Pressurized gas injecting device (14) for a machine (1) for blow molding or stretch blow molding a container from a blank (2) of plastic material. The device has a nozzle (15) movable between an upper position separated from a mold (9) intended to receive the blank (2) and a lower position pressed against the mold (9) while covering a neck (3) of the blank (2); an insert (36) mounted movably with respect to the nozzle (15), the insert (36) having a lower end face (45) capable of being pressed against a lip (4) of the blank (2); and a return device (44) applying force on the insert (36) toward a lower position in which the insert (36) is at the end-of-travel stop with respect to the nozzle (15), and in which the lower end face (45) of the insert (36) extends beyond the nozzle (15). |
