Description

【Technical Field】 【0001】 The present invention relates to a drip bag assist device for assisting the operation of extracting coffee from a drip bag into a container, and a coffee extraction method using the same. 【Background Art】 【0002】 A drip bag (sometimes referred to as a "drip pack") in which one cup of coffee powder is individually packaged in a liquid-permeable paper (filter) and fixed to a cup to brew coffee can brew authentic coffee simply without using instruments such as a dripper, and thus 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. The hook-type drip bag is installed on the cup by hanging a hook attached to the outside of the filter 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 "two-point hook type"), such as an X-type or an arch-type, and a type that fixes it at three points (hereinafter referred to as "three-point hook type"), such as a VFR-type. The conical drip bag is installed on the cup by placing the drip bag on top of the cup. 【0004】 As described above, the drip bag can brew coffee without using other instruments. 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 and preventing the coffee drip filter from being 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. [Prior art documents] [Patent Documents] 【0008】 [Patent Document 1] Utility Model Registration No. 3197073 Gazette [Patent Document 2] Japanese Patent Publication No. 2007-159897 [Patent Document 3] Japanese Patent Publication No. 2024-61117 [Overview of the project] [Problems that the invention aims to solve] 【0009】 However, the devices proposed in Patent Documents 1-3 can only accommodate one drip bag. Since 8-12 grams of coffee grounds are commonly used in a single drip bag, and the appropriate amount of coffee extracted from this quantity is considered to be 100-140cc, extracting a larger quantity of coffee or a stronger coffee requires switching between multiple drip bags, which is a time-consuming process. When making iced coffee using a drip bag, the process typically involves either 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 purposes such as 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. [Means for solving the problem] 【0011】 As a result of diligent research to solve the above problems, the inventors of this invention have found that the following invention is suitable for the above purpose, leading to the present invention.

The first drip bag auxiliary tool according to the present invention includes an installation part for installing a drip bag, and a pedestal part that is connected to the installation part and is placed on the edge (opening edge part) of a container such as a cup into which coffee extracted from the drip bag is poured. A plurality of drip bags can be arranged and installed in the installation part. For example, in the case of a two-point hook type drip bag, the installation part has an opening surface 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. Open the filter filled with coffee powder, open the hook, and insert a plurality (for example, two) of drip bags in a state where hot water can be poured by hanging them on the side surface of the installation part from the opening surface and store them inside. Note that the drip bag auxiliary tool according to the present invention can also be used for three-point hook type drip bags, conical drip bags, etc., and it is also possible to use drip bags of different types mixed. 【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, or the same number as the number of drip bags that can be installed, can be formed, or any number of through holes. 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 auxiliary 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 point where the installation part 10 and the base part 20 are joined. 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 AA. Figure 3 is a perspective view of the drip bag support device 1 with drip bags 40 (drip bags 41 and 42) installed. In Figures 1 and 3, as indicated by the arrows, the top, bottom, 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 top surface of the installation section 10 has the shape of a rectangle 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 long side (the side extending in the front-to-back direction in Figure 3) of the top surface (hereinafter referred to as the "long edge"). Therefore, the long side of the top 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 top surface (the side extending in the left-to-right direction in Figure 3) is long enough so that the opening of the filter of the opened drip bag 40 is roughly rectangular in shape 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 connect 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 consists 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 approximately 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 sizes of base portions 20 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 auxiliary device 1, when two drip bags 41 and 42 are placed on the mounting section 10, through-holes 31 and 32 are formed at positions opposite the lower end 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 support device 1, the entire lower surface of the mounting section 10 is joined to the upper surface of the flat plate section 21. Therefore, the through hole 30 is 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 hole 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 circular; they can be square 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 being 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 can be made from stainless steel, AS (acrylonitrile styrene) resin, PP (polypropylene) resin, polycarbonate, heat-resistant glass, copper, porcelain, or ceramic. The thickness of the drip bag support 1 is determined by the material, taking into account 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 will also be 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 how to brew coffee using a drip bag aid 1 with this structure. 【0032】 First, the drip bag support 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 1, and then the drip bag support 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 support device 1. Since the drip bags 41 and 42 are placed side by side, a roughly equal amount of hot water can be poured onto 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 aid 1 has finished, remove the drip bag aid 1 from the cup. In this case, you may also remove the drip bags 41 and 42 from the drip bag aid 1 first, and then remove the drip bag aid 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 cover the entire rim of the cup. The legs 22 do not have to extend vertically downward from the entire periphery of the flat plate section 21, but rather extend 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. 【0037】 A second embodiment of the present invention will now be described. In the first embodiment, the mounting section 10 is tall, but the present invention also allows the use of a short mounting section, that is, a mounting section in which the lower end of the drip bag does not fit when the drip bag is installed. 【0038】 An example of a drip bag support device equipped with a short, tall mounting section (second embodiment) is shown in Figures 4 to 6. The drip bag support device 2, like the drip bag support device 1, 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 shorter in height. Two through holes 71 and 72 are formed at the point where the mounting section 50 and the base section 60 are joined. Figure 4 is a perspective view of the drip bag support device 2, Figure 5 is a plan view of the drip bag support device 2, and Figure 6 is a front view of the drip bag support device 2 with a drip bag 40 installed. 【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 joint between the mounting section 50 and the base section 60 are square in shape. When the drip bag 40 is placed on the mounting section 50, the lower end of the drip bag 40 passes through the through holes 70 and reaches below the drip bag support 2, so the through holes 70 are sized to allow the lower part of the drip bag 40 to pass through. For example, the through holes 70 are square with sides of approximately 4 cm. Furthermore, as long as the bottom of the drip bag 40 can pass through, the number of through-holes 70 can be as small as one, and the shape does not have to be square; other shapes are also acceptable. 【0042】 In this way, the lower part of the drip bag 40 installed in the installation section 50 protrudes below the drip bag auxiliary device 2, making it possible to immerse the lower part of the filter in the extracted coffee during the process of brewing coffee into a cup. Since immersion of the lower part of the filter in the coffee allows for the extraction of a richer coffee, the use of the drip bag auxiliary device 2 is suitable for making iced coffee and other beverages where a rich coffee is preferred. As with the drip bag support device 1, the shape of the mounting part 50 and / or base part 60 is not limited to the shape described above, and other shapes are also acceptable. 【0043】 A third embodiment of the present invention will now be described. While the drip bag support devices 1 and 2 in the first and second embodiments are capable of holding two drip bags, the drip bag support device according to the present invention can also be shaped to hold three or more drip bags. 【0044】 Figure 7 shows an example of a drip bag support device (third embodiment) that can accommodate four drip bags. The drip bag support device 3 is shaped to accommodate four two-point hook type drip bags, and includes a short-height mounting section 80 similar to the drip bag support device 2 of the second embodiment, and a base section 90 connected to the mounting section 80. A through hole (not shown) is formed where the mounting section 80 and the base section 90 are joined. Figure 7 is a perspective view of the drip bag support device 3 with four drip bags 41, 42, 43, and 44 installed. 【0045】 The mounting section 80 is short in height, similar to the mounting section 50 of the drip bag auxiliary device 2, but its length in the longitudinal direction (front-to-back direction in Figure 7) is longer than that of the mounting section 50 in order to accommodate four drip bags 41-44. For example, the height of the side of the mounting section 80 (length in the vertical direction in Figure 7) is approximately 2 cm, and the lengths of the long sides of the top and bottom surfaces (sides extending in the front-to-back direction in Figure 7) are approximately 24 cm and 23 cm, respectively. The lengths of the short sides of the top and bottom surfaces (sides extending in the left-to-right direction in Figure 7) are roughly the same as those of the mounting section 50, for example, approximately 6 cm and 5 cm, respectively. 【0046】 The base portion 90, like the base portion 60 of the drip bag auxiliary device 2, has a cylindrical shape with an open bottom, but it is larger than the base portion 60. For example, the diameter of the top surface of the flat portion of the base portion 90 is approximately 25 cm. 【0047】 The through-holes formed at the joint between the mounting section 80 and the base section 90 are four in number, corresponding to the number of drip bags that can be installed in the mounting section 80. Similar to the through-holes 70 of the drip bag support device 2, for example, they are square in shape and are sized to allow the bottom of the drip bag to pass through (for example, with sides approximately 4 cm long). 【0048】 This type of drip bag aid 3 is somewhat large for use with a regular cup, and the bottom of the drip bag protrudes below the drip bag aid 3. Therefore, it is suitable for use, for example, when preparing iced coffee in a container with a large opening. As with the drip bag auxiliary device 2, the shape of the mounting part 80 and / or base part 90 is not limited to the shape described above and may be other shapes, and the number and / or shape of the through holes are not limited to the shape described above. 【0049】 A fourth embodiment of the present invention will now be described. In the present invention, it is possible to provide a projection extending vertically downward from the periphery of the through hole 30 to the drip bag auxiliary device 1 in the first embodiment. 【0050】 Figure 8 shows an example of a drip bag aid equipped with a protrusion (fourth embodiment). The drip bag support device 4, like the drip bag support device 1, 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 line BB. 【0051】 Similar to the drip bag support device 1, the mounting section 110 has a tall, slender shape, and the through-hole 130 formed at the point where the mounting section 110 and the base section 120 are joined consists 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, the drip bag support 2 and 3 in the second and third embodiments may also be provided with projections similar to the projection 140. 【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 that is like an inverted truncated square pyramid with the vertex and hypotenuse slightly rounded. However, as mentioned above, the mounting part can have other shapes as long as it can accommodate multiple drip bags, and a rectangular prism shape without rounded edges is also possible. 【0056】 Figures 9 and 10 show an example of a drip bag support device (fifth embodiment) that has a rectangular parallelepiped-shaped mounting section. The drip bag support device 5, like the drip bag support device 4 in the fourth embodiment, 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 shaped like a rectangular parallelepiped, and the through hole 170 is a single rectangular hole. 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 AA. 【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 approximately 12 cm and a width (length in the left-to-right direction in Figure 9) of approximately 6 cm. 【0058】 Since the mounting section 150 is rectangular in shape, 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 side, and left side) 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 surfaces (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 as that of 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 exterior and an inclined interior. As shown in Figure 10(B), the inclined portion becomes thicker as it moves away from the through-hole 170. However, the inclined portion does not need to be thicker; it may 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 installation section 150 can be poured into the cup through the through hole 170 without remaining inside the installation section 150. 【0060】 The base portion 160, like the base portion 120 of the drip bag assist device 4, consists of a disc-shaped flat plate portion 161 that connects 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 connects. 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 the drip bag assist device 5, similar to Figure 10(B). By providing such raised portions 151 at the upper ends of the right and left sides, the drip bag assist 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 by itself. 【0063】 Figure 12 shows an example of a drip bag assist device (sixth embodiment) in which the leg portion 162 is provided at a position between the periphery and the center on the back surface of the flat plate portion 161, compared to the drip bag assist device 5 of the fifth embodiment. The drip bag support device 6, like the drip bag support device 5, is shaped to accommodate two two-point hook type drip bags, and comprises a mounting section (not shown) and a base section 190 connected to the mounting section. A through hole 170 is formed where the mounting section and the base section 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 approximately 14 cm and the through hole 170 is a rectangle with a length of approximately 5 cm and a width of approximately 2 cm, the diameter of the leg portion 192 is approximately 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, approximately 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 for example, if the drip bag support 6 is made of AS resin, it is 1 to 2 mm thick. Furthermore, 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 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 assist device 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. In other words, the installation part is placed on the rim of the cup. 【0066】 Figures 13 and 14 show an example of a drip bag assist device (seventh embodiment) that does not include a base portion 160, as opposed to the drip bag assist device 5 in the fifth embodiment. The drip bag support device 7, like the drip bag support device 5 in the fifth embodiment, is shaped to accommodate two two-point hook type drip bags and has a tall mounting section 200, but does not have a base, and legs 210 are connected to the lower part of the 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 line AA. 【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. The mounting section 200 can accommodate two two-point hook type drip bags, so the top surface is roughly the same size as the mounting section 150 of the drip bag support device 5, but because the front and rear surfaces are curved, the length of the long edge where the hooks of the drip bag 40 are attached is, for example, about 12 cm, but the longest part of the curved section is about 13 cm. Note that the front and / or rear surfaces do not have to be curved and may be flat. 【0068】 The lower part of the mounting section 200 has a through hole 220, which is rectangular in shape, similar to the through hole 5 of the drip bag auxiliary device. 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). Inside the mounting section 200, similar to the mounting section 150, there is an inclined surface that slopes toward the through hole 220, and this inclined surface is thicker. In addition, a projection 230 is provided that extends vertically downward from the periphery of the through hole 220, connecting to the mounting section 200. 【0069】 The legs 210 are formed in pairs, extending 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. The legs 210 have the same functions as the legs of the base in other embodiments, namely, they prevent the drip bag support 7 from sliding and falling out of the cup, and they act as legs when the drip bag support 7 is placed on a flat surface. Therefore, the height of the legs 210 is the same as the height of the legs of the base, for example, about 1 cm. The thickness of the legs 210 is also similar, for example, 1 to 2 mm if the drip bag support 7 is made of AS resin. 【0070】 Furthermore, the leg portion 210 does not have to extend from the entire edge of one side, but may extend only from both ends of the edge, for example, as long as the stability of the drip bag support device 7 can be ensured. Also, like the leg portion 192 of the base portion 190 in the sixth embodiment, the leg portion 210 may extend 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. In addition, as with the installation portion 150 in the fifth embodiment, raised portions may be provided at the upper ends of the right and left sides of the installation portion 200. 【0071】 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.
