Abstract: Based on current observational data, a revised model of spherical homogenous circumstellar shell is offered for an interpretation of visual light minima of stars with the R Coronae Borealis type variability. In this model, a light minimum is connected with the formation of one more shell in addition to the permanent one. The structure of circumstellar environment of a star with the R Coronae Borealis type variability during a visual light minimum and in a quiet state is described. Some principal physical and geometrical parameters of circumstellar shells are presented.
