Description

Technical Field

[0001] This utility model relates to the field of tea capsule technology, and in particular to a high-barrier tea capsule. Background Technology

[0002] In the modern convenient beverage industry, tea capsules, as an emerging method of tea drinking, are favored by consumers for their ease of use and rapid extraction. Tea capsules are made by specially processing tea leaves into raw materials and then sealing them in a sealed capsule space, while also filling it with inert gas to extend shelf life. To use them, simply place them in a dedicated tea brewing machine, which punctures the capsule to extract the tea, quickly producing a cup of tea. However, in existing tea capsules, after the brewing machine punctures the capsule, water flows directly into the capsule at high pressure and speed, rapidly contacting the tea leaves. This rapid water flow causes the tea leaves to tumble violently inside the capsule, resulting in unstable contact between the tea leaves and the water outlet, causing fluctuations in extraction pressure. This leads to insufficient and uneven extraction, and the rapid water flow also causes some tea leaves to not fully release their active ingredients due to insufficient contact time, while others are over-soaked, affecting the taste. Ultimately, the brewed tea has a poor flavor and fails to meet consumers' demand for high-quality tea. Therefore, there is an urgent need to design a high-barrier tea capsule to optimize the extraction process and improve the quality of the tea beverage. Utility Model Content

[0003] The purpose of this invention is to address the problem in the prior art where, during the tea brewing process, after the tea brewing machine punctures the capsule, water flows directly into the capsule with high pressure and speed, quickly contacting the tea leaves. This rapid water flow causes the tea leaves to tumble violently inside the capsule, making the contact surface between the tea leaves and the water outlet unstable, resulting in fluctuations in extraction pressure. Consequently, the tea leaves are not fully and evenly extracted. Furthermore, the rapid water flow causes some tea leaves to fail to release their active ingredients due to insufficient contact time with the water, while others are over-soaked, affecting the taste. Ultimately, the brewed tea has a poor flavor and fails to meet consumers' demand for high-quality tea. This invention proposes a high-barrier tea capsule.

[0004] The technical solution of this utility model is as follows: a high-barrier tea capsule, comprising: a capsule body, wherein a sealing ring is fixedly disposed inside the capsule body, the sealing ring dividing the interior of the capsule body into a buffer chamber and a material chamber; a protrusion is fixedly sleeved inside the sealing ring, wherein a plurality of water inlet holes are opened on one side of the protrusion, and a first barrier plate for blocking water flow impact is fixedly disposed on the inner wall of the protrusion.

[0005] Optionally, the water inlet port of the capsule body is provided with a water inlet membrane, which is made of a puncture-resistant membrane material that can be punctured by a tea brewing machine, and has a thickness between 0.1-0.3 mm.

[0006] Optionally, the water outlet port of the capsule body is provided with a sealing film, which is a multi-layer composite structure, including but not limited to a barrier layer and a heat-sealing layer.

[0007] Optionally, the water inlet connects the buffer chamber and the material chamber, and the water inlet is circular in shape with a diameter between 1 and 3 mm.

[0008] Optionally, a second barrier sheet is fixedly provided on the inner wall of the buffer cavity.

[0009] Optionally, a fixing plate is fixedly provided on the inner wall of the material chamber, and multiple water outlet holes are provided on the side of the fixing plate, which are arranged in a ring.

[0010] Optionally, the first and second barrier sheets are configured as spring-shaped structures.

[0011] In summary, this application includes at least one of the following beneficial technical effects:

[0012] This invention, by setting a first barrier plate on the inner wall of the convex cylinder and a second barrier plate on the inner wall of the buffer cavity, can effectively buffer the water flow after the tea brewing machine punctures the capsule, avoid the direct impact of large pressure and fast flow rate on the tea leaves, ensure that the tea leaves and water flow are in full contact, reduce the fluctuation of extraction pressure, thereby achieving more complete and uniform extraction of tea leaves and improving the taste of tea.

[0013] Furthermore, the capsule body is divided into a buffer chamber and a material chamber by a sealing ring, and the water inlet connects the two. Together with components such as the water inlet membrane and sealing membrane, the water flow into the capsule can be reasonably guided and controlled, so that the water flow comes into contact with the tea leaves at a more suitable speed and pressure. This makes the contact time between the tea leaves and the water flow more reasonable, so that the effective ingredients are not not fully released due to the contact time being too short, and the taste is not affected by over-soaking.

[0025] Example

[0026] like Figures 1 to 3As shown, this utility model proposes a high-barrier tea capsule, comprising: a capsule body 1, with a water inlet membrane 8 at the water inlet port. The water inlet membrane 8 is made of a puncture-resistant material that can be punctured by a tea brewing machine, and its thickness is between 0.1-0.3 mm. It can be precisely ruptured under the pressure of the tea brewing machine, allowing water to flow smoothly into the capsule. The capsule body 1 has a sealing film 9 at the water outlet port. The sealing film 9 has a multi-layer composite structure, including but not limited to a barrier layer and a heat-sealing layer. The barrier layer uses a high-barrier material to effectively block harmful gases such as oxygen and moisture, greatly delaying the oxidation and deterioration of the tea, and extending its shelf life. The heat-sealing layer has excellent heat-sealing performance and is tightly bonded to the capsule body through a hot-pressing process, forming a strong sealed structure. This ensures that the inside of the capsule remains sealed during transportation and storage, preventing tea leakage.

[0027] like Figure 2 and Figure 3 As shown, a sealing ring 2 is fixedly installed inside the capsule body 1. The sealing ring 2 divides the inside of the capsule body 1 into a buffer chamber 3 and a material chamber 4. The buffer chamber 3 is mainly used to buffer and initially guide the water flow entering the capsule. The second barrier 10 fixedly installed on its inner wall is a spring-shaped structure. When the water flow enters the buffer chamber, the second barrier 10 with the spring-shaped structure can effectively disperse the impact force of the water flow, avoid the water flow from directly causing a violent impact on the tea leaves in the material chamber, and prevent the tea leaves from being washed away and broken, thus affecting the shape and taste of the tea leaves when brewing.

[0028] Furthermore, the material chamber 4 is the core space for storing tea leaves, and the side of the fixing plate 11 fixedly installed on its inner wall has multiple annularly arranged water outlet holes 12. The annular arrangement of these water outlet holes 12 can make the brewed tea soup flow out evenly, avoiding inconsistent tea soup concentration due to uneven water output. At the same time, the fixing plate 11 also plays a role in supporting and fixing the tea leaves, keeping the tea leaves in a relatively stable state in the material chamber.

[0029] Furthermore, the convex cylinder 5, which is fixedly fitted inside the sealing collar 2, has multiple circular water inlet holes 6 on one side, with a diameter between 1-3 mm. The water inlet holes 6 connect the buffer chamber 3 and the material chamber 4. The appropriate hole size ensures that the water flows into the material chamber at an appropriate speed and flow rate, while preventing tea leaves from entering the buffer chamber through the water inlet holes. The first baffle 7, which is also a spring-shaped structure, is fixedly installed on the inner wall of the convex cylinder 5. It further buffers and organizes the water flow entering the material chamber, making the water flow contact the tea leaves more evenly, ensuring that the tea leaves can be fully soaked and release the best tea aroma and tea soup concentration.

[0030] The working principle of this embodiment is as follows: the tea capsule is placed into the capsule compartment of the appropriate tea brewing machine, at which time the water inlet of the capsule is aligned with the water injection device of the tea brewing machine, and the water outlet is facing the water outlet of the tea brewing machine.

[0031] When the tea brewing machine is started, the water flow generated by the water injection device impacts the inlet membrane 8. Since the inlet membrane 8 is made of a fragile membrane material with a thickness of 0.1-0.3mm, it is easily punctured. The water flow enters the buffer cavity 3 of the capsule body 1 through the puncture. Under the action of the second barrier plate 10 fixedly installed on the inner wall of the buffer cavity 3 and the first barrier plate 7 on the inner wall of the protrusion 5, the impact force of the water flow is effectively reduced, preventing the water flow from directly causing excessive impact on the tea leaves in the material cavity, and ensuring the integrity of the tea leaves.

[0032] After being buffered, the water flows smoothly into the material chamber 4 through the circular inlet 6 with a diameter between 1-3 mm on one side of the convex cylinder 5. The water makes full contact with the tea leaves in the material chamber 4, and the tea leaves begin to steep.

[0033] The liquid mixture after steeping tea leaves flows under pressure to the fixed plate 11 on the inner wall of the material chamber 4. It undergoes preliminary filtration through multiple water outlets 12 arranged in a ring on the side of the fixed plate 11, removing larger tea leaf fragments. Subsequently, the liquid continues to flow to the water outlet port of the capsule body 1.

[0034] Because the sealing membrane 9 at the water outlet has a multi-layered composite structure, including a barrier layer and a heat-sealing layer, it plays a good barrier role during the tea brewing process, preventing tea residue from entering the tea brewing machine's pipes. When the liquid reaches the sealing membrane 9, under the pressure of the tea brewing machine, the sealing membrane 9 is pushed open, and the filtered tea flows smoothly out of the capsule and into the teacup through the tea brewing machine's outlet, completing the tea brewing process.

[0035] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
