AI Technical Summary
The existing empty capsules have a simple sealing structure with poor sealing effect. The connection between the capsule cap and the capsule body is easy to detach, which can lead to drug leakage and affect storage and efficacy.
The design incorporates a combination of threaded convex surface, limiting ring edge, anti-detachment barb foot, capsule cap, threaded concave surface, and anti-detachment inner ring groove. The threaded connection and limiting structure stabilize the connection between the capsule cap and capsule body, preventing detachment, and the anti-detachment barb foot and inner ring groove further enhance the sealing performance.
This design achieves stability at the connection between the capsule cap and the capsule body, improves sealing, prevents drug leakage, and ensures stable storage and efficacy of the drug.
