摘要： A hinged carton integrally molded of polystyrene foam and adapted to be locked shut by a flap extending upwardly from the bottom part of the carton inside a side wall of the carton cover and carrying one or more prongs so that the latter will be biased outwardly to snap into a corresponding number of holes provided in said cover side wall, the ruggedness of said carton being materially enhanced over similar cartons of the prior art by the local beefing up of said cover side wall in the immediate areas bordering said holes incidental to the functioning of a novel method of and apparatus for manufacturing said carton. Said apparatus is embodied optionally in a forming tool or in a form-and-trim tool and embraces relatively vertically reciprocable carton shaping matched-molds operating on a heated thermo-plastic web of polystyrene foam to produce one or more entire cartons with each reciprocation. In said method each hole in said cover side wall is formed by two matching wedge shaped cylindrical scissor blades which extend from the male and female matched molds to slide together face-to-face in a plane parallel with the direction the molds approach and separate from each other to comprise a hole-forming plug when said molds arrive at their final carton molding positions of proximity, said scissor blades being then mutually slidingly withdrawn vertically in opposite directions from the cover side wall hole formed thereby as the molds are separated vertically during the second half of a carton forming reciprocation, to release the carton from between the molds. The aforementioned beefing up of said cover side wall is enhanced by recessing the internal carton side wall forming faces of said molds in the areas thereof immediately adjacent to said scissor blades.
