ABSTRACT:
An apparatus for pressforming a paperboard sheet into an articulable pressformed container. The apparatus includes a pair of male and female, matingly engagable dies, which have interfacing forming surfaces in the shape of a container for engaging a paperboard sheet. A first one of the dies has a plurality of ridges extending from the forming surface and a second one of the dies has a plurality of grooves within the forming surface. The grooves register with the ridges when the dies matingly engage for creating creases in the paperboard sheet. The invention also includes a method for simultaneously shaping the container and forming fold creases on the container thereby making the container articulable.
