ABSTRACT:
To retain an electric lamp in position within the box, in which the elect lamp has a base with projecting terminal pins (21), in such a manner that the pins (21) cannot push through and extend from the box. The box is formed with dust flaps (10, 11) which are folded inwardly to form an essentially triangular, inwardly extended projection or bridge. The so folded dust flaps (10, 11) are formed at their free ends with interengaging teeth and recesses, the interengaging apex of the triangular support structure engaging against the base (20a) of the lamp and forming a corner with one of the sidewalls (3) in which the pins (21) from the lamp (20) can fit, while the lamp itself is securely retained in immovable position of the box. The angle of the dust flaps (10, 11) with respect to the adjacent sidewalls (1, 3) can suitably vary within about 45 and 70 degrees.
