BOTTLE SREW CAP WITH AUDIBLE MESSAGE GENERATOR

摘要

The sensor microswitch (1), coupled with the microprocessor (2) playing occasional melodies, supplied with the microbattery (3), is located between the bottom (5) and the film gasket (4) of the "pilferproof" type screw cap which has a form of a cylinder (6) with the internal thread (7). Unscrewing of the screw cap reduces the pressure affecting the microswitch (1) through the film gasket and switches on the microprocessor, playing popular drinking songs.
