A safety lid for flanged containers including a base cap dimensioned to fit upon the upper end of the container and having a central aperture therethrough. An upper cap is rotatable mounted on the base cap and includes a downwardly extending flange having zones of depressions or relief formed therein at circumferentially spaced points. The base cap carries a pair of flexible, resilient locking fingers which project substantially parallel to the sides of the container upon which the cap is utilized. Each locking finger carries at its lower end, a locking toe adapted to engage a flange carried around the outer periphery of the upper end of the container upon which the cap is utilized. Each locking finger carries an upwardly extending portion which can be biased by digital manipulation into the relieved zones in the peripheral flange carried by the upper cap when the upper cap is rotated to a position with respect to the base cap such that the relieved zones are aligned with the locking fingers. Pivotation of the locking fingers into the zones of relief by pressing the upwardly extending portions into such zones biases the locking toes radially outwardly with respect to a container upon which the cap is mounted so that the entire cap may be removed from the container.
