A method for producing containers filled with liquid content from preforms made of thermoplastic material. The liquid content is fed as a pressure medium into thermally conditioned preforms during a forming and filling phase in a mold of one of a plurality of forming stations arranged circumferentially spaced apart on a common, continuously rotationally driven working wheel. A compensating device compensates for thermal consequences of centrifugal force acting on the liquid content fed into the preform during the forming and filling phase. The compensating device imparts a temperature profile to the preform in a circumferential direction, which is not point-symmetrical in relation to a longitudinal axis of the preform to produce a thermally differentiated partial circumferential region. The preform is inserted into the mold such that the thermally differentiated partial circumferential region faces in a radial direction of the working wheel.

Method for the production of filled containers from thermally conditioned preforms

The method relates to a method for filling a container () with carbonized liquid filling material and for closing the filled container, in which the filling material is introduced in a filling station () by a filling head () at defined filling pressure into the container (), wherein the filling head () is firstly moved from an idle position, which permits supplying and inserting a container () into the filling station (), into a working position toward the inserted container, in which an end region () of the filling head seals off the opening () of the container, the container () is then filled, the filling head () is moved after completion of the filling phase back out of the working position into an idle position spaced apart from the container () and the container () is then closed in the filling station () using a cap () at least enough that filling material can no longer escape, and the container () is then removed from the filling station (), characterized in that before the movement of the filling head () from the working position into the idle position spaced apart from the container (), an overpressure lying between the ambient pressure and the filling pressure is set in a pressure chamber () of the filling station () surrounding the opening () of the inserted container (), which overpressure is selected in such a way that possible foaming up of the filling material located in the container () is minimized enough that filling material does not escape from the container () when the filling head () is raised out of the working position after the filling procedure.

Method and device for filling containers with carbonized filling material and subsequently closing the filled containers

The invention relates to a method for producing a container from a thermoplastic parison, the container being produced from the parison with the aid of a fluid, either by blow molding and subsequent filling with a fluid that is in particular liquid, or being produced by hydroforming and subsequently containing the liquid fluid as contents, and, during the blow-molding process and/or when receiving the in particular liquid fluid, the container revolves about and is spaced apart from an axis of rotation extending, in particular, vertically, in a mold that can be opened. According to the invention, the closed mold adopts, at least temporarily, an inclined position, i.e. that deviates from a perpendicular position.

Method and device for producing a container from a thermoplastic parison

The invention relates to a method and an apparatus for producing liquid-contents-filled containers () from preforms () by contents being introduced into the preform () under a filling pressure, wherein the contents are placed under pressure by a pressure pump () and are introduced into the preform () at a molding and filling station () by a filling valve (). A pressure accumulator () arranged between the pressure pump () and the filling valve () is subjected to pressure and is filled with a volume of contents by the pressure pump (). The invention is distinguished in that a displacement pump () having a filling chamber () for the contents and having a displacement body () guided so it is movable therein is provided, wherein the displacement body () divides the chamber () into a first partial chamber () on the filling station side and a second partial chamber () facing away from the filling station, each of which can be brought into a fluidic connection with the pressure accumulator (). The displacement body () has a drive connection to a drive unit () and is drivable by the drive unit (), wherein when the filling valve () is opened, the drive unit () and/or the pressure accumulator () each at least temporarily apply a drive force to the displacement body (), and at the same time the displacement body () displaces at least a part of the quantity of contents required for the forming of the preform () in the direction of the preform ().
