DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] Hereinafter, an embodiment of the dripper of the present invention will be described with reference to the drawings. The dripper of the present invention is a dripper with a simple design that omits side walls and is easy to clean. The dripper can filter powdered coffee using a coffee filter as a filtering object, but can also be suitably used to filter tea or soup stock using the same filter. [First embodiment]

[0016] A dripper 11 of a first embodiment will be described with reference to Figs. 1 to 7. As shown in Figs. 1 to 4, dripper 11 includes a first ring portion 12 located on the upper side, a second ring portion 13 located below first ring portion 12, a plurality of connecting rods 14 connecting first ring portion 12 and second ring portion 13, a gripping portion 15 provided so as to protrude from second ring portion 13, and spaces 16 provided between connecting rods 14. That is, dripper 11 of this embodiment and drippers 11 of the second and third embodiments described below do not have a funnel-shaped sidewall, and are capable of supporting a coffee filter 17 only by connecting rods 14.

[0017] The first ring portion 12, the second ring portion 13, the multiple connecting rods 14, and the grip portion 15 are integrally formed by wires made of metal, such as steel, stainless steel, aluminum alloy, brass, copper, and the like. It is desirable that the first ring portion 12, the second ring portion 13, the multiple connecting rods 14, and the grip portion 15 are made of stainless steel, for example, in terms of low cost, high rigidity, and low thermal conductivity. Each of the multiple connecting rods 14 is welded to the first ring portion 12 at one end and welded to the second ring portion 13 at the other end. The connecting rods 14 are bent in a "L" shape. The multiple connecting rods 14 are arranged discretely with equal intervals. That is, the connecting rods 14 are arranged at positions shifted by 72 degrees around the central axis S.

[0018] The first ring portion 12 is formed in a circular shape. The second ring portion 13 is formed in a circular shape, for example, and has a diameter equal to or larger than that of the first ring portion 12. The second ring portion 13 may have a diameter smaller than that of the first ring portion 12. The shape of the second ring portion 13 may be a polygonal shape or a discontinuous circular shape. As shown in FIG. 2, the central axis S passing through the center C1 of the first ring portion 12 passes through the center C2 of the second ring portion 13, but may be deviated from the center C2 of the second ring portion 13.

[0019] 1 to 4, the multiple connecting rods 14 are preferably configured by 4 to 10 pieces, preferably 4 to 8 pieces, and more preferably 4 to 6 pieces, but are configured by 5 pieces in this embodiment. Each of the multiple connecting rods 14 has a first rod portion 21 extending from the first ring portion 12 toward the approximate center CA of the second ring portion 13, a folded portion 22 provided at the approximate center CA of the second ring portion 13, and a second rod portion 23 extending from the folded portion 22 toward the second ring portion 13. Here, the approximate center CA of the second ring portion 13 is a concept including not only the center of the second ring portion 13 but also its surrounding area.

[0020] Here, as shown in FIG. 2, a virtual cone 24 (virtual cone shape) is considered with the first ring portion 12 as the bottom surface and the center C2 of the second ring portion 13 as the apex. The central axis of this virtual cone 24 coincides with the central axis S passing through the center C1 of the first ring portion 12 and the center C1 of the second ring portion 13. The first rod portion 21 is curved so as to be convex toward the outside O in the normal direction of the generatrix 24A of the virtual cone 24. Therefore, in the dripper 11 of this embodiment, the bowl portion 25 formed by the multiple first ring portions 12 and capable of supporting the coffee filter 17 has a shape like a downwardly convex parabola. Therefore, compared to a dripper 11 formed in a simple cone shape, the volume of hot water that can be stored inside the coffee filter 17 attached thereto is increased.

[0021] As shown in FIG. 3, the first rod portion 21 extends radially when viewed from above. That is, the first rod portion 21 may extend, for example, linearly or spirally when viewed from above. It is more preferable that the first rod portion 21 extends linearly when viewed from above, since the shape is simplified. Each of the multiple folded portions 22 is disposed at the vertices of a polygon having four or more sides. In this embodiment, the multiple folded portions 22 are disposed at the vertices of a pentagon. Each of the multiple folded portions 22 is formed by bending so that the outside becomes a small-diameter arc.

[0022] Moreover, each of the portions 21A near the folded-back portions 22 of the multiple first rod portions 21 forms a side of a polygon. As shown in Fig. 3, in this embodiment, the portions 21A near the folded-back portions 22 of the first rod portions 21 form a side of a pentagon. The bottom end of the coffee filter 17 can be reliably supported by the sides of this polygon (pentagon), effectively preventing the coffee filter 17 from falling out downward.

[0023] As shown in Fig. 1, Fig. 4, etc., the second rod portion 23 is provided linearly. The second rod portion 23 extends radially from the inner folded portion 22 toward the outer second ring portion 13. The second rod portion 23 is provided at a position overlapping with the first rod portion 21 when viewed from above, but does not have to overlap when viewed from above. As shown in Fig. 2, the second rod portion 23 is provided above the second ring portion 13.

[0024] The gripping portion 15 is provided from a part of the second ring portion 13 so as to protrude obliquely upward and radially outward of the second ring portion 13. The gripping portion 15 is arranged so as to form a predetermined angle θ with respect to the horizontal plane when the second ring portion 13 is installed on a horizontal plane. The installation angle θ of the gripping portion 15 is, for example, 30 to 60 degrees. By providing the gripping portion 15 so as to protrude outward in this manner, the user can hold the dripper 11 after use without touching the coffee filter 17. In addition, after pouring coffee powder into the coffee filter 17, the user can flatten the coffee powder by holding the gripping portion 15 and shaking the dripper 11 before pouring hot water. Furthermore, after pouring hot water, the user can also stir the coffee powder and hot water in the coffee filter 17 by holding the gripping portion 15 and shaking the dripper 11 to promote even steaming.

[0025] Next, the operation of dripper 11 of the present embodiment will be described with reference to FIGS.

[0026] Dripper 11 of the present embodiment is placed on the top of a cup. A commercially available conical coffee filter 17 is set in dripper 11 of the present embodiment. At this time, tip 17A of conical coffee filter 17 is placed in a position surrounded by multiple folded-back portions 22 (approximately center portion CA of second ring portion 13).

[0027] Ground coffee is placed on the top side of coffee filter 17, and hot water is poured toward the coffee and coffee filter 17. When the hot water is poured, cone-shaped coffee filter 17 deforms to follow the "downwardly convex parabolic shape" of bowl portion 25 of dripper 11.

[0028] At this time, because bowl portion 25 capable of supporting coffee filter 17 has a shape like a downward convex parabola, the volume of hot water that can be stored inside coffee filter 17 is increased compared to a simple cone-shaped dripper. Also, by making bowl portion 25 have a shape like a downward convex parabola, the area of ​​the portion of the bottom of bowl portion 25 that is approximately horizontal is increased compared to a simple cone-shaped dripper. Therefore, when hot water is poured into dripper 11, the hot water can be received by the bottom of bowl portion 25 of dripper 11 as much as possible, preventing lightweight dripper 11 from tipping over and coffee filter 17 from falling off dripper 11, and stabilizing dripper 11 and coffee filter 17.

[0029] Furthermore, bowl portion 25 of dripper 11 of this embodiment forms an arc that takes into consideration the shape of coffee filter 17 after it absorbs hot water and deforms into a downwardly convex parabolic shape. In other words, bowl portion 25 of dripper 11 of this embodiment forms a natural shape that takes into consideration the gravity acting on coffee filter 17 when hot water is poured in. This makes it difficult for first rod portion 21 to bite into the inside of coffee filter 17 into which hot water has been poured. This stabilizes the shape of coffee filter 17 when hot water is poured in, and prevents problems such as coffee grounds and hot water overflowing from coffee filter 17 as much as possible.

[0030] In addition, the dripper 11 of this embodiment has excellent ventilation because spaces 16 are formed between the first rod portions 21. Normally, when hot water is poured onto coffee powder, gas is generated from the coffee powder, and if an air passage is not secured, the coffee may not be extracted properly. In this embodiment, an air passage is secured via the spaces 16, so that it is possible to prevent as much as possible the occurrence of problems that would cause the coffee to be extracted poorly due to gas generated during coffee extraction.

[0031] As shown in Fig. 7, some of the hot water is filtered through the coffee filter 17 and leaks out to the bottom side of the coffee filter 17, but flows along the bottom side of the coffee filter 17 (filter paper) due to surface tension. As a result, the filtered coffee does not drip randomly and scatter around, but gathers at a position surrounded by multiple folded parts 22 (approximately the center CA of the second ring part 13) and falls quietly from there into the cup. This prevents the coffee from splashing out of the cup.

[0032] According to this embodiment, the following can be said. The dripper 11 includes a circular first ring portion 12, a circular second ring portion 13 provided below the first ring portion 12, and a plurality of connecting rods 14 connecting the first ring portion 12 and the second ring portion 13, the plurality of connecting rods 14 having a first rod portion 21 extending from the first ring portion 12 toward a substantially central portion CA of the second ring portion 13 and convex toward an outer side O in a normal direction of a generatrix 24A of a virtual cone 24 having the first ring portion 12 as a bottom surface and the center of the second ring portion 13 as an apex, a folded portion 22 provided at the substantially central portion CA, and a second rod portion 23 extending from the folded portion 22 toward the second ring portion 13 and extending in a direction overlapping with the first rod portion 21 when viewed from above.

[0033] According to this configuration, the dripper 11 can be realized with an extremely simple structure of two ring parts 12, 13 and a plurality of connecting rods 14 connecting them. This allows the dripper 11 to be realized with a neat appearance by omitting the side wall. Furthermore, by omitting the side wall, coffee dirt and the like is less likely to accumulate on the side wall, improving cleanability. Furthermore, since dirt is less likely to accumulate, the dripper 11 can be used not only for coffee but also for filtering tea or soup stock. Furthermore, since the two ring parts 12, 13 are connected by a plurality of connecting rods 14, the stability of the shape can be improved. Furthermore, since the first rod part 21 is convex toward the outer side O in the normal direction of the generating line 24A of the virtual cone 24, the inner volume of the coffee filter 17 can be secured to be large, and a large amount of coffee can be filtered at one time. In addition, because the shape of bowl portion 25 of dripper 11 can be "shaped like a downwardly convex parabola," the area of ​​the portion of the bottom of bowl portion 25 that is approximately horizontal is increased compared to a simple conical dripper. Therefore, when hot water is poured into dripper 11, the hot water can be received at the bottom of bowl portion 25 of dripper 11 as much as possible, preventing lightweight dripper 11 from tipping over and coffee filter 17 from falling off dripper 11, and stabilizing the postures of dripper 11 and coffee filter 17. In addition, because second rod portion 23 overlaps first rod portion 21 when viewed from above, an even neater appearance can be achieved.

[0034] The bowl portion 25 of the dripper 11 of this embodiment has a natural shape that takes into consideration the load of hot water on the coffee filter 17 when hot water is poured in. This makes it difficult for the first rod portion 21 to bite into the inside of the coffee filter 17 when hot water is poured in, and the shape of the coffee filter 17 is stable, making it possible to minimize problems such as coffee grounds and hot water overflowing from the coffee filter 17.

[0035] In this case, each of the multiple folded-back portions 22 is disposed at a vertex of a polygon having four or more sides, and each of the portions 21A of the multiple first rod portions 21 near the folded-back portions 22 forms a side of the polygon.

[0036] According to this configuration, the polygonal portion of the first rod portion 21 near the folded-back portion 22 can be arranged to surround the center C2 of the second ring portion 13. According to this configuration, the polygonal portion of the first rod portion 21 can uniformly support the coffee filter 17 not only by the "points" of the folded-back portion 22 but also by the "lines" of the portion 21A near the folded-back portion 22 of the first rod portion 21. Furthermore, by making the shape of the coffee filter 17 a polygon with four or more sides, the shape of the coffee filter 17 can be stabilized when hot water is poured into the coffee filter 17, and the coffee filter 17 can be prevented from falling over as much as possible.

[0037] In this case, each of the multiple second rod portions 23 is provided above the second ring portion 13 . This configuration can prevent the bottom end of the coffee filter 17 (paper filter) from coming into contact with the liquid surface of the coffee cup as much as possible. Also, the above configuration can be structured so that the second ring portion 13 can be caught on the edge of the coffee cup. This can prevent the dripper 11 from slipping off the coffee cup.

[0038] Each of the multiple first rod portions 21 extends linearly when viewed from above. According to this configuration, the structure of the connecting rod 14 can be extremely simplified, and the shape of the connecting rod 14 allows the coffee filter 17 to be stably supported.

[0039] The second ring portion 13 has a grip portion 15 that is provided so as to protrude from the second ring portion 13 and is gripped by the user. This configuration allows the grip portion 15 to be located at a position farthest from the point where hot water is poured in to brew coffee, allowing a user holding the grip portion 15 to carry the dripper 11 without getting burned.

[0040] Spaces 16 are provided between the multiple connecting rods 14 . This configuration allows for the omission of side walls and the realization of a neat and tidy appearance of dripper 11. Furthermore, the absence of side walls allows for the realization of a lightweight dripper 11. Furthermore, because space 16 forms an air passage, it is possible to prevent as much as possible the inconvenience of coffee extraction being hindered by gases generated during coffee extraction.

[0041] The first ring portion 12, the second ring portion 13, and the connecting rod 14 are formed from metal wire, and the connecting rod 14 is welded to the first ring portion 12 at one end and to the second ring portion 13 at the other end. According to this configuration, the number of welded parts and bent parts of the wire can be minimized, and dripper 11 with a simple shape can be realized.

[0042] The wire is made of a metal. According to this configuration, by forming the wire material, particularly from steel or stainless steel, it is possible to increase the rigidity compared to aluminum alloys, etc. Also, according to the above configuration, by forming the wire material, particularly from steel or stainless steel, it is possible to reduce the thermal conductivity compared to aluminum alloys, etc., and it is possible to prevent the gripping part from becoming too hot after use. Furthermore, since the wire material is made of metal, the smell of coffee, etc. is less likely to permeate the dripper, and the dripper can also be used to filter tea or broth.

[0043] In the following embodiment, differences from the first embodiment will be mainly described, and illustrations or descriptions of parts common to the first embodiment will be omitted. [Second embodiment]

[0044] Dripper 11 of the second embodiment will be described with reference to Figures 8 to 11. Dripper 11 of the second embodiment differs from the first embodiment in the number of connecting rods 14 and the installation angle of connecting rods 14, but other configurations are the same as those of the first embodiment.

[0045] In this embodiment, the connecting rods 14 are configured by four pieces. That is, the connecting rods 14 are provided around the central axis S, shifted in position by 90 degrees each.

[0046] Each of the multiple connecting rods 14 has a first rod portion 21 extending from the first ring portion 12 toward approximately the central portion CA of the second ring portion 13, a folded portion 22 provided at approximately the central portion CA of the second ring portion 13, and a second rod portion 23 extending from the folded portion 22 toward the second ring portion 13.

[0047] Here, as shown in FIG. 9, a virtual cone 24 (virtual cone shape) is considered with the first ring portion 12 as the bottom surface and the center of the second ring portion 13 as the apex. The central axis of this virtual cone 24 coincides with the central axis S passing through the center C1 of the first ring portion 12 and the center C2 of the second ring portion 13. The first rod portion 21 is curved so as to be convex toward the outside O in the normal direction of the generatrix 24A of the virtual cone 24. Therefore, in the dripper 11 of this embodiment, the bowl portion 25 formed by the multiple first ring portions 12 and capable of supporting the coffee filter 17 has a shape like a downwardly convex parabola. Therefore, compared to a dripper formed in a simple cone shape, the volume of hot water that can be stored inside the coffee filter 17 attached thereto is increased. Also, by forming the shape of the bowl portion 25 in a downwardly convex parabola shape, the area of ​​the portion of the bottom of the bowl portion 25 that is approximately horizontal is increased compared to that of the dripper 11 that is simply a cone. Therefore, when hot water is poured into the dripper 11, the hot water can be received at the bottom of the bowl portion 25 of the dripper 11 as much as possible, preventing the lightweight dripper 11 from falling over and the coffee filter 17 from falling off the dripper 11, and stabilizing the postures of the dripper 11 and the coffee filter 17. Also, the bowl portion 25 of the dripper 11 has a natural shape that takes into consideration the load of hot water on the coffee filter 17 when hot water is poured in. Therefore, the first rod portion 21 is less likely to bite into the inside of the coffee filter 17 into which hot water has been poured, and the shape of the coffee filter 17 is stable, preventing problems such as coffee grounds and hot water overflowing from the coffee filter 17.

[0048] The first rod portion 21 extends radially when viewed from above. That is, the first rod portion 21 may extend, for example, linearly or spirally when viewed from above. Each of the multiple folded portions 22 is disposed at the vertices of a polygon having four or more sides. As shown in FIG. 10, in this embodiment, the multiple folded portions 22 are disposed at the vertices of a quadrangle. Each of the multiple folded portions 22 is formed by bending so that the outside becomes a small-diameter arc.

[0049] Further, each of the portions of the first rod portions 21 near the folded-back portions 22 forms a side of a polygon. As shown in Fig. 10, in this embodiment, the portion 21A near the folded-back portion 22 of the first rod portion 21 forms a side of a rectangle. The bottom end of the coffee filter 17 can be reliably supported by the side of this polygon (rectangle), effectively preventing the coffee filter 17 from falling out downward. [Third embodiment]

[0050] 12 to 15, a description will be given of dripper 11 of the third embodiment. Dripper 11 of the third embodiment differs from the first embodiment in the number of connecting rods 14 and the installation angle of connecting rods 14, but other configurations are the same as those of the first embodiment.

[0051] In this embodiment, there are six connecting rods 14. That is, the connecting rods 14 are provided around the central axis S at positions shifted by 60 degrees each.

[0052] Each of the multiple connecting rods 14 has a first rod portion 21 extending from the first ring portion 12 toward approximately the central portion CA of the second ring portion 13, a folded portion 22 provided at approximately the central portion CA of the second ring portion 13, and a second rod portion 23 extending from the folded portion 22 toward the second ring portion 13.

[0053] Here, as shown in FIG. 13, a virtual cone 24 (virtual cone shape) is considered, with the first ring portion 12 as the bottom surface and the center C2 of the second ring portion 13 as the apex. The central axis of this virtual cone 24 coincides with the central axis S passing through the center C1 of the first ring portion 12 and the center C2 of the second ring portion 13. The first rod portion 21 is curved so as to be convex toward the outside O in the normal direction of the generatrix 24A of the virtual cone 24. Therefore, in the dripper 11 of this embodiment, the bowl portion 25 formed by the multiple first ring portions 12 and capable of supporting the coffee filter 17 has a shape like a downwardly convex parabola. Therefore, compared to a dripper formed in a simple cone shape, the volume of hot water that can be stored inside the coffee filter 17 attached thereto is increased. Also, by making the shape of the bowl portion 25 like a downwardly convex parabola, the area of ​​the portion of the bottom of the bowl portion 25 that is approximately horizontal is increased compared to a simple conical dripper. Therefore, when hot water is poured into the dripper, the hot water can be received at the bottom of the bowl portion 25 of the dripper 11 as much as possible, preventing the lightweight dripper 11 from falling over and the coffee filter 17 from falling off the dripper 11, and stabilizing the dripper 11 and the coffee filter 17. Also, the bowl portion 25 of the dripper 11 has a natural shape that takes into consideration the load of hot water on the coffee filter 17 when hot water is poured in. Therefore, the first rod portion 21 is less likely to bite into the inside of the coffee filter 17 into which hot water has been poured, and the shape of the coffee filter 17 is stable, preventing problems such as coffee grounds and hot water overflowing from the coffee filter 17.

[0054] The first rod portion 21 extends radially when viewed from above. That is, the first rod portion 21 may extend, for example, linearly or spirally when viewed from above. Each of the multiple folded portions 22 is disposed at the vertices of a polygon having four or more sides. As shown in FIG. 14, in this embodiment, the multiple folded portions 22 are disposed at the vertices of a hexagon. Each of the multiple folded portions 22 is formed by bending so that the outside becomes a small-diameter arc.

[0055] Moreover, each of the portions of the first rod portions 21 near the folded-back portions 22 forms a side of a polygon. As shown in Fig. 14, in this embodiment, the portion 21A near the folded-back portion 22 of the first rod portion 21 forms a side of a hexagon. The bottom end of the coffee filter 17 can be reliably supported by the side of this polygon (hexagon), effectively preventing the coffee filter 17 from falling out downward.

[0056] The above-described embodiment can be implemented with various substitutions and modifications. In addition, the above-described embodiments can be naturally combined appropriately to realize the invention. [Explanation of symbols]
