  • Patent number: 5083770
    Abstract: A blood dripping fang theatrical accessory is disclosed. Controlled dripping of simulated blood from discharge ports of a bladder of the accessory may be effected by the user. The accessory has a hollow backed thin, flexible rubber-like shell simulating the appearance of an assemblage of fangs, teeth and gum. A bladder having a main body and a pair of tubular body branches is mounted on the back of the shell with its tubular body branches nested in the hollow backs of the fangs, the tubular body branches having apertures adjacent the tips of the fangs remote from the main body. Resilient material couples the bladder branches to the fangs. The accessory may be held in the mouth of the user with the fang portions projecting therefrom. The bladder portion is engageable by part of the tongue of the user which may compress the bladder to discharge simulated blood from the apertures adjacent the fang tips and interrupt or terminate such discharge by stopping further compression or by decompression of the bladder.
