A core structure (10) is disclosed for making a preform with an integral hollow handle. The core structure includes an elongate body (12) from which two retractable elements (26, 28) protrude. The mechanism for retracting and extending the elements (26, 28) is within the body (12) and is operated by members (32, 34) which protrude from one end of the body (12). The preform produced by the core structure, and the bottle blown from the preform, are also disclosed. |
