Abstract:
The present disclosure, in one embodiment, relates to a liner-based assembly having an overpack and a liner disposed within the overpack. The liner may be formed by blow molding a liner preform within the overpack to form a blow molded liner substantially conforming to the interior of the overpack and generally forming an interface with an interior of the overpack. The present disclosure, in another embodiment, relates to a liner-based assembly including a blow-molded overpack comprised of polyethylene terephthalate, a blow-molded liner disposed within the overpack, the liner comprised of a polymer material, wherein the overpack and liner have a combined wall thickness of about 0.3 mm or less, and a base cup configured to at least partially surround an exterior of the overpack. In some embodiments, the liner has a volume of up to about 4.7 liters and an empty weight of between about 260-265 grams.
Abstract:
A valve (200)for a blow molding machine(100)and a method for actuating the same are provided. The includes a housing (202)having an inlet (204)and an outlet (206), a piston (208)movable inside the housing(202), and a pressure compensation chamber (218)positioned between the pressure compensation end (220)of the piston (208)and the housing(202). The piston (208)includes a pressure compensation end (220), a valve seat end(222), and a pressure compensation bore(210). The pressure compensation chamber(218)is in fluid communication with the inlet (204)via the valve seat end (222)of the piston (208)via the pressure compensation bore(210). The piston (208)is configured to actuate independently of an inlet fluid pressure (236).
Abstract:
The invention concerns a method of delivering a predetermined volume of a liquid product into a thermoplastic container formed from a heated preform (3) positioned in a mold (2) having an opening opposite an injection head (6a), characterized in that, prior to injecting the liquid product in the preform (3) causing expansion of the container, the method includes a step of, at least partially, filling the preform (3) with an inert component in relation to the liquid to be injected.
Abstract:
The invention concerns a 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 (3) positioned in a mold (2) having an opening opposite an injection head (6a), characterized in that,prior to injecting the second liquid product in the preform (3) causing expansion of the container, the method includes a step of, at least partially, filling the preform (3) with the first liquid product. The invention also relates to the apparatus associated with the claimed method.
Abstract:
Station for forming a container operable in an injection configuration and in a displacement configuration The station comprises a main body (48) including a preform seat (53) adapted to receive a preform (14) and an injection assembly (1) comprising: - an injection nozzle (2) comprising an inlet (8) and an outlet (10), said injection nozzle (2) being movable between a retracted position and an injection position, and - an injection device (4) arranged to inject liquid to the inlet (8) of the injection nozzle (2), said injection device (4) comprising a housing (32), defining a main chamber (34) having an actuation aperture (35), and a closing element (42) movable relative to the housing and closing the actuation aperture (35). The injection nozzle (2) and the housing (32) of the injection device (4) are rigidly fixed to each other such as to form a single unit.
