Abstract

A cover (200) and a manufacturing method therefor. The cover (200) comprises a dispensing port (212), a detachable plug (250) that is located at the peripheral edge (230) of the cover (200) and integrally formed with the cover (200), and a recess (222). When a sealing structure is formed between the cover (200) and a cup (100), the dispensing port (212) is used for providing an outlet for contents present in the cup (100). The detachable plug (250) comprises a protrusion (255), and the protrusion (255) is used to form another sealing structure between the protrusion (255) and the dispensing port (212). The recess (222) is configured to be detachably coupled with the protrusion (255) so as to keep the detachable plug (250) in the vicinity of the cover (200) when the detachable plug (250) is not in use.
