Abstract: At a medicament manufacturer B, a mouth of a vial body 11 or syringe cartridge 51, in which a medicament 16 is sealed with a plug, is enclosed using a cap 15 or 50 under an environment of a predetermined cleanliness (for example, class M6.5 (the JIS method) or higher). In advance of this enclosure, the cap 15 or 51 has been manufactured at a container manufacturer A by molding with a molding material, which is free of any powdery material, under an environment having cleanliness not lower than the predetermined cleanliness. A cap for enclosing a mouth of a vial body or syringe cartridge sealed with a plug and a manufacturing method of the cap can be provided accordingly.

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 plunger kit for a medicine syringe provided with a syringe barrel includes a piston having an internal screw and a plunger rod having an external screw. The internal screw and external screw have a mutually non-complementary, basic groove profile and basic thread profile, respectively. A following flank of each thread of the external screw and a groove flank of a corresponding groove of the internal screw are formed such that, when the piston and plunger rod are slidably fit in the syringe barrel and the piston is then slid in a pull direction, the following flank can come into contact with the groove flank more strongly at a first part and more weakly at a second part to increase thread engagement strength between the external screw and the internal screw without any substantial expansion of the piston by the external screw.

Abstract: 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. The intermediate slide valve 10 equipped in the syringe 10 comprises an approximately cylindrical first elastic body 13 and an approximately cylindrical second elastic body 14 which is jointed with one bottom surface 13c of the first elastic body 13, the other bottom surface 13a of the first elastic body 13 and a side surface portion continued therefrom being laminated with a synthetic resin film 15 and the other bottom surface 14a of the second elastic body 14 and a side surface portion continued therefrom be laminated with a synthetic resin film 16.
