Abstract
A hard-sided cooler box may include a channel or cylindrical-shaped hole that extends from the outside of the cooler box to the inside of the cooler box. This cylindrical-shaped hole or channel may be covered/sealed by one or more latches of the cooler box when the cooler box is closed, and the latches are secured. However, when the latches of the cooler box are released, the cylindrical-shaped hole or channel may be unblocked, and the air from the interior of the cooler box can escape to the outside of the cooler box before the lid is lifted from the body. This allows the lid to be opened with no struggle.
