ABSTRACT:
A dispensing fitment is temporarily retained in a conventional screw cap for application to a container as an assembly by axial ribs extending radially outward from the cylindrical sidewall of the fitment to engage the cap threads, and by thin planar fins extending radially outward from the base of each rib parallel to the end wall of the fitment and into the cap thread. An internal bead on the fitment snaps over an external groove in the container neck to secure the fitment to the container so that the fitment remains affixed to the container when the cap is removed for dispensing product from the container through a dispensing opening in the fitment end wall.
