- the present invention relates to a coffee dripper used for coffee drip by setting an inverted conical paper or cloth filter.
- coffee drippers There are various forms of coffee drippers. Typical examples include an open dripper using a cloth flannel filter and a type in which a filter is set on the inner surface of the dripper. Some filter meshes can be used repeatedly, and some drippers are disposable with paper filters. In this, this invention relates to the coffee dripper which sets and uses a filter on the inner surface of a dripper.
- the filter to be set is often made of disposable paper, but a cloth made as in Patent Document 1 is also commercially available.
- Typical dripper and filter shapes are trapezoidal and conical. The trapezoidal shape is called this because it looks like a trapezoid when viewed in a horizontal direction when set in the dripper.
- the commercially available coffee dripper has many contrivances in detail in addition to the above-mentioned difference in basic shape.
- the conical dripper described in the present invention is sometimes called a transmission type.
- the degree of retention of the extract that has passed through the coffee powder layer inside the dripper is low. It has a tendency to flow out relatively smoothly, and has the characteristics that it is easy to perform extraction similar to the open-type flannel filter described above.
- the filter used for the conical dripper is mainly a fan shape of 90 degrees in a flat state, and a shape with a vertex angle of 60 degrees set in the dripper.
- the opening angle of the inner surface of the dripper and the part inscribed in the filter is also approximately 60 degrees.
- the preceding conical dripper has the following problems.
- Patent document 2 is made in view of said point. Means are provided for varying the opening angle of the conical coffee dripper in contact with the filter. This makes it possible to stably perform extraction with a filter in which the vertex angle of the inverted cone is changed. It can also be used when making trapezoidal filters with an inverted cone.
- Patent Document 2 since the opening angle of the dripper is variable, a movable or deformable part that is not found in a general conventional example is required. If the configuration to be adopted is devised, it is possible to design with the aim of improving portability, storage and distribution efficiency by dividing and storing. These characteristics have so far been only for outdoor use. Applications such as automatic adjustment are also possible for orientations that emphasize ease of handling rather than instrument size.
- Patent Document 2 has a somewhat troublesome aspect in changing the opening angle of the dripper. It is necessary to remove the side plates 3 and 6 once or to disengage the base 83. In order to match the angle with the deeply folded filter, it may be necessary to repeat the adjustment in some cases, which is further troublesome.
- the present invention has been made in view of the above points. At least three frame members that are closed on at least one side are combined, and a guide is provided to maintain the shape by changing the angle between the frame members. This makes it possible to adjust the open angle of the dripper to the filter angle even with the filter attached.
- the dripper shape can be optimized with a more intuitive operation.
- the coffee dripper of the present invention makes it possible to adjust the taste according to the amount to be extracted more easily than in the past. In addition, it is possible to realize an environment in which it is easy to explore the taste of each user. Compared to the conventional method, the angle adjustment of the filter and dripper becomes easier and intuitive operation becomes possible. By providing an easy-to-understand taste adjustment method, it can be used to relieve users' weakness. Further, for example, combinations with drip pots using cups and the like described in Patent Documents 4 and 5 are also effective. In terms of drip performance, it is possible to provide a drip coffee set that has a higher degree of freedom than conventional and has excellent portability and storage. The present invention adds more controllability and mobility to drip coffee. I think it can contribute to further penetration and development of regular coffee culture.
- FIG. 6 is a diagram for explaining a storage state of the dripper of FIG.
- FIG. 9 is a diagram for explaining a storage state of the dripper of FIG. Is a top view showing another configuration of the dripper in Example 2 of the present invention
- FIG. 11 is a diagram for explaining a storage state of the dripper of FIG. Is a diagram showing a combination example of the frame members in the present invention
- FIG. 6 is an explanatory view of a response to a conventional problem.
- the actual drip methods are various, and the drip process to be premised is first outlined. As a rough process, it is often divided as follows. There are three steps: the first throw to spread the moisture to the coffee powder, the steaming process to stop the pouring and stabilize the coffee powder, and the main extraction process. Actually, each process is performed by various methods and parameters for each individual user, store, organization, and the like. It was derived based on the beliefs and tastes regarding taste and the tendency of grilled beans to be used. The wide range of taste adjustment by the drip method is also a feature of the hand drip method. For example, there is a method of pouring the filter before the first throw, and a method of starting with the filter being dry.
- the former places importance on the close contact between the dripper and the filter in the subsequent process, and the latter places importance on the diffusion of the gas generated in the process until the steaming.
- the steaming process may not be provided depending on the methodology of the preceding and following processes.
- This extraction is also various.
- the dripper is sometimes lifted up and poured while the wet coffee powder flows greatly.
- Some methodologies, including the best ones, may not apply to some methodologies, but the following explanation assumes the most common method.
- the dripper is a method of pouring hot water without touching the coffee powder while keeping it horizontal. In the process, attention is paid to the above-described extraction process. There are countless parameters and methodologies here as well.
- FIG. 14 (A) is a view showing a cross section at the center of the filter when two cups of coffee powder are put into a normal conical paper filter.
- FIG. 14B is a cross-sectional view of the same powder. 1 is a filter and 2 is coffee powder. The coffee powder is put in the same density as (A) and (B), and the volume of the coffee powder in (B) is half that of (A). The figure shows a state where the surface of the coffee powder is leveled before the drip is started. Here, the distances from the respective coffee powder surfaces to the apex of the cone are 141 and 142 indicated by broken lines. (A) Since the cone of (B) is similar, 142 is about 1.26 times the depth of 141 (one-third root of 2).
- the area of the upper surface of the coffee powder is about 1.59 times that of (A) in (B) (1/2 of the square root of 2).
- This extraction is performed using a coffee layer having the above-mentioned shape ratio as a filtration layer, assuming that it has expanded in a conical shape. If this extraction is carefully performed with a moisture content that does not overflow, the outflow from the side of the filter can be suppressed to a small amount.
- the flow resistance of the filtration layer under the conditions is considered to be about 1.26 times (depth ratio / section ratio) of (A) in (B).
- the pouring speed of (B) is half that of (A).
- the flow resistance is less than twice, the extract tends to flow out earlier than (A). This can be confirmed by a simple experiment. Due to the early spill, the moisture content of the coffee powder remains low. On the other hand, the filtration layer is shallow, and the number of coffee powder particles encountered when the extract passes through the layer is small. (B) is not exactly the same as (A). In addition, when the molten water of (B) is reduced to 1.26 times that of (A) in order to extract the water content equally, the difference in layer depth is inevitable.
- the degree of temperature drop of the hot water to be poured usually changes as the extraction time becomes shorter. Thereby, the profile of the component extracted from coffee powder also changes. It is considered that the extraction result can be approximated by reducing the pouring speed. In other words, the moisture content is lowered to make the contact between the coffee powder and the extract dense, and cover the shallowness of the layer.
- many difficulties are involved in overcoming the temperature drop and the difference in contact reaction with the powder. Many users are tricking and drip while feeling this on their skin.
- FIG. 1 is a figure which shows the structure which performs extraction of one cup on the same conditions as extraction of two cups.
- the taste adjustment described above and the drip amount correspondence mentioned in the previous section will be described in common.
- FIG. 15A is a diagram illustrating a state in which the filter 1 is folded at a narrow angle. Folding of the joint portion 151 of the filter is made deeper than usual. From the broken line indicating the original state, the circumference is folded back to about 1 / 1.41 (the square root of 2).
- FIG. 15B shows a cross section in a state where this is expanded into a cone and the same amount of coffee powder as in FIG. 14B is added.
- the depth 152 is the same as that in FIG. 14A, the area of the upper surface is 1 ⁇ 2, and the flow resistance is approximately doubled.
- the outflow speed is also halved.
- the moisture content can be changed in the same manner, and a filtration layer having the same depth as that shown in FIG. 14A can be extracted over the same time. There will be a chance to do the same extraction.
- This is also a method that can be used for the taste adjustment. For example, this is effective when the extraction in FIG. 14B using the same amount of coffee powder has an unsatisfactory taste.
- the filter 1 and the coffee powder 2 have been illustrated above, and the coffee dripper has been described without being illustrated.
- Patent Document 2 addresses this problem, but has the above-mentioned problem of usability. Except for Example 3, the side plate is an essential configuration, and most of the filter surface is along the side plate. Side outflow can be controlled to some extent by making a difference in the shape of the side plate surface and the angle between the side plate and the filter. However, the adjustment range does not reach the open state as much as Nel Drip.
- FIGS. 13A, 13 ⁇ / b> B, 13 ⁇ / b> C, and 13 ⁇ / b> D show cases where the number of frame members is 3, 4, 5, and 6, respectively.
- a central region 139 where all the frame members overlap is provided, and the frame members are crossed and combined. Assuming that the number of frame members to be used is n, there is a configuration having intersections up to the n ⁇ 1 order on the outer peripheral side in order from the central portion 139.
- (C) and (D) are numbered only at the intersection of one frame member at the top of the figure.
- One frame member intersects with other frame members (n ⁇ 1) ⁇ 2 times.
- each frame member alternately receives a deformation stress in the opposite direction at each intersection.
- a force is generated to reduce the deformation amount by increasing the distance between adjacent intersections.
- the outer peripheral portion of each figure is displaced in the direction perpendicular to the paper surface with respect to the central portion 139, and the combination of frame members rises to form a three-dimensional structure.
- One or more sets of the respective intersections 131 to 135 are held so that a line connecting the intersections of the same order forms a regular polygon parallel to the paper surface.
- Arbitrary frame members and other frame members having the same relative positional relationship in FIG. 13 all maintain the same relative positional relationship and posture in the formed structure. All the frame members straddle the center part 139 from the part facing the center part 139 and reach the outer peripheral part with the same inclination.
- the guide itself maintains the shape by forming a regular polygon parallel to the paper surface connecting each of the next intersections 131 to 135 in the circumferential direction.
- a filter holding member that connects the central portion 139 and the outer peripheral portion and does not straddle the central portion 139 is provided. It is not shown in FIG. See Example 1.
- a conical filter dripper can be configured by adjusting the inclination of the frame member to keep the relative angle between the holding members appropriate. The opening angle can be adjusted steplessly according to the folding angle of the filter. The greater the number of frame members, the more the filter can be held in a horizontal cross section that is closer to a circle. Decide on the balance between usability, appearance, and number of parts.
- the shape holding force may be generated even if the cross is not completely mesh-like as shown in FIG. This involves the shape and material of the frame member, the cross-sectional shape and the surface properties, and the conditions cannot be defined unconditionally.
- the dripper can be constructed as long as the conical shape of the filter is not greatly distorted. If the guide itself does not have a shape-retaining force that deviates from the above, there is no force to keep the filter in a normal posture, so that a separate mechanism for preventing overturning and retaining the shape is required.
- the method of the present invention can also be applied to trapezoidal drippers.
- a trapezoidal shape is realized by using an even number of frame members and facing the frame members with different shapes.
- the calculations in FIGS. 14 and 15 are not applicable, and the adjustment range is limited. It is necessary to pay attention to the difference between the assumed / recommended drip method described above.
- Many trapezoidal drippers currently on the market are supposed to be impregnated. Compared to the conical shape, the extract tends to stay in the dripper.
- a method as disclosed in Patent Document 6 is suitable. It can be expected that this method is also effective as a means for controlling the outflow described in Problem B.
- the present invention is more compatible with the concept of a transmission drip than an impregnation type. Of course, it is also possible to combine both methods.
- FIG. 1 is a perspective view showing a configuration of a dripper in Embodiment 1 of the present invention.
- Four frame wires 3 using a stainless spring material are used for the frame member constituting the guide portion.
- the filter holding part that supports the conical shape is constituted by the chain 4.
- Reference numeral 5 denotes a pedestal for setting in an extracted coffee receiving container such as a coffee server or a mug, which is also a stainless spring material.
- FIGS. 2A and 2B are projection views of the frame wire 3, in which FIG. 2A is a front view, FIG. 2B is a left view, and FIG. 2C is a schematic top view.
- the frame wire 3 is formed by bending a single wire.
- the four frame wires 3 have the same mesh-like combination as in FIG. 13B in FIG.
- the upper part of the frame wire 3 in the component state is open, it is closed by two caulking portions 26 after being combined in a mesh shape.
- the frame member is elastic around the entire circumference.
- the fitting portions 21 and 22 define the position of the portion corresponding to the primary intersection 131 in FIG.
- the fitting points are provided on the same circumference having the center on the surface 291 and symmetrically about the center surface 291 of the frame member.
- FIG. 3 showing a state in which the guide portion is spread on a plane.
- 21 is an upper cross fitting
- 22 is a lower cross fitting
- the upper cross 21 is fitted to the lower cross 22 of the adjacent frame wire 3
- the lower cross 22 is fitted to the opposite upper cross 21.
- the numbering of each part of the frame wire 3 is limited to a part in FIG.
- the fitting portions 21 and 22 are offset from the plane 292 formed by the frame wire 3.
- illustration is omitted for easy viewing. In FIG. 1, it is offset downward, and in FIG.
- the loop 25 is offset in the direction of the center axis of the dripper, and the preliminary loop 27 and the double portion 28 are offset in the direction of the dripper outer side. This offset avoids interference between the conical filter and the frame wire 3 especially when the opening angle is narrowed.
- Reference numeral 23 denotes a lower loop through which the chain 4 passes. Further, it also serves as a guide to the mating counterpart frame wire 3 to facilitate the assembly operation from the storage state described later.
- the chain 4 is lowered and tied from the upper loop 25 on the left and right of one frame wire to the lower loop 23 of the frame wire.
- the lower loop 23 has a width in the path of the chain 4, but when tension is applied, the lower loop 23 is stabilized in the shortest route near the center surface 291 in FIG.
- the chain 4 sequentially passes through the upper loop 25 and the lower loop 23 to form the eight filter holding portions 10 in the direction slightly inclined from the entire circumference of the filter and the conical generatrix.
- the interval between the loops 25 between the adjacent frame wires 3 is determined, and the opening angle of the dripper is determined.
- the end of the chain 4 is sandwiched between the double portions 28 of the frame wire 3 to fix the adjusted length.
- a separate fixture may be provided.
- FIG. 4 is a perspective view showing the configuration of the base 5.
- the pedestal 5 is configured by a single wire so that the size can be reduced by deformation. It consists of a central loop portion 46 for holding the guide portion and a wing portion 47 in contact with the receiving container.
- the central loop portion 46 has eight guide holding portions 41 that are folded slightly downward at an acute angle.
- a wing 47 is formed in the same plane through the portion 44 where the guide holding portion 41 is doubled and the intersecting portions 42, 43, and is fixed by a hook 45 on the opposite side of the central loop 46. When folded, the size can be reduced by removing the hook 45 and the intersections 42 and 43.
- the guide holding part 41 is fitted to the horizontal part 24 of the frame wire 3 in FIGS. 1 and 2A and 3 and holds the guide part.
- the horizontal portions 24 of the opposing wire frames 3 are fixed in parallel with a predetermined interval. As shown in FIG. 2A, the horizontal shaft 293 through which the horizontal portion 24 passes is above the fitting portions 21 and 22. Since the axis for changing the angle of the frame wire 3 passes through the fitting portions 21 and 22, when the opening angle of the dripper is narrowed, a stress is generated in the direction in which the interval between the opposing horizontal portions 24 widens.
- FIG. 5 is a side view showing a state in which the filter 1 is mounted on the dripper described above.
- the pedestal 5 is not shown for ease of viewing.
- FIG. 5A shows a case where three cups are extracted
- FIG. 5B shows a case where 1.5 cups are extracted.
- the length of the section 51 of the chain 4 connecting the upper loops 25 of the adjacent frame wires 3 is different between (A) and (B).
- the opening angle of the dripper is narrowly fixed by adjusting the section 51 to be short.
- the filter 1 enters a little lower than (A). Considering the case where the receiving container is shallow, the installation height fluctuation of the filter 1 due to the opening angle is reduced.
- the distance between the fitting portions 21 and 22 of each frame wire is set short.
- a configuration in which a plurality of fittings are provided and selected from several inter-fitting distances during assembly is also possible. If priority is given to the stability of filter 1 installation, such as when there is a large amount of coffee powder, select a wide inter-fitting distance.
- the section 52 of FIG. 5 is along the conical surface, whereas the section 53 is slightly separated from the conical surface. This float is actually maintained when the filter is dry before the extraction starts. However, when the filter gets wet, subtle deformation occurs and the section 53 extends along, so there is no practical problem. It is also possible to take measures such as adding a chain passing through the lower loop 23 in the opposite direction or devising the shape of the loop. There are a myriad of choices for looping and chaining.
- FIG. 1 is an example of a minimum number of parts except for the number of frame wires 3. Some parts can be added to improve usability and design.
- FIG. 6 is a perspective view showing another configuration example having the same guide portion as FIG.
- 63 is a chain hook, and the remaining part of the chain 4 is hooked on the frame wire by adjusting the opening angle. Avoid situations where the hanging chain 4 is soaked in the coffee in the receptacle.
- the circular pedestal 61 has four sliding wings 62 and enables a smarter size reduction.
- the circular pedestal has a wide range of material options if there is no problem in terms of strength and hygiene.
- a chain that sequentially connects the preliminary loop 27 of the frame wire 3 and the root portion 65 of the wing 62 may be provided. It is possible to drastically increase the stress in the direction of widening the dripper opening angle and to give the dripper a strong shape holding force.
- FIG. 7 is a view showing a state in which the frame wires are overlapped with each other until they are completely folded. It is illustrated to the extent that the overlapping structure of the frame wires 3 can be understood.
- the frame wire 3 is pulled out in all directions from the stored state to narrow the overlapping portion.
- the protrusions 31 are passed through the lower loops 23 by shifting counterclockwise, and the fitting parts 21 and 22 are fitted. After each horizontal portion 24 is fitted to the pedestal, the opening angle is narrowed and fixed with the chain 4.
- FIG. 8 is a diagram for explaining the side outflow response described in Problem B.
- the dripper side plate 8 of FIG. 8A is made of a material such as a silicon sheet and has a fan shape of slightly over 180 degrees. It is flexible and has the necessary shape retention, food hygiene safety, and heat resistance.
- Reference numeral 81 is a scale indicating the standard of the opening angle to be formed. Here, the scale from 1 cup to 4 cups is exemplified as the amount of drip.
- the side plate 8 forms a conical surface with a standard opening angle of a desired drip amount.
- FIG. 8B is a side view showing a state in which the side plate 8 and the filter 1 are mounted on the dripper. An example of extracting 1.5 cups was illustrated. Here, the side plate 8 is held by the guide portion in contact with the upper loop 25 at the upper side and the lower loop 23 at the lower side. In this state, the side plate 8 itself functions as a filter holding member. When it is assumed that the side plate 8 is used, the chain 4 may not be provided as long as the side surface 8 is held by the guide portion in the vertical range within the required dripper opening angle.
- FIG. 8B is an example in which the chain 4 is not provided. The loop is not necessary and the structure of the frame wire 3 can be simplified.
- the frame member is substantially circular, there is a space between the frame member and the filter below the upper opening of the dripper. For this reason, it is difficult to touch the filter even if the dripper is lifted by holding the guide during extraction. It has a convenient shape for checking the wetness of each part of the filter and the dripping of the extract.
- the opening angle of the cone can be 60 degrees or more.
- the filter is folded deeply on the apex side of FIG. In this case, however, the conical busbar becomes shorter on one side, so that the edge of the filter can be lowered, and the amount of powder contained is limited. Take measures such as using a large filter or stacking multiple sheets at different angles. As described above, the present embodiment shown in FIGS.
- the number of frame members may be three or more. As the number increases, the polygon formed by the upper loop becomes closer to a circle even if the opening angle is narrowed.
- the offset of the superstructure described in FIG. 2 is less necessary, and the structure of the frame member is simplified.
- the space between the upper loops is narrowed according to the number of frame members, and the shape of the lower part of the frame member and the structure of the base are devised.
- the frame member closed by crimping the stainless steel wire has been described, of course, it may be welded. Productivity can be improved if the difficulty of bending and assembly is reduced by dividing the structure at appropriate locations.
- a configuration without a pedestal is also possible if a chain or the like generates a stress that widens the opening angle of the guide portion.
- a tensile stress may be applied between the different orders of 131 to 135 while maintaining the cross-sectional shape.
- the entire dripper has a substantially spherical shape and can be placed as it is in a receiving container having a diameter equal to or smaller than the diameter of the frame member. Although the sinking into the receiving container becomes large, it can be set in a stable and free posture. Depending on the situation, such as when it is difficult to keep the receiving container level such as a rocky place, it is preferable.
- all the filter holding portions are configured by one chain 4
- the angle adjusting chain is configured differently from the holding portion, for example, the upper portion makes one round, the adjustment does not become complicated.
- fixing means other than the chain described in the previous stage is employed, a simple application in which only each holding portion is configured by a chain or the like is possible. Furthermore, it is simpler if the shape of the filter holding part is added to the frame member itself.
- the holding portion is not exactly the same angle as the holding portion by the chain 4 of the above embodiment. Design with attention to the angle formed by the holding part, the opening at the lower end, and the stabilization of the filter holding height.
- a holding portion that extends upward or downward with an appropriate size of the combined portion of the frame members is provided. This is an application in which the frame member is not circular. It is the same in that it does not become a holding part of the same angle as the holding part of the above embodiment.
- the crossing portion of the frame member When the crossing portion of the frame member is fitted in order to fix the cross-sectional shape of the guide portion at a certain horizontal position, it is not limited to the primary cross 131 and may be any order. Similarly, pay attention to the angle formed by the holding part, the opening at the lower end, and the holding height of the filter.
- FIG. 9 is a perspective view showing a configuration of a dripper in Embodiment 2 of the present invention.
- frame member of the guide portion For the frame member of the guide portion, four frame wires 93 using a stainless spring material are used.
- 95 is a pedestal comprising two parts, which is also a stainless spring material. The width of the pedestal 95 is different on the left and right in the figure, and the flat side 951 and the wide side pedestal 952 are combined and fixed to form a plane in contact with the receiving container.
- the frame wire 93 is not circular, but has a shape in which a plurality of slightly elongated ellipses are combined. Like FIG.
- Each pedestal 951, 952 has a respective end portion 96 attached rotatably to the outer periphery side of the secondary cross 132 of each frame wire 93.
- each pedestal end portion 96 is formed so that the lower side of the attachment loop extends to the outer peripheral side, and the arm portions 97 of the opposite pedestals are horizontally locked.
- the present embodiment is an example in which a special shape holding force reinforcing member is not provided in the guide portion.
- the filter is held only by the frame wire 93 without providing another member for holding the filter.
- the upper and lower portions of the frame wire 93 near the tertiary intersection 133 hold the filter at the innermost peripheral portion.
- the lower part of the frame wire 93 is smooth with a substantially constant radius of curvature, rotation of each frame wire, that is, posture change in each plane direction is likely to occur.
- the posture changes in the cone apex direction, and the guide shape is distorted.
- the shape of the frame wire 93 is devised. For example, unnecessary rotation can be suppressed by giving a geometrical accent such as slightly reducing the radius of curvature near the intersection passing through the outside.
- FIG. 10 is a diagram illustrating a storage state in which the dripper of FIG. 9 is folded.
- the vertical relationship of each intersection is not shown accurately.
- the locked state of the pedestal end 96 and the arm 97 is released, the thin pedestal 951 is passed through the wide pedestal 952, and both pedestals are inverted at the lower side. Accordingly, the linked guide portion is released from the shape maintenance of the secondary intersection 132, the thickness in the left-right direction in FIG. 9 is reduced, and the frame wire 93 becomes parallel and becomes flat.
- the inverted both pedestals 951 and 952 are also slightly spread and covered from both sides, and are folded to the size of about one frame wire 93 as a whole. Assemble in the reverse operation. All dripper members are combined together, making assembly and storage very simple.
- the filter is held at two or one place in the vertical direction.
- the upper holding is in the vicinity of the tertiary intersection 133 and moves upward as the opening angle becomes narrower.
- the guide-shaped holding force is strengthened and the change in the filter holding position is suppressed. In many cases, it can be used without problems.
- the powder may not reach the upper holding position, which may cause some inconvenience.
- the frame wire may interfere with the upper part of the filter without powder due to a change in the shape of the filter itself or external factors.
- a filter holding member is added. Of course, this can be avoided by using the dripper side plate 8 of the first embodiment, but the adjustment range of the extraction degree is limited as described above.
- the holding member is added in such a manner that the conical section is supported horizontally in a substantially circular shape or is supported by a line segment in a direction substantially parallel to the generatrix.
- An ideal frame wire 93 that closely follows a cone with various apex angles is ideal, but it is necessary to change the elliptical shape of the frame wire in accordance with the apex angle. From the top cover 94, a line connecting the lowest part of the opposite frame wire runs along the conical generatrix.
- the distance varies depending on the opening angle of the guide.
- the tensile force becomes a stress in the direction of expanding the guide, and thus there is a case where it is necessary to take care such as further strengthening the shape holding force of the guide itself.
- FIG. 11 is a top view illustrating another configuration of the second embodiment.
- the filter holding member described above is provided in a sliding manner. No stress that hinders the shape holding force of the guide.
- a slit 116 is provided at the top portion of the frame wire 113, a stainless steel thin wire 114 is passed through, and is engaged with a primary cross 131 of the opposite frame wire. Considering the storage time described later, the vertical engagement and the horizontal engagement are arranged diagonally.
- the thin wire 114 above the slit 116 is prevented from coming down downward by bending or the like. When the opening angle is wide, the thin wire 114 protrudes above the frame wire 113 to stabilize the holding above the filter.
- the frame wire 113 is a stainless spring material. Like FIG.
- the two holding members 115 are attached to the secondary intersection 132 of the frame wire 113.
- the lengths of the two opposing sides of the quadrangle formed by the secondary intersection 132 are equal and are more strictly defined than in FIG.
- the loop 1151 at the end is attached to a pedestal (not shown), the distance between the two sides is fixed, and the guide portion is erected.
- the pedestal may be anything as long as the holding material 115 can be kept parallel to be suitable for placement on the receiving container.
- the end loop 1151 is not limited to the loop, and may have another shape suitable for mounting the pedestal.
- the distance between the holding members 115 is maintained so that the secondary intersection 132 forms a quadrangle having the same length of the four sides.
- the shape of the same order intersection that is intended to spread uniformly is a regular polygon, geometrically, the circumference that is the maximum outer shape or the length of at least one side may be specified, or both may be used in combination.
- the shape of the frame wire 113 is distorted due to variations in the shape and surface properties. In this example, the distortion of the guide shape is suppressed by determining the length of all sides.
- the holding material 115 Prior to mounting the pedestal, only the length of the two sides facing each other is determined by the holding material 115 for the quadrangle formed by the secondary intersection 132.
- This quadrangle is stable in the form of a square, a rectangle having two sides of which length is determined as a short side, or a quadrangle in which the holding material 115 is almost stuck.
- the frame wire 113 With the uniform shape holding force of the frame wire 113, the frame wire 113 has resistance to deformation to a parallelogram or a quadrangle smaller than the square. With this characteristic, transition between the use state and the storage state described later can be performed with one touch.
- the fine wire 114 and the holding material 115 are attached through the two frame wires 113.
- FIG. 12 is a diagram illustrating a storage state in which the dripper of FIG. 11 is folded. The vertical relationship of each intersection is not shown accurately.
- the holding material 115 is brought closer to each other beyond the resistance of the guide portion described above from the state of FIG. 11, there is a stable point in the folded state in which the frame wire 113 is overlapped in a substantially flat plate shape. If you want to expand the usage, you can do the reverse operation, The holding material 115 can be stored and unfolded with a single touch of only a push-pull operation. The added thin wire 114 hardly protrudes from the slit 116 in the stored state.
- the structure of the pedestal portion can also be devised, and it can be stored and assembled to the same size as the previous example very easily.
- the holding member 115 can be integrated by incorporating a pedestal function.
- the use of the dripper side plate 8 of the first embodiment is also possible.
- the cross-sectional shape is maintained at the secondary intersection 132 and the width of the frame member is secured wide, a space can be secured between the frame member and the filter, particularly in the lower part. For this reason, it is difficult to touch the filter even if the dripper is lifted by holding the guide during extraction. It has a convenient shape for checking the wetness of each part of the filter and the dripping of the extract.
- the guide fixing part to the pedestal is illustrated as an example different from the first embodiment. It may be attached at the primary intersection 131. The comfort of hand-held drip and how it sinks into the receiving container will change. Actually, it is selected appropriately based on the user's drip method and compatibility with other instruments used.
- the number of frame members may be three or more. The greater the number, the closer the cross section holding the filter is to a circle. However, an even number configuration is desirable for folding similar to FIGS.
- the structure for maintaining the shape can be simplified by optimally selecting the side that determines the length and the vertex that determines the maximum outer shape.
- a one-touch folding structure is also possible.
- the opening angle of the cone can be 60 degrees or more.
- the filter is folded deeply on the apex side of FIG.
- the conical busbar becomes shorter on one side, so that the edge of the filter can be lowered, and the amount of powder contained is limited.
- the frame member and pedestal of the stainless wire may be manufactured by caulking or the like, or may be welded.
- Productivity can be improved if the difficulty of bending and assembly is reduced by dividing the structure at appropriate locations.
- Other materials that are not problematic in terms of strength, heat resistance, and food hygiene may be used.
- the frame member is divided into a material / shape suitable for strengthening the holding force as described above at the intersecting portion of the secondary intersection or higher. It is possible to achieve both simplification of configuration and productivity.
- Mass production is possible by using a material that can be integrally molded.
- the structure of the pedestal takes an optimum shape from the conditions such as the configuration of the guide portion. As long as the storage size is not concerned, it may be an integral type instead of a multi-piece configuration.

Abstract
[Problem] The conical apex angle of a conical coffee dripper of the prior art is fixed. Therefore, the amount of ground coffee and the thickness of a ground coffee layer are related, and it is difficult to make different amounts of coffee in a consistent manner. In addition, it is inconvenient to change the degree of extraction. With regard to this problem, a configuration has been proposed that allows the opening angle of an inner surface which contacts a filter to be varied and that is also suitable for divided storage and portability. However, such configuration required some work to adjust the angle. [Solution] Three or more frame members are combined with each other to provide a guide that maintains the shape thereof and that allows the angle formed by the frame members to be varied. Due to this configuration, a coffee dripper is provided that enables easy angle adjustment and that folds to be compact.
Description
本発明は、逆円錐形状の紙や布製フィルターをセットしてコーヒーのドリップに用いるコーヒードリッパーに関するものである。
The present invention relates to a coffee dripper used for coffee drip by setting an inverted conical paper or cloth filter.
コーヒーの焼き豆を挽いたコーヒー粉からコーヒー液を抽出する方法は数多い。含浸沈殿法は古来からの方法である。サイフォンやエスプレッソ、コーヒープレスやパーコレーター、ハンドドリップなどは専用の器具を用いる。それぞれの方法において、コーヒー粉とお湯または水との接触プロセスが異なる。同じ焼き豆を使用しても趣きの違うコーヒーを楽しむことができ、好みによって使い分けられている。
ハンドドリップによる抽出は、使用する専用器具が単純な部類で、比較的多くのユーザーに浸透している。コーヒードリッパーを使用する。 There are many ways to extract coffee liquor from ground coffee grounds. The impregnation precipitation method is an ancient method. Special equipment is used for siphons, espresso, coffee presses, percolators and hand drip. In each method, the contact process between coffee powder and hot water or water is different. Even if you use the same baked beans, you can enjoy different tastes of coffee, depending on your taste.
Extraction by hand drip is a simple class of specialized equipment to be used, and has permeated a relatively large number of users. Use a coffee dripper.

コーヒードリッパーにも、様々な形態がある。
布製のネルフィルターを用いる開放型のドリッパーや、ドリッパー内面にフィルターをセットするタイプが代表的である。繰り返し使用できるフィルターメッシュのものや、紙製のフィルターと共にドリッパー自体使い捨てのものもある。
本発明はこの中で、ドリッパー内面にフィルターをセットして使用するコーヒードリッパーに関する。セットするフィルターは使い捨ての紙製が多いが、特許文献1のような布製のものも市販されている。
ドリッパーおよびフィルター形状の代表的なものに、台形型と円錐型がある。台形型は、ドリッパーにセットした状態を水平方向ある向きから見ると台形に見えるためこう呼ばれる。
市販されているコーヒードリッパーは、上記の基本的な形状の違いの他、細部に多くの工夫がこらされている。コーヒー流出口の大きさや数、フィルターに内接する面のリブ形状などである。それぞれ想定または推奨するドリップの方法に応じた最適な構成をとる。
本発明で説明する円錐型ドリッパーは、透過型と呼ばれることもある。コーヒー粉の層を通過してきた抽出液をドリッパー内部に滞留させる度合いが低い。比較的すんなりと流出させる傾向にあり、前述した開放型のネルフィルターに近い抽出を行いやすい特徴をもつ。
円錐型ドリッパーに用いるフィルターは、平らな状態で90度の扇型、ドリッパーにセットして頂角が60度となる形状が主流である。ドリッパーの内面、フィルターに内接する部分の開き角度も略60度である。 There are various forms of coffee drippers.
Typical examples include an open dripper using a cloth flannel filter and a type in which a filter is set on the inner surface of the dripper. Some filter meshes can be used repeatedly, and some drippers are disposable with paper filters.
In this, this invention relates to the coffee dripper which sets and uses a filter on the inner surface of a dripper. The filter to be set is often made of disposable paper, but a cloth made as inPatent Document 1 is also commercially available.
Typical dripper and filter shapes are trapezoidal and conical. The trapezoidal shape is called this because it looks like a trapezoid when viewed in a horizontal direction when set in the dripper.
The commercially available coffee dripper has many contrivances in detail in addition to the above-mentioned difference in basic shape. The size and number of coffee outlets, and the rib shape of the surface inscribed in the filter. Each of them has an optimum configuration according to the assumed or recommended drip method.
The conical dripper described in the present invention is sometimes called a transmission type. The degree of retention of the extract that has passed through the coffee powder layer inside the dripper is low. It has a tendency to flow out relatively smoothly, and has the characteristics that it is easy to perform extraction similar to the open-type flannel filter described above.
The filter used for the conical dripper is mainly a fan shape of 90 degrees in a flat state, and a shape with a vertex angle of 60 degrees set in the dripper. The opening angle of the inner surface of the dripper and the part inscribed in the filter is also approximately 60 degrees.

上記先行の円錐型ドリッパーには、下記のような問題があった。
The preceding conical dripper has the following problems.
必要なコーヒーの抽出量に応じてコーヒー粉の量を変えると、伴ってドリッパー内のコーヒー層の厚みが変化する。異なる量を同じく抽出するのが難しい。
ユーザーがコーヒーの味を安定させられない要因は多くあるが、殆んどは注意して条件を安定化することが可能である。対してこの問題はドリッパーの形状によって決まって発生し、ユーザーの苦手意識につながりかねない。「一杯分のドリップは難しい」と多く言われる根本の問題である。 When the amount of coffee powder is changed in accordance with the required coffee extraction amount, the thickness of the coffee layer in the dripper changes accordingly. It is difficult to extract different amounts as well.
There are many factors that prevent the user from stabilizing the taste of the coffee, but most can be used to stabilize the conditions. On the other hand, this problem occurs depending on the shape of the dripper, which may lead to a weak awareness of the user. It is a fundamental problem that is often said to be "a drip full cup is difficult".

上記の問題を回避するために、フィルターを通常よりも深く折りこんで円錐の頂角を狭め、コーヒー層の厚みを増す方法が多く取られる。
この方法は、同量の抽出に際しても抽出度合いを変化させる時に有効である。
同等の含水率で抽出する条件下でコーヒー層の厚みを増すと、味が強く抽出される傾向がある。抽出液が層を通過する際に遭遇するコーヒー粉の粒子数が増加するためである。
上記対応は有効だが、市販の従来例コーヒードリッパーとの組み合わせでは使い勝手に問題がある。フィルターを狭角に折ることはできるがコーヒードリッパーの開角を変えられないためである。 In order to avoid the above problem, many methods are taken to fold the filter deeper than usual to narrow the apex angle of the cone and increase the thickness of the coffee layer.
This method is effective when changing the degree of extraction even when extracting the same amount.
When the thickness of the coffee layer is increased under the condition of extraction with the same moisture content, the taste tends to be strongly extracted. This is because the number of coffee powder particles encountered when the extract passes through the layer increases.
Although the above measures are effective, there is a problem in usability when combined with a commercially available conventional coffee dripper. This is because the filter can be folded at a narrow angle, but the opening angle of the coffee dripper cannot be changed.

特許文献2は、上記の点に鑑みなされたものである。円錐型のコーヒードリッパーのフィルターに接する部分の開き角度を可変する手段を設ける。これにより、逆円錐の頂角を変えたフィルターでの抽出を安定的に行なうことを可能にする。台形フィルターの折り方を工夫して逆円錐にする場合にも使える。
Patent document 2 is made in view of said point. Means are provided for varying the opening angle of the conical coffee dripper in contact with the filter. This makes it possible to stably perform extraction with a filter in which the vertex angle of the inverted cone is changed. It can also be used when making trapezoidal filters with an inverted cone.
多くの場合市販されているドリッパーは成形されたプラスチックや陶器などである。ユーザーが持ち運ぶ/保管するにあたってややかさばる。商品としても物流面では不利な面がある。
例えば特許文献3に示すような、主にアウトドア向けに市販されている商品ではこの問題は解決されている場合が多い。だが前述した問題の解決には至っていない。 In many cases, commercially available drippers are molded plastics, ceramics, and the like. It is a little bulky for users to carry / store. As a product, there are disadvantages in terms of logistics.
For example, this problem is often solved in products that are marketed mainly for outdoor use as shown inPatent Document 3. However, the problem described above has not been solved.

For example, this problem is often solved in products that are marketed mainly for outdoor use as shown in
特許文献2ではドリッパーの開角度を可変するため、一般的な従来例にはなかった可動もしくは変形可能な部品が必要になる。
採用する構成に工夫をこらせば、分割収納などにより可搬性や収納性、流通効率の向上を狙った設計が可能になる。こういった特性はこれまで、アウトドア用途のものにしかなかった。
器具サイズよりも取扱いの簡易性を重視する向きには、自動調整などの応用も可能である。 InPatent Document 2, since the opening angle of the dripper is variable, a movable or deformable part that is not found in a general conventional example is required.
If the configuration to be adopted is devised, it is possible to design with the aim of improving portability, storage and distribution efficiency by dividing and storing. These characteristics have so far been only for outdoor use.
Applications such as automatic adjustment are also possible for orientations that emphasize ease of handling rather than instrument size.

Applications such as automatic adjustment are also possible for orientations that emphasize ease of handling rather than instrument size.
しかしながら特許文献2で示した各実施例は、ドリッパーの開角度を変更するのにやや面倒な面があった。側板3、6をいったん取り外したり、台座83の嵌合をはずす必要がある。深く折り込んだフィルターと角度を合わせ込むのに、場合によって調整を繰り返す必要が生じかねず、さらに面倒になる。
However, each example shown in Patent Document 2 has a somewhat troublesome aspect in changing the opening angle of the dripper. It is necessary to remove the side plates 3 and 6 once or to disengage the base 83. In order to match the angle with the deeply folded filter, it may be necessary to repeat the adjustment in some cases, which is further troublesome.
本発明は、上記の点に鑑みなされたものである。
少なくとも片側が閉じた3つ以上の枠部材を組み合わせて、枠部材相互のなす角度を可変に自ら形状を保持するガイドを設ける。これにより、フィルターを装着したままの状態でもドリッパーの開角度をフィルター角度に合わせ込み可能となる。より直感的な操作で、ドリッパー形状を最適にできる。 The present invention has been made in view of the above points.
At least three frame members that are closed on at least one side are combined, and a guide is provided to maintain the shape by changing the angle between the frame members. This makes it possible to adjust the open angle of the dripper to the filter angle even with the filter attached. The dripper shape can be optimized with a more intuitive operation.

本発明のコーヒードリッパーにより従来よりも容易に、抽出する量に応じた味の調整が可能となる。またユーザー毎の好みの味を探究しやすい環境を実現できる。従来に比べ、フィルターとドリッパーの角度合わせの作業が容易になり、直感的な操作が可能になる。
わかりやすい味の調整方法を提供することで、ユーザーの苦手意識解消に役立ててゆくことができる。
また例えば特許文献4、5に挙げた、カップなどを利用するドリップポットとの組み合わせも有効である。ドリップ性能的にも従来よりも自由度の高い、極めて可搬性・収納性に優れたドリップコーヒーセットを提供できる。
本発明は、ドリップコーヒーにこれまで以上の制御性と機動性を付加するものである。レギュラーコーヒー文化のさらなる浸透と発展に貢献し得ると考える。 The coffee dripper of the present invention makes it possible to adjust the taste according to the amount to be extracted more easily than in the past. In addition, it is possible to realize an environment in which it is easy to explore the taste of each user. Compared to the conventional method, the angle adjustment of the filter and dripper becomes easier and intuitive operation becomes possible.
By providing an easy-to-understand taste adjustment method, it can be used to relieve users' weakness.
Further, for example, combinations with drip pots using cups and the like described in Patent Documents 4 and 5 are also effective. In terms of drip performance, it is possible to provide a drip coffee set that has a higher degree of freedom than conventional and has excellent portability and storage.
The present invention adds more controllability and mobility to drip coffee. I think it can contribute to further penetration and development of regular coffee culture.

まず、先行の円錐型ドリッパーの問題点を図14を参照して説明する。
First, the problems of the preceding conical dripper will be described with reference to FIG.
円錐型ドリッパーに限っても、実際のドリップ方法は千差万別であり、まず前提とするドリップ工程を概説する。おおまかな工程としては、次のように区分する場合が多い。コーヒー粉に水分を行き渡らせる第一投、注湯を止めてコーヒー粉を安定させる蒸らし工程、本抽出工程の3工程である。実際は各工程が、ユーザー個人や店舗、団体などごとに、種々の方法・パラメータで実施されている。味に関する信条や好み、使用する焼き豆の傾向をもとに導き出されたものである。ドリップの方法によって味の調整範囲が広い点が、ハンドドリップ方式の特徴でもある。
例えば、第一投前にフィルターに注湯する方法もあれば、フィルターが乾いた状態で始める方法もある。前者は後工程でのドリッパーとフィルターの密着を重視し、後者は蒸らしまでの工程で発生するガスの放散を重視する。蒸らし工程については、前後工程の方法論によっては設けない場合もある。本抽出もいろいろである。ドリッパーごと持ち上げて濡れたコーヒー粉を大きく流動させながら注湯することもある。注湯しながらポットの先端でコーヒー粉をかき混ぜるやり方もある。
優れたものも含め一部の方法論に当てはまらない場合があるが、以下の説明では最も一般的と思われる方法を前提とする。ドリッパーは水平に保った状態でコーヒー粉には触れずにお湯を注ぐ方法である。工程中では前記した本抽出の過程に注目する。
ここにも無数のパラメータと方法論がある。抽出温度、注湯スピードや粉表面内の注湯位置、さらには時間経過とともにこれらに与えるアクセントなどである。中で特に注湯スピードについては、本発明の主旨との関連が深いため必要に応じて触れる。 Even if it is limited to the conical dripper, the actual drip methods are various, and the drip process to be premised is first outlined. As a rough process, it is often divided as follows. There are three steps: the first throw to spread the moisture to the coffee powder, the steaming process to stop the pouring and stabilize the coffee powder, and the main extraction process. Actually, each process is performed by various methods and parameters for each individual user, store, organization, and the like. It was derived based on the beliefs and tastes regarding taste and the tendency of grilled beans to be used. The wide range of taste adjustment by the drip method is also a feature of the hand drip method.
For example, there is a method of pouring the filter before the first throw, and a method of starting with the filter being dry. The former places importance on the close contact between the dripper and the filter in the subsequent process, and the latter places importance on the diffusion of the gas generated in the process until the steaming. The steaming process may not be provided depending on the methodology of the preceding and following processes. This extraction is also various. The dripper is sometimes lifted up and poured while the wet coffee powder flows greatly. There is also a method of stirring coffee powder at the tip of the pot while pouring hot water.
Some methodologies, including the best ones, may not apply to some methodologies, but the following explanation assumes the most common method. The dripper is a method of pouring hot water without touching the coffee powder while keeping it horizontal. In the process, attention is paid to the above-described extraction process.
There are countless parameters and methodologies here as well. The extraction temperature, the pouring speed, the pouring position within the powder surface, and the accents given to these over time. In particular, the pouring speed is touched as necessary because it is closely related to the gist of the present invention.

図14(A)は、通常の円錐ペーパーフィルターに2杯分のコーヒー粉を入れた時のフィルター中央での断面を示す図である。図14(B)は同じ粉1杯分を入れた同断面図である。1はフィルター、2がコーヒー粉である。コーヒー粉は(A)(B)同じ密度で入れられており、(B)のコーヒー粉の体積は(A)の2分の1である。
図はドリップ開始前の、コーヒー粉表面を平らにならした状態を示す。ここにおいて、それぞれのコーヒー粉表面から円錐頂点までの距離が破線で示した141、142である。(A)(B)の円錐は相似なので141に対し142は約1.26分の1(2の3乗根分の1)の深さになる。コーヒー粉上表面の面積は、(B)において(A)の約1.59分の1(2の3乗根の2乗分の1)である。
ドリップを開始して、蒸らし工程までの段階でコーヒー粉の含水率と膨張率を同等に推移させたとする。円錐形のまま膨れたとして、本抽出はほぼ上記の形状比率をもつコーヒー層をろ過層として行われる。
本抽出を、オーバーフローしない程度の含水率で注意深く行なうと、フィルター側面からの流出を少量に抑制できる。その条件下におけるろ過層の流抵抗は、(B)において(A)の約1.26倍(深さ比率/断面比率)と考えられる。
目標の抽出量を(A)(B)同じ時間で淹れることを狙って、(B)の注湯スピードを(A)の半分にする。この場合、流抵抗が2倍に満たないため抽出液は(A)よりも早く流出しやすい傾向にある。このことは簡単な実験で確認することができる。早い流出により、コーヒー粉の含水率は低めに推移する。一方ろ過層が浅めで、抽出液が層を通過する際に遭遇するコーヒー粉の粒子数は少ない。(B)は(A)と全く同じ抽出にはならない。
また含水率を同等に抽出しようと(B)の注湯を(A)の1.26分の1にする場合も、層の深さの違いは避けられない。さらに抽出時間が短くなることにより、注ぐお湯の温度低下の度合いも通常変わってくる。これによりコーヒー粉から抽出される成分のプロファイルも変化する。
注湯スピードを落とすことで抽出結果を近づけられると考えられる。つまり含水率を下げてコーヒー粉と抽出液の接触を濃密にし、層の浅さをカバーする。が、上記同様に温度低下や粉との接触反応の差異をきれいに克服するには多くの困難が伴う。多くのユーザーは、このことを肌で感じつつ騙しだましドリップを行なっている。
実際には、半量のドリップで、半量より多めのコーヒー粉を使用することを推奨する例が多い。推奨に従ってほぼ同様の抽出結果を得ることもある程度可能ではある。ドリッパー内のコーヒー粉の一部を高く盛り上げるなどの「技」も考えられる。だが根本解決には、必要な抽出量にかかわらず常に同量のコーヒーをドリップする必要がある。 FIG. 14 (A) is a view showing a cross section at the center of the filter when two cups of coffee powder are put into a normal conical paper filter. FIG. 14B is a cross-sectional view of the same powder. 1 is a filter and 2 is coffee powder. The coffee powder is put in the same density as (A) and (B), and the volume of the coffee powder in (B) is half that of (A).
The figure shows a state where the surface of the coffee powder is leveled before the drip is started. Here, the distances from the respective coffee powder surfaces to the apex of the cone are 141 and 142 indicated by broken lines. (A) Since the cone of (B) is similar, 142 is about 1.26 times the depth of 141 (one-third root of 2). The area of the upper surface of the coffee powder is about 1.59 times that of (A) in (B) (1/2 of the square root of 2).
Suppose that the moisture content and expansion rate of coffee powder are changed equally between the start of drip and the steaming process. This extraction is performed using a coffee layer having the above-mentioned shape ratio as a filtration layer, assuming that it has expanded in a conical shape.
If this extraction is carefully performed with a moisture content that does not overflow, the outflow from the side of the filter can be suppressed to a small amount. The flow resistance of the filtration layer under the conditions is considered to be about 1.26 times (depth ratio / section ratio) of (A) in (B).
Aiming to make the target extraction amount (A) and (B) in the same time, the pouring speed of (B) is half that of (A). In this case, since the flow resistance is less than twice, the extract tends to flow out earlier than (A). This can be confirmed by a simple experiment. Due to the early spill, the moisture content of the coffee powder remains low. On the other hand, the filtration layer is shallow, and the number of coffee powder particles encountered when the extract passes through the layer is small. (B) is not exactly the same as (A).
In addition, when the molten water of (B) is reduced to 1.26 times that of (A) in order to extract the water content equally, the difference in layer depth is inevitable. Furthermore, the degree of temperature drop of the hot water to be poured usually changes as the extraction time becomes shorter. Thereby, the profile of the component extracted from coffee powder also changes.
It is considered that the extraction result can be approximated by reducing the pouring speed. In other words, the moisture content is lowered to make the contact between the coffee powder and the extract dense, and cover the shallowness of the layer. However, as described above, many difficulties are involved in overcoming the temperature drop and the difference in contact reaction with the powder. Many users are tricking and drip while feeling this on their skin.
In fact, there are many examples that recommend using half the amount of drip and more than half the amount of coffee grounds. It is possible to some extent to obtain similar extraction results according to recommendations. “Techniques” such as raising a part of the coffee powder in the dripper high can be considered. But the fundamental solution is to always drip the same amount of coffee regardless of the amount of extraction required.

次に、フィルターを通常より深く折りこむ方法と、同方法における先行ドリッパーでの問題点について図15を参照して説明する。一杯分の抽出を二杯分の抽出と同じ条件で行なう構成を示す図としてある。前述した味調整と、前項で触れたドリップ量対応とを共通に説明する。
Next, a method of folding the filter deeper than usual and problems with the preceding dripper in the method will be described with reference to FIG. It is a figure which shows the structure which performs extraction of one cup on the same conditions as extraction of two cups. The taste adjustment described above and the drip amount correspondence mentioned in the previous section will be described in common.
図15(A)は、フィルター1を狭角に折りこむ様子を示す図である。フィルターの接合部分151の折り返しを通常より深くする。もとの状態を示す破線から、円周が約1.41分の1(2の平方根分の1)になるよう折り返す。
これを円錐に広げて図14(B)と同量のコーヒー粉を入れた状態の断面が図15(B)である。ろ過層の形状比率を求めると、図14(A)に対して深さ152は同じ、上表面の面積は2分の1、流抵抗は略2倍となる。
本抽出で注湯スピードを2分の1とした時、流出スピードも2分の1になる。つまり含水率も同等で推移させることが可能で、図14(A)と同じ深さのろ過層を同じ時間をかけて抽出できる。同じ抽出を行なえるチャンスが生まれることになる。
またこれは、上記の味調整に利用できる方法でもある。例えば同量のコーヒー粉を使った図14(B)の抽出で物足りない味だった場合に行なうと有効である。
以上、フィルター1とコーヒー粉2を図示して、コーヒードリッパーは図示せずに説明した。 FIG. 15A is a diagram illustrating a state in which thefilter 1 is folded at a narrow angle. Folding of the joint portion 151 of the filter is made deeper than usual. From the broken line indicating the original state, the circumference is folded back to about 1 / 1.41 (the square root of 2).
FIG. 15B shows a cross section in a state where this is expanded into a cone and the same amount of coffee powder as in FIG. 14B is added. When the shape ratio of the filtration layer is obtained, thedepth 152 is the same as that in FIG. 14A, the area of the upper surface is ½, and the flow resistance is approximately doubled.
When the pouring speed is halved in this extraction, the outflow speed is also halved. That is, the moisture content can be changed in the same manner, and a filtration layer having the same depth as that shown in FIG. 14A can be extracted over the same time. There will be a chance to do the same extraction.
This is also a method that can be used for the taste adjustment. For example, this is effective when the extraction in FIG. 14B using the same amount of coffee powder has an unsatisfactory taste.
Thefilter 1 and the coffee powder 2 have been illustrated above, and the coffee dripper has been described without being illustrated.
これを円錐に広げて図14(B)と同量のコーヒー粉を入れた状態の断面が図15(B)である。ろ過層の形状比率を求めると、図14(A)に対して深さ152は同じ、上表面の面積は2分の1、流抵抗は略2倍となる。
本抽出で注湯スピードを2分の1とした時、流出スピードも2分の1になる。つまり含水率も同等で推移させることが可能で、図14(A)と同じ深さのろ過層を同じ時間をかけて抽出できる。同じ抽出を行なえるチャンスが生まれることになる。
またこれは、上記の味調整に利用できる方法でもある。例えば同量のコーヒー粉を使った図14(B)の抽出で物足りない味だった場合に行なうと有効である。

上記対応は有効だが、市販の従来例コーヒードリッパーとの組み合わせでは下記の問題がある。
A.狭角に折ったフィルターがコーヒードリッパーと接するのはドリッパー下方の開放部周辺だけになる。安定感に欠き、ドリップ中に転倒してしまう危険があった。またコーヒー粉の膨張などにより、折ったフィルターがドリップ中に広がってしまう心配もあった。
B.側面流出のコントロールに制限がある。
説明の前提として、本抽出を、オーバーフローしない程度の含水率で注意深く行なうことを条件とした。これによりフィルター側面からの流出を少量に抑制できる。
オーバーフローする注湯スピードは、コーヒー粉の挽き目や焙煎度合い等々により変わるため一概には規定できない。またろ過層下部での発生は把握しにくい。抽出液の流出具合とコーヒー粉表面の濡れ具合から兆候を感知しつつ、抽出してゆく。だがこれは一般に面倒で、じれったい。時間的もしくは性格的に許容できないこともある。
コーヒー粉がオーバーフローする状態の抽出では、ろ過層の流抵抗も側面流出の影響が支配的になる。図14(B)、図15(B)とも図14(A)と大差なく早い流出となり、同じ抽出は望み得ない。その場合の対応として、フィルター側面にある程度ドリッパーを密着させて側面流出をコントロールする方法が考えられる。しかし市販の従来例コーヒードリッパーではこれができない。
A.B.どちらも、フィルターを狭角に折ることはできるがコーヒードリッパーの開角を変えられないことに起因する。 The above measures are effective, but there are the following problems when combined with a commercially available conventional coffee dripper.
A. The filter folded at a narrow angle is in contact with the coffee dripper only around the open area below the dripper. There was a lack of stability and there was a risk of falling during the drip. There was also a concern that the folded filter would spread in the drip due to the expansion of the coffee powder.
B. There are restrictions on the control of side runoff.
As a premise for explanation, this extraction was performed under the condition that it is carefully performed at a moisture content that does not overflow. Thereby, the outflow from the filter side surface can be suppressed to a small amount.
The overflowing pouring speed cannot be generally specified because it varies depending on the grind level, roasting degree, etc. of the coffee powder. In addition, it is difficult to grasp the occurrence at the bottom of the filtration layer. Extracting while detecting signs from the spilled state of the extract and the wetness of the coffee powder surface. But this is generally cumbersome and frustrating. It may be unacceptable in time or character.
In the extraction with the coffee powder overflowing, the flow resistance of the filtration layer is also dominated by the side outflow. 14 (B) and FIG. 15 (B) are the same outflow as in FIG. 14 (A), and the same extraction cannot be expected. As a countermeasure for this, a method of controlling the outflow of the side surface by bringing a dripper into close contact with the filter side surface to some extent is conceivable. However, this is not possible with commercially available conventional coffee drippers.
A. B. In both cases, the filter can be folded at a narrow angle, but the opening angle of the coffee dripper cannot be changed.

特許文献2のドリッパーはこの問題に対応するが、前述した使い勝手の課題があった。
また実施例3を除いては側板が必須の構成であり、フィルター表面の多くが側板に沿う。側板表面の形状や、側板とフィルターの角度に差を持たせるなどによりある程度、側面流出はコントロールできる。だがネルドリップほどのオープン状態までには調整範囲が及ばない。 The dripper ofPatent Document 2 addresses this problem, but has the above-mentioned problem of usability.
Except for Example 3, the side plate is an essential configuration, and most of the filter surface is along the side plate. Side outflow can be controlled to some extent by making a difference in the shape of the side plate surface and the angle between the side plate and the filter. However, the adjustment range does not reach the open state as much as Nel Drip.

上述の課題を解決する本発明について説明する。本発明の枠部材がドリッパーに適したガイド部形状を保持する原理を、図13を参照して説明する。簡単のため、枠部材を全て同一の円形部材とした例である。
図13(A)、(B)、(C)、(D)はそれぞれ、枠部材が3本、4本、5本、6本の場合を示す。全ての枠部材が重なる中心部領域139を設け、枠部材どうしを交差させて組み合わせる。
使用する枠部材の本数をnとすると、中心部139から順に外周側に、nー1次までの交差を有する構成となる。(A)には1次交差131と2次交差132、(B)には131から3次交差133まで、(C)には131から4次交差134まで、(D)には131から5次交差135までがある。見やすさのため(C)、(D)には図上方の枠部材1本の交差部分にのみ番号を付した。
任意の枠部材1本に着目すると、中心部139に面した部分から順に1次から最高次交差までを経て外周部に至り、再び順に最高次から1次交差までを経て中心部139に戻る。1本の枠部材は(nー1)×2回、他の枠部材と交差する。
図13各図は、上記各交差における上下関係が順に交互になるよう網目状に組み合わせた例である。
各枠部材は各交差において、交互に逆方向の変形応力を受ける。枠部材が弾性を有する場合、隣り合う交差間の距離を長くとって変形量を低減する力が発生する。中心部139の面積拡大に制限を加えると、各図の外周部は中心部139に対して紙面垂直方向に変位し、枠部材の組み合わせは立ち上がって立体的な構造物を形成する。
各次交差131から135のうち任意の一組以上、同じ次数の各交差を結ぶ線が紙面に平行な正多角形をなすように保持する。この時各枠部材に着目すると、受ける力は全ての枠部材において同一である。任意の枠部材と、図13上で相対位置関係を同じくする他の枠部材とは、形成された構造物のなかですべて同一の相対位置関係と姿勢を保つ。
全ての枠部材は、中心部139に面する部分から中心部139を跨いで、同一の傾斜をもって外周部に至る。各次の交差131から135をそれぞれ円周方向に結ぶ紙面に平行な正多角形をなして、ガイド自ら形状を保持する。 The present invention for solving the above-described problems will be described. The principle that the frame member of the present invention maintains the guide portion shape suitable for the dripper will be described with reference to FIG. For simplicity, this is an example in which all the frame members are the same circular member.
FIGS. 13A, 13 </ b> B, 13 </ b> C, and 13 </ b> D show cases where the number of frame members is 3, 4, 5, and 6, respectively. Acentral region 139 where all the frame members overlap is provided, and the frame members are crossed and combined.
Assuming that the number of frame members to be used is n, there is a configuration having intersections up to the n−1 order on the outer peripheral side in order from thecentral portion 139. (A) primary intersection 131 and secondary intersection 132, (B) 131 to tertiary intersection 133, (C) 131 to quaternary intersection 134, (D) 131 to quintic There is an intersection 135. For ease of viewing, (C) and (D) are numbered only at the intersection of one frame member at the top of the figure.
When paying attention to one arbitrary frame member, it goes from the part facing thecentral part 139 in order from the primary to the highest order crossing to the outer peripheral part, and then returns to the central part 139 in order from the highest order to the primary crossing again. One frame member intersects with other frame members (n−1) × 2 times.
Each figure in FIG. 13 is an example in which the upper and lower relations at the respective intersections are combined in a mesh pattern so that they alternate in order.
Each frame member alternately receives a deformation stress in the opposite direction at each intersection. When the frame member has elasticity, a force is generated to reduce the deformation amount by increasing the distance between adjacent intersections. When the expansion of the area of thecentral portion 139 is restricted, the outer peripheral portion of each figure is displaced in the direction perpendicular to the paper surface with respect to the central portion 139, and the combination of frame members rises to form a three-dimensional structure.
One or more sets of therespective intersections 131 to 135 are held so that a line connecting the intersections of the same order forms a regular polygon parallel to the paper surface. If attention is paid to each frame member at this time, the force received is the same in all the frame members. Arbitrary frame members and other frame members having the same relative positional relationship in FIG. 13 all maintain the same relative positional relationship and posture in the formed structure.
All the frame members straddle thecenter part 139 from the part facing the center part 139 and reach the outer peripheral part with the same inclination. The guide itself maintains the shape by forming a regular polygon parallel to the paper surface connecting each of the next intersections 131 to 135 in the circumferential direction.
図13(A)、(B)、(C)、(D)はそれぞれ、枠部材が3本、4本、5本、6本の場合を示す。全ての枠部材が重なる中心部領域139を設け、枠部材どうしを交差させて組み合わせる。
使用する枠部材の本数をnとすると、中心部139から順に外周側に、nー1次までの交差を有する構成となる。(A)には1次交差131と2次交差132、(B)には131から3次交差133まで、(C)には131から4次交差134まで、(D)には131から5次交差135までがある。見やすさのため(C)、(D)には図上方の枠部材1本の交差部分にのみ番号を付した。
任意の枠部材1本に着目すると、中心部139に面した部分から順に1次から最高次交差までを経て外周部に至り、再び順に最高次から1次交差までを経て中心部139に戻る。1本の枠部材は(nー1)×2回、他の枠部材と交差する。
図13各図は、上記各交差における上下関係が順に交互になるよう網目状に組み合わせた例である。
各枠部材は各交差において、交互に逆方向の変形応力を受ける。枠部材が弾性を有する場合、隣り合う交差間の距離を長くとって変形量を低減する力が発生する。中心部139の面積拡大に制限を加えると、各図の外周部は中心部139に対して紙面垂直方向に変位し、枠部材の組み合わせは立ち上がって立体的な構造物を形成する。
各次交差131から135のうち任意の一組以上、同じ次数の各交差を結ぶ線が紙面に平行な正多角形をなすように保持する。この時各枠部材に着目すると、受ける力は全ての枠部材において同一である。任意の枠部材と、図13上で相対位置関係を同じくする他の枠部材とは、形成された構造物のなかですべて同一の相対位置関係と姿勢を保つ。
全ての枠部材は、中心部139に面する部分から中心部139を跨いで、同一の傾斜をもって外周部に至る。各次の交差131から135をそれぞれ円周方向に結ぶ紙面に平行な正多角形をなして、ガイド自ら形状を保持する。 The present invention for solving the above-described problems will be described. The principle that the frame member of the present invention maintains the guide portion shape suitable for the dripper will be described with reference to FIG.

Each figure in FIG. 13 is an example in which the upper and lower relations at the respective intersections are combined in a mesh pattern so that they alternate in order.
Each frame member alternately receives a deformation stress in the opposite direction at each intersection. When the frame member has elasticity, a force is generated to reduce the deformation amount by increasing the distance between adjacent intersections. When the expansion of the area of the

中心部139と外周部を結ぶ、中心部139を跨がないフィルター保持部材を設ける。図13には図示していない。実施例1を参照されたい。枠部材の傾斜を調整して保持部材相互の相対角度を適正に保つことで、円錐フィルタードリッパーを構成できる。フィルターの折り込み角度に応じて、無段階に開角度を調整できる。枠部材の数は、多いほど円形に近い水平断面でフィルターを保持できる。使い勝手や外観、部品点数との兼ね合いで決定する。
図13のように完全な網目状ではなく、上下関係が交互でない交差が含まれても形状保持力を発生する場合がある。これには枠部材の形状や材質、断面形状や表面性などが関わり、条件を一概には規定できない。フィルターの円錐形状を大きく歪めない範囲で、この場合もドリッパーを構成できる。
上記を逸脱してガイド自身が形状保持力を持たない場合、フィルターを正規の姿勢に保つ力がないため、転倒防止・形状保持のための別機構が必要になる。極端に、複数のフィルター保持部材を独立に蝶番で角度可変に配置するような構成でも同様である。前記した自動調整などに適するが、本発明の主旨からははずれる。 A filter holding member that connects thecentral portion 139 and the outer peripheral portion and does not straddle the central portion 139 is provided. It is not shown in FIG. See Example 1. A conical filter dripper can be configured by adjusting the inclination of the frame member to keep the relative angle between the holding members appropriate. The opening angle can be adjusted steplessly according to the folding angle of the filter. The greater the number of frame members, the more the filter can be held in a horizontal cross section that is closer to a circle. Decide on the balance between usability, appearance, and number of parts.
The shape holding force may be generated even if the cross is not completely mesh-like as shown in FIG. This involves the shape and material of the frame member, the cross-sectional shape and the surface properties, and the conditions cannot be defined unconditionally. In this case, the dripper can be constructed as long as the conical shape of the filter is not greatly distorted.
If the guide itself does not have a shape-retaining force that deviates from the above, there is no force to keep the filter in a normal posture, so that a separate mechanism for preventing overturning and retaining the shape is required. The same applies to a configuration in which a plurality of filter holding members are independently arranged with a hinge to be variable in angle. It is suitable for the automatic adjustment described above, but deviates from the gist of the present invention.

本発明の方法を、台形型のドリッパーに応用することも可能である。偶数の枠部材を使い、形状を他と変えた枠部材を向かい合わせて台形型を実現する。ただこの場合図14、15での計算は当てはまらず、調整範囲に制限がある。前述した想定/推奨ドリップ方法の違いに注意する必要がある。現状市販されている台形型ドリッパーは、含浸型の抽出を想定するものが多い。円錐形に比して、抽出液をドリッパー内にとどめる傾向にある。含浸型ドリップにおける抽出度合いの調整については、例えば特許文献6などに開示されているような方法が適する。同方法は、前記問題点Bで述べた流出制御の手段としても有効であることが予想できる。対して本発明は、含浸型よりも透過型ドリップの考え方になじむ。もちろん、両方法を組み合わせることも可能である。
The method of the present invention can also be applied to trapezoidal drippers. A trapezoidal shape is realized by using an even number of frame members and facing the frame members with different shapes. However, in this case, the calculations in FIGS. 14 and 15 are not applicable, and the adjustment range is limited. It is necessary to pay attention to the difference between the assumed / recommended drip method described above. Many trapezoidal drippers currently on the market are supposed to be impregnated. Compared to the conical shape, the extract tends to stay in the dripper. For adjusting the degree of extraction in the impregnated drip, for example, a method as disclosed in Patent Document 6 is suitable. It can be expected that this method is also effective as a means for controlling the outflow described in Problem B. On the other hand, the present invention is more compatible with the concept of a transmission drip than an impregnation type. Of course, it is also possible to combine both methods.
以下、図面を参照して本発明の実施例を説明する。
Embodiments of the present invention will be described below with reference to the drawings.
図1は、本発明の実施例1におけるドリッパーの構成を示す斜視図である。

ガイド部分の構成を、図2、図3もあわせて参照しながら説明する。図2は、フレームワイヤー3の投影図であり、図2(A)が正面図、図2(B)が左面図、図2(C)が上面略図である。本実施例においてフレームワイヤー3は、1本のワイヤーに曲げ加工を施して構成している。
4本のフレームワイヤー3は、図1において図13(B)と同じ網目状の組み合わせになっている。部品状態のフレームワイヤー3は上部が開いているが、網目状に組み合わせた後に2箇所のカシメ部26で閉じられる。カシメを2箇所にして2重ワイヤー部28を設けることで、全周に弾性のある枠部材としている。
嵌合部21、22は、図13(B)の1次交差131にあたる部分の位置を規定する。ガイド形状のバランスのため、枠部材のセンター面291を中心に左右対称に、また面291上に中心をもつ同一円周上に嵌合ポイントを設ける。ガイド部を平面に広げた状態を示す図3を参照されたい。21は上交差の嵌合、22は下交差の嵌合で、上交差21は隣り合うフレームワイヤー3の下交差22と、下交差22は反対隣りの上交差21と嵌合する。見やすさのため図1では、フレームワイヤー3各部の番号付けを一部に限っている。
図2(B)に示すように、嵌合部分21、22はフレームワイヤー3のなす平面292からオフセットしている。図2(C)では見やすさのため図示を省略している。図1では下方向、図3では紙面奥方向にオフセットしており、これによりガイド部を平面に広げた図3の状態で嵌合が安定している。このオフセットが、後述する収納状態からの組み立て作業の容易さに寄与する。
図13(B)の原理を忠実に再現する場合には図2(A)で見た嵌合部21、22の位置はフレームワイヤー3全体の外周円周294の上に設ける。ここではやや小さい円周295の周上に嵌合部を置き、円周294からはみ出すフレーム部分をなくしている。後述する収納時の形状サイズをコンパクトにする。
25は、チェーン4を通す上部ループであり、27は予備ループである。
図2(B)、(C)に示すように、ループ25より上方の枠部分にもオフセットがある。ループ25はドリッパーの中心軸方向に、予備ループ27と2重部28はドリッパー外側方向にそれぞれオフセットする。このオフセットにより、特に開角度を狭くした時の円錐フィルターとフレームワイヤー3の干渉を回避する。
23は、チェーン4を通す下部ループである。また嵌合相手のフレームワイヤー3をガイドして後述する収納状態からの組み立て作業を容易にする役割も兼ねる。
ここでは1本のフレームワイヤー左右の上部ループ25から向かい合わせフレームワイヤーの下部ループ23にチェーン4を下ろして結ぶ。下部ループ23はチェーン4の通り道に幅をもつが、テンションをかけると図2(A)のセンター面291近く、最短のルートで安定する。
チェーン4は、上部ループ25と下部ループ23を順次通って、フィルターの全周、円錐の母線からやや傾いた方向に8本のフィルター保持部10を形成する。チェーン4の長さを調整することで隣り合うフレームワイヤー3どうしのループ25間隔を定め、ドリッパーの開角度を決定する。チェーン4の端部はフレームワイヤー3の2重部28に挟んで、調整した長さを固定している。別途固定具を設けてもよい。 The structure of the guide portion will be described with reference to FIGS. 2A and 2B are projection views of theframe wire 3, in which FIG. 2A is a front view, FIG. 2B is a left view, and FIG. 2C is a schematic top view. In this embodiment, the frame wire 3 is formed by bending a single wire.
The fourframe wires 3 have the same mesh-like combination as in FIG. 13B in FIG. Although the upper part of the frame wire 3 in the component state is open, it is closed by two caulking portions 26 after being combined in a mesh shape. By providing the double wire portion 28 with two caulking, the frame member is elastic around the entire circumference.
The fitting portions 21 and 22 define the position of the portion corresponding to the primary intersection 131 in FIG. In order to balance the guide shape, the fitting points are provided on the same circumference having the center on the surface 291 and symmetrically about the center surface 291 of the frame member. Please refer to FIG. 3 showing a state in which the guide portion is spread on a plane. 21 is an upper cross fitting, 22 is a lower cross fitting, the upper cross 21 is fitted to the lower cross 22 of the adjacent frame wire 3, and the lower cross 22 is fitted to the opposite upper cross 21. For ease of viewing, the numbering of each part of the frame wire 3 is limited to a part in FIG.
As shown in FIG. 2B, the fitting portions 21 and 22 are offset from the plane 292 formed by the frame wire 3. In FIG. 2C, illustration is omitted for easy viewing. In FIG. 1, it is offset downward, and in FIG. 3, it is offset in the depth direction in the drawing. Thus, the fitting is stable in the state of FIG. This offset contributes to the ease of assembling work from the storage state described later.
When the principle of FIG. 13B is faithfully reproduced, the positions of the fitting portions 21 and 22 seen in FIG. 2A are provided on the outer circumference 294 of the entire frame wire 3. Here, the fitting portion is placed on the circumference of a slightly smaller circumference 295, and the frame portion protruding from the circumference 294 is eliminated. The shape size at the time of storage described later is made compact.
25 is an upper loop through which thechain 4 passes, and 27 is a spare loop.
As shown in FIGS. 2B and 2C, there is an offset in the frame portion above theloop 25 as well. The loop 25 is offset in the direction of the center axis of the dripper, and the preliminary loop 27 and the double portion 28 are offset in the direction of the dripper outer side. This offset avoids interference between the conical filter and the frame wire 3 especially when the opening angle is narrowed.
Reference numeral 23 denotes a lower loop through which the chain 4 passes. Further, it also serves as a guide to the mating counterpart frame wire 3 to facilitate the assembly operation from the storage state described later.
Here, thechain 4 is lowered and tied from the upper loop 25 on the left and right of one frame wire to the lower loop 23 of the frame wire. The lower loop 23 has a width in the path of the chain 4, but when tension is applied, the lower loop 23 is stabilized in the shortest route near the center surface 291 in FIG.
Thechain 4 sequentially passes through the upper loop 25 and the lower loop 23 to form the eight filter holding portions 10 in the direction slightly inclined from the entire circumference of the filter and the conical generatrix. By adjusting the length of the chain 4, the interval between the loops 25 between the adjacent frame wires 3 is determined, and the opening angle of the dripper is determined. The end of the chain 4 is sandwiched between the double portions 28 of the frame wire 3 to fix the adjusted length. A separate fixture may be provided.
4本のフレームワイヤー3は、図1において図13(B)と同じ網目状の組み合わせになっている。部品状態のフレームワイヤー3は上部が開いているが、網目状に組み合わせた後に2箇所のカシメ部26で閉じられる。カシメを2箇所にして2重ワイヤー部28を設けることで、全周に弾性のある枠部材としている。
嵌合部21、22は、図13(B)の1次交差131にあたる部分の位置を規定する。ガイド形状のバランスのため、枠部材のセンター面291を中心に左右対称に、また面291上に中心をもつ同一円周上に嵌合ポイントを設ける。ガイド部を平面に広げた状態を示す図3を参照されたい。21は上交差の嵌合、22は下交差の嵌合で、上交差21は隣り合うフレームワイヤー3の下交差22と、下交差22は反対隣りの上交差21と嵌合する。見やすさのため図1では、フレームワイヤー3各部の番号付けを一部に限っている。
図2(B)に示すように、嵌合部分21、22はフレームワイヤー3のなす平面292からオフセットしている。図2(C)では見やすさのため図示を省略している。図1では下方向、図3では紙面奥方向にオフセットしており、これによりガイド部を平面に広げた図3の状態で嵌合が安定している。このオフセットが、後述する収納状態からの組み立て作業の容易さに寄与する。
図13(B)の原理を忠実に再現する場合には図2(A)で見た嵌合部21、22の位置はフレームワイヤー3全体の外周円周294の上に設ける。ここではやや小さい円周295の周上に嵌合部を置き、円周294からはみ出すフレーム部分をなくしている。後述する収納時の形状サイズをコンパクトにする。
25は、チェーン4を通す上部ループであり、27は予備ループである。
図2(B)、(C)に示すように、ループ25より上方の枠部分にもオフセットがある。ループ25はドリッパーの中心軸方向に、予備ループ27と2重部28はドリッパー外側方向にそれぞれオフセットする。このオフセットにより、特に開角度を狭くした時の円錐フィルターとフレームワイヤー3の干渉を回避する。
23は、チェーン4を通す下部ループである。また嵌合相手のフレームワイヤー3をガイドして後述する収納状態からの組み立て作業を容易にする役割も兼ねる。
ここでは1本のフレームワイヤー左右の上部ループ25から向かい合わせフレームワイヤーの下部ループ23にチェーン4を下ろして結ぶ。下部ループ23はチェーン4の通り道に幅をもつが、テンションをかけると図2(A)のセンター面291近く、最短のルートで安定する。
チェーン4は、上部ループ25と下部ループ23を順次通って、フィルターの全周、円錐の母線からやや傾いた方向に8本のフィルター保持部10を形成する。チェーン4の長さを調整することで隣り合うフレームワイヤー3どうしのループ25間隔を定め、ドリッパーの開角度を決定する。チェーン4の端部はフレームワイヤー3の2重部28に挟んで、調整した長さを固定している。別途固定具を設けてもよい。 The structure of the guide portion will be described with reference to FIGS. 2A and 2B are projection views of the

上記構成のガイド部分を保持する台座5の構成を、合わせて図4を参照しながら説明する。
図4は、台座5の構成を示す斜視図である。ここでは台座5を1本のワイヤーで、変形によりサイズ縮小可能に構成している。
ガイド部を保持する中央ループ部分46と、受け容器に接するウィング部分47からなる。中央ループ部分46に、下方にやや鋭角に折り込んだガイド保持部41を8箇所有する。ガイド保持部41が2重になる部分44と交差部分42、43を経て、ウィング47を同一平面内に形成して、中央ループ46対辺側にフック45で止められる。畳む時にはフック45、交差42、43を外してサイズを縮小できる。ウィング部分47に滑り止めのコーティングやカバーを施せば使い勝手が向上する。
ガイド保持部41は、図1および図2(A)、図3フレームワイヤー3の水平部24と嵌合して、ガイド部分を保持する。対向するワイヤーフレーム3の水平部24どうしを平行に、間隔を規定して固定する。図2(A)に示すように、水平部24が通る水平軸293は嵌合部21、22よりも上方にある。フレームワイヤー3の角度変更の軸は嵌合部21、22を通るため、ドリッパーの開角度を狭めると対向する水平部24どうしの間隔は広がる方向に応力を生ずる。ガイド保持部41で水平部24の間隔を一定以下に固定することで逆に、ドリッパー開角度を広げる方向に応力を発生する。この応力は前記したチェーン4の狭角方向のテンションと拮抗し、所望の開角度でガイド部分の形状保持力を高める。 The configuration of thepedestal 5 holding the guide portion having the above configuration will be described with reference to FIG.
FIG. 4 is a perspective view showing the configuration of thebase 5. Here, the pedestal 5 is configured by a single wire so that the size can be reduced by deformation.
It consists of a central loop portion 46 for holding the guide portion and awing portion 47 in contact with the receiving container. The central loop portion 46 has eight guide holding portions 41 that are folded slightly downward at an acute angle. A wing 47 is formed in the same plane through the portion 44 where the guide holding portion 41 is doubled and the intersecting portions 42, 43, and is fixed by a hook 45 on the opposite side of the central loop 46. When folded, the size can be reduced by removing the hook 45 and the intersections 42 and 43. Use of a non-slip coating or cover on the wing portion 47 improves usability.
Theguide holding part 41 is fitted to the horizontal part 24 of the frame wire 3 in FIGS. 1 and 2A and 3 and holds the guide part. The horizontal portions 24 of the opposing wire frames 3 are fixed in parallel with a predetermined interval. As shown in FIG. 2A, the horizontal shaft 293 through which the horizontal portion 24 passes is above the fitting portions 21 and 22. Since the axis for changing the angle of the frame wire 3 passes through the fitting portions 21 and 22, when the opening angle of the dripper is narrowed, a stress is generated in the direction in which the interval between the opposing horizontal portions 24 widens. On the contrary, stress is generated in the direction of widening the dripper opening angle by fixing the distance between the horizontal portions 24 to a certain value or less by the guide holding portion 41. This stress antagonizes the tension in the narrow angle direction of the chain 4 described above, and enhances the shape retaining force of the guide portion at a desired opening angle.
図4は、台座5の構成を示す斜視図である。ここでは台座5を1本のワイヤーで、変形によりサイズ縮小可能に構成している。
ガイド部を保持する中央ループ部分46と、受け容器に接するウィング部分47からなる。中央ループ部分46に、下方にやや鋭角に折り込んだガイド保持部41を8箇所有する。ガイド保持部41が2重になる部分44と交差部分42、43を経て、ウィング47を同一平面内に形成して、中央ループ46対辺側にフック45で止められる。畳む時にはフック45、交差42、43を外してサイズを縮小できる。ウィング部分47に滑り止めのコーティングやカバーを施せば使い勝手が向上する。
ガイド保持部41は、図1および図2(A)、図3フレームワイヤー3の水平部24と嵌合して、ガイド部分を保持する。対向するワイヤーフレーム3の水平部24どうしを平行に、間隔を規定して固定する。図2(A)に示すように、水平部24が通る水平軸293は嵌合部21、22よりも上方にある。フレームワイヤー3の角度変更の軸は嵌合部21、22を通るため、ドリッパーの開角度を狭めると対向する水平部24どうしの間隔は広がる方向に応力を生ずる。ガイド保持部41で水平部24の間隔を一定以下に固定することで逆に、ドリッパー開角度を広げる方向に応力を発生する。この応力は前記したチェーン4の狭角方向のテンションと拮抗し、所望の開角度でガイド部分の形状保持力を高める。 The configuration of the

図5は、以上説明したドリッパーにフィルター1を装着した状態を示す側面図である。見やすさのため台座5は図示していない。例えば図5(A)は3杯分、図5(B)は1.5杯分抽出する場合を示す。
隣接するフレームワイヤー3の上部ループ25どうしを結ぶチェーン4の区間51の長さが(A)と(B)とで異なっている。(B)では区間51を短く調整することでドリッパーの開角度を狭く固定している。
(B)では(A)よりもフィルター1はやや下方まで入り込む。受け容器が浅い場合などを考慮して、開角度によるフィルター1の設置高さ変動を緩和している。フィルター1の下方への入り込み量の差は嵌合部21と22の間の距離に比例するので、各フレームワイヤーの嵌合部21と22の間の距離を短めに設定する。嵌合を複数段設けて、組み立て時にいくつかの嵌合間距離から選択する構成も可能である。コーヒー粉量が多い場合など、フィルター1の装着安定度を優先する場合は広い嵌合間距離を選ぶ。
下部ループ23を通過する前後のチェーン4は、図5の区間52が円錐面に沿うのに対し区間53がやや円錐面から離れる。抽出開始前、フィルターが乾燥した状態では実際にこの浮きが保たれる。ただフィルターが濡れてくると微妙な変形が生じて区間53にも沿うようになり、実用上の問題はない。下部ループ23を逆向きにくぐるチェーンを追加したり、ループの形状構成を工夫するなど、対応をとることも可能である。ループの設け方とチェーンの通し方には、無数の選択肢がある。 FIG. 5 is a side view showing a state in which thefilter 1 is mounted on the dripper described above. The pedestal 5 is not shown for ease of viewing. For example, FIG. 5A shows a case where three cups are extracted, and FIG. 5B shows a case where 1.5 cups are extracted.
The length of thesection 51 of the chain 4 connecting the upper loops 25 of the adjacent frame wires 3 is different between (A) and (B). In (B), the opening angle of the dripper is narrowly fixed by adjusting the section 51 to be short.
In (B), thefilter 1 enters a little lower than (A). Considering the case where the receiving container is shallow, the installation height fluctuation of the filter 1 due to the opening angle is reduced. Since the difference in the amount of penetration below the filter 1 is proportional to the distance between the fitting portions 21 and 22, the distance between the fitting portions 21 and 22 of each frame wire is set short. A configuration in which a plurality of fittings are provided and selected from several inter-fitting distances during assembly is also possible. If priority is given to the stability of filter 1 installation, such as when there is a large amount of coffee powder, select a wide inter-fitting distance.
In thechain 4 before and after passing through the lower loop 23, the section 52 of FIG. 5 is along the conical surface, whereas the section 53 is slightly separated from the conical surface. This float is actually maintained when the filter is dry before the extraction starts. However, when the filter gets wet, subtle deformation occurs and the section 53 extends along, so there is no practical problem. It is also possible to take measures such as adding a chain passing through the lower loop 23 in the opposite direction or devising the shape of the loop. There are a myriad of choices for looping and chaining.
隣接するフレームワイヤー3の上部ループ25どうしを結ぶチェーン4の区間51の長さが(A)と(B)とで異なっている。(B)では区間51を短く調整することでドリッパーの開角度を狭く固定している。
(B)では(A)よりもフィルター1はやや下方まで入り込む。受け容器が浅い場合などを考慮して、開角度によるフィルター1の設置高さ変動を緩和している。フィルター1の下方への入り込み量の差は嵌合部21と22の間の距離に比例するので、各フレームワイヤーの嵌合部21と22の間の距離を短めに設定する。嵌合を複数段設けて、組み立て時にいくつかの嵌合間距離から選択する構成も可能である。コーヒー粉量が多い場合など、フィルター1の装着安定度を優先する場合は広い嵌合間距離を選ぶ。
下部ループ23を通過する前後のチェーン4は、図5の区間52が円錐面に沿うのに対し区間53がやや円錐面から離れる。抽出開始前、フィルターが乾燥した状態では実際にこの浮きが保たれる。ただフィルターが濡れてくると微妙な変形が生じて区間53にも沿うようになり、実用上の問題はない。下部ループ23を逆向きにくぐるチェーンを追加したり、ループの形状構成を工夫するなど、対応をとることも可能である。ループの設け方とチェーンの通し方には、無数の選択肢がある。 FIG. 5 is a side view showing a state in which the

図1の構成は、フレームワイヤー3の本数を除き最低限の部品点数からなる例である。多少部品を追加して使い勝手とデザイン性を改善することもできる。図6は、図1と同一のガイド部分を有する他の構成例を示す斜視図である。
ここにおいて63はチェーンフックで、開角度調整で余った部分のチェーン4をフレームワイヤーに引っ掛ける。垂れたチェーン4が受け容器のコーヒーに浸かるような事態を避ける。
円形台座61はスライド式のウィング62を4本有し、よりスマートなサイズの縮小を可能にする。図4のガイド保持部41と同一の位置関係でガイド部分を保持するスリット64を4箇所もつ。円形台座は、強度的・衛生的に問題がなければ材質の選択肢が広い。やや複雑なワイヤー組み合わせ部分の削減・目隠しにもつながり、全体のデザイン性の向上をもたらす。
図示しないが、フレームワイヤー3の予備ループ27とウィング62の根元部分65を順次結ぶチェーンを設けても良い。ドリッパー開角度を広げる方向の応力を格段に増してドリッパーにより強固な形状保持力を持たせることが可能になる。 The configuration of FIG. 1 is an example of a minimum number of parts except for the number offrame wires 3. Some parts can be added to improve usability and design. FIG. 6 is a perspective view showing another configuration example having the same guide portion as FIG.
Here, 63 is a chain hook, and the remaining part of thechain 4 is hooked on the frame wire by adjusting the opening angle. Avoid situations where the hanging chain 4 is soaked in the coffee in the receptacle.
Thecircular pedestal 61 has four sliding wings 62 and enables a smarter size reduction. There are four slits 64 for holding the guide portion in the same positional relationship as the guide holding portion 41 in FIG. The circular pedestal has a wide range of material options if there is no problem in terms of strength and hygiene. It also leads to reduction and blindfolding of slightly complicated wire combinations, and improves overall design.
Although not shown, a chain that sequentially connects thepreliminary loop 27 of the frame wire 3 and the root portion 65 of the wing 62 may be provided. It is possible to drastically increase the stress in the direction of widening the dripper opening angle and to give the dripper a strong shape holding force.
ここにおいて63はチェーンフックで、開角度調整で余った部分のチェーン4をフレームワイヤーに引っ掛ける。垂れたチェーン4が受け容器のコーヒーに浸かるような事態を避ける。

チェーン4をゆるめ台座を取り外してフレームワイヤーを平面に広げた図3の状態から、外周部をやや紙面奥方向に押しながら、嵌合部21、22の嵌合をはずす。続いてそれぞれのフレームワイヤーを時計回りにずらして、嵌合していた相手の下部ループ23に突起部分31をくぐらせる。これにより各フレームワイヤー3は、隣りの下部ループ23にガイドされながら比較的自由に重なることができるようになる。図7は、完全に畳んだ時近くまでフレームワイヤーを互いに重ねた状態の図である。フレームワイヤー3どうしの重なり構造がわかる程度で図示している。実際には全体でほぼフレームワイヤー3単体の径になる程度まで重ねることができる。
図6で示した円形台座61とウィング62も、このサイズにおさめることが可能である。
組み立て時は上記と逆である。収納状態からフレームワイヤー3を四方に引き出して重なり部分を狭める。反時計回りにずらして各下部ループ23に突起部31をくぐらせ、嵌合部21、22を嵌合させる。各水平部24を台座に嵌合させた後、開角度を狭めてチェーン4で固定する。 A method of folding the dripper will be described with reference to FIGS.
From the state of FIG. 3 in which thechain 4 is loosened and the pedestal is removed and the frame wire is flattened, the fitting portions 21 and 22 are unfitted while pushing the outer peripheral portion slightly toward the back of the drawing. Subsequently, each frame wire is shifted clockwise, and the protruding portion 31 is passed through the mating lower loop 23. Thus, the frame wires 3 can be relatively freely overlapped while being guided by the adjacent lower loop 23. FIG. 7 is a view showing a state in which the frame wires are overlapped with each other until they are completely folded. It is illustrated to the extent that the overlapping structure of the frame wires 3 can be understood. Actually, it can be piled up to the extent that the entire diameter of the frame wire 3 becomes substantially the whole.
Thecircular pedestal 61 and the wing 62 shown in FIG. 6 can also be accommodated in this size.
At the time of assembly, it is the reverse of the above. Theframe wire 3 is pulled out in all directions from the stored state to narrow the overlapping portion. The protrusions 31 are passed through the lower loops 23 by shifting counterclockwise, and the fitting parts 21 and 22 are fitted. After each horizontal portion 24 is fitted to the pedestal, the opening angle is narrowed and fixed with the chain 4.

図8は、問題点Bで述べた側面流出対応を説明する図である。
図8(A)のドリッパー側板8はシリコンシート等の材質で構成され、180度強の扇型をなす。柔軟で必要な形状保持力と食品衛生上の安全性、耐熱性を有する。81は形成する開角度の目安を示す目盛で、ここではドリップする量で1杯から4杯までの目盛を例示した。扇型の端部82を所望の目盛81に沿わせて、外周を揃えて巻いた時に、側板8は所望のドリップ量の標準開角度の円錐面をなす。
図8(B)は側板8とフィルター1をドリッパーに装着した状態を示す側面図である。1.5杯分の抽出を行なう場合を例示した。
ここで側板8は、上方で上部ループ25に、下方で下部ループ23に接してガイド部に保持されている。
この状態では側板8自身がフィルター保持部材として機能する。側板8の使用を前提とする場合には、必要なドリッパー開角度の範囲で側面8が上下でガイド部に保持されれば、チェーン4を装備しなくてもよい。図8(B)は、チェーン4を装備しない例である。ループは必要なくなり、フレームワイヤー3の構造も簡略化できる。(図では簡略化していない。)
本実施例では、チェーン4のテンションでガイド部の形状保持力を強化する例を説明したが、これは必須ではない。嵌合部21、22の位置、フレームワイヤー3の断面積や断面形状、表面の摩擦係数に工夫を加えて実用的な保持力を得ることもできる。またはより積極的に段差や噛み合いなどによる固定手段を設ける方法もある。ガイド部自身が均等な形状保持力を有するので、固定手段は必ずしも全ての枠部材に設けなくてもよい。1箇所での固定も可能である。図8(B)に他の強化策は図示していない。
チェーン等でガイド部に側板8以外のフィルター保持部材を装備すれば、側板8を使用しない場合も含めて抽出度合いの調整範囲を広く確保できる。 FIG. 8 is a diagram for explaining the side outflow response described in Problem B. FIG.
Thedripper side plate 8 of FIG. 8A is made of a material such as a silicon sheet and has a fan shape of slightly over 180 degrees. It is flexible and has the necessary shape retention, food hygiene safety, and heat resistance. Reference numeral 81 is a scale indicating the standard of the opening angle to be formed. Here, the scale from 1 cup to 4 cups is exemplified as the amount of drip. When the fan-shaped end portion 82 is wound along the desired scale 81 and the outer periphery thereof is aligned, the side plate 8 forms a conical surface with a standard opening angle of a desired drip amount.
FIG. 8B is a side view showing a state in which theside plate 8 and the filter 1 are mounted on the dripper. An example of extracting 1.5 cups was illustrated.
Here, theside plate 8 is held by the guide portion in contact with the upper loop 25 at the upper side and the lower loop 23 at the lower side.
In this state, theside plate 8 itself functions as a filter holding member. When it is assumed that the side plate 8 is used, the chain 4 may not be provided as long as the side surface 8 is held by the guide portion in the vertical range within the required dripper opening angle. FIG. 8B is an example in which the chain 4 is not provided. The loop is not necessary and the structure of the frame wire 3 can be simplified. (It is not simplified in the figure.)
In this embodiment, the example in which the shape holding force of the guide portion is reinforced by the tension of thechain 4 has been described, but this is not essential. Practical holding force can be obtained by modifying the positions of the fitting portions 21 and 22, the cross-sectional area and cross-sectional shape of the frame wire 3, and the friction coefficient of the surface. Alternatively, there is a method of more actively providing a fixing means by a step or engagement. Since the guide part itself has a uniform shape holding force, the fixing means may not necessarily be provided on all the frame members. Fixing in one place is also possible. FIG. 8 (B) does not show other reinforcement measures.
If the guide portion is equipped with a filter holding member other than theside plate 8 with a chain or the like, a wide adjustment range of the extraction degree can be secured including the case where the side plate 8 is not used.
図8(A)のドリッパー側板8はシリコンシート等の材質で構成され、180度強の扇型をなす。柔軟で必要な形状保持力と食品衛生上の安全性、耐熱性を有する。81は形成する開角度の目安を示す目盛で、ここではドリップする量で1杯から4杯までの目盛を例示した。扇型の端部82を所望の目盛81に沿わせて、外周を揃えて巻いた時に、側板8は所望のドリップ量の標準開角度の円錐面をなす。
図8(B)は側板8とフィルター1をドリッパーに装着した状態を示す側面図である。1.5杯分の抽出を行なう場合を例示した。
ここで側板8は、上方で上部ループ25に、下方で下部ループ23に接してガイド部に保持されている。
この状態では側板8自身がフィルター保持部材として機能する。側板8の使用を前提とする場合には、必要なドリッパー開角度の範囲で側面8が上下でガイド部に保持されれば、チェーン4を装備しなくてもよい。図8(B)は、チェーン4を装備しない例である。ループは必要なくなり、フレームワイヤー3の構造も簡略化できる。(図では簡略化していない。)
本実施例では、チェーン4のテンションでガイド部の形状保持力を強化する例を説明したが、これは必須ではない。嵌合部21、22の位置、フレームワイヤー3の断面積や断面形状、表面の摩擦係数に工夫を加えて実用的な保持力を得ることもできる。またはより積極的に段差や噛み合いなどによる固定手段を設ける方法もある。ガイド部自身が均等な形状保持力を有するので、固定手段は必ずしも全ての枠部材に設けなくてもよい。1箇所での固定も可能である。図8(B)に他の強化策は図示していない。

本実施例では枠部材を略円形としているため、ドリッパーの上部開口から下方において枠部材とフィルターの間に空間がある。そのため抽出中ガイド部を持ってドリッパーを持ち上げてもフィルターに手は触れにくい。フィルター各部の濡れ具合や抽出液の滴下をチェックするにも好都合な形状になっている。
円錐の開角度を60度以上にもできる。この場合これまでの説明と逆にフィルターを、図15(A)の頂点側において深く折り込む。ただこの場合円錐の母線が片側短くなるのでフィルターの縁に低い方向ができ、粉の収容量が制限される。大きなフィルターを使うか、角度を変えて複数枚重ねるなどの対応をとる。
以上、図1・図6に示す本実施例を中心に説明したが、他の構成の選択肢も広い。
枠部材は3本以上何本でも良い。本数が多いほど、開角度を狭くしても上部ループのなす多角形は円形に近くなる。図2で説明した上部構造のオフセットは必要性が低くなり、枠部材の構造は簡略になる。枠部材の本数に応じて上部ループの間隔を狭め、枠部材下部の形状と台座の構成を工夫する。
ステンレスワイヤーをかしめて閉じた枠部材を説明したが、もちろん溶接してもよい。適切な箇所で分割構造にして曲げ加工や組み立ての難易度を下げれば、生産性を向上できる。強度・耐熱・食品衛生上問題ない他の材質でも良い。分割構成として2次交差以上の交差部分を前記した保持力強化に適した材質・形状にする方法もある。構成の単純化と生産性の両立が可能である。一体成形できる材質にすれば大量生産もできる。
衛生面や使用・洗浄後の排水性を考慮してチェーンを採用したが、強度・耐熱・食品衛生上問題ない紐、帯状の部材であれば使用できる。柔軟なものであれば、簡易的な結びによる固定など使い勝手の幅も広がる。
またチェーン切れなど緊急時には、手近なひも等で代用できる。
ガイド部の開角度を広げる応力をチェーン等で発生すれば、台座のない構成も可能である。断面形状を保持しつつ、前記131から135の異なる次数の交差間に引っ張り応力をかければよい。前記したように枠部材のみで実用的な形状保持力を得る場合も同様である。ドリッパー全体が略球形となり、枠部材の径以下の受け容器にはそのまま置くことができる。受け容器内への沈みは大きくなるが、安定して自由な姿勢にセットできる。岩場など受け容器の水平を保つことが困難な場合など状況によっては却って好適である。ドリッパーの転倒防止や水平支持を補助する突起や取手などを設けても良い。
1本のチェーン4で全てのフィルター保持部を構成する例を示したが、チェーン切れ時の非常使用を想定すると各保持部に別のチェーンを設ける考え方もある。この場合角度調整用のチェーンは上部を1周させる等、保持部とは別の構成にすれば調整が煩雑にならない。前段で述べたチェーン以外の固定手段を採用すれば、各保持部のみをチェーン等で構成するシンプルな応用も可能である。
さらに、枠部材自身にフィルター保持部の形状を付加すればよりシンプルである。本実施例における略円形の枠部材内側に枠部材の一部として保持部を設ける方法がある。ただ上記実施例のチェーン4による保持部と全く同じ角度の保持部にはならない。保持部のなす角度と下端部の開口、フィルターの保持高さの安定化に注意して設計する。枠部材の組み合わせ部分を適切なサイズにして上方または下方に延長した保持部を設ける構成もある。これは枠部材が円形でない応用である。上記実施例の保持部と全く同じ角度の保持部にはならない点は同じである。ガイド部の、ある水平位置での断面形状を固定するために枠部材の交差部分を嵌合等させる場合、それは1次交差131に限らず何次でも構わない。同様に保持部のなす角度と下端部の開口、フィルターの保持高さの安定化に注意する。 In this embodiment, since the frame member is substantially circular, there is a space between the frame member and the filter below the upper opening of the dripper. For this reason, it is difficult to touch the filter even if the dripper is lifted by holding the guide during extraction. It has a convenient shape for checking the wetness of each part of the filter and the dripping of the extract.
The opening angle of the cone can be 60 degrees or more. In this case, the filter is folded deeply on the apex side of FIG. In this case, however, the conical busbar becomes shorter on one side, so that the edge of the filter can be lowered, and the amount of powder contained is limited. Take measures such as using a large filter or stacking multiple sheets at different angles.
As described above, the present embodiment shown in FIGS. 1 and 6 has been mainly described, but there are a wide range of other configuration options.
The number of frame members may be three or more. As the number increases, the polygon formed by the upper loop becomes closer to a circle even if the opening angle is narrowed. The offset of the superstructure described in FIG. 2 is less necessary, and the structure of the frame member is simplified. The space between the upper loops is narrowed according to the number of frame members, and the shape of the lower part of the frame member and the structure of the base are devised.
Although the frame member closed by crimping the stainless steel wire has been described, of course, it may be welded. Productivity can be improved if the difficulty of bending and assembly is reduced by dividing the structure at appropriate locations. Other materials that are not problematic in terms of strength, heat resistance, and food hygiene may be used. As a divided configuration, there is a method in which the intersecting portion of the secondary intersection or more is made into a material and shape suitable for the above-described holding power enhancement. It is possible to achieve both simplification of configuration and productivity. Mass production is possible by using a material that can be integrally molded.
The chain has been adopted in consideration of hygiene and drainage after use / washing, but any string or belt-like member with no problem in strength, heat resistance and food hygiene can be used. If it is flexible, the range of ease of use such as fixing with simple knots will be expanded.
In the event of an emergency such as a chain break, you can substitute a string that is close to you.
A configuration without a pedestal is also possible if a chain or the like generates a stress that widens the opening angle of the guide portion. A tensile stress may be applied between the different orders of 131 to 135 while maintaining the cross-sectional shape. The same applies to the case where a practical shape holding force is obtained only by the frame member as described above. The entire dripper has a substantially spherical shape and can be placed as it is in a receiving container having a diameter equal to or smaller than the diameter of the frame member. Although the sinking into the receiving container becomes large, it can be set in a stable and free posture. Depending on the situation, such as when it is difficult to keep the receiving container level such as a rocky place, it is preferable. You may provide the protrusion, handle, etc. which assist dripping fall prevention and horizontal support.
Although an example in which all the filter holding portions are configured by onechain 4 has been shown, there is a concept of providing a separate chain for each holding portion assuming an emergency use when the chain is broken. In this case, if the angle adjusting chain is configured differently from the holding portion, for example, the upper portion makes one round, the adjustment does not become complicated. If fixing means other than the chain described in the previous stage is employed, a simple application in which only each holding portion is configured by a chain or the like is possible.
Furthermore, it is simpler if the shape of the filter holding part is added to the frame member itself. There is a method of providing a holding portion as a part of the frame member inside the substantially circular frame member in the present embodiment. However, the holding portion is not exactly the same angle as the holding portion by thechain 4 of the above embodiment. Design with attention to the angle formed by the holding part, the opening at the lower end, and the stabilization of the filter holding height. There is also a configuration in which a holding portion that extends upward or downward with an appropriate size of the combined portion of the frame members is provided. This is an application in which the frame member is not circular. It is the same in that it does not become a holding part of the same angle as the holding part of the above embodiment. When the crossing portion of the frame member is fitted in order to fix the cross-sectional shape of the guide portion at a certain horizontal position, it is not limited to the primary cross 131 and may be any order. Similarly, pay attention to the angle formed by the holding part, the opening at the lower end, and the holding height of the filter.
円錐の開角度を60度以上にもできる。この場合これまでの説明と逆にフィルターを、図15(A)の頂点側において深く折り込む。ただこの場合円錐の母線が片側短くなるのでフィルターの縁に低い方向ができ、粉の収容量が制限される。大きなフィルターを使うか、角度を変えて複数枚重ねるなどの対応をとる。

図9は、本発明の実施例2におけるドリッパーの構成を示す斜視図である。
ガイド部の枠部材には、ステンレスバネ材を用いた4本のフレームワイヤー93を使用している。フレームワイヤー93のつなぎ部分をカバーして弾力性を確保するトップカバー94を最外周の頂点部分に有する。95は2部品からなる台座で、これもステンレスバネ材である。台座95は図の左右で幅が異なっており、細い側の台座951と広い側の台座952を組み合わせて固定し、受け容器に接する平面を構成している。
フレームワイヤー93は円形ではなく、やや縦長の楕円を複数合成した形状である。図13(B)同様、網目状に組み合わされている。各台座951、952はそれぞれの端部96を、各フレームワイヤー93の2次交差132外周側に回動可能に取り付けられている。図では明確でないが、各台座端部96は取付けループの下方が外周側に広がって形成されており、相対する台座のアーム部分97を水平にロックする。 FIG. 9 is a perspective view showing a configuration of a dripper inEmbodiment 2 of the present invention.
For the frame member of the guide portion, fourframe wires 93 using a stainless spring material are used. A top cover 94 that covers the connecting portion of the frame wire 93 to ensure elasticity is provided at the outermost vertex portion. 95 is a pedestal comprising two parts, which is also a stainless spring material. The width of the pedestal 95 is different on the left and right in the figure, and the flat side 951 and the wide side pedestal 952 are combined and fixed to form a plane in contact with the receiving container.
Theframe wire 93 is not circular, but has a shape in which a plurality of slightly elongated ellipses are combined. Like FIG. 13B, they are combined in a mesh shape. Each pedestal 951, 952 has a respective end portion 96 attached rotatably to the outer periphery side of the secondary cross 132 of each frame wire 93. Although not clearly shown in the figure, each pedestal end portion 96 is formed so that the lower side of the attachment loop extends to the outer peripheral side, and the arm portions 97 of the opposite pedestals are horizontally locked.
ガイド部の枠部材には、ステンレスバネ材を用いた4本のフレームワイヤー93を使用している。フレームワイヤー93のつなぎ部分をカバーして弾力性を確保するトップカバー94を最外周の頂点部分に有する。95は2部品からなる台座で、これもステンレスバネ材である。台座95は図の左右で幅が異なっており、細い側の台座951と広い側の台座952を組み合わせて固定し、受け容器に接する平面を構成している。
フレームワイヤー93は円形ではなく、やや縦長の楕円を複数合成した形状である。図13(B)同様、網目状に組み合わされている。各台座951、952はそれぞれの端部96を、各フレームワイヤー93の2次交差132外周側に回動可能に取り付けられている。図では明確でないが、各台座端部96は取付けループの下方が外周側に広がって形成されており、相対する台座のアーム部分97を水平にロックする。 FIG. 9 is a perspective view showing a configuration of a dripper in

本実施例は、ガイド部に特別な形状保持力の強化部材を設けない例である。図9ではフィルター保持の別部材も設けず、フレームワイヤー93のみでフィルターを保持する。フレームワイヤー93の3次交差133付近の上方と、下方は最内周部分でフィルターを保持する。調整によっては、上方部分のみで保持する使い方もできる。
2次交差132の配置を固定するので、ガイドの開角度に応じて最内周部分の断面積が変化する。開角度が狭まると最内周部分は小さくなり、フィルター頂角による落ち込み量変化の低減に寄与する。
フレームワイヤー93下部はほぼ一定の曲率半径で滑らかなため、各フレームワイヤーの回転、つまり各々の平面方向の姿勢変化が生じやすい。回転による傾きが大きくなり各交差部分が曲率半径の異なる部分に達すると、円錐頂角方向の姿勢変化が生じ、ガイド形状に歪みが出る。この点を考慮し、図示しないがフレームワイヤー93の形状に工夫を加える。例えば外側を通る交差近辺の曲率半径を微妙に小さくするなど形状的なアクセントを与えることで、無用な回転を抑制できる。 The present embodiment is an example in which a special shape holding force reinforcing member is not provided in the guide portion. In FIG. 9, the filter is held only by theframe wire 93 without providing another member for holding the filter. The upper and lower portions of the frame wire 93 near the tertiary intersection 133 hold the filter at the innermost peripheral portion. Depending on the adjustment, it is possible to use only the upper part.
Since the arrangement of thesecondary intersection 132 is fixed, the cross-sectional area of the innermost peripheral portion changes according to the opening angle of the guide. When the opening angle is narrowed, the innermost peripheral portion becomes smaller, which contributes to a reduction in the amount of sagging caused by the filter apex angle.
Since the lower part of theframe wire 93 is smooth with a substantially constant radius of curvature, rotation of each frame wire, that is, posture change in each plane direction is likely to occur. When the inclination due to rotation increases and each crossing portion reaches a portion having a different radius of curvature, the posture changes in the cone apex direction, and the guide shape is distorted. In consideration of this point, although not shown, the shape of the frame wire 93 is devised. For example, unnecessary rotation can be suppressed by giving a geometrical accent such as slightly reducing the radius of curvature near the intersection passing through the outside.
2次交差132の配置を固定するので、ガイドの開角度に応じて最内周部分の断面積が変化する。開角度が狭まると最内周部分は小さくなり、フィルター頂角による落ち込み量変化の低減に寄与する。
フレームワイヤー93下部はほぼ一定の曲率半径で滑らかなため、各フレームワイヤーの回転、つまり各々の平面方向の姿勢変化が生じやすい。回転による傾きが大きくなり各交差部分が曲率半径の異なる部分に達すると、円錐頂角方向の姿勢変化が生じ、ガイド形状に歪みが出る。この点を考慮し、図示しないがフレームワイヤー93の形状に工夫を加える。例えば外側を通る交差近辺の曲率半径を微妙に小さくするなど形状的なアクセントを与えることで、無用な回転を抑制できる。 The present embodiment is an example in which a special shape holding force reinforcing member is not provided in the guide portion.

The locked state of thepedestal end 96 and the arm 97 is released, the thin pedestal 951 is passed through the wide pedestal 952, and both pedestals are inverted at the lower side. Accordingly, the linked guide portion is released from the shape maintenance of the secondary intersection 132, the thickness in the left-right direction in FIG. 9 is reduced, and the frame wire 93 becomes parallel and becomes flat. The inverted both pedestals 951 and 952 are also slightly spread and covered from both sides, and are folded to the size of about one frame wire 93 as a whole.

前述したように本例は、上下方向2箇所もしくは1箇所でフィルターを保持する。そのうち上方の保持は3次交差133近辺であり、開角度が狭くなると上方に移動する。実施例1に比してフレームワイヤー93下部の曲率半径を小さくすることで、ガイド形状の保持力強化と共に、フィルター保持位置の変化を抑制している。多くの場合、問題なく使える。
狭角に折り込んだフィルターに少量のコーヒー粉しか入れず、上記上方保持位置まで粉が届かない状況でやや不便が生ずることがある。ドリップ中フィルターが濡れてくると、フィルター自身の形状変化や外的要因で粉のないフィルター上方とフレームワイヤーが干渉することがある。歪んだフィルターがコーヒー粉を覆ったり座屈する可能性もなくはない。
上記を想定する場合は、フィルター保持部材を追加する。もちろん実施例1のドリッパー側板8を使用しても回避できるが、前述したように抽出度合いの調整範囲が限られてくる。
円錐断面を水平に略円形で支えるか、円錐の略母線方向の線分で支える形で保持部材を追加する。種々の頂角をもつ円錐にぴったり寄り沿うフレームワイヤー93が理想だが、頂角に応じてフレームワイヤーの楕円形状を変化させる必要がある。
トップカバー94から、向かいのフレームワイヤー最下部を結ぶ線が円錐の母線に沿う。ここを結ぶ場合、ガイドの開角度によって距離が変わる点に注意する。弾性部材を使用すると、引っ張り力がガイドを広げる方向の応力になるため、ガイド自身の形状保持力をさらに強化するなどの手当てが必要な場合がある。
トップカバー94から下方、フレームワイヤー93に平行に弱い弾性部材を伸ばす方法もある。フィルターに押されてならう格好になるが、この時もガイドを広げる力が働く。 As described above, in this example, the filter is held at two or one place in the vertical direction. Among them, the upper holding is in the vicinity of thetertiary intersection 133 and moves upward as the opening angle becomes narrower. By reducing the radius of curvature of the lower portion of the frame wire 93 as compared to the first embodiment, the guide-shaped holding force is strengthened and the change in the filter holding position is suppressed. In many cases, it can be used without problems.
When a small amount of coffee powder is put into the filter folded at a narrow angle, the powder may not reach the upper holding position, which may cause some inconvenience. When the filter gets wet during drip, the frame wire may interfere with the upper part of the filter without powder due to a change in the shape of the filter itself or external factors. There is no possibility that a distorted filter covers or buckles the coffee powder.
When the above is assumed, a filter holding member is added. Of course, this can be avoided by using thedripper side plate 8 of the first embodiment, but the adjustment range of the extraction degree is limited as described above.
The holding member is added in such a manner that the conical section is supported horizontally in a substantially circular shape or is supported by a line segment in a direction substantially parallel to the generatrix. Anideal frame wire 93 that closely follows a cone with various apex angles is ideal, but it is necessary to change the elliptical shape of the frame wire in accordance with the apex angle.
From thetop cover 94, a line connecting the lowest part of the opposite frame wire runs along the conical generatrix. When connecting here, note that the distance varies depending on the opening angle of the guide. When an elastic member is used, the tensile force becomes a stress in the direction of expanding the guide, and thus there is a case where it is necessary to take care such as further strengthening the shape holding force of the guide itself.
There is also a method of extending a weak elastic member downward from thetop cover 94 and parallel to the frame wire 93. Although it is dressed by being pushed by the filter, the power to spread the guide works at this time as well.

図11は、実施例2の別の構成を示す上面図である。上記したフィルター保持部材をスライド式で設けている。ガイドの形状保持力を阻害する応力を生じない。
フレームワイヤー113のトップ部分にスリット116を設け、ステンレスの細ワイヤー114を通し、向かいのフレームワイヤーの1次交差131に係合させている。後述する収納時を考慮して、縦係合と横係合を対角に配す。図示していないがスリット116上方の細ワイヤー114は、折り曲げ等で下方への抜け止めを施してある。開角度が広い時には細ワイヤー114がフレームワイヤー113よりも上方に出て、フィルター上方の保持を安定にする。
フレームワイヤー113はステンレスバネ材である。図13(B)同様、網目状に組み合わされている。フィルター保持部材の装備を前提に、上方までフレーム幅を確保して保持の安定と手持ち使用の快適を優先する形状としている。回転の抑制については、前の例と同様、曲率半径のアクセントで安定させる。
2つの保持材115はフレームワイヤー113の2次交差132に取付けられる。2次交差132のなす四角形の対向する2辺の長さを等しく、図9よりも厳格に規定する。端部のループ1151を図示しない台座に取付けて2辺間の距離を固定し、ガイド部を正立させる。台座は、受け容器への載置に適して保持材115を平行に保てればどのようなものでもよい。端部ループ1151も、ループに限らず台座取付けに適する別の形状でもよい。2次交差132が、4辺の長さの等しい四角形をなすよう保持材115間の距離を保つ。
均一に広がろうとする同一次数交差の形状を正多角形にする場合、幾何学的には最大外形となる円周を規定または最低1辺の長さを規定、もしくは両者を併用すれば良い。ただ現実にはフレームワイヤー113の形状や表面性ばらつき等で形状に歪みが生ずる。この例では、全辺の長さを決定することでガイド形状の歪みを抑制する。
台座取付け前、2次交差132のなす四角形は保持材115により対向する2辺の長さのみが決められている。この四角形は、正方形または長さの決められた2辺を短辺とする長方形、または保持材115が略くっついて潰れた四角形に安定する。フレームワイヤー113の均一な形状保持力で、平行四辺形や前記正方形より小さな四角形状への変形には抵抗力を持つ。この特性により、使用状態と後述する収納状態との間の移行がワンタッチで可能となる。
細ワイヤー114、保持材115は2本のフレームワイヤー113を通して取付ける。使用中あるいは後述する収納時、取付け部が交差をくぐって取付け場所がずれる面倒が発生しない。
図12は、図11のドリッパーをたたんだ収納状態を示す図である。各交差の上下関係は、正確には示されていない。図11の状態から前記したガイド部の抵抗力を越えて保持材115を互いに近づけると、フレームワイヤー113がほぼ平板状に重なった折り畳み状態にまた安定点がある。使用状態に広げる場合は逆の操作をすればよく、
保持材115の押し引き操作のみのワンタッチで収納・展開できる。
追加した細ワイヤー114は収納状態ではほとんどスリット116から突出しない。台座部分の構成にも工夫が可能であり、非常に簡便に、先の例と同じ程度のサイズに収納・組立てできる。保持材115に台座機能を盛り込んで一体化することもできる。
もちろん実施例1のドリッパー側板8の使用も可能である。
本例では2次交差132で断面形状を保持し、かつ枠部材の幅を広く確保しているため、特に下方において枠部材とフィルターの間に空間が確保できる。そのため抽出中ガイド部を持ってドリッパーを持ち上げてもフィルターに手は触れにくい。フィルター各部の濡れ具合や抽出液の滴下をチェックするにも好都合な形状になっている。 FIG. 11 is a top view illustrating another configuration of the second embodiment. The filter holding member described above is provided in a sliding manner. No stress that hinders the shape holding force of the guide.
Aslit 116 is provided at the top portion of the frame wire 113, a stainless steel thin wire 114 is passed through, and is engaged with a primary cross 131 of the opposite frame wire. Considering the storage time described later, the vertical engagement and the horizontal engagement are arranged diagonally. Although not shown, the thin wire 114 above the slit 116 is prevented from coming down downward by bending or the like. When the opening angle is wide, the thin wire 114 protrudes above the frame wire 113 to stabilize the holding above the filter.
Theframe wire 113 is a stainless spring material. Like FIG. 13B, they are combined in a mesh shape. Based on the premise of the filter holding member, the frame width is secured to the top, giving it a shape that gives priority to stable holding and comfortable use on hand. As with the previous example, rotation suppression is stabilized with an accent of the radius of curvature.
The two holdingmembers 115 are attached to the secondary intersection 132 of the frame wire 113. The lengths of the two opposing sides of the quadrangle formed by the secondary intersection 132 are equal and are more strictly defined than in FIG. The loop 1151 at the end is attached to a pedestal (not shown), the distance between the two sides is fixed, and the guide portion is erected. The pedestal may be anything as long as the holding material 115 can be kept parallel to be suitable for placement on the receiving container. The end loop 1151 is not limited to the loop, and may have another shape suitable for mounting the pedestal. The distance between the holding members 115 is maintained so that the secondary intersection 132 forms a quadrangle having the same length of the four sides.
In the case where the shape of the same order intersection that is intended to spread uniformly is a regular polygon, geometrically, the circumference that is the maximum outer shape or the length of at least one side may be specified, or both may be used in combination. In reality, however, the shape of theframe wire 113 is distorted due to variations in the shape and surface properties. In this example, the distortion of the guide shape is suppressed by determining the length of all sides.
Prior to mounting the pedestal, only the length of the two sides facing each other is determined by the holdingmaterial 115 for the quadrangle formed by the secondary intersection 132. This quadrangle is stable in the form of a square, a rectangle having two sides of which length is determined as a short side, or a quadrangle in which the holding material 115 is almost stuck. With the uniform shape holding force of the frame wire 113, the frame wire 113 has resistance to deformation to a parallelogram or a quadrangle smaller than the square. With this characteristic, transition between the use state and the storage state described later can be performed with one touch.
Thefine wire 114 and the holding material 115 are attached through the two frame wires 113. During use or at the time of storage, which will be described later, there is no trouble that the mounting portion passes through the intersection and the mounting location shifts.
FIG. 12 is a diagram illustrating a storage state in which the dripper of FIG. 11 is folded. The vertical relationship of each intersection is not shown accurately. When the holdingmaterial 115 is brought closer to each other beyond the resistance of the guide portion described above from the state of FIG. 11, there is a stable point in the folded state in which the frame wire 113 is overlapped in a substantially flat plate shape. If you want to expand the usage, you can do the reverse operation,
The holdingmaterial 115 can be stored and unfolded with a single touch of only a push-pull operation.
The addedthin wire 114 hardly protrudes from the slit 116 in the stored state. The structure of the pedestal portion can also be devised, and it can be stored and assembled to the same size as the previous example very easily. The holding member 115 can be integrated by incorporating a pedestal function.
Of course, the use of thedripper side plate 8 of the first embodiment is also possible.
In this example, since the cross-sectional shape is maintained at thesecondary intersection 132 and the width of the frame member is secured wide, a space can be secured between the frame member and the filter, particularly in the lower part. For this reason, it is difficult to touch the filter even if the dripper is lifted by holding the guide during extraction. It has a convenient shape for checking the wetness of each part of the filter and the dripping of the extract.
フレームワイヤー113のトップ部分にスリット116を設け、ステンレスの細ワイヤー114を通し、向かいのフレームワイヤーの1次交差131に係合させている。後述する収納時を考慮して、縦係合と横係合を対角に配す。図示していないがスリット116上方の細ワイヤー114は、折り曲げ等で下方への抜け止めを施してある。開角度が広い時には細ワイヤー114がフレームワイヤー113よりも上方に出て、フィルター上方の保持を安定にする。
フレームワイヤー113はステンレスバネ材である。図13(B)同様、網目状に組み合わされている。フィルター保持部材の装備を前提に、上方までフレーム幅を確保して保持の安定と手持ち使用の快適を優先する形状としている。回転の抑制については、前の例と同様、曲率半径のアクセントで安定させる。
2つの保持材115はフレームワイヤー113の2次交差132に取付けられる。2次交差132のなす四角形の対向する2辺の長さを等しく、図9よりも厳格に規定する。端部のループ1151を図示しない台座に取付けて2辺間の距離を固定し、ガイド部を正立させる。台座は、受け容器への載置に適して保持材115を平行に保てればどのようなものでもよい。端部ループ1151も、ループに限らず台座取付けに適する別の形状でもよい。2次交差132が、4辺の長さの等しい四角形をなすよう保持材115間の距離を保つ。
均一に広がろうとする同一次数交差の形状を正多角形にする場合、幾何学的には最大外形となる円周を規定または最低1辺の長さを規定、もしくは両者を併用すれば良い。ただ現実にはフレームワイヤー113の形状や表面性ばらつき等で形状に歪みが生ずる。この例では、全辺の長さを決定することでガイド形状の歪みを抑制する。
台座取付け前、2次交差132のなす四角形は保持材115により対向する2辺の長さのみが決められている。この四角形は、正方形または長さの決められた2辺を短辺とする長方形、または保持材115が略くっついて潰れた四角形に安定する。フレームワイヤー113の均一な形状保持力で、平行四辺形や前記正方形より小さな四角形状への変形には抵抗力を持つ。この特性により、使用状態と後述する収納状態との間の移行がワンタッチで可能となる。

以上、ガイド部の自己形状保持力のみ利用する実施例2を説明した。実施例1よりも簡易な構造と操作性を得ることができる。台座へのガイド固定箇所を実施例1と変えて例示した。1次交差131で取付けてもよい。手持ちドリップの快適さや受け容器への沈み込みの具合が変わってくる。実際には使用者のドリップ作法や使用する他の器具との相性などから適切に選択する。
枠部材は3本以上何本でも良い。本数が多いほど、フィルターを保持する断面は円形に近くなる。ただし、図10、12同様の折りたたみには偶数本構成が望ましい。正多角形の規定はやや複雑になるが、長さを決める辺と最大外形を決める頂点を最適に選択して形状保持のための構造を簡略化できる。前例同様ワンタッチの折り畳み構造も可能である。
円錐の開角度を60度以上にもできる。この場合これまでの説明と逆にフィルターを、図15(A)の頂点側において深く折り込む。ただこの場合円錐の母線が片側短くなるのでフィルターの縁に低い方向ができ、粉の収容量が制限される。大きなフィルターを使うか、角度を変えて複数枚重ねるなどの対応をとる。
ステンレスワイヤーの枠部材や台座は、かしめ等で製作しても、溶接してもよい。適切な箇所で分割構造にして曲げ加工や組み立ての難易度を下げれば、生産性を向上できる。強度・耐熱・食品衛生上問題ない他の材質でも良い。枠部材を分割構成として2次交差以上の交差部分を前記した保持力強化に適した材質・形状にする方法もある。構成の単純化と生産性の両立が可能である。一体成形できる材質にすれば大量生産もできる。
台座の構造は、ガイド部の構成等の条件から最適な形をとる。収納サイズにこだわらなければ、複数ピース構成でなく一体型でも構わない。他の素材を使用して、安定性やデザイン性を追求する方策もある。たたんだガイド部の収納ケースを台座とするなど、別の次元で使い勝手を向上できる可能性もある。
衛生面や使用・洗浄後の排水性を考慮して保持部材にステンレス細ワイヤーを採用したが、強度・耐熱・食品衛生上問題ない部材であれば使用できる。板状または網状の部材を使用してフィルター保持の安定度を増すこともできる。
断面形状の保持を工夫すれば、台座のない構成も可能である。枠部材の径以下の受け容器にはそのまま置くことができる。受け容器内への沈みは大きくなるが、安定して自由な姿勢にセットできる。岩場など受け容器の水平を保つことが困難な場合など状況によっては却って好適である。ドリッパーの転倒防止や水平支持を補助する突起や取手などを設けても良い。キッチンや店舗での使用を考慮すれば、本品単体では台座や断面形状の保持手段も最小限もしくは省略し、市販のコーヒードリッパーなどに装着して抽出度合いをカスタマイズする器具としての展開にも可能性を見出すことができる。 As described above, the second embodiment in which only the self-shape holding force of the guide portion is used has been described. A simpler structure and operability than in the first embodiment can be obtained. The guide fixing part to the pedestal is illustrated as an example different from the first embodiment. It may be attached at theprimary intersection 131. The comfort of hand-held drip and how it sinks into the receiving container will change. Actually, it is selected appropriately based on the user's drip method and compatibility with other instruments used.
The number of frame members may be three or more. The greater the number, the closer the cross section holding the filter is to a circle. However, an even number configuration is desirable for folding similar to FIGS. Although the definition of the regular polygon is somewhat complicated, the structure for maintaining the shape can be simplified by optimally selecting the side that determines the length and the vertex that determines the maximum outer shape. As with the previous example, a one-touch folding structure is also possible.
The opening angle of the cone can be 60 degrees or more. In this case, the filter is folded deeply on the apex side of FIG. In this case, however, the conical busbar becomes shorter on one side, so that the edge of the filter can be lowered, and the amount of powder contained is limited. Take measures such as using a large filter or stacking multiple sheets at different angles.
The frame member and pedestal of the stainless wire may be manufactured by caulking or the like, or may be welded. Productivity can be improved if the difficulty of bending and assembly is reduced by dividing the structure at appropriate locations. Other materials that are not problematic in terms of strength, heat resistance, and food hygiene may be used. There is also a method in which the frame member is divided into a material / shape suitable for strengthening the holding force as described above at the intersecting portion of the secondary intersection or higher. It is possible to achieve both simplification of configuration and productivity. Mass production is possible by using a material that can be integrally molded.
The structure of the pedestal takes an optimum shape from the conditions such as the configuration of the guide portion. As long as the storage size is not concerned, it may be an integral type instead of a multi-piece configuration. There is also a strategy to pursue stability and design using other materials. There is a possibility that usability can be improved in another dimension, such as using a storage case for the folded guide as a base.
In consideration of hygiene and drainage after use / cleaning, stainless steel wires are used for the holding member, but any member that does not have any problems in strength, heat resistance, and food hygiene can be used. A plate-like or net-like member can be used to increase the stability of filter holding.
If the cross-sectional shape is maintained, a configuration without a pedestal is possible. It can be left as it is in a receiving container having a diameter equal to or smaller than the diameter of the frame member. Although the sinking into the receiving container becomes large, it can be set in a stable and free posture. Depending on the situation, such as when it is difficult to keep the receiving container level such as a rocky place, it is preferable. You may provide the protrusion, handle, etc. which assist dripping fall prevention and horizontal support. Considering use in kitchens and stores, this product alone can be used as a tool that can be mounted on a commercially available coffee dripper and the degree of extraction can be customized by minimizing or omitting pedestal and cross-section holding means.
