Double wall container with internal spacer
A container according to a preferred embodiment of the present invention provides an inner wall and an outer wall wrapped therearound so as to define a double-wall container construction. A plurality of spacer elements are interposed between the inner and the outer walls so as to maintain a minimum thickness of an air space defined therebetween. In normal use conditions, the spacer elements do not contact the inner wall; however, the spacer elements prevent the outer wall from contacting the inner wall during non-standard use conditions.
