It concerns a tetrahedral extraction bag with BACKGROUND OF THE INVENTION Brew bags, such as tea bags, have traditionally been formed from water permeable sheet materials such as paper, non-woven fabrics, and woven fabrics. As shown in FIG. 2, such a conventional extraction bag is made by folding one water-friendly sheet in half and binding the joint and bottom of the bag to form two sides, one on the front and one on the back.
．． 1', and after storing the material to be extracted 4, for example, a flaky material such as green tea, black tea, or dried bonito flakes, into the space formed between the front and back surfaces 1 and 1' from the opening at the top of the bag. The opening at the top was closed and glued to form a bonded part 2, to which a hanging string 9 was tied as desired. In such a bag-like body, the space formed between the front and back surfaces for accommodating the material to be extracted is small, and the material to be extracted absorbs water and swells during extraction, increasing its volume by 2 to 5 times. As it increases,
There was a problem that the extraction water did not flow sufficiently between the flakes of the material to be extracted, resulting in insufficient extraction effect.

していてもよい。Also, attach a hanging string to the two-sided bag-shaped extraction bag,
It is also known to allow the extraction bag to swing up and down in hot water, but the direction of this swing is parallel to the front and back sides of the bag, and the material to be extracted inside the bag is It was rather difficult to circulate hot water sufficiently between the flakes to be extracted because they were compressed by the two sides. Utility Model Publication No. 60-27059 discloses a tea bag that can be extracted using a single filter. This tea bag is a triangular pyramid-shaped bowl with no bottom surface, formed by two superimposed water-permeable sheets, and a substance to be extracted is filled between the two sheets and sealed. It is. This bag is shaped like a bowl with its triangular pyramid apex facing downward, and by pouring boiling water from above, the bag can be used like a filter to perform the desired extraction. However, when this is put into hot water as a normal extraction bag, the material to be extracted is contained in the narrow space between the two stacked sheets, so the hot water does not flow between the flakes of the material to be extracted. This was insufficient, and therefore a satisfactory extraction could not be obtained. SUMMARY OF THE INVENTION Therefore, the present invention aims to solve the above-mentioned problems of conventional extraction bags and to provide a new extraction bag that can sufficiently extract substances to be extracted in a relatively large extraction space. [Means and effects for solving the problems] The extraction bag of the present invention is a tetrahedral container formed of a water-permeable sheet, and a tetrahedral container containing a material to be extracted contained in the container. This is a type extraction bang. In the extraction bag of the present invention, the tetrahedral container may have at least one hanging thread extending from its outer peripheral surface.

Shape the binding part D and bind the bottom part to form the binding part E. The bag is filled with a desired amount of material to be extracted (not shown), and then both edges F and G of the opening are opened in the direction of the arrow (i.e. , perpendicular to the binding part E) so that the midpoints H and J of the overlapping edges F and G are at both ends of the overlapping part, as shown in Figure 3D. , this overlapping part is bound to form a bound part K. As a result, a tetrahedral container with four sides formed by a single water-permeable sheet is obtained. The water-permeable sheet used in the present invention may be paper, non-woven fabric, or knitted fabric, but for example, if a monofilament fabric of nylon 6 is used, it has a moderate aperture ratio, good water permeability, and is odorless for extraction. A container is obtained. There are no particular limitations on the dimensions of this tetrahedral container, and they can be set as appropriate depending on the purpose. Further, the tetrahedron may be a regular tetrahedron or a scalene tetrahedron.

分に抽出させることができる。One end of the hanging string 9 is glued to the outer circumferential surface of the container at the bonding point 6. A tag 8 may be glued to the other end of the hanging string 9. Before use, if the tag 8 is removably attached to the outer circumferential surface of the container, the hanging string 9 will be fixed, and the extraction bag will be fixed. During handling, the hanging string 9 may become tangled, causing an inconvenience. This eliminates the possibility of misalignment. One end of the hanging string 9 can be glued to any point on the outer circumferential surface of the container. For example, as shown in Figure 4,
If the lower end of the hanging string 9 is glued to a position close to one vertex of the tetrahedral container, the apex of the container will be directed upward by swinging the brewing bag placed in the teapot up and down with this hanging string. The hot water 10 flows in and out vertically through this triangular bottom surface, allowing the material to be extracted in the container to be easily and sufficiently extracted.

むようになる．For example, as shown in Fig. 5, when the lower end of the hanging string 9 is glued to the center of the ridge on one side of the tetrahedral container and it is hung, one vertex opposite to that side will point downward, and the hot water will not flow. , enters and exits the container through the three sides of the triangle, and when pulled up, water can be drained from the three sides in a short time. [Example] The present invention will be further explained by the following example. <Example> A 110 mesh plain woven fabric woven from 20 denier nylon 6 monofilament was used as a water permeable sheet. This sheet had a high aperture ratio of 65% and had sufficient water permeability for practical use. From this sheet, 3rd A-
By the method shown in Figure D, the length of one edge is 7.
Make a 5CI+ regular tetrahedral container, store 2 to 5g of black tea in it, glue a hanging string with a length of IOCI as shown in Figure 5, and attach a 2cm square to the tip. A tea bag was manufactured by attaching a tag. In this tea bag, the sheet made of nylon 6 monofilament yarn has sufficient resistance and elasticity, and since the threads are arranged in the bias direction on the four sides of the tetrahedral container, the resulting tetrahedral shape is The tea bag was able to maintain its shape and had good resilience against deformation caused by external forces. When this tea bag was used to brew tea in a tea cup, good quality tea was obtained within a short period of time, and when the tea bag was taken out, the water drained well. [Effects of the Invention] The extraction bag of the present invention contains a material to be extracted in a tetrahedral (triangular pyramid) shaped container having a relatively large internal space, and has a large outer peripheral area compared to the volume of this space. Therefore, in the extraction operation, water circulation and stirring of the extracted material are good. Therefore, extraction is carried out efficiently within a short period of time, and in the case of tea bags, for example, tea with excellent aroma and taste can be easily obtained. These extraction bags are individually wrapped and packaged, but if the hanging string tag is removably adhered to the outer circumferential surface of the container, there will be no inconvenience caused by the hanging string getting tangled during packaging, and automatic packaging will be facilitated. Moreover, the consumption of packaging materials will also be reduced.
