A closure lid for wall openings consists of a lid (4) removably set into a wall opening (2). When the lid (4) is set into the opening (2), its edge closely follows the edge of the opening and is flush with the surface of the wall that surrounds the edge of the opening. In part of the circumference of the lid, the marginal surface (11) of the lid (4) slants outwards from the front (12) to the back (13) of the lid. In at least part of the remaining circumference of the lid, its marginal surface (11) slants inwards from the front (12) to the back (13) of the lid (4). The marginal surface (17) of the opening (2) is substantially parallel to the marginal surface (11) of the lid (4). When the lid (4) has an approximately rectangular outline, the marginal surface (11) of the lid (4) slants outwards from the front (12) to the back (13) of the lid along one side (7) of the rectangle formed by the lid (4), and along both sides (8, 9) of the rectangle adjacent to the above-mentioned side (7) it slants inwards from the front to the back of the lid (4).

Un couvercle de fermeture d'ouvertures ménagées dans des parois est constitué d'un couvercle amovible (4) de fermeture d'une ouverture (2) ménagée dans une paroi. Lorsque le couvercle (4) est posé sur l'ouverture, le bord du couvercle (4) suit étroitement le bord de l'ouverture et affleure la surface de la paroi qui entoure le bord de l'ouverture. Sur une partie de la circonférence du couvercle, la surface marginale (11) du couvercle est évasée de la face antérieure (12) à la face postérieure (13) du couvercle. Dans au moins une partie du reste de la circonférence du couvercle, cette surface marginale (11) se resserre de la face antérieure (12) à la surface postérieure (13) du couvercle (4). La surface marginale (17) de l'ouverture (2) est sensiblement parallèle à la surface marginale (11) du couvercle (4). Lorsque le couvercle (4) présente un contour approximativement rectangulaire, la surface marginale (11) d'un côté (7) du rectangle formé par le couvercle (4) s'évase de la face antérieure (12) à la face postérieure (13) du couvercle, et la surface marginale (11) des deux côtés (8, 9) du rectangle adjacents au côté susmentionné (7) du rectangle formé par le couvercle se resserre de la face antérieure à la face postérieure du couvercle.
