  When a potential for a scalar field has two local minima there arise
spherical shell-type solutions of the classical field equations due to
gravitational attraction. We establish such solutions numerically in a space
which is asymptotically de Sitter. It generically arises when the energy scale
characterizing the scalar field potential is much less than the Planck scale.
It is shown that the mirror image of the shell appears in the other half of the
Penrose diagram. The configuration is smooth everywhere with no physical
singularity.
