PURPOSE:To prevent the damage of other hollow container in a process transporting or moving a hollow container even when the scar of a seal part is left as it is and to enhance production efficiency by simplifying a process producing the hollow container by the blow molding of a thermoplastic resin to a large extent. CONSTITUTION:In a hollow container 1 made of a thermoplastic resin and having a mouth part 4 formed to one end of a body part 2 thereof, an expanded head part 5 is further integrally formed to the upper end of the mouth part 4. A recessed groove 8 is formed to the upper end of the head part 5 and a thermally melted seal part 9 wherein a protruding communication part introducing a pressure fluid for blow molding is melted and sealed under heating is formed in the recessed groove 8. |
