Improved structural shape made from a substantially rigid material, for refrigerator cabinets and the like, provided with a tight-sealing gasket made from a substantially soft material

The present invention relates to a structural shape (1) made from a substantially rigid material for refrigerator cabinets and the like, in which the door (30) of the cabinet comprises a counter-door (31), with said structural shape (1) bearing a tubular bellows-like acting gasket (20) made from a substantially soft material, which accomplishes a tight sealing between the door (30) and the case (17) of said cabinet, with the structural shape (1) and the gasket (20) being suitably coupled with each other, or manufactured as one single piece by means of the co-extrusion of said substantially rigid and said substantially soft materials, with said structural shape (1) being provided with at least one side, elastically yielding flange (7) which acts as a spring in order to accomplish a snap-coupling with the counter-door (31) during the step of components assemblage, characterized in that in said side flange (7) the fulcrum (8) of the spring is constituted by an elbow-insert of said substantially soft material formed in the substantially rigid material the structural shape (1) is made from.
