ABSTRACT:
A lined bulk container which is formed from a box blank and a liner blank and wherein the liner blank is folded upon itself to be of double thickness. The liner blank is folded upon itself with two liner portions thereof being adhesively bonded together, after which the folded liner blank is adhesively bonded to the box blank and then the combined blanks are partially folded to form a knocked-down box. The blanks have aligned transverse fold lines facilitating the folding of the blanks to form box body panels. The liner portion which is bonded to the box blank has along the remote fold lines thereof slots which facilitate folding, the length of the slots controlling the square folding of the combined blanks whereby the knocked-down boxes can be manufactured in a continuous flow and without at least the adhesive which bonds the liner blank to the box blank having set.
