While containment the fluid-tight Characteristic of the medical application container, you joint the medical application container with the tube securely, preventing the foreign material mixture and the neutron leakage etc to the liquid which is stored inside the container, you offer the medical application dosage set which can expect satisfactory dosage medical therapy. On salient 160 of Funagata port 15, concatenated section through 1550a - 1550c, rib the seal section 155 which has 155a - 155c is formed. Each rib the slit 156a which communicates with channel 159 directly under 155a - 155c - 156c are provided. Each rib it fits 155a - 155c in fit section 2030of a connector, 20 - 2030c turns connector 20 in fluid-tight state, Funagata port 15 side locks. Concatenated section 1550a - 1550c are made to break with this operation, in fluid-tight state channel 159 is made to release inside connector 20.医療用容器の液密性を保持しつつ医療用容器をチューブと確実に接続し、容器内に貯留された液状物への異物混入や漏れ等を防止して良好な投与療法を期待できる医療用投与セットを提供する。舟形ポート15の突出部160の上に、連結部1550a~1550cを介してリブ155a~155cを持つ封止部155を形成する。各リブ155a~155cの直下に流路159と連通するスリット156a~156cを設ける。コネクター20の嵌合部2030a~2030cに各リブ155a~155cを嵌合させ、液密状態でコネクター20を回転させ、舟形ポート15側とロックする。この動作で連結部1550a~1550cを破断させ、液密状態で流路159をコネクター20の内部に解放させる。
