The present invention is capable of more safely using a variety of gases by preventing a leak of gas by having excellent air tightness with perfect air-tightening even if an expansion coefficient gets high with heat since a valve is connected and fixed by connecting a connector for the connection of the valve with the mouth of a complex container (a container made by winding a glass fiber material). The present invention comprises: a container body (10) of which inside is made of synthetic resin materials, of which outside is covered by a glass fiber material, and of which upper part includes a mouth (11) to be combined with a valve; a main connector (200) screwed with the outer surface of the mouth, and including multiple bolt combination holes (202), formed on the upper surface of a body (201), an embedding chamber (202) to insert the bottom of a valve connector (100) into the inner side part, and an elastic part (205) connected to the embedding chamber, and including a screw thread (206), formed on the inner surface, to have elastic force to be placed on the outer surface of the mouth; and a valve connector (100) combined with the top of the main connector by a bolt (B) to connect the valve, and comprising multiple bolt combination steps (102), formed in an upper corner part of a body (101), a combination part (104) including an O-ring (103) to keep air tightness by forming an O-ring groove (102a) in the bottom of the body, and a valve connection hole (106) including a screw thread to be screwed with a connection unit (31) of a valve body (30) inside the body in order to connect the valve body (30). |
