EXAMPLE The main body of the coffee-containing filter pack (1) of FIG. 1 comprises a body (2) and a lid (3) made of a soft and flexible nonwoven fabric, and the body (2) is a circular nonwoven sheet. It is formed into a round plate shape by drawing and has a flange portion at the opening end. As an example, one cup of coffee powder (4) is put in this plate-like body portion (2), and then from the circular nonwoven sheet. The lid part (3) which becomes the above coffee powder (4)
The opening is closed by welding the peripheral portion of the lid (3) to the flange of the body (2) by welding to the opening of the body (2), and the lid (3) of the main body is A flange portion (5) is formed by stacking two sheets on the entire circumference of the shaft.

The filter which can be attached to and detached from the espresso coffee extractor is a filter for one person (d) and a filter for two persons in this example.
It consists of a filter (d ') and each has a round plate shape with many filtration small holes at the bottom. The diameters of the open ends of the round plate shape are the same as each other, but the internal shape is slightly different. Different ,
The total opening area of the filter small holes (e ') of the filter (d') is
Approximately twice as much as the filtration small hole (e) of the filter (d).
It To these filters, the body of the filter pack (1) can be accommodated in the in each filter, also the flange portion (5), when housing the pack body in the filter,
It is extended to受支to be wide riding on the open end of the respective filters.

The operation of the above-mentioned filtration set will be described below together with a use example. First, when extracting espresso coffee, it is as follows. In FIG. 2 (a), a bowl-shaped holder (b) having an openable / closable coffee supply port (c) is removed from the body (a) of the espresso coffee extractor, and the bottom plate is filtered into the holder (b). A filter (d) for one person having small holes (e) ... is set, and a filter pack (1) containing coffee for one person is set in this filter (d).
Is loaded with the flange portion (5) placed on the open end of the filter. Next, as shown in FIG. 2B, the holder (b) is screwed into the extractor body (a) and the filter (d) is attached.
Is pushed up to the hanging pouring nozzle (f) and the opening of the filter (d) is fitted to the lower end of the pouring nozzle (f) to a slight depth, whereby the pouring nozzle (f). The lower end of the filter pack (1) is pushed into the filter (d),
Along with that, the flange portion (5) of the filtration pack (1) is drawn into the small gap between the nozzle (f) and the filter (d) and is attached, and this attachment flange portion (5) becomes packing. The small gap is sealed to prevent the hot water from leaking above the filter (d), and the lid (3) press-fits the filter pack (1) to the lower end nozzle surface of the pouring nozzle (f). Hold in the state of When high-pressure hot water is supplied into the filter (d) from the lower end nozzle surface of the pouring nozzle (f) in this state, the filter (d)
Filtration small hole (e) ... Since the total area is small, a filter (d)
High pressure is applied inside, and high-pressure extraction is performed on the coffee powder (4) of the filtration pack (1), thereby obtaining a whipped strong espresso coffee.

Next, the case of extracting normal coffee is as follows. In FIG. 3, a filter (d ') for two persons is set in a holder (b) removed from the main body (a), and a filter pack (1) containing coffee for one person is loaded in the same as above. . Next, the holder (b) is screwed into the main body (a) to seal a small gap between the pouring nozzle (f) and the filter (d ′) with the flange portion (5) and to filter the same. When the main body of the pack (1) is kept in pressure contact with the nozzle surface of the pouring nozzle (f), and high-pressure hot water is supplied from the lower end of the nozzle (f) in this state, the filtering small holes ( e ') ...
Since the total area is large, even if a high pressure is applied to the filter (d ') momentarily, the pressure immediately becomes a low pressure, whereby the coffee powder (4) of the filter pack (1) is extracted at a low pressure,
Coffee is usually obtained. In the above-mentioned ordinary coffee extraction, the filter pack (1) filters the extract to prevent the coffee from being mixed with powder.
