摘要

A bottle assembly includes a container having a liquid chamber defined therein, and a vent assembly positionable substantially entirely within the liquid chamber of the container. A collar assembly generally defines a closure for the container and is releasably engageable with a neck of the container. The collar assembly and the container are configured relative to each other to enable selective configuration between a first configuration in which the vent assembly is disposed substantially entirely within the liquid chamber of the container and a second configuration in which the vent assembly is omitted from the container.
