1. A cosmetic container comprising:
an outer container having a tube-shaped outer container body portion and a concave outer container rotatable cap rotatably coupled to a lower end of the outer container body portion;
a concave inner container holder having a tube-shaped holder side portion and a holder bottom portion extending from a lower end of the holder side portion, the inner container holder being installed in the outer container to be able to move upwards/downwards when the outer container rotatable cap is rotated;
an inner container having a tube-shaped inner container body portion and a concave inner container end cap coupled to a lower end of the inner container body portion, the inner container end cap being disposed in the inner container holder, and the inner container being coupled to the inner container holder to be able to move upwards/downwards together with the inner container holder;
a cylinder having a tube-shaped cylinder side portion and a cylinder bottom portion extending from a lower end of the cylinder side portion and having an inlet hole formed therein, the cylinder being installed in the inner container body portion;
a button having a button discharge channel portion, the button being installed above the cylinder to be able to descend toward the cylinder; and
a pumping portion configured to operate such that, when the button descends toward the cylinder, a cosmetic product stored in the cylinder is discharged outwards through the button discharge channel portion and, when the button ascends to an original position, the cosmetic product stored in the inner container is introduced into the cylinder through the inlet hole,
wherein the outer container rotatable cap has a tube-shaped rotatable cap side portion, a rotatable cap bottom portion extending from a lower end of the rotatable cap side portion and having a pressurization plate provided at a center thereof, and a pressurization column protruding from the upper surface of the pressurization plate, and the outer container rotatable cap is coupled to the outer container body portion through the rotatable cap side portion;
the holder bottom portion has a column insertion hole formed therein;
the holder side portion has holder engaging protrusions formed on an inner surface thereof so as to face each other, left deformation assistance long holes are formed in straight shapes in left areas of the holder engaging protrusions, respectively, so as to extend from the lower end of the holder side portion to positions higher than the holder engaging protrusions, and right deformation assistance long holes are formed in straight shapes in right areas of the holder engaging protrusions in parallel to the left deformation assistance long holes, respectively, so as to extend from the lower end of the holder side portion to positions higher than the holder engaging protrusions;
the inner container holder is installed such that an end of the pressurization column is inserted into the column insertion hole;
the inner container end cap has a tube-shaped end cap side portion, an end cap bottom portion extending from a lower end of the end cap side portion, and an end cap engaging ledge protruding from an outer surface of the end cap side portion, and the inner container end cap is coupled to a lower end of the inner container body portion such that the end cap engaging ledge protrudes outwards past an outer surface of the inner container body portion; and
the inner container is coupled to the inner container holder such that the upper surface of the end cap engaging ledge contacts the bottom surface of the holder engaging protrusions, and when the pressurization plate is bent upwards such that the pressurization column pressurizes the end cap bottom portion, the end cap engaging ledge moves upwards past the holder engaging protrusions, thereby separating the inner container from the inner container holder.
