Integrated device for opening and closing cans with deformation-resistant can lids

An integrated device for opening and closing of cans and tins with a non-deformable partial lid to allow partial emptying of its contents with subsequent closing of a container, with a partial lid detachable as an integrated part of a container's lid, of this container, delimited the partial lid by a circumscribing scoring line and with a lever for the detachment of the partial lid joint together with the lid by centered riveting, wherein the lever comprises a riveting end that comprises a surface of the centered riveting in the same piece, provided with a tear-off extension of the lever and presenting a fold towards the lid, while that the opposite end includes of a handgrip with an upper covering of the partial lid, wherein the opposite end and the rest of the body of the lever are joined together to the surface of the lid of the container by centered riveting, and the lever comprises a connection between the riveting end and the opposite end of the handgrip in a lengthways manner, of the same piece in shape of two non-deformable lateral crosspieces before the applied force tearing off the partial lid as they form longitudinal coating braces for reinforcement, with a die-cut in them, forming transverse folding shafts at their ends connected with the end of the handgrip, and with a partial lid including two connections towards the lid of the container and comprising a non-deformable surface.
