A compact cosmetic container comprising: an outer container; an outer cover coupled to the outer container by means of a hinge to be opened and closed; an inner container coupled within the outer container, with a cosmetic being accommodated therein; a sifter coupled to an upper portion of the inner container, the sifter having a discharge-hole through which the cosmetic is discharged, the discharge-hole being covered with a mesh; and a lid coupled to the inner container by means of a hinge to be opened and closed in order to hermetically close the discharge-hole of the sifter, the lid comprising a soft hermetic packing on a lower surface of a bottom thereof and a tool receptacle formed integrally therewith, wherein a cosmetic-applying tool is accommodated in the tool receptacle, wherein the sifter coupled within the inner container comprises a frame, an outer wall surface of which is inclined downward, such that the sifter is reliably coupled to the inner container, and characterized in that a hermetic ring is disposed on and protrudes from the outer wall surface, an engagement recess is formed in the frame, a hermetic locking protrusion is formed on a support wall of the inner container to correspond to the engagement recess, such that the engagement recess is elastically engaged with the hermetic locking protrusion, whereby the sifter is hermetically coupled to the support wall of the inner container, and wherein an anti-push protrusion is formed on the outer wall surface of the frame of the sifter and under the hermetic ring to prevent the outer wall surface from being pushed outwards by compressive close-contact force of the lid closing the discharge-hole of the sifter, whereby hermetic force of the hermetic packing of the lid with respect to the discharge-hole is not lost. an outer container; an outer cover coupled to the outer container by means of a hinge to be opened and closed; an inner container coupled within the outer container, with a cosmetic being accommodated therein; a sifter coupled to an upper portion of the inner container, the sifter having a discharge-hole through which the cosmetic is discharged, the discharge-hole being covered with a mesh; and a lid coupled to the inner container by means of a hinge to be opened and closed in order to hermetically close the discharge-hole of the sifter, the lid comprising a soft hermetic packing on a lower surface of a bottom thereof and a tool receptacle formed integrally therewith, wherein a cosmetic-applying tool is accommodated in the tool receptacle, wherein the sifter coupled within the inner container comprises a frame, an outer wall surface of which is inclined downward, such that the sifter is reliably coupled to the inner container, and characterized in that a hermetic ring is disposed on and protrudes from the outer wall surface, an engagement recess is formed in the frame, a hermetic locking protrusion is formed on a support wall of the inner container to correspond to the engagement recess, such that the engagement recess is elastically engaged with the hermetic locking protrusion, whereby the sifter is hermetically coupled to the support wall of the inner container, and wherein an anti-push protrusion is formed on the outer wall surface of the frame of the sifter and under the hermetic ring to prevent the outer wall surface from being pushed outwards by compressive close-contact force of the lid closing the discharge-hole of the sifter, whereby hermetic force of the hermetic packing of the lid with respect to the discharge-hole is not lost.
