An apparatus is provided for the storage and dispensing of a sorbable gas. The apparatus includes a storage and dispensing vessel constructed and arranged for containing a solid-phase physical sorbent medium having a sorbable gas adsorbed by said sorbent medium. The dispensing vessel includes a top head having a dispensing valve coupled to the vessel for discharging the sorbable gas therefrom. The dispensing valve is in fluid flow communication with a wick that extends below the upper third of the vessel top head. The wick collects the sorbable gas for discharge of the gas through the dispensing valve.

A pressure vessel with a flushing lance, a transport container with pressure vessels and methods of filling and producing this pressure vessel are disclosed which comprises an inner vessel, an outer layer applied on the inner vessel, a valve connection piece arranged on one of the terminal caps of the inner vessel and a hollow flushing lance that is open to the outside and is guided through the valve connection piece and held therein in a sealing manner, wherein the flushing lance protrudes into the storage volume and is provided with a perforation along its entire length up to a first end of the flushing lance facing the terminal cap that lies opposite the valve connection piece in the storage volume for a gas exchange with the storage volume, wherein the flushing lance extends to the terminal cap which lies opposite the valve connection piece.

To suppress the degradation of sealing property of a pressure vessel and the deterioration of a sealing member, and to reduce the workload and cost of manufacture, a blow molding device includes a pair of molds configured to be clamped to sandwich a parison from both lateral sides, and a blow pin configured to form a neck portion together with the molds. The blow pin includes a blow pin body portion having an outer circumferential surface of a shape corresponding to an inner circumferential surface of the neck portion, and a ring portion forming an annular recess portion between the blow pin body portion and the ring portion to form an outer circumferential surface of a tip portion of the neck portion, which is a smooth surface without any parting line.

A tank includes a liner that includes a barrel portion in a cylindrical shape and a pair of dome portions provided at both ends of the barrel portion in the axial direction, and a reinforcing layer that covers the liner and that is formed from a fiber reinforced resin formed by impregnating a fiber bundle with a resin. A portion of the reinforcing layer that covers the dome portions includes a radial arrangement layer in which fibers of the fiber bundle are arranged radially along the radial direction of the dome portions when seen in the direction of an axis of the tank.

A high-pressure vessel includes a liner and a reinforcing layer. The reinforcing layer includes an inner reinforcing layer and an outer reinforcing layer. Further, the inner reinforcing layer includes a first covering portion, a third covering portion, and a second covering portion. Edge surfaces of the first covering portion and the third covering portion that face each other are in contact with each other. Edge surfaces of the third covering portion and the second covering portion that face each other are also in contact with each other. The outer reinforcing layer covers the outside of the first covering portion, the third covering portion, and the second covering portion.

A pressure vessel includes: a barrel part disposed in a predefined square area and having a diameter corresponding to a length of one side of the square area; a first nozzle member disposed at one end of the barrel part; a second nozzle member disposed at an opposite end of the barrel part; and clamp rings disposed in the square area, positioned outside the barrel part, and configured to lock the first and second nozzle members to the barrel part, thereby improving spatial utilization and a degree of design freedom.

The present invention discloses a knob cap for a high-pressure tank including a first knob cap portion having a coupling groove coupled to a knob of a liner of the high-pressure tank in a lower surface, including a peripheral wing portion extending outward to be in contact with a surface of the liner to outside of a lower portion, and having a column portion in the shape of a column extending upward in a center; and a second knob cap portion integrally coupled with the first knob cap portion, having the column portion of the first knob cap portion inserted into a hollow, and including a plurality of inner grooves in the shape of a column having an upper end opened outside of the hollow and extending downward.

A high-pressure container includes a liner and a fiber layer formed of reinforcing fibers wound around an outer periphery of the liner. The fiber layer has a plurality of hoop layers in which reinforcing fibers are wound in the circumferential direction of the liner to reinforce the body portion. The reinforcing fibers used for a first hoop layer from an inner peripheral side of the fiber layer or the first hoop layer and one or more hoop layers subsequent to the first hoop layer, among the plurality of hoop layers, have a structure in which a plurality of filaments are twisted so as to be inclined with respect to a fiber bundle direction, and have a property of more easily elongating than the reinforcing fibers used for the hoop layer that is located on an outer peripheral side of the fiber layer.

A manufacturing method for a high-pressure tank includes joining a cylindrical member and dome members to each other so that a first reinforcing layer and a second reinforcing layer to which a cap is attached are formed, and after a resin material is poured inside the first reinforcing layer, rotating the first reinforcing layer so that the resin material covers an inner surface of the first reinforcing layer, and solidifying the resin material so that the liner is formed. The cap is attached to the first reinforcing layer so that a recessed portion in which the resin material is collected is formed between the cap and the first reinforcing layer. After the first reinforcing layer is rotated, the resin material is solidified in a state where the cap side is positioned on a lower side.

Method for preparing a hydrogen tank including at least one sealing layer of a composition including at least one polyamide P1, and at least one base in order to provide the tank with at least one opening, wherein the method includes: providing of at least one base, the at least one base being covered by at least one layer of a composition including at least one adhesion primer; preparing the at least one sealing layer; fastening the at least one base to the at least one sealing layer.
