Abstract: A container formed of an erected body blank and a pair of erected wall blanks made of corrugated board material, and a method of forming same. The body blank has a bottom panel and an erected, upstanding pair of end wall panel areas at opposite ends of said bottom panel. Each of the pair of wall blanks has an end wall portion and at least one extension portion. The erected pair of wall blanks are disposed generally along a perimeter of the bottom panel of the erected body blank adjacent to the end wall panels such that the end wall portions of the pair of wall blanks and the upstanding pair of end wall panel areas of the body blank are attached together, and the at least one extension portion extends inside of the perimeter of the bottom panel.

Abstract: An apparatus and method for the vacuum assisted bonding of sections of corrugated cardboard and for manufacturing corrugated cardboard. A pressure plate has a bore for applying a vacuum therethrough. A first section of corrugated cardboard has an orifice which is aligned with the bore in the pressure plate. Adhesive is applied between the first section of corrugated cardboard and a second section of corrugated cardboard and the second section is placed adjacent to the first section away from the pressure plate. A vacuum is applied through the bore in the pressure plate and orifice in the first sections to cause the first and second sections to be drawn and adhered together. In the manufacture of corrugated cardboard, vacuum and optionally hot air are applied to opposite edges of the sandwiched core of fluted linerboard with adhesive and overlaying flat linerboard to draw them together to form the corrugated cardboard.
