  FIG. 1 shows an embodiment of a bag for extracting a beverage according to the present invention. This bag for extracting a beverage with preference (hereinafter sometimes abbreviated as “bag for extraction”) 1 is an outer bag. An inner bag 3 is housed inside 2. The outer bag 2 and the inner bag 3 are made of a flexible sheet material having filterability, and the raw material can be woven fabric, knitted fabric, non-woven fabric, paper, or a composite material thereof. The sheet material of the inner bag 3 is preferably a material (filtering speed is higher) that has better filterability than the sheet material of the outer bag 2.

  The material of the outer bag 2 and the inner bag 3 has a subtle influence on the flavor of the obtained palatability drink. For example, in order to brew coffee with excellent fragrance and richness, it is desirable that the coffee material is one that does not leak coffee fine particles into the liquid, and further absorbs fats and oils contained in the coffee liquid. It is preferable that the oil film does not float on the surface of the cup after being removed.

  The material of the sheet material is as described above and is not particularly limited. However, as a material that can enhance the leakage of fine particles and the adsorptivity of the oil film, for example, an ultrafine fiber having a fiber diameter of about 0.5 μm or less. Nonwoven fabrics containing fibers are preferred. The ultrafine fiber can be produced from a thermoplastic polymer by, for example, a melt blow method. As the kind of thermoplastic polymer, polyester, polylactic acid, polypyropylene, polyethylene and the like can be used. It is also possible to use a composite nonwoven fabric composed of such a superfine fiber nonwoven fabric layer and a support layer made of a normal thickness fiber, and has high mechanical properties for filter fabric as well as filterability and extractability. There is a characteristic that can impart. In addition, as a material of the inner side bag 3, nonwoven fabrics or textiles, such as TB, SB, a mesh, can be used, for example, As a material of the outer side bag 3, coffee miraclon (brand name) can be used, for example. .

  A support sheet 5 made of paper with a waist is attached to the front and back outer surfaces of the outer bag 2. The term “having waist” means that it has a certain degree of rigidity and elasticity, such as Kent paper, and also has a plasticity that can be held in its shape when deformed.

  The support sheet 5 is formed with a gate-shaped edge composed of an upper edge portion 6 and left and right edge portions 7 and 8, and a center piece 9 is formed from the left and right center portion of the upper edge portion 6 toward the lower side. . Intermediate pieces 10 and 11 are formed on the left and right sides of the central piece 9. The intermediate pieces 10, 11 are integrated with the central piece 9 at a lower portion of the lower end portion relative to the fold line 12. This fold line 12 is for elastically bending and is not perforated.

A frame-shaped piece 13 is formed outside the intermediate pieces 10 and 11 so as to surround the intermediate pieces 10 and 11. The frame-shaped piece 13 includes left and right vertical portions 14 and 15 and a horizontal portion 16 that connects the lower ends of the left and right vertical portions 14 and 15, and the upper ends of the vertical portions 14 and 15 are respectively inward. The bent end portions 14a and 15a are connected to the upper end portions of the intermediate pieces 10 and 11, respectively. A fold line 17 made of a perforation is formed at the connecting portion. The upper and lower intermediate portions of the vertical portions 14 and 15 of the frame-shaped piece 13 are formed with ridges 18 and 19 projecting toward the intermediate pieces 10 and 11, and can be bent inward and outward by a fold line 20 made of a perforation. It is like that. The flanges 18 and 19 are for assisting engagement with a cup or the like.

  The support sheet 5 has an upper edge portion 6, left and right edge portions 7, 8, a center piece 9, and a portion (a portion below the folding line 12) that extends to the left and right of the lower end portion of the center piece 9. It is bonded to the outer surface of the outer bag 2. The left and right intermediate pieces 10 and 11 can be bent outward by a fold line 12, and the frame-like piece 13 can be elastically extended outward from the upper end portions of the intermediate pieces 10 and 11. is there. Although the connecting portion of the frame-shaped piece 13 can be slightly bent by the bending line 17, the bending line 17 is not always necessary.

  The inner bag 3 excellent in filterability is formed as a sealed bag without an opening, and a raw material (powder) 40 for extracting a tasteful beverage is accommodated therein. The inner bag 3 is partially bonded to the inner surface of the outer bag 2 (the bottom in FIG. 1), and is integrated with the outer bag 2 at that portion.

  When this extraction bag 1 is used, the lateral portions 16 of the frame-shaped pieces 13 are raised from the support sheets 5 on the front and back sides of the outer bag 2 and the left and right frame-shaped pieces 13 are pulled outward. Then, the portion not bonded to the outer bag 2 is pulled out outward, and as shown in FIGS. 2, 3, and 4, the intermediate piece 10 (11) and the frame-shaped piece 13 are substantially inverted in a side view. A shaped engaging portion 30 is formed. The frame-shaped piece 13, the intermediate pieces (10), (11) and the like constitute the handle 45. 3 and 4 are schematically shown, and the sheet material is shown thick.

  When the handle 45 is pulled out from the support sheets 5 on both sides of the outer bag 2 in this manner, the engaging portions 30 that are formed on the handle 45 and are opened downward are respectively hooked on the edges of the cup 50. That is, the edge of the cup 50 is fitted inside the inverted V-shaped engaging portion 30. Since the engaging portion 30 is simply pulled out from the support sheets 5 on both the front and back sides of the outer bag 2 and hung on the edge of the cup, the attachment of the extraction bag 1 to the cup 50 is simple.

  When the extraction bag 1 is attached to the cup, hot water is poured into the space portion 35 between the outer bag 2 and the inner bag 3. Then, a beverage is extracted from the palatable beverage raw material powder inside the inner bag 3, passes through the outer bag 2 having filterability, and flows out of the outer bag 2. In this way, the extracted palatable beverage is filled in the cup. When the extraction is sufficiently advanced, the extraction bag 1 may be taken out of the cup and enjoyed with the beverage.

  Next, a production material used for manufacturing the extraction bag 1 will be described. As shown in FIG. 5, the extraction bag manufacturing material 100 is formed by superposing an outer sheet 102 for forming the outer bag 2 and an inner sheet 103 for forming the inner bag 3. The outer sheet 102 and the inner sheet 103 are partially bonded. As shown in FIG. 6, this bonding portion may be bonded at a portion (portion that becomes the bottom of the extraction bag) 110 near the center line L in the longitudinal direction, or as shown in FIGS. 7 (a) and 7 (b). Thus, you may adhere | attach in the part 111 which shifted | deviated to one side from the centerline of the outer side bag 2. FIG. The size of the bonding portion may be bonded on a surface having a predetermined width, or may be bonded in a thin line shape, or may be bonded in a continuous dot shape like a perforation. In short, it is sufficient that the inner sheet 103 is integrated with the outer sheet 102 so as not to be separated during handling. From the viewpoint of strength, it is preferable to bond the surfaces with a predetermined width. In some cases, as shown in FIG. 8, the inner sheet 103 may be divided into two at the center, and bonded to the outer sheet 102 at each of the divided end portions 112.

  A pair of support sheets 5 for forming the grip 45 is attached to the outer surface of the outer sheet 102, that is, the surface on which the inner sheet 103 is not superimposed, at a predetermined interval. The pair of support sheets 5 are attached symmetrically across the center line L in the longitudinal direction of the outer sheet 102. The distance between the pair of support sheets adjacent to each other in the lateral direction is set so that each of them becomes the width of the extraction bag 1 when separated by a cutting line S perpendicular to the center line L at the center of the distance. Yes.

  Since the extraction bag manufacturing action material 100 is in a state in which a plurality of extraction bags 1 are arranged, in use, the extraction bag manufacturing material 100 is folded at the center line L so that the outer sheet 102 faces outside. And it cut | disconnects by cut | disconnecting (melting | fusing) the cut | interruption S in the intermediate part of the mutually adjacent support sheets 5, and it divides | segments into one for each of the bags 1 for each extraction by fuse | melting the both-sides part of this cut part . It is convenient to perform the fusing and fusing by using an ultrasonic horn and an anvil and sandwiching the material 100 therebetween.

  Incomplete products for extraction one by one from the production material 100 (the inner bag 3 formed by the inner sheet 103 is accommodated inside the outer bag 2 formed by the outer sheet 102, and the inner bag 3 has an upper end portion. Is cut out), a predetermined amount of the material (powder) 40 for extracting a palatability beverage is placed inside the inner bag 3 (the upper end is in the open state) formed by the inner sheet 103. The opening (upper end) 3a is closed. This occlusion can also be performed using ultrasonic waves. Thereby, the target extraction bag 1 is obtained.

  This extraction bag manufacturing material 100 is compact and convenient for storage, transportation, etc. because all the necessary components (excluding raw material powder) are integrated into the extraction bag 1. The production of the bag 1 is very easy. If this extraction bag making raw material sheet 50 is prepared, an extraction bag for any palatable beverage can be easily and quickly created, which is economical for the patronage beverage provider, It is also convenient. Depending on the case, you may provide the thing divided | segmented into the individual bag before putting the raw material 40 for extraction as a material of the bag for extraction.

Alternatively, a composite sheet obtained by laminating a support sheet having waist at regular intervals on the outer surface side of the outer sheet raw fabric having filterability, and laminating the outer sheet and an inner sheet having excellent filterability, The composite sheet is supplied from the entrance of the coffee filling machine in a state of being combined beforehand. Here, when a predetermined amount of palatable beverage raw material particles is injected into the inner sheet of the composite sheet, the composite sheet is melted and cut in a direction transverse to the vertical direction of the specified interval in the length direction. An extraction bag is formed.

In addition, along with the above operation, since the seal between the inner sheet and the outer sheet is formed at both end portions of the extraction bag, the cross section is inverted by causing the supporting sheets attached to both the front and back surfaces of the outer sheet. The V-shaped handle is formed and can be used as an extraction bag. Thus, the palatable beverage extraction bag making method and the extracting bag making raw material sheet that can directly obtain the palatable beverage extracting bag in one step from the raw material sheet are also included in the present invention. .
