Description

Hand-punched strip filter cup

The present invention relates to a filter cup, and in particular to a hand-punched strip-hole coffee filter cup.

Hand-washed coffee has opened the era of coffee aesthetics. People can enjoy the feeling of concentration, mystery, expectation and romance during the brewing process, and they can taste the delicious food that comes with it. The coffee is rich in fat, but it is sour and bitter, the shade is adjustable, and the hand-washing filter cup is cheap, the brewing conditions are simple, the playability and the controllability are strong, and the hand-operated coffee is more and more popular among modern people. The essential tool for hand-operated coffee – the role of the filter cup in this is especially important.

In the prior art, the cup hole of the coffee filter cup is mostly round, specifically, the circular filter hole is matched with the cup bottom of the perfect circle, and there are more or less problems of the filter cup regardless of the number of holes, for example: Porous round filter cup, the flow rate is fast, so it needs to be filled several times after steaming, so to get a mellow coffee, you need to have good control techniques for the number of water injections and water injection, and these are for beginners or ordinary people. It is not particularly practical for consumers. For a circular single-hole filter cup, the problem of slower drop rate and easy blockage is often generated. Moreover, such filter cups also cause uneven flow of coffee into the bottom of the cup, which ultimately affects the taste of the coffee.

The technical problem to be solved by this creation is to provide a hand-punched strip-shaped coffee filter cup which has a moderate filtering speed, is not easy to be clogged, and can brew a delicious coffee without much skill.

In order to solve the above problems, the technical solution adopted by this creation is:

The utility model relates to a hand-punching strip-shaped hole filter cup, which comprises a cup body and a cup bottom, wherein the cup bottom has a filter hole, the filter hole is an elongated strip shape, and the cup body is a flat cone cup body which is upper and lower, The cup body and the cup bottom are connected to form a rectangular inner side of the cup bottom, and the outer side of the cup bottom has a boss disposed around the filter hole, and the inner wall of the cup is provided with a linear guide groove from top to bottom.

Preferably, the bottom of the cup has an elongated filter hole.

Preferably, the bottom of the cup has two rectangular filter holes arranged in a line.

Preferably, the flow guiding grooves are evenly arranged on the inner wall of the cup.

Preferably, the cup bottom is a round cup bottom, and the cup bottom has a diameter larger than a minimum inner diameter of the cup body.

Preferably, the filter bowl is a ceramic filter cup, and a cup handle is further disposed outside the cup body.

Preferably, the boss is a circular boss, and the filter hole has an area of 1/2 or more of the total area of the inner side of the cup.

Compared with the prior art, the beneficial effects achieved by the present creation are:

The filter cup of this creation has a good extraction effect for various roasted coffees. The bottom filter hole is long and the filter hole is moderate in area. This design avoids the trouble of excessive flow rate of the porous filter bowl. The utility model solves the problem that the strip-shaped filter cup is easy to be blocked, and the narrow-shaped filter hole is also more conducive to the concentration of the coffee, and is convenient for the full extraction of the coffee; the flat-conical cup body design is matched with the straight line of the cup body from top to bottom. The type of diversion trough not only facilitates the accumulation of coffee under the cup, but also facilitates the effective elimination of hot gas during the brewing process, thereby avoiding the appearance of volcanic bubbles in the steaming.

After repeated tests, it was found that the long strip-shaped filter hole combined with the flat-conical cup body design is more conducive to coffee extraction than the traditional round filter hole with the conical cup body, and the flow rate of coffee from the top to the bottom of the cup is more uniform. The brewed coffee beans, the same brewing technique, the coffee extracted by the filter cup in this creation has a better taste.

The creation is further described below in conjunction with the drawings. The following examples are only used to more clearly illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention.

Example 1

As shown in Figures 1 to 3, a hand-punched strip-shaped filter cup includes a cup body 1 and a cup bottom 2, the cup bottom 2 has a filter hole 5, the filter hole 5 is elongated, and the cup body 1 is large. The lower flat conical cup has a cross section that gradually transitions from a top to a bottom into a rectangular shape from top to bottom. The cup body 1 and the bottom 2 of the cup form a rectangular inner side of the bottom of the cup, and the outer side of the bottom of the cup has a boss 3 disposed around the filter hole 5. The boss 3 can also have a certain guiding effect on the coffee during extraction and filtration, and the cup body The wall is provided with a linear guide groove from top to bottom. Preferably, the bottom of the cup has an elongated filter aperture.

Specifically, the flow guiding grooves 11 are evenly arranged in the inner wall of the cup. The cup bottom 2 is a round cup bottom, and the diameter of the cup bottom is larger than the smallest inner diameter of the cup 1. The filter bowl is a ceramic filter cup. The ceramic material has good heat preservation and heat resistance, and the fragrance is more complete. A cup handle 4 is also provided on the outside of the cup. The boss 3 is a circular boss, and the area of the filter hole 5 is about 1/2 of the total area of the inner side of the bottom of the cup.

In actual use, the hand-punched strip-shaped filter cup in this embodiment is used in conjunction with the fan-shaped filter paper to exert an optimum effect.

Example 2

As shown in Fig. 4, in the embodiment 2, the cup bottom has two rectangular filter holes 51 which are arranged in a row, and the filter hole area accounts for 2/3 of the inner side of the cup bottom. In this embodiment, the ceramic thickness is 4 mm, convex. The height of the table 3 is 10 mm, the cup wall of the cup 1 is at an angle of 65 degrees with respect to the plane, and the minimum inner diameter of the bottom of the cup 1 is about 1/2 of the maximum inner diameter of the top of the cup. The rest of the design is the same as in Embodiment 1.

The above description is only a preferred embodiment of the present invention, and it should be noted that those skilled in the art can make several improvements and modifications without departing from the principles of the present invention. It should be considered as the scope of protection of this creation.
