Abstract: A vacuum packaging system for transporting a plurality of medical containers includes a plurality of medical a tray that receives and supports the medical containers. The tray includes opposing first and second side walls, opposing side and rear walls and a bottom floor. The walls extend generally perpendicularly from the bottom floor of the tray to a top edge thereof. A nesting plate is removably mountable in the tray and includes a plurality of generally cylindrical sleeves each receiving one of the plurality of medical containers. A support surface within the tray generally extends parallel to and spaced a predetermined distance from the bottom floor of the tray and receives and supports the nesting plate. An air impervious flexible film defines an internal cavity and completely surrounds the tray and the medical containers. The internal cavity is evacuated to and maintained at a predetermined vacuum level below atmospheric pressure.

Abstract: A container unit for a drug is composed of a container, which is formed of a cylindrical drug-solution-containing portion and a drug-solution-filling neck portion, and a rubber closure for sealing the drug-solution-filling neck portion. The rubber closure comprises a disk-shaped head portion and a substantially cylindrical leg portion arranged on a lower wall of the head portion. The container is provided with a flat surface formed on a side of its inner wall at a boundary between the drug-solution-containing portion and the drug-solution-filling neck portion such that a lower end wall of the leg portion of the rubber closure can be brought into close contact with the flat surface, and at least a side wall of the drug-solution-containing portion forms a cornerless, rounded surface on a side where a drug solution is to be contained.

Abstract: A sealing stopper or piston for a syringe which includes a skirt part that is capable of serving as a backstop device, and a prefilled syringe using the same. The skirt part provides a backstop function, i.e. it prevents reverse movement of the piston, without increasing production costs.

Abstract: A syringe mold with a coolant circulation outward and homeward positioned close to the cavity space and a sufficient coolant circulating flow for cooling a core cylinder is provided. Slide cores (5, 5) are put in the position where the slide cores (5, 5) protrude from the circumference of the core cylinder (2) by moving the slide core operating jig (4) forward in the axial direction of the core cylinder (2) while cooling the core cylinder (2) by the coolant. Then, a two medical agent mixing type syringe having a communicating groove on the inner circumference for mixing two medical agents is injection-molded. A molding failure due to insufficient cooling of the core cylinder (2) can be prevented by positioning the coolant outward and homeward close to the cavity space and making the cross sectional area of the coolant outward and homeward enough large because the coolant outward and homeward is partitioned by the circumference of the jig container space in the core cylinder (2).

Abstract: To provide a syringe barrel and a syringe capable of allowing an operator to feel the amount of injected medical solution or the inserting distance of a piston by a difference in sliding resistance when an injection operation is performed. A syringe 1 includes a syringe barrel 11 which has an inner surface provided with a structure in which a sliding resistance F is changed step by step upon sliding a piston 32. The syringe barrel 11 includes steps which are formed at one or two or more positions of the inner surface in the axial direction so as to face from the rear end to the front end or from the front end to the rear end, and which include edges formed along the circumferential direction.

Abstract: A gasket 7 used for a prefilled syringe 1 in which liquid 3 is filled, having a constriction 8 on its circumferential side face in contact with an inner surface of a syringe barrel 2 and having a bottom face 7c which is not in contact with the liquid 3 whose circumference is formed in a tapered shape.

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: Provided is an easy-to-handle prefilled type nasal drip appliance which can spray medical solution surely into the nostril while holding down the production cost. A syringe barrel has a spray hole and a latching portion of a center stopper on one side, with a conduction portion of medical solution being provided at the latching portion, and has a portion protruding inward of the inner circumferential surface formed on the other end side. A plunger has a portion protruding outward of the outer circumferential surface formed substantially in the axial center wherein both protrusions engage with each other. When the plunger is moved in the spray direction of the syringe barrel to get over the plunger side protrusion and disengaged, the medical solution moves the center stopper in the spray direction to form a medical solution inflow groove between the conduction portion formed at the center stopper latching portion and the center stopper.

Abstract: A rubber-made syringe piston with a film laminated on it includes a plurality of annular ridges of different outer diameters formed continuously and integrally on a sliding surface of a liquid-contacting, leading end portion of the piston. The annular ridges may preferably be different by from 0.01 to 0.2 mm from one to another in outer diameter.

Abstract: Provided is a plunger assembly for a syringe in which a piston can be held at the leading end of a plunger rod without fault and the piston together with the plunger rod can be pulled out in an integrated manner even in the case in which a pulling out operation is carried out in order to fill with a medicinal solution in a syringe barrel by pulling out the piston with the plunger rod.
