Disclosed is a bottle cap 100 that is detachably assembled with an adjacent portion 2 of an opening of a bottle 1, and the bottle with the same. The bottle cap 100 is comprised of a circumferential portion 10 that is shaped to wrap up an outer surface of the adjacent portion 2 of the opening therein; a cap portion 20 that closes an upper side of the circumferential portion 10; a plurality of tamper indication portions 30 respectively extended from a central area of the circumferential portion 10 to a lower end thereof; a bending portion 40 that connects upper ends of the respective tamper indication portions 30 in a line; an opening piece portion 50 comprised of the plurality of tamper indication portions 30 and the bending portion 40; and a recess portion 70 so formed on an inner surface of the circumferential portion 10 as to prevent separation. Accordingly, it is possible to open and close the bottle cap merely with a simple operation with a single hand, to secure the area for the advertisement or the like sufficiently, to reduce the manufacturing costs by reducing the height of the bottle cap, and to increase the productivity by simplifying the manufacturing process.

What is claimed is: 1. A bottle cap that is detachably assembled with an adjacent portion of an opening of a bottle, the bottle cap comprising: a circumferential portion that is shaped to wrap up an outer surface of the adjacent portion of the opening therein; a cap portion that closes an upper side of the circumferential portion; a plurality of tamper indication portions respectively extended from a central area of the circumferential portion to a lower end thereof, which is cut off as the bottle cap is opened; a bending portion that connects upper ends of the respective tamper indication portions in a line; an opening piece portion comprised of the plurality of tamper indication portions and the bending portion; a recess portion so formed on an inner surface of the circumferential portion on a position over the bending portion as to prevent separation; an opening knob protruding outward of an outer surface of the opening piece portion, the opening knob being configured to be capable of being moved upward by a thumb of user's one hand while the user's one hand is grasping the bottle; and a supporting protrusion that is so formed above the opening piece portion on the outer surface of the circumferential portion as to be contacted with the opening knob of the opening piece portion while the opening piece portion is moved upward by a cutting of the tamper indication portion, wherein, as the user moves the opening knob upward by the thumb of the user's one hand grasping the bottle, the tamper indication portion is cut off and then the opening knob is contacted with the supporting protrusion, whereby the use can open the bottle cap with a single hand. 2. The bottle cap according to claim 1, wherein two tamper indication portions spaced from each other are formed. 3. The bottle cap according to claim 2, wherein said two tamper indication portions are so formed that a distance between lower portions thereof are greater than the distance between upper portions thereof. 4. The bottle cap according to claim 1, further comprising a friction generating means provided on an outer surface of the opening knob. 5. The bottle cap according to claim 4, wherein the friction generating means is a knurling. 6. The bottle cap according to claim 5, wherein the knurling is a wrinkled portion formed horizontally. 7. The bottle cap according to claim 1, wherein the circumferential portion is so formed that a thickness of the upper portion thereof is greater than the thickness of the lower portion thereof 8. The bottle cap according to claim 1, further comprising a closing knob protruding upward at a central area from the upper side of the cap portion. 9. The bottle cap according to claim 8, further comprising a recess portion formed on an inner side of the closing knob, the recess portion for increasing elastic force. 10. The bottle cap according to claim 1, the recess portion for preventing separation is formed to a ring shape along the inner surface of the circumferential portion. 11. The bottle cap according to claim 10, wherein a plurality of said recess portions are formed on upper and lower areas of the inner surface of the circumferential portion. 12. The bottle cap according to claim 1, further comprising a cut-away portion formed on a side opposite to the opening piece portion on the circumferential portion, the cut-away portion being formed by cutting away a lower end area of the circumferential portion at a certain size. 13. The bottle cap according to claim 1, wherein a plurality of opening piece portions is formed respectively on positions different from each other on the circumferential portion. 14. A bottle cap that is detachably assembled with an adjacent portion of an opening of a bottle, the bottle cap comprising: a circumferential portion that is shaped to wrap up an outer surface of the adjacent portion of the opening therein, the circumferential portion being formed to have a cross section of trapezoidal shape so that a lower portion of the inner surface thereof is wider than an upper portion thereof, and being formed by an elastic material so that an area of an opening at a lower end thereof can be changed; a cap portion having a closing knob protruding upward at a central area of an upper side thereof, the cap portion for closing an upper side of the circumferential portion; two tamper indication portions respectively having tamper indication recesses formed by partially cutting away the circumferential portion, and connection bridges that connect the tamper indication recesses so as to be cut off as the bottle cap is opened, the tamper indication portions respectively extended from a central area of the circumferential portion to a lower end thereof and being so formed that a distance between lower portions thereof are greater than the distance between upper portions thereof; a bending portion that connects upper ends of the respective tamper indication portions in a line; an opening piece portion comprised of said two tamper indication portions and the bending portion, the opening piece portion having an opening knob protruding outward of an outer surface thereof, the opening piece portion being configured to be capable of being moved upward by a thumb of user's one hand while the user's one hand is grasping the bottle; a supporting protrusion that is formed above the opening piece portion on the outer surface of the circumferential portion so as to be contacted with the opening knob of the opening piece portion while the opening piece portion is moved upward by a cutting of the connection bridges; a knurling portion formed on an outer surface of the opening knob and the supporting protrusion; a recess portion formed to a ring shape along an inner surface of the circumferential portion on a position over the bending portion, the recess portion for preventing separation; a closing knob protruding upward at a central area from the upper side of the cap portion; and another recess portion formed on an inner side of the closing knob, the recess portion for increasing an elastic force, wherein, as the user moves the opening knob upward by the thumb of the user's one hand grasping the bottle, the tamper indication portion is cut off and then the opening knob is contacted with the supporting protrusion, whereby the user can open the bottle cap with a single hand. 15. A bottle on which the bottle cap according to claim 1 is detachably assembled with an adjacent portion of an opening thereof, wherein the adjacent portion of the opening has a cross section of trapezoidal shape so that a lower end of an outer surface thereof is wider than an upper end thereof, and a protrusion for prevent separation that is inserted to a recess for preventing separation formed on an inner surface of the circumferential portion of the bottle cap is formed on an outer surface of the adjacent portion of the opening.
