Abstract: An overmolded preform and a container blow molded from the same are disclosed, wherein the overmolded preform and the overmolded container include an inner foamed layer.

Abstract: A product, e.g., insulated beverage bottle having a lid, and method of making it are disclosed. The product includes an outer hollow blow molded vessel in which an inner hollow blow molded vessel, is disposed. Each of vessel has a sidewall from which a flange projects. The flange of the outer vessel includes an annular wall. The flange of the inner vessel includes an engagement surface having an annular groove to receive the annular wall of the outer vessel. The inner vessel is arranged to be supported within the outer vessel on the flange of the outer vessel and with portions of the annular wall and annular groove engaging each other. Ultrasonic energy is applied to one of the flanges adjacent the engaging surfaces to concentrate the ultrasonic welding energy at those surfaces to produce a good double sided shear joint weldment thereat.

Abstract: A multi-layer preform having at least one foamed layer suitable for forming a multi-layer blow molded container having at least one foamed layer container is disclosed, the multi-layer container formed by a process comprising the steps of injection molding a polymer melt having a non-reactive gas entrained therein, causing entrained gas cells in the polymer melt to open to form a polymer preform having an open cell foam layer, cooling the preform to a temperature below the polymer softening temperature, reheating the preform to a temperature greater than the polymer softening temperature, and blow molding the preform in a second mold, to prepare the container. At least one layer of the container may be blended with an oxygen and/or carbon dioxide barrier material.

Abstract: A container comprises a micro cellular foamed polymer having foamed and unfoamed regions, wherein the container has one of a silvery appearance and a white appearance without the use of a colorant.

Abstract: An overmolded preform and a container blow molded from the same are disclosed, wherein the overmolded preform and the overmolded container include an inner foamed layer.

Abstract: A container comprises a micro cellular foamed polymer, and a non-reactive gas contained within the micro cellular foam cells, wherein the container has a silvery appearance. The process for making the container comprises 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 temperature above the polymer softening temperature, and blow molding the preform, to prepare a container comprising a micro cellular foamed polymer having a non-reactive gas contained within the micro cellular foam cells.

Abstract: A multi-layer preform having at least one foamed layer suitable for forming a multi-layer blow molded container having at least one foamed layer container is disclosed, the multi-layer container formed by a process comprising the steps of injection molding a polymer melt having a non-reactive gas entrained therein, causing entrained gas cells in the polymer melt to open to form a polymer preform having an open cell foam layer, cooling the preform to a temperature below the polymer softening temperature, reheating the preform to a temperature greater than the polymer softening temperature, and blow molding the preform in a second mold, to prepare the container. At least one layer of the container may be blended with an oxygen and/or carbon dioxide barrier material.

Abstract: A process for varying the appearance of a container is disclosed, the process comprises 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 appearance of the container is varied based on the predetermined temperature.

Abstract: An overmolded preform and a container blow molded from the same are disclosed, wherein the overmolded preform and the overmolded container include an outer foamed layer.
