| 20090095647 | Injector Piston Nest - A container for receiving or storing or carrying pistons for injectors, the container having a base plate and hollow cylindrical piston storage parts (the container being hereafter referred to as a piston nest). Each of the hollow cylindrical piston receiving parts is formed either by making it vertically penetrate through the basic plate, with one side of the base plate functioning as one opening end, and project from the other side or by making it vertically penetrate through the base plate and project from both sides of the base plate. Preferably, each piston receiving part has a swelled part where a part of the inner peripheral wall surface of the piston receiving part is swelled inward. The pistons for injectors are received in the piston receiving parts. | 04-16-2009 |
| 20090131878 | PLUNGER ROD AND SYRINGE - A plunger rod useful for sliding a piston inserted in a syringe barrel has a threaded portion formed at an end of the plunger rod to attach the piston on the plunger rod and a flange formed at an opposite end of the plunger rod. The threaded portion and the flange are integrally connected together by a cylindrical member having an outer diameter such that the cylindrical member can be inserted with contact slidability in the syringe barrel, for example, an outer diameter equal to or slightly smaller than an inner diameter of the syringe barrel. | 05-21-2009 |
| 20090145876 | PLASTIC-MADE CAP FOR VIAL - A plastic-made cap for a vial having a lip, said cap being useful as a separation-preventing cap for a plug that seals up an opening of the vial, includes a top wall portion having an outer circumference and centrally defining an opening, and a cylindrical skirt portion extending downwardly from the outer circumference of the top wall portion and being open at its lower end. The skirt portion has an inner diameter (a) greater than an outer diameter (b) of the lip of the vial. The skirt portion is provided on its inner wall with plural ribs formed in a direction perpendicular to the top wall portion. The plural ribs are arranged in pairs at equal angular intervals between the respective pairs of ribs. Further, engagement claws are arranged between the respective pairs of ribs such that the engagement claws can be brought into engagement with an underside of the lip of the vial. | 06-11-2009 |
| 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 |
| 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 |
| 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 |
| 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 |
| 20100318036 | PLUNGER ROD AND SYRINGE - Disclosed is a plunger rod for a syringe. The plunger rod is useful for sliding a piston within a syringe barrel. The plunger rod is characterized in that it is colored in part or in whole. A syringe is also disclosed. According to such plunger rods, even plural syringes of exactly the same external appearance and configuration can be applied with features that make it possible to readily and visually identify them by simply taking a glance at their appearances without needing a measure such as applying indication members such as labels on them. Further, the use of such plunger rods makes it possible to provide syringes of significantly enhanced visual identifiability without impairing high-level quality, functions, sanitariness and safety required for the syringes. | 12-16-2010 |
