Abstract
An injection head for a container fabricating machine. The fabricating machine includes a first nozzle configured to establish fluid communication between an injection liquid source and a preform cavity in communication with a mouth disposed at an open end of the preform. The first nozzle of the injection head includes a substantially tubular spout configured to be inserted into the open end of said preform and thereby create a seal with the preform.
Claims27
An injection head for a container fabricating machine, comprising a first nozzle configured to establish fluid communication between an injection liquid source and a preform cavity of a substantially tubular preform, said preform cavity being in communication with a mouth disposed at an open end of said preform, wherein said first nozzle further comprises a substantially tubular spout configured to be inserted into said open end of said preform and create a seal 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;
- 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 configured to establish fluid communication between an injection liquid source and said preform cavity of said preform, said first nozzle comprising a substantially tubular spout inserted into said open end of said preform and creating a seal therewith;
- and
- injecting an injection liquid from said injection liquid source through said injection head into the preform cavity of said preform, said preform being thereby induced to expand into the shape of said mold cavity.
The method as claimed in claim 18, further comprising, during the injecting step, injecting a compensation fluid into the nozzle cavity through a channel provided in the injection head establishing fluid communication between said nozzle cavity and a source of pressurized compensation fluid.
