Description

Beverage filter

The present invention relates to the preparation of brewing or infusion of beverages such as coffee and tea, and more particularly, the invention relates to brewing and soaking devices which comprise a filter for isolating solid materials in the prepared beverage, To get a drink.

People have enjoyed coffee drinks since the ninth century, and have tried many brewing and soaking techniques for many years. Brewing and soaking can be achieved by adding hot water to a seasoning solid such as tea or coffee powder. The beverage is to be in an ideal state by giving sufficient time for the optimal aroma to be released from the flavored solids and incorporated into the water, and then stopping the soaking process to remove the flavored solids from the water to control the flavoring solids to be excessive Extract to release a strong or unpleasant taste such as bitterness in coffee.

In today's brewing techniques, stopping the soaking process requires removal of the filter device from the beverage, which often causes inconvenience and inconvenience to the user. In addition, most soaking techniques require a preparation device that is separate from the drinking device. Furthermore, when the beverage preparation is completed, most of the products on the market do not provide proper insulation for the beverage.

Coffee is made by grinding coffee beans into small particles and brewing them to form a coffee beverage. In a certain amount of coffee, the finely ground powder will be twice as fine as the coarsely ground particles. Therefore, the finely ground powder can be brewed quickly. However, the coffee standard The device must have a filter to block the penetration of smaller substances from the finely ground powder into the beverage.

Coffee contains small molecules of oil to make coffee taste creamy, which is ideal for gourmet coffee. Usually the lipid molecules have a diameter of about 0.4 mm. There is therefore a need for an invention that allows a beverage to be soaked in a convenient device that can be used as both a beverage brewer and a drinking cup. Ideally, such an invention should consist of two cups, an inner cup and an outer cup, wherein the inner cup has a filter for the passage of lipids, but does not allow the flavored solids or residue to enter the prepared beverage. . This need is met in the present invention.

SUMMARY OF THE INVENTION A primary object of the present invention is to provide a beverage filtering device for use in brewing or soaking beverages such as coffee and tea, which includes a filter that isolates the solid material in the prepared beverage to obtain a beverage.

In order to achieve the above object and effect, a beverage filtering device of the present invention comprises an outer cup; an inner cup having a diameter slightly smaller than the outer cup, so that the inner cup can be inserted into the outer cup, and the lower surface of the inner cup is a reduced diameter portion a seal can be assembled to form a seal between the inner and outer surfaces of the outer cup; a bottom of the inner cup is provided with a filter having an annular body defining an interior space for flavoring The solids are stored in the interior space, while the top forms a plurality of perforations for the passage of small molecular substances of the flavoring solid, without allowing large particles of the flavoring solid to pass through the perforations to obtain a beverage.

Figure 5 shows a cross-sectional view of the coffee powder particles resting in the ring body of the filter.

Referring to FIG. 1 to FIG. 3, the beverage filtering device 10 of the present invention comprises an outer cup 20, an inner cup 30 and an upper cover 40. The outer cup 20 is made of a rigid material such as stainless steel, and the outer cup 20 is a cylinder. shape.

The inner cup 30 is made of a rigid material such as stainless steel, and the inner cup 20 is cylindrical and has a diameter slightly smaller than the outer cup 20 so that the inner cup 30 can be inserted into the outer cup 20.

FIG. 2 is an exploded perspective view of the inner cup 30. The underside of the inner cup 30 is a reduced diameter portion 31 which can be fitted with a sealing ring 32 for preventing the flavoring solids from flowing out between the outer cup 20 and the inner cup 30. The bottom of the inner cup 30 is provided with a filter 33 which is screwed into the bottom of the inner cup 30. The filter 33 has an annular body 34 for storing flavored solids such as ground coffee granules in the interior space 35 of the annular body 34, while the top portion forms a plurality of perforations 36 for the passage of grease, such as brewed coffee, without allowing seasoning. Large particles of solids pass through the perforations 36. An annular flange 37 is formed at the bottom of the annular body 34. When the filter 33 is fitted into the reduced diameter portion 31 of the inner cup 30, the annular flange 37 can be brought against the bottom edge of the reduced diameter portion 31.

3 is an exploded perspective view of the beverage filtering device 10 of the present invention showing the relationship between the outer cup 20, the inner cup 30 and the upper cover 40.

Referring to FIG. 1 , the beverage filtering device 10 of the present invention further includes an upper cover 40 and a tightly coupled outer cup 20 . The upper cover 40 can be combined with the outer cup 20 by inserting or screwing. The present invention is described by way of a thread. . The upper cover 40 can be made of a rigid material such as stainless steel or plastic. The upper cover 40 has a venting opening 41.

Figure 4 shows a cross-sectional view of the inner cup 30 fully inserted into the outer cup 20. Preferably, the outer cup 20 and the inner cup 30 are preferably cylindrical, and the inner cup 30 has a diameter slightly smaller than the outer cup 20 so that the inner cup 30 can be fitted into the outer cup 20. The seal ring 32 surrounds the reduced diameter portion 31 of the inner cup 30, and when the inner cup 30 is inserted into the outer cup 20, a seal is formed between the inner cup 30 and the inner surface of the outer cup 20. Therefore, when the inner cup 30 is gradually pushed into the outer cup 20, the liquid of the outer cup 20 is forced to pass through the perforations 36 of the filter 33 into the inner cup 30.

The following describes how to use the beverage filtering device 10 of the present invention to pour an appropriate amount of material, such as ground coffee, into the outer cup 20, and add an appropriate amount of hot water to complete the brewing process. After a predetermined time, the inner cup 30 is inserted into the outer cup 20 and gradually pushed down, and the coffee granules 50 are allowed to rest in the inner space 35 of the annular body 34 of the filter 33 to allow the prepared coffee beverage to The coffee granules 50 are isolated, and the coffee beverage can be directly consumed by completing the above preparation, as shown in FIG. In addition, the internal space 35 of the filter 33, in addition to the liquid which can store the seasoning solids and remains in the internal space 35 for a long time, does not mix and pour out when pouring the liquid of the inner cup 30 to ensure the inner cup. The liquid concentration and taste of 30 are the same.
