<p>Between the base /5/ and the foil packing /4/ of the 'pilferproof' type in cylindrical shape /6/ with internal thread /7/, a microswitch sensor 1 was located, connected to a microprocessor /7/, playing different tunes, powered by a microbattery /3/. Unscrewing the cap results in reducing pressure of the foil packing upon the microswitch /1/ and starting the microprocessor playing, for example, popular wedding tunes.</p> |
