A method is provided for forming a recyclable plastic container component with an integral preform. A preform is placed within a mold recess. The mold is closed to capture the preform, thereby forming a flow passage with a shape corresponding to contours of the container component. Plastic is injected into the flow passage under pressure. The injected plastic bonds to an edge portion of the preform. The molded component is then cooled and removed from the mold.

1. A lid for a container, having a flexible lid portion integrally bonded to a rigid portion, wherein a liquid-tight seal is provided between said flexible lid portion and said rigid portion, said container lid joined sealingly with:a substantially flexible premolded spout with a substantially continuous and solid flange extending outwardly from a perimeter of said flexible spout into surface, melt molded sealing contact with said lid, said flexible spout when so joined being moveable between an extended position for pouring out the contents of said container and a retracted position effective to permit stacking of a plurality of said containers; and said lid having a substantially rigid body made of flowable polymeric material integrally pressure surface bonded to said flange of said spout; wherein an edge portion of said flange on said flexible spout is surface melt molded into said rigid body of said lid to form a liquid-tight bond between said surfaces of said flange and said rigid lid body as flowable polymeric fluid comprising said rigid lid body is injection molded to said flange, and as said flowable polymeric material forming said rigid body is forced under pressure into intimate contact with said surfaces of said flange.
