发明名称 Retainer and method of making
摘要 A Hawley-type retainer is formed with a reinforcing design carrier laminated within a colored plastic retainer body and partially surrounded by a clear or colored plastic mound, which is laminated within the colored plastic body. The clear or colored and highly visible design on the carrier adds interest and identification to the retainer, promoting its use and location and preventing loss or accidental destruction. The invention is attractive to children so they wear the retainer often.
