Abstract: A thin flat strip of laminated material is directed through a die which forms it into a tubular member. The longitudinal margins of the tubular member are overlapped and sealed together. Thereafter, the tube is severed from the strip and fed on to a spindle extending outwardly from the face of a rotatable plate. The plate is then rotated through a series of stations in which the outer end of the tube is precisely formed with a series of equally spaced flutes, the flutes are twisted to produce a neck and shoulder configuration, an outsert having the shape of the neck and shoulder of a collapsible container is slipped upon the twisted portion of the tube and sealed thereto and a closure cap is threaded upon the outsert neck. The completed container is then unloaded from the spindle.
