发明名称 Flying disc
摘要 A system for converting disposable plastic or paper dinner plates into throwable flying discs. The system includes an annular foam ring. A groove is disposed on an inside surface of the annular ring. The groove receives an outer edge of the disposable plate, thereby removably securing the foam to the disposable plate. The groove has a depth which extends the groove's outer circumference to a circumference similar to an outer circumference of a standard sized, commercially available, disposable plate.
