Abstract: An assembly of a container (1) and a child resistant closure (5) therefor. The container (1) has an external bead (3) on the neck (2) thereof and the closure (5) an inturned flange (8) on the skirt (7) thereof which makes snap engagement with the bead (3). The neck (2) of the container (1) comprises an external screw thread (4) while the skirt (7) of the closure (5) is locally severed or weakened to provide local deformable skirt portions (11) which can be deformed inwards by finger pressure thereon to enage thread portions (13) on the skirt portions (11) with the screw thread (4). The closure (5) is removable from the container (1) by deforming the skirt portions (11) to engage the thread portions (13) with the screw thread (4) by finger pressure thereon and rotating the closure (5) relative to the container (1) while maintaining said finger pressure.
Abstract: The invention provides a method of and apparatus for cooling the core rods of an injection blow moulding machine having stripper means and an injection blow moulding machine incorporating the cooling apparatus of the invention. The apparatus of the invention comprises nozzle means, preferably in the form of a hollow nozzle bar the interior of which is connectable to a source of cooling fluid under pressure, separate from the stripper means and comprising a plurality of nozzles which are movable between an out-of-use position and an in-use position in which they are interposed between the core rods and stripper means for directing cooling fluid onto the tips of the core rods and preferably substantially axially of the core rods.
