Abstract
A mold for forming a container from a sheet of deformable material has upper and lower mold parts with die surfaces in conforming relation to one another. Upper and lower keys, each having a shear surface, are mounted in said upper and lower mold parts, respectively, so that the shear surfaces confront each other to form an opening in the container as the mold parts close. At least one of said keys is mounted so that its shear surface pivots on a plane normal to the motion of the closure of the mold parts.
