Claim:
A child resistant closure and container combination comprising: a container having a container neck, said container neck having an opening defined by a rim; a child resistant closure having an outer cap operably engaging an inner cap, said outer cap having a top wall and a first plurality of ratchet teeth and said inner cap having a top wall and a second plurality of ratchet teeth; said first plurality of ratchet teeth and said second plurality of ratchet teeth being positionable between an on-drive position and an off-drive position, wherein an on-drive surface of said first plurality of ratchet teeth engages a corresponding first surface of said second plurality of ratchet teeth when in said on-drive position, said on-drive position permits said outer cap and said inner cap to turn as a single unit in a closing direction on said container, wherein an off-drive surface of said first plurality of ratchet teeth engages a corresponding second surface of said second plurality of ratchet teeth when in said off-drive position, said off-drive position permits said outer cap and said inner cap to turn as a single unit in an opening direction along with an axial deflection of said outer cap relative to said inner cap removing said child resistant closure from said container; a load bearing engagement between axially aligned teeth surfaces of each of said inner cap and said outer cap prevents axial displacement of said inner cap and said outer cap when said first plurality of teeth and said second plurality of teeth are in said on-drive position; a collar projecting downwardly from a bottom surface of said outer cap top wall, a plurality of axial ribs projecting from an inner surface of said collar; a central post projecting upward from a top surface of said inner cap top wall, said central post having two or more arcuate projections equidistantly spaced about said central post, each of said arcuate projections having a distal end spaced from a central axis of said central post and an opposing arcuate shaped outer edge; said distal end of each said arcuate projection having a first circumferential length and said arcuate shaped outer edge having a second circumferential length, wherein said second circumferential length is larger than said first circumferential length; at least one of said arcuate projections having an axial detent projecting from said arcuate shaped outer edge; and said axial detent of said at least one arcuate projection positioned at a first radius from said central axis of said central post and each of said plurality of axial ribs of said outer cap collar positioned at a second radius from said central axis, wherein said first radius of said axial detent is larger than said second radius of each of said plurality of axial ribs thereby said axial detent of said at least one arcuate projection operably engages said plurality of axial ribs of said outer cap collar to resist rotation of said inner cap and said outer cap.
