A method of manufacturing a hot-fill container (1) by means of blow molding a preform (16) provided with a wall and a closed bottom (19), said method comprising the steps of: − heating the preform (16) at a temperature greater than the glass transition temperature of the plastic; − introducing the such heated preform (16) within a mold (32) provided with a mold base (36) and sidewalls (34A, 34B), which sidewalls are heated at a predetermined temperature; − blow molding the preform (16) to form the container (1) for subsequent hot-fill applications; wherein: − the wall of said preform (16) has a lower end segment (24) of increased thickness and the bottom (19) has a thickness lower than the lower end segment (24), − the preform (16) is subjected to a length stretch ratio comprised between 3.4 and 3.9, and a hoop stretch ratio comprised between 3.5 and 3.9. |
