<p>The present invention is provided with an insulated box body (21) that has an opening section (21a) and that is such that an insulating material (24) is foamed and fills the space between an outer box (23) and an inner box (22). The opening section (21a) has an outer box anterior section (23a) and an inner box anterior section (22a). The outer box anterior section (23a) is provided with: an outer box planar section (23b) extending parallel to the opening surface of the insulated box body (21); and an outer box standup section (23c) extending to the back of the insulated box body (21) from the end on the inner box (22) side of the outer box planar section (23b). The inner box (22) engages the outer box standup section (23c) and affixes the inner box anterior section (22a) to the insulating material (24) side of the outer box planar section (23b).</p> |
