Patent attributes
A device for the pressurization and evacuation of a gas in a bottle, in order to approximate the unopened (ambient) conditions of a previous gaseous state in said bottle. Two units comprise this system, namely a charging unit and a sealing-valve unit. When the charging unit is coupled to the sealing-valve unit three functions can be performed. The first is a priming function where the bottle is partially evacuated of its ambient air and replaced with a gas from a cartridge. The second is a charging function where the primed bottle is pressurized with the same gas type or mixture from the pressurized gas cartridge. The third is an evacuating function where the charged bottle can be bled of gas to achieve the approximate ambient condition of an unopened bottle. This function is used when a bottle is overcharged and a lower pressure is desired.
