A container (10) according to a preferred embodiment of the present inven tion provides an inner wall (20) and an outer wall (30) wrapped therearound so as to define a double- wall container construction. A plurality of spacer elements (38) are interposed between the inner (20) and the outer walls (30 ) so as to maintain a minimum thickness of an air space defined therebetween . In normal use conditions, the spacer elements (38) do not contact the inne r wall (20); however, the spacer elements prevent the outer wall from contac ting the inner wall during non-standard use conditions.
