A kind of sealing cover of what is closed in this creation, includes a pedestal, a cover piece and a connection piece. The pedestal has one first room, first axis opening and one second axially open； The cover piece has an open end, an inlay card end and one second room； The connector system integrally extends the ora terminalis for being connected to the open end of the cover piece from the ora terminalis that the first axis of the pedestal is open, and there is a guide channel for being connected to first room and second room, the connector is bent to make the cover piece position the what pedestal by a positioning means. Thereby, this creation fitting what one is had to the opening of the container of flexible long tube, and bends that the connector is related to bend the flexibility long tube, then makes cover piece positioning what pedestal Hou, that is, can produce the effect of sealing. This creation further relates to a kind of liquid storaging device of the application sealing cover of what.本創作關於一種密封蓋，包括有一底座、一蓋件以及一連接件。該底座具有一第一容室、一第一軸向開口、以及一第二軸向開口；該蓋件具有一開口端、一嵌卡端以及一第二容室；該連接件係自該底座之第一軸向開口的一端緣一體延伸連接至該蓋件之開口端的一端緣，並具有一連通該第一容室與該第二容室的導溝，該連接件可彎折使該蓋件藉由一定位手段定位於該底座。藉此，將本創作套合於一具有撓性長管之容器的開口處，並彎折該連接件連帶使該撓性長管彎折，再使該蓋件定位於該底座後，即可產生密封的效果。本創作亦有關於一種應用該密封蓋的液體儲存裝置。
