Abstract
A child resistant dispensing container end closure is disclosed which includes a one-piece cap and a one-piece lid removably secured to the cap. The cap includes several openings for dispensing the contents of the container, and the lid covers the openings to prevent dispensing when the lid is in place on the cap. The cap includes an axially recessed center portion, and an annular safety wall encircles the recessed center portion. The lid is frictionally secured in the recess, and an outer peripheral wall and outer peripheral corner of the lid closely confront the safety wall of the cap about their entire annular extent. This limits access to the peripheral wall and peripheral corner of the lid so that the lid cannot be grasped and removed by a child.
