The first body portion 110 may have an internal space 10 inside the cylindrical shape. The inner space 10 may be filled with storage items such as coffee beans, but in addition to this, tea materials may be filled, or gunpowder such as ammunition may be filled to serve as a general ring box.

(Example 1-2) In Example 1-1, the first fusion portion 111 formed on the first body portion 110; A second fusion part 121 formed on the second body part 120;

The support 220 is coupled to the lower side of the filter 210, and the liquid phase filtered by the filter 210 may be discharged to the lower portion of the support 220 through the air gap 221. The liquid phase discharged through the air gap 221 may be discharged to the outside through the extraction unit 300 .

The support 220 may apply pressure upward through a reaction against the pressure applied from above. Therefore, if the size of the air gap 221 provided in the support 220 is too large, a sufficient reaction cannot be generated, and if the size is too small, it may be difficult to discharge the liquid phase. Therefore, the size of the air gap 221 can be adjusted as needed.
