High pressure container

1. A high pressure container comprising:

a plurality of container bodies, each of the container bodies housing a fluid in a high pressure state and being able to release the fluid through a release portion;

an opening section that is linked to the container bodies, and that opens at or above a predetermined opening temperature to release the fluid inside the container bodies; and

a cover member that straddles the plurality of container bodies, that covers at least a portion of the plurality of container bodies, that is able to withstand a temperature of no less than the opening temperature, that is linked to the opening section, and that is capable of transmitting heat to the opening section,

wherein a thermal conductivity of the cover member is higher than a thermal conductivity at a surface of the container bodies, and

wherein the opening section includes a fusible plug including a cylinder body and a plug provided inside the cylinder body, the plug being formed from a metal having a melting temperature which is less than or equal to the predetermined opening temperature.

2. The high pressure container of claim 1 , wherein the cover member is larger than the plurality of container bodies as viewed along a direction in which the cover member and the plurality of container bodies face each other.

3. The high pressure container of claim 1 , wherein the cover member is capable of housing the plurality of container bodies inside the cover member, and the plurality of container bodies are covered by the cover member from a plurality of directions by being housed inside the cover member.

4. The high pressure container of claim 1 , further comprising a low thermal conductivity layer that is provided between the cover member and the plurality of container bodies, and that has lower thermal conductivity than the cover member.

5. The high pressure container of claim 4 , wherein the low thermal conductivity layer is configured by a layer of air.

6. The high pressure container of claim 1 , wherein the plurality of container bodies are linked through a communicating section so as to be in communication with each other.

7. The high pressure container of claim 6 , wherein:

the communicating section includes a single passageway that is linked to all of the container bodies and through which the fluid that has left the container bodies passes; and

the opening section is provided to the passageway.

8. The high pressure container of claim 1 , wherein a plurality of opening sections are provided corresponding to each of the release portions of the plurality of container bodies.

9. The high pressure container of claim 1 , wherein the plurality of container bodies are disposed alongside one another in a row along a vehicle width direction or are disposed alongside one another in a row along a vehicle front-rear direction at a vehicle lower side of a floor section of a vehicle, and the cover member is provided at least at a lower side of the plurality of container bodies.

10. The high pressure container of claim 1 , wherein the cover member includes a bottom wall presenting a substantially rectangular plate shape in plan view, and a peripheral wall provided above the bottom wall, the peripheral wall including an inner plate, an outer plate, and a horizontal plate provided between the inner plate and the outer plate, and

wherein the plurality of container bodies are disposed above and spaced apart from the bottom wall.

11. The high pressure container of claim 10 , wherein each of the container bodies includes a casing body, a first cap at a first end of the casing body, and a second cap at a second end of the casing body,

wherein a first manifold includes plural first connectors connected to the first caps of the plurality of container bodies, the plural first connectors being supported by plural first attachment brackets provided on the bottom wall, and

wherein a second manifold includes plural second connectors connected to the second caps of the plurality of container bodies, the plural second connectors being supported by plural second attachment brackets provided on the bottom wall.

12. The high pressure container of claim 11 , wherein the second manifold includes a tube having a first end coupled to one of the plural second connectors and a second end coupled to a valve, the tube passing through a hole provided on the peripheral wall.
