Abstract

Priscºpio, characterized in that it is constituted by a punched sheet of semirigid material which, having a rectangular configuration, differs in four longitudinal zones of uniformly equal width, of equal length and separated from each other by three fold lines, whose zones, in turn, each one is differentiated into a central subzone and two extreme subzones, these being separated from its central sub-area, in the wide areas by a fold line or by a window, making it alternately that of one wide area with respect to the other. Equal width, while the extreme subzones of the narrow zones are separated from their central sub-area by total cross-sectional cut, with those extreme subzones of fins and complementary ears of openings disposed in the central subzones themselves, so that by bending, along its longitudinal fold lines, a rectangular prism is formed, which is stabilized by adhesion between the opposite free edges of the lateral areas of the sheet, said prism being differentiated in a central prism and two extreme prisms, which, through the fold line that joins them to the central prism, are orthogonally lowered in senses opposites against the central prism to form a tubular body with opposite layered which is stabilized by the coupling between ears, fins and openings and has, in the central and extreme sub-areas of the wide areas, some stamping for the positioning of some specular elements and, on the free edge of the extreme subzone of the wide area forming the lower face of the lower elbow, of a notch.
