  • Patent number: 11553776
    Abstract: A compact container having a contamination-preventing cooling plate, includes: a discharge mechanism, inside the compact container, for discharging cosmetics; a discharge plate having a discharge hole and a coupling groove formed in the center thereof; and the cooling plate, which is coupled to the upper part of the discharge plate, has an outlet formed in the center thereof, and is made from a metal material. A contamination guard plate is coupled to the coupling groove of the discharge plate so as to block most of the outlet of the cooling plate while leaving only a discharge gap. The contamination guard plate blocks the outlet of the cooling plate, excluding the discharge gap, so as to prevent bacteria or contaminants from entering the outlet from the puff, and the cooling plate, which is made from the metal material, lowers the temperature of the discharged cosmetics.
