Description

Technical Field

[0001] The invention relates to the technical field of food processing, and more specifically to a food capsule capable of being brewed. Background Art

[0002] Capsule brewing machines are becoming more and more popular due to their small size and easy operation. Coffee capsules are made by specially processing coffee beans into coffee powder and then sealing them in capsules, making it convenient for people to use when extracting coffee. At the same time, the capsules are filled with non-toxic inert gas to extend the shelf life and prevent oxidation and bacterial growth. When coffee needs to be brewed, the coffee capsule is pierced through the capsule brewing machine for extraction.

[0003] Commonly used capsule brewing machines use a brewing chamber upper and lower or horizontal mechanism to clamp the capsule for piercing and extracting coffee. For example, Chinese utility model patent application CN103479224A discloses a small manual pressure coffee pot, including a filter cup, a piston pressure pump contained in the filter cup, and a coffee box assembly. First, the coffee capsule is placed in the coffee powder box and tightly installed at the bottom of the filter cup. Then the filter cup is installed on the pot body, and boiling water is poured into the filter cup. The pot cover is installed, and the piston is pressed. The boiling water is pressed into the coffee powder box at the bottom of the filter cup. After filtering, concentrated coffee can be made. This structure has the following problems: the overall structure has many parts, occupies a large space, and is inconvenient to install and disassemble.

[0004] Therefore, the existing patent No. WO2019 / 192264A1 discloses a coffee capsule, in which food-grade particles are arranged between the filter and the closed end. The food-grade particles have edges and corners. Although the structure is simple and easy to disassemble, under the pressure of water, the food-grade particles can not only pierce the closed end, but also pierce the filter, affecting the filtering effect. Summary of the invention

[0005] In view of this, the present invention proposes a brewable food capsule, comprising a first chamber 10 and a second chamber 30, wherein the first chamber 10 contains brewable food, one end of the first chamber 10 is covered with a first sealing film 20, the first sealing film 20 is used for injecting a solution for brewing food after being punctured, and the other end is connected and sealed with one end of the second chamber 30, the other end of the second chamber 30 is provided with a closed end 40, the closed end 40 is used for discharging the solution for brewing food after being punctured, a circle of connecting steps 50 is provided at the connection between the first chamber 10 and the second chamber 30, a filter membrane 60 is provided at the connecting step 50, the filter membrane 60 is used to isolate the first chamber 10 and the second chamber 30 to form independent chambers, and at the same time isolate the brewed food residues in the first chamber 10 and filter the brewed solution into the second chamber 30, the structure can prevent the filter membrane 60 from being punctured by arranging the filter membrane 60 between the first sealing film 20 and the closed end 40, and effectively filter the brewable food.

[0006] A food capsule for brewing includes a first chamber 10 and a second chamber 30, wherein the first chamber 10 contains brewable food, one end of the first chamber 10 is covered with a first sealing film 20, the first sealing film 20 is used for injecting a solution for brewing food after being punctured, and the other end is connected and sealed with one end of the second chamber 30, the other end of the second chamber 30 is provided with a closed end 40, the closed end 40 is used for discharging the solution for brewing food after being punctured, and is characterized in that: a circle of connecting steps 50 is provided at the connection between the first chamber 10 and the second chamber 30, a filter membrane 60 is provided at the connecting step 50, and the filter membrane 60 is used to isolate the first chamber 10 and the second chamber 30 to form independent chambers, and at the same time isolate the brewed food residues in the first chamber 10 and filter the brewed solution into the second chamber 30.

[0007] Furthermore, the first chamber 10 and the second chamber 30 are both truncated cone-shaped, and the connecting surfaces of the first chamber 10 and the second chamber 30 are the same in size.

[0008] Furthermore, the first chamber 10 and the second chamber 30 are made of transparent material, so that the condition of the brewable food can be easily observed. When the brewable food is tea leaves, the quality of the tea leaves, such as the shape and color, can be seen.

[0009] Furthermore, the first chamber 10 and the second chamber 30 form a funnel shape that gradually shrinks from top to bottom.

[0010] Furthermore, the first sealing film 20 and the closed end 40 are both easily punctured structures.

[0025] like Figure 1-4As shown, a capsule for brewing food includes a first chamber 10 and a second chamber 30. The first chamber 10 and the second chamber 30 are both truncated cone-shaped. The connecting surfaces of the first chamber 10 and the second chamber 30 are the same in size. The first chamber 10 contains brewing food. The first chamber 10 and the second chamber 30 are made of transparent materials, which are easy to observe the brewing food. When the brewing food is tea, the quality of the tea, such as the shape and color, can be seen. The first chamber 10 and the second chamber 30 form a funnel shape that gradually shrinks from top to bottom.

[0026] One end of the first chamber 10 is covered with a first sealing film 20, which is used to inject a solution for brewing food after being punctured. The other end is sealedly connected to one end of the second chamber 30. The other end of the second chamber 30 is provided with a closed end 40, which is used to discharge the solution for brewing food after being punctured. Both the first sealing film 20 and the closed end 40 are easily punctured structures.

[0027] A circle of connecting steps 50 is provided at the connection between the first chamber 10 and the second chamber 30, and a filter membrane 60 is provided at the connecting step 50. The diameter of the filter membrane 60 is larger than the inner diameter of the connecting step 50 and smaller than the outer diameter of the connection between the first chamber 10 and the second chamber 30. The filter membrane 60 is used to isolate the first chamber 10 and the second chamber 30 to form independent chambers, while isolating the brewed food residues in the first chamber 10 and filtering the brewed solution to the second chamber 30.

[0028] The connection method between the filter membrane 60 and the connection step 50 is one of ultrasonic welding and hot stamping.
