DUAL CONFIGURATION BOTTLE ASSEMBLY

摘要

A bottle assembly includes a container and a vent assembly positionable at least in part of a rim of the container. A collar assembly generally defines a closure for the container and is releasably engaged with a neck of the container. The collar assembly and the vent assembly are configured relative to one another to permit selective configuration between a first configuration and a second configuration. In the first configuration, the collar assembly urges the vent assembly onto the rim of the container such that at least a majority of a cross-section of a lateral vent of the vent assembly is disposed below the rim. In the second configuration, in which the vent assembly is omitted from the bottle assembly, the collar assembly substantially sealingly engages the rim of the container.
