Claim:
An overflow pan, comprising: a substantially flat base portion; a sidewall structure extending transversely upward from the base to define a fluid-retaining basin, the sidewall structure comprising: a first portion permanently affixed to the base portion; a second portion connectively affixed to the base portion and movable between a first position in which the second portion is positioned relative to the first portion so as to maintain a fluid-tight seal between the second portion and the first portion, and a second position in which at least part of the second portion is spaced apart from the first portion, and wherein the second portion is biased to return to said first position; and a lip extending generally horizontally outward from at least a portion of an upper edge of the second portion in a direction in which the second portion is movable, wherein: the second portion is configured to interact with an outwardly extending portion of an appliance disposed within the fluid-retaining basin to move the second portion towards the second position to permit extension of the longitudinally extending portion beyond the second portion of the sidewall; and the lip is configured to interact with the longitudinally extending portion of the appliance to move the second portion towards the second position to permit retraction of the outwardly extending portion of the applicance.
