Abstract
A refrigerator cabinet having an outer shell with an opening at the front thereof, an inner liner within and spaced from the shell and bonded thereto by a body of foamed plastic insulating material. A rigid foam member is located in the space between the shell and liner between the insulating material and the outer shell opening. The rigid foam member has a passage for venting air from the insulation space during foaming of the insulation material and that passage is undulated sufficiently to prevent the foam insulation material from passing therethrough.
