US Patent 11072462 Pan with integrated air gap

A pan includes a base, a sidewall, and a lip. The sidewall extends from and around a first periphery of the base. The base and the sidewall cooperatively define a cavity. The lip extends from and at least partially along a second periphery of an end of the sidewall opposite the base. The lip has a first portion and a second portion. The first portion of the lip is configured to engage a third portion of a second pan when the pan and the second pan are in a nested arrangement such that engagement between the first portion of the lip and the third portion of the second pan forms an air gap between the pan and the second pan when in the nested arrangement.
