Description
Drip Bag Aid and Coffee Extraction Method 【0001】 The present invention relates to a drip bag aid for assisting the operation of extracting coffee from a drip bag into a container, and a coffee extraction method using the same. 【0002】 A drip bag (sometimes referred to as a "drip pack") that individually wraps one cup of coffee powder in a liquid-permeable paper (filter) and fixes it to a cup to brew coffee can brew authentic coffee simply without using tools such as a dripper. Therefore, many products are sold and loved. 【0003】 The drip bag is installed above the cup for brewing coffee, and coffee is brewed by pouring hot water from above onto the coffee powder in the filter. There are multiple types of drip bags depending on the method of installation on the cup. A hook-type drip bag that uses a hook as a member (support piece) that is attached to the outside of the filter and supports the drip bag body when installed on the cup is installed on the cup by hanging the hook on the edge of the cup. The hook-type drip bag includes a type that fixes the drip bag at two points (hereinafter referred to as the "two-point hook type"), such as the X-type and arch-type, and a type that fixes it at three points (hereinafter referred to as the "three-point hook type"), such as the VFR type. There is also a type (hereinafter referred to as the "overlay type") in which the drip bag is installed on the cup by placing a support piece on the cup, such as a conical drip bag. 【0004】 As described above, the drip bag can brew coffee without using other tools. However, in order to use the drip bag more comfortably, tools for assisting the extraction of coffee by the drip bag have been proposed. 【0005】For example, Patent Document 1 proposes a drip coffee maker comprising a mounting plate that can be placed on a cup and a container that can accommodate a drip bag. In the drip coffee maker of Patent Document 1, the drip bag is housed in the container, so the presence of the bottom surface of the container prevents the drip bag from sinking into the cup, and the coffee grounds inside the drip bag are not immersed in the extracted coffee. In addition, in the drip coffee maker of Patent Document 1, a gap is formed between the rim of the cup and the peripheral edge of the mounting member, allowing the coffee poured into the cup to be viewed through this gap. 【0006】 Patent Document 2 proposes a coffee drip bag holder in which a cylinder (extraction cylinder) is placed on a base (holder base) that covers the top surface of a cup. In the holder of Patent Document 2, the drip bag's hook is attached to the cylinder to extract the coffee, so the drip bag is held above the extracted coffee and is not immersed in it. 【0007】 Patent Document 3 proposes a coffee drip stand for a coffee drip filter, in which the coffee drip filter (drip bag) is placed on top of the cup. In the drip stand of Patent Document 3, the coffee drip filter is placed in a cylindrical drip stand body that is taller than the vertical length of the coffee drip filter, and one end of a horizontal bar provided on the lower side of the drip stand body is hooked onto the rim of the cup, thereby positioning the drip stand on top of the cup, so that the coffee drip filter does not get submerged in the coffee. In addition, in the drip stand of Patent Document 3, the presence of the horizontal bar creates a gap between the drip stand body and the cup, allowing the amount of brewed coffee to be checked. 【0008】 Utility Model Registration No. 3197073, Japanese Patent Publication No. 2007-159897, Japanese Patent Publication No. 2024-61117 【0009】However, the devices proposed in Patent Documents 1 to 3 can only accommodate one drip bag. Since 8 to 12 grams of coffee grounds are commonly used in one drip bag, and the appropriate amount of coffee extracted from this quantity is considered to be 100 to 140 cc, extracting a larger quantity of coffee, or extracting a stronger coffee from that quantity, requires switching between multiple drip bags, which becomes a time-consuming process. When making iced coffee using a drip bag, the process typically involves cooling conventionally prepared hot coffee in a refrigerator or pouring hot coffee into a cup filled with ice. In the latter case, a stronger coffee is considered more suitable, and there is a need for a simple way to produce large quantities of strong coffee, especially for making large batches in advance. 【0010】 The present invention has been made in accordance with the circumstances described above, and the object of the present invention is to provide a drip bag auxiliary device and a coffee extraction method using the same that can easily expand the range in which the amount and strength of the extracted coffee can be changed when brewing coffee using a drip bag. 【0011】 The inventors of this invention have conducted extensive research to solve the above problems and have found that the following invention is suitable for the above purpose, leading to the present invention. That is, the present invention relates to the following invention. 【0012】<1> A drip bag assist device that assists in the extraction of coffee from the drip bag into the container, comprising: an installation section having a pair of sides extending parallel to the longitudinal direction on the upper surface, with a pair of support pieces attached to both sides of the drip bag at the locations of the pair of sides, thereby enabling the installation of a plurality of the drip bags in a row along the longitudinal direction; and a base section connected to the installation section and placed on the opening edge of the container, wherein a through hole is formed at the location where the installation section and the base section are joined, <2> A drip bag assist device for assisting the extraction of coffee from a drip bag to a container, wherein the drip bag has a pair of hooks attached to both sides, and comprises: an installation part having a pair of sides extending parallel to the longitudinal direction on its upper surface, to which the pair of hooks can be attached, thereby allowing multiple drip bags to be installed in a row in the longitudinal direction; and a base part connected to the installation part and placed on the opening edge of the container, wherein a through hole is formed at the location where the installation part and the base part are joined. <3> The drip bag assist device according to <1> or <2>, wherein the base part comprises a flat plate part connected to the installation part and being flat, and a leg part extending vertically downward for a predetermined length from the periphery of the flat plate part. <4> The drip bag assist device according to <1> or <2>, wherein the base portion comprises a flat plate portion that is joined to the installation portion and is in the shape of a flat plate, and a leg portion that extends vertically downward for a predetermined length from a position between the periphery and the center of the flat plate portion. <5> The drip bag assist device comprises an installation portion that is placed on the opening edge of a container and has a pair of sides that extend parallel to the longitudinal direction on the upper surface, and a pair of support pieces of a drip bag which have a pair of support pieces attached to both sides at the location of the pair of sides, thereby enabling the installation of a plurality of the drip bags in the longitudinal direction, and a through hole is formed in the lower part of the installation portion to assist in the extraction of coffee from the drip bag into the container.<6> A drip bag assist device for assisting the extraction of coffee from a drip bag having a pair of hooks attached to both sides into a container, the drip bag assist device having an installation part that is placed on the opening edge of the container and has a pair of sides extending parallel to the longitudinal direction on its upper surface, and the pair of hooks can be attached to the locations of the pair of sides to install a plurality of the drip bags in a row in the longitudinal direction, and a through hole is formed in the lower part of the installation part. <7> The drip bag assist device according to <5> or <6>, further comprising a leg portion extending vertically downward for a predetermined length from the edge located in the longitudinal direction at the lower part of the installation part. <8> The drip bag assist device according to <5> or <6>, further comprising a leg portion extending vertically downward for a predetermined length from a position between the periphery and the center of the lower part of the installation part. <9> The drip bag assist device according to any one of <1> to <8>, further comprising a projection portion extending vertically downward for a predetermined length from the periphery of the through hole. <10> The drip bag auxiliary device according to any one of <1> to <9>, wherein the mounting section is capable of mounting two of the drip bags side by side. <11> A coffee extraction method for extracting coffee from the drip bag using the drip bag auxiliary device according to any one of <1> to <10>. 【0013】 According to the drip bag auxiliary device and coffee extraction method of the present invention, since the installation part can accommodate multiple drip bags, it is possible to broaden the range in which the amount and strength of the extracted coffee can be changed compared to when extracting coffee using a single drip bag, without having to change the drip bag. 【0014】This is a perspective view showing an example of a drip bag support device according to the present invention (first embodiment).

This figure shows the drip bag support device of the seventh embodiment, where (A) is a plan view and (B) is a cross-sectional view. This figure shows an example of when a drip bag is installed in the drip bag support device of the seventh embodiment. 【0015】The present invention relates to a drip bag assist device that allows multiple drip bags to be used simultaneously when brewing coffee using drip bags. The first drip bag assist device according to the present invention comprises an installation part for installing drip bags and a base part connected to the installation part and placed on the rim (opening rim) of a container such as a cup into which the coffee extracted from the drip bag is poured, making it possible to install multiple drip bags side by side on the installation part. In the present invention, the target drip bag is a drip bag in which a pair of support pieces are attached to both sides. Here, "support piece" is a general term for a member provided on the outside of the filter to support the drip bag body against the opening rim of the container, and specific examples include a hook that hangs on the rim of the cup (hook type), and a wing or ring-shaped support part that is placed on the rim of the cup (top-on type). For example, in the case of a two-point hook type drip bag, which uses hooks as support pieces to secure the drip bag at two points, the installation part has an opening for inserting the drip bag and a side surface on which a pair of hooks attached to both sides of the filter can be hung. After opening the filter containing the coffee grounds, the hooks are opened and multiple drip bags (for example, two) that are ready to be hung on the side surface of the installation part and ready to be poured with hot water are inserted through the opening and stored inside. The drip bag support device according to the present invention can also be used with three-point hook type drip bags, top-loading type drip bags, etc., and it is also possible to use a mix of different types of drip bags. 【0016】 The second drip bag assist device according to the present invention has a mounting part but no base. In other words, the mounting part for placing the drip bag is shaped to rest on the rim of the container. Because there is no base, the drip bag assist device does not cover the entire rim of the container, creating a gap in the horizontal direction, through which the amount of coffee being poured into the container can be checked. 【0017】The drip bag assist device according to the present invention has through holes formed at the point where the mounting part and the base part are joined in the first drip bag assist device, and at the lower part of the mounting part (the part that contacts the edge of the container) in the second drip bag assist device, so that the coffee extracted from the drip bag is injected into the container. In the present invention, the height of the mounting part may be either a height such that the lower end of the drip bag is located inside the mounting part of the drip bag assist device when the drip bag is placed there (hereinafter referred to as "long height"), or a height such that the drip bag does not fit inside the mounting part (hereinafter referred to as "short height"). When the height of the mounting part is long height, the coffee dripping from the drip bag passes through the through holes and is injected into the container. When the height of the mounting part is short height, the through holes are large enough to allow the lower part of the filter of the drip bag to pass through, and the coffee is extracted with the lower part of the filter protruding from the drip bag assist device. One through hole can be formed, or any number of through holes, equal to the number of drip bags that can be installed. However, in order to prevent the extracted coffee from leaking out of the container into which the coffee is poured when the drip bag is being extracted, it is preferable that the through-holes are formed so that all of them are located inside the rim of the container when the drip bag support is installed on the container. Since containers come in various sizes, and consequently the rims also come in various sizes, it is also possible to prepare multiple types of drip bag support devices with different sizes and arrangements of through-holes, for example, so that the drip bag support device can be selected according to the size of the container. It is also possible to prepare multiple sizes of the base or lower part of the mounting section that rests on the rim of the container so that it can be selected according to the size of the container. 【0018】In this invention, since multiple drip bags can be set up simultaneously, the range of how to change the amount and strength of the brewed coffee can be easily expanded compared to when brewing coffee using a single drip bag. For example, if you want to brew more coffee than the appropriate amount brewed with a single drip bag, or if you want to brew stronger coffee, you can easily do so without having to switch between multiple drip bags. Since hot water can be poured into multiple drip bags at the same time, the amount of hot water being poured can be checked, and the hot water can be poured more evenly into each drip bag compared to when switching between drip bags. 【0019】 In this invention, it is possible to provide a projection that extends vertically downward for a predetermined length from the periphery of the through hole. By providing the projection, it is possible to suppress the possibility that coffee extracted from the drip bag will leak out of the container via the drip bag support. 【0020】 In the first drip bag support according to the present invention, the base portion can be comprised of a flat plate portion that is joined to the installation portion, and legs that extend vertically downward (in the opposite direction to the direction in which the installation portion is located) for a predetermined length from the periphery of the flat plate portion. The legs can also be formed to extend vertically downward for a predetermined length from a position between the periphery and the center of the flat plate portion, rather than from the periphery of the flat plate portion. In the second drip bag support according to the present invention, the legs can be provided at the bottom of the installation portion. By providing the legs, it is possible to prevent the drip bag support from sliding and falling from the container, and if the drip bag support has a protrusion, the legs can act as legs to stabilize the drip bag support when the drip bag support alone is placed on a flat surface such as a table. 【0021】 Embodiments of the present invention will be described below with reference to the drawings. In each drawing, the same components are denoted by the same reference numerals, and their descriptions may be omitted. Furthermore, the structures, shapes, etc., described below are illustrative, and the present invention is not limited to these. 【0022】An example of a drip bag support device according to the present invention (first embodiment) is shown in Figures 1 to 3. The drip bag support device 1 is shaped to accommodate two two-point hook type drip bags and includes an installation part 10 and a base part 20, with the installation part 10 being tall. The installation part 10 and the base part 20 are connected, and two through holes 31 and 32 are formed at the joint between the installation part 10 and the base part 20. Figure 1 is a perspective view of the drip bag support device 1. Figure 2(A) is a plan view of the drip bag support device 1, and Figure 2(B) is a cross-sectional view of the drip bag support device 1 shown in Figure 2(A) along line A-A. Figure 3 is a perspective view of the drip bag support device 1 when drip bags 40 (drip bags 41 and 42) are installed. In Figures 1 and 3, as indicated by the arrows, the upper, lower, right, and left sides are the "top," "bottom," "right," and "left" of the drip bag support device 1, respectively, and the front and rear sides are the "front" and "rear" of the drip bag support device 1, respectively. The same applies to Figures 4, 7, 9, and 13, which show examples of drip bag support devices in the second, third, fifth, and seventh embodiments. 【0023】 The mounting section 10 has a shape resembling an inverted truncated square pyramid with slightly rounded vertices and hypotenuses, and its top surface is an open surface. The drip bag 40 is inserted into the interior of the mounting section 10 from the top surface, which is the open surface. 【0024】 The upper surface of the installation section 10 is rectangular in shape with an arc at its apex. As shown in Figure 3, the drip bags 41 and 42 are installed side by side by hanging the hooks attached to both sides of the drip bag 40 on the longer side (the side extending in the front-to-back direction in Figure 3) of the upper surface (hereinafter referred to as the "long edge"). Therefore, the long side of the upper surface is long enough to accommodate the two hooks 411 and 421 that each of the drip bags 41 and 42 has, for example, about 12 cm. The short side of the upper surface (the side extending in the left-to-right direction in Figure 3) is long enough such that the opening of the filter becomes roughly rectangular when the hooks of the opened drip bag 40 are hung on the long edge, for example, about 6 cm. 【0025】The lower surface of the mounting section 10 has a similar shape to the upper surface, but is slightly smaller. For example, if the lengths of the long and short sides of the upper surface are approximately 12 cm and 6 cm, respectively, the lengths of the long and short sides of the lower surface are approximately 10 cm and 4 cm. As shown in Figure 2, when the drip bag auxiliary device 1 is viewed from above, the lower surface of the mounting section 10 is formed so that its center overlaps with the upper surface and it is located inside the upper surface. 【0026】 The mounting section 10 has four sides (front, rear, right, and left) that are connected to the top and bottom surfaces. The front and rear surfaces of the mounting section 10 are in contact with the short sides of the top and bottom surfaces, and the right and left sides are in contact with the long sides of the top and bottom surfaces. The slanted edges of each side (the edges extending vertically in Figure 1) are gently curved outwards in a convex shape. Since the mounting section 10 is tall, the height of the sides (the vertical length in Figure 1) is such that when the drip bag 40 is placed on the mounting section 10, the lower end of the drip bag 40 does not come into contact with the bottom surface of the mounting section 10, or if it does, only a part of it comes into contact. For example, it is about 6 cm. Note that the slanted edges of the sides of the mounting section 10 do not have a convex curved shape, but may be straight. 【0027】The base portion 20 has a cylindrical shape with an open bottom. That is, as shown in Figure 2, the base portion 20 is composed of a disc-shaped flat plate portion 21 that is joined to the installation portion 10, and leg portions 22 that extend vertically downward (downward in the vertical direction) from the periphery of the flat plate portion 21. The upper surface of the flat plate portion 21 and the lower surface of the installation portion 10 are joined so that their respective centers overlap. The drip bag assist device 1 is placed on a container such as a cup into which coffee is poured, and the drip bag assist device 1 is placed on the cup by placing the base portion 20 so as to cover the entire rim of the cup. Therefore, the upper surface of the flat plate portion 21 is larger than the rim of the cup, for example, the diameter of the upper surface is about 12 cm. Cups come in various sizes, and the rim sizes also vary, so it is possible to prepare multiple types of drip bag assist devices 1 with different base portion sizes so that the appropriate drip bag assist device 1 can be selected according to the size of the cup. As described above, the base portion 20 is placed on the rim of the cup, and the presence of the legs 22 prevents the drip bag support 1 from sliding and falling out of the cup. The height of the legs 22 (length in the vertical direction in Figure 1) is, for example, about 1 cm. 【0028】 As shown in Figure 2(A), circular through-holes 30 (through-holes 31 and 32) are formed at the joint between the mounting section 10 and the base section 20, penetrating both the mounting section 10 and the base section 20. In the drip bag assist device 1, when two drip bags 41 and 42 are placed on the mounting section 10, the through-holes 31 and 32 are formed at positions opposite the lower ends of each drip bag. By forming the through-holes 30 in these positions, the coffee dripping from the drip bag passes through the through-holes 30 and is injected into the cup. In the drip bag assist device 1, the entire lower surface of the mounting section 10 is joined to the upper surface of the flat plate section 21, so the through-holes 30 are formed to match the size of the lower surface of the mounting section 10. For example, if the lengths of the long side and short side of the lower surface are approximately 10 cm and 4 cm, respectively, the diameter of the through-holes 30 is approximately 3 cm. The number of through-holes 30 can be one or three or more, and their shape is not limited to circles; they can be squares or other shapes. If there is only one through-hole 30, the entire lower surface of the installation part 10 may be the through-hole 30. 【0029】 The drip bag support 1 is made of a material that has sufficient strength to maintain stability even when hot water is poured into the two installed drip bags, heat resistance to withstand boiling water, and a weight that does not burden the cup on which the drip bag support 1 is placed. For example, the drip bag support 1 is made of stainless steel, AS (acrylonitrile styrene) resin, PP (polypropylene) resin, polycarbonate, heat-resistant glass, copper, porcelain, ceramic, paper (preferably water-resistant and heat-resistant), etc. The thickness of the drip bag support 1 is determined by the material, taking into consideration the strength, heat resistance, weight, etc. For example, if it is made of AS resin, the thickness of the drip bag support 1 is 1 to 2 mm. The thickness of the installation part 10 and the base part 20 may differ, and the materials may also differ. 【0030】 As a material for the drip bag auxiliary device 1, at least the base portion 20 is made of a permeable material, such as AS resin or PP resin. If the base portion 20 is made of a permeable material, the base portion 20 is also permeable, and the amount of coffee poured into the cup can be checked through the base portion 20 while the coffee is being brewed. 【0031】 This section describes a method for brewing coffee using a drip bag aid 1 with the structure described above. 【0032】 First, the drip bag support device 1 is placed on the cup so that the base portion 20 rests on the rim of the cup from which the coffee will be brewed. Then, the filters of the drip bags 41 and 42 are opened, and the hooks 411 and 421 attached to both sides of each drip bag are opened and hung on the long edges (right side and left side) of the mounting portion 10, so that the drip bags 41 and 42 are aligned in the longitudinal direction (front-to-back direction in Figure 3) of the mounting portion 10. Alternatively, the drip bags 41 and 42 may be placed on the drip bag support device 1, and then the drip bag support device 1 may be placed on the cup. 【0033】A suitable amount of hot water is poured alternately onto the drip bags 41 and 42, which are placed on the drip bag assist device 1. Since the drip bags 41 and 42 are placed side by side, a roughly equal amount of hot water can be poured into both. If the base portion 20 is permeable, the amount of hot water poured onto the drip bags 41 and 42 is adjusted while checking the amount of coffee being poured into the cup through the base portion 20. 【0034】 Once the appropriate amount of coffee has been poured into the cup and the dripping from the drip bag assist device 1 has finished, remove the drip bag assist device 1 from the cup. In this case, you may also remove the drip bags 41 and 42 from the drip bag assist device 1 first, and then remove the drip bag assist device 1 from the cup. 【0035】 As described above, the drip bag assist device 1 can accommodate two drip bags 41 and 42, so compared to using a single drip bag to brew coffee, the range of adjustment for the amount and strength of the brewed coffee is wider, allowing for the brewing of coffee that better suits the user's preferences. 【0036】 The shape of the mounting section 10 is not limited to the shape described above; other shapes are acceptable as long as multiple drip bags can be installed. The shape of the base section 20 is also not limited to the shape described above; other shapes are acceptable as long as it connects to the mounting section 10 and can be placed on a cup, and it does not have to be a shape that covers the entire rim of the cup. The legs 22 do not have to be a shape that extends vertically downward from the entire periphery of the flat plate section 21, but rather a shape that extends from multiple points within the periphery, as long as the drip bag support device 1 alone does not become unstable when placed on a flat surface, and the legs 22 are not even necessary. In addition, although the drip bag support device 1 is designed to accommodate a two-point hook type drip bag, it may also be designed to accommodate other types of drip bags, such as a three-point type or a top-loading type drip bag. 【0037】 A second embodiment of the present invention will now be described. In the first embodiment, the installation part 10 is tall, but in the present invention, it is also possible to use an installation part that is short, that is, an installation part in which the lower end of the drip bag does not fit when the drip bag is installed. 【0038】 Figures 4 to 6 show an example of a drip bag support device with a short-height mounting section (second embodiment). Similar to drip bag support device 1, drip bag support device 2 is shaped to accommodate two two-point hook type drip bags and is equipped with a connecting mounting section 50 and a base section 60, with the mounting section 50 being short-height. Two through holes 71 and 72 are formed at the joint between the mounting section 50 and the base section 60. Figure 4 is a perspective view of drip bag support device 2, Figure 5 is a plan view of drip bag support device 2, and Figure 6 is a front view when a drip bag 40 is installed on drip bag support device 2. 【0039】 The mounting section 50, like the mounting section 10 of the drip bag support device 1, has a shape that is like an inverted truncated square pyramid with the vertex and hypotenuse slightly rounded, but the height of the sides (length in the vertical direction in Figure 4) is shorter than the height of the sides of the mounting section 10. That is, as shown in Figure 6, the height of the sides of the mounting section 50 is such that when the drip bag 40 is placed on the mounting section 50, the bottom of the drip bag protrudes below the drip bag support device 2, for example, about 2 cm. In line with the shorter height of the sides, the bottom surface of the mounting section 50 is slightly larger than the bottom surface of the mounting section 10, for example, the lengths of the long side (side extending in the front-to-back direction in Figure 4) and short side (side extending in the left-to-right direction in Figure 4) of the bottom surface are about 11 cm and about 5 cm, respectively. The top surface of the mounting section 50 is approximately the same size as the top surface of the mounting section 10, for example, the lengths of the long side and short side of the top surface are about 12 cm and about 6 cm, respectively. 【0040】 The base portion 60 has a cylindrical shape with an open bottom, similar to the base portion 20 of the drip bag auxiliary device 1. 【0041】The through holes 70 (through holes 71 and 72) formed at the location where the installation part 50 and the pedestal part 60 are joined are square in shape. When the drip bag 40 is installed on the installation part 50, the lower end of the drip bag 40 passes through the through hole 70 and reaches below the drip bag auxiliary tool 2. Therefore, the through hole 70 is sized such that the lower part of the drip bag 40 can pass through. For example, the through hole 70 is a square with a side length of about 4 cm. Note that as long as the lower part of the drip bag 40 can pass through, the number of through holes 70 can be one, and the shape does not have to be square; other shapes are also acceptable. 【0042】 In this way, when the lower part of the drip bag 40 installed on the installation part 50 protrudes below the drip bag auxiliary tool 2, in the process of extracting coffee into the cup, it becomes possible to immerse the lower part of the filter in the extracted coffee. By immersing the lower part of the filter in the coffee, it becomes possible to extract strong coffee, etc. Therefore, the use of the drip bag auxiliary tool 2 is suitable for making iced coffee, etc., which is said to be suitable for strong coffee. Note that similar to the case of the drip bag auxiliary tool 1, the shapes of the installation part 50 and / or the pedestal part 60 are not limited to the above shapes, and other shapes are also acceptable. 【0043】 The third embodiment of the present invention will be described. The drip bag auxiliary tools 1 and 2 in the first and second embodiments are configured to be able to install two drip bags, but the drip bag auxiliary tool according to the present invention can also be shaped to be able to install three or more drip bags. 【0044】 Fig. 7 shows an example of a drip bag auxiliary tool (third embodiment) that can install four drip bags. The drip bag auxiliary tool 3 is shaped such that four two-point hook type drip bags can be installed. It includes a short-height installation part 80 similar to the drip bag auxiliary tool 2 in the second embodiment, and a pedestal part 90 connected to the installation part 80. A through hole (not shown) is formed at the location where the installation part 80 and the pedestal part 90 are joined. Fig. 7 is a perspective view when four drip bags 41, 42, 43, and 44 are installed on the drip bag auxiliary tool 3. 【0045】The installation part 80 has a short height similar to the installation part 50 of the drip bag accessory 2, but in order to be able to install four drip bags 41 to 44, the length in the longitudinal direction (front - rear direction in FIG. 7) is longer than that of the installation part 50. For example, the height of the side surface of the installation part 80 (the length in the up - down direction in FIG. 7) is about 2 cm, and the lengths of the long sides of the upper surface and the lower surface (the sides extending in the front - rear direction in FIG. 7) are about 24 cm and about 23 cm respectively. The lengths of the short sides of the upper surface and the lower surface (the sides extending in the left - right direction in FIG. 7) are substantially the same as those of the installation part 50, for example, about 6 cm and about 5 cm respectively. 【0046】 The pedestal part 90 has the shape of a cylinder with an open bottom surface, similar to the pedestal part 60 of the drip bag accessory 2, but it is larger than the pedestal part 60. For example, the diameter of the upper surface of the flat plate part of the pedestal part 90 is about 25 cm. 【0047】 Four through - holes are formed at the location where the installation part 80 and the pedestal part 90 are joined, according to the number of drip bags that can be installed in the installation part 80. For example, they have a square shape similar to the through - hole 70 of the drip bag accessory 2, and are sized such that the lower part of the drip bag can pass through (for example, the length of one side is about 4 cm). 【0048】 The drip bag accessory 3 with such a shape is a bit large for use in an ordinary cup, and the lower part of the drip bag protrudes below the drip bag accessory 3. So, for example, it is suitable for use when making and leaving iced coffee in a container with a large opening edge. Note that, similar to the case of the drip bag accessory 2, the shapes of the installation part 80 and / or the pedestal part 90 are not limited to the above - mentioned shapes, and other shapes are also possible. The number and / or shape of the through - holes are not limited to the above. 【0049】 The fourth embodiment of the present invention will be described. In the present invention, it is possible to provide a protrusion that extends vertically downward from the peripheral edge of the through - hole 30 with respect to the drip bag accessory 1 in the first embodiment. 【0050】An example of a drip bag support device equipped with a protrusion (fourth embodiment) is shown in Figure 8. Similar to the drip bag support device 1, the drip bag support device 4 is shaped to accommodate two two-point hook type drip bags, and includes a tall mounting section 110 and a base section 120 connected to the mounting section 110. A through hole 130 is formed where the mounting section 110 and the base section 120 are joined. Figure 8(A) is a plan view of the drip bag support device 4, and Figure 8(B) is a cross-sectional view of the drip bag support device 4 shown in Figure 8(A) along the line B-B. 【0051】 Similar to the drip bag support device 1, the mounting part 110 has a tall, slender shape, and the through hole 130 formed at the point where the mounting part 110 and the base part 120 are joined is composed of two circular through holes 131 and 132. 【0052】 The base portion 120, like the base portion 20 of the drip bag auxiliary device 1, has a cylindrical shape with an open bottom and is composed of a flat plate portion 121 and a leg portion 122. The flat plate portion 121 is provided with projections 140 (projections 141 and 142) that extend vertically downward from the periphery of the through hole 130, with projection 141 extending from the periphery of the through hole 131 and projection 142 extending from the periphery of the through hole 132. The projections 140 are cylindrical with open top and bottom surfaces, and the height of the projections 140 (length in the vertical direction in Figure 8(B)), which is the length that extends, is equal to or smaller than the height of the leg portion 122, for example, about 8 mm. 【0053】By providing the projection 140 in this way, when extracting coffee from the drip bag 40 into a cup using the drip bag assist device 4, the possibility of the extracted coffee leaking out of the cup can be suppressed. That is, when extracting coffee using the drip bag assist device 1 without the projection, the coffee dripping from the drip bag 40 may leak out of the cup by running down the back (bottom) side of the flat plate portion 21 through the through hole 30 and further down the inside of the leg portion 22. In contrast, when using the drip bag assist device 4 with the projection 140, the coffee dripping from the drip bag 40 falls into the cup by running down the inside of the projection 140 through the through hole 130, thus suppressing leakage out of the cup. 【0054】 The height of the projection 140 may be greater than the height of the leg portion 122. However, if the projection 140, rather than the leg portion 122, comes into contact with the flat surface when the drip bag support 4 is placed on a flat surface, causing the drip bag support 4 to become unstable, then it is preferable that the height of the projection 140 be less than or equal to the height of the leg portion 122. The projection 140 may be in a shape other than cylindrical, as long as it extends from the periphery of the through hole 130. Furthermore, projections similar to the projection 140 may be provided on the drip bag support 2 and 3 in the second and third embodiments. 【0055】 A fifth embodiment of the present invention will now be described. In the drip bag support devices of the first to fourth embodiments, the mounting part has a shape in which the top and bottom of a truncated square pyramid are inverted and the vertex and hypotenuse are slightly rounded. However, as described above, the mounting part can have other shapes as long as it can accommodate multiple drip bags, and a rectangular parallelepiped shape without rounded edges is also possible. 【0056】Figures 9 and 10 show an example of a drip bag support device (fifth embodiment) having a rectangular parallelepiped-shaped mounting section. Similar to the drip bag support device 4 in the fourth embodiment, the drip bag support device 5 is shaped to accommodate two two-point hook type drip bags, and includes a tall mounting section 150 and a base section 160 connected to the mounting section 150. A through hole 170 is formed where the mounting section 150 and the base section 160 are joined, and a projection 180 is provided extending vertically downward from the periphery of the through hole 170. The mounting section 150 is rectangular in shape, and the through hole 170 is a single rectangular shape. Figure 9 is a perspective view of the drip bag support device 5, Figure 10(A) is a plan view of the drip bag support device 5, and Figure 10(B) is a cross-sectional view of the drip bag support device 5 shown in Figure 10(A) along line A-A. 【0057】 The mounting section 150 is tall and has a rectangular shape. The mounting section 150 can accommodate two two-point hook type drip bags, so the top surface is approximately the same size as the mounting section 10 in the first embodiment, for example, it is a rectangle with a length (length in the front-to-back direction in Figure 9) of about 12 cm and a width (length in the left-to-right direction in Figure 9) of about 6 cm. 【0058】Since the mounting section 150 is shaped like a rectangular parallelepiped, its bottom surface is also rectangular in shape, the same size as the top surface, but it has a shape that slopes inward toward the through hole 170. That is, the four sides of the mounting section 150 (front, rear, right, and left sides) extend vertically downward from the position of the top surface to a predetermined height (length in the vertical direction in Figure 9), as shown in Figure 10, and from that predetermined height they become inclined surfaces (hereinafter referred to as "inclined surfaces") that are in contact with the periphery of the through hole 170. The angle of the inclined surfaces relative to the horizontal plane is, for example, about 15° for the inclined surfaces on the front and rear sides (upper and lower inclined surfaces in Figure 10(A)), and about 20° for the inclined surfaces on the right and left sides (left and right inclined surfaces in Figure 10(A)). The height of the mounting section 150 is approximately the same size as the mounting section 10, for example, 6 to 7 cm. Furthermore, the through-hole 170 is formed in the center of the lower surface of the installation part 150 and has a rectangular shape, for example, approximately 5 cm vertically and approximately 2 cm horizontally. Therefore, the length of the side extending vertically downward is set according to the size of the installation part 150, the angle of the inclined surface, the size of the through-hole 170, etc. For example, if these are the values mentioned above, the extended length is 5 to 6 cm. 【0059】 The mounting section 150 has a rectangular parallelepiped shape externally and an inclined surface internally. As shown in Figure 10(B), the inclined surface becomes thicker as it moves away from the through-hole 170. The inclined surface does not need to be thicker; it can be the same thickness as the other parts. By forming such an inclined surface, the coffee dripping from the drip bag 40 installed in the mounting section 150 can be poured into the cup through the through-hole 170 without remaining inside the mounting section 150. 【0060】The base portion 160, like the base portion 120 of the drip bag assist device 4, is composed of a disc-shaped flat plate portion 161 that is joined to the installation portion 150, and leg portions 162 that extend vertically downward from the periphery of the flat plate portion 161. Furthermore, a projection portion 180 is provided that extends vertically downward from the periphery of the through hole 170. The flat plate portion 161 is larger than the rim of the cup on which the drip bag assist device 5 is installed, and its size takes into account the size of the installation portion 150 to which it is joined. For example, if the bottom surface of the installation portion 150 is a rectangle with a length of approximately 12 cm and a width of approximately 6 cm, the diameter of the top surface of the flat plate portion 161 is approximately 14 cm. The height of the leg portion 162 and the height of the projection portion 180 are approximately the same as in the case of the drip bag assist device 4, for example, approximately 1 cm and approximately 8 mm, respectively. Note that the projection portion 180 is optional. In this case, the leg portion 162 is also optional. 【0061】 Although the outer surface of the mounting portion 150 is flat, some or all of its outer surface may be a rounded surface that curves gently outward in a convex shape. In addition, a slightly raised portion (hereinafter referred to as the "raised portion") may be provided near the center or over the entire upper end of the right and left sides of the mounting portion 150 that extend in the longitudinal direction (front-to-back direction in Figure 9), as shown in Figure 11. Figure 11 is a cross-sectional view of a drip bag support device 5 similar to that of Figure 10(B). By providing such raised portions 151 at the upper ends of the right and left sides, the drip bag support device 5 can be made easier to hold by using these raised portions 151 as a handle. 【0062】 A sixth embodiment of the present invention will now be described. In the drip bag support devices of the first to fifth embodiments, the legs of the base extend vertically downward from the periphery of the flat plate. However, the legs can be provided at any position on the back surface (the lower surface in the vertical direction) of the flat plate, as long as the drip bag support device does not become unstable when it is placed on a cup or when it is placed on a flat surface. 【0063】Figure 12 shows an example of a drip bag support device (sixth embodiment) in which the leg portion 162 is provided on the back surface of the flat plate portion 161 between the periphery and the center, compared to the drip bag support device 5 in the fifth embodiment. The drip bag support device 6 is shaped to accommodate two two-point hook type drip bags, similar to the drip bag support device 5, and includes an installation portion (not shown) and a base portion 190 connected to the installation portion. A through hole 170 is formed at the point where the installation portion and the base portion 190 are joined, and a projection 180 is provided extending vertically downward from the periphery of the through hole 170. Figure 12 is a bottom view of the drip bag support device 6. 【0064】 The base portion 190, like the base portion 160 of the drip bag auxiliary device 5, comprises a flat plate portion 191 and a leg portion 192, but the leg portion 192 extends vertically downward from a position between the periphery and the center of the flat plate portion 191, rather than from the periphery of the flat plate portion 191. The leg portion 192 is formed in an annular shape so as to be concentric with the disc-shaped flat plate portion 191 when viewed from above, and is provided to surround the projection portion 180. For example, if the diameter of the flat plate portion 191 is about 14 cm and the through hole 170 is a rectangle with a length of about 5 cm and a width of about 2 cm, the diameter of the leg portion 192 is about 8 cm. The height of the leg portion 192 is approximately the same as the height of the leg portion 162 of the base portion 160, for example, about 1 cm. The thickness of the leg portion 192 is approximately the same as that of the leg portion 162 of the base portion 160, and is 1 to 2 mm if the drip bag support device 6 is made of AS resin. The leg portion 192 does not have to be annular; it may be rectangular or other shapes, or composed of multiple spaced-apart parts, as long as the stability of the drip bag support device 6 can be ensured. 【0065】 A seventh embodiment of the present invention will now be described. In the first to sixth embodiments, the drip bag aid has a structure comprising an installation part and a base part, but in the present invention, a structure without a base part is also possible. That is, the installation part is placed on the rim of the cup. 【0066】An example of a drip bag support device without a base (seventh embodiment) is shown in Figures 13 and 14. The drip bag support device 7 is shaped to accommodate two two-point hook type drip bags and is equipped with a tall mounting section 200. Figure 13 is a perspective view of the drip bag support device 7, Figure 14(A) is a plan view of the drip bag support device 7, and Figure 14(B) is a cross-sectional view of the drip bag support device 7 shown in Figure 14(A) along the line A-A. 【0067】 The mounting section 200 is tall and roughly rectangular in shape, but its front and rear surfaces are gently curved outwards in a convex shape, and its top surface is an open surface. The drip bag 40 is inserted into the mounting section 200 from the top surface, which is the open surface. The drip bags 41 and 42 are mounted side by side by attaching the hooks attached to both sides of the drip bag 40 to the long edge of the top surface of the mounting section 200. Therefore, the length of the long edge is long enough to attach the two hooks 411 and 421 that each of the drip bags 41 and 42 has, for example, about 12 cm, but because the front and rear surfaces are curved, the longest part of the curved section is about 13 cm. The short side of the top surface (the side extending in the left-right direction in Figure 13) is long enough so that when the hooks of the opened drip bag 40 are attached to the long edge, the opening of the filter becomes roughly rectangular in shape, for example, about 6 cm. Furthermore, the front and / or rear surfaces do not have to be curved; they may be flat. 【0068】 As shown in Figure 14(A), a rectangular through-hole 220 is drilled in the lower part of the installation section 200. The through-hole 220 is formed in the center of the lower surface of the installation section 200, and its dimensions are, for example, approximately 5 cm in length (length in the front-to-back direction in Figure 13) and approximately 2 cm in width (length in the left-to-right direction in Figure 13). 【0069】The mounting section 200 is roughly rectangular in shape, so the bottom surface is the same size as the top surface, but it has a shape that slopes inward toward the through hole 220. That is, the four sides of the mounting section 200 (front, rear, right, and left sides) extend vertically downward from the position of the top surface to a predetermined height (length in the vertical direction in Figure 13), as shown in Figure 14, and from that predetermined height they become inclined surfaces that are in contact with the periphery of the through hole 220. The angle of the inclined surfaces with respect to the horizontal plane is, for example, about 15° for the inclined surfaces on the front and rear surfaces (upper and lower inclined surfaces in Figure 14(A)), and about 20° for the inclined surfaces on the right and left sides (left and right inclined surfaces in Figure 14(A)). The height of the mounting section 200 is such that when the drip bag 40 is installed on the mounting section 200, the lower end of the drip bag 40 does not come into contact with the bottom surface of the mounting section 200, or if it does, only a part of it comes into contact, for example, about 6 to 7 cm. Therefore, the length of the side surface of the installation section 200 that extends vertically downward is set according to the size of the installation section 200, the angle of the inclined surface, the size of the through hole 220, etc. For example, if these are the values mentioned above, the length of the extension is 5 to 6 cm. 【0070】 The mounting section 200 has a roughly rectangular parallelepiped shape externally, with an inclined surface inside. As shown in Figure 14(B), the inclined surface becomes thicker as it moves away from the through-hole 220. However, the inclined surface does not need to be thicker; it may be the same thickness as the other parts. Furthermore, the shape of the mounting section 200 is not limited to a roughly rectangular parallelepiped; for example, it may have a shape like an inverted pyramidal pyramid, where the bottom surface is slightly smaller than the top surface. 【0071】Legs 210 are connected to the lower part of the mounting section 200. Two legs 210 are formed so as to extend vertically downward from the edge located in the longitudinal direction (front-to-back direction in Figure 13) of the lower part of the mounting section 200. Since the mounting section 200 is placed on the rim of the cup, the legs 210 prevent the drip bag support 7 from sliding and falling out of the cup. The legs 210 also have functions such as acting as legs when the drip bag support 7 is placed on a flat surface. Therefore, the height of the legs 210 is sized to take these functions into consideration, for example, it is about 1 cm. 【0072】 The drip bag support device 7 is provided with a projection 230 that extends vertically downward from the periphery of the through hole 220 so as to be connected to the installation portion 200. The projection 230 has the shape of a rectangular parallelepiped with its top and bottom surfaces open, and the height of the projection 230 (length in the vertical direction in Figure 14(B)), which is the length that extends, is equal to or less than the height of the leg portion 210, for example, about 8 mm. 【0073】 The height of the projection 230 may be greater than the height of the leg portion 210, but in cases where the projection 230, rather than the leg portion 210, contacts the flat surface when the drip bag support device 7 is placed on a flat surface, causing the drip bag support device 7 to become unstable, the height of the projection 230 is preferably less than or equal to the height of the leg portion 210. The projection 230 may be a shape other than a rectangular parallelepiped, as long as it extends from the periphery of the through hole 220. Also, the leg portion 210 may be a shape that extends only from both ends of the edge, for example, rather than extending from the entire edge of one edge, as long as the stability of the drip bag support device 7 can be ensured. As with the leg portion 192 of the base portion 190 in the sixth embodiment, the leg portion 210 may be a shape that extends vertically downward from a position between the lower periphery and the center of the installation portion 200. In this case, the leg portion 210 may be formed in an annular shape that surrounds the projection portion 230, similar to the leg portion 192. The projection portion 230 is optional, and in this case, the leg portion 210 is also optional. Furthermore, as with the mounting portion 150 in the fifth embodiment, raised portions may be provided at the upper ends of the right and left sides of the mounting portion 200. 【0074】The drip bag support 7 is made of a material that has sufficient strength to maintain stability even when hot water is poured into the installed drip bag, heat resistance to withstand boiling water, and a weight that does not burden the cup on which the drip bag support 7 is placed. For example, the drip bag support 7 is made from stainless steel, AS (acrylonitrile styrene) resin, PP (polypropylene) resin, polycarbonate, heat-resistant glass, copper, porcelain, ceramics, paper (preferably water-resistant or heat-resistant), etc. The thickness of the drip bag support 7 is determined according to the material, taking into consideration the strength, heat resistance, weight, etc. For example, if it is made of AS resin, the thickness of the drip bag support 7 is 1 to 2 mm. 【0075】 The drip bag support device 7 can accommodate not only two-point hook type drip bags, but also other types of drip bags such as three-point hook type drip bags and top-loading type drip bags. For example, Figure 15 shows an example of a top-loading type drip bag being installed on the drip bag support device 7. Figure 15 shows the drip bag support device 7 with two top-loading type drip bags 240 (drip bags 241 and 242) installed on a cup 250. 【0076】 As shown in Figure 15, the drip bags 241 and 242 are installed side by side along the longitudinal direction of the installation section 200 by placing a pair of wings (support pieces 241a and 242a) attached to both sides of each drip bag so that they span across the long edges of the installation section 200. The drip bag support device 7 is then installed so that the through hole 220 is located near the center of the rim of the cup 250. 【0077】 The present invention is not limited to the above embodiments, and various modifications are possible without departing from the spirit of the invention. Furthermore, matters not explicitly disclosed in the above embodiments, such as the size of the mounting part and the base part, do not deviate from what is normally practiced by those skilled in the art, and values that can be easily anticipated by those skilled in the art can be adopted. 【0078】1, 2, 3, 4, 5, 6, 7 Drip bag support 10, 50, 80, 110, 150, 200 Mounting part 20, 60, 90, 120, 160, 190 Base part 21, 121, 161, 191 Flat plate part 22, 122, 162, 192, 210 Leg part 30, 31, 32, 70, 71, 72, 130, 131, 132, 170, 220 Through hole 40, 41, 42, 43, 44, 240, 241, 242 Drip bag 140, 141, 142, 180, 230 Projection part 151 Raised part 241a, 242a Support piece 250 Cup 411, 421 Hook
