Abstract
An injection head for a container-fabricating apparatus. The injection head includes a first nozzle establishing fluid communication between an injection liquid source and a preform cavity of a substantially tubular preform. The first nozzle is configured to mate with a mouth of the preform. An annular mouth seal, provided in the first nozzle, creates a seal with the mouth of the preform when disposed in contact therewith.
Claims12
An injection head for a container-fabricating apparatus, comprising a first nozzle configured to establish fluid communication between an injection liquid source and a preform cavity communicating with a mouth of a substantially tubular preform, said first nozzle is configured to mate with said mouth of said preform, an annular mouth seal provided in said first nozzle and defining an internal circumference of said first nozzle at a distal end thereof such that said first nozzle creates a seal with said mouth of said preform when disposed in contact therewith.
A method for fabricating a container comprising the steps of:
- providing a substantially tubular preform comprising a preform cavity in communication with a mouth disposed at an open end of said preform and a neck ring disposed about said open end at a distance from said mouth;
- disposing said preform in a mold having a mold cavity substantially in the form of a container;
- positioning an injection head in fluid communication with said preform, said injection head comprising a first nozzle with an annular mouth seal bearing against said mouth of said preform and creating a seal therewith;
- and
- injecting a volume of an injection liquid from an injection liquid source through said injection head into said cavity of said preform, said preform being thereby induced to expand into the shape of said mold cavity.
