PROBLEM TO BE SOLVED: To provide a cartridge which allows additives to pass through separately from a container sealed at a neck part (74) with a regular lid, is applied to a container with a neck part open to add the additives to the content in the container, the cartridge being formed by combining a first member (2) in a unique shape that contains the content with a second member (4) in a unique shape having a cutting means (62), while being configured to cut a closing piece (8) of the first member by action of the cutting means to properly displace the closing piece by without requiring excessive force by further improving the cartridge.SOLUTION: A circumferential cut edge (70) is added to each of a cutting piece (66) constituting a cutting means. The circumferential cut edge is extended to one circumferential side from an outside tip and a vicinity thereof of a radial cutting edge. A radial cutting edge (68) is also added, which extends downward and outward in the radial direction from an inside tip (68a) located at the center of a cylindrical body (34) constituting a second member, and further extends to an outside tip (68b) inclined upward and outward in the radial direction. |
