Claim Text:
1. A container for culturing a test sample, comprising: a molded monolithic single layer polymeric container body having an upwardly extending, visually transmissive wall with an inner surface and a wall thickness that is between about 0.2 mm and 10 mm; a thin gas barrier coating having a thickness between about 1 nm and 1000 microns comprising silica on the inner surface of the container body, wherein the gas barrier coating is visually transmissive; an internal top coating directly on the gas barrier coating, wherein the internal top coating is visually transmissive and the internal top coating is selected from the group consisting of a polyester, polyvinylidene chloride (PVDC), polyvinyl alcohol (PVOH), poly(acrylonitrile) (PAN), polyamide (PA), a polyurethane, an acrylic polymer, a polyetheramine, a metal oxide, a polypropylene film with reprocessed/recycled polyhydroxyamino ether (PHAE), a poly-para-xylylene polymer, acetylene, and any combination thereof; and a cap sealably attached to the container body to define a sealed container, wherein the sealed container has an oxygen transmission rate (OTR) after exposure to 121 degrees C. for 15 minutes and throughout a one year shelf life that is between about 0.0001-0.04 (cc/package/day/atm, measured at 20 degrees C., 40% RH), and wherein the container body has only two inner coating layers, the gas barrier coating as a first inner coating layer and the internal top coating as a second inner coating layer.
