Abstract
Description
[Technical Field]
[0001] To provide a teapot and a multi-layered sheet body for a teapot, which is suitable not only for making tea by pouring hot water over tea leaves, but also for pouring hot water over ground coffee beans to extract hot coffee liquid and transferring it to a coffee cup or the like. [Background technology]
[0002] The present applicant has proposed a teapot and tea strainer for a teapot that allows for good water flow and allows the strainer to be easily attached and removed (for example, Patent Document 1). [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2004-230101 Summary of the Invention [Problem to be solved by the invention]
[0004] However, Patent Document 1 has a configuration as in claim 1, "a tea strainer (2) having a flat perforated plate (2b) or a mesh body (2a), ... with both side edges (211, 211) abutting the inner wall of the body and with the upper edge (231) appearing at the top opening 20 (O) of the teapot body," and while this is effective for tea pots, it is not suitable for use in coffee pots. If ground coffee beans (hereinafter referred to as "coffee powder") are simply "equipped with a flat perforated plate (2b) or mesh (2a)," the tea leaves can be removed, but the remaining part of the coffee powder (hereinafter referred to as "ground coffee residue") after the coffee components have been extracted from the coffee powder will pass through. If the mesh is coarse, like a tea strainer, even the ground coffee residue will pass through, while if the mesh of the perforated plate (2b) or mesh (2a) is made finer, it will quickly become clogged. In addition, to make it easier to attach and remove the tea strainer, the "strainer (2) is designed so that its upper edge (231) appears at the top opening (O) of the teapot body," but when coffee powder is poured into the teapot, it sometimes gets into the strainer through the top opening. This is not a big problem with tea leaves in a teapot for loose tea, but in the case of a teapot for coffee, if solid particles of powder or dregs get mixed in, the coffee cannot be enjoyed properly. Furthermore, the protrusions must be provided on the inner surface of the teapot body, which is time-consuming and increases the number of steps required to manufacture the teapot.
[0005] The present invention solves the above problems and aims to provide a teapot and a multi-layered sheet body for a teapot that can smoothly transfer extracted coffee liquid to a cup or the like while effectively preventing the passage of powder and dregs, and that prevents coffee powder from entering the strainer when it is placed inside the teapot body, not limited to tea. DISCLOSURE OF THE INVENTION [Means for solving the problem]
[0006] In order to achieve the above-mentioned object, the first aspect of the present invention is a teapot comprising a teapot body having a tubular spout protruding from it, surrounding a hot water inlet provided in a bottomed, cylindrical vessel having an inner rim extending from the edge of the top opening; a lid that can be attached and detached to cover the top opening of the vessel; a first metal mesh part formed in sheet form; and a second metal mesh part formed in sheet form with a larger mesh than the first mesh part and superimposed on top of it, wherein the first mesh part covers the hot water inlet, the exposed mesh surface of the second mesh part superimposed on it facing toward the inside of the teapot body, and the upper peripheral portion of the second mesh part abuts against the angular inner surface area where the tubular part related to the vessel connects to the inner rim, and the lower peripheral portion of the second mesh part abuts against the angular inner surface area where the tubular part related to the vessel connects to the bottom of the vessel, and the second mesh part is attached to the inside of the teapot body. The teapot of the second aspect of the present invention is the teapot of the first aspect, further comprising a connecting fin made of synthetic resin or rubber, which is provided in an annular shape along the peripheries of the first and second net parts, the inner periphery of which embeds and integrates the peripheries of the first and second net parts to connect the two net parts, and the outer periphery of which extends outward in a fin-like shape from both net parts over the entire periphery of both net parts, and the first net part, the second net part and the connecting fin form an integrated multi-layer sheet body, and the hot water spout is covered by the first net part. The exposed mesh surface of the second mesh portion faces the inside of the teapot body, and the upper end portion of the multilayer sheet body is abutted against the corner inner surface area where the tubular portion of the vessel connects to the inner rim, instead of the upper peripheral portion of the second mesh portion, and the lower end portion of the multilayer sheet body is abutted against the corner inner surface area where the tubular portion connects to the bottom, instead of the lower peripheral portion of the second mesh portion, so that the connecting fin is attached in close contact with the inner surface of the teapot body. A third aspect of the teapot of the present invention is the first or second aspect, characterized in that the bottom has a flat center inner surface and a peripheral portion that bulges downward, and a recess is formed in the inner corner where the inner surface of the peripheral portion connects to the lower end of the tubular portion, and the peripheral portion below the second mesh portion or the lower end of the multilayer sheet body fits into this recess.A fourth aspect of the teapot of the present invention is the second aspect, characterized in that a protruding knob is integrally molded with the connecting fin, and the multilayer sheet body attached to cover the pouring hole is positioned so that the knob protrudes from the connecting fin into the teapot body.A fourth aspect of the teapot of the present invention is the second aspect, characterized in that a protruding knob is integrally molded with the connecting fin, and the multilayer sheet body attached to cover the pouring hole is positioned so that the knob protrudes from the connecting fin into the teapot body. The teapot of a fifth aspect of the present invention is the teapot of the third aspect, characterized in that the first net portion and the second net portion have circular shapes in plan view. A sixth aspect of the present invention is a multi-layered sheet body for a teapot comprising: a first metal mesh part formed in a sheet shape; a second metal mesh part formed in a sheet shape with larger mesh than the first mesh part and an opposing mesh surface superimposed on top of the first mesh part; a connecting fin made of synthetic resin or rubber that is annularly arranged along the peripheries of the first and second net parts and has an inner peripheral portion that embeds and integrates both peripheral portions of the first and second net parts to connect the two net parts, and an outer peripheral portion that protrudes outward in a fin-like manner from both net parts around the entire periphery of both net parts; and a knob that is molded integrally with the connecting fin and is provided so as to protrude from the exposed mesh surface of the second net part that is the side opposite the opposing mesh surface, wherein the knob, the first net part, the second net part, and the connecting fin are integrated together. The seventh aspect of the present invention is a multilayer sheet body for a teapot, which is characterized in that, in the sixth aspect, the knob, the first mesh portion, the second mesh portion, and the connecting fin are integrated and have a circular shape when viewed from above.
[0007] (action) As in the first and second aspects of the present invention, the teapot comprises a first mesh section and a sheet-like second mesh section with larger mesh than the first mesh section, with the opposing mesh surface laid on top of it. When the first mesh section covers the pouring hole and the second mesh section is laid on top of it with its exposed mesh surface facing the inside of the teapot body where the top opening is, the second mesh section captures larger powdery dregs, leaving only the remaining smaller powdery dregs to be captured by the first mesh section, making it less likely to clog. It can be used for both tea and coffee. When the first mesh portion covers the hot water opening, the coffee powder will not get into the strainer portion when poured into the teapot body through the top opening. The second mesh part and the first mesh part play their respective roles, and even if a fine mesh second mesh part is used, it does not clog immediately, and since it is a teapot, the delicious coffee liquid extracted in the teapot can be passed through the second mesh part and the first mesh part in that order and transferred from the pouring outlet to a coffee cup or the like. [Effects of the Invention]
[0008] The teapot and multi-layered sheet body for a teapot of the present invention has great advantages, such as preventing coffee powder from entering the strainer when it is poured into the teapot body, and allowing the coffee liquid extracted in the teapot to be smoothly transferred from the teapot's spout to a coffee cup or the like while effectively preventing the passage of powder and dregs, and being usable for both tea and coffee.

In each figure, essential parts are emphasized for clarity, and the mesh of the first and second mesh sections is roughly illustrated in Figures 9 and 10. Furthermore, parts not directly related to the present invention are omitted.
[0011] (1) Embodiment 1 This embodiment is directed to a teapot P and a multilayer sheet body 5, which are provided with a teapot body 1, a multilayer sheet body 5, and a lid 4, as shown in FIGS. The teapot body 1 is a single unit comprising a tubular portion 21, a bottom portion 22, a spout portion 31, and a handle 32. The teapot body 2 is a cylindrical vessel with a bottom, with a stepped inner flange 219 extending from the top opening edge 201 as shown in Figure 1, and the tubular spout portion 31 protrudes from the outer surface of the tubular portion 21, surrounding a pouring port 210 provided in the tubular portion 21. The tip of the pouring portion 31 forms the pouring outlet 310. The pouring portion 31, circular bottom 22, and tubular portion 21, which has a slightly rounded cylindrical body, are integrally molded into a bottomed tubular shape using a plaster mold or the like and made of ceramic clay. In Figure 2, the tubular portion 21 and bottom 22 are shown with solid lines, and the pouring portion 31 is shown with a chain line. The bottom 22 and tubular portion 21 form the top opening 20, and an inner flange 219 on which the lid 4 is placed extends one step below the top opening edge 201. In addition, a hole is formed in part of the tubular portion 21 to form a molten metal port 210. The base end of the tubular pouring portion 31, which has an enlarged inner diameter, surrounds this molten metal port 210 and is connected to the tubular portion 21, so that hot water HW poured from the top opening 20 flows through the molten metal port 210 and toward the pouring outlet 310. Reference numeral 32 denotes a handle 32 that is attached later to protrude from the outer surface of the cylindrical portion 21, which is offset at an angle of approximately 90° from the spout portion 31 when viewed from above the teapot body 1.
[0012] In this embodiment, the bottom 22 has a flat center inner surface and a peripheral portion 221 that juts out downward, and an annular recess V is formed by the inner surface of the peripheral portion 221 and a corner inner surface region 216k of the lower end portion 216 of the tubular portion 21. Here, "below" and "above" in this invention refer to the lower and upper sides of the paper when the teapot P is placed on a table or the like, as shown in Figure 2. By forming the downwardly recessed recess V, the lower end portion 52 of the multilayer sheet 5, which will be described in detail later, abuts against the lower corner inner surface region 216k where the lower end portion 216 of the tubular portion 21 connects to the peripheral portion 221 of the bottom 22 that is connected to the vessel 2, and the multilayer sheet 5 is engaged and held in place in the teapot body 1. The upper end portion 51 of the multilayer sheet body 5 also abuts against and engages with the upper corner inner surface region 215k where the upper end portion 215 of the tubular portion 21 of the vessel 2 connects to the inner flange 219. The multilayer sheet body 5 uses the flexible and elastic upper end portions 51 and lower end portions 52 of the first net portion 6, second net portion 7, and connecting fin 8 to reliably engage and hold the area around the pouring hole 210 to the inner surface 1b of the teapot body through its elastic restoring force. The multilayer sheet body 5 is attached to the teapot body 1 so that the connecting fin 8 is in close contact with the inner surface 1b of the teapot body.
[0013] The multilayer sheet body 5 is an integrated product having a first net portion 6, a second net portion 7, and connecting fins 8 (FIGS. 3 and 4). The first mesh part 6 is a metal strainer made of stainless steel, iron, or other material, consisting of a sheet-like wire mesh with a mesh of holes woven from woven wire. It is flexible and large enough to cover the hot water opening 210 from inside the teapot body 10, and here it is circular in plan view. The first mesh part 6 has a fine mesh of 150 to 200 mesh.
[0014] The second mesh part 7 is a metallic strainer made of stainless steel, iron, or the like, which is made of a metal mesh formed into a sheet shape with the opposing mesh surface 7a superimposed on the first mesh part 6. The second mesh part 7 has larger mesh than the first mesh part 6, specifically, a mesh with a coarse mesh size of 30 to 50 mesh. The second mesh part 7 in this embodiment has a circular shape in plan view that is approximately the same as the first mesh part 6 (FIG. 3), and the first mesh part 6 and the second mesh part 7 are superimposed to facilitate the formation of the connecting fin 8.
[0015] The connecting fin 8 is provided in a ring shape in a plan view along the peripheral edges 611, 711 of the first net portion 6 and the second net portion 7, and is a flexible member made of synthetic resin or rubber whose inner peripheral portion 81 embeds and integrates the peripheral edge portions 61, 71 of the first net portion 6 and the second net portion 7 to connect the two net portions. The outer peripheral portion 82 projects outward in a fin-like shape from both the first net portion 6 and the second net portion 7 around the entire periphery, as shown in Figures 3 and 4. The connecting fins 8 here are made of silicone resin or silicone rubber, which not only provides heat resistance but also excellent adhesion to the inner surface 21b of the tubular portion of the teapot body 1. The connecting fins 8 of the multi-layer sheet further increase the degree of adhesion to the inner surface 21b of the attached tubular portion 21. In Figure 4, the thickness of the connecting fin 8 is drawn thick for ease of understanding, but in reality, the opposing mesh surfaces 6a, 7a of the first mesh part 6 and the second mesh part 7 come into contact or are close to each other. The connecting fin 8 is flattened and thinned as shown in Figures 6 and 7, and the thickness decreases towards the outer periphery tip.
[0016] In this embodiment, the connecting fin 8 and the knob 87 are integrally molded. The knob 87, which is a prismatic pin, protrudes from the exposed mesh surface 7b of the second mesh portion 7, which is the opposite side to the mesh surface 7a facing the first mesh portion 6. The knob 87, the first mesh portion 6, the second mesh portion 7, and the connecting fin 8 are integrated together. The resulting multilayer sheet body 5 has a circular shape in plan view, as shown in Figures 3 and 6. The diameter of the circle of the multilayer sheet body 5 is slightly larger than the tubular length of the tubular portion 21 (the length from the lower end of the corner inner surface region 216k to the upper end of the corner inner surface region 215k in Figure 2). The connecting fin 8 and tab 87 are formed by overlapping the opposing mesh surfaces 6a, 7a of the second net portion 7 and the first net portion 6 and setting them in a molding mold for the connecting fin 8, and then injecting resin raw material into the molding mold to mold the connecting fin 8 and tab 87 integrally with the second net portion 7 and first net portion 6. The first net portion 6, second net portion 7, connecting fin 8 and tab 87 form an integrated multilayer sheet body 5. Reference numeral 89 denotes gate marks created during molding. 2, the knob 87 is disposed on the upper end portion 51 of the multi-layer sheet body 5, but in FIG. 5, the knob 87 is attached to the teapot body 1 so that it can be seen.
[0017] The multilayer sheet body 5 is constructed separately from the teapot body 1, and when the multilayer sheet body 5 is inserted through the top opening 20, it covers the hot water inlet 210 with the exposed mesh surface 6b of the first mesh part 6, and is removably attached to the inner surface of the tubular part 21 with the exposed mesh surface 7b of the second mesh part 7 facing towards the inside 10 of the teapot body where the top opening 20 is located. Specifically, the upper end portion 51 of the multilayer sheet body 5 is abutted against the upper corner inner surface region 215k where the upper end portion 215 of the tubular portion 21 is connected to the inner flange 219. The upper edge portion 85 of the connecting fin 8 of the multilayer sheet body 5 attached in an upright state to the tubular portion 21 is abutted against the corner inner surface region 215k that is connected to the inner flange 219 as shown in Fig. 2. Also, the lower edge portion 86 of the connecting fin 8 of the multilayer sheet body 5 attached in an upright state to the tubular portion 21 is abutted against the corner inner surface region 216k of the lower end portion 216 of the tubular portion that is connected to the peripheral portion 221 of the bottom 22. The elastic deformation of the connecting fin 8, first net portion 6, and second net portion 7 caused by the abutment of the upper edge portion 85 and the lower edge portion 86 generates an elastic restoring force, causing the lower end portion 52 of the multilayer sheet body 5 to tightly contact the corner inner surface of the lower end portion 216 of the tubular portion.
[0018] Furthermore, in this embodiment, the bottom 22 has a flat center and a peripheral portion 221 that juts out downward, forming a recess V between the inner surface of the peripheral portion 221 and the inner corner of the lower end portion 216 of the tubular portion 21 (FIG. 2). In FIG. 5, the lower edge portion 86 of the connecting fin 8 attached to the multilayer sheet 5 covering the spout 210 and attached to the teapot body 1 reaches the bottom of the recess V, which is the lower end of the inner corner region 216k, and the multilayer sheet 5 is securely retained in the recess V. In FIG. 5, the tip of the lower edge portion 86 of the flexible connecting fin 8 abuts the inner corner region 216k and then bends slightly to cover the bottom peripheral portion 221. By fitting the lower edge portion 86 of the connecting fin 8 into this recess V, the multilayer sheet 5 covering the spout 210 is securely retained in the recess V and attached to the inner surface 21b of the tubular portion (inner surface 1b of the teapot body).
[0019] The upper end portion 51 of the multilayer sheet body 5 abuts against the upper corner inner surface region 215k where the tubular portion 21 connects to the inner flange 219, and the lower end portion 52 of the multilayer sheet body 5 abuts against the lower corner inner surface region 216k where the lower end portion 216 of the tubular portion 21 connects to the peripheral portion 221 of the bottom 22, so that the multilayer sheet body 5 covers the spout 210. Then, due to the elastic restoring force caused by some elastic deformation due to the abutment, the connecting fins 8 of the multilayer sheet body 5 tightly adhere to the inner surface 1b of the teapot body around the spout 210 around the annular periphery. Moreover, the tubular portion 21 around the spout 210 is approximately circular in plan view, and as the inner peripheral edge 211 of the spout 210 on the inside of the teapot moves from the center toward both ends in plan view, the multilayer sheet body 5 is elastically deformed into an arc. Due to the elastic deformation in the arc shape, the layered sheet body 5 is brought into close contact with the arc-shaped inner peripheral edge 211 of the pouring port 210 by its elastic restoring force. Thus, the upper end portion 51 and lower end portion 52 of the multilayer sheet body 5 equipped with the first mesh portion 6 and the second mesh portion 7 abut against the teapot body 1, and the connecting fins 8 are in close contact with the inner surface 1b of the teapot body 1 (more specifically, the inner corners of the upper end portion 215 and the lower end portion 216 of the cylindrical portion), so that the multilayer sheet body 5 covers the hot water opening 210 and is removably attached to the teapot body 1. When the multilayer sheet body 5 is attached to the teapot body 1, the inside 10 of the teapot body is divided into the main body portion 1A and the strainer portion 1B.
[0020] The lid 4 is literally a lid 4 that closes the top opening 20 of the vessel 2 attached to the teapot body 1. Like a normal teapot lid 4, it is disc-shaped to fit the top opening 20 and has a projection in the center of the outer surface that can be gripped by hand, and also has a through hole that allows communication with the outside air to prevent the pressure inside the teapot body 10 from decreasing when the lid 4 is placed on the teapot body 1.
[0021] Next, one way of using the teapot P will be described. First, the multilayer sheet body 5 is inserted into the teapot body 10 through the top opening 20. The exposed mesh surface 6b of the first mesh section 6 covers the hot water inlet 210, and the multilayer sheet body 5 is pressed by hand against the inner surface 21b of the tubular section 21 around the hot water inlet 210, ensuring contact around the entire periphery. The diameter of the multilayer sheet body 5, which is circular in plan view, is set slightly larger than the length of the tubular section 21. Therefore, the upper end portion 51 of the multilayer sheet body 5 can be abutted against the inner surface of the upper side corner connecting the tubular section 21 and the inner flange 219, and the lower end portion 52 of the multilayer sheet body 5 can be abutted against the inner surface of the lower side corner connecting the tubular section 21 and the bottom 22, ensuring that the multilayer sheet body 5 is engaged and abutted against the inner surface 21b of the tubular section 21. The outer periphery of the multilayer sheet body 5 is formed with adhesive connecting fins 8, which adhere tightly to the inner surface 1b of the teapot body around the entire periphery.
[0022] Next, as shown in Figure 1, coffee powder 9 is poured into bottom portion 22 through top opening 20. After that, as shown in Figure 2, hot water HW is poured into the brewer, and the extracted hot coffee liquid is poured into a cup or the like through outlet 310, allowing you to easily enjoy aromatic coffee. When the extracted coffee liquid is taken out from the spout 310, the second mesh portion 7 removes large particles of ground coffee, so the first mesh portion 6 does not quickly become clogged with ground coffee, and the coffee powder 9 can be replaced any number of times. When the clogging progresses and the teapot becomes difficult to use, the multilayered sheet body 5 is detachably attached to the teapot body 1, so the multilayered sheet body 5 can be removed by grasping the knob 87 and the ground coffee can be removed by rinsing with water, etc., and the multilayered sheet body 5 can be reused. The desired teapot P and multi-layered sheet body 5 can be used not only for tea but also for pouring hot water HW over ground coffee beans to extract aromatic coffee liquid, which can be transferred to a coffee cup or the like.
[0023] (2) Embodiment 2 This embodiment is a teapot P in which the multilayer sheet body 5 of embodiment 1 is replaced with a first mesh part 6 and a second mesh part 7 (Figs. 8 to 10). The connecting fins 8 of embodiment 1 are not present. The teapot body 1 and lid 4 are the same as those of embodiment 1, and a description thereof will be omitted. The teapot body 1, in which the cylindrical part 21, the bottom part 22 and the pouring part 31 are integrated, the first net part 6 and the second net part 7 are respectively configured as separate bodies, and the first net part 6 and the second net part 7 are detachably attached to the teapot body 1.
[0024] The first mesh part 6 is a metallic strainer made of stainless steel, iron, or the like, which is made of a wire mesh formed into a sheet shape with a mesh of holes by weaving wires (FIG. 10). Here, as in the first embodiment, it is circular in plan view. The second mesh part 7 is a metallic strainer made of stainless steel, iron, or the like, and is made of a sheet-like wire mesh with larger mesh than the first mesh part 6, on which the opposing mesh surface 7a is superimposed (FIG. 9). The second mesh part 7 is also circular in plan view, but its shape in plan view is the same as or slightly larger than that of the first mesh part 6 (FIGS. 9 and 10). In this embodiment, the first net part 6 and the second net part 7 have the same circular shape in plan view, and the diameter in plan view is the same as the circular diameter of the multilayer sheet body 5 including the connecting fin 8 in embodiment 1.
[0025] The first mesh portion 6 and the second mesh portion 7 are attached to the teapot body 1, for example, as follows. First, the hot water inlet 210 is covered with the first mesh part 6, and the exposed mesh surface 7b of the second mesh part 7, which has the opposing mesh surface 7a superimposed on the opposing mesh surface 6a of the first mesh part 6, is directed toward the inside 10 of the teapot body, which has the top opening 20. Next, the upper peripheral portions 61, 71 of the first mesh portion 6 and the second mesh portion 7 are abutted against the upper corner inner surface region 215k where the upper end portion 215 of the tubular portion 21 of the vessel 2 connects to the inner flange 219. At the same time, the lower peripheral portions 61, 71 of the first mesh portion 6 and the second mesh portion 7 are abutted against the lower corner inner surface region 216k where the lower end portion 216 of the tubular portion 21 connects to the peripheral portion 221 of the bottom 22. The elastic restoring force of the elastic deformation caused by the abutment of the first mesh portion 6 and the second mesh portion 7 causes them to engage within the teapot body 10, completing the teapot P with the first mesh portion 6 and the second mesh portion 7 attached to the teapot body inner surface 1b. Furthermore, the cylindrical portion 21 around the spout 210 is roughly circular in plan view, and as the inner peripheral edge 211 of the spout 210 on the inside of the teapot moves from the center toward both sides in plan view, the first mesh portion 6 and the second mesh portion 7 are elastically deformed into an arc shape. The restoring force associated with this elastic deformation increases the degree of adhesion of the first mesh portion 6 and the second mesh portion 7 to the inner surface 1b of the teapot body.
[0026] In this embodiment, the first mesh portion 6 and the second mesh portion 7 have the same diameter as the diameter of the multilayer sheet body 5. As shown in Figure 8, a peripheral edge 611 of the first mesh portion 6 abuts against the upper corner inner surface region 215k and the lower corner inner surface region 216k of the vessel 2. In addition, since the second mesh portion 7 also has the same diameter as the diameter of the multilayer sheet body 5, a peripheral edge 711 of the second mesh portion 7 abuts against the upper corner inner surface region 215k and the lower corner inner surface region 216k of the vessel 2. Here, first mesh portion 6 is attached to teapot body 10 by elastic deformation, for example by bulging slightly toward spout portion 31. Second mesh portion 7 is attached to teapot body 10 by elastic deformation, bulging slightly toward the center of teapot body 10 (FIG. 8). Both first mesh portion 6 and second mesh portion 7 are secured to upper end portion 215 and lower end portion 216 of tubular portion inner surface 21b by the elastic restoring force associated with elastic deformation. As in embodiment 1, a recess V is formed at the location where tubular portion 21 and bottom portion 22 are connected. By fitting peripheral portions 61 and 71 of first mesh portion 6 and second mesh portion 7 into recess V, both first mesh portion 6 and second mesh portion 7 are firmly secured and held in recess V and attached to tubular portion inner surface 21b. Incidentally, after inserting the first mesh part 6 into the recess V, it may be difficult to insert the second mesh part 7 into the recess V. In such cases, as shown in Figures 9 and 10, the diameter of the first mesh part 6 is set slightly smaller than the diameter of the second mesh part 7. The first mesh part 6 covers the spout 210, and the second mesh part 7 holds the first mesh part 6 upright, fulfilling the role of keeping it engaged within the teapot body 10, thereby eliminating the difficulty of the above-mentioned operation. The rest of the configuration of the teapot body 1, lid 4, first mesh part 6, and second mesh part 7 is the same as in embodiment 1, so a description thereof will be omitted. Thus, as in embodiment 1, by placing coffee powder 9 in the bottom 22, then pouring hot water HW into the teapot, the extracted hot coffee liquid can be poured into a coffee cup or the like through the outlet 310, resulting in the desired teapot P that allows you to easily enjoy aromatic coffee.
[0027] (3) Effects The teapot and multi-layered sheet body 5 for teapots constructed in this way comprises a first mesh portion 6 and a second mesh portion 7 formed in a sheet-like shape with larger mesh than the first mesh portion 6 and an opposing mesh surface 7a superimposed on the first mesh portion 6. The first mesh portion 6 covers the hot water inlet 210, and the second mesh portion 7 is attached with its exposed mesh surface 7b facing the inside of the teapot body 10, where the top opening 20 is located. As a result, the second mesh portion 7 captures larger powder residue remaining from the ground coffee beans, while the first mesh portion 6 only needs to capture the other smaller powder residue, making clogging less likely. It can be used for both tea and coffee. When hot water is poured over the coffee powder 9 placed on the bottom 22 and poured into the teapot body 10 through the top opening 20, it passes through the second mesh 7 and then the first mesh 6. The second mesh 7 collects and passes through the larger powder particles, while the first mesh 6 collects only the fine powder particles that slip through the second mesh 7, allowing the extracted coffee liquid to pass through and be filtered. The first mesh 6 has a finer mesh than the second mesh 7, allowing you to enjoy coffee without any impurities, with its original flavor and rich aroma. The first mesh 6 and the second mesh 7 perform their respective roles, and even though the second mesh 7 has a finer mesh, it does not easily become clogged, so the extracted delicious coffee liquid passes through the second mesh 7 and the first mesh 6 and can be transferred to a coffee cup or the like through the teapot P's outlet 310.
[0028] Hot water (HW) is poured through the top opening (20) onto the coffee powder placed inside the teapot body (10) and filtered through the second mesh (7) and first mesh (6). Large particles of grounds are collected by the second mesh (7) and passed through, while only the fine particles that slip through the second mesh (7) are collected by the first mesh (6), allowing the extracted coffee liquid to pass through and be filtered. The first mesh (6) has a finer mesh than the second mesh (7), allowing you to enjoy coffee without impurities, with its rich, original flavor and aroma. The second mesh (7) and first mesh (6) perform their respective roles, and even the finer mesh of the first mesh (6) does not easily become clogged. The extracted, delicious coffee liquid passes through the second mesh (7) and first mesh (6) in order, and can be poured into a coffee cup or the like through the spout (310). Since the pouring port 210 is covered by the first mesh portion 6, unlike Patent Document 1, when coffee powder is poured into the teapot body 10 through the top opening 20, there is no risk of the coffee powder getting into the strainer side.
[0029] As in embodiment 2, the first mesh part 6 covers the pouring hole 210, and the exposed mesh surface 7b of the second mesh part 7, which is placed on top of it, faces the inside of the teapot body 10. The upper peripheral portion 71 of the second mesh part 7 is abutted against the upper inner corner region 215k where the tubular part 21 connects to the inner flange 219, and the lower peripheral portion 71 of the second mesh part 7 is abutted against the lower inner corner region 216k where the tubular part 21 connects to the bottom 22, thereby attaching the second mesh part 7 to the inside surface 1b of the teapot body. When the second mesh part 7 is abutted against the inner surface 1b of the teapot body, it undergoes some elastic deformation and is retained in place by its elastic restoring force. Covering the pouring hole 210 with the first mesh part 6 and manually pressing the second mesh part against the inside surface of the tubular part around the pouring hole causes the second mesh parts 6 and 7 to abut against the inside surface 1b of the teapot body around the entire circumference of both mesh parts. There is no need to provide a protrusion inside the teapot body 10, which is a time-consuming and retrofitting process, as in Patent Document 1.
[0030] Furthermore, in the first embodiment, the multilayer sheet body 5, which includes connecting fins 8 as a constituent element, is abutted against the upper corner inner surface region 215k connecting the tubular portion 21 and the inner flange 219, and the multilayer sheet body 5 is abutted against the lower corner inner surface region 216k connecting the tubular portion 21 and the bottom portion 22, and this elastic restoring force allows the multilayer sheet body 5 to be fastened to the inner surface 1b of the teapot body. Because the outer periphery of the multilayer sheet body 5 is formed with adhesive connecting fins 8, the connecting fins 8 can be held in close contact with the inner surface 1b of the teapot body along its entire periphery. There is also no need to provide the protrusions described in Patent Document 1.
[0031] As in the first embodiment, when the multi-layered sheet 5 covers the hot water inlet 210 and the connecting fin 8 is attached so that it is in close contact with the inner surface 1b of the teapot body, coffee powder can be placed inside the teapot body 10 instead of tea leaves, and the water can be filtered smoothly while effectively preventing the passage of powder and dregs. Moreover, there is no need for the expense of consumables that would be incurred if a disposable filter were used. Furthermore, if a knob 87 is provided that is integrally molded with the connecting fin 8 and protrudes from the exposed mesh surface 7b of the second mesh portion 7, which is the opposite side to the opposing mesh surface 7a, it becomes easy to detachably attach the multilayer sheet body 5 to the teapot body 1.
[0032] Furthermore, as in embodiments 1 and 2, when the center of the inner surface of the bottom 22 is flattened and the peripheral portion 221 is protruding downward, and a recess V is formed by the inner surface of the peripheral portion 221 and the inner corner of the lower end portion 216 of the tubular portion 21, the connecting fin 8 and the first mesh portion 6 and second mesh portion 7 enter the recess V, thereby securely engaging and holding the multilayer sheet body 5, the first mesh portion 6 and the second mesh portion 7 to the teapot body 1.
[0033] Furthermore, when the planar shape of the multilayer sheet body 5 of embodiment 1 and the first mesh portion 6 and second mesh portion 7 of embodiment 2 is circular, they are easier to manufacture and handle. In embodiment 2, when attaching the first mesh portion 6 and second mesh portion 7 to the inside of the teapot body 10, there is no need to adjust the orientation or position of their upper or lower end portions, and they can be easily set inside the teapot body 10. Similarly, when attaching the multilayer sheet body 5 of embodiment 1 to the inside of the teapot body 10, there is no need to adjust the orientation or position of its upper end portion 51 or lower end portion 52, and they can be easily set inside the teapot body 10. In this way, the present teapot P and the multi-layered sheet body 5 for a teapot exhibit the various excellent effects described above and are extremely useful.
[0034] Furthermore, the present invention is not limited to the above-described embodiment, and the shape, size, number, material, etc. of the teapot body 1, vessel 2, tubular portion 21, spout portion 31, lid 4, multi-layer sheet body 5, first mesh portion 6, second mesh portion 7, connecting fin 8, etc. can be modified in various ways within the scope of the present invention depending on the purpose and use, and can be selected appropriately according to the use.
