1. An insulating device comprising:
a body portion extending along a body axis, the body portion comprising:
a first surface feature, at a first location along the body axis, extending between a first surface end and a second surface end, the first surface end defining a first surface cross-sectional size, the second surface end defining a second surface cross-sectional size, wherein the second surface cross-sectional size is less than the first surface cross-sectional size;a second surface feature, at a second location along the body axis, extending between a third surface end and a fourth surface end, the third surface end defining a third surface cross-sectional size, the fourth surface end defining a fourth surface cross-sectional size, wherein the fourth surface cross-sectional size is less than the third surface cross-sectional size; and a flange portion extending along a flange axis that is substantially parallel to the body axis, the flange portion comprising a flange wall defining a flange opening into which the body portion is received, the flange wall of the flange portion comprising:
a first mating portion at a first location along the flange axis, the first mating portion configured to engage the first surface feature of the body portion; anda second mating portion at a second location along the flange axis, the second mating portion configured to engage the second surface feature of the body portion. |
