Definitions

  • the process for varying an appearance of a container comprises the steps of injection molding a polymer preform having a non-reactive gas entrapped within the walls thereof; cooling the preform to a temperature below the polymer softening temperature; reheating the preform to a predetermined temperature greater than the polymer softening temperature; and blow molding the reheated preform, to prepare a container consisting essentially of a micro cellular foamed polymer having a non- reactive gas contained within the micro cellular foam cells, wherein the translucence of the container is varied based on the predetermined temperature.
  • the translucence of the container formed therefrom decreases.
  • the desired temperature may be increased to temperatures above 116 degrees Centigrade, thereby resulting in an opaque container having a silvery appearance or an opaque container having a white appearance, if PET is reheated too far above its glass transition temperature, or held at a temperature above its softening temperature for an excessive period of time, the PET undesirably will begin to crystallize.
  • the preform is heated to a temperature above which the mechanical properties of the material are exceeded by the increasing pressure of the non-reactive gas in the micro cells, the micro ceils undesirably will begin to expand thus distorting the preform.
  • the preform is blow molded, to prepare a container, consisting essentially of a micro cellular foamed polymer having a non-reactive gas contained within the micro cellular foam cells and having a desired appearance.
  • Methods and apparatus for blow molding a container from a polymer preform are well-known.
  • the color of the container is about Pantone Color Formula Guide number 420, 421 , 422, 423, 424, 425, 877, 8001 , 8400, or 8420.
