ABSTRACT:
A preform, a method for blow molding a bottle, and a bottle formed from the preform and by the method are disclosed for use with beverages and the like wherein the bottles usually contain such beverages under pressure. The preform is shaped so that the resultant bottle is provided with a product-containing portion having a preferred hemispherical end portion and an integral bottom portion including a void therein for defining a hollow base portion which, in one form, contains fluid under pressure for balancing pressures related to the pressurized product. The hollow base portion provides for efficient use of material, and a minimal number of manufacturing steps, for providing a stable base for the hemispherical end portion of the product containing portion of the bottle.
