We investigate the vacuum and charged spherically symmetric static solutions of the Einstein equations on cosmological background. The background metric is not flat, but curved, with constant - curvature spatial sections. Both vacuum and charged cases contain two branches. The first branches transform into the Schwarzschild and Reissner-Nordstr"om solutions if the background metric goes to the Minkovski one. The second branches describe wormholes and have no Einstein limit.
