Description

  The present invention relates to a dripper for extracting coffee liquid by pouring hot water into coffee powder put in a filtration filter.

  2. Description of the Related Art Conventionally, a cup-shaped dripper having a base for placing on a container and having a hole in the bottom is known as an apparatus for easily extracting coffee liquid from ground coffee beans. When this dripper is placed in a container, the filter is accommodated, and coffee powder is poured into the filter and poured with hot water, the coffee liquid is dripped from the hole of the dripper and extracted into the container.

  However, since the conventional dripper is made of resin, metal, ceramics, and the like and has a wall with which the filter is in contact, it has the following problems. In other words, it is inconvenient to carry and is not suitable for making coffee casually outdoors. In addition, a part of the poured hot water oozes out from the filter without sufficiently contacting the coffee beans, flows down to the bottom along the wall of the dripper, and forms a path that drops into the container from the bottom hole Is done. Furthermore, there is a problem that the filter does not deform due to the wall of the dripper and the swelling of the coffee powder is prevented, or the heat of hot water escapes through the wall of the dripper.

  As a portable dripper, Patent Document 1 discloses a coffee funnel in which an elastic powder receiver having an appropriate number of folding lines formed on the side surface is formed, and the powder receiver can be stored and transported in a folded state. The ingredients are listed. Further, Patent Document 2 describes a dripper that is made of an expandable and contractible spiral wire wound around a small diameter downward, and that can be folded and stored and carried. In these drippers, the powder receiver and the wire are not deformed during the extraction of the coffee liquid, so that the swelling of the coffee powder is prevented.

  Patent Document 3 describes a coffee dripper that can adjust an opening angle of a portion that holds a filter by combining three or more frame members. Although the opening angle of this dripper can be adjusted, the frame member of the filter is not deformed during the extraction of the coffee liquid, and the side surface of the filter is held by the wire member and the chain, so that the swelling of the coffee powder is prevented.

  In Patent Document 4, the upper part of the filter paper is sandwiched between a filter paper receiving ring provided with a handle and a filter paper holding ring, and can be easily discarded. A coffee dripper is described that is capable of extracting a strong coffee liquor. Although this dripper can be used like a flannel dripper, since the upper end of the filter paper is fixed, the swelling is not sufficient. In addition, since the filter paper is less likely to expand and contract as compared with flannel, it is difficult to freely deform, and free swell of coffee powder is prevented.

  The present invention has been made in view of such conventional problems, and the filtration filter can be deformed during the extraction of the coffee liquid, so that it is convenient for a mobile phone that can extract delicious and rich coffee liquid. It is an object to provide a simple dripper.

As a means for solving the above problems, the present invention provides:
A dripper comprising: a stretchable main body that can be deformed in a mesh shape so as to hold a filtration filter; and a support member that supports a peripheral edge of the main body.

  The dripper of the present invention supports the peripheral edge of the main body by a support member and installs the support member on the container. A filter is placed on the main body and pushed in to deform the main body into a mesh shape. Add coffee powder to the filter and pour hot water to extract the coffee liquid into the container. Since the main body of the dripper has a mesh shape having elasticity, the dripper extends downward in the radial direction due to the weight of the coffee powder and hot water. Along with this, the filter is deformed so as to swell, so that hot water can be evenly distributed over the coffee powder and the coffee powder can be sufficiently expanded.

  The main body has a plurality of cut portions formed in the circumferential direction and spaced in the radial direction, and non-cut portions at both ends of the cut portion are opposed to the middle of the cut portions adjacent in the radial direction. It is preferable.

  It is preferable that the width of the non-cut portion located on the radially outer side is larger than the width of the non-cut portion located on the radially inner side.

  Preferably, the support member includes a first support member and a second support member that sandwich the peripheral edge of the main body.

  It is preferable to further include a filter pressing member disposed inside the filtration filter held by the main body.

  According to this invention, since it has a net-like main body having elasticity, the main body extends downward and expands in the radial direction due to the weight of coffee powder and hot water. Along with this, the filtration filter is deformed so as to swell, so that the coffee powder swells sufficiently and a delicious coffee liquid with a delicious taste and richness can be extracted.

  Next, embodiments of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 shows a dripper 1 according to the present invention, a known filter 2 and a filter holding member 3. As shown in FIG. 2, the dripper 1 is composed of a main body 4 and a support member 5 (first support member 5a and second support member 5b).

  The main body 4 of the dripper 1 is a circular sheet made of a stretchable material such as silicon rubber having a diameter of about 110 mm and a thickness of 1 mm. As a material for the main body 4, polypropylene, polyethylene, polyvinylidene chloride, polytetrafluoroethylene, and the like can be used in addition to silicon rubber. The main body 4 is provided with a plurality of cut portions 6 as described below, and can be deformed into a mesh shape so as to hold the filtration filter 2.

  As shown in FIG. 3, the arcuate four cut portions 6 are formed in the main body 4 in the circumferential direction via the non-cut portions 7, and are formed in eight locations at intervals in the radial direction. Yes. The cut portion 6 is arranged on a concentric circle. The main body 4 includes a peripheral edge 8 outside the notch 6 located on the outermost side in the radial direction, and a mesh-like part 9 inside the notch 6. Eight engaging holes 10 are formed in the circumferential portion 8 of the main body 4 at equal intervals in the circumferential direction. At the center of the mesh portion 9 of the main body 4, an opening portion 11 through which the coffee liquid 23 dripping from the filtration filter 2 passes is formed.

  The non-cut portions 7 at both ends of the cut portion 6 of the main body 4 face the middle of the cut portions 6 that are adjacent in the radial direction. The odd-numbered non-notched portions 7 from the outer periphery are aligned in the radial direction, and the even-numbered non-notched portions 7 from the outer periphery are aligned in the radial direction with a 45 ° circumferential shift with respect to the odd-numbered non-notched portions 7. doing. Of the aligned non-cut portions 7, the width of the non-cut portion 7 located on the radially outer side is formed larger than the width of the non-cut portion 7 located on the radially inner side. This is because the strength of the non-cut portion 7 on the radially outer side where the weight of the coffee powder 22 and hot water contained in the filtration filter 2 acts the largest is greater than that of the non-cut portion 7 on the radially inner side. Small holes 12 are formed at both ends of each cut portion 6 to prevent stress from concentrating at both ends of the cut portion 6.

  Returning to FIG. 2, the support member 5 of the dripper 1 is made of a synthetic resin such as polycarbonate, and as shown in FIG. 2, the first support member 5 a positioned below the main body 4 and positioned above the main body 4. It consists of the second support member 5b.

  The first support member 5 a includes an annular part 13 on which the peripheral edge 8 of the main body 4 is placed, and a handle 14 that protrudes outward from a part of the annular part 13. On the upper surface of the annular portion 13, eight engagement protrusions 15 that are engaged with the engagement holes 10 of the main body 4 are formed at equal intervals in the circumferential direction. Further, four magnets 16 are embedded in the upper surface of the annular portion 13 at equal intervals in the circumferential direction.

  The second support member 5 b has the same outer shape as the first support member 5 a, and an annular portion 17 placed on the peripheral edge portion 8 of the main body 4, and a handle 18 that protrudes outward from a part of the annular portion 17. And have. A magnet 19 having a polarity that is attracted to the magnet 16 is embedded in a lower surface of the annular portion 17 at a position facing the magnet 16 of the first support member 5a. Instead of the magnet 19, a metal having magnetism may be embedded.

  Returning to FIG. 1, as long as the filtration filter 2 is made of paper and can be expanded into a conical shape or a trapezoidal shape, a commercially available filter such as Carita Wave or Hario V60 can be used. Although FIG. 1 shows Carita Wave having sidewalls formed in a corrugated shape, the present invention is not limited to this.

  The filter pressing member 3 is annular, and as shown in FIG. 4, an annular projection 20 is formed on the lower surface. The filter holding member 3 is placed on the filtration filter 2 so that the annular protrusion 20 is located inside the upper edge of the filtration filter 2, and the filter filter 2 is greatly reduced by the weight of the coffee powder 22 and hot water. To prevent. Further, as described in detail later, by using a filter holding member having a different diameter, the diameter of the upper edge of the filtration filter 2 can be changed, and the thickness of the layer of the coffee powder 22 can also be changed. This makes it possible to control the extracted components.

  Next, the usage method of the dripper 1 of this embodiment is demonstrated. As shown in FIG. 5, the dripper 1 is placed on the main body 4 on the annular portion 13 of the first support member 5a, and the engagement hole 10 of the peripheral edge portion 8 of the main body 4 and the annular portion 13 of the first support member 5a. After engaging the engagement protrusion 15, the annular portion 17 of the second support member 5b is placed on the main body 4, and the magnet 19 of the second support member 5b and the magnet 16 of the first support member 5a are attracted, The handle 16 of the first support member and the handle 18 of the second support member are overlapped. In this manner, the peripheral edge 8 of the main body 4 is sandwiched and supported by the first support member 5a and the second support member 5b.

  After assembling the dripper 1 in this manner, the annular portions 13 and 17 of the support member 5 of the dripper 1 are installed on the opening edge of the container 21 as shown in FIG. Subsequently, the filtration filter 2 is placed on the main body 4 and pushed downward to deform the main body 4 into a mesh shape as shown in FIG. When an appropriate amount of ground coffee powder 22 is put into the filter 2 and hot water is poured, the coffee liquid 23 that has passed through the filter 2 is extracted into the container 21 through the opening 11 as shown in FIG. .

  Since the main body 4 of the dripper 1 has elasticity and a plurality of cut portions 6 are formed, as shown in FIG. 7, the dripper 1 extends downward and expands in the radial direction due to the weight of the coffee powder 22 and hot water. . Along with this, the filtration filter 2 swells and deforms like a nell dripper, so that the hot water can be evenly distributed over the coffee powder 22 to sufficiently inflate the coffee powder 22, and the coffee liquid 23 having umami and richness. Can be extracted.

  The reason why it is possible to extract the savory and rich coffee liquid 23 is not clear, but by removing the fixed wall as much as possible, the coffee powder 22 swells more appropriately and evenly than before, and the permeated hot water becomes more free. It is thought to spread. Further, the interval between the particles of the coffee powder 22 spreads uniformly, the permeated hot water spreads over the porous walls of the porous particles of the coffee powder 22, and it becomes easier to extract the low-solubility component. It is considered that the sugar-derived viscous components are appropriately extracted together with a wide variety of polyphenols including the above, resulting in a more complex and rich taste.

  If the filter holding member 3 having a small diameter is used, the upper edge of the filtration filter 2 becomes narrow as the main body 4 is deformed and moved downward due to the weight of the poured hot water, and the height of the coffee powder 22 layer increases. Since the thickness in the vertical direction increases, the time during which the coffee powder 22 and hot water are in contact with each other becomes longer, and the extracted components can be adjusted.

  Moreover, since the main body 4 of the dripper 1 has a mesh shape, a path through which the hot water or coffee liquid 23 that has leached from the filtration filter 2 flows along the surface of the main body 4 is not formed. The coffee liquid 23 and hot water that have leached without the portion sufficiently contacting the coffee powder 22 do not fall into the container 21.

  Furthermore, since the main body 4 of the dripper 1 has a mesh shape, the heat held in the coffee powder 22 by the hot water in the filtration filter 2 does not escape. For this reason, the temperature of warm coffee liquid 23 does not fall, and warm coffee can be drunk. In addition, the cylindrical member that covers the outside of the main body 4 so as not to contact the mesh-shaped main body 4 between the support member 5 and the opening edge of the container 21 or the movement of the main body 4 deformed into a mesh shape is not hindered. However, by interposing the mortar-shaped coffee server along the outer shape of the main body 4, the heat insulation effect by the air insulation is further enhanced, and the fragrance component is difficult to escape.

  Further, the main body 4 of the dripper 1 is deformed into a mesh shape as shown in FIG. 1 depending on its own weight, the weight of the filtration filter 2, the coffee powder 22 and the hot water, but when it is not used, as shown in FIG. Because it becomes convenient, it is convenient to carry and you can easily make coffee outdoors.

  The present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the invention described in the claims of the utility model registration. For example, the first support member 5a and the second support member 5b of the support member 5 may be screwed with screws or the like, fixed with a clip, a part of the outer periphery may be joined with a hinge, or a fitting structure may be adopted. . Further, the first support member 5a and the second support member 5b do not have the same outer shape, and the handle 14 may be provided only on the first support member 5a. The number and arrangement of the cut portions 6 of the main body 4 of the dripper 1 can be changed as appropriate.
