Abstract: Provided is a hard container capable of appropriately discharging or spraying content. The present invention provides a resin-made hard container for use with a suction device attached thereto that is configured to discharge or spray suctioned content. The hard container is provided with a container body having an outer shell and an inner bag. The container body is configured such that the inner bag contracts as the content is reduced. An innermost layer of the outer shell comprises an EVOH layer.

Abstract: Provided is a delamination container that can suppress deformation of container, when a cap is attached thereto, without being provided with a support ring. The delamination container has a container body with an accommodation section for accommodating contents therein and an opening for discharging the contents from the accommodation section. The accommodation section and the opening have an inner layer, which contracts as the contents decrease, and an outer layer. The opening has an engagement section with a cap, which is to be attached to the opening, and a constriction section that constricts toward the inner side of the opening. The opening has an upright wall extending from an outer edge of an upper wall of the constriction section at an angle between 34 degrees and 135 degrees relative to the upper wall. There is an inner layer gap between the upright wall and the upper wall.

Abstract: A delaminatable container is provided that is excellent in all of squeezability, drop breaking resistance, and non-transmittance of water vapor. The present invention provides a delaminatable container, comprising a container body having an outer shell and an inner bag, the inner bag to be shrunk with a decrease in contents, wherein the inner bag is composed of an inner layer including a mixed resin layer formed of a mixed resin containing a cycloolefin polymer and a styrene-based thermoplastic elastomer.

Abstract: Provided is a double container (1) configured so that water entrance through an atmospheric air introduction hole (15) can be reliably prevented and that an adverse effect due to water entrance into an intermediate space (21) between an outer shell (11) and an inner bag (12) can be avoided. The double container (1) has the outer shell (11) and the inner bag (12). The inner bag (12) contracts in association with a decrease in contents housed in the inner bag (12). The outer shell (11) is provided with the air introduction hole (15). Further, a hydrophobic filter configured to allow air penetration and block water is provided to close the air introduction hole (15).

Abstract: Provided is a light-shielding container which has an ultraviolet-ray transmittance of 0% at wavelengths of 200-370 nm and to which contents are less apt to adhere. A light-shielding container for holding contents, characterized by having at least an inner layer composed of a thermoplastic resin, a first light-shielding layer composed of a resin containing an inorganic ultraviolet inhibitor and a second light-shielding layer composed of a resin containing an organic ultraviolet absorber, disposed in this order from the content side.

Abstract: A medical container is formed by blow molding, and subjected to the steam sterilization. The medical container includes: an innermost layer made of a cyclic polyolefin resin; a gas barrier layer located at a position external to the innermost layer and made of an ethylene-vinyl alcohol copolymer resin or the like; and an adhesive layer jointing at least the gas barrier layer to the innermost layer. An adhesive used in the adhesive layer contains maleic anhydride modified polypropylene and styrene elastomer.
