PROBLEM TO BE SOLVED: To provide a hinge cap which does not block an extraction cylinder and also certainly seals the extraction cylinder even when viscosity of the content is high after the hinge cap is once opened and the content of a container is used.SOLUTION: In a hinge cap which is constituted by openably/closably connecting a cap body 10 with a top cover 20 by a hinge 30, the tip of an inner ring 23 of the top cover 20 is provided with a scrape-off part 25 which is thin and extends outward toward a lower part, tight seal inside a container 2 after breaking of a brittle line 15 is held by the tight seal of the outer surface of the scrape-off part 25 to the inner peripheral surface of an extraction cylinder 13 of the cap body 10, an open scheduled part 16 is cut by a pull ring 18 to be opened, after extracting the content 4 in the container 2 from the extraction cylinder 13, when the top cover 20 is put on the cap body 10, the content 4 of the container 2 adhered to the side of the extraction cylinder 13 to remain is scraped off by the scrape-off part 25 at the tip of the inner ring 23. |
