Abstract: A rubber plug for a vial container includes a leg portion press molded independently, and having a base end side portion, and a plate-shape cap portion bonded to the base end side portion press-molded with the leg portion. The leg portion and the plate-shape cap portion have bonding areas formed as concentric concavo-convex areas. The base end side portion of the leg portion including the area bonded with the plate-shape cap portion is formed of a material same as that of the plate-shape cap portion. A remaining portion of the leg portion except for the base end side is formed by a material different from the plate-shape cap portion.

Abstract: A sanitary container has a hollow cavity for storing a product in cleanliness. A wall portion of the container has a laminated structure of an inner layer and an outer layer. The outer layer is made of a cyclic olefin polymer containing at least one pigment selected from the group consisting of C.I. Pigment Yellow 147, C.I. Pigment Yellow 180 and C.I. Pigment Yellow 181 and added therein. The inner layer is made of a cyclic olefin polymer free of the at least one pigment. The sanitary container is superb in pigment dispersion (ultraviolet ray blocking property), is free of troublesome contamination of its content with pigment particles, and is also excellent in impact resistance strength, gas barrier properties and interface bonding.

Abstract: A rubber plug for a vial container containing medicinal chemicals according to the present invention can be smoothly conveyed by a part feeder while preventing each other's adhesion. The top surface of a discoid cap portion 1A has a Shore A hardness of 25-55 and a surface roughness Ra of 2.5-10.5 ?m. Adherence of the top surface of the discoid cap portion 1A is reduced by synergy effect. The rubber plug 1 can be smoothly conveyed by a part feeder in an inverted position which turns the top surface of the discoid cap portion to the conveying surface.

Abstract: A syringe needle cap (10) is filled to the tip of the barrel (21) of a prefilled syringe (20). And the tip of a syringe needle (22) is stuck into a needlepoint receiving section (12A) on the inner layer portion (12) of the syringe needle cap (10). The outer circumference of a needle section (21B) on the tip of the prefilled syringe (20) is closely attached to a joining section (12B) on the inner layer portion (12) of the syringe needle cap (10), thereby securely sealing the inner space within the syringe needle cap (10) which covers the syringe needle (22). The outer layer portion (11) functioning as the cap main body of the syringe needle cap (10) is formed from a transparent resin, and the inner layer portion (12) is formed from a transparent elastomer as the interior material. As a consequence, the entire syringe needle (22) of the prefilled syringe (20), including the tip section, can be seen from the outside.

Abstract: A molded rubber article for sealing a container for storing medicinal chemicals comprising a fluorine resin film solidly covering the surface of the molded article which may contact with the chemicals. At least the surface of the bare rubber surface 300 which may contact with chemicals comprises a fluorine resin film layer 100, and a polyolefin film layer 200 is interposed between the fluorine resin film layer and the bare rubber surface. It can be preferably used as a rubber plug, a syringe gasket, a nozzle cap or an inside plug.

Abstract: The disclosed subject matter relates to an injection nozzle cap capable of being fittedly inserted in a space between an injection nozzle of a syringe having a cylindrical, female luer-lock fitting and the female luer-lock fitting. The injection nozzle cap can include a base portion and a cylindrical leg portion extending downwardly of the base portion. The cylindrical leg portion may include, on an outer wall thereof, a substantially annular, bulged portion and/or a ring. There can also be provided nozzle caps for pre-filled syringes, which can be securely and automatically capped at high speed on syringes having female luer-lock fittings without occurrence of their falling-off, for example, during filling of a drug solution.

Abstract: A sanitary container is molded from a plastic, for example, a cyclic olefin polymer or a hydrogenation product thereof. The plastic has been added with at least one pigment selected from the group consisting of C.I. Pigment Yellow 147, C.I. Pigment Yellow 180 and C.I. Pigment Yellow 181. The content of the at least one pigment may preferably range from 0.01 to 0.3 wt. % based the plastic.
