Description

Technical Field

[0001] This invention belongs to the field of empty capsule products, and in particular relates to a capsule with a multi-cavity structure. Background Technology

[0002] Current capsule packaging involves directly encapsulating the contents within the capsule shell. Capsules used to hold medications are generally powders or granules that irritate the esophagus and stomach lining, or medications with unpleasant taste, high volatility, easy breakdown by saliva in the mouth, or easy inhalation into the trachea. Encapsulating these medications protects their efficacy and also safeguards the digestive and respiratory systems. However, most common capsule products have a single-chamber structure, which, with the advancement of medical technology, can no longer meet specific usage needs. For example, for medications requiring simultaneous oral administration of multiple drug components, current technology often achieves this by taking multiple capsules at once, increasing user discomfort and reluctance. However, placing multiple drug components directly within a single capsule can lead to some components mixing and, after long-term storage, resulting in decreased efficacy or other adverse effects on the body. Furthermore, in disease treatment or prevention, medications have different applications and needs, such as rapid-acting, long-acting, and buffering effects, sometimes requiring a specific dissolution order to achieve a particular therapeutic effect. Therefore, it is necessary to optimize and improve the existing capsule structure. Summary of the Invention

[0003] In view of this, the present invention aims to overcome the deficiencies in the prior art and propose a capsule with a multi-cavity structure.

[0004] To achieve the above objectives, the technical solution created by this invention is implemented as follows:

[0005] A capsule with a multi-cavity structure includes an outer capsule structure and an inner capsule structure inside the outer capsule structure. The outer capsule structure includes an outer capsule body and an outer capsule cap fastened to the outer capsule body. The inner capsule structure includes an inner capsule body and an inner capsule cap fastened to the inner capsule body. An inner capsule cavity is formed between the inner capsule body and the inner capsule cap. An outer capsule body-side cavity is formed between the inner capsule body and the outer capsule body. An outer capsule cap-side cavity is formed between the inner capsule cap and the outer capsule cap. The wall thickness of the outer capsule cap is greater than the wall thickness of the outer capsule body. A mating part is provided on the outer wall of the opening end of the inner capsule cap. A limiting section is provided on the inner wall of the outer capsule cap corresponding to the mating part. A positioning platform is provided on the side of the limiting section away from the opening end of the outer capsule cap. The outer wall of the mating part mates with the inner wall of the limiting section. The side of the mating section facing the opening end of the inner capsule cap abuts against the end face of the opening end of the outer capsule body. The side of the mating section opposite to the opening end of the inner capsule cap abuts against the positioning platform. Several raised rings are provided on the outer wall of the opening end of the outer capsule body. A groove matching each raised ring is provided on the inner wall of the opening end of the outer capsule cap.

[0006] Furthermore, the inner capsule and the outer capsule are arranged coaxially.

[0007] Furthermore, the inner cap and the outer cap are arranged coaxially.

[0008] Furthermore, the opening end of the outer cap is provided with several slits.

[0009] Furthermore, each slit has 3-5 slits evenly distributed along the circumference of the outer cap.

[0010] Furthermore, the protruding rings are provided in 3-4 rows at intervals along the axial direction of the outer bladder.

[0011] Furthermore, the volume of the inner cyst is greater than the volume of the outer cavity on the cyst body side, the volume of the inner cyst is greater than the volume of the outer cavity on the cyst cap side, and the sum of the volumes of the outer cavity on the cyst body side and the outer cavity on the cyst cap side is greater than the volume of the inner cyst.

[0012] Furthermore, the outer wall of the opening end of the outer cap is provided with a conical guide surface.

[0013] Furthermore, the outer cap is arranged coaxially with the outer capsule body, and the inner cap is arranged coaxially with the inner capsule body.

[0014] Compared with existing technologies, the present invention has the following advantages:

[0015] This invention features a rationally designed structure. By incorporating an inner capsule structure within the outer capsule structure, and further dividing the outer capsule into three drug-storing cavities—an inner capsule cavity, a capsule body-side outer cavity, and a capsule cap-side outer cavity—it allows for the placement of three drug components within the capsule. This ensures that the components do not come into contact during transportation and storage, thus maintaining stable efficacy. Furthermore, upon administration, the outer capsule body and cap dissolve first, releasing the drug from the capsule body-side outer cavity, followed by the drug from the capsule cap-side outer cavity, and finally the drug from the inner capsule cavity. This controllable drug release sequence ensures the drug exerts its effects in a predetermined order, resulting in better therapeutic outcomes. Attached Figure Description

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0026] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0027] The invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] A capsule with a multi-cavity structure, such as Figures 1 to 7As shown, the structure includes an outer capsule and an inner capsule within it. The outer capsule includes an outer capsule body 1 and an outer capsule cap 2 attached to the outer capsule body. The inner capsule includes an inner capsule body 3 and an inner capsule cap 4 attached to the inner capsule body. An inner capsule cavity 5 is formed between the inner capsule body and the inner capsule cap. A capsule body-side outer cavity 6 is formed between the inner capsule body and the outer capsule body. A capsule cap-side outer cavity 7 is formed between the inner capsule cap and the outer capsule cap. The wall thickness of the outer capsule cap is greater than that of the outer capsule body. During administration, the outer capsule body dissolves faster than the outer capsule cap, resulting in the drug in the capsule body-side outer cavity being released before the drug in the capsule cap-side outer cavity, while the drug in the inner capsule cavity is released last. To ensure that the outer capsule cap is smoothly attached to the outer capsule body, several slits 13 can be provided at the open end of the outer capsule cap. For example, 3-5 slits are evenly distributed along the circumference of the outer capsule cap.

[0029] The outer wall of the inner cap opening has a mating part 14, and the inner wall of the outer cap has a limiting section 8 corresponding to the mating part. A positioning platform 9 is provided on the side of the limiting section away from the outer cap opening. The outer wall of the mating part mates with the inner wall of the limiting section. The mating section abuts against the end face of the outer cap opening on the side facing the inner cap opening, and abuts against the positioning platform on the side of the mating section opposite to the inner cap opening. The outer wall of the outer cap opening has several raised rings 10, and the inner wall of the outer cap opening has grooves 11 that match each of the raised rings. Typically, 3-4 raised rings are spaced apart along the axial direction of the outer cap.

[0030] This invention eliminates the need for an internal support structure. By utilizing the mating portion on the inner capsule cap to simultaneously limit the movement of the outer capsule cap and outer capsule body, the stability of the inner capsule cap structure is ensured. The relative positions of the inner capsule cap, outer capsule cap, and outer capsule body are fixed, and the inner capsule body on the inner capsule cap can be stably held within the outer capsule structure. This simplifies the structure and facilitates production. The volume of the inner capsule cavity is larger than the volume of the outer cavity on the capsule body side, and the volume of the inner capsule cavity is larger than the volume of the outer cavity on the capsule cap side. Furthermore, the sum of the volumes of the outer cavity on the capsule body side and the outer cavity on the capsule cap side is greater than the volume of the inner capsule cavity. The capsule interior is divided into three drug-storing cavities: the inner capsule cavity, the outer cavity on the capsule body side, and the outer cavity on the capsule cap side. This allows for the placement of three drug components within the capsule, ensuring that the drug components do not come into contact during transportation and storage, thus ensuring stable efficacy.

[0031] To ensure smooth swallowing, a conical guide surface 12 is provided on the outer wall of the opening end of the outer capsule cap to reduce the protrusion height at the junction of the outer capsule cap and the outer capsule body. Furthermore, in the capsule product provided by this invention, the inner capsule body and the outer capsule body are arranged coaxially, as are the inner capsule cap and the outer capsule cap. The outer capsule cap and the outer capsule body are arranged coaxially, and the inner capsule cap and the inner capsule body are arranged coaxially.

[0032] This invention features a rationally designed structure. By incorporating an inner capsule structure within the outer capsule structure, and further dividing the outer capsule into three drug-storing cavities—an inner capsule cavity, a capsule body-side outer cavity, and a capsule cap-side outer cavity—it allows for the placement of three drug components within the capsule. This ensures that the components do not come into contact during transportation and storage, thus maintaining stable efficacy. Furthermore, upon administration, the outer capsule body and cap dissolve first, releasing the drug from the capsule body-side outer cavity, followed by the drug from the capsule cap-side outer cavity, and finally the drug from the inner capsule cavity. This controllable drug release sequence ensures the drug exerts its effects in a predetermined order, resulting in better therapeutic outcomes.

[0033] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
