Description
[ technical field ] A method for producing a semiconductor device
The utility model relates to the technical field of capsules, in particular to the technical field of high-sealing hydroxypropyl methylcellulose hollow capsules.
[ background of the utility model ]
The capsule is a solid preparation prepared by filling the medicine into a hollow hard capsule or sealing the medicine into an elastic soft capsule, solves the problems of difficult entry and poor taste for a user, and really realizes that good medicines are not bitter any more; hollow capsules are more and more popular, and firstly, the capsules are slender in shape and easy to swallow, and are the most popular dosage forms for consumers; in addition, the capsule can effectively mask the unpleasant taste and smell of the contents. However, in the use process of a general hypromellose hollow capsule, the sealing effect of the capsule body and the capsule cap is poor, the phenomenon that the capsule body and the capsule cap are automatically separated usually occurs, and the capsule body and the capsule cap are easily separated by two hands when the capsule is taken, so that the powder leakage phenomenon is caused, and adverse effects are generated on users.
