ABSTRACT OF THE DISCLOSURE A hollow plastic container is formed from at least two separately molded adjacent portions of thermoplastic material, each portion being hollow and having an inner surface, an outer surface and a continuous end surface abutting a corresponding continuous end surface of the adjacent portion. Each end sur- face has a key groove extending axially inwardly therefrom continuously therearound, and the key grooves in the adjacent portions cooperate to provide a jointing groove when the portions are held in assembled relationship. The container has a continuous opening extending inwardly from the outer surface of at least one portion and continuously around the periphery thereof and communicating with the jointing groove, the opening being narrower in the axial direction than the axial length of the jointing groove. A thermoplastic molding material of substantially the same material as the plastic material adjacent portions fills the jointing groove and the opening, the molding material being bonded to the two adjacent- portions to rigidly connect and form a fluidtight seal between the two adjacent portions.
