The coffee brewing apparatus of FIG. 17 brews one cup of coffee, which solves such a problem. However, since a large amount of coffee powder is stored in the canister 51, the canister 51 is stored. There is a problem that the coffee grounds touch the air inside and lose the flavor. In addition, the coffee grounds after extraction adheres to the extractor 52 and the discharging mechanism without being completely removed, and the coffee grounds are bitter due to the influence of the coffee grounds, resulting in loss of flavor and hygiene. There is a problem that it is not preferable.

[0008] Such a problem can be said when the substance to be extracted is not only coffee powder but also tea or the like.

In the coffee extracting device of FIG. 18, since the coffee powder 63 is put into the capsule 61 one by one, there is no problem that the flavor of the coffee powder 63 is lost or coffee grounds adhere to the extractor. Although it does not occur, it is troublesome to take out the coffee capsule 61 from the package 62 and load it into the holder.

Further, in the coffee capsule 61 of FIG. 19, since the upper and lower filters 64, 64 are flat, the capsule body 61A having a large inner diameter is required to increase the extraction area.
However, there is a problem that the coffee capsule 61 becomes large.

The present invention has been proposed in order to solve the problems of the prior art as described above, and the flavor of coffee grounds, which is the substance to be extracted, is lost, and coffee grounds are contained in the extractor. It is an object of the present invention to provide an extract-encapsulated capsule in which the problem of sticking does not occur, and the capsule does not have to be taken out of the package and loaded into the extractor, and the capsule can be made smaller.

[0012]

In order to achieve this object, the extract-containing capsule according to the present invention has a cylindrical capsule body capable of maintaining airtightness, in which the extract sandwiched between upper and lower filters is enclosed. Then, the upper opening and the lower opening of the capsule body are sealed with an airtight upper sealing sheet and lower sealing sheet, respectively.

The extract-encapsulated capsule according to the present invention is a capsule body that can maintain airtightness and is sandwiched between an upper filter and a lower filter that bulges downward and widens the extraction area. And the upper opening and the lower opening of the capsule body are sealed with an airtight upper sealing sheet and lower sealing sheet, respectively.

[0014]

According to the above-mentioned structure, the substance to be extracted, for example, coffee powder can be enclosed in an airtight capsule, so that the flavor of the coffee powder can be retained for a long period of time. Also, since the lower filter bulges downward to increase the extraction area,
The extraction speed of coffee powder etc. can be increased. In addition, the capsule containing the substance to be extracted can be directly loaded into the coffee extracting device or the like without taking out from the package.
