Abstract
A flip-top box is folded from a one-piece skillet by bringing a contents retainer panel (R) into overlapping relationship with a front panel (C.sub.1); thereafter pressing the skillet into a rectangular opening of a die (70), to cause certain panels of the skillet to stand perpendicular to rear panels of the container and lid, folding portions of the skillet projecting from the die into a plane parallel spaced from the rear panel and causing other portions to enter the die; and pressing the partially folded skillet into a rectangular opening of a second die opposite the first die to fold down the outside panels of the box to complete the box formation.
