Patent ID: 7819264

Claim:
A child-resistant package that includes: a container having a cylindrical finish with an open end, at least one external thread including a first end adjacent to said open end and a second end spaced from said open end, and at least one external lug separate from said at least one external thread and projecting radially outwardly from said finish adjacent to and circumferentially spaced from said second end of said thread remote from said open end, and a closure having a base wall, a skirt with at least one internal thread for engagement with said at least one external thread on said finish, at least one pair of internal lugs on said skirt adjacent to an end of said internal thread remote from said base wall, and at least one spring element for engaging said open end of said finish to bias said closure axially of said finish, said at least one external lug on said container finish having an axially oriented cam face that slopes in a clockwise direction away from said open end, said at least one pair of internal lugs on said closure skirt having a first lug with an axially oriented cam face that slopes toward said base wall such that threading said closure onto said finish in a clockwise direction causes said first lug on said skirt to cam axially away from said open end relative to said at least one external lug on said finish by compression of said at least one spring element, said at least one pair of internal lugs also having a second lug that engages said at least one external lug on said container finish when said closure is fully received on said container finish to limit clockwise rotation of said closure relative to said container finish, wherein said closure skirt has a stepped profile that includes a first portion on which said at least one internal thread is disposed and a second portion being connected to said first portion by inner and outer shoulders of said closure skirt and terminating at a skirt open end opposite of said base wall and being stepped to extend radially outwardly from said first portion and having an outer diameter larger than that of said first portion and having an inner diameter larger than that of said first portion on which said at least one pair of internal lugs is disposed, and said first lug is positioned proximate and just axially above said skirt open end and said second lug is positioned proximate and just axially below said inner shoulder of said closure skirt.
