Disclosed is a connection device to be coupled with a container neck in different standards for use. The connection device is formed with a mouth part at the upper side and a screw thread part at the lower side. The mouth part at the upper portion of the connection device is formed in a screw thread or other shape in the standard corresponding to a bottle lid, and the inside of the screw thread part is formed with a screw thread corresponding to the standard of the container neck. The screw thread is integrally formed or an elastic screw thread is additionally added for the coupling with the necks of a plurality of containers.
