    摘要: The invention provides a light weight self-standing blow molded two-liter carbonated beverage container base design having a unique petaloid base. The base comprises a petaloid design which has a plurality of at least three (preferably five) feet with an ever increasing radius of curvature joining the feet to the underlying base from the radially outer portion of the feet to the radially inner portion of the feet, a controlled radius from the axis of the container to that curvature and an area of material flow in feet ankles and straps therebetween to promote adequate material flow during blow molding, to the radially outer most areas of the feet and straps.

    摘要: The invention provides a self-standing blow molded two liter carbonated beverage bottle 1 weighing under 50 grams and having a unique petaloid base 7. The base comprises a petaloid design which has a plurality of at least three (preferably five) feet 9. Between each adjacent pair of feet is a radially extending valley 12 the width of which decreases with increasing radial distance from the bottles longitudinal axis toward a point of convergence 14 radially outside the bottle's diameter. The valley floor generally follows the hemispherical base shape and opens to an extended portion 13 of that base shape lying radially outwardly of the feet. The valley and extended portion initial pressurization of the bottle, deformation of the extended portions outwardly with a resulting raising of the center of the base away from the support surface.

    摘要: A method of forming a wide mouth blow molded thermoplastic container comprising the steps of i) stretch blow molding from a preform, an intermediate article defining the container with the mouth being threaded and/or flanged, the mouth terminating in an accommodation element having a neck finish that supports the preform in the blow mold; ii) heat setting the intermediate article including the entire container while still in the mold, and iii) removing the intermediate article of manufacture from the mold and severing the accommodation element to produce the container, and an article when made by the method. The method also includes post forming of a rim portion of the container following separation of the container from the accommodation element.
