A closure for a flowable product is provided. The closure comprises a base (15) and a lid (20). The base comprises a flowable product dispensing passage (30) along the longitudinal length of the base extending from a first end of the base to a second end of the base. The base further comprises a sealing element (40) configured to be coupled within the dispensing passage of the base such that the dispensing passage is sealed and the flowable product cannot pass through the dispensing passage. Additionally, the base comprises a pressing element (50) configured to be pressed and displaced between a first operational position and a second operational position such that when the pressing element is at the first operational position the pressing element does not contact with the sealing element (40) and the flowable product cannot pass through the dispensing passage, and when the pressing element is at the second operational position, the pressing element contacts and breaks the sealing element (40) and the flowable product can pass through the dispensing passage.

Provided are a container cap coupled to the mouth of a container in which contents are contained; and a container to which the container cap is coupled. The container cap includes: a main body part coupled to a container inlet of a container and having an opening formed on an upper side thereof; a cover part connected to the main body part by a hinge part and opening and closing an upper opening of the main body part by hinge rotation; a separation part connected to the cover part by a first connection part and connected to the main body part by a second connection part detachably; and a fixing part formed 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 can be separated from the main body part.
