Claim:
A package that includes: a closure having a skirt with a first plurality of internal lugs, a container having an open end and a second plurality of external projections, a spring between said closure and said container to bias said closure away from said container, said second plurality of external projections on said container including a first series of projections having under-notches alternating with a second series of projections without under-notches, said first plurality of lugs on said closure being equal in number to said first series of projections on said container and equal in number to said second series of projections on said container, such that there are twice as many projections on said container as there are lugs on said closure, and indicia on said closure and container for selectively engaging only said lugs with said projections of said first series of projections with under-notches in a child-resistant mode of operation, and engaging only said lugs with said projections of said second series of projections without under-notches in a non-child-resistant mode of operation.
