ABSTRACT:
A container closure comprises an inner housing having means for sealably mounting to a container. A plurality of indicia are removably disposed in a relatively fixed stationary manner upon the inner housing. An outer housing is rotatably mounted to the inner housing and includes an aperture extending therethrough aligned with the indicia of the inner housing effective to pass the indicia past the aperture for viewing. One of the housings has a plurality of depressed grooves positioned upon its cylindrical walls. At least one rib on the other housing is engageable with at least one of the depressed grooves during the rotation of the outer housing and is restrained in a manner effective to stop the relative rotation of the housings in one direction, yet yieldingly resist rotation of the housings relative to each other in the opposite direction. The indicia are disposed on the inner housing such that predetermined indicia are visible through the aperture when at least one rib is engaged with at least one depressed groove.
