Description

  The present invention relates to a dripper to which a filter is attached, in which an opening is formed on a side surface of the dripper.

  As a funnel-shaped one used as, for example, a coffee dripper, there is a conventional one shown in FIG. The coffee dripper 11 is engaged with and held by a funnel portion 12 that functions as a filter holding portion, a handle 14 attached to the outer peripheral portion thereof, and a frame of an extraction liquid container 31 that receives and holds coffee after extraction. And a ridge 13 for the purpose. Further, a plurality of ribs 16 are arranged on the inner peripheral surface of the funnel portion 12 in a spiral shape in which the intervals are increased from below to above.

The ribs 16 are configured to rise so as to gradually increase in the downward direction, and when the paper filter 21 is attached, the ribs 16 are uniformly aerated without being in close contact with the inner peripheral surface of the funnel portion 12. Steaming is performed uniformly and smoothly so as not to impair the flavor of the extracted coffee. As shown in FIG. 6, an additional rib 17 is formed between the ribs 16 above the inner peripheral surface of the funnel portion 12, and the inner periphery of the funnel portion 12 of the paper filter 21 due to an increase in the gap between the ribs 16. It is intended to prevent adhesion to the surface.
Utility Model Registration No. 3116219

  The above-mentioned coffee dripper 11 has a conical shape in which the diameter of the funnel portion 12 is narrowed downward, and the paper filter 21 used to add delicious coffee also has the same conical shape. It was necessary to use something. However, some of the commercially available paper filters 21 are fan-shaped (trapezoidal). When this fan-shaped paper filter 21 is used, it must be bent into a conical shape and set on a dripper. Therefore, when the paper filter 21 is bent and used in this manner, the bent portion comes into close contact with the inner periphery of the funnel portion 12, and it is difficult to add coffee that does not impair the flavor as described above. It was.

  Further, when the filter 21 is conical, the hot water to be poured is shaped to easily spread over the entire coffee powder, whereas the poured hot water and the extracted coffee are directed toward the tip 21A of the filter 21. Since it flows, the extraction of coffee from the coffee powder in the vicinity of the tip 21A of the filter 21 is finished quickly, resulting in a spilled state. In this way, when a part that is in an extended state is formed, it becomes impossible to efficiently extract coffee from the coffee powder in the filter by improving the hot water poured into this part, and delicious coffee It was difficult to put in.

  Accordingly, an object of the present invention is to provide a dripper that can extract coffee without impairing the flavor of coffee regardless of the shape of the filter.

  In order to achieve the above object, the present invention corresponding to claim 1 is a dripper in which a plurality of ribs are formed in a filter holding portion for holding a filter, and the gap between the ribs constituting the filter holding portion. The shape of the surface located at is a curved surface, and at least a pair of the surfaces facing each other is formed with a notch.

  In this way, the filter holding surface is composed of a plurality of curved surfaces divided by a plurality of ribs, and at least a pair of the opposed surfaces are formed with notches so that a commercially available fan-shaped (trapezoidal) filter can be obtained. Even if the filter is not similar to the filter holding part or the filter is larger than the filter holding part, the filter is not bent and set out of the notch, so that the inner surface of the dripper (filter holding Part) and the filter. Therefore, when the filter is mounted, the degree of close contact of the filter with the filter holding portion can be reduced. Therefore, as described above, even when a fan-shaped (trapezoidal) filter is used, it is possible to uniformly perform ventilation between the filter holding portion and the filter, and steam the coffee powder uniformly and smoothly. The flavor of the extracted coffee is not impaired.

  In addition, the extraction liquid can also be discharged from such a notch due to the formation of a notch in at least a pair of opposite curved surfaces of the curved surfaces constituting the filter holding portion. Therefore, it cannot be discharged from the dripping hole for the extracted droplet of the dripper and collected in the space between the dripper and the filter. As a result, the extraction of coffee from the coffee powder near the tip of the filter is finished quickly, and it is possible to suppress the occurrence of the brewing state, to perform the coffee extraction more efficiently, and to improve the coffee flavor Can do.

  According to a second aspect of the present invention, there is provided a cone-shaped dripper in which an opening is formed in an upper portion, a hole for extracting droplets is formed in a lower portion, and a diameter in a cross-sectional direction is narrowed from the upper portion to the lower portion. The dripper has a shape in which a plurality of concave surfaces are arranged in a radial pattern so that the side surface of the dripper expands upward from the hole for extracting droplets, and an opening is formed in at least a pair of confronting concave surfaces. And

  In this way, the side surface of the dripper is composed of a plurality of concave surfaces formed so as to expand radially upward from the hole for lowering the extraction droplet, and at least a pair of opposed concave surfaces are formed with openings. Even if a commercially available fan-shaped (trapezoidal) filter is not similar to the filter holder or the filter is larger than the filter holder, the filter is not bent and set out of the notch. As a result, a gap is formed between the inner surface of the dripper (filter holding portion) and the filter even during coffee extraction. Therefore, when the filter is mounted, the degree of close contact of the filter with the filter holding portion can be reduced. Therefore, as described above, even when a fan-shaped (trapezoidal) filter is used, it is possible to uniformly perform ventilation between the filter holding portion and the filter, and steam the coffee powder uniformly and smoothly. The flavor of the extracted coffee is not impaired.

  Note that the “conical shape” is a curved surface (or one of several planes) formed by connecting a point that goes around the circumference of a planar closed curve (or broken line) and one point outside the plane. This includes not only cones and pyramids, which are part of the space surrounded by (part), but also those surrounded by a curved surface created by a straight line connecting these lines with a point outside the plane as a line.

  Further, since the opening is formed in at least a pair of confronting concave surfaces, the extraction liquid can be discharged from such an opening, and the dripper cannot be completely discharged from the extraction droplet lowering hole of the dripper. No longer accumulate in the space between the filter and the filter. Therefore, the extraction of coffee from the coffee powder near the tip of the filter can be completed quickly, and it can be prevented that it is in a brewing state, the coffee can be extracted more efficiently, and the coffee flavor can be improved. .

  Furthermore, according to this aspect, even when the filter is large, the above-described effects are obtained when the filter is protruded without being bent and when the coffee powder is put into the protruding portion and set in the dripper. You can get a savory coffee.

  The invention corresponding to claim 3 is the dripper of the invention corresponding to claim 1 or 2, in which a ridge for mounting on the extraction liquid container is formed on the outer surface of the filter holding surface. Thus, drippers can be placed on various containers by forming the ridges.

  As described above, according to the present invention, it is possible to provide a dripper that can extract coffee without impairing the flavor of coffee regardless of the shape of the filter.

  Embodiments of the present invention will be described below with reference to the drawings.

(First embodiment)
First, an example of the dripper of the present invention will be described. FIG. 1 is a plan view when the dripper in this example is viewed from above, FIG. 2 is a side view when the dripper shown in FIG. 1 is viewed from the side, and FIG. 3 is shown in FIG. It is a top view at the time of seeing a dripper from the downward direction. The dripper 1 shown in FIGS. 1 to 3 includes a filter holding portion 2, a flange portion 3 formed on the outer peripheral surface of the filter holding portion 2, and a handle 4 formed on the flange portion 3. In this example, the dripper 1 shown in the figure is integrally formed with all the members such as the filter holding portion 2 using polypropylene resin or the like. However, in the present invention, such integral molding is not an essential component.

  The filter holding part 2 has a funnel shape and a hole 5 for extracting droplets is formed in the lowermost part. The inner surface of the filter holding part 2 has a plurality of rib-like filter contact parts 6 and a space between the filter contact parts 6. It is formed by a curved surface 7 that is convex outward, and an opening 8 is formed on the two opposite surfaces of the curved surface 7. Since the opening 8 is formed from the vicinity of the upper end of the curved surface 7 to the vicinity of the hole 5, the paper filter can be easily set.

  The flange portion 3 is formed in a donut shape so as to surround the outer peripheral surface of the filter holding portion 2, and an opening hole 9 is formed at a position corresponding to the opening portion 8.

  The handle 4 was formed so as to protrude outward from the collar 3 to a position including one of the openings 8.

  A fan-shaped paper filter (for 2 to 4 cups) marketed in the dripper 1 is set so as to protrude into the opening 8, 30 g of coffee powder is added to about 10 g per person, and hot water is poured to extract coffee. At this time, the paper filter swells to the outside due to the poured hot water, but the side surface of the paper filter is held by the filter contact portion 6 and is less likely to contact the curved surface 7. Thus, by making the paper filter into line contact instead of surface contact, the ventilation to the paper filter becomes uniform, and the coffee flavor is not impaired.

  Further, since most of the side surface of the paper filter is not in contact with the dripper, the coffee oozes out from the side surface, slowly flows down the outer surface of the paper filter, and can be dripped into the extraction liquid container. Furthermore, a part can pass through the opening part 8 and the opening hole 9, and can be dripped in the container for extraction liquids. Thus, by slowly extracting coffee, it is possible to draw out a taste, aroma, and richness that are close to nel drip (cloth drip).

  Further, since the paper filter is not bent and protruded and set in the dripper, a part of the paper filter tip is also protruded. That is, when the coffee liquid extracted from the poured hot water reaches the front end of the paper filter, the extracted liquid directly from not only the hole 5 of the dripper 1 but also from the front end of the paper filter through the opening 8 and the opening hole 9. It can be dripped into a container for use.

  Therefore, the extracted coffee liquid that falls on the tip of the paper filter can be dripped from a wide range and does not collect between the dripper and the paper filter, so that the time required for the coffee powder to come out at the tip of the paper filter is extended. Therefore, the coffee liquid can be efficiently extracted from the coffee powder put into the paper filter.

(Second Embodiment)
Next, another example of the dripper of the present invention will be described. FIG. 4 is a plan view of the dripper in this example as viewed from above. In addition, since the side shape of the dripper in this example is similar to FIG. 2, description is abbreviate | omitted in this example. Note that the same reference numerals are used for similar and identical components.

  In this example, as shown in FIG. 4, four openings 8 are formed on the curved surface 7 between the filter contact portions 6. The filter holding portion 2 of the dripper 1 forms eight filter contact portions 6 and opens openings 8 every other curved surface 7 (that is, opens openings 8 on two opposing surfaces). In addition, the line connecting the opening portions 8 facing each other is formed so as to intersect at approximately 90 degrees. Also in this example, the opening 8 is formed so as to extend from the vicinity of the upper end of the curved surface 7 to the vicinity of the hole 5.

  Like the first embodiment, the flange 3 is formed in a donut shape surrounding the outer peripheral surface of the filter holding portion 2, and an opening 9 is formed in a corresponding portion of the opening 8. Similarly to the above embodiment, the handle 4 is formed integrally with the flange 3 and has a shape extending outwardly so as to include one of the facing openings 8.

  A commercially available conical paper filter (for 2 to 4 cups) is set in the dripper 1, but when setting, the paper filter is folded in half, and the fold is broken into a mountain fold. Set so that it protrudes from part 8. Then, coffee powder is added and hot water is poured to extract coffee.

  At this time, as in the first embodiment, the paper filter swells outward, but since there are four openings 8, the possibility that the side surface of the paper filter is in contact with the curved surface 7 is reduced as compared with the first embodiment. be able to. Therefore, since the extracted coffee can be slowly flowed downward in this example, it is possible to draw out the taste, aroma, and richness close to nel drip.

  Moreover, since the opening 8 is opened to the vicinity of the hole, the coffee liquid extracted from the poured hot water is not easily collected between the dripper 1 and the paper filter, so that the coffee powder at the front end of the paper filter is discharged. Can be extended. Therefore, since coffee can be efficiently extracted from the coffee powder, rich and delicious coffee can be added.

  In this embodiment, a conical paper filter is used, but the same effect can be obtained by using a fan-shaped paper filter. Moreover, not only a paper filter but the filter formed with the nonwoven fabric can also be used.

  Further, in order to place the dripper 1 on the extraction liquid container, the doughnut-shaped eaves portion 3 is formed. By extending the handle 4 outward from the curved surface 7 where the entire opening portion 8 is formed, You may make it mount the dripper 1 in the container for extract liquids using the handle 4. FIG.

  FIG. 5 is a modification of the example shown in FIG. 4. In the filter holding part 2, twelve filter contact parts 6 are formed, and an opening 8 is opened every two curved surfaces 7 (that is, two sets of Unlike the example shown in FIG. 4, the same applies to the other constituent elements in that the opening 8 is opened on two opposing surfaces.

  The present invention has been described in detail based on the above specific examples. However, the present invention is not limited to the above specific examples, and various modifications and changes can be made without departing from the scope of the present invention.

  By adding the function of holding the filter to the collar 3 formed on the dripper 1, the extractables (tea leaves and green tea leaves) in the filter can be stored in the extract container even if the filter is immersed in the extract container. An extract (black tea or green tea) can be obtained without falling.

It is a top view at the time of seeing an example of the dripper of the present invention from the upper part. It is a side view at the time of seeing the dripper shown in FIG. 1 from a horizontal direction. It is a top view at the time of seeing the dripper shown in FIG. 1 from the downward direction. It is a top view at the time of seeing the other example of the dripper of this invention from upper direction. It is a top view at the time of seeing the other example of the dripper of this invention from upper direction. It is a sectional side view which shows the structure of the conventional dripper roughly.
