Abstract: An easily recyclable cosmetic container includes a cylinder, a lining and a sleeve. The cylinder includes an outward flange and a shoulder. The lining includes two recesses and an annular ridge. The sleeve includes an inward flange, rectilinear ridges and an annular protuberance. The outward flange is inserted in one of the recesses and the shoulder is inserted in the remaining one of the recesses when the cylinder is inserted the lining. When the lining is inserted in the sleeve, an end of the lining is covered by the inward flange, the annular ridge is located against the annular protuberance, and the rectilinear ridges are in contact with the lining to prevent the lining from rotation relative to the sleeve.

Abstract: A container includes a lid, a frame, and a mirror. The lid includes two external ridges and at least one intermediate ridge formed on a face thereof. The intermediate ridge is located between and in parallel to the external ridges. A height of the intermediate ridge is smaller than a height of the external ridges. The frame includes fins extending from a face thereof. The fins are in parallel to one another. During attachment of the frame to the lid, the fins are slidable on the intermediate and external ridges to render movement of the frame on the lid smooth like swinging of a pendulum. The mirror is attached to an opposite face of the frame.

Abstract: A container includes a cover assembly, a base assembly, magnets and a ferromagnetic element. The cover assembly includes an edge extending around an open end.
