An aseptic molding process of a container starting from a parison (20) made of a thermoplastic material, comprising steps of:

blowing a first fluid into the parison (20) located in a mould (10);
introducing the first fluid into the compensating chamber (14) of the mould (10) through an inlet (15);
evacuating the first fluid from the molded container;
evacuating the first fluid from the compensating chamber (14) through an outlet (16) fashioned therein;
sterilising the compensating chamber (14) by supplying to the inlet (15) a second fluid containing a sterilising agent and evacuating the second fluid from the outlet (16) of the compensating chamber (14).

A method and a molding station for producing containers filled with a liquid filling material from preforms made of a thermoplastic material. Thermally conditioned preforms are molded into containers and filled with the liquid filling material, which is supplied to the preforms under pressure as a pressure medium in a multi-part mold of a molding station. The mold is movable from a closed state into an open state in order to repeatedly supply a preform and subsequently remove a completely molded and filled container. Molding of the preform into the container is performed against the mold inner wall when the mold is in the closed state. Liquid is removed from the mold between temporally successive supplying processes starting with the conversion of the mold from the closed state into the open state. A working wheel including such molding stations, and a device including such a working wheel are also disclosed.

A method of forming and filling a container with an end product. Accordingly to the method, a preform is located within a mold assembly that defines the shape of the container and a nozzle assembly is moved so as to engage with at least one of the preform and the mold assembly forming a liquid tight seal. The end product is injected into the preform to simultaneously form a container from the preform and fill the container with the end product. After forming and filling the container, the nozzle assembly, which was used to inject the end product, is disengaged from the preform and/or mold assembly. After the nozzle assembly is disengaged, the filled container is removed from the mold assembly and residual end product is purged from the nozzle assembly.

An aseptic filling machine capable of performing molding and filling at the same time that has a compact facility size, requires a reduced initial investment, requires a reduced running cost because of its simplified process, and ensures an aseptic condition with reliability, and an aseptic filling method therefor. An aseptic filling machine includes a pre-heating sterilizing portion that sterilizes a preform, a heating portion that heats the sterilized preform, a molding and filling portion that fills the heated preform with a sterilized content under high pressure, thereby molding the preform into a bottle and at the same time filling the preform with the content, and a sealing portion that seals the bottle filled with the content. Before the aseptic filling machine starts operating, each portion is sterilized. During operation of the aseptic filling machine, aseptic air is supplied to each portion to maintain the aseptic condition.

Disclosed is an apparatus for expanding and filling plastic parisons to form plastic containers with a liquid medium, with at least one transforming station which has a hollow mould, inside which the plastic parisons can be expanded into plastic containers and can be simultaneously filled by application of a liquid medium, wherein the transforming station is arranged on a carrier and wherein the transforming station has a filling device which feeds the liquid medium to the plastic parisons under pressure, wherein the transforming station has a pressure chamber to which a gas can be applied, wherein for filling of the plastic parisons the filling device can be introduced into the pressure chamber and after the filling can be removed at least partially, and wherein a closing unit can be introduced into the pressure chamber, in order to close the expanded und filled plastic containers.

An injection device for injecting a pressurized liquid into the preform. The injection device includes a piston device having a piston body with a piston head arranged to reciprocate therein. The piston head cooperates with a sealing portion of the piston body to fluidicly isolate an inner chamber of the piston device. The piston body being in fluidic communication with a liquid source for admitting liquid into the inner chamber. The piston body including at least two outlet ducts for delivering pressurized liquid to the injection head. Each outlet duct opening defining an outlet port in a wall of the inner chamber. Each outlet port being centered on an outlet port center, wherein all the outlet port centers extend in the same radial planes of the inner chamber, are at the same distance from the piston axis and are arranged angularly in a regular manner around the piston axis.

To simply sterilize a blow-molding machine. A mist or gas of hydrogen peroxide or a mixture thereof is introduced through a valve block disposed adjacent to a molding die, thereby sterilizing at least the molding die and an extension rod that extends into the molding die through the valve block.

A fluid channel of a container processing system for processing containers, such as bottles, is described, the container processing system comprising a blow molding machine and a container processing machine arranged downstream of the blow molding machine in the process direction. The fluid channel is arranged downstream of the blow molding machine and upstream of the downstream container treatment machine in the process direction and comprises at least one component, through which the fluid can flow and which comprises at least one outlet opening through which the fluid can escape from the fluid channel in the direction of a bottom of a container transported in the process direction. The component is produced by a generative manufacturing method.

A station for forming a container from a preform. The station having a main body including a preform seat adapted to receive a preform and an injection assembly. The injection assembly including an injection nozzle, comprising an inlet and an outlet, that is movable between a retracted position and an injection position. An injection device arranged to inject liquid to the inlet of the injection nozzle. The injection device includes a housing, defining a main chamber having an actuation aperture, and a closing element movable relative to the housing and closing the actuation aperture. The injection nozzle and the housing of the injection device are rigidly fixed to each other so as to form a single unit.
