近では熱湯を加圧供給して迅速に飲物を作る試みがなさ
れている。Conventionally, such packages have had the disadvantage that it takes about a minute or more to prepare the drink because the hot water is poured by gravity. In order to improve these shortcomings, attempts have recently been made to rapidly prepare drinks by supplying hot water under pressure.

プ効果が得られない。However, when an extraction liquid such as boiling water is supplied under pressure,
There was a drawback that the upper filter or the lower filter could be damaged. Therefore, if the upper filter or the lower filter is made thicker, a good filter effect cannot be obtained. Furthermore, if a plurality of reinforcing ribs arranged radially around the opening of the container are provided to support the upper filter and the lower filter, the filtration area becomes smaller and a satisfactory drip effect cannot be obtained.

パッケージは任意の取付手段（図示せず）によって抽出
器に着脱自在に取付られる。The package 1 of the present invention has a container 10, as shown in FIGS. 2 to 4. Openings 11.12 are formed in the upper and lower surfaces of the container. A flange-shaped guide surface 13 corresponding to a corresponding mounting surface of the mounting portion 4 of the extractor 2 is formed at the periphery of the opening on the top surface of the container. When the package is mounted on the extractor, this guide surface is fluid-tightly attached to the mounting surface of the extractor via a seal (not shown). still,
The package is removably attached to the extractor by any attachment means (not shown).

着してもよい。The opening at the top of the container is closed by a top filter 14, and the opening at the bottom of the container is closed by a bottom filter 15. These upper and lower filters are attached to the container by any means. More specifically, the periphery of the upper filter 14 is adhered to the opening edge 11a on the upper surface of the container by heat welding, for example, and the periphery of the lower filter 25 is adhered to the opening edge 12a of the lower surface of the container by heat welding in the same manner as described above. Ru. Apart from this, it may also be bonded with an adhesive or the like.

及びポリプロピレンの多数の混合繊維から成っている。What should be noted here is that the upper filter 14 and the lower filter 15 are made of nonwoven fabric. This ensures that the top and bottom filters are sufficiently strong so that they do not tear when the pressurized liquid from the extractor passes through the package. This nonwoven fabric consists of a large number of polyester or polypropylene fibers or a large number of mixed fibers of polyester and polypropylene.

良いコーヒーが約３０秒以内で抽出される。The space inside the container surrounded by the upper filter 14 and the lower filter 15 contains raw material powder 1 for coffee, black tea, green tea, etc.
6 is filled. For example, if this raw material powder is coffee powder, it weighs about 10g. The average particle size of each powder is 1.
00μ to 800μ is preferable. If the powder is regular coffee, it is preferably 600μ to 800μ. In the case of coffee, if the pressure of the pressurized liquid (approximately 50 cc) from the extractor is set to a maximum of 1 kg/cJ, good-tasting coffee with a concentration of about 1% can be extracted within about 30 seconds.

In addition, since the top surface of the package is formed into an inverted cone shape (funnel shape) which is larger than the bottom surface, the extract liquid can enter the cup intensively, and there is almost no splashing of the extract liquid. Furthermore, since there is no reinforcement rib or other material that obstructs the extract, the extract can smoothly enter the cup. The double-sided filter and the bottom filter have a thickness of 30 to 10 g/yy, which is good for extraction, especially 6
A thickness of 0 g/m” was found to be optimal.

又、カップの下方の床面等を汚すことがなくなった。Effects of the Invention According to the present invention, since the upper filter and the lower filter are made of nonwoven fabric as described above, there is a practical advantage that they will not be damaged even when pressurized liquid passes through them. Furthermore, since the non-woven fabric has high strength, the container does not need to be provided with reinforcing ribs as in the past to support the filter, which has the advantage that the container can be easily made and the cost of the package is low. In addition, with the package of the present invention, the extraction liquid always falls in a fixed direction, that is, towards the cup, so there is no splashing of the liquid, and therefore the machine (extraction part) is not dirty, and the floor surface under the cup is cleaned. No more getting dirty.
