Abstract

A bottle containing 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 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. The bottle saves resources and prevents deterioration in the properties in the material and additive. A user can mix the material and additive at a precise ratio, thus preventing their chemical and physical properties from deteriorating. The additive storage container can be completely removed from the bottle body.

Claims

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.

2. The bottle according to claim 1, wherein the cylindrical additive storage part has an internal ratchet around a circumference of a root close to the flange, and an end of the outside hooking protrusion is provided with an external ratchet that is allowed to rotate only in one direction relative to the internal ratchet.

3. The bottle according to claim 2, wherein the flange further comprises another flange that has an inside protrusion extending inward in a radial direction, and an inside hooking protrusion to be hooked by the inside protrusion projects outward from the outer circumferential surface of the slider in a radial direction at a position corresponding to the outside hooking protrusion so that, when the opening unit is rotating, the inside hooking protrusion is hooked by the inside protrusion, thus removing the additive storage container from the mouth.

4. The bottle according to claim 3, wherein the outer circumferential edge of the end plate is integrally formed with an upper cap that closes an upper part of the slider.

5. The bottle according to claim 4, wherein the end plate is provided with at least one communication hole that is opened or closed by the flange.

6. The bottle according to claim 1, wherein the outer circumferential surface of the cylindrical additive storage part is provided with a plurality of sealing protrusions that are in contact with an inside surface of the mouth, thus maintaining a sealed state between the additive storage part and the mouth, and a lower surface of the cylindrical additive storage container gradually protrudes upward to form a convex shape.

7. The bottle according to claim 3, wherein an extension part is formed in an axial direction around the outer circumferential edge of the end plate, with an upper cap selectively combined to the extension part.

8. The bottle according to claim 7, wherein a partition wall integrally projects upward from a lower surface of the cylindrical additive storage container and divides the additive storage part into two parts, and the upper cap is provided with an insertion groove into which an upper end of the partition wall is inserted.

9. The bottle according to claim 7, the upper cap is integrally connected to the main cap by a connection rib.

10. The bottle according to claim 7, wherein the extension part is provided with an external thread which has a same pitch as that of the external thread of the mouth, and a top cap having an internal thread is combined to the external thread of the extension part through a screw engagement.
