Abstract
A process and apparatus is disclosed for thermoforming an all plastic carton used to house a fluid with integral, kidney-shaped depressions in adjacent side walls of the carton to serve as handle members to aid in pouring the fluid contents from the carton. A pair of mandrels are inserted through opposite ends of a tubular enclosure formed from the carton blank. The mandrels are provided with a toroidal shaped cavity where they meet inside the enclosure. The enclosure is heated and a pair of complementally shaped, dies are rotated exteriorly of the enclosure into the toroidal cavity in the mandrels on adjacent sidewalls of the carton to form the handle depressions.
