  • Patent number: 9439495
    Abstract: A compact having a protrusible and retractable puff includes a lower case having a spring seated therein, an upper case having a seating section and a guide section which extend downward through a central portion, a puff assembly fitted into the seating section, the puff assembly having a puff member fixed to a lower portion, a lift fitted into the guide section, and an inner dish positioned on top of the lift. The puff assembly has a switch and a battery. The puff member is coupled to a separate elastic moving body coupled to the puff assembly. A vibrator is accommodated inside the elastic moving body. The puff assembly is coupled to and separated from the upper case, protrudes upward from the upper case under repulsive force of the spring, such that the puff member vibrates when the vibrator is operated by the switch.

  • Patent number: 9345303
    Abstract: A compact having a protrusible and retractable puff includes a lower case having a spring seated therein, an upper case having a seating section and a guide section which extend downward through a central portion, a puff assembly fitted into the seating section and having a puff member fixed to a lower portion, a lift fitted into the guide section, and an inner dish positioned on top of the lift. The lift positioned inside the guide section and pressed downward is subjected to upward repulsive force from the spring positioned under the lift. The puff assembly is coupled to and separated from the upper case. When the puff assembly is separated from the upper case, the lift including the inner dish moves upwards in response to the repulsive force of the spring, causing the puff assembly including the puff member to protrude upwards from the upper case.

  • Patent number: 9144287
    Abstract: Provided is a puff, which enables the user to apply and spread color cosmetics such as a compact or foundation evenly to the skin so as to be have a sensation of close contact, more specifically, a separable variation puff which is configured such that: various puff members are connectable to or separable from a lower side of a coupling main body having a holding part; an elastic moving body into which an oscillator is inserted is connected to and formed at an inner side of the coupling main body; power of the oscillator is controlled by a battery and a switch; and the battery is easily exchangeable through the lower side of the coupling main body. Thus, the puff is advantageous in that the user can effectively transmit vibration of the oscillator to the puff according to a contact degree of the puff to the user's skin.
