A container (10) according to a preferred embodiment of the present invention 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 inner wall (20); however, the spacer elements prevent the outer wall from contacting the inner wall during non-standard use conditions.
