A combined drain back spout (DBS) fitment and plastic container assembly comprising a plastic container body and finish and a plastic drain back spout fitment having a pour spout connected to a surrounding drain gutter and spill-catching apron. The fitment apron has an integral mounting collar with a radial flange spanning the finish end edge and a collar skirt dependent therefrom and encircling the outer surface of the container finish and being sealably joined thereto by a spin weld joint. The lower free end edge of collar skirt is closely spaced from the juxtaposed surface of the container body, and the collar skirt and finish exterior surface conjointly define an intervening space for receiving, containing and hiding spin weld slag and/or shavings. The finish is corrugated to provide annular external ribs and intervening external grooves to thereby provide sacrificial parent spin weld material in the rib crowns and slag-receiving spaces in the grooves.

[ I claim:] [12.] The method of making a combined drain back spout fitment and plastic container assembly comprising the steps of:(a) forming a plastic container having a body and a fitment finish, said finish comprising a generally radial inwardly extending wall connected to said body and an axially outwardly extending neck wall integral with said radial wall and extending axially outwardly with respect to said body and terminating at an annular free end edge, and(b) forming a one piece plastic drain back spout fitment comprising an annular wall, an integral spout connected to said annular wall, a surrounding apron wall extending radially outwardly and upwardly integrally from said annular wall, and an annular fitment mounting collar having a collar interior wall extending axially upwardly integrally from said apron wall, a collar flange adapted in assembly to span said finish free end and extending radially outwardly integrally from said collar interior wall and a collar exterior skirt wall integrally dependent from said collar flange and constructed to encircle the outer surface of said container finish in assembly therewith for being sealably joined thereto by a spin weld joint,(c) inserting said fitment into said finish, and(d) spin welding the outer surface of said container finish to the inner surface of said collar skirt wall.
