A resin structure comprising a resin formed body () and a liquid layer () formed on a surface of the resin formed body (), the liquid layer () having liquid protrusions () that are locally protruded on the surface thereof. The structure exhibits improved properties on the surface of the resin formed body (), such as improved sliding property and non-adhesiveness to various substances maintaining stability as a result of forming the liquid layer ().

Resin structure having a liquid layer on the surface thereof

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 structure forming a gel-like coating () on a surface of a base material () that is formed in a predetermined shape, the gel-like coating including fine solid particles of a grain size of not more than 50 &#x3bc;m and an oily liquid.

Structure having a gel-like coating on the surface thereof

A packing container featuring markedly improved slipping property and non-adhering property for its contents. In the packing container filled with a content (), at least part of the surface that comes in contact with the content () is a liquid-permeable surface () which holds a lubricating liquid () different from the content ().

Packing container having excellent slipping property for the content

A method of filling a container () with a liquid content (), by ejecting a multilayer filler that includes a core layer of the fluid content and an outermost layer of a liquid while forming a film of the liquid between the inner wall of the container and the liquid content.

Method of filling liquid content and packing container filled with liquid content

A structure including a formed body () and solid particles () distributed on a surface of the formed body () by being externally added thereto, wherein the solid particles () are held on the surface of the formed body () in a form of being covered with a very small amount of an oily liquid (), and an air layer () is present in gaps among the solid particles () that are close to the surface of the formed body ().

Structure having solid particles distributed on the surfaces thereof

A container for containing fluid substance as a content, wherein a container surface that comes in contact with the content is formed of a resin composition that contains a forming-resin and an immiscible-liquid that is immiscible with the fluid substance. The container has markedly improved slipping property for the fluid contents and can be easily produced.

Container having excellent slipping property for fluid contents

A structured body including: a formed body, the surface of which being formed of an underlying resin layer (); and fine particles distributed on the underlying resin layer () on the surface of the formed body, wherein the structured body is characterized in that wax () is distributed on the surface of the underlying resin layer () together with fine particles (), and the wax () is partly absorbed into the underlying resin layer ().

Structured body having hydrophobic surface, and method for producing the same

A hollow molded container of the present invention has a resin layer forming its inner surface, and droplets of an oily liquid are distributed on the surface of the resin layer. In the hollow molded container, slipperiness to a less flowable liquid is enhanced remarkably and the slipperiness is exhibited for a long period of time.

Hollow molded article having excellent aqueous liquid slipperiness

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

A package for low temperature storage includes a container accommodating fluid contents, and is stored under a low temperature environment at 10&#xb0; C. or lower. A lubricating layer derived from a slip improving agent is formed on the inner surface of the container. The fluid contents are in contact with the lubricating layer. When the storage environment temperature of the package is t&#xb0; C. and the cloud point of the slip improving agent is c&#xb0; C., the following condition: t&#x3c;c+30 is satisfied.

Package for storage under low temperature environment and method using same

A resin formed bodyhaving a surface in which hydrophobic fine particlesare distributed, the hydrophobic fine particles having a BET specific surface area of not less than 300 m/g. Despite the hydrophobic fine particles are added in a small amount, the resin formed body exhibits a high water-sliding property and can be used also in the form of a film and a bottle.

Resin formed body having surface that exhibits excellent water-sliding property

A structure forming, on a surface thereof, a rough surface portionhaving a maximum height of roughness Rz in a range of 0.5 to 5.0 &#x3bc;m, and forming, on the rough surface portion, a thin liquid filmhaving a thickness in a range of not less than 0.1 &#x3bc;m but less than 3.4 &#x3bc;m. The structure exhibits a high degree of slipping property despite the liquid film formed on the surface has a very small thickness.

Structure having liquid film on the surface thereof

A pouring fitting having a flow passage for flowing fluid substance, wherein said flow passage is forming a liquid-permeable surfacein at least the tip portion thereof that serves as a pouring port. The pouring fitting has markedly improved slipping property and non-adhering property for liquid or paste-like fluid substances.
