Reminder closure

A closure for a container, said closure comprising:

• an inner housing having a cylindrical wall means for sealably mounting to said container and a plurality of indicia means disposed in a relatively fixed stationary manner thereupon,
• a cylindrical outer housing rotatably mounted about said inner housing and having a cylindrical wall, an aperture extending therethrough aligned with said indicia effective to pass said indicia past said aperture for viewing,
• a plurality of depressed grooves in the cylindrical wall on one of said housings, said grooves having walls projecting radially into said housing perpendicular to the circumference of said housing,
• a plurality of ribs positioned on the cylindrical wall on the other of said housings, said ribs having a face substantially perpendicular to said cylindrical wall and an inclined face in position to engage each of said depressed grooves during rotation of said outer housing, said walls of said depressed grooves spaced apart and adapted to simultaneously engage both faces of said rib in a manner effective to stop rotation of said housings relative to each other in one direction when said wedge-shaped rib and depressed grooves are engaged and yieldingly resist rotation of said housings relative to each other in the opposite direction when said wedge-shaped rib is engaged in said plurality of depressed grooves, and
• said indicia being disposed on said inner housing such that said plurality of indicia means are visible and aligned through said aperture when said wedge-shaped rib is engaged in said plurality of depressed grooves.

A closure member for a container, including in combination:

• an inner housing having means for mounting to the container,
• an outer housing rotatably mounted on and adapted to cooperatively nest about said inner housing,
• spring means positioned between said inner and outer housing to hold said outer housing outwardly in a relaxed position with respect to said inner housing, with said inner housing being rotatably mounted within said outer housing,
• at least one first abutment means mounted on one of said inner or outer housings between said inner and outer housing,
• at least one second abutment means mounted to the other of said inner and 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 positively stop rotation of said inner and outer housings relative to each other in the tightening direction when said inner housing is fully tightened to the container, with said at least one first abutment means and said at least one second abutment means being prevented from cooperatively engaging together by the outward force exerted upon the outer housing by the spring means when said outer housing is rotated in the opposite direction when the said inner housing is in the tightened condition, said spring means yielding to downward force upon said outer housing thereby permitting said at least one first abutment means to engage said at least one second abutment means to rotate said inner housing in the opposite direction from the fully tightened position to provide a twist-type child resistant closure member.
