It is installed between (c3) and a portion where the tip of the cover portion 512 forming the inlet hole (i3) is formed. According to this second sealing member 514, when compression is performed, the fluid w leaks between the capsule-type coffee cartridge c3 and the tip portion of the cover part 512 forming the inlet hole i3. Can be effectively prevented.

According to the cartridge portion 510 including the base portion 511, the cover portion 512, the first sealing member 513 and the second sealing member 514 as described above, the capsule type coffee cartridge (c3) You can brew coffee using.

According to the coffee extraction apparatus 500 according to the fifth embodiment of the present invention including the cartridge unit 510, the pressure unit 420 and the accommodation unit 430 as described above, a capsule type coffee cartridge (c3) There is an effect that can be used.

In addition, according to the coffee extraction device 500 according to the fifth embodiment of the present invention, there is an effect that the disassembly and assembly of the device is very easy and maintenance is very simple.

Hereinafter, a modified example of the pressure portion of the coffee extraction apparatus according to the first to fifth embodiments of the present invention will be described with reference to the accompanying drawings.

27 shows a modified example of the pressure portion of the coffee extraction apparatus according to the first to fifth embodiments of the present invention.
