Abstract
The present invention includes a device for dispensing liquids that includes a main body having a mechanism for attaching to and sealing a liquid container, a vent on the main body for transferring air into the liquid container, and a mechanism for restricting air transferred through the vent to a threshold volume effective to substantially equalize pressure within the liquid container while preventing a transfer of vapor from the container.
