Abstract

The present invention relates to a door device for a container, which is preferably cylindrical, comprising at least one casing portion with an opening provided in that portion. Device characterised in that it consists principally, on the one hand, of two hollow rectilinear profiles (4 and 4') parallel to each other, fixed or formed on the external face of the casing on both sides of the opening and each containing a longitudinal opening in the form of a slot and, on the other hand, of at least one element in the form of a plate (5, 5') having at rest a curvature resembling that of the casing portion (2') containing the opening and comprising two opposite parallel edges (6 and 6') each provided with a profiled longitudinal thickening, of which the section causes retention in one of said hollow profiles (4, 4') and allows sliding therein, these hollow profiles (4, 4') thus forming positive connection means and slide rails for said element(s) (5, 5') in the form of (a) plate(s) and guiding it (them) between a closed position of the opening and a disengaged or released position thereof.
