1. A bottle having two separated spaces in a bottle body, comprising:

  • a bottle body having a mouth with an external thread formed around an outer circumferential surface of the mouth;

    an additive storage container inserted into the mouth, and having a cylindrical additive storage part opened at an upper end thereof and provided with a discharge port at a lower end thereof; and

    an opening unit having an end plate being in surface contact with the open upper end of the cylindrical additive storage part, a main cap extending downward in an axial direction from an outer circumferential edge of the end plate and having an internally threaded portion engaging with the external thread of the mouth through a screw engagement, and a slider extending downward in an axial direction from an inner circumferential edge of the end plate and movably inserted into the cylindrical additive storage part, thus selectively opening or closing the discharge port,wherein the open upper end of the cylindrical additive storage part is integrally provided with a flange that has an outside protrusion extending outward in a radial direction from the cylindrical additive storage part, the outer circumferential surface of the cylindrical additive storage part is provided at a predetermined position spaced apart from the flange by a predetermined distance with an external thread that has a same pitch as that of the external thread of the mouth, and the main cap is provided at a predetermined position inside the internally threaded portion with an outside hooking protrusion that engages with the external thread of the cylindrical additive storage part through a screw engagement and is hooked by the outside protrusion, the outside hooking protrusion projecting inward from the main cap in a radial direction, so that when the opening unit is rotated, the outside hooking protrusion is hooked by the outside protrusion, thus removing the cylindrical additive storage part from the mouth, and,a seal piece inserted into the lower surface of the cylindrical additive storage container at a position where the lower surface contacts the end of the slider.
