Abstract: With the view to obviating or mitigating the disadvantages that in processes for the production of containers, for example, product-filled containers, in which processes a substantial proportion of scrap is produced and that the space occupied by a purality of the containers prior to the product-filling thereof is considerable even if the containers are disposed in stacked relationship, there is provided a process for manufacturing a rimmed container preparatory to the filling and closing thereof from a one piece homogeneous blank, composed entirely of heat formable material containing just the requisite amount of material for forming the rimmed container to be filled, filling rim and an apparatus for performing the process, wherein the process includes the steps of uniformly heating a substantially rigid planar preshaped homogeneous blank of thermo plastic material, out to at least immediately adjacent the portion thereof adapted to form the container rim to a formable state while leaving the outermost periphery portion of the rim rigid, then while holding said rigid outermost peripheral blank portion forming the heated blank portion into a cavity, to produce a container. The invention further involves the heating of the blank to a sterilizing temperature to produce an aseptic container and subsequently filling the container e.g. with a food stuff, and closing same.
