Description

Portable coffee dripper

The present invention relates to a portable coffee dripper, and more particularly, to a portable coffee dripper that is foldable and thus convenient to carry while ensuring a sufficient extraction time.

In general, a coffee dripper is a tool that can simply extract coffee concentrate by placing it on top of a cup. However, existing coffee drippers have the problem of being difficult to carry because they are made of hard materials such as plastic and glass.

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”).

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 bag containing coffee powder inside while being supported by the frame (16), 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 does not have sufficient flavor.

Korean Patent Registration No. 10-0255123 'Coffee Package'

The present invention is intended to solve the above problems and to provide a portable coffee dripper that is foldable and thus convenient to carry, while ensuring sufficient extraction time to extract coffee liquid with a rich taste and aroma.

The present invention proposes a portable coffee dripper, which comprises: a dripper body including two first dripper members, which are foldable and conveniently portable, and which secure a sufficient extraction time to extract coffee liquid having a rich taste and aroma; and two second dripper members which respectively connect the side ends of the two facing first dripper members, and which has at least one extraction hole formed at the bottom; and a mounting wing which 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 can be folded so as to be adjacent to the first dripper member.

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.

Hereinafter, the portable coffee dripper of the present invention will be described in detail with reference to the attached drawings 1 to 9.

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.

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 used, a coffee filter can be spread out on the inside and coffee powder can be accommodated in the spread 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.

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) that 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.

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 with 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.

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.

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) positioned 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.

The mounting wing (200) is formed as an integral part with the 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 member (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 even though the mounting wing (200) is formed as an integral part with the dripper body (100), the present invention can be folded to have the size of the first dripper member (110) as illustrated in FIG. 6, 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 not to be arbitrarily unfolded.

The mounting wing (200) may include a first mounting 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 mounting wing (210) may be formed in various shapes, but is preferably formed in the shape of a right triangle with a diagonal side arranged on 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 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). Thus, the first holding wing (210) can be viewed as being folded adjacently 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). The first holding wings (210) can serve as a handle for unfolding the folded dripper body (100).

As shown in FIGS. 1 to 3 and 7, the first mounting wing (210) may have a first engaging groove (211) formed at the bottom into which the upper end of the cup (10) is fitted. For example, a plurality of engaging grooves (211) may be formed along an edge slanted upward toward the outside of the first mounting wing (210) that forms a right triangle shape with the hypotenuse arranged at the folding line (121). At this time, the engaging grooves (211) may be formed in the direction toward the hypotenuse, and it is preferable that the engaging grooves (211) of the plurality of engaging grooves (211) be formed so that the engaging length thereof is longer as the engaging grooves (211) are closer to the outer edge of the first mounting wing (210), so that the dripper body (100) may be firmly fitted to the upper end of the cup (10). Through the plurality of engaging grooves (211), the dripper body (100) may be fitted to cups (10) of various sizes.

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 hypotenuse 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).

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). At this time, 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).

The present invention, which has a second holding wing (220) along with 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.
