Abstract
A pressure vessel having an inner container made of thermoplastic plastic, and at least one metal part embedded in the inner container. A collar that includes the metal part is formed on the inner container, the collar being configured such that it is gas-tight with respect to the metal part.
Claims20
A method for producing a pressure vessel comprising an inner container made of thermoplastic plastic, the method comprising:
- blow-molding the inner container from a preform in a tool;
- and
- embedding, during the blow molding, at least one metal part in the inner container,
- wherein blow molding the inner container includes forming a collar, that includes the metal part, on the inner container so as to be gas-tight with respect to the metal part.
1 more element
A pressure vessel, comprising:
- an inner container composed of thermoplastic plastic;
- at least one metal part embedded in the inner container;
- and
- a collar that includes the metal part formed on the inner container and which is gas-tight with respect to the metal part.
1 more element
A tool for producing a pressure vessel, the tool comprising:
- an injector to inject a gas, the injector having a receptacle for at least one metal part of the pressure vessel;
- and
- mold halves which receive the at least one metal part to permit the at least one metal part to be inserted into a preform from which the inner container of the pressure vessel is formed,
- wherein the injector and the mold halves are configured such that by blow molding, by way of injection of gas through the injector and by closure of the mold halves, a collar that includes the at least one metal part, is formed on the preform, the collar being formed in the blow molding such that it is gas-tight with respect to the metal part.
