Abstract

An insulating device includes a body portion including a first surface feature extending between a first surface end and a second surface end. The first surface end defines a first surface cross-sectional size. The second surface end defines a second surface cross-sectional size. The second surface cross-sectional size is less than the first surface cross-sectional size. The body portion includes a second surface feature extending between a third surface end and a fourth surface end. The third surface end defines a third surface cross-sectional size. The fourth surface end defines a fourth surface cross-sectional size. The fourth surface cross-sectional size is less than the third surface cross-sectional size. The insulating device includes a flange portion having a flange wall. The flange wall includes a first mating portion that engages the first surface feature and a second mating portion that engages the second surface feature of the body portion.
