Container cap and container having same coupled thereto

A container cap comprising:

• a main body part which is coupled to a container inlet of a container containing contents and has an opening defined in an upper side thereof;
• a cover part which is integrally connected to the main body part by a hinge part to open and close an upper opening of the main body part by hinge rotation;
• a separation part which is integrally connected to the cover part by a first connection part and is integrally detachably connected to the main body part by a second connection part;
• and
• a fixing part disposed on the cover part so that the separation part is fixedly coupled thereto after the second connection part is separated by a user's manipulation so that the cover part is separated from the main body part;
• wherein the separation part is provided with one or more concave parts when viewed at an upper side in a state of being connected to the main body part, and
• the fixing part is provided with a protrusion fitted into a concave part of the separation part by separating and tilting the separation part from the main body part;
• and
• wherein the concave part has a narrow inlet portion based on an insertion direction, and
• the protrusion has a wide width at an end portion thereof to correspond to the inlet portion of the concave part.
