ABSTRACT:
A container is made by folding a blank to define a receptacle, clamping the blank between a core tool and a cavity tool and seaming juxtaposed blank edges by injection moulding, one tool defining a recess overlying the juxtaposed edges and at least one preferred flow path being defined in that recess offset relative to the juxtaposed edges so that injected material clamps the edge region over which the preferred flow path lies against the other tool face opposite the recess to prevent injected material penetrating between the blank over which the preferred flow path lies and that other tool face.
