portable coffee dripper
[0001] The present invention relates to a portable coffee dripper, and more particularly, to a portable coffee dripper that is foldable for convenient portability and can secure sufficient extraction time.
[0002] Generally, a coffee dripper is a tool that can simply extract coffee concentrate by placing it on a cup. However, conventional coffee drippers are made of hard materials such as plastic and glass, which makes them difficult to carry.
[0003] To solve these problems, a disposable coffee dripper made of paper material and easy to carry has recently appeared, and is proposed in Republic of Korea Patent No. 10-0255123 (hereinafter referred to as “cited invention”).
[0004] The cited invention has a frame (16) that is in the shape of a square tube and can be folded to reduce the volume, but when water is poured into a filter paper bag that is supported by the frame (16) and contains coffee powder inside, the coffee liquid is not extracted by the water being guided in one direction as it passes through the coffee powder, but rather, the coffee liquid is extracted sporadically as soon as the water is poured, so there is a problem in that the extracted coffee liquid cannot have sufficient flavor.
[0005] The present invention is intended to solve the above-mentioned problems and provides a portable coffee dripper that is foldable for convenient portability and can secure sufficient extraction time to extract coffee liquid with a rich taste and aroma.
[0006] In order to achieve the above object, the portable coffee dripper of the present invention comprises: a dripper body including two first dripper members that are connected at the bottom and arranged to face each other, and two second dripper members that respectively connect the side ends of the two facing first dripper members, and at least one extraction hole is formed at the bottom; and a mounting wing that is integrally formed with the dripper body and allows the dripper body to be mounted on a cup; wherein the first dripper member has a square shape, and the second dripper member has a triangular shape, and the dripper body is formed such that the cross-sectional area gradually decreases as it goes downward, and the second dripper member and the mounting wing are foldable so as to be adjacent to the first dripper member.
[0007] Additionally, the second dripper member may be folded in half based on a folding line formed in the vertical direction and positioned on the inner side of the two first dripper members.
[0008] In addition, the above-mentioned holding wing may include a first holding wing that is formed to protrude outward from the folding line while being integral with the second dripper member and has a first holding groove formed at the bottom into which the upper end of the cup is fitted, and can be positioned on the inside of the second dripper member when the second dripper member is folded.
[0009] In addition, the first retaining wing may have a right triangle shape with the hypotenuse positioned on the folding line, and a plurality of first retaining grooves may be formed along an edge that slopes upward toward the outside of the first retaining wing.
[0010] In addition, the above-mentioned mounting wing includes a second mounting wing that is formed to protrude outward from the boundary line between the first dripper member and the second dripper member and has a width that becomes narrower as it goes downward, and the second mounting wing may have a second hooking groove formed such that the upper outer end forms a hook shape.
[0011] According to the present invention, the dripper body is formed so that the cross-sectional area gradually decreases as it goes downward, so that when a coffee filter is spread inside the dripper body, coffee powder is placed in the coffee filter, and water is poured, the water passes through the coffee powder for a sufficient amount of time and moves toward the extraction hole, so that a coffee liquid having a rich taste and aroma can be extracted.
[0012] In addition, the second dripper member and the support wing can be folded so as to be adjacent to the first dripper member, so that the fold can have a minimal volume, thereby improving portability.
[0013] And, the dripper body can be placed on cups of various sizes through a plurality of first catch grooves formed on the first catch wing, and a second catch wing is provided together with the first catch wing so that the upper part of the cup can be fitted into the first catch groove and the second catch groove, so that the dripper body can be placed stably and firmly.

[0023] The present invention proposes a portable coffee dripper, which comprises: a dripper body having two first dripper members that are connected and arranged facing each other at the bottom, and two second dripper members that respectively connect the side ends of the two facing first dripper members, and at least one extraction hole formed at the bottom, so as to be conveniently portable by being foldable and capable of extracting coffee liquid with a sufficient extraction time, and capable of extracting coffee liquid with a rich taste and aroma; and a mounting wing that is integrally formed with the dripper body and allows the dripper body to be mounted on a cup; wherein the first dripper member has a square shape and the second dripper member has a triangular shape, and the dripper body is formed such that the cross-sectional area gradually decreases as it goes downward, and the second dripper member and the mounting wing are characterized in that they are foldable to be adjacent to the first dripper member.
[0024] The scope of the present invention is not limited to the embodiments described below, and various modifications may be made by a person having ordinary knowledge in the relevant technical field without departing from the technical spirit of the present invention.
[0025] Hereinafter, the portable coffee dripper of the present invention will be described in detail with reference to the attached drawings 1 to 9.
[0026]
[0027] The portable coffee dripper of the present invention includes a dripper body (100) and a mounting wing (200) that allows the dripper body (100) to be mounted on a cup (10), as shown in FIGS. 1 to 6.
[0028] The dripper body (100) is formed to have a funnel shape as illustrated in FIG. 1 using a foldable material such as paper, so that when in use, a coffee filter can be spread out inside and coffee powder can be accommodated in the spread out coffee filter. At least one extraction hole (130) is formed at the bottom of the dripper body (100) through which the extracted coffee liquid can fall downward as illustrated in FIGS. 2 to 4. At this time, a plurality of extraction holes (130) can be formed at a predetermined interval at the bottom of the dripper body (100), and can be configured to be opened through a cut line so that the extraction speed can be adjusted according to the user's preference.
[0029] The dripper body (100) having at least one extraction hole (130) formed at the bottom as described above includes two first dripper members (110) whose bottoms are connected and arranged facing each other as shown in FIGS. 1 to 4, and two second dripper members (120) which respectively connect the side ends of the two facing first dripper members (110). At this time, the first dripper member (110) has a square shape, and the second dripper member (120) has a triangular shape.
[0030] For example, the first dripper member (110) is formed in a rectangular plate shape having a long length in the vertical direction, and the second dripper member (120) is formed in a triangular plate shape having at least two sides having the same length as the length of the first dripper member (110), so that the first dripper member (110) and the second dripper member (120) can be connected to each other by sides having the same length. In addition, the upper ends of each of the first dripper member (110) and the second dripper member (120) can be formed to form a curved shape having a predetermined curvature. The dripper body (100) formed by the first dripper member (110) and the second dripper member (120) described above has a structure in which the cross-sectional area gradually decreases downward in an unfolded state, as illustrated in FIGS. 1 and 4.
[0031] The dripper body (100) is formed so that the cross-sectional area gradually decreases as it goes downward in this unfolded state. When a coffee filter is unfolded inside, coffee powder is placed inside the coffee filter, and water is poured in, the water passes through the coffee powder for a sufficient amount of time and moves toward the extraction hole (130), so that a coffee liquid with a rich taste and aroma can be extracted.
[0032] And the second dripper member (120) can be folded so as to be adjacent to the first dripper member (110). For example, the second dripper member (120) can be folded in half based on the folding line (121) formed in the vertical direction as illustrated in FIG. 5, and the second dripper member (120) folded in half can be positioned on the inner side of the two first dripper members (110). At this time, the two second dripper members (120) arranged facing each other are folded adjacently while intersecting each other and are positioned between the two first dripper members (110), so that the dripper body (100) can have a minimum volume as illustrated in FIG. 6.
[0033] The mounting wing (200) is formed as an integral part with the aforementioned dripper body (100) as illustrated in FIGS. 1 to 3 and FIGS. 5 to 8, and allows the dripper body (100) to be mounted on the cup (10), and can be folded to be adjacent to the first dripper body (110) like the second dripper member (120). At this time, the mounting wing (200) can be folded so as to be positioned within the range of the first dripper member (110) when folded, so that the present invention can be folded to have the size of the first dripper member (110) as illustrated in FIG. 6 even though the mounting wing (200) is formed as an integral part with the dripper body (100), thereby improving portability. The present invention, folded to have a minimum volume in this way, can be stored in a case (300) as illustrated in FIG. 6 so as to prevent arbitrary unfolding.
[0034] The holding wing (200) may include a first holding wing (210) that is formed integrally with the second dripper member (120) as illustrated in FIGS. 1 to 3 and protrudes outward from the folding line (121). The first holding wing (210) may be formed in various shapes, but is preferably formed in the shape of a right triangle with a diagonal side positioned at the folding line (121) so as to be positioned on the inside of the second dripper member (120) when the second dripper member (120) is folded and not to protrude outward from the first dripper member (110). The second dripper member (120) is positioned adjacently between two first dripper members (110) in a folded state, and the first holding wing (210) is positioned adjacently between the folded second dripper members (120), so that the first holding wing (210) can be seen as being folded adjacent to the first dripper member (110). In addition, when the dripper body (100) is folded, the user can easily unfold the dripper body (100) by pulling outward the two first holding wings (210) that are each integrally formed with the two second dripper bodies (100), so that the first holding wing (210) can serve as a handle for unfolding the folded dripper body (100).
[0035] This first holding wing (210) may have a first engaging groove (211) formed at the bottom, into which the upper end of the cup (10) is fitted, as illustrated in FIGS. 1 to 3 and 7. For example, a plurality of engaging grooves (211) may be formed along an edge slanted upward toward the outside of the first holding wing (210) that forms a right triangle shape with the oblique side arranged at the folding line (121). At this time, the engaging grooves (211) may be formed in the direction toward the oblique side, and it is preferable that the engaging length of the plurality of engaging grooves (211) be formed longer as the engaging grooves (211) are closer to the outer edge of the first holding wing (210), so that the dripper body (100) can be firmly fitted to the upper end of the cup (10). Through these plurality of engaging grooves (211), the dripper body (100) can be fitted to cups (10) of various sizes.
[0036] The holding wing (200) may include a second holding wing (220) that is provided to protrude outward from the boundary line (122) of the first dripper member (110) and the second dripper member (120) as illustrated in FIGS. 1 to 3 and FIG. 8. Specifically, the second holding wing (220) may be formed to have a width that becomes narrower as it goes downward. For example, the second holding wing (220) may have a fan shape with one side positioned on the boundary line (122), or may have a triangle shape with one side positioned on the boundary line (122) and the oblique side slanting upward toward the outside. A second hooking groove (221) may be formed on the second holding wing (220) so that the upper outer end forms a hook shape, and the upper end of the cup (10) may be fitted into the second hooking groove (221).
[0037] The second mounting wing (220) described above may not only form the mounting wing (200) alone, but may also form the mounting wing (200) together with the first mounting wing (210). In this case, the first mounting wing (210) may be provided to protrude outward from the center of the folding line (121), and the second mounting wing (220) may be provided to protrude outward from the lower portion of the boundary line (122). And the first holding wing (210) arranged on the folding line (121) of one second dripper member (120) and the second holding wing (220) arranged on each boundary line (122) of two first dripper members (110) adjacent to the second dripper member (120) can be formed by folding one wing member and joining it to form an integral part with the second dripper member (120).
[0038] The present invention, which has a second holding wing (220) in addition to a first holding wing (210), allows the upper end of the cup (10) to be fitted into the first holding groove (211) and the second holding groove (221), so that the dripper body (100) can be stably and firmly held. In addition, since the held dripper body (100) does not touch the extracted coffee liquid, a set amount of coffee liquid can be extracted, and since the upper end of the cup (10) and the dripper body (100) are separated by the holding wing (200), the amount and concentration of the extracted coffee liquid can be easily checked with the naked eye.
