Abstract (en)
[origin: JPS6430999A] PURPOSE: To obtain a cartridge provided with a fixed valve for use without danger by making top of boss concave radically extended from the center while diameter of the center opening of the axial boss of the valve is at least equal to 4 mm. CONSTITUTION: A circle internal connecting to the center opening 1e of valve 2 has at least diameter of 4 mm. Correspondingly, the circumferential lip 4b of the valve 4 has at least an inner diameter of 4.5 mm. And, the outer diameter of the boss 1c is at least equal to 10 mm. By this manner, as the center opening, valve co-acting with the opening, and other functional element have bigger diameters, even needle shifts a little from the center and pierces, but it can enter without damages. A both of the top of the boss 1c and the transverse sealing material 3 assumes the same concave shape, a good air sealing is obtained.
