Abstract
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. This solves the problems of difficult swallowing and poor taste for users. The capsules are long and thin, making them easy to swallow and a popular dosage form among consumers. 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 dealing with transportation bumps, due to the limited friction between the protrusions and grooves, the two capsule shell sections of the cap and body are prone to direct separation when subjected to strong vibrations. The separation of the cap and body may cause the drug to be destroyed in the stomach, thus affecting its stability and efficacy. Therefore, this utility model proposes a new solution. Utility Model Content
[0004] The purpose of this invention is to solve at least 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 transportation bumps, the limited friction between the protrusions and grooves causes the cap and body sections of the capsule shell to easily separate directly under strong vibrations. The separation of the cap and body may lead to the destruction of the drug in the stomach, thereby affecting its stability and efficacy.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a plant-based hollow capsule, comprising a capsule body with a capsule cap snapped onto the capsule body;
[0006] The snap-fit assembly is disposed on the capsule body and includes four second limiting plates, which are fixedly connected to the capsule body. An annular groove is formed on the surface of the capsule body.
[0007] The annular groove is fixedly connected with four first limiting plates, and the inner wall of the capsule cap is fixedly connected with four third limiting plates. All four third limiting plates are engaged with the first limiting plates.
[0008] Preferably, an outer fixing ring is fixedly connected to the surface of the capsule body, and an inner fixing ring is fixedly connected to the inner wall of the capsule cap. The inner fixing ring is engaged with four second limiting plates.
[0009] Preferably, a plurality of first protrusions are fixedly connected to the surface of the capsule body, and a plurality of second protrusions are fixedly connected to the surface of the capsule cap;
[0010] The multiple first bumps and multiple second bumps are all spherical.
[0011] Preferably, both the capsule body and the capsule cap are made of fibers extracted from plant wood pulp.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This plant-based hollow capsule uses a first and third limiting plate to secure the capsule body and cap. The primary function of this locking mechanism is to ensure structural stability and prevent drug spillage. Specifically, this locking design prevents the capsule cap from detaching due to vibration, effectively avoiding drug loss and improving product reliability. Attached Figure Description

[0021] 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.
[0022] 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.
[0023] 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 terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.
[0024] 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.
[0025] Please see Figure 1-5 This utility model provides a technical solution: a plant hollow capsule, including a capsule body 1, a capsule cap 2 snapped onto the capsule body 1, a snapping assembly, the snapping assembly being disposed on the capsule body 1, the snapping assembly including four second limiting plates 7, the four second limiting plates 7 being fixedly connected to the capsule body 1, an annular groove 5 being formed on the surface of the capsule body 1, four first limiting plates 6 being fixedly connected inside the annular groove 5, and four third limiting plates 9 being fixedly connected to the inner wall of the capsule cap 2, all four third limiting plates 9 being snapped onto the first limiting plates 6.
[0026] The snap-fitting of the first limiting plate 6 and the third limiting plate 9 facilitates the positioning of the capsule body 1 and the capsule cap 2. The main function of this snap-fitting design is to ensure structural stability and prevent drug spillage. Specifically, this snap-fitting design prevents the capsule cap from falling off due to vibration, effectively avoiding drug spillage and improving product reliability.
[0027] An outer fixing ring 4 is fixedly connected to the surface of the capsule body 1, and an inner fixing ring 10 is fixedly connected to the inner wall of the capsule cap 2. The inner fixing ring 10 is engaged with four second limiting plates 7.
[0028] The engagement between the inner fixing ring 10 and the second limiting plate 7 facilitates the sealing of the contact surfaces of the capsule body 1 and the capsule cap 2. This enhanced sealing prevents the drug from being digested in the stomach, ensuring that the drug is fully released and absorbed in the intestines, thus maintaining its efficacy. The design of the inner fixing ring 10 and the outer fixing ring 4 makes the connection between the capsule body 1 and the capsule cap 2 more secure, preventing accidental separation during transportation or use, thereby protecting the drug from loss or contamination. At the same time, the design of the outer fixing ring 4 and the inner fixing ring 10 can improve the bending resistance and strength of the capsule body 1 and the capsule cap 2, preventing deformation of the capsule during transportation.
[0029] Multiple first protrusions 3 are fixedly connected to the surface of the capsule body 1, and multiple second protrusions 8 are fixedly connected to the surface of the capsule cap 2. The multiple first protrusions 3 and the multiple second protrusions 8 are all spherical.
[0030] The first protrusion 3 and the second protrusion 8 help increase the contact area between the capsule body and the external environment, thereby improving its stability during storage and transportation and reducing the risk of capsule deformation or breakage caused by external factors (such as humidity, temperature, etc.). The spherical protrusion design of the first protrusion 3 and the second protrusion 8 makes the capsule easier to slide when swallowing, reducing friction with the esophagus, thereby improving the patient's experience, especially for people with difficulty swallowing.
[0031] Both capsule body 1 and capsule cap 2 are made of fibers extracted from plant wood pulp.
[0032] Certain soluble components in plant-based empty capsules, such as cellulose and gelatin, can promote gastrointestinal motility, relieve constipation, improve the taste of the medication, and enhance its stability.
[0033] 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.
