ABSTRACT:
An adapter is provided for connecting a dome-shaped high pressure butane gas container and a portable gas stove, the adapter comprising: a connecting body having a first opening, a gas delivery passage extending from the opening, a gas volume controller, and a nozzle body; a pressing member inserted in the first opening, and having a gas flow hole and a groove for leading gas discharged through the gas outlet into the gas flow hole; a supporting plate rotatably arranged at the lower surface of the connecting body, and having a handle, a plurality of elastic sections having stoppers and claws formed integrally from the elastic sections, and two arc-shaped holes; and a cam arranged inside the elastic sections and fixed to the connecting body by bolts, the cam having a third opening for holding the gas outlet of the high pressure butane gas container, a plurality of protrusions, and two holes for inserting the bolts.
In order to connect or separate the adapter to or from the gas container, the adapter or the gas container itself is not rotated, but the supporting plate alone is rotated within a prescribed angle, so that the adapter can be easily connected or separated to or from the gas container without leakage of gas.
