Abstract
A dispensing closure assembly is particularly configured for use on a container having carbonated or otherwise pressurized contents. The closure assembly includes a closure shell having an annular mounting collar, and an axially moveable tip positioned on the mounting collar for axial movement between opened and closed positions. Notably, the closure assembly includes an arrangement of venting projections, preferably provided on the closure shell, which provide pre-venting of gas pressure from within the container upon initial opening movement of the moveable tip. Foaming, splashing, or other undesirable discharge of liquid from within the container upon initial opening is desirably abated.
