ABSTRACT:
A container is made in two stages from thermoplastics material. In the first stage a preform (1) is injection moulded, the mould parts easily releasing a tubular body (2) with a closed end and an outwardly projecting rim (3) at the open end. In the second stage the still heated preform (1) is blow moulded, possibly with some preliminary mechanical stretching, with the blow pin (13) seated in the open end of the body (2) and the preform (1) held by the other part (7) of its rim. The wall of the body (2) is expanded, and immediately below the open end it is stretched outwardly to meld with the underside of the inner part (5) of the rim. The resultant container thus has a mouth defined by an inset lip. It may be of paint tin form, with a drip groove (9) around the mouth.
