Description

Technical Field

[0001] This utility model relates to the technical field of beverage capsules filled with extracts, and specifically to an extract capsule for traditional Chinese medicine components. Background Technology

[0002] As a type of device that uses a capsule structure as the extraction medium, capsule extraction equipment uses a piercing needle to penetrate the sealing film at the top of a beverage capsule during use. Liquid at a set temperature and pressure is injected into the capsule, and the effective ingredients in the capsule contents are extracted through pressure impregnation extraction to obtain the corresponding beverage.

[0003] In traditional technologies, the capsule structures used in this type of capsule extraction equipment are mostly rigid or semi-rigid, with relatively simple structures. They are mainly used for the rapid preparation of beverages such as milk tea, finished tea, and coffee. The beverage materials are mostly in powder form in the capsules, so the corresponding capsule structure only needs to ensure pressure resistance.

[0004] With the continuous improvement of people's living standards and the increasingly fast pace of life, more and more people are seeking more convenient healthy beverage options. Health tea drinks, as a natural and healthy beverage, have gained widespread popularity. To meet this market demand, some health tea drinks have begun to use capsule extraction equipment for production. This equipment can quickly and efficiently extract the effective components from health tea while maintaining the natural flavor and nutritional value of the beverage. However, in the process of processing health tea drinks into powder, problems such as increased processing costs and loss of effective components arise. These problems not only increase production costs but may also affect the quality and efficacy of health tea drinks, thus limiting their further development and popularization.

[0005] Therefore, a novel capsule extraction structure is needed to meet the specific needs of traditional Chinese medicine components. Utility Model Content

[0006] The technical problem solved by this utility model is to provide an extraction capsule for traditional Chinese medicine components, which can solve the defects in the above-mentioned technical background.

[0007] The technical problem solved by this utility model is achieved by the following technical solution:

[0008] An extraction capsule for traditional Chinese medicine components, comprising a capsule body and a filter element;

[0009] The capsule body is made of rigid plastic. The inner side of the capsule body has a volumetric cavity with an open top surface, which is sealed by a sealing film layer. A hole seat is formed at the bottom center of the volumetric cavity. A through hole is formed at the center of the hole seat, which is connected to the volumetric cavity at the top. A concentric ring seat is formed on the outer side of the hole seat. The ring seat is composed of multiple limiting bracket units, and adjacent limiting bracket units have a connecting part.

[0010] The filter element is T-shaped, with an assembly hole formed in the middle of the vertical side that matches the seat. The filter element is assembled onto the seat by pressure through the assembly hole, and the filter element in the assembled state rests against the upper surface of the ring seat through the lower surface of the horizontal side.

[0011] The extraction capsule uses the area between the sealing membrane, filter element, and ring seat in the volumetric cavity as the filling space for the Chinese medicine components.

[0012] As a further limitation, the plastic material of the capsule body is made of polycarbonate; the filter element is made of food-grade PP material.

[0013] As a further limitation, the volumetric cavity is preferably a cylindrical structure cavity with a circular cross-section, and the ratio of the outer diameter to the height of the cylindrical structure cavity is between 1:1 and 2:1.

[0014] As a further limitation, the outer surface of the capsule body has a tapered structure with a larger outer diameter at the top and a smaller outer diameter at the bottom. At the same time, the outer edge of the upper surface of the capsule body has a stepped edge to facilitate the positioning of the capsule body on the extraction equipment. The sealing film layer is formed integrally with the capsule body at the stepped edge by hot pressing.

[0015] As a further definition, the sealing film layer is a multi-layer composite food preservation film layer, specifically including a polyethylene layer, an aluminum foil layer, and a polypropylene layer, wherein the polyethylene layer is located in the outermost layer, the aluminum foil layer is located in the middle layer, and the polypropylene layer is located in the innermost layer.

[0016] As a further limitation, a buffer gap is reserved between the inner wall of the ring seat and the outer diameter of the filter element in the assembled state, and the ring width of the buffer gap is preferably 2 to 5 mm.

[0017] As a further limitation, the height of the ring seat in the volumetric cavity is 1 / 3 to 3 / 5 of the height of the volumetric cavity; and in the filter element assembly state, the distance between the upper surface of the filter element and the lower surface of the sealing membrane layer is 1 / 3 to 1 / 2 of the height of the volumetric cavity.

[0018] As a further limitation, the limiting bracket unit has a reinforcing rib formed on its inner side that is connected to the bottom surface of the capsule body.

[0019] As a further limitation, the inner wall of the volumetric cavity of the capsule body may be coated with a food-grade anti-stick coating to prevent the Chinese medicine components from adhering to the inner wall during the extraction process.

[0020] As a further limitation, the Chinese herbal medicine component filled in the filling space is Chinese herbal medicine powder or dried fragments or a combination of both, the weight of the Chinese herbal medicine component filled in a single extraction capsule is 10-30g, and the filling volume is no more than 80% of the volume of the drug filling cavity; and the volume cavity of the capsule body is also encapsulated with an inert gas to preserve the stored Chinese herbal medicine component.

[0021] Beneficial effects: The extraction capsule for traditional Chinese medicine components of this invention has a better preservation effect, effectively preventing the influence of light and oxygen on the components and extending the shelf life of the herbal beverage. Simultaneously, by setting a combination of a perforated seat and a ring seat at the bottom center of the capsule body, and fixing the filter element's position through this combination, the filter element remains stable during extraction, avoiding uneven extraction caused by filter element movement. Furthermore, by reserving a buffer gap between the ring seat and the perforated seat, vibrations and impacts generated during extraction can be effectively absorbed, thereby ensuring the structural strength of the capsule body and its stability during high-pressure extraction.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0025] See Figure 1 A preferred embodiment of an extraction capsule for traditional Chinese medicine components. In this embodiment, the extraction capsule is used to contain traditional Chinese medicine components 10 of a health tea. The weight of the traditional Chinese medicine components 10 filled in a single extraction capsule is 15g per cup, which is used for single-cup extraction on an extraction device.

[0026] The extraction capsule of this embodiment includes an independently formed capsule body 2, a sealing membrane layer 3, and a filter element 9. When in use, the filter element 9 is first pressed into the capsule body 2. After assembly, a fixed amount and proportion of traditional Chinese medicine components 10 are dispensed. After nitrogen filling, the capsule body 2 is heat-pressed and sealed using the sealing membrane layer 3 to form a complete extraction capsule.

[0027] The capsule body 2 of the extraction capsule is made of polycarbonate, which possesses excellent mechanical strength and heat resistance, enabling it to withstand the high temperature and high pressure environments encountered during the extraction process. The volumetric cavity 4 of the body 2 is shaped like an inverted frustum, with a perfectly circular cross-section at any point, and the ratio of its outer diameter to its height is between 1.5:1 and 1.2:1, gradually decreasing from top to bottom. This volumetric design not only ensures the stability of the capsule but also improves the extraction efficiency.

[0028] The capsule body 2 is designed with a combination of a perforated seat 8 and a ring seat 5 at the bottom center of the volumetric cavity 4. The perforated seat 8 and the ring seat 5 are formed together with the capsule body 2. Accordingly, the perforated seat 8 and the ring seat 5 are concentrically arranged, with the perforated seat 8 located inside and the ring seat 5 surrounding it. A through hole 7 is designed in the center of the perforated seat 8. The through hole 7 has a liquid outlet 11 formed at the bottom and is connected to the volumetric cavity 4 at the top. The ring seat 5 is composed of multiple limiting bracket units, which are evenly arranged on the corresponding annular surface of the ring seat 5, and adjacent limiting bracket units have a connecting portion.

[0029] The outer surface of the capsule body 2 is designed with a tapered structure, wider at the top and narrower at the bottom, which facilitates the positioning of the capsule body on the extraction equipment. The outer edge of the upper surface of the capsule body 2 has a stepped edge 1, and the sealing film layer 3 is integrally formed with the capsule body 2 by hot pressing, ensuring the sealing performance of the capsule.

[0030] The sealing film layer 3 is a multi-layered composite preservation film, including a polyethylene layer, an aluminum foil layer, and a polypropylene layer, with the polyethylene layer on the outermost layer, the aluminum foil layer in the middle layer, and the polypropylene layer on the innermost layer. This structure not only effectively isolates external light and oxygen but also ensures the preservation effect of the Chinese herbal component 10 during the extraction process, extending the shelf life of the Chinese herbal beverage.

[0031] Filter element 9 is molded from food-grade PP material, possessing excellent chemical stability and heat resistance, enabling it to withstand the high-temperature environment during extraction. During assembly, filter element 9 is stably fixed to the orifice seat 8 via pressure fitting. Filter element 9 is T-shaped, with a matching mounting hole formed in the middle of its vertical side. The filter element is pressure-fitted onto the orifice seat 8 through this mounting hole. In the assembled state, filter element 9 rests against the upper surface of the ring seat 5 via the lower surface of its horizontal side. A 3mm buffer gap is maintained between the inner wall of the orifice seat 8 and the outer diameter of the assembled filter element 9 to ensure stability during extraction and prevent uneven extraction caused by filter element movement.

[0032] In this embodiment, the corresponding limiting bracket unit in the hole seat 8 has a reinforcing rib 6 formed on the inner side that is connected to the bottom surface of the capsule body 2. The reinforcing rib 6 can further strengthen the structural strength of the capsule body 2 and ensure the stability of the capsule body during high-pressure extraction.

[0033] The filling space of the extraction capsule is the area between the sealing membrane layer 3, the filter element 9, and the ring seat 5 in the volumetric cavity 4. This area is used to fill the traditional Chinese medicine component 10. In this embodiment, the height of the ring seat 8 in the volumetric cavity 4 is 1 / 2 of the height of the volumetric cavity; while in the assembled state of the filter element 9, the distance between the upper surface of the filter element 9 and the lower surface of the sealing membrane layer 3 is 2 / 5 of the height of the volumetric cavity. This size configuration can ensure the uniform distribution and effective extraction of the traditional Chinese medicine component 10 during the extraction process.

[0034] In another embodiment, a food-grade anti-stick coating can be applied to the inner wall of the volumetric cavity 4 to prevent the encapsulated Chinese herbal component 10 from adhering to the inner wall of the volumetric cavity 4 during the extraction process, thereby further improving the extraction efficiency and the ease of use of the capsule.

[0035] The Chinese herbal component 10 filled in the filling space is Chinese herbal powder, crushed dry material, or a combination of both. The filling volume does not exceed 80% of the volume of the filling cavity, ensuring extraction efficiency and the quality of the Chinese herbal beverage. In addition, the volume cavity 4 of the capsule body 2 is also encapsulated with an inert gas to preserve the stored Chinese herbal component 10. In this embodiment, the inert gas is nitrogen gas introduced during the nitrogen filling process as described above, to prevent the Chinese herbal component 10 from oxidizing and deteriorating during storage.

[0036] In this embodiment, during the extraction process, the extraction equipment uses a piercing needle to penetrate the sealing membrane layer 3 and inject liquid at a set temperature and pressure into the internal volumetric cavity 4 of the capsule. The effective components of the traditional Chinese medicine component 10 within the capsule are extracted through pressure impregnation extraction, and the extracted liquid is discharged from the outlet 11 to obtain the corresponding beverage. Throughout the extraction process, the combination of the perforated seat 8 and the ring seat 5 located at the bottom center of the capsule body 2, along with the stable positioning of the filter element 9, effectively absorbs vibrations and impacts during extraction, ensuring the structural strength of the capsule body 2 and its stability during high-pressure extraction.

[0037] In summary, the extraction capsule of this invention not only has a good preservation effect, but also ensures the stability and efficiency of the extraction process through structural design, while reducing production costs, improving the quality and efficacy of health tea beverages, meeting market demand, and having broad market application prospects.
