The present invention relates to a structure of a cap coupled to an upper end of a tube container accommodating a liquid or gel content, and to a cap having an anti-oxidation structure comprising: a cap (100) in which an undercut (110) is formed on the inner wall face of the lower end and an outlet (120) for discharging the content upward is formed; an inner cap (200) which is fixed and supported by the undercut (110) of the cap (100) and is inserted and fixed to the cap (100); and a discharge opening and closing member (300) which is provided between the inner cap (200) and the cap (100), is opened by exhaust pressure of the content, and blocks inflow of outside air into a tube container (10) after discharging the content. After using content such as cosmetics accommodated in the container, the outside air is prevented from flowing into the container to prevent an oxidation phenomenon of the content. Accordingly, the content is prevented from deteriorating or discoloring until using the entire amount of content, to improve reliability in use of products. |
