Abstract
Abstract The invention is generally accomplished by forming a three-dimensionally shaped, externally worn feminine protection device (10) which has been mechanically shaped by folding, molding or other forming techniques in such a way that it has a raised portion (34) located within the back one-half to two-thirds of the device that functions to cause the pad to readily fit to and generally align itself within the inverted V-shaped regions of the woman's lower abdominal region, vulva, perineum and the anterior portion between the buttocks. The forward portion (30) of the device of the invention generally is flattened in use to cover externally the area of the pubic mons and the area exterior of the clitoris. The back portion (32) of the device is formed in a peak (34) like shape which readily adjusts to and molds to the inverted V-shape of the rear portion of the labia, the perineum and the forward portion of the area between the buttocks.
