A method of producing a directly blow-formed container. The method includes subjecting a multilayered parison having an inner surface formed of an olefin resin to direct blow forming, the olefin resin containing (i) an organic bleeding lubricant having a melting point of not higher than 50&#xb0; C. in an amount of 5 to 10% by mass, and (ii) a high silica zeolite having a silica/alumina mole ratio of not less than 80 in an amount of 0.2 to 3.0% by mass.

Container in which inner surface is formed from olefin resin layer

A multilayered structure that includes an olefin resin layer and a gas-barrier layer. An adhesive layer is provided adjoining the olefin resin layer and the gas-barrier layer, the adhesive layer consisting of an acid-modified olefin resin. The acid-modified olefin resin has methyl branches in a number of 10 to 200 per 1000 carbon atoms on a main chain thereof, and has not more than 50 branches that are larger than the methyl groups.

Adhesive for polyolefin and multilayered structure

An adhesive for polyolefin used for an extrusion-formed multilayered structure that includes, at least, a propylene type resin layer and an ethylene type resin layer, the adhesive for polyolefin comprising an olefin resin that has methyl branches at a ratio of 10 to 200 per 1000 carbon atoms on a main chain thereof.

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 package including a container body () containing a fluid content () with leaving a head space (), wherein the container body () has an inner surface () on which ruggedness is formed entirely, the inner surface () with the ruggedness of the container body () is coated with a lubricating liquid () immiscible with the fluid content (), and the lubricating liquid () is present as a coating layer interposed between the inner surface () and the fluid content (), and the lubricating liquid () for forming the coating layer forms a liquid pool () at a periphery of an upper end face of the fluid content () contained in the container body () in a state of being held upright.

Package containing fluid content

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.

Structure having a liquid film and method of producing the same

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.
