To provide a laminate for a rondelle molding which has good followability to deep draw molding, is prevented from generating delamination and a pinhole, and is excellent in moldability, to produce the rondelle molding which is excellent in gas-barrier properties and openability during the sticking opening of a sealed spout, and to provide a tube container using it.
The laminate for the rondelle molding is composed of a shoulder part in the shape of a truncated cone, a cylindrical head part connected to the shoulder part, and a sealed spout which can be broken by a protuberance. The laminate is composed of at least an unstretched thermoplastic resin layer, a metal foil protective layer, a metal foil layer, and an adhesive resin layer, and a thermoplastic resin layer which are arranged in turn from the outside. The rondelle molding is produced by deep draw-molding the laminate.
