Description

Immersion coffee filter cup

The present invention relates to a coffee filter cup, especially an immersed coffee filter cup which can hold coffee powder and soak the coffee powder in coffee liquid to fully extract the coffee essence.

There are many ways for consumers to drink coffee. In addition to buying bottled and canned coffee, they can also buy coffee powder ground from their favorite coffee beans and brew it with hot water.

One of the ways to brew coffee is to use a French filter press. When brewing, first put an appropriate amount of coffee powder in the filter press, and then inject hot water with a temperature of about 90 to 95 degrees into the filter press. In the pot, let it stand for 4 to 5 minutes, let the coffee powder absorb water and expand and release the coffee essence, then push down the rod to drive the filter to press down the coffee grounds formed by the coffee powder extraction to the bottom of the pot, and then you can Pour the filtered coffee into a cup to drink. Although the above-mentioned method of brewing coffee with a French filter press can prolong the soaking time to fully extract the oil and various soluble substances contained in the coffee powder, so as to obtain a cup of coffee with a mellow taste, in order to reduce the effect of the filter on the The resistance to movement in the filter press pot is that the pores on the filter screen are relatively large, so it is often impossible to completely filter the coffee grounds in the coffee liquid, so as to affect the taste of the drinker when drinking coffee.

In order to avoid drinking coffee grounds and affecting the taste, in recent years, it is common to brew coffee with a drip method. , and then put the coffee powder on the filter paper, and then inject hot water. After the coffee powder absorbs water and expands and releases the coffee essence to form coffee liquid, the coffee liquid is dripped into the lower cup from the filter cup for subsequent drinking. The coffee grounds formed after extraction of the ground coffee remain on the filter paper. Although the coffee brewed by the above drip filtration method can completely filter the coffee grounds to obtain a cup of coffee with a clear taste, the contact time between the hot water and the coffee powder is short, so the The fat and various soluble substances are fully extracted, so that the brewed coffee has the problem of lower body.

In view of the aforementioned problems in the prior art, the purpose of the present invention is to provide an immersion coffee filter cup, which can soak the coffee powder in the coffee liquid when brewing and extract the coffee, so as to fully extract the coffee essence and improve the coffee The mellow taste, while avoiding the problem of turbid taste caused by the mixed coffee grounds in the coffee liquid.

In order to achieve the above-mentioned creative purpose, the technical means adopted by the present invention is to make an immersion coffee filter cup include: A main cup has a filter cartridge, a bottom plate and a ring bracket, a peripheral edge of the bottom plate is connected to a lower peripheral edge of the filter cartridge, the ring bracket is arranged on an upper edge of the filter cartridge, and runs along the filter cartridge. The radial direction of the cartridge protrudes outward, wherein the filter cartridge has a lower ring portion and an upper ring portion, the lower ring portion is not formed with any pores, and the upper ring portion is formed on the lower ring portion and the upper edge of the filter cartridge between, and a plurality of perforations are arranged, and the height of the ring portion under the filter cartridge accounts for 1/3 to 2/5 of the overall height of the filter cartridge; A filter screen, which is arranged on the inner ring wall surface of the filter cylinder of the main cup body, and correspondingly covers the upper ring portion of the filter cylinder formed with perforations, the filter screen is formed with a plurality of filter holes, each of the filter screen The diameter of a filter hole is smaller than the diameter of each perforation of the filter cartridge 11 of the main cup body.

In the infusion coffee filter cup, the aperture of each perforation formed on the upper ring portion of the filter cartridge of the main cup body can be 0.5 millimeters (milimeter, mm).

In the infusion coffee filter cup, the mesh of the filter screen can be 800.

In the infusion type coffee filter cup, the ring bracket of the main cup body can have an extension frame plate and a ring frame plate, the extension frame plate laterally extends from the upper edge of the filter cartridge toward the outer side of the filter cartridge , the ring frame plate is bent relative to the extension frame plate from the outer periphery of the extension frame plate and further extended.

In the infusion type coffee filter cup, the upper edge of the filter cylinder of the main cup body is opened around an upper end of the filter cylinder, and the ring frame plate of the ring bracket of the main cup body can open toward the upper end of the filter cylinder extends in the direction it faces.

With the above-mentioned design, when the brewing coffee filter cup of the present invention is used for brewing coffee, the coffee powder contained in the filter cartridge of the main cup body can remain immersed in the coffee liquid in the cup, so as to continue. The extraction of the coffee components is carried out, so that the coffee essence is fully released, and the coffee grounds formed after the extraction of the coffee powder are stopped by the lower ring of the filter cartridge and retained in the filter cartridge. After the predetermined soaking time is over, the user only needs to pick up the infusion coffee filter cup of the present invention from the cup, and then the coffee grounds and the coffee liquid can be separated, so as to obtain a cup of coffee with a mellow taste and no contamination due to sufficient extraction. Delicious coffee with a crumb and a clear taste.

The technical means adopted by the present invention to achieve the predetermined purpose of the invention are further described below with reference to the drawings and preferred embodiments of the present invention.

Referring to FIGS. 1 and 2 , the infusion coffee filter cup of the present invention includes a main cup body 10 and a filter screen 20 .

Referring to FIG. 3A , the main cup body 10 has a filter cartridge 11 , a bottom plate 12 and a ring bracket 13 . The filter cartridge 11 has an upper edge and a lower edge, the upper edge surrounds an upper end opening of the filter cartridge 11 , and the lower peripheral edge surrounds a lower end opening of the filter cartridge 11 . A peripheral edge of the bottom plate 12 is connected to the lower peripheral edge of the filter cartridge 11 to close the lower end opening of the filter cartridge 11 . The ring bracket 13 is disposed on the upper periphery of the filter cartridge 11 and protrudes outward along the radial direction of the filter cartridge 11 .

Referring to FIG. 3A and FIG. 3B , the filter cartridge 11 has a lower ring portion 111 and an upper ring portion 112 , the lower ring portion 111 is a complete sheet body without any pores, and the upper ring portion 112 is formed in the lower ring A plurality of perforations 113 are arranged between the portion 111 and the upper edge of the filter cartridge 11, so that the distance from the lower edge of the filter cartridge 11 to the upper edge is the overall height H of the filter cartridge 11, and the lower ring portion 111 and the The distance from the junction of the upper ring portion 112 to the lower peripheral edge of the filter cartridge 11 is the height H1 of the lower ring portion 111 , wherein the height H1 of the lower ring portion 111 of the filter cartridge 11 accounts for 1 of the overall height H of the filter cartridge 11 . /3 to 2/5. In the specific embodiment of the present invention, the diameter of each through hole 113 formed on the upper ring portion 112 of the filter cartridge 11 is 0.5 millimeters (milimeter, mm).
