A method for blow moulding a bottle 5 having a neck 2 comprises closing a mould around a parison of thermoplastics material, penetrating the parison with a blow pin 1 and, inflating the parison against the walls of the mould to form a bottle 5 having a neck 2, a longitudinal axis of the blow pin 1 being aligned with a longitudinal axis through the neck 2 of the bottle 5. The blow pin 1 has a leading face 3 which is substantially flat and the method comprises advancing the blow pin 1 to press the flat face 3 of the blow pin 1 against the base wall region 4 of the bottle 5 opposite to the neck 2.
