  We explore equilibrium solutions of non-topological solitons in a general
class of scalar field theories which include global U(1) symmetry. We find new
types of solutions, tube-shaped and crust-shaped objects, and investigate their
stability. Like Q-balls, the new solitons can exist in supersymmetric
extensions of the Standard Model, which may responsible for baryon asymmetry
and dark matter. Therefore, observational signals of the new solitons would
give us more informations on the early universe and supersymmetric theories.
