Abstract
An improved high-pressure gas cylinder is provided, which includes a container and a plug. The container has an air passage which communicates an interior of the container with an exterior of the container. The plug includes a body and a sealing sheet, wherein the body is fixed in the air passage. The body has a hole which communicates with the interior of the container, and the sealing sheet covers the hole. The body and the sealing sheet are integral. Whereby, the plug is able to tightly seal the container to reduce the possibility of wasting gas; additionally, the manufacturing process would be less complicated and efficient with the simplified plug.

A method of manufacturing a high-pressure container, comprising:
- holding a container having an opening surrounded by a wall, the opening being in communication with an interior of the container;
- clutching a plug having a body and a sealing sheet;
- injecting a gas into the interior of the container through the opening of the container;
- pushing the plug into the opening of the container;
- and
- moving the plug toward the interior of the container, while simultaneously deforming the wall surrounding the opening of the container to abut against the body of the plug.
A method of manufacturing a high-pressure gas cylinder, comprising:
- holding a cylinder having an opening surrounded by a wall, the opening being in communication with an interior of the cylinder;
- clutching, by a pressing member, a plug having a body and a sealing sheet;
- injecting a gas into the interior of the cylinder through the opening of the cylinder;
- moving the pressing member toward the cylinder to push the plug into the opening of the cylinder;
- and
- moving the pressing member to simultaneously move the plug toward the interior of the cylinder and deform the wall surrounding the opening of the cylinder so that the wall is bent to abut against the body of the plug.
A method of manufacturing a gas cylinder, comprising:
- holding, by a holding member, a cylinder in a chamber, the cylinder being held by the holding member at a bottom of the cylinder, the cylinder having an interior in communication with an exterior of the cylinder via an opening of the cylinder, the opening being surrounded by a wall of the cylinder;
- clutching, by a pressing member, a plug having a top surface, a bottom surface, and a sealing sheet forming at least part of the top surface, the top surface and the bottom surface being configured at opposite ends of the plug;
- injecting a gas, via an intake pipe, into interior of the cylinder;
- and
- pushing, by the pressing member, the bottom surface of the plug into the opening of the cylinder, while simultaneously deforming, by the pressing member, the wall surrounding the opening of the cylinder to abut against the plug.
