ABSTRACT[Title of InventionjCONNECTOR SET FOR MEDICAL CONTAINERProvided is a connector set for a medical container that accurately connects a medical container to a tube in a liquid-tight manner and prevents contamination/leakage of a liquid substance in the medical container, thereby enabling satisfactory administration. Closure 155 having ribs 155a-155c is provided on protruding portion 160 of cap 15 via links 1550a---1550c. Slits 156a-156c that communicate with fluid passage 159 are provided immediately below ribs 155a-155c. After ribs 155a-1550 latch with recesses 2030a-2030c of nozzle 20, nozzle 20 is rotated and locked to cap 15 in a liquid-tight manner. As a result, hit101550a--1550c are broken, and fluid passage 159 is opened inside nozzle 20 in a liquid-tight manner so as not to come in contact with the outside.Fig. 2
