Abstract

A structure ( 10 ) includes a formed body ( 1 ) of a predetermined shape and a liquid film ( 3 ) formed on the surface thereof, the liquid film ( 3 ) being formed by using a dispersion solution obtained by dispersing, in a dispersion medium, a liquid that is incompatible therewith. The structure ( 10 ) exhibits slipping property to the emulsified product maintaining stability. Also disclosed is a method for producing the structure.

First claim

The invention claimed is:

1. A method of producing a structure that includes a container and a liquid film formed on a surface thereof, the method comprising steps of:
preparing a dispersion solution by dispersing, in a dispersion medium, a liquid that is incompatible therewith; and
forming the liquid film of said dispersion solution by applying said dispersion solution onto the surface of said formed body before said dispersion medium and the liquid incompatible therewith separate away into liquid phases.

2. The method of production according to claim 1 , wherein the container is filled with a content after the step of forming said liquid film but before the dispersion medium and the liquid incompatible therewith in said liquid film separate away into liquid phases.

3. A structure that includes a container, a liquid film formed on the inner surface of the container, and a content contained therein so as to come in contact with said liquid film,
wherein said content is an emulsified product; and
said liquid film comprises a dispersion solution obtained by suspending and dispersing water in an oily liquid that is insoluble in water.

4. The structure according to claim 3 , wherein said liquid film comprises a first liquid film formed on the inner surface of said container and a second liquid film formed on said first liquid film, said first liquid film having a W/O dispersion structure that is rich in oil and contains little water, and said second liquid film having a dispersion structure that is richer in water than said first liquid film.

5. The structure according to claim 3 , wherein said oily liquid that is insoluble in water is an edible oil.
