A plunger (10) for supporting a wall (46) of e.g. a refrigerator door on filling of expanding an hardening foamed plastic (52) on the other side of the wall shows an evacuated bag-formed part (18) filled with a particulate material (20), which part has a surface (42) showing an impression of the form of the wall (46). The plunger (10) is reshapable, so that it can serve as a plunger for walls (46) of different forms. <IMAGE> |
