| 发明名称 | Method of forming a container | ||
| 摘要 | An apparatus and method for forming a plastic container is provided. The method includes disposing a preform into a primary mold cavity and applying pressurized air to urge the preform to conform to the shape of the primary mold cavity to form a primary article. The primary article is then permitted to shrink to a predetermined volume. The method can further include exposing the primary article to an internal vacuum to facilitate shrinking to a predetermined volume. The method further includes disposing the primary article into a second mold cavity and applying pressurized air to urge the primary article to conform to the second mold cavity to form an intermediate article. Finally, at least a portion of the intermediate article is trimmed off to form a final container. | ||

| 主权项 | 1. A method of manufacturing a blow molded container comprising: a. disposing a preform into a primary mold cavity; b. applying pressurized air to urge the preform to conform to the shape of the primary mold cavity to form a primary article; c. permitting the primary article to shrink to a predetermined volume; d. disposing the primary article into a second mold cavity; e. applying pressurized air to urge the primary article to conform to the second mold cavity to form an intermediate article; and f. trimming off at least a portion of the intermediate article to form a final container; wherein the permitting the primary article to shrink to the predetermined volume is induced through application of a vacuum. | ||
