Bottle cap and method therefor

摘要

A closure assembly (100) includes an inner cap (202) with threading along an inner surface. A threading profile extends along an outer surface of an inner cap sidewall (300). An outer cap (200) is coupled with the inner cap. The outer cap includes an outer cap sidewall (400) extending along at least a portion of the inner cap sidewall (300), and the outer cap sidewall is substantially cylindrical and uniformly smooth along at least an exterior face. The outer cap sidewall (400) is sized and shaped to conceal the threading profile. An annular rim (208) of the outer cap extends from an open end of the outer cap, and the annular rim is inwardly bent toward the inner cap. In another example, the annular rim extends over the inner cap sidewall and couples the outer cap with the inner cap with an interference fit.
