Projection device of confetti sets off by the ejection of the plug of a bottle of effervescent drink

摘要

The device (1) has a confetti charge (8) placed on a plate (17), and propulsion mechanism (14) with a compression spring (23) maintained in compression and released positions. A triggering mechanism (15a) uses a counterweight (21) moved along an axis (16). A fixation unit has a cover (5) fixed on the top of a stopper (2) to integrate the device to the stopper such that the triggering mechanism activates the propulsion mechanism by releasing the spring for propulsion of the plate that propels the charge, when the closure is ejected from a effervescent beverage bottle (3) by gas pressure.
