Abstract
A two-piece, press-twist, child resistant closure is formed with upwardly extending lugs, protrusions, ribs or channels on the upper surface of the outer closure member. The lugs assist in holding the outer closure against rotation while being axially depressed to engage the inner closure so that rotation of the container relative to the closure will effect removal of the closure. The closure system serves as a convenient system for arthritic or manually handicapped adults to use and still retain the child resistant nature of the closure for bottles containing harmful products.
