A container blow molded from a polymeric material, which is configured to store a hot-fill product. A first wall extends from a standing ring to a diaphragm of a base. A first hinge is at a first interface between the first wall and the standing ring. A second hinge is at a second interface between a second wall and a third wall extending to a center portion. In response to a vacuum generated within the container as the hot-fill product cools subsequent to filling and capping the container, the base is configured to move inward from an as-blown configuration to an activated configuration to absorb the vacuum by flexing at the first hinge and the second hinge. In the activated configuration, the center portion, the second wall, the third wall, and the second hinge are closer to the finish than in the as blown configuration.

A container treatment system includes a production machine for preforms, a blow molding machine and at least one heat exchange device. The production machine and the blow molding machine are interlocked with one another, and the at least one heat exchange device is configured for heat exchange between the production machine and at least one component of the container treatment system.

A container treatment system includes a manufacturing machine for preforms, a blow molding machine, and at least one heat recovery device. A first process medium can be supplied from the manufacturing machine and/or the blow molding machine to a first heat recovery device. Heat can be exchanged between the first process medium and a second process medium of the container treatment system using the first heat recovery device.

The injection-blow-moulding mould comprises: a punch (1) having a blow opening (3) connected to a first conduit (5) which is in communication with a first source of pressurised gas supply (6) configured to supply pressurised gas through the blow opening (3) at an overpressure (OP) above a blowing pressure (BP) suitable to blow a preform (30a) into a container (30b) and an exhaust opening (4) connected to a second conduit (7) which is in communication with a pressure-limiting device set at the blowing pressure (BP); a blow-moulding cavity (2) configured to receive therein the punch (1) with a hot and soft preform (30a) arranged thereon; and a cooling device associated to the blow-moulding cavity (2). Gas inside the container (30b) exceeding the blowing pressure (BP) is allowed to escape through the exhaust opening (4) thereby a cooling gas stream is created from the blow opening (3) to the exhaust opening.
