2. Description of the Related Art Conventionally, as a method for easily extracting tea, green tea, coffee, etc., a sheet-shaped filter material such as paper, woven fabric, non-woven fabric, etc. is made into a small bag, and the bag to be extracted with tea, green tea, coffee, etc. The tea bag method of filling and extracting is generally well known. Usually, the tea bag system can be easily extracted by putting a small bag filled with the above-mentioned substance to be extracted in an existing container and pouring hot water, but it has the following problems. That is, since the extractables such as black tea, green tea and coffee are packed inside the filter pouch, there is no room in the volume inside the filter, and the extractables swell, expand and expand even when the extract is poured. Such phenomena are restricted. Therefore, the substance to be extracted inside the pouch hardly moves, and it is difficult to perform effective extraction in a short time. Further, if the extraction time is lengthened, bitterness and astringency are likely to occur and the flavor is impaired.

According to such integral molding, the flange portion 1 has the least expansion of the fiber structure of the non-woven fabric, so that the fiber density and the basis weight are the highest, and then the flange lower part 2 and the extraction part 3 are expanded in sequence. is increased, the fibrous tissue of the extraction unit 3 fiber density and basis weight of the lowest, are formed into coarse. Therefore, by providing the flange portion 1 and the flange lower portion 2 having a high fiber density and a high basis weight on the upper portion of the extraction portion 3, the molded filter container 10 can retain rigidity and shape retention. Further, by providing a small-diameter flange lower part having, for example, one step or two or more steps in the inner lower part of the flange part 1, even if the existing container has a small diameter, it is firmly attached to the caliber part of the existing container via the flange lower part 2. Since it can be mounted and stabilized, the filter 10 will not fall into the existing container. In addition, the diameter of the flange portion 1 is usually made large so as to fit different existing containers.

According to the method and the method of use , a synthetic fiber non-woven fabric having a constant breaking elongation is integrally molded into a molded filter container having a flange portion, a lower flange portion and an extraction portion, and the extraction portion has a fiber structure of the flange portion and the lower flange portion. to wrought to be more coarse, excellent rigidity and shape retention of the molded filter container to be obtained, the bottom surface of the molding filter container
It can be easily attached to existing containers with different diameters through the flange or the lower part of the flange without contacting the bottom of the existing container, and the molded filter container can be used even if the extraction liquid is poured in that state. It is easy to handle and does not fall into. Further, by appropriately selecting the fiber gap of the extraction part nonwoven fabric, the extraction target is prevented from passing through and is sufficiently contacted with the extraction liquid to quickly swell, extend and expand the extraction target, which is effective in a short time. Extraction can be done. Thus, shaping filter container obtained by the production method of the present invention, tea useful Te and component extraction filter of green tea <br/>.
