Claim:
A child-resistant closure and container package that comprises: a one-piece container having an open end surrounded by a cylindrical wall with a central axis and a cylindrical outer surface, a plurality of circumferentially spaced projections extending radially outwardly from said cylindrical outer surface of said wall adjacent to said open end, notches on undersides of said projections, and a plurality of circumferentially spaced flexible resilient spring elements extending radially outwardly from said cylindrical outer surface of said wall and angularly disposed between said projections, and a closure that includes a base wall, a cylindrical skirt extending from said base wall to an axial edge spaced from said base wall, a plurality of circumferentially spaced lugs extending radially inwardly from said skirt, and a circumferentially continuous annular wall extending axially from said base wall coaxially with and spaced radially inwardly from said skirt, said axial edge of said cylindrical skirt being adapted for axial edge abutment with said spring elements at positions on said spring elements spaced radially outwardly from said cylindrical outer surface to urge said lugs axially into said notches with said annular wall being in internal plug-sealing engagement with said open end of said container, removal of said closure requiring axial movement of said closure against said spring elements and rotation of said closure to move said lugs out of said notches.
