A mould (2, fig 1) for producing injection moulded in-mould labelled plastic containers is provided. The mould comprises: a rim moulding portion (12, fig 1) for use in moulding at least part of a rim of a plastic container; core part 10 includes a surface 14, for use in moulding a wall of the plastic container, having first and second elongate protrusions 21, 22 defining a major channel 31 therebetween; and at least one flow restricting protrusion 41, located in or for location in an interface region of the major channel and the rim moulding portion, for dividing the major channel into a multiplicity of minor channels in the interface region and for restricting the flow of plastic towards the rim moulding portion. The first and second elongate protrusions may be shaped, in the interface region, to cause plastic flowing in the interface region to spread across a greater distance in the interface region than the width of the major channel. When the plastic travels along the wall portion (7, fig 1) of the cavity (11, fig 1), the label (6, fig 1) adheres to the molten plastic and, when the plastic cools and solidifies, the label becomes integrated into the wall of the plastic container as it is formed. |
