Description

Technical Field

[0001] This utility model relates to the field of capsule technology, and in particular to a plant-based hollow capsule. Background Technology

[0002] Empty capsules consist of a cap and a body, made from pharmaceutical gelatin and excipients. They are mainly used to contain solid and liquid medications, such as homemade powders, health products, and pharmaceuticals. They solve the problem of unpleasant taste and difficulty in swallowing, truly making good medicine palatable. Empty capsules are becoming increasingly popular. Firstly, their long and slender shape makes them easy to swallow, making them the most popular dosage form among consumers. Secondly, capsules can effectively mask the unpleasant taste and odor of the contents. A Chinese utility model patent, authorized publication number "CN216365988U", discloses a plant-based enteric-coated empty capsule, comprising an enteric-coated shell, a gelatin inner capsule, and an enteric-coated cap. The enteric-coated shell includes a first straight tube and a first annular recess. The gelatin inner capsule is embedded inside the first straight tube. The enteric-coated cap is fitted to one end of the enteric-coated shell. The enteric-coated cap includes a round cap, a second annular recess, and a second straight tube. The first straight tube and the second straight tube, as well as the first annular recess and the second annular recess, are axially fitted together.

[0003] The above-mentioned technical solution not only allows two solid drugs to be placed in the capsule according to a predetermined ratio and ensures that the two solid drugs are separated from each other, thus achieving a multi-purpose therapeutic effect, but also improves the reliability of the capsule after assembly by setting multiple limiting structures between the enteric shell and the enteric cap. However, the above-mentioned technical solution still has certain defects. When the structure is subjected to transportation bumps, due to the limited friction between the protrusions and grooves, the cap and body are prone to relative sliding when subjected to strong bumps. The two capsule shell sections of the cap and body may separate, resulting in drug leakage. The separation of the capsule shell may expose the drug to the air, affecting the drug's sealing and shelf life, causing the drug to become damp, oxidize, etc., thereby reducing the drug's stability. Therefore, this utility model proposes a new solution. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a plant-based hollow capsule that can solve the problem that when the structure is subjected to strong shocks during transportation, the cap and body are prone to relative sliding due to the limited friction between the protrusions and grooves, and the two capsule shell sections of the cap and body may detach, leading to drug leakage. The detachment of the capsule shell may expose the drug to the air, affecting the drug's sealing and shelf life, causing the drug to become damp, oxidize, etc., thereby reducing the stability of the drug.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a plant-based hollow capsule, comprising a capsule body and a capsule cap;

[0006] A capsule limiting assembly is disposed on the capsule body. The capsule limiting assembly includes a capsule body connecting ring, which is fixedly connected to the upper end of the capsule body.

[0007] The lower end of the capsule cap is fixedly connected to a capsule cap connecting ring, the inner wall of the capsule cap is fixedly connected to a fixing ring, and the outer surface of the capsule body connecting ring is provided with an annular first groove. The inner wall of the first groove is fixedly connected to multiple first expansion pieces.

[0008] The surface of the capsule body connecting ring is fitted with a second expansion piece, and both the first expansion piece and the fixing ring are engaged with the second expansion piece.

[0009] Preferably, the diameter of the capsule body connecting ring is smaller than the diameter of the capsule body, the diameter of the capsule cap connecting ring is larger than the diameter of the capsule cap, and the diameters of the capsule body and the capsule cap are the same.

[0010] Preferably, the cross-section of the first expansion piece is arc-shaped, and the fixing ring is circular in shape.

[0011] Preferably, the second expansion piece is V-shaped in general, and the lower end of the second expansion piece near the capsule body connecting ring is curled, while the side of the second expansion piece near the capsule cap is arc-shaped.

[0012] Preferably, the outer surface of the capsule body is provided with a plurality of sliding grooves and a plurality of second grooves;

[0013] The interiors of the multiple sliding grooves and the multiple second grooves are all arc-shaped, and the multiple sliding grooves are respectively connected to the corresponding second grooves.

[0014] Preferably, the inner wall of the capsule cap connecting ring is fixedly connected with multiple protrusions;

[0015] Multiple protrusions are slidably connected to their corresponding grooves, and multiple protrusions are engaged with their corresponding second grooves.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This plant-based hollow capsule, through the interlocking of a first expansion piece, a fixing ring, and a second expansion piece, facilitates the positioning of the capsule body and capsule cap. The second expansion piece increases the friction between the capsule body and capsule cap, effectively preventing the capsule cap from detaching directly, thus ensuring the integrity and structural stability of the capsule. The firm connection between the capsule body and capsule cap prevents leakage of the drug during storage and transportation, ensuring the drug's airtightness and shelf life, improving the drug's stability, and also avoiding waste or contamination caused by drug leakage.

[0018] 2. The plant hollow capsule, through the arc-shaped design of the first expansion piece and the curled design of the lower end of the second expansion piece, facilitates the reduction of resistance when the second expansion piece is fitted onto the surface of the capsule body connecting ring. When the second expansion piece is fitted onto the surface of the capsule body connecting ring, its curled lower end will squeeze the outer side of the first expansion piece, deforming it and causing elastic deformation, squeezing the first expansion piece into the interior of the first groove. When the second expansion piece passes over the first expansion piece, it will return to its original shape, making it easy to fit the second expansion piece onto the outside of the capsule body connecting ring. At the same time, the first expansion piece can block the upper end of the second expansion piece, preventing the second expansion piece from detaching from the capsule body connecting ring.

[0019] 3. In this plant-based hollow capsule, the second expansion piece is V-shaped. During the process of the capsule cap fitting with the capsule body, the capsule cap causes the fixing ring to slide on the surface of the second expansion piece. The fixing ring compresses the arc-shaped surface of the second expansion piece, causing it to elastically deform, making it easier to fit the capsule cap onto the capsule body. When the fixing ring passes the second expansion piece, the second expansion piece returns to its original shape. At the same time, the second expansion piece is blocked by the inner wall of the capsule cap, preventing it from fully returning to its original shape. The second expansion piece blocks the fixing ring, which is fixed to the inner wall of the capsule cap, preventing the capsule body and capsule cap from detaching during the fitting process. This improves the stability of the connection between the capsule body and capsule cap and enhances the sealing between them. Attached Figure Description

[0028] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0029] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] In the description of this utility model, terms such as greater than, less than, and exceeding are understood to exclude the stated number, while terms such as above, below, and within are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequential relationship of the indicated technical features.

[0031] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0032] Please see Figure 1-6 This utility model provides a technical solution: a plant hollow capsule, including a capsule body 1 and a capsule cap 2, and a capsule limiting component. The capsule limiting component is disposed on the capsule body 1 and includes a capsule body connecting ring 3, which is fixedly connected to the upper end of the capsule body 1. A capsule cap connecting ring 4 is fixedly connected to the lower end of the capsule cap 2. A fixing ring 7 is fixedly connected to the inner wall of the capsule cap 2. An annular first groove 5 is formed on the outer surface of the capsule body connecting ring 3. A plurality of first expansion pieces 6 are fixedly connected to the inner wall of the first groove 5. A second expansion piece 11 is sleeved on the surface of the capsule body connecting ring 3. The first expansion piece 6 and the fixing ring 7 are both engaged with the second expansion piece 11.

[0033] The engagement of the first expansion piece 6, the fixing ring 7, and the second expansion piece 11 facilitates the positioning of the capsule body 1 and the capsule cap 2. The second expansion piece 11 increases the friction between the capsule body 1 and the capsule cap 2, effectively preventing the capsule cap 2 from detaching directly, thus ensuring the integrity and structural stability of the capsule. The firm connection between the capsule body and the capsule cap prevents leakage of the drug during storage and transportation, ensures the sealing and shelf life of the drug, improves the stability of the drug, and also avoids waste or contamination caused by drug leakage.

[0034] The diameter of capsule body connecting ring 3 is smaller than the diameter of capsule body 1, the diameter of capsule cap connecting ring 4 is larger than the diameter of capsule cap 2, and the diameters of capsule body 1 and capsule cap 2 are the same.

[0035] The capsule body connecting ring 3 and capsule cap connecting ring 4 effectively enhance the overall structural stability of the capsule and prevent it from breaking during filling, transportation, or use. The design of these rings also helps the capsule body and capsule cap to fit together easily when needed. The capsule body connecting ring 3 ensures that the capsule body 1 can be tightly locked into the capsule cap 2 when fitted together, while the capsule cap connecting ring 4 ensures that the capsule cap 2 can be tightly locked into the capsule body 1 when fitted together, thus improving the stability of the connection between the capsule body 1 and the capsule cap 2, enhancing structural stability, and facilitating fitting together.

[0036] The first expansion piece 6 has an arc-shaped cross section, the fixing ring 7 is circular in shape, the second expansion piece 11 is V-shaped in shape, and the lower end of the second expansion piece 11 near the capsule body connecting ring 3 is curled, while the side of the second expansion piece 11 near the capsule cap 2 is arc-shaped.

[0037] The arc-shaped design of the first expansion piece 6 and the curled lower end of the second expansion piece 11 facilitate the reduction of resistance when the second expansion piece 11 is fitted onto the surface of the capsule body connecting ring 3. When the second expansion piece 11 is fitted onto the surface of the capsule body connecting ring 3, the curled lower end of the second expansion piece 11 will squeeze the outer side of the first expansion piece 6, deforming the first expansion piece 6 and causing it to undergo elastic deformation, thus squeezing the first expansion piece 6 into the interior of the first groove 5. When the second expansion piece 11 passes over the first expansion piece 6, it will return to its original shape, making it easy to fit the second expansion piece 11 onto the outside of the capsule body connecting ring 3. At the same time, the first expansion piece 6 can block the upper end of the second expansion piece 11, preventing the second expansion piece 11 from detaching from the capsule body connecting ring 3.

[0038] Because the second expansion piece 11 is V-shaped, during the process of the capsule cap 2 merging with the capsule body 1, the capsule cap 2 will cause the fixing ring 7 to slide on the surface of the second expansion piece 11. The fixing ring 7 will squeeze the arc-shaped surface of the second expansion piece 11, causing the second expansion piece 11 to undergo elastic deformation, making it easier to put the capsule cap 2 onto the capsule body 1. When the fixing ring 7 passes the second expansion piece 11, the second expansion piece 11 will return to its shape. At the same time, the second expansion piece 11 will be blocked by the inner wall of the capsule cap 2, so that the second expansion piece 11 cannot completely return to its shape. The second expansion piece 11 blocks the fixing ring 7, and the fixing ring 7 is fixed to the inner wall of the capsule cap 2, preventing the capsule body 1 and the capsule cap 2 from separating during the process of merging, improving the stability of the connection between the capsule body 1 and the capsule cap 2, and improving the sealing between the capsule body 1 and the capsule cap 2.

[0039] Multiple grooves 9 are provided on the outer surface of the capsule body 1, and multiple second grooves 10 are provided on the outer surface of the capsule body 1. The interior of the multiple grooves 9 and the multiple second grooves 10 are all arc-shaped. The multiple grooves 9 are respectively connected to the corresponding second grooves 10. Multiple protrusions 8 are fixedly connected to the inner wall of the capsule cap connecting ring 4. The multiple protrusions 8 are respectively slidably connected to the corresponding grooves 9, and the multiple protrusions 8 are respectively engaged with the corresponding second grooves 10.

[0040] The protrusion 8 slides on the inner wall of the groove 9, which is arc-shaped. When the protrusion 8 slides into the second groove 10, the two can be tightly engaged. This engagement usually depends on the geometric matching and interaction force between the groove 9, the second groove 10 and the protrusion 8, which helps to ensure that the protrusion 8 stays stably in the predetermined position, achieving a stable fixation and limiting, and further improving the stability of the connection between the capsule body 1 and the capsule cap 2.

[0041] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
