Abstract
A plastic core container is reinforced with a fibre-plastic composite for storing pressurized liquid and/or gaseous media and includes one or more connecting parts located in the neck and/or base and/or cylindrical container part. At least one connecting part is configured to receive a screw-in cylindrical or conical pressure-line feed device. A cylindrical insert is mounted in a connection shank of the plastic core container and has an end collar that envelops or surrounds the end of the connection shank. At least two seals are positioned so that at least one seal lies between the insert and the inner surface of the plastic connecting shank and at least one additional seal lies between the insert and the pressure-line feed device to guarantee a tight and permanent impermeability in the vicinity of the connecting parts, even under extreme, fluctuating thermal and operational stresses.
