Abstract
A retainer is provided for a face piece that has a generally triangular face shaped rim for forming a seal over user's face when the face piece is worn. The retainer is made from a stiff material and has a rim that conforms to the rim of the face piece, and is shaped to provide a loose frictional fit over the face piece. The retainer helps protect the face piece during shipping, storage, and when otherwise not in use, and can help correct minor deformation in a face piece.
