<p>A preform (P) of a jug is injection moulded to have a rim (5, 15) at the mouth of a cupped or tubular portion (1) and a handle (7, 17) with one end free projecting from the rim (5, 15). The preform is transferred to a blow mould which allows the free end (9, 19) of the handle (7, 17) to project into the cavity. On blow moulding, the rim (5, 15) and handle (7, 17) are held, while the remainder of the preform (P) expands to the final jug shape, meeting and welding to the free end (9, 19) of the handle to make that a closed loop with the side of the jug.</p> |
