They are mainly used to contain solid drugs or other drugs that are easily destroyed in the stomach. Enteric-coated hollow capsules are cylindrical, and are hard and elastic hollow capsules with a cap and a body. Existing enteric-coated hollow capsules have a simple sealing structure and poor sealing effect. The connection between the cap and the body is easy to separate and leak the contents of the drug, which is not conducive to storing the enteric-coated hollow capsules and ensuring the efficacy of the drug.
