Abstract
Description
Technical Field
[0001] This utility model relates to a hollow capsule, particularly a biodegradable hollow capsule. Background Technology
[0002] Empty capsules consist of a cap and a body, made from pharmaceutical-grade gelatin and excipients. They are primarily used to contain solid and liquid medications, such as homemade powders, health supplements, and pharmaceuticals. This solves the problem of unpleasant taste and difficulty in swallowing, truly making good medicine palatable. Currently, most empty capsules are made of gelatin. To ensure structural stability and resistance to deformation, the capsule walls are generally made relatively thick. However, while increased wall thickness ensures structural stability and resistance to deformation, it also increases the degradation rate of the empty capsule. Therefore, existing empty capsules suffer from a relatively low degradation rate. Utility Model Content
[0003] The purpose of this invention is to provide an easily degradable hollow capsule. This invention has the advantage of a high degradation rate.
[0004] The technical solution of this utility model: an easily degradable hollow capsule, comprising a capsule body support ring, the outer surface of which is provided with external threads; a capsule body support block is provided above the capsule body support ring; a spiral capsule body support strip is provided between the capsule body support block and the capsule body support ring, and a capsule body membrane is adhered between the outer surfaces of the capsule body support strip, the capsule body support ring, and the capsule body support block; a capsule cap support ring is threadedly connected to the capsule body support ring, and the inner sidewall of the capsule cap support ring is provided with internal threads that mate with the external threads; a spiral capsule cap support strip is provided on the top surface of the capsule cap support ring, and a capsule cap support block is connected to the end of the capsule cap support strip; glue A capsule cap membrane is attached to the outer surfaces of the capsule cap support block, capsule cap support strip, and capsule cap support ring. The capsule body support ring and capsule cap support ring, connected by threads, allow the capsule body and capsule cap to be easily and stably assembled together, facilitating assembly. By setting the capsule body support block and the spiral capsule body support strip and capsule body support ring to form the capsule body body, and then combining it with the capsule body membrane to form the entire capsule body, the structural stability of the capsule body is ensured while reducing the thickness requirement of the capsule body membrane. This minimizes the overall mass of the capsule body and accelerates the subsequent digestion and absorption of the capsule body in the stomach, thereby accelerating the degradation rate of the capsule body in the stomach.
[0005] In the aforementioned biodegradable hollow capsule, a limiting groove is provided on the inner wall of the capsule cap support ring, and the depth of the limiting groove is greater than the height of the capsule body support ring; the internal thread is provided on the inner wall of the limiting groove; the limiting groove can limit the depth of the threaded connection between the capsule cap support ring and the capsule body support ring, thereby avoiding the phenomenon of the capsule cap and capsule body being over-connected, and ensuring the stability of assembly.
[0006] In the aforementioned biodegradable hollow capsule, both the capsule body support block and the capsule cap support block are hemispherical. By setting both the capsule body support block and the capsule cap support block to be hemispherical, both ends of the assembled hollow capsule are spherical, thereby improving the overall deformation resistance of the hollow capsule.
[0007] In the aforementioned biodegradable hollow capsule, the capsule cap support ring is provided with an exhaust channel, which is located on one side of the limiting groove. The exhaust channel facilitates the discharge of air between the capsule cap and the capsule body during assembly, avoiding excessive internal air pressure and ensuring the stability of assembly and use.
[0008] In the aforementioned biodegradable hollow capsules, the capsule body support ring, capsule body support block, capsule body support strip, capsule cap support ring, capsule cap support strip, and capsule cap support block are all made of gelatin.
[0009] Compared with existing technologies, this invention improves upon conventional hollow capsules by incorporating threaded capsule body support rings and capsule cap support rings. These threaded rings facilitate convenient and stable assembly of the capsule body and capsule cap. Furthermore, by using capsule body support blocks and spiral capsule body support strips to form the capsule body main body along with the capsule body support rings, and then combining this with the capsule body membrane to form the entire capsule body, the structural stability of the capsule body is ensured while reducing the thickness requirements of the capsule body membrane. This minimizes the overall mass of the capsule body and accelerates subsequent digestion and absorption in the stomach, thus speeding up the degradation rate of the capsule body in the stomach. Similarly, by using capsule cap support rings, spiral capsule cap support strips, and capsule cap support blocks to form the main structure of the capsule cap, and then adding the capsule cap membrane, the overall mass of the capsule cap is minimized while accelerating its degradation and absorption. Furthermore, this invention also features a limiting groove on the inner wall of the capsule cap support ring. This limiting groove limits the depth of the threaded connection between the capsule cap support ring and the capsule body support ring, preventing over-connection and ensuring assembly stability. By designing both the capsule body support block and the capsule cap support block as hemispherical, the assembled hollow capsule has spherical ends, improving its overall deformation resistance. Additionally, the capsule cap support ring includes an exhaust channel, facilitating the removal of air between the capsule cap and capsule body during assembly, preventing excessive internal pressure and ensuring stability during assembly and use. Therefore, this invention not only improves the degradation rate but also offers advantages such as easy assembly, high structural stability, and high deformation resistance.

Detailed Implementation
[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.
[0014] Example. Easily biodegradable empty capsules, configured as follows: Figure 1 and 2As shown, the capsule includes a capsule body support ring 1 with external threads on its outer surface; a capsule body support block 2 is positioned above the capsule body support ring 1; a spiral capsule body support strip 3 is positioned between the capsule body support block 2 and the capsule body support ring 1; a capsule body membrane 4 is attached between the outer surfaces of the capsule body support strip 3, the capsule body support ring 1, and the capsule body support block 2; a capsule cap support ring 5 is threaded onto the capsule body support ring 1, and an internal thread that mates with the external threads is positioned on the inner sidewall of the capsule cap support ring 5; a spiral capsule cap support strip 6 is positioned on the top surface of the capsule cap support ring 5, and a capsule cap support block 7 is connected to the end of the capsule cap support strip 6; a capsule cap membrane 8 is attached between the outer surfaces of the capsule cap support block 7, the capsule cap support strip 6, and the capsule cap support ring 5.
[0015] The inner wall of the capsule cap support ring 5 is provided with a limiting groove 9, the depth of which is greater than the height of the capsule body support ring 1; the internal thread is provided on the inner wall of the limiting groove 9; the capsule body support block 2 and the capsule cap support block 7 are both hemispherical; the capsule cap support ring 5 is provided with an exhaust channel 10, which is located on one side of the limiting groove 9; the capsule body support ring 1, capsule body support block 2, capsule body support strip 3, capsule cap support ring 5, capsule cap support strip 6 and capsule cap support block 7 are all made of gelatin.
[0016] Working principle: During assembly, simply align the capsule body support ring 1 with the limiting groove 9 on the capsule cap support ring 5. The external thread on the outer side of the capsule body support ring 1 engages with the internal thread on the inner wall of the limiting groove 9, thus threading the capsule body support ring 1 and the capsule cap support ring 5 together. This allows the capsule body, composed of the capsule body support ring 1, capsule body support block 2, capsule body support strip 3, and capsule body membrane 4, to be assembled with the capsule cap, composed of the capsule cap support ring 5, capsule cap support strip 6, capsule cap support block 7, and capsule cap membrane 8. During the filling process, the internal gas is discharged through the exhaust channel 10, ensuring the stable assembly of the entire hollow capsule. Because the main structure of the capsule body and capsule cap consists of capsule body support ring 1, capsule body support block 2, capsule body support strip 3, capsule cap support ring 5, capsule cap support strip 6 and capsule cap support block 7, and its outer layer is only covered with capsule body membrane 4 and capsule cap membrane 8, when the hollow capsule enters the stomach and comes into contact with gastric juice, the capsule body membrane 4 and capsule cap membrane 8 will be rapidly degraded by gastric juice, releasing the internal drug and increasing the overall degradation rate.
