Vulvar Deodorant System," (U.S. patent 3,948,257 - April 6, 1976)
Companies have devised many ways to deodorize a woman's vulva and vagina, including sprays, douches, pad powder, washes and deodorant pads and tampons. The patent below, for a device probably never manufactured, describes a little weight designed to both deodorize and remind a woman to remove her tampon
(the "flower," number 23 on the patent drawing below; flowers have a long association with menstruation - see it used in ad for a menstrual cup - although I'm sure that was unknown to the inventor).
Here the writer explains why he - yes, a man devised this, just as men seem to invent most of women's "hygienic" devices, start museums of menstruation, etc. - invented the "system."
