ABSTRACT:
A preservative comprises a conventional condom rolled about an applicator ring defining member(s) comprised of resilient material. The ring may be formed by cutting an elongated elastic member to length and elastically deforming the member into an annular shape. Alternatively, the ring may be composed of a plurality of C-shaped ring sectors. In either case, the ring will fall off the condom upon the latter being unrolled.
