A 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 an invertible fold between these two sections so as to enable the closure body to be either nested or extended. 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 frustoconical section includes a thicker wall portion, described as a memory band portion, for enabling the closure body to maintain a selected orientation upon deflection into the selected orientation in order to provide directional discharge of the container contents. |
