Patent attributes
A package having child-resistant and non-child-resistant modes of operation includes a container having a neck finish with an open end, an external surface surrounding the open end and at least one external first engagement element spaced from the open end. A closure has a base portion, a skirt extending from the base portion, and at least one internal second engagement element on the skirt for engagement with the external first engagement element on the container neck finish in a child-resistant mode of operation. The skirt containing the second engagement element is severable from the base portion of the closure to convert the closure from a child-resistant mode of operation to a non-child-resistant mode of operation. A first annular element within the skirt is disposed for engagement with the external surface on the container neck finish to seal the package in the child-resistant mode of operation. A second annular element is disposed radially inwardly from the first annular element for engagement with the open mouth of the container neck finish to secure the closure to the container neck finish in the non-child-resistant mode of operation.
