Abstract

A container closure includes an outer cap, an inner cap, and a seal. The outer cap includes a top wall and an outer sidewall extending downward from the top wall. The inner cap is secured within the outer cap and includes a bottom wall and an inner sidewall extending upwardly from the bottom wall. The seal is secured to the inner cap and includes a seal sidewall and a rim extending inwardly from the seal sidewall. The seal sidewall sealingly engages the inner sidewall and the rim sealingly overlaps the bottom wall. The inner cap together with the seal define an air pathway in fluid communication between a space between the outer and inner caps and an air opening formed on the bottom wall of the inner cap and selectively covered by the rim.
