ABSTRACT:
A packed electric lamp including a carton having three articulated sides defining a sleeve of triangular cross-section with opposing open ends and two opposing triangular flaps closing the open ends of the triangular sleeve. A reflector lamp having a broad face and a tapered reflector body is arranged in the carton with its broad face extending along one of the three sides defining the triangular sleeve, the other two carton sides defining the triangular sleeve extending along the tapered body and terminating at a corner of the sleeve adjacent the distal end of the reflector body. The carton has a significantly smaller plan form than rectangular or square cuboidal cartons, allowing more lamps to fit in a given space on retail shelves. The carton is formed from a unitary blank having three rectangular panels joined at fold lines and first and second opposing primary triangular flaps articulated from respective ones of the rectangular panels. The corners of the opposing triangular sides may be truncated to further reduce the planform of the carton and lamp packed therein.
