A spray vessel including a body of engineering plastic having a cylindrical shape to hold a content to be injected and a coupling part on its upper side end along its outer circumference; and a nozzle assembly of engineering plastic having a coupling part on its outer circumference to mate with the coupling part of the body. The coupling parts are joined to each other by a spin welding process such that the body is integrally formed with the nozzle assembly. A method of manufacturing such a spray vessel by injection molding and spin welding assures excellent pressure resistance and productivity. |
