A device that assists with equalizing air pressure within a bottle with the atmospheric air pressure as liquid is being poured from the bottle and includes one or more relatively short air tubes. The air tubes are situated with an upper inlet rim of the air tubes located flush with or relatively near the bottle rim. Whether an insert or integrated into the manufacture of a container, the one or more air tubes that extend partially into the container allow air to pass into the container as the liquid exits the container. The pressure equalizer not only mi...
1. A bottle insert for substantially equalizing atmospheric air pressure with air pressure within a bottle when pouring a liquid from the bottle, the bottle insert comprising: an air inlet channel adapted for contacting at least a portion of an interior bottleneck wall and extending circumferentially around at least a portion of the interior bottleneck wall, the air inlet channel including a perimeter member contacting at least a portion of the interior bottleneck wall, the air inlet channel further including a distal base and an interior channel wall lo...
