PRESSURE VESSEL AND ALSO APPARATUS AND PROCESS FOR PRODUCING A PRESSURE VESSEL BLANK COMPRISING AT LEAST ONE CONNECTION ELEMENT
The present embodiments provide an apparatus for producing a pressure vessel blank, comprising at least one connection element, a multi-part blow-moulding tool, and at least one blowing pin. The present embodiments further provide a pressure vessel comprising at least one connection element, a pressure vessel blank, and a supporting shell connected to and supporting the pressure vessel blank. An aspect of the present embodiments provides a process for producing a pressure vessel blank using an apparatus comprising at least one connection element that enables a shortened time for producing a pressure vessel blank with increased stability under pressure.
Gas-assisted base blow off methods for blow molding applications
This disclosure provides a method of manufacturing a polymer container according to a blow molding or stretch blow molding process, in which the base of the blow mold has at least one orifice for pressurized gas to enter the blow mold through the base. Introducing pressurized gas through the orifice in the blow mold base provides cooling assistance within the gas mold, much earlier than the cooling using conventional methods, which can reduce or eliminate the need for any post mold cooling. This method has been found to be applicable to non-hot fill application bottle and container manufacture.
Pressure vessel and also apparatus and process for producing a pressure vessel blank comprising at least one connection element
The present embodiments provide an apparatus for producing a pressure vessel blank, comprising at least one connection element, a multi-part blow-moulding tool, and at least one blowing pin. The present embodiments further provide a pressure vessel comprising at least one connection element, a pressure vessel blank, and a supporting shell connected to and supporting the pressure vessel blank. An aspect of the present embodiments provides a process for producing a pressure vessel blank using an apparatus comprising at least one connection element that enables a shortened time for producing a pressure vessel blank with increased stability under pressure.
Method and device for producing a container filled with a liquid filling material
A method and a device for producing a container filled with a liquid filling material from preforms made of a thermoplastic material, wherein each preform is thermally conditioned and subsequently, during a molding and filling phase, remolded into the container in a mold having at least one liquid filling material as a pressure medium. The filling material or parts of the filling material are supplied at at least two points in time and/or in at least two process phases with different contents of carbon dioxide and/or at different temperatures. In the second process phase, dry ice, particularly in form of pellets, is supplied.
Method and device for producing containers filled with a liquid filling material
A method and device for producing containers filled with a liquid filling material from preforms made of a thermoplastic material, wherein the respective preform is at least thermally conditioned and subsequently re-formed during a forming and filling phase into the container with at least one liquid filling material as a pressure medium having a filling pressure p.sub.2. The filling material or portions of the filling material is/are supplied at at least two points in time and/or during at least two process phases having different carbon dioxide contents and/or different temperatures. The filling pressure p.sub.2 of the container formed in the first process phase is reduced to a pressure p.sub.1 and filling material is supplied in the second process phase, after which the pressure of the container is reduced to atmospheric pressure p.sub.0. In the first process phase filling material that has been previously degassed and/or uncarbonated is supplied.
