A child resistant closure comprising an outer shell having a base wall and a peripheral skirt and an inner shell having a base wall and a peripheral skirt telescoped within the outer shell. The inner surface of the base wall of the outer shell and the outer surface of the base wall of the inner shell have circumferentially spaced radial projections which are adapted to interengage upon relative axial movement between the shells. The top wall of the inner shell includes indentations or grooves between the projections which are at a small acute angle with respect to the plane of the top wall of the inner shell. The inner surface of the outer shell has at least one inclined indentation or surface which extends radially and is also at an acute angle to the plane of the base wall of the outer shell. When the outer shell is tilted in the direction of the inclined surface, the lugs projecting from the area of the inclined surface of the base wall of the outer shell engage the grooves in the outer surface of the base wall of the inner shell allowing the inner shell to be unscrewed from the container on which the closure is provided. The closure can be also operated by moving the outer shell axially toward the inner shell to engage the projections on the outer shell and inner shell.
