In this embodiment, each of the short ribs 3 is a short rib with the same thickness, but in other embodiments, the thicknesses of the plurality of short ribs 3 may be different. Therefore, each of the short ribs 3 has a maximum predetermined thickness T3 in practice, but the maximum predetermined thickness T3 is the same as the thickness of any part of the short ribs 3 in this embodiment, that is, this embodiment The maximum predetermined thickness T3 is the "thickness of the short rib 3".

The value of a maximum inner diameter 1D of the lower ring portion 1 minus twice the maximum predetermined thickness T3 is between 20 millimeters (mm) and 50 millimeters (mm), so that a plurality of the short ribs The thickness of 3 is less than 60% of the inner diameter (or caliber) of the lower ring part 1 , so that the lower ring part 1 can be called "large diameter" compared to the plurality of short ribs 3 . It should be noted that the lower ring portion 1 is a ring-shaped structure in this embodiment, therefore, the inner diameter of each position of the lower ring portion 1 is the same, that is, “the aforementioned lower ring portion 1 The “maximum inner diameter 1D” in this embodiment refers to “the inner diameter 1D of the lower ring portion 1”, but the present invention is not limited to this.

In order to more clearly describe the relationship between the aforementioned lower ring portion 1 (with the same inner diameter) and the plurality of the short ribs 3 (with the same thickness), an example will be described below. For example, when the inner diameter 1D (the maximum inner diameter) of the lower ring portion 1 is 100 millimeters (mm), the thickness of each of the short ribs 3 (the maximum predetermined thickness T3 ) should be between Between 25 millimeters (mm) and 40 millimeters (mm). It can be known from the inner diameter of the lower ring portion 1 and the thickness of the short ribs 3 that the thickness of the plurality of short ribs 3 is approximately less than about 60% of the inner diameter of the lower ring portion 1 . That is, the lower ring portion 1 for the coffee filter cup 100A of the present invention to flow out the coffee liquid has a large diameter. It should be noted that in practice, the maximum predetermined thickness T3 of each of the short ribs 3 is preferably between 0.5 millimeters (mm) and 15 millimeters (mm).

It should be noted that, referring back to FIG. 4 , when the upper ring portion 2 is in a transverse section along the extending direction of the overall length AL (or the central section line), the inner edge of the upper ring portion 2 has An included angle θ1 is between 50 degrees and 61 degrees. The included angle θ1 is a preferred angle designed for the above-mentioned technical solutions of "large diameter" and "short rib".

In other words, the coffee filter cup 100A of this embodiment is suitable for a coffee filter cup with an included angle θ1 between 50 and 61 degrees, and any coffee filter cup with an included angle θ1 is not the coffee referred to in this case. Filter bowl 100A. That is to say, the coffee filter cups with an included angle between 50 and 61 degrees cannot achieve the ideal technical effect of the present case in essence, although any technical solution in this case is applied.
