<p>Disclosed are preforms (30) which incorporate improvements in the region of the neck (32) and upper segment of the body (34) to allow the production of lightweight containers (82), such as bottles suitable for containing water or other beverages. In accordance with certain embodiments, the improvements include a thinner neck finish area than conventional bottles, where the thinner area is extended into the upper segment of the body portion below the support ring (38). Reducing the thickness in these areas of the bottle allows for less resin to be used in forming the preform and bottle.</p> |
