Apparatus including a forming anvil device for insertion into an end closure region of a partially formed container, the anvil device comprising a front edge region, a rear edge region, respective lateral edge regions extending between the front and rear edge regions and first and second forming portions each having a corner-forming zone including at the respective rear edge region and a lateral edge region arranged substantially orthogonal to each other, each lateral edge region, extending away from the corner-forming zone and towards the front edge region, also including an obliquely inwardly arranged portion. Also disclosed are apparatus for forming a bend in a packaging laminate about a boundary zone free from a pre-formed line of weakness and apparatus comprising a pressing device comprising an outermost pressing surface and connected to an arm member rotatable about an axis whereby rotating the arm member rotates the outermost pressing surface about the axis, wherein the outermost pressing surface is arranged at an oblique angle relative to the axis. Aspects of the partially formed container are also disclosed.
