Kissing Shield (US5727565)

The mysophobe in everyone can cringe at the idea of catching an illness from a well-meaning kiss. Enter the kissing shield, which if handled properly, "will help people who want to do whatever they can while kissing to practice 'preventive medicine,'" according to the 1995 patent. A flexible thin membrane is stretched over a heart-shaped frame, which folds for easy storage and attaches to a handle for quick use. According to the patent, the kissing shield could even "be used especially by a politician who kisses babies."
