An apparatus for forming a container from a preform and delivering a predetermined volume of a liquid end product, formed by the addition of first and second liquid products, into the container. The apparatus includes a heating oven to heat the preform, a mold defining a cavity in the shape of the container, a stretch member coupled to an actuator to stretch the preform in the mold, an injection head configured to inject the second liquid product through the mouth of the preform so as to cause expansion of the preform within the mold thereby obtaining the container, and a preform filler to at least partially fill the preform with the first liquid prior to injecting of the second liquid product and before expanding of the preform into the container.

Method of delivering a liquid volume and associated apparatus

An apparatus for the fabrication of a container, comprising a mold defining the form of said container and container and configured to accommodate a substantially tubular preform, an injection head configured to interface with the preform and establish fluid communication with a cavity thereof; an injection valve configured to selectively permit fluid communication through said injection head, and a stretching rod slideably disposed within the injection head; said apparatus further comprising a displacement plunger being disposed coaxially about and mobile relative to said stretching rod between a retracted position substantially within the injection head and an extended position wherein said displacement plunger projects at least partially from said injection head.

Apparatus and method for fabricating and filling containers

An injection head for the fabrication of a container from a preform. The injection head interfaces with a preform to establish fluid communication between a liquid supply and the preform. An injection valve is disposed within the injection head and is configured to selectively permit fluid communication through the injection head. A liquid supply control mechanism and a control mechanism of the injection valve's opening allow fluid communication through the injection head. The control mechanism of the injection valve's opening is activated by the liquid under pressure in the injection head cavity when the liquid supply is opened.

An apparatus and method of delivering a predetermined volume of a liquid product, defined as the liquid end product, formed by addition of a first and second liquid product, into a thermoplastic container formed from a heated preform positioned in a mold and having an opening opposite an injection head. Prior to injecting the second liquid product into the preform causing expansion of the container, the preform is at least partially, filled with the first liquid product.

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.

Apparatus and method for fabricating containers

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.

A container-fabricating apparatus having an injection head establishing fluid communication between an injection fluid port disposed therein and a preform disposed in communication with a nozzle of the injection head. The apparatus also including a stretching rod moveable between a position projecting from the injection head through the nozzle and a substantially retracted position. The apparatus further includes a cleaning chamber at least partially defined by a hollow, elongate housing contiguous with and extending from the injection head, a plurality of cleaning chamber ports in a wall of the housing establishing fluid communication with the cleaning chamber, the stretching rod being substantially disposed within the cleaning chamber when disposed in the substantially retracted position.

Container-fabricating apparatus and a method for the cleaning thereof

An injection head for the fabrication of a container from a preform. An injection head interfaces with a mouth of the preform to establish fluid communication between a liquid supply and the mouth. The injection head includes an injection valve disposed within an outer shell of the injection head and configured to selectively permit fluid communication through the injection head upon displacement between an opened and a closed position. The injection head also includes an injection head cavity disposed between the injection valve and the outer shell and connected to the liquid supply. A liquid supply control mechanism and a control mechanism of the injection valve's opening allow fluid communication through the injection head. The control mechanism of the injection valve's opening is activated by the liquid under pressure in the injection head cavity when liquid supply is opened.
