The packaging carton of the packed electric lamp has an incision line through diagonally opposed edges in respective side walls adjoining these edges. Boundary lines extend in each of the two side walls from said incision line to a point P of the edge, which point lies closer to the first end, so as to define together with the incision line a region of said walls which is flipped over as a folded portion into the carton, thus narrowing the carton. The lamp may be readily machine packed into the carton, starting from the back of the carton, and displays essential distinguishing marks of its bulb while the packaging remains closed.

A packed electric lamp comprising: an electric lamp with a light transmitting bulb which has an end portion supporting a lamp cap; a packaging carton around the electric lamp having a substantially rectangular cross-section, the carton having a first pair of mutually opposed side walls and a second pair of mutually opposed side walls, the pairs of side walls being interconnected along edges of the carton formed on folding lines, the carton having a first end near the lamp cap and a second end opposed thereto near the bulb, the carton having an incision line through one of the edges and respective side walls adjoining said edge, boundary lines extending from said incision line in each of the two respective side walls to a point of the edge intersected by the incision line, which point lies closer to the first end, so as to define together with the incision line a region of said side walls which is pivoted into the carton as a folded portion, thus narrowing the carton, the incision line forming an edge of the folded portion, the carton having means near the second end for blocking passage of the lamp, characterized in that: the incision line is present in only two of the edges, and the folded portions pivoted into the carton extend towards the lamp cap of the lamp.
