Abstract

A high-pressure container includes a plurality of body parts arranged side by side, and each of the body parts has a cylindrical shape and has an opening at at least one of its axially opposite end portions. The high-pressure container also includes a cap configured to close the openings of the body parts as a unit, and a communication channel provided inside the cap for communicating interiors of the body parts with each other.

First claim

What is claimed is:

1 . A high-pressure container comprising:
a plurality of body parts arranged side by side, each of the body parts having a cylindrical shape and having an opening at at least one of axially opposite end portions of the body part; a cap configured to close the openings of the body parts as a unit; and a communication channel provided inside the cap and configured to communicate interiors of the body parts with each other.

2 . The high-pressure container according to claim 1 , wherein:
each of the body parts is covered with a first fiber reinforced resin member having a fiber direction corresponding to a circumferential direction of the body part; and the first fiber reinforced resin member and the cap are covered as a unit, along an axial direction of the body part, with a second fiber reinforced resin member having a fiber direction corresponding to the axial direction of the body part.

3 . The high-pressure container according to claim 2 , wherein:
the cap is generally in a shape of a semicircular column that is rounded outward in axial directions of the body parts; and the second fiber reinforced resin member covers the cap along an are of an outer circumferential surface of the cap.

4 . The high-pressure container according to claim 1 , wherein the cap is provided with a valve member that controls an amount of a fluid flowing in the communication channel.

5 . A method of producing a high-pressure container including a plurality of body parts arranged side by side, each of the body parts having a cylindrical shape and having an opening at at least one of axially opposite end portions of the body part, a cap configured to close the openings of the body parts as a unit, and a communication channel provided inside the cap and configured to communicate interiors of the body parts with each other, the method comprising:
a first step of winding a first fiber reinforced resin member on each of the body parts, along a circumferential direction of the body part, the first fiber reinforced resin member having a fiber direction corresponding to the circumferential direction of the body part; and a second step of integrally winding a second fiber reinforced resin member on each of the body parts and the cap along an axial direction of the body part, the second fiber reinforced resin member having a fiber direction corresponding to the axial direction of the body part.

6 . The method according to claim 5 , wherein:
the cap is formed generally in a shape of a semicircular column that is rounded outward in axial directions of the body parts; and the second fiber reinforced resin member is wound along an arc of an outer circumferential surface of the cap.
