    • PROBLEM TO BE SOLVED: To provide a method for obtaining a water permeable sheet with good size stability by reducing the boiling water shrinking ratio of a biodegradable water permeable sheet used for an extracting container for a tea bag or the like. SOLUTION: A fabric is obtained by weaving a flat-woven texture or the like by using Poly-L-lactic acid monofilament for warps and woofs. The fabric is soaked in refined water of 40°C. It is desirable that the refined water is an alkalescent water solution. It is also desirable that the fabric is dried by air after refinement. Then the biodegradable water permeable sheet is obtained by set processing under 120°C atmosphere. It is desirable that the boiling water shrinking ratio of the biodegradable water permeable sheet is 3.50% or less for both the warps and the woofs. The boiling water shrinking ratio is measured by soaking the sheet in boiling water of 100°C for three minutes. The extracted solution of tea bag or the like can be obtained by forming bags using this biodegradable water permeable sheet and containing tea leaves or the like inside the bags.

    • PROBLEM TO BE SOLVED: To provide a bag-like body for a tetrahedron-shaped container, which can be formed consecutively from an elongated water permeable filtering sheet, a manufacturing method for the bag-like body, a tetrahedron-shaped extraction bag using the bag-like body, and a preparation method for the extraction bag. SOLUTION: The bag-like body has front and back faces, which are continuous at their both side ends. Both faces have respective left/right half portions, which are glued together at the center of each face, and the bottoms of both faces are also glued together. On the left half portions of both faces, an inner fold-back part is formed to extend from the top of the left half portions. The right half portions of both faces has an outer fold-back part with the arrangement of a hanging tape or a string to extend from the right half portions. Respective both ends of the inner/outer fold-back parts and the hanging tape or string are glued together at the center gluing area of both faces. The bag-like body having the above structure is useful for preparing the tetrahedron-shaped extraction bag. COPYRIGHT: (C)2005,JPO&NCIPI

    • PROBLEM TO BE SOLVED: To surely and largely open the mouth of a bag attached to a supporting tool and to stably keep an opened state by annularly connecting and folding thin and long paper, attaching the bag for extraction to the inside and folding the part to the inside in two stages by a fold provided on an upper part beforehand. SOLUTION: This beverage bag 1 is composed of the supporting tool 3 and the bag 2 for extraction and the supporting tool 3 is formed by folding back the upper half of a sheet 4, stacking it on a lower half and thermally melt- sticking a tab for sticking. Then, the bag 2 is welded to the inner side 16 of the supporting tool 3. At the time of use, the part of the fold 9 at the upper part of both sides of the supporting tool 3 is pushed in downwards and the part continuous to the front and back sheets 4 is folded back like a hinge with the fold 9 as a shaft. Also, the tucks of the two stages are formed at the part of the two triangles constituted of the folds 6-8 as well accompanying it. Then, such a supporting tool 3 is placed on the edge of a coffee cup or the like, the appropriate amount of coffee grains are put in the bag 2, hot water is poured and contents are extracted.

    • PURPOSE:To effect a full extraction of the material to be extracted in a relatively large extraction space and improve dewatering of the extract by providing a tetrahedral container formed of a water-permeable sheet, the material to be extracted received in this container and a hanging string extending from the outer peripheral surface thereof. CONSTITUTION:A piece of a rectangular water-permeable sheet is folded along its center line A, both the side edges B and C of the sheet are bonded together to form a joining part D and the bottom edges thereof are bonded together to form a joining part E. This bag-like body is filled with the material to be extracted in a desired amount and both the edges F and G of an opening part thereof are pulled apart and put back together in such a way that the middle points H and J of the edges F and G form the both ends of this overlapping part, which is then bonded together to form a joining part K. From a piece of water-permeable sheet, therefore, a tetrahedral container having the four sides is obtained. Furthermore, one end of a hanging string 9 is attached to a predetermined attaching point 6 of the container. This permits a rapid and efficient extraction.

    • PURPOSE:To prevent an extracted material from leaking out by extending the folded part of a bag body opening and by folding back the front and reverse sides of the extension in alternately opposite directions and combining them with each other. CONSTITUTION:Both planar parts of a bag body 15 have extensions protruding from respective opening edges to form the planar parts 16 of these extensions and one of the planar parts 16 is folded back to the outside of the bag body to form a folded part 18. Both side edges 19 of these parts are bound and fixed to the continuous marginal parts 2a, 3a of the bag body and the end parts of the part folded back to the outside is further folded back to the outside of the bag body. Both side edges of these parts are further bound and fixed to the continuous marginal parts of the bag body to form the outermost side folded part 20. After a desired extracted material has been put into the bag body and the extension tip 21 of the extended planar part 16 has been inserted between the outside folded part 18 and outermost side folded part 20, the outermost side folded part 20 is folded from the planar part 13 side to the planar part 12 side so that the bag body can be closed and the extracted material can be prevented from leaking out of the extraction bag.
