The invention relates to a bar-shaped display element (18) which has three rectangular, picture-bearing surfaces (12, 14, 16) positioned as long sides of a body with a cross section in the shape of an equilateral triangle. According to the invention, the display element (18) is produced from a plane, sheet- shaped piece of rigid material which is bent to form a dimensionally stable, hollow body with a cross section in the shape of an equilateral triangle, two of its long sides (12, 16) being fastened to one another by means of at least one fastening flap (22) which is continuous with one long side (16) and is folded in inside the other long side and permanently attached to the inside of the latter. The blank from which the display element (18) is produced suitably consists of corrugated board with an outer plane layer suitable for printing.

La présente invention porte sur un élément (18) d'affichage en forme de latte qui comporte trois surfaces (12,14,16) rectangulaires portant des images situées pour constituer les longs côtés d'un corps dont la section transversale a la forme d'un triangle équilatéral. Selon cette invention, l'élément (18) d'affichage est produit à partir d'une pièce de matériau plane en forme de feuille qui est courbée pour former un corps creux à stabilité dimensionnelle dont la section transversale se présente sous forme d'un triangle équilatéral, deux de ses longs côtés (12,16) étant fixés ensemble au moyen d'un rabat (22) de fixation qui prolonge un long côté (16) et qui est replié à l'intérieur de l'autre long côté et fixé de manière définitive à l'intérieur de ce dernier. L'ébauche à partir de laquelle l'élément (18) d'affichage est produit est judicieusement réalisée en carton ondulé comportant une couche extérieure plane adaptée à l'impression.
