1. A bottle, comprising:
- a bottle body having a mouth with an external thread formed around an outer circumferential surface of the mouth;
an additive storage container having an end plate being in surface contact with an open end of the mouth, a main cap extending downward in an axial direction from an outer circumferential edge of the end plate and having an internal thread combined to the mouth through a screw-type engagement, an inner cap extending in an axial direction from an inner circumferential edge of the end plate and being movably inserted into the mouth, with a discharge port and a hook protrusion provided on an end of the inner cap;
an opening unit comprising a finish plate provided on an upper part of the inner cap, an upper cap extending in an axial direction from an outer circumferential edge of the finishing plate provided on an upper part and having an internal thread combined to the outer circumferential surface of the main cap, and a slider extending in an axial direction from the end plate and movably inserted into the additive storage container in an axial direction, and sealed by a plug at an end thereof;
wherein the plug has a seal protrusion that is combined to a seal groove formed on a lower end of the slider so that the plug is coupled to the slider to be separated from the slider; and
wherein the plug is integrally formed on a lower end of the slider, with a thin tear-off line formed between the plug and the slider.

Abstract
The present invention relates to a bottle, which contains two kinds of materials separately in two spaces in a bottle body and communicates the separated spaces with each other as necessary so that the two materials can be mixed together. This bottle has a bottle body having a mouth; an additive storage container including an insertion part inserted into the mouth, an exposed part exposed outside the mouth; an additive storage container including an insertion part inserted into the mouth, an exposed part exposed outside the mouth and an additive storage space defined therein; an opening unit tightened to the mouth; and separation means for separating the additive storage container from the bottle body.

7. A bottle, comprising:
-
a bottle body having a mouth with an external thread formed around an outer circumferential surface of the mouth; an additive storage container having an end plate being in surface contact with an open end of the mouth, a main cap extending in an axial direction from an outer circumferential edge of the end plate and having an internal thread engaging with the external thread of the mouth through a screw-type engagement, an inner cap extending in an axial direction from an inner circumferential edge of the end plate and movably inserted into the mouth, with a plurality of discharge ports formed around a lower end of the inner cap, and an extension part extending upward from the inner circumferential edge of the end plate so that the extension part is opposite the inner cap, with an external thread formed around an outer circumferential surface of the extension part; a plug mounted to a lower end of the inner cap, thereby sealing an axial opening of the inner cap; an opening unit comprising a finish plate placed on an upper end of the extension part, an upper cap extending in an axial direction from an outer circumferential edge of the finishing plate provided on an upper part and engaging with the external thread of the extension part, and a slider extending in an axial direction from an inner surface of the end plate and movably inserted into the inner cap, so that an end of the slider is sealed by the plug; and wherein the plug is provided at a lower end thereof with a stop ring that engages with a stop protrusion provided around a lower end of an inner surface of the inner cap so that axial movement of the plug relative to the slider is restricted. - View Dependent Claims (8, 9, 10, 11, 12)
