Claim:
1. A method of simultaneously forming and filling a container with a carbonated liquid beverage, the carbonated liquid beverage of a resultant filled and sealed container having a defined partial pressure of dissolved carbon dioxide, the method comprising: placing a thermoplastic polymer preform within a mold, stretching the thermoplastic polymer preform within the mold, at room temperature (68° F. to 77° F.) and prior to injecting of the carbonated liquid beverage into the preform, increasing pressure of the carbonated liquid beverage to a pre-load pressure, the pre-load pressure being greater than the defined partial pressure of dissolved carbon dioxide in the carbonated liquid beverage in the resultant filled and sealed container at room temperature, maintaining the carbonated liquid beverage at rest and at the pre-load pressure prior to injecting of the carbonated liquid beverage into the preform, and with the carbonated liquid beverage at rest and at the pre-load pressure, initiating injection and continuing injecting of the carbonated liquid beverage into the preform from an injection head, after stretching of the preform has started, to form the container.
