A multilayered structure having a liquid layer () on a surface of a plastic underlying layer (), wherein a liquid diffusion prevention layer () is provided on the lower side of the underlying layer () to suppress or block a diffusion of a liquid that forms the liquid layer (), and a covering ratio F of the liquid layer () is maintained to be not less than 0.5. With this structure, the surface properties of the liquid layer () can be stably maintained over long periods of time.

Multilayered structure having a liquid layer on the surface thereof

A pour-out member or, for example, a container has a pour-out portthrough which a viscous fluid is discharged, wherein a hydrophobic layer of fine hydrophobic inorganic particlesis selectively formed on an upper end surface of a base member forming the pour-out port. The hydrophobic layer formed on the pour-out portof the pour-out member is not removed or broken through the repetitive use, and stably exhibits a function of preventing the liquid from creeping over extended periods of time.
