The present invention relates to a structure of a cap for a vessel combined with a vessel (1) to open and close the vessel. More particularly, the structure of a cap for a vessel comprises: a cylindrical inner cap (200) combined with the upper end of the vessel (1) to be able to be opened and closed; a cylindrical outer cap (300) inserted into the outer diameter of the inner cap (200) to be combined with the inner cap (200); an accessory (100) inserted into the outer cap (300) and the inner cap (200); (additionally) one or more fixing grooves (210) formed by being cut downward in constant width and depth from the upper end of the inner cap (200) and having a fixing guiding surface (212) formed to gradually expand in the shape of a curve or a oblique line from the outer diameter surface of a cut surface at one side toward the inner diameter surface; a cylindrical operation part (400) inserted into the inner diameter of the inner cap (200) to slide in contact with the inner diameter of the inner cap (200); a driving part (500) formed by being partially cut out vertically downward from the upper end of the operation part (400) and having a bent groove (524) in the shape of a groove formed at either or both of the inner and outer diameter surfaces; a pivoting member for making the driving part (500) reciprocatingly pivot around the bent groove (524) toward the center of the inner diameter of the operation part (400) and the outside of the outer diameter; and an attaching and detaching member for locking or unlocking the accessory (100). Therefore, the present invention provides a structure of a cap for a vessel that opens or closes a vessel by combining and fixing an accessory attached to a cap or separating the accessory from the cap as the cap combined with the vessel is not separated. |
