    • A dispensing closure is equipped with child resistant means of securing same on a container and provides for concentric primary orifice for dispensing that is capable of enlarging its size to a secondary orifice for easy rinsing of the container package or complete product removal as desired. A pull ring is secured to the closure top wall surrounding the primary orifice and an annular line of weakening is formed in the top wall encircling the ring pull and defining an enlarged area. The ring pull may be used to manually remove the material of the enlarged area portion and provide the enlarged orifice. The removable material can provide for marketing promotions of the package. The preferred closure is illustrated as a snap hinged cover cap and child resistant dispensing closure in which the main closure includes a skirt wall and radially-spaced flexible outer wall that is deformable to open the cover cap which provides a further child resistant feature to the package.
