Description

Multi-layer coffee filter

This creation is related to coffee filter appliances, and more specifically to a multi-layer coffee filter with a double filter effect of coffee grounds.

According to the conventional method of manual foaming and brewing coffee, the filter cup with a plurality of perforations on the bottom is placed on the cup, and the filter paper folded into a funnel is placed in the filter cup, and then Appropriate amount of coffee powder is placed in the filter paper, and then the hot water of predetermined temperature is slowly and spirally poured onto the coffee powder, and the coffee liquid is extracted, and the coffee liquid gradually passes through the perforation of the filter paper and the filter cup to the cup. In-house, available for drinking.

The filter paper used in the extraction of coffee is mainly used to block coffee grounds, and can absorb the grease in coffee, which is very convenient to use. However, since filter paper is made of ordinary paper, it is made of plants such as trees. It is less environmentally friendly. Even if it is recycled from recycled paper, it still increases the cost of recycling. It is obviously still improved.

In order to solve the above problems, coffee filter devices that do not need to use filter paper have been developed by the industry, such as the patent of the Republic of China No. M307371 "filter cup for double-layered cup double-layer filter".

The previously disclosed patent mainly restricts the coffee powder between the two filters, so that the coffee powder can be completely poured by hot water to extract a better concentration of the coffee liquid. Although it has two filters, when brewing coffee, only the lower filter is actually performing the filter of coffee slag. Therefore, it is inevitable that some coffee slag will remain in the coffee liquid, and the coffee slag is filtered. The effect is not very sure.

The main purpose of this creation is to provide a multi-layer coffee filter that can solve the problem of the previous lack of coffee, which can brew coffee without using filter paper, and can generate multiple filtering of coffee grounds to achieve environmental protection for reducing trees such as felled trees. Benefits, and indeed the filtration effect of blocking the flow of coffee slag, the practical value is very good.

The reason is that, in order to achieve the above objectives, the present invention provides a multi-layer coffee filter comprising a cup body, comprising a cup body, a tapered shell shape which is open at one end and tapers from the open end toward the other end, and is surrounded by The bottom end is provided with a plurality of perforations, a cup of mouth ring is arranged at the open end of the cup body, and a grip is protruded from the mouth ring of the cup; a filter screen is placed on the inner side of the cup body.

Further, the cup and the screen are made of a metal material.

Further, the mouth ring system comprises a ring piece, and the grip is formed on the outer edge of the ring piece, and a flange is bent on the inner edge of the ring piece to abut the cup body for clamping the screen.

Further, a bottom ring is further included and is fixed on the closed end of the cup body for clamping one end edge of the filter net to the bottom ring of the cup and the cup body. Between the ends.

Further, the bottom ring of the cup comprises a bottom ring, which is substantially in the form of a sheet, is fixed on the closed end of the cup body and presses the filter screen, and a pressing edge is disposed on the upper edge of the bottom ring and abuts against the cup body. The wall is pressed against the filter.

Preferably, the perforation diameter of the closed end of the cup is larger than the perforation diameter around the cup.

The second drawing is a top view of a preferred embodiment of the present invention.

The third drawing is a bottom view of a preferred embodiment of the present invention.

The fourth drawing is a state diagram of the use of a preferred embodiment of the present invention.

In the following, a preferred embodiment of the present invention will be described in detail with reference to the drawings:

First, referring to the first to third figures, the multi-layer coffee filter 10 of the preferred embodiment of the present invention comprises a cup 12 made of a metal material, a screen 14 and a bottom ring 16.

The cup 12 is composed of a cup body 22, a cup mouth ring 24 and a grip 25. The cup body 22 has a top end opening, a conical shell shape that tapers from the open end 26 (top end) toward the closed end 28 (bottom end), and a plurality of perforations 30, 32 are provided around the closed end 28 to make the cup The body 22 is also of a mesh type, and the perforation 32 of the closed end 28 is larger than the perforation 30 around the cup 22. path. The cup mouth ring 24 is disposed at the open end 26, and has a ring piece 34 and a flange 36 bent on the inner edge of the ring piece 34. The flange 36 is fast against the inner side of the cup body 22, and the grip 25 is protruding. It can be held on the outer edge of the ring piece 34.

The screen 14 abuts against the inside of the cup body 22, and the mesh has a caliber to block the passage of the coffee grounds, and the upper edge thereof is sandwiched between the flange 36 and the inner wall of the cup body 22.

The cup bottom ring 16 is fixed to the inside of the closed end 28 of the cup body 22 and has a bottom ring 38 and a pressing edge 40. The bottom ring 38 is substantially in the form of a sheet, and is fixed to the inner wall of the closed end 28 to press the filter screen 14. The pressing edge 40 is attached to the upper edge of the bottom ring 38 and abuts against the inner wall of the cup body 22 to press the filter screen 14. The bottom end of the screen 14 can be clamped and fixed between the bottom ring 16 and the closed end 28.

According to the above configuration, when the multi-layer coffee filter 10 is used, it can be placed on a filter cup 1 (inserted in the filter cup 1 or mounted on the cup mouth of the filter cup 1 by the ring piece 34, depending on the filter cup 1 The cup 1 is placed on the cup 2, as shown in the fourth figure, and then a proper amount of coffee powder is placed directly into the cup 12, followed by a predetermined temperature of hot water. Slowly drenched on the coffee powder, as in the conventional method of manually extracting coffee, the coffee liquid can gradually drip through the filter screen 14, the perforations 30, 32 and the filter bowl 1 in the cup 2 (each of the closed ends 28) The perforation 32 is larger than the perforation 30 around the cup 22, so that most of the coffee liquid flows out through the perforations 32.

Therefore, the multi-layer coffee filter 10 of the present invention can at least achieve the following characteristics and effects:

The multi-layer coffee filter 10 has a structure of filtering the coffee grounds by the cup body 22 and the filter screen 14, and can surely achieve the filtering effect of preventing the coffee slag from flowing into the filter cup 1, thereby replacing the use of the conventional coffee filter paper. It is very environmentally friendly to reduce the cutting of trees and other plants, and the upper edge and the bottom end of the filter screen 14 are pressed by the flange 36 and the pressing edge 40 respectively, and the cleaning is also convenient. Of course, it is also possible to provide two or more layers of the filter screen 14 in the cup body 12.

Secondly, the cup body 22 is of a conical shell shape, and the cup mouth ring 24 of the open end 26 is further provided with a protruding grip 25, so that it can be placed on the filter cup 1 of different calibers, which is convenient for the user. The action of extracting coffee is carried out in a traditional manual manner.

It can be seen from the above that the multi-layer coffee filter provided by the present invention can surely achieve the filtering effect of blocking the flow of coffee slag by using the filter structure of the cup body and the filter screen, and can be extracted without using the conventional filter paper. Coffee has been used to reduce the environmental benefits of tree felling, and its practical value is very good. The reason is that this creation does meet the requirements of the new patent and submits an application according to law.

However, the above is only one of the best examples of this creation. When it is not possible to limit the scope of the patent protection of this creation, the simple equivalent change and replacement according to the scope of the patent application and the content of the manual. , shall remain within the scope of protection covered by the scope of this patent application.
