| 20120118894 | PLASTIC CAP AND PRODUCTION METHOD THEREOF - Disclosed is a plastic cap useful for steadfastly maintaining a sealed state created in a container having a mouth with an opening by sealing the opening with a sealing member. The cap has a cap main body and a cover portion integrated with the main body via at least one bridge portion. The main body has a base portion and a top wall. The bridge portion is formed of a synthetic plastic filled in at least one fusion-bonding hole having a diameter of from 0.3 to 3 mm and arranged extending through at least one, preferably one of the main body or cover portion such that the main body and cover portion are integrally fusion-bonded by the bridge portion and the cover portion can be separated from the main body by breaking the bridge portion with hands. A production method of the plastic cap is also disclosed. | 05-17-2012 |
| 20120109076 | PISTON FOR SYRINGE HAVING VERY SMALL CAPACITY, AND PLUNGER HAVING THE PISTON MOUNTED THERETO - Disclosed are a piston for a micro-volume syringe and a plunger. The micro-volume syringe has a syringe barrel with a space defined in it. The piston is slidable on and along a wall of the space. A leading member to be arranged on a side where the piston comes into contact with a solution filled in the space and a trailing member to be arranged on a side where a plunger rod is to be connected, the latter side being opposite to a solution side of the leading member, have been integrated with each other. The trailing member has a higher hardness than the leading member. With the micro-volume syringe in which a drug solution can be filled in a very small quantity, the piston makes it possible to perform smooth drawing and ejection of the drug solution without leakage. Even if the small piston connected to a tip of the plunger rod is operated in a direction that the piston is to be pulled out of the syringe, the plunger rod does not slip off from the piston accidentally. The piston and plunger are optimal for the micro-volume syringe. | 05-03-2012 |
| 20120067888 | Rubber plug for a medical vial container - 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. | 03-22-2012 |
| 20120000881 | SYNTHETIC RESIN CAP AND METHOD OF MANUFACTURING SYNTHETIC RESIN CAP - At a medicament manufacturer B, a mouth of a vial body | 01-05-2012 |
| 20100305513 | SYRINGE AND SYRINGE BARREL - 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 | 12-02-2010 |
| 20100264139 | MOLDED RUBBER ARTICLE - 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 | 10-21-2010 |
| 20100258115 | Prefilled Type Nasal Drip Appliance - 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. Consequently, a medical solution storage portion and the spray hole are interconnected and the medical solution can be sprayed. | 10-14-2010 |
| 20100185157 | Plunger Assembly for Syringe - 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. | 07-22-2010 |
| 20100145284 | NEEDLE-EQUIPPED SYRINGE BARREL NEEDLE-EQUIPPED SYRINGE, AND MOLD AND METHOD FOR MOLDING SAME - There are provided a needle-equipped syringe barrel and a needle-equipped syringe in which a needle is suitably fixed to a syringe nozzle, and a mold and a method for molding thereof. A metal needle | 06-10-2010 |
| 20100106086 | SLIDE VALVES EQUIPPED IN A SYRINGE AND THUS EQUIPPED SYRINGE - There are provided an intermediate slide valve as well as a plunger slide valve equipped in a syringe in direct contact with injection liquids and a syringe equipped with such slide valves, the injection liquids nor valves being not affected with each other. | 04-29-2010 |
| 20100042055 | Syringe Piston - A rubber syringe piston in a generally cylindrical shape slidably mounted in a syringe barrel. The piston has a circular depression at an intermediate part thereof. R | 02-18-2010 |
| 20090288977 | Vacuum Package System - 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. | 11-26-2009 |
| 20090232932 | Syringe mold - 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. | 09-17-2009 |
| 20090139832 | Conveying Apparatus and Conveyed Object Inspection Apparatus - A conveying apparatus and a conveyed object inspection apparatus which can perform accurate, damage free image inspection. One conveying roller has a conveying surface formed in a spiral manner on an outer periphery surface thereof. The conveying surface is slanted with respect to the central axis narrowing toward other end side so as to convey a conveyed object while holding it between the conveying surface and other conveying roller. The other conveying roller has a tilt surface provided in a spiral manner on an outer periphery surface thereof. The tilt surface is slanted with respect to the central axis narrowing toward one end side. A feeding means can feed the conveyed object inbetween the conveying rollers. An inspection section has an image acquisition means capable of acquiring an image of an entire outer surface of the conveyed object, and an abnormality detecting means capable of detecting abnormality of the conveyed object based on the image A removing means can then remove an abnormal object. | 06-04-2009 |
| 20090100802 | VACUUM PACKAGE SYSTEM - A vacuum packaging system for transporting a plurality of medical containers includes a plurality of medical containers each having a head side and a base side and a tray that receives and supports the medical containers. The tray includes opposing first and second sidewalls, opposing front and rear walls and a bottom floor. The walls extend generally vertically from the floor of the tray. At least one platform generally extends parallel to the floor of the tray. An air impervious flexible film defines an internal cavity. The air impervious flexible film completely surrounds the tray and the medical containers and the internal cavity is evacuated to and maintained at a predetermined vacuum level below atmospheric pressure. One of the head side and the base side of each medical container contacts a top surface of at least one platform when the medical containers are positioned in the tray. | 04-23-2009 |
