摘要

Filing structure used primarily for drilled papers, comprising a cover element made of a sheet material or thin sheet but relatively rigid, however, and foldable, and a rigid, elongated bar, the cover element having a flange or flange that is projects in its longitudinal direction, flange which is formed by folding the material, suitably presenting the shape of a t, and said bar being provided with an elongated, open slot, practically of the same section as the flange or flange, so that this flange can be inserted laterally into the groove of the bar and thereby fasten the cover element to the bar in a direction perpendicular to the direction of insertion, characterized by said structure because the fold or fold lines intended to constitute the flange remain located at such a distance from one of the edges of the cover element, that from said flange a, a first portion, which defines the side or back of the archival structure, and a second portion defining the front side or face or a part thereof, the archival structure projects.
