Package for carbonated drinks has chambers that are not in fluid communication when openings on piece and on fixed platform do not coincide, thereby preserving pressure in one chamber

摘要

The package is divided into two chambers and has a cork which, when moved, deviates a piece having openings. When the openings on the piece coincide with the openings of a fixed platform, then fluid communication between the chambers is established. Otherwise, the chambers are insulated from each other and pressure in one chamber is preserved.
