ABSTRACT:
An intravaginal contraceptive device formed of a ring having a central sheet of resilient impermeable material sandwiched between two layers of foam rubber. The foam rubber traps sperm and bacteria in a vaginal recess for a time sufficient to be destoyed by the normal acid pH of the vaginal secretions. The ring defines the sheet material into a cup-shape with four sides, one pair of opposing sides including a wire core inwardly bent and another pair of sides with one outwardly rounded and the other having a fork configuration. A normally closed flap valve is formed in the sheet with an attached extension for opening the flap.
