Abstract: Placing a lay-flat container body into a lay-flat container lid, opening the container, closing the top closure panels and leaving the bottom closure panels open, thereafter placing a product into the container, raising the container body until the bottom closure panels clear the product, closing the inner bottom closure panels, placing adhesive on the bottom panels, closing the outer bottom closure panels, adhering the bottom closure flaps to each other and vibrating the container to force the container body down into the container lid. The apparatus has a filler, a pair of clamps that grasp and lift the container body upwardly, plows that fold the closure panels into place, glue heads that place adhesive on the closure panels and tilting weights and a vibrating table to seal the closure panels and force the container body back into the container lid.
