A compact includes a lower portion, an upper portion, a first mirror, a battery, a circuit, and a coil. The upper portion is movably coupled to the lower portion by a hinge such that the upper portion rotates about the hinge to transition from a closed state to an open state. The first mirror is disposed in the lower portion such that the first mirror is visible when the upper portion is in the open state. The battery is disposed within the lower portion. The circuit is electrically coupled to the battery. The coil is disposed within the upper portion and electrically coupled to the circuit such that the coil produces an oscillating magnetic field when electric power is provided to the coil by the battery and through the circuit.

A cosmetic package comprising a roller for discharging a powder product. The cosmetic package comprises an outer cap, an inner cap, an insert, the roller, a container, and a base plug. The container has an open bottom end which is closed by the base plug. The insert is mounted within the container above a cosmetics accommodating space of the container. A bottom surface of the insert includes two support members for rotatably accommodating two axle projections of the roller such that at least a portion of the roller is disposed rotatably within the cosmetics accommodating space of the container and another portion of the roller extending outside the cosmetics accommodating space from an aperture located at a bottom end of the insert. The inner cap forms a tight seal with the insert and the roller to prevent leakage of powder product from the container.

A modular cosmetic product is provided that includes a container defining a cavity, an insert, a bezel, and a cosmetic product pan. The insert is adapted to be disposed within the cavity of the container and is at least partially constructed from a magnetic material. The bezel is also adapted to be at least partially disposed within the cavity of the container, and includes at least one opening. The cosmetic product pan is adapted to retain a cosmetic product and is at least partially disposed within the at least one opening of the bezel. The cosmetic product pan is at least partially constructed from a magnetic material such that it is urged towards the insert.

A device of axis X for packaging a cosmetic product, includes a base defining a storage compartment and a lid mounted movably in rotation on the base between a closed configuration of the device and an open configuration of the device, a receptacle being arranged in the storage compartment and the lateral wall of the receptacle includes an elastically deformable material.

A compact container is the adjustment of a discharge amount of contents is easy. A compact container includes an inner container; an inner lid in which a communication hole is formed; a middle lid in which a discharge hole is formed; a first valve body; and a second valve body. When the inner pressure of the communication space is increased by the operation portion, the first valve body blocks communication between the communication hole and the communication space and the second valve body allows the discharge hole and the communication space to communicate with each other. When the inner pressure of the communication space is reduced by the operation portion, the second valve body blocks communication between the discharge hole and the communication space and the first valve body allows the communication hole and the communication space to communicate with each other.

A cosmetic jar having a replaceable inner cup is provided. Two symmetric tabs are provided at an upper opening of an inner cup, the tabs each are provided with a tab clamping portion, accommodation regions recessed inward in a radial direction and shaped as a notch are symmetrically formed on an external thread of the outer jar, and an outer jar clamping portion is respectively provided at the accommodation regions. When the tabs are bent downward, the tab clamping portion can be clamped in the outer jar clamping portion to connect the inner cup into the outer jar. After materials in the original inner cup is used up, the empty inner cup can be taken out by releasing the connection between the tab clamping portion and the outer jar clamping portion, and a replacement inner cup is placed and fastened in the outer jar.
