摘要： A container (1) having a body and a rim (3) defining an opening for the container, the container being made of a material such as PET or PEN, is manufactured in a two-stage process. The first stage comprises injection moulding a preform (15) which has a rim (3) formed at its mouth and a continuous body-forming portion (32) extending across the preform from the inner periphery (19) of the rim, the rim having an outwardly-directed extent and including a downwardly-extending portion (21) spaced outwardly from the inner periphery and an outwardly-extending portion (5,6,29) located outwardly of the downwardlyextending portion. In the second stage the preform is placed in a moulding cavity (56) of a blow moulding apparatus (7) at an elevated temperature with the preform being located by means of the rim (3). The body-forming portion expands in the cavity to form the container side wall (20) and bottom wall (2). The upper region (18)of the side wall contacts the downwardly-extending portion (21) of the rim such as to form a box section (25). The side wall (20) has at its upper side region a step (23) above which the diameter of the cavity is substantially equal to or approaches the diameter of the downwardly-extending portion (21) of the rim. Below the step (23) the diameter is less than the diameter of the inner periphery of the rim and tapers therefrom inward downwardly to the bottom wall (2) at an acute angle, whereby the containers can internest.

摘要： A container is made in two stages from material such as thermoplastics that is deformable when heated. 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. On or in the surface of the rim facing away from the body there is a formation such as a spiral rib (5) or groove. In the second stage the still heated preform (1) is blow moulded, possibly with some preliminary mechanical stretching, with the blow pin (9) seated in the open end of the body (2) and the preform held by the outer part (7) of its rim. The wall of the body (2) is expanded and the inner part (4) of the rim is urged away from the blow pin (9), deforming into a short tubular mouth with the formation (5) facing inwards. A spiral becomes a screw thread for receiving a screw-in cover.

In the second stage the still heated preform (1) is blow moulded, possibly with some preliminary mechanical stretching, the blow pin being applied to the open end. The closed end of the body is stretched over a multi-part section (7, 8) of the mould which shapes the base of the container into an indent with an undercut formation, the cross section being generally omega-shaped. The multi-part mould section has a central tapered core (8) surrounded by an array of segments (7), the core (8) being fully inserted to spread the segments (7) for moulding, and being retracted to allow the segments (7) to close up and release the container after moulding. The divisions (12) between segments (7) produce ribs in the indent which provide added strength.

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.
