Abstract
A method for forming a plastic container in which a heated end product is introduced into a heated preform to expand the preform into at least partial conform with the cavity surfaces of a mold, thereby forming a resultant container, of a first size, with a heated end product. The resultant container is then capped and shrunk to a second size, which is less than the first size. The shrinkage of the reluctant container is greater than the shrinkage of the end product thereby creating a positive pressure within the capped container.
