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.

A closure member for a container, including in combination: an inner housing having means for mounting to the container, indicia means disposed in a relatively stationary manner on said inner housing and adapted to rotate with said inner housing, an outer housing rotatably mounted on and adapted to nest about said inner housing and having at least one indicator station means thereon aligned with said indicia means on said inner housing effective to pass freely the indicia thereon past said indicator station means for viewing, at least one first abutment means mounted on one of said inner or outer housings, between said inner and outer housings, and at least one second abutment means mounted to the other of said inner or outer housings opposite said one of said housings having at least one first abutment means, said second abutment means positioned to engage each of said first abutment means during rotation of said outer housing in a manner effective to stop rotation of said inner and outer housings relative to each other in one direction when said first and second abutment means are engaged, and yieldingly resist rotation of said inner and outer housings relative to each other in the opposite direction when said second abutment means is so engaged with at least one of said first abutment means, and said indicia being so disposed on said indicia means on said inner housing that said indicia are visible and aligned with said indicator station means when said first and second abutment means are engaged.
