A storage container includes a container body, an upper cover, a first thimble switch and a second thimble switch. The upper cover is installed at an opening above the container body. A first thimble switch is disposed on the upper cover, and is used to connect a first nitrogen delivery unit to deliver nitrogen. The second thimble switch is disposed at the bottom of the container body and is combined with the first weight sensing unit. A supply device that can be combined with the storage container includes a box body, a conveying pipe, a propulsion unit, a motor, and a first solenoid valve switch. The box is provided with a conduit for connecting a second thimble switch. The delivery pipe is disposed inside the container body and communicates with the conduit, and the delivery pipe has a nozzle opening downward. The propulsion unit is installed inside the conveying pipe. The motor is connected to the propulsion unit to drive the propulsion unit to move along the pipe diameter. The first solenoid valve switch is installed at the bottom of the box.一種保存容器，包括容器本體、上蓋、第一頂針開關及第二頂針開關。上蓋裝設在容器本體上方的開口。第一頂針開關貫設在該上蓋，用以連接第一氮氣輸送單元來輸送氮氣。第二頂針開關設置在容器本體底部並且結合第一重量感測單元。一種可結合該保存容器的供給裝置，包括箱體、輸送管、推進單元、馬達以及第一電磁閥開關。箱體設有導管以連接第二頂針開關。輸送管設置在容器本體內部並且連通至導管，輸送管具有向下開設的管口。推進單元裝設在輸送管內部。馬達連接推進單元以驅動推進單元沿著輸送管管徑移動。第一電磁閥開關裝設在該箱體底部。
