Abstract: A reinforced handle is provided in an end wall closure of a sleeve type carton by forming a handle aperture in a top end flap, and by aligning the handle aperture with corresponding cutouts formed in respective side end flaps, each cutout being reinforced with one or more reinforcing panels that align with at least its weight bearing edge. Each reinforcing panel is hingedly attached to the respective side end flap to be foldable along the hinged connection and secured in a face contacting arrangement, whereby the reinforcing panel overlies the cutout as an overlay panel, or aligns its edge with the weight bearing edge of the cutout. In this manner, the material at the weight bearing edge of the cutout is at least two plies thick. When the carton is fully erected and sealed, the reinforced cutout is in registry with the handle aperture, thereby creating the reinforced handle.
