Abstract
Description
Technical Field
[0001] This invention relates to the field of pharmaceutical packaging technology, and in particular to a packaging structure and method for fine powdered traditional Chinese medicine. Background Technology
[0002] In the field of packaging and administration of finely powdered traditional Chinese medicine, there are specific needs for powders with certain special properties. Finely powdered traditional Chinese medicines such as lyophilized leech powder, lyophilized American ginseng powder, and bear bile powder are characterized by high value and high perishability. Currently, the industry commonly uses vials (injection vials) for packaging them. Vials possess an airtight system consisting of a neutral borosilicate glass body, butyl rubber stopper, and aluminum cap, providing excellent moisture and oxidation protection for the medicines and effectively extending their shelf life.
[0003] However, vials have significant drawbacks. When patients open a vial and directly ingest the powder, the experience is unpleasant, especially when faced with a strong fishy or bitter taste, making swallowing difficult. There are also risks of choking, powder contamination, and inaccurate dosage. To facilitate patient administration, ordinary Chinese medicine powders are usually pre-filled into capsules. However, capsule shells have a certain degree of moisture and air permeability. For fine powders that require extremely strict storage conditions, quality deterioration may still occur during long-term storage, failing to provide the stable protection offered by vials. Furthermore, the traditional method of wrapping powders in glutinous rice paper also has inherent drawbacks, including cumbersome operation, the tendency for the powder to stick together with saliva, leading to swallowing hazards, and difficulty in accurately controlling the dosage.
[0004] This reveals a clear contradiction in existing technologies: vials excel in storage but lack convenience in administration; capsules are easy to take but unsuitable for long-term storage of such fine powders. Currently, the market lacks a solution that perfectly combines these two aspects of storage and administration. Summary of the Invention
[0005] The present invention aims to at least improve one of the technical problems existing in the prior art. To this end, the present invention proposes a packaging structure and packaging method for fine powders of traditional Chinese medicine.
[0006] The technical solution of the present invention is as follows: A packaging structure and method for fine powdered traditional Chinese medicine, comprising: Multiple packaging units are connected sequentially to form a rectangular shape, with serrated creases at the joints between adjacent packaging units.

[0007] In one possible technical solution, the capsule further comprises a capsule body and a capsule cap, wherein the outer diameter of the capsule body is the same as the inner diameter of the mouth of the vial, thereby preventing the powder from spilling during the transfer of fine Chinese medicine powder and improving the airtightness during the transfer process.
[0008] In one possible technical solution, a ring-shaped flange is further provided on the inner wall of the vial near the mouth; The outer wall of the capsule has a ring-shaped groove that fits with the ring-shaped flange to form a locking structure, thereby creating a closed channel for the transfer of fine Chinese medicine powder from the vial to the capsule, preventing the powder from spilling.
[0009] In one possible technical solution, the annular flange and the annular groove are of the same size, 1mm to 1.5mm, to prevent them from falling off.
[0010] In one possible technical solution, the inner diameter of the capsule cap is 0.1 mm to 0.2 mm larger than the outer diameter of the capsule, so as to facilitate the nesting of the two to form a cavity structure of the capsule.
[0011] In one possible technical solution, a ring-shaped concave edge is provided 0.5mm to 0.6mm away from the opening of the capsule cap, which can form a capsule locking structure with the ring-shaped groove of the capsule body.
[0012] In one possible technical solution, the vial is further described as having a butyl rubber stopper and an external aluminum-plastic composite cap.
[0013] In one possible technical solution, the capsule is further selected from gelatin capsules, hydroxypropyl methylcellulose capsules, and pullulan capsules.
[0014] A method for packaging fine powdered traditional Chinese medicine, wherein the fine powdered traditional Chinese medicine is subjected to secondary packaging before consumption using the above-mentioned packaging structure, including the following steps: S1, Open: Break the back seal of any packaging unit and remove the seal of the vial; S2, Connection: Remove the capsule cap and capsule body, align the capsule body opening vertically and fit it inside the glass bottle mouth of the vial; S3, Transfer: Hold the connection between the vial and the capsule, and flip the vial to transfer the powder into the capsule. Specifically, flip the entire device smoothly 180 degrees. You can gently tap the bottom of the vial to allow all the powder in the vial to be completely transferred into the capsule under the action of gravity. S4, Capsule preparation: Remove the capsule already filled with medicinal powder, put on a capsule cap to form a capsule locking structure, and obtain a standard capsule containing fine Chinese medicine powder.
[0015] In one possible technical solution, further, in S2, the annular flange is made to fit into the annular groove by pressing down and rotating.
[0016] The packaging structure and method for fine powdered traditional Chinese medicine according to the present invention have the following beneficial effects: 1. Perfect combination of storage and administration: The medicine is kept in an optimal inert and airtight environment in the vial before administration, and is transferred to the capsule only when needed, thus balancing long-term stability and ease of use.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.
[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0032] The terms "first," "second," "third," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects and not to describe a particular order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, it may include a series of steps or units, or optionally, steps or units not listed, or other steps or units inherent to these processes, methods, products, or devices. (Computer Template) The accompanying drawings show only the portions relevant to this application, not all of them. Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe operations (or steps) as sequential processes, many of these operations may be performed in parallel, concurrently, or simultaneously. Furthermore, the order of the operations may be rearranged. The process may be terminated when its operation is completed, but may also have additional steps not included in the drawings. The process may correspond to a method, function, procedure, subroutine, subprogram, etc.
[0033] The terms “component,” “module,” “system,” “unit,” etc., used in this specification are used to refer to computer-related entities, hardware, firmware, combinations of hardware and software, software, or software in execution. For example, a unit can be, but is not limited to, a process running on a processor, a processor, an object, an executable file, a thread of execution, a program, and / or distributed between two or more computers. Furthermore, these units can be executed from various computer-readable media on which various data structures are stored. Units can communicate, for example, via local and / or remote processes based on signals having one or more data packets (e.g., data from a second unit interacting with another unit between a local system, a distributed system, and / or a network; for example, the Internet interacting with other systems via signals).
[0034] Example 1 like Figures 1 to 7As shown, this embodiment details a packaging structure specifically designed for fine powdered traditional Chinese medicine. The structure mainly comprises multiple separable packaging units 1, which are sequentially connected and arranged in a regular rectangular array through precise design. Fine serrated creases are specially designed between adjacent packaging units 1, facilitating easy tearing off of individual packaging units 1 as needed while maintaining the integrity and aesthetics of the overall packaging. Each packaging unit 1 specifically includes: a molded blister pack 10 with two independent slots inside, namely an vial slot and a capsule slot; a robust back seal layer 11 tightly covering the surface of the blister pack 10 to completely seal the vial slot and capsule slot, ensuring the sterility and moisture protection of the internal components; a vial 12 pre-filled with fine powdered traditional Chinese medicine, securely placed in the vial slot with a sealed opening; and an empty capsule 13 placed in the capsule slot, the capsule having a hollow internal structure for subsequent filling with powder transferred from the vial.
[0035] In a preferred embodiment, the capsule 13 is further designed to include two parts: a capsule body 131 and a capsule cap 132. The outer diameter of the capsule body 131 is consistent with the inner diameter of the mouth of the vial 12. This dimensional consistency design ensures that the two parts can fit tightly together during powder transfer, thereby significantly reducing powder spillage and greatly improving the sealing and reliability of the transfer operation.
[0036] In another improved design, a tiny annular flange structure is machined on the inner wall of the vial 12 near the mouth; correspondingly, a corresponding annular groove is formed on the outer surface of the capsule 131. These two structures can match each other and form an effective locking mechanism. When the powder is transferred from the vial 12 to the capsule 131, this structure can create a completely sealed channel, thereby preventing leakage or scattering of the powder during transfer, further ensuring the cleanliness and precision of the operation.
[0037] In a more specific implementation, the dimensions of the aforementioned annular flange and annular groove are controlled to be exactly the same, preferably with a width between 1 mm and 1.5 mm. This precise dimensional control ensures sufficient tightness when the two are engaged, preventing accidental loosening during use, and also avoids problems with poor fit caused by dimensional deviations.
[0038] Furthermore, the inner diameter of the capsule cap 132 is slightly larger than the outer diameter of the capsule body 131, with the difference controlled within the range of 0.1 mm to 0.2 mm. This subtle difference allows the capsule cap 132 to be easily and stably fitted onto the outside of the capsule body 131, thereby forming a complete and sealed capsule cavity, while ensuring ease of assembly and the integrity of the final product.
[0039] In addition, an annular groove is provided about 0.5 mm to 0.6 mm inward from the opening of the capsule cap 132. When the capsule cap 132 is fitted with the capsule body 131, this groove can lock with the annular groove on the capsule body 131 to form an additional capsule locking structure, thereby further enhancing the sealing and stability of the capsule 13 before use and preventing leakage of contents.
[0040] Regarding the sealing method of vial 12, this embodiment prioritizes the use of butyl rubber stoppers for internal sealing, and adds an aluminum-plastic combination cap on the outside to ensure that the medicine is not affected by environmental factors during storage and maintain the stability of the drug efficacy.
[0041] Meanwhile, the material of Capsule 13 can be selected according to actual needs, such as gelatin capsules, hydroxypropyl methylcellulose (HPMC) capsules, or pullulan polysaccharide capsules, to adapt to different drug properties and individual patient needs, thereby improving the applicability and flexibility of the overall packaging.
[0042] Example 2 This embodiment further clarifies a packaging method for finely powdered traditional Chinese medicine. This method, based on the aforementioned packaging structure, enables a convenient and safe secondary repackaging of the finely powdered traditional Chinese medicine before consumption. The method specifically includes the following steps: S1, Opening Operation: The user first tears off the individual packaging unit along the serrated crease, then carefully breaks open its back seal and removes the sealing components on the vial to prepare for the subsequent transfer of powder; S2, Connection Operation: Remove the capsule cap and capsule body from the capsule slot, align the opening of the capsule body precisely with the glass mouth of the vial at a vertical angle, and gently press to gradually fit the capsule body onto the mouth of the vial, ensuring that the two are tightly connected. S3, Transferring the powder: Hold the part where the vial and the capsule connect firmly with your hand, and then rotate the entire device smoothly 180 degrees. During this process, you can gently tap the bottom of the vial. With the help of gravity, all the powder in the vial will be completely and accurately transferred into the capsule. S4, Capsule preparation: Remove the capsule filled with medicinal powder from the mouth of the vial, then put the capsule cap on the capsule body and fix it with a locking structure to finally form a complete capsule containing a standard dose of fine Chinese medicine powder, which can be taken directly.
[0043] In a more optimized operating method, during the connection process described in step S2, the user can slightly press down and simultaneously rotate the capsule to make the annular flange of the vial mouth completely fit with the annular groove on the capsule, thereby further enhancing the connection stability and providing better sealing for the transfer step.
[0044] To verify the beneficial effects of the present invention, the following specific implementation examples are provided: Case 1: Packaging for freeze-dried leech powder Packaging components: This product uses 2ml neutral borosilicate glass vials with a compact design, offering excellent chemical stability and sealing. Each vial contains 0.25g of high-purity lyophilized leech powder, processed using a freeze-drying process to preserve the raw material's biological activity. The vial opening is initially sealed with a 20mm butyl rubber stopper, whose excellent elasticity and airtightness effectively isolate it from external air and moisture. An outer aluminum cap provides a secondary, reinforced seal, ensuring the integrity and safety of the contents during storage and transportation.
[0045] Meanwhile, the packaging uses No. 0 hollow gelatin capsules, the material of which meets pharmaceutical standards, is easy to swallow, and dissolves quickly in the body. Precise measurements have been taken to ensure the vial opening has an outer diameter of Φ13.00mm and an inner diameter strictly controlled at Φ7.35±0.03mm, guaranteeing a perfect fit with the capsules. The capsule body's opening also has an outer diameter of Φ7.35±0.03mm and features a ring-shaped flange structure on the outside, allowing the capsule to securely lock into place at the vial opening and preventing loosening or detachment.
[0046] Overall Packaging Solution: One bottle of freeze-dried powder and one matching capsule are packaged together in a single blister pack. The blister pack is made of a composite material of rigid plastic and aluminum foil, providing excellent moisture resistance and pressure resistance. Every 10 blister packs are packaged together with a detailed illustrated instruction manual in a custom outer box, forming a complete course of treatment packaging. This facilitates patients' use according to the treatment plan and enhances the product's professional image and credibility.
[0047] Instructions for use: Patients can easily transfer the lyophilized powder into capsules by simply following the instructions shown in the diagram. The entire process requires no special tools and is quick and easy. Due to the closed transfer method, the drug's odor is completely isolated, achieving odorless medication and significantly improving the user experience. Experimental verification shows that this packaging design has a transfer efficiency exceeding 99.5%, minimizing drug residue and ensuring accurate dosage.
[0048] Case 2: Packaging for American Ginseng Ultrafine Powder Packaging components: This product uses a 3ml neutral borosilicate glass vial, which offers high transparency and heat resistance. The vial is filled with 0.4g of ultrafine American ginseng powder, processed using ultrafine pulverization technology to produce fine particles that are easily absorbed by the body. The vial is tightly sealed with a 20mm butyl rubber stopper, which meets pharmaceutical-grade standards and will not react with the drug components. An aluminum cap further enhances the overall sealing and anti-counterfeiting features.
[0049] The accompanying capsules are made of No. 00 hollow hydroxypropyl methylcellulose (HPMC) capsules, a plant-based material suitable for vegetarians and those sensitive to animal-derived ingredients, exhibiting excellent biocompatibility and solubility. Precise measurements show the vial opening has an outer diameter of Φ15.00mm and an inner diameter of Φ8.25±0.03mm. The capsule opening is correspondingly designed with an outer diameter of Φ8.2±0.03mm and features an annular flange on the inner side, ensuring an interference fit between the capsule and the vial opening, enhancing connection stability and sealing performance.
[0050] Packaging Design: The outer packaging uses environmentally friendly and recyclable paper materials. It has a sturdy structure and a simple design. The surface is printed with a green logo, highlighting the product concept of naturalness, health and sustainable development, and catering to modern consumers' pursuit of environmental protection and healthy living.
