Abstract
A vented closure assembly for a container, the container including a raised outlet defining a dispensing opening, includes a closure body having a nestable and extendable spout formed with a generally cylindrical section, a frustoconical section, and a transition region, including an invertible fold, located between these two sections. The generally cylindrical section defines an outlet opening and a threaded closing cap is assembled to the generally cylindrical section for closing off the outlet opening. A retainer is used for connecting the closure body to the raised outlet wall and the spout includes a thicker wall portion for enabling the closure body to maintain a selected orientation. A plurality of venting ears are used to help provide the venting capability.
