Abstract: A prefilled syringe composed of a barrel having a luer tip at one end and an open proximal end, the barrel having at least a three layer structure of an innermost layer, an outermost layer, both made of a polyolefin resin, and an intermediate layer made of a resin with a barrier property and sandwiched by the innermost layer and the outermost layer. The barrel is produced through the sequential steps of: (a) injecting a specific amount of a polyolefin resin inside a cavity; (b) injecting a specific amount of a resin excelling in barrier property; (c) injecting a specific amount of the polyolefin resin again; and (d) separating the luer tip surface and an injection unit by pushing off a valve pin provided inside a valve gate or an inner nozzle of the injection unit, which injects the resin excelling in barrier property, toward the direction of the luer tip surface as desired.

Abstract: A PTP constructed so that when the PTP is divided into a section having one or a plurality of pocket portions, a person can discriminate between the top, bottom, right and left sides of this section in the planar direction and a visually handicapped person can correctly identify the direction of medicament identifying means provided on the section. The PTP includes a flexible sheet having a pocket portion containing a tablet T, and a metal foil adhered to the flexible sheet to hermetically seal the pocket portion containing the tablet T, and the PTP is dividable into sections including a plurality of pocket portions by a dividing line. An unevenness serving as medicament identifying means is provided on a top surface of a pocket portion, and arcs are respectively formed on the dividing line on the sides so that the shapes of all the divided sections become the same.

Abstract: An infusion bag which does not generate a significant number of fine particles in liquid contained in the bag, and has excellent transparency and flexibility, and also has sufficient heat resistance so that deformation does not occur even during sterilization at 115° C. A heat resistant sheet to form the infusion bag is formed from a polymer composition containing 50-70% by weight of a straight-chain polyethylene having a density of 0.928 g/cm3 or more and produced using a metallocene catalyst, 10-30% by weight of a low density polyethylene produced under high-pressure and 20-40% by weight of a straight-chain polyethylene having a density of 0.91 g/cm3 or less and produced using a metallocene catalyst.

Abstract: There is provided a liquid container capable of transferring liquids germ free in a simple manner within a short period of time and with inconsiderable solution remaining after transfer. The liquid container includes a vessel main body 1, a mouth portion 11 of which is closed by an easily breakable closing member 12, and a hollow needle member 2 crowned pivotably on the mouth portion 11 of the container main body 1. The closing member 12 is provided with a flat knob portion 121. A knob-containing portion 22 of the hollow needle member 2 is provided with a protrusion 24 for joining the knob portion 121 when the hollow needle member 2 is pivoted.

Abstract: A solution kit includes a prefilled syringe and a container containing a solvent charged therein. The prefilled syringe comprises a barrel provided at a distal end thereof with a tip closed by a twist-off type closing member, while the solvent container having a mouth portion closed by a twist-off type closing member. The tip of the prefilled syringe and the mouth portion of the solvent container are configured to engage with one another in liquid-tight engagement.

Abstract: To provide a plastic vessel containing an albumin preparation which completely restrains formation of thermally denatured albumin, a plastic molded member in a cylindrical shape is extruded in a molten state into opened dies, one end of which is closed in the dies, and a vessel is molded by blowing a compressed gas into the molded member in the dies or by bringing inner portions of the dies into a vacuum state. While the vessel is still disposed in the dies, an albumin preparation is introduced from an opening portion into an inner portion of the vessel and, therefore, the albumin preparation can be filled into the vessel in a sterilized state without being brought into contact with the atmosphere. Then, an opening portion of the vessel filled with the albumin preparation is hermetically sealed at an internal temperature of the opening portion of about 40 to 70° C. Thus formation of thermally denatured albumin can be completely restrained.
