A combined drain back, spout and plastic container includes a plastic container having a body and a finish. The finish has an axial portion and an internal annular land. A drain back spout comprising an outer annular wall and an integral spout connected to the outer wall and the outer annular wall of the spout and the container are spin welded along the annular land. The annular land is machined before spin welding. A method of making a combined drain back, spout and plastic container includes forming a plastic container having a body and a finish having an axial portion, a first internal annular land and a second annular land on the axial portion of the finish. The drain back spout is formed with an outer annular wall and an integral spout connected to the wall. The spout is inserted such that the annular wall of the spout and the container are in contact along the annular land and then the spout is spin welded to the finish along the annular lug. Preferably, the annular land is machined before insertion and spin welding.

Le talon annulaire est usiné avant le soudage par rotation. Une méthode de fabrication d'un contenant en plastique combiné à un bec de vidange consiste à former un contenant en plastique doté d'un corps et d'un fini ayant une portion axiale, un premier talon annulaire interne et un second talon annulaire externe sur la portion axiale du fini. Le bec de vidange comporte une paroi annulaire externe et un bec intégré raccordé à la paroi. Le bec est inséré de manière que sa paroi annulaire et le contenant soient en contact le long du talon annulaire, et il est ensuite soudé par rotation au fini le long de la patte annulaire. Le talon annulaire est de préférence usiné avant son insertion et le soudage par rotation.
