge portion of the lower surface of the body is connected to a central fold line portion, and a triangular plate having the one end portion as a vertex protrudes from at least one end portion in the left-right direction of the central fold line portion, and the upper surface of the container body From the side corresponding to the triangular plate of the left and right side edges of the belt, a belt-like lower inclined plate extending downwardly inclined toward the outside is projected, and the left and right side edge portions of the lower surface of the lid body are provided on the triangular plate. From the corresponding side, a strip-shaped upper side that extends upward and outward When the plates are projected and the rear end edges of both inclined plates are connected to the two sides of the triangular plate adjacent to the apex via the side fold line portion, the transition from the closed state to the open state is performed. In addition, the central fold line portion and the both side fold line portions are bent so that, of the two sides of the triangular plate, the triangular plate moves downward about the one side of the lower inclined plate side, and the one side of the upper inclined plate side is turned over. It is configured that the cover is held in this inverted posture.

A triangular plate as a vertex protrudes, and from one of the left and right side edges of the upper surface of the container main body (side corresponding to the triangular plate) via the side folding line portions on two sides adjacent to the vertex of the triangular plate The rear end edge of the projecting lower inclined plate and the rear end edge of the upper inclined plate projecting from one of the left and right side edges (the side corresponding to the triangular plate) of the lower surface of the lid are connected. Yes. Therefore, when the cosmetic container according to the present invention is not used in a compact or the like but is used only by itself, when the lid is rotated in the opening direction during makeup, the center folding line portion And the folding line part on both sides bends, the triangle plate moves down around the one side of the lower inclined plate side of the above two sides of the triangular plate, reverses so that one side of the upper inclined plate side turns over, and the lid opens It becomes a state. In this open state, if a force exceeding a predetermined level is not applied to the lid, the folding line portions are not bent and the lid does not move in the closing direction or vice versa, and the open state is maintained. Is done. In addition, since the rear edge portions of the two inclined plates are connected by a triangular plate having flexibility, in the closed state, the cosmetic container of the present invention is dropped on the floor so that the two inclined plates are placed on the floor surface. Even if the two inclined plates hit the surrounding object, the impact at that time is buffered by the triangular plate.
