Container closure with venting seal

A container assembly, comprising:

• a container including a body portion and a neck portion having a mouth;
• and
• a container closure transitionable between an attached and a detached configuration with respect to the container neck portion,
• wherein the container closure includes:
• an outer cap including a top wall and an outer sidewall extending downward from the top wall;
• an inner cap secured within the outer cap, the inner cap including a bottom wall and an inner sidewall extending upwardly from the bottom wall, the inner sidewall is offset from the outer sidewall to define a space between the outer cap and the inner cap for receiving the neck portion of the container;
• a seal secured to the inner cap and forming a sealed connection between the neck portion and the closure when the closure is attached to the neck portion, the seal including a seal sidewall and a rim extending inwardly from the seal sidewall, the rim sealingly engaging the bottom wall,
• wherein the inner cap together with the seal define an air pathway therebetween that is in fluid communication between the 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,
• wherein the rim is configured to be lifted away from the bottom wall when a vacuum is formed within the container, allowing ambient air to flow through the air pathway and then through the air opening into the container to equalize interior air pressure of the container and outside ambient air pressure,
• wherein the bottom wall includes a recessed portion and the air opening is located in the recessed portion,
• wherein the rim is configured to be at least partially deformed into the recessed portion when a predetermined interior air pressure of the container is greater than outside ambient air pressure, deformation of the rim lifting the rim away from the bottom wall, allowing inside air to flow out through the air opening and then through the air pathway to ambient to equalize interior air pressure of the container and outside ambient air pressure.
