Abstract
Description
[Technical Field]
[0001] The present invention relates to a filter holder used for dripping coffee, black tea, green tea, etc. using a filter or the like. [Background technology]
[0002] For example, drip coffee is known, in which coffee powder is placed in a bag-shaped filter and hot water is slowly poured over it to extract the coffee. In this case, it is necessary to hold the paper filter so that it does not fall off due to the weight of the hot water poured into it, and various holders have been proposed.
[0003] However, most of the holders proposed so far have a three-dimensional structure, which requires a large space for storage and transportation, and they are difficult to clean after use and inconvenient to handle, especially when used outdoors.
[0004] Therefore, for example, Patent Document 1 discloses a drip tool that is made up of an annular support frame. The annular support frame disclosed in the publication holds a filter by pressing a pair of protrusions on the left and right sides from both sides to widen the gap inside the protrusions. This requires pressing the pair of protrusions with one hand while pinching both ends of the filter with the other, making it difficult to handle. [Prior art documents] [Patent documents]
[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2018-134158 Summary of the Invention [Problem to be solved by the invention]
[0006] An object of the present invention is to provide a filter holder that is easy to handle, carry, and clean after use. [Means for solving the problem]
[0007] The filter holder of the present invention is composed of a plate body and is characterized by having a filter mounting opening for inserting and mounting the filter from above, and a support groove for supporting the folded portion of the filter.
[0008] Here, being made up of a plate body means that the filter holder is made of a plate material, and that even if there are local irregularities or bent portions, the filter holder is in a plate shape overall. Coffee drip filters are often paper filters that are unfolded into a cone shape when used, but when sold they are folded into a flat fan shape or similar for storage. Therefore, when the paper filter is folded, folds are formed on both sides. Therefore, the filter holder according to the present invention is used by inserting the folded portion between the support grooves.
[0009] Therefore, in the present invention, it is preferable that the plate body has a first support groove and a second support groove that are cut out on both sides of the filter mounting opening and are arranged opposite each other.
[0010] Furthermore, it is preferable that the length L of the plate body in the direction of the first and second support grooves is greater than the width W perpendicular to the length L. This allows for a wide range of coffee cup sizes to be used, from large to small. [Effects of the Invention]
[0011] The filter holder according to the present invention is constructed of a plate body, so it does not require a large space for storage or transportation, and is easy to handle during and after use. [Brief explanation of the drawings]
[0012] [Figure 1] 1A is a perspective view of a filter holder according to the present invention, and FIG. 1B is a plan view thereof. [Figure 2] (a) shows the filter holder placed on the opening of a coffee cup and the paper filter being attached from above, and (b) shows the attached state. [Figure 3] Shows hot water being poured from above and dripping. [Figure 4] (a) is a plan view of the filter holder with a paper filter attached and coffee powder added, and (b) is a side view. DETAILED DESCRIPTION OF THE INVENTION
[0013] FIG. 1(a) shows a perspective view of a filter holder 10 according to the present invention, and FIG. 1(b) shows a plan view thereof. The filter holder 10 is composed of a plate body 11 having a plate shape as a whole. The plate body 11 has a circular filter mounting opening 12 formed in the center, and a first support groove portion 13a and a second support groove portion 13b formed as elongated holes cut out opposite each other on both sides of this filter mounting opening 12.
[0014] In this embodiment, as shown in FIG. 1(b), the length L dimension along the arrangement direction of the first support groove portion 13a and the second support groove portion 13b is set to be larger than the width W dimension perpendicular to it.
[0015] In the embodiment shown in FIG. 1, the outer shape is elliptical, but the plate may be rectangular or polygonal, or may have an irregular shape resembling various animals or characters. In this embodiment, taking into consideration the size of commercially available coffee cups, L is 100 to 150 mm, W is 60 to 80 mm, and the inner diameter of the filter mounting opening 12 is 45 to 55 mm. The first and second support groove portions 13a, 13b have a groove width of 6 to 10 mm and a notch length of 10 to 20 mm. The thickness is 0.5 to 2 mm.
[0016] The plate body 11 may be made of a metal material such as stainless steel, aluminum, or tin, which can be reused repeatedly, or may be made of a resin material. If it is sufficient to use it once or multiple times, it may be made of paper.
[0017] Next, a usage example will be described. As shown in Figure 2, the paper filter 2 has a bag-shaped opening 2a and a bottomed bottom 2d, and is often folded so that folds 2b and 2c are formed on both sides, and is folded into a fan shape in which the dimension on the opening side is longer than the length of the bottom 2d. The filter holder 10 is placed on the opening of the coffee cup 1, and the filter is attached by inserting it from above into the filter attachment opening 12 while widening the gap between the opposing pieces 2e and 2f of the opening so that the folded portions 2b and 2c on both sides of the paper filter are inserted and supported by the first support groove portion 13a and the second support groove portion 13b, respectively.
[0018] Next, pour hot water from pot 3 over the top as shown in Figure 3. At this time, as shown in Figure 4, hot water is poured onto the coffee grounds 4, and the weight of the poured water causes the grounds 4 to sink downward. However, as shown in Figure 4(b), the folded portions 2b, 2c on both sides of the paper filter 2 widen in size from the bottom 2d toward the upper opening, so the folded portions also widen, and once they have dropped a predetermined amount, they are supported and held by the first and second support groove portions 13a, 13b on both sides. This allows the hot water to be poured slowly and the coffee to be extracted. In this way, the first support groove portion 13a and the second support groove portion 13b are shaped like long holes cut out to a specified width and length, so when hot water is poured into them, the fold portion widens slightly along the groove width as shown in Figure 4(a), and is supported on the bottom side of the groove, so that the holder is held stably even if it is a plate body. Therefore, there is no need to pinch the fold portion as in the cited document 1. [Explanation of symbols]
