Abstract

A blank, carton, or package including a handle formed in a top panel is described. Deformation lines can be included on the blank or carton to allow the handle to flex, thereby increasing handle strength. The blank can include corner-forming panels attached to end flaps that can be used to form corners in the formed carton or package. The corners provide reinforcement strength to allow stacking of the cartons or packages, such as on pallets or during shipment. Openings can be provided in select areas of the blank, carton, or package to allow ventilation to and from the interior of the carton or package. Connecting panels in the top panel can be removed to dispense articles from the carton or package.
