Abstract
A self-venting device includes a first component having an interior, a second component coupled to the first component so as to close the interior, and seal structure engaged between the first and second components in a sealed state so as to seal the interior from external agents. The seal structure includes a plurality of seal members, each having a resilient seal tip extending therefrom. The seal tips are constructed and arranged such that 1) when pressure inside the interior is equal to pressure outside of the device, the seal tips are compressed between the first and second components in the sealed state, and 2) when pressure in the interior is greater than the pressure outside of the device causing the second component to move away from the first component, the seal tips move to an unsealed state, permitting air to exit from the interior.
