  • Patent number: 4296863
    Abstract: Containers such as those used for food stuffs having a generally frusto-conical initial shape are constrained into a forming die during the handling of the containers for injecting quantities of edibles and the like therein such that the containers are constrained to enter a die having a generally square configuration and then, while still in the die, the containers are filled with food or other material and a square lid is fed into position above the filled container and placed thereon to maintain the square configuration of the upper end thereof. The resulting containers provide a much more efficient packaging for equal volumes of product when compared with the more conventional frusto-conical shape containers.
