A dispensing assembly for a pressure dispense package includes a connector having separate and distinct liquid and extraction conduits, and having a pressurization gas conduit. A liner fitment adapter may include a longitudinal bore to receive a probe portion of a connector defining a liquid extraction conduit, and may include a lateral bore to enable removal of gas. Insertion of a connector into a dispensing assembly simultaneously makes fluidic connections between (a) a gas extraction conduit and a dispensing volume; (b) a liquid extraction conduit and the dispensing volume, and (c) a pressurization gas conduit and a space to be pressurized within a pressure dispense vessel.

A high-pressure vessel includes a liner, an outer layer, a ferrule, and a seal member. The liner has a cylindrical shape, and is made of a first resin. The outer layer is joined to an outer peripheral surface of the liner, and is made of a second resin having a linear expansion coefficient that is lower than a linear expansion coefficient of the first resin. The ferrule is made of metal, is at least partly disposed radially inward of an inner peripheral surface of the liner, and is configured to provide communication between an internal space of the high-pressure vessel and an outside of the high-pressure vessel. The seal member is disposed between the inner peripheral surface of the liner and the ferrule, and is configured to seal a gap between the inner peripheral surface of the liner and the ferrule.

A storage tank for storing compressed fluid supplied from a source, comprising: an single piece elongate extruded body having an upper surface, a lower surface and side walls connecting the upper surface and the lower surface and at least one support member extending between the upper surface and the lower surface to define a plurality of storage chambers within the elongate body; and a pair of end caps mounted to an end of the elongate body to provide communication between the plurality of storage chambers, each end cap having a plurality of sockets formed thereon, at least one of which is connectable to the source for receiving the compressed fluid for storage within the plurality of storage chambers.

A hollow molded article having a joining site where two or more split objects are welded by plastic welding and comes into contact with pressurized hydrogen, wherein an average spherulite size in a portion which is 500 m deep inside from a surface of the hollow molded article is 20 m or less, and a tensile strength of a test piece containing the joining site of the hollow molded article is 80% or more based on a tensile strength of a test piece not containing the joining site of the hollow molded article.

A pressure vessel configured to store a pressurized fluid is provided including a plurality of lobes. Each lobe includes at least one vertically arranged interior wall. The plurality of lobes are positioned in a side by side configuration such that a first interior wall of a first lobe is positioned adjacent a second interior wall of a second adjacent lobe. The first interior wall and the second interior wall are configured to contact one another at a first point of tangency. A first tangent intersects the first lobe at the first point of tangency and a second tangent intersects the second lobe at the first point of tangency. The first tangent and the second tangent are separated by about 120 degrees.

A high-pressure vessel includes a liner, an outer layer, a ferrule, and a seal member. The liner has a cylindrical shape, and is made of a first resin. The outer layer is joined to an outer peripheral surface of the liner, and is made of a second resin having a linear expansion coefficient that is lower than a linear expansion coefficient of the first resin. The ferrule is made of metal, is at least partly disposed radially inward of an inner peripheral surface of the liner, and is configured to provide communication between an internal space of the high-pressure vessel and an outside of the high-pressure vessel. The seal member is disposed between the inner peripheral surface of the liner and the ferrule, and is configured to seal a gap between the inner peripheral surface of the liner and the ferrule.

This method for fixing a base with at least one element of a liner (24) of a tank (22) for a pressurised fluid comprising a liner (24) in particular comprises forming at least one element of the liner (24) by rotational moulding or by extrusion blow moulding of a polymer on the walls of a mould, the polymer being heated so as to be malleable, and in particular cooling the polymer so as to secure the second portion (40) of the base (34) to the polymer.

A dispensing assembly for a pressure dispense package includes a connector having separate and distinct liquid and extraction conduits, and having a pressurization gas conduit. A liner fitment adapter may include a longitudinal bore to receive a probe portion of a connector defining a liquid extraction conduit, and may include a lateral bore to enable removal of gas.

Insertion of a connector into a dispensing assembly simultaneously makes fluidic connections between (a) a gas extraction conduit and a dispensing volume; (b) a liquid extraction conduit and the dispensing volume, and (c) a pressurization gas conduit and a space to be pressurized within a pressure dispense vessel.

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.

A pressure vessel for storing gaseous fuel has a vessel wall which surrounds an interior, wherein one or more ribs are formed on the vessel wall. A pressure vessel system, particularly for a motor vehicle, includes at least two such pressure vessels. A method is disclosed to form the ribs on the vessel wall of the pressure vessel.
