A package having child-resistant and non-child-resistant modes of operation, which includes: a container having a neck finish with an open end, an external surface surrounding said open end and at least one external first engagement element spaced from said open end, a closure having a base portion, a skirt extending from said base portion, at least one internal second engagement element on said skirt for engagement with said external first engagement element on said container neck finish in a child-resistant mode of operation, said skirt containing said second engagement element being severable from said base portion to convert said closure from a child-resistant mode of operation to a non-child-resistant mode of operation, and a first annular element within said skirt for sealing engagement with said external surface on said neck finish to seal said package in said child-resistant mode of operation and to bias said closure away from said neck finish, and a second annular element radially inward from said first annular element for snap-fit engagement with said open end in said non-child-resistant mode of operation with said skirt removed from said base portion to secure said closure to said container neck finish in said non-child-resistant mode of operation.
