ABSTRACT:
A female contraceptive, cervical cover, including a dome-like main portion which is shaped to cover the cervix, long extending lips which form a one-way valve to permit waste material to flow out of the cervix and an outwardly biased collar which holds the cover securely to the walls of the vagina surrounding the cervix, without exerting any substantial pressure on the cervix.
