Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a coffee extractor for extracting a coffee extract from a coffee powder ground coffee grounds cartridge.

[0002]

[Prior art]

 Conventionally, as a device relating to a coffee extractor, a "simple drip coffee maker" of Japanese Utility Model Publication No. 59-19034 has been disclosed.

The "simple drip coffee brewing machine" of Japanese Utility Model Laid-Open No. 59-19034 has a projecting portion formed on the bottom side of the main body of the container, and a window for extracting coffee is formed on the bottom of the projecting portion. , A coffee pack containing coffee powder with a filter paper is fitted in the protruding part, and when hot water is poured into the coffee pack from above, the coffee extract is extracted from the window of the protruding part.

[0004]

[Problems to be solved by the device]

 However, in the "Simple drip coffee brewer" of No. 59-19034, the container body is separate from the coffee pack, so the container body is not wasted. However, when pouring hot water, the coffee pack floats up. To prevent this, the coffee pack is fitted inside the protrusion, so removing the coffee pack after brewing is troublesome. Also, when a large amount of hot water is poured at one time, the top surface of the coffee pack is covered with hot water so that there is no way for air to escape, making it difficult for coffee to be extracted, or from the gap between the coffee pack and the container body. There is a problem that the extraction concentration of the coffee extract extracted from unextracted hot water flows out.

It is an object of the present invention to provide a low-cost coffee extractor which has a high extraction concentration of coffee extract, makes it easy to attach and detach a coffee pack, and does not waste the container body.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, a coffee extractor according to the present invention stores a cartridge in which ground coffee ground coffee powder is enclosed, and pours hot water into this cartridge to extract coffee liquid. It is a container that consists of a cylindrical container main body with a coffee extraction opening at the bottom and a lid attached to the upper opening of this container main body, which supports the cartridge stably inside the container main body. And a cylindrical rib that presses the filter paper on the upper part of the cartridge so as to be located at a position lower than the height of the peripheral portion of the lid body is formed on the surface of the lid body facing the inside of the container body. The feature is that a hot water inlet is opened in the area surrounded by the ribs.

[0007]

[Action]

 According to the coffee extractor of the present invention, when the lid is attached to the upper opening of the container body, the tubular rib presses the filter paper of the cartridge to the bottom side of the container body, and the filter paper portion surrounded by the tubular rib is attached. Is located at a position lower than the peripheral edge of the cartridge, and the portion surrounded by the tubular rib is partitioned from the peripheral edge of the cartridge.

Therefore, when hot water is poured into the tubular rib from the inlet of the lid, the hot water enters the portion located inside the tubular rib, and the air in the coffee powder flows from the peripheral portion of the cartridge into the air. Since the water can penetrate into the coffee powder, the hot water can penetrate into the coffee powder and the coffee extract can be easily extracted. Moreover, since the portion surrounded by the tubular ribs is located at a position lower than the filter paper on the peripheral portion of the cartridge, the water droplets attached to the inside of the upper surface of the cartridge are prevented from spreading to the peripheral portion of the cartridge. Therefore, hot water permeates the ground coffee powder in the cartridge sufficiently to extract the coffee extract having a high extract concentration.

EXAMPLE A coffee extractor according to an example of the present invention will be described below with reference to the drawings.

FIG. 1 shows a sectional structure of a coffee extractor according to a first embodiment, and the coffee extractor 1 is composed of a container body 2 and a lid 3.

The container body 2 has an opening 4 at the top, and has a bottomed cylindrical shape in which a coffee extraction port 6 for extracting the coffee extract is opened at the bottom 5. The periphery of the coffee extraction port 6 of the bottom portion 5 is a tapered surface. The tubular portion of the container body 2 is composed of an upper tubular portion 2a and a lower tubular portion 2b, and the upper tubular portion 2a has a larger diameter than the lower tubular portion 2b. A step portion 7 serving as a support portion is formed at a boundary portion between the lower cylindrical portion 2b and the lower cylindrical portion 2b. The upper flange 9a of the cartridge 8 is mounted on the step portion 7.

The cartridge 8 stores coffee powder 8a obtained by grinding coffee beans into powder, and as shown in FIGS. 2 and 3, a cylindrical frame 9 having an upper diameter larger than that of the lower portion is provided. I have it. Filters 10 and 11 made of, for example, filter paper are stretched at the upper and lower openings of the frame body 9. A plurality of elongated supporting ribs 12 for supporting the filter 11 are formed in the lower opening of the frame body 9. As the supporting ribs, actually, as shown in the drawing, a half-moon shaped protrusion 12a is provided to make contact with the bottom surface of the lower tubular portion, and even if the supporting ribs are bent by the heat of the pouring hot water, the flow of the extraction liquid will The road is not blocked. Lower portions of the supporting ribs 12 project toward the bottom portion 5 side, and the supporting ribs 12 guide the extraction liquid extracted by the filter 11 to promote the dropping of the liquid. A flange 9a protruding laterally of the frame body 9 is formed on the upper end of the frame body 9, and an upper filter 10 is stretched on the flange 9a. When the flange 9a is locked to the step portion 7, the upper portion of the frame body 9 faces the inner wall of the lower tubular portion 2b with a slight gap.

A handle 13 is projectingly provided on the outer peripheral surface of the upper tubular portion 2a. The lid 3 is fitted into the opening of the upper tubular portion 2a. A concave portion 14 is formed in the central portion of the lid body 3, and the central portion of the concave portion 14 slightly bulges upward so as to disperse the poured hot water in all directions. Openings 16 are formed on the four sides of the support wall 15 of the recess 14 so as to uniformly fill the cartridge 8 with hot water. A cylindrical rib 17 having a cylindrical shape is provided so as to project around the periphery of the recess 14. When the cartridge 7 is supported by the step 7, the tubular rib 17 slightly projects further toward the bottom 5 than the step 7, and the upper filter 10 of the cartridge 8 can be bent toward the lower filter 11. It has a height that comes out.

Next, a state in which hot water is poured into the coffee extractor 1 according to the first embodiment to extract the coffee extract will be described.

When the flange 9 a of the cartridge 8 is mounted on the step portion 7 and the lid 3 is fitted to the upper end portion of the upper tubular portion 2 a, the lower end portion of the tubular rib 17 is positioned below the step portion 7. As a result, the upper filter 10 of the cartridge 8 bends slightly below the height of the flange 9a, and an inclined surface inclined toward the cylindrical rib 17 side is formed at the peripheral edge of the upper filter 10.

When hot water is poured into the recess 14 on the coffee cup 1 (not shown), the coffee extractor 1 is separated from the opening 16 of the support wall 15 of the recess 14 by the cylindrical rib 17 and the upper filter 10. Hot water temporarily accumulates in the space. The hot water that has passed through the upper filter 10 enters the cartridge 8 and enters the coffee powder 8a. The air contained in the coffee powder 8a, the air contained in the cartridge 8 and the carbon dioxide gas generated from the coffee powder 8a pass through the upper filter 10 and the space between the cylindrical rib 17 and the upper cylindrical portion 2a. Move to. As a result, hot water easily enters between the particles of the coffee powder 8a, and the extraction of the coffee extract is promoted. When the hot water enters the cartridge 8, water droplets 18 are formed on the inner wall surface of the cartridge of the upper filter 10, but since the inclined surface is formed on the peripheral portion of the upper filter 10, the water droplet 18 is formed by the step portion 7. Leakage is prevented. Therefore, it is possible to extract a coffee extract having a high extraction concentration. The hot water that has penetrated between the particles of the coffee powder 8a extracts the coffee component from the coffee powder particles and falls from the lower filter 11. The coffee extract that has dropped from the lower filter 11 is received by the tapered surface of the bottom portion 5 and drops from the coffee extraction port 6 into the coffee cup. Further, the coffee extract adhering to the support ribs 12 is guided and collected at the lower end portions of the support ribs 12 and falls to the bottom portion 5.

Next, the coffee extractor 20 of the second embodiment will be described.

FIG. 4 shows a cross section of the coffee extractor 20 according to the second embodiment. The coffee extractor 20 accommodates a large cartridge 8 and is provided on the upper part of the container body 21. The part 22 is formed. The lid body 23 fitted into the upper end opening of the container body 21 is provided with a recess 24 as in the lid body 3 of the first embodiment, and an opening 26 through which hot water is passed through a supporting wall 25 of the recess 24. Has been formed. A cylindrical rib 27 is provided so as to project around the recess 24. The tip of the tubular rib 27 projects slightly below the step 22, and when the lid 23 is fitted onto the upper part of the container body 21, the upper filter 10 of the cartridge 8 bends downward and the peripheral edge of the upper filter 10 is bent. An inclined surface is formed on the portion. The other configurations are similar to those of the first embodiment, and thus the description of the first embodiment is cited. In addition, 28 is a handle protruding from the upper end of the container body 21.

According to the coffee extractor 20 of the second embodiment, when hot water is poured into the recess 24, the hot water enters the space partitioned by the cylindrical rib 27 and the upper filter 10 through the opening 26. Since the tubular rib 27 has a large diameter and the upper filter 10 has a large diameter, the hot water in the tubular rib 27 enters the cartridge 8 without being accumulated above the upper filter 10. The hot water that has entered the cartridge 8 permeates between the particles of the coffee powder 8a to extract the coffee component, drops from the lower filter 11 through the coffee extraction port 29 of the bottom 28 of the container body 21, and mounts the coffee extractor 20. Accumulates on a coffee server.
