The capsule is designed to ensure proper mixing of the flowable substances during delivery, both with each other and with the carrier gas that entrains them and delivers them t o a predetermined deposition site. The capsule is further designed to ensure complete emptying of the flowable substances from the capsule so that virtually the entire dose is deliverable to the predetermined deposition site. |
