Abstract: An apparatus for vacuum thermoforming and printing plastic articles from a continuous web of plastic material in which a rotatable vacuum thermoforming drum has a plurality of vacuum thermoforming dies mounted on circumferentially surfaces. The drum further comprises a gear path and a cam path, each with a plurality of substantially flat and curved sections. A print structure in a frame includes a device for imparting ink to the articles after they are formed, and a linear bearing adapted to allow the printing cylinder to move in a constrained motion substantially normal to the central axis. The printing cylinder comprises a shaft with a pinion gear to engage the gear path and a cam roller to engage the cam path. As the drum rotates, the articles are formed, printed and separated in substantially a single operation.
Abstract: A bowl-shaped molded plastic cradle has bottom contours which are complemental to the topographical features of a thermoformed drink cup lid so that the cradle and lid may be nested within one another in a laterally stable association. This allows a food product such as a donut to be placed within the tray and marketed with, for example, hot coffee in a synergistic association.

Abstract: A method and apparatus for vacuum thermoforming disposable drink cups lids. The method and apparatus include the step of imparting printing to the lids in two or more colors. The step of imparting printing to the lids is done while the lids are in contact with the vacuum thermoforming platen.
