Abstract
Description
Technical Field
[0001] This utility model relates to the field of capsule technology, and in particular to an enteric-coated empty capsule. Background Technology
[0002] Enteric-coated empty capsules are made of capsule gelatin and suitable enteric materials. They are divided into ordinary enteric-coated capsules and colonic enteric-coated capsules. They are mainly used to contain solid drugs or other medications that are easily destroyed in the stomach. They solve the problem of difficult to swallow and poor taste for users, truly making good medicine no longer bitter. Empty capsules are becoming increasingly popular. First, the capsules are long and thin, making them easy to swallow. By filling the capsules with tasteless or slightly fragrant substances, the odor of the drug itself is masked, reducing the patient's resistance to taking the medication. Because the capsule walls are thick and not dissolved by gastric juice, they can effectively protect the drug from the erosion of gastric acid, thereby reducing the irritation of the gastric contents to the mucosa.
[0003] Enteric-coated empty capsules generally require water to be swallowed. During swallowing, the capsules are easily squeezed. However, the connection structure of existing enteric-coated empty capsules is not stable enough. After being squeezed, gaps are easily formed, allowing stomach acid to enter. Furthermore, the medication inside the capsules tends to accumulate, affecting the drug's effectiveness. Therefore, there is a need for an enteric-coated empty capsule. 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 an enteric-coated empty capsule that can solve the problems of unstable structure at the connection point of the enteric-coated empty capsule, which easily produces certain gaps after being squeezed, allowing gastric acid to enter, and the drugs inside the enteric-coated empty capsule easily accumulating together, affecting the efficacy of the drug.

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.
[0025] 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.
[0026] Please see Figure 1-6This utility model provides a technical solution: an enteric-coated empty capsule, including a first capsule shell A1, a second capsule shell B2 disposed on one side of the first capsule shell A1, a plurality of first anti-slip ridges A3 formed on the outer surface of the first capsule shell A1, a plurality of second anti-slip ridges B4 formed on the outer surface of the second capsule shell B2, the first anti-slip ridges A3 and the second anti-slip ridges B4 having the same shape and number, a sealing connecting shell 5 fixedly connected inside the first capsule shell A1, an external thread 6 formed on the outer surface of the sealing connecting shell 5, a convex ring 7 fixedly sleeved on the outer surface of the sealing connecting shell 5, an internal thread 8 formed on the inner wall of the second capsule shell B2, a groove 9 formed on the inner wall of the second capsule shell B2, the sealing connecting shell 5 and the second capsule shell B2 being internally threadedly connected, the external thread 6 being adapted to the internal thread 8, the convex ring 7 being slidably connected inside the groove 9, the convex ring 7 being adapted to the shape of the groove 9.
[0027] Furthermore, the first capsule shell A1 has an internal cavity A12 for containing the drug, and the second capsule shell B2 has an internal cavity B11 for containing the drug. The internal cavity B11 is connected to the internal cavity A12. The inner wall of the first capsule shell A1 is fixedly connected to a plurality of upper cavity partitions 13 and a plurality of lower cavity partitions 14. The number of upper cavity partitions 13 and lower cavity partitions 14 are the same and they are staggered. Both upper cavity partitions 13 and lower cavity partitions 14 are located inside the internal cavity A12. The internal cavity of the second capsule shell B2 is fixedly connected to a partition 10, which is located inside the internal cavity B11. The inner wall surface of the first capsule shell A1 is provided with a first sugar coating film A15, and the inner wall surface of the second capsule shell B2 is provided with a second sugar coating film B16.
[0028] Furthermore, the sealing connection shell 5 provided on the first capsule shell A1 is threaded onto the inner wall of the second capsule shell B2 by the adaptation of the external thread 6 and the internal thread 8. The convex ring 7 on the sealing connection shell 5 slides into the interior of the second capsule shell B2 and then into the groove 9 provided on the second capsule shell B2. The convex ring 7 is frustoconical in shape and matches the shape of the groove 9. It can be inserted into the interior of the groove 9 and limit the first capsule shell A1 and the second capsule shell B2. Since the sealing connection shell 5 is threaded into the interior of the second capsule shell B2, it has a tighter connection strength. By inserting the convex ring 7 into the interior of the groove 9, loosening can be avoided, and the sealing performance of the capsule can be strengthened. The upper chamber partition 13, the lower chamber partition 14 and the first sugar coating film A15 provided inside the first capsule shell A1 and the second capsule shell B2 can separate the internal chambers of the first capsule shell A1 and the second capsule shell B2, preventing the drugs from accumulating together.
[0029] Furthermore, the connection strength between the first capsule shell A1 and the second capsule shell B2 is strengthened by threading the sealing connection shell 5 inside the second capsule shell B2. The connection between the first capsule shell A1 and the second capsule shell B2 is made tighter by inserting the convex ring 7 into the groove 9, enhancing the sealing performance and preventing loosening between the first capsule shell A1 and the second capsule shell B2. The upper chamber partition 13, the lower chamber partition 14, and the first sugar coating film A15 provided inside the first capsule shell A1 and the second capsule shell B2 can further connect the first capsule shell A1 and the second capsule shell B2. The internal chambers of the outer shell B2 are separated to prevent the drugs from piling up and to enhance drug absorption efficiency. The first sugar coating film A15 and the second sugar coating film B16 can improve the taste of the capsule. The first anti-slip ridge A3 and the second anti-slip ridge B4 on the first capsule shell A1 and the second capsule shell B2 make the capsule less likely to fall off when handled, increasing its practicality. The above structural design solves the problems of insufficient structural stability at the connection of enteric-coated empty capsules, which can easily create gaps after being squeezed, allowing gastric acid to enter, and the drugs inside enteric-coated empty capsules tend to pile up, affecting the efficacy of the drug.
