ABSTRACT:
The curved pack end flap (20) of the present invention can generally be used in any pack that has a surface that is curved inwards. The curved pack end flap (20) incorporates multiple panels (27) interconnected at points (30) other than the folding edge (51) to provide for the deformation of the end flap when the surface, from which the curved pack end flap (20) is attached, is curved inwards during the formation of the pack. The folded curved pack end flap is subsequently affixed to a second surface in the formation of the pack. The curved pack end flap (20) with the interconnected panels (27) functions to maintain positional accuracy, decrease tearing of the end flap panels (27) during the folding process, and allow for glue application to be more precise during assembly as compared to the end flap of the prior art.
