• C. a plurality of tying links extending between the parallel walls on the interior of the member and comprising
• i. each such link being integral with a first parallel wall and comprising an indented formation having a bottom which is generally parallel with said first parallel wall from which the indented formation extends,
• ii. the depth of the indented formation being such as to carry the said bottom into engagement with the interior surface of a portion of the second and opposite parallel wall and forming a web therewith which is approximately twice the thickness of either of the parallel walls,
• iii. the indented formation being produced during the blow-molding operation whereby the said bottom and the said portion of the respective parallel walls are permanently welded together,
