摘要:
Provided is a liquid container having a vacuum pumping device, which includes: a housing having a lower portion which is opened by means of an opening or closing control to be exposed to the atmosphere and an upper portion having a mounting hole so that a space is formed therein an inner container having a cylinder chamber provided at an upper portion thereof to allow a liquid to flow in or out and a liquid store area connected to a lower portion of the cylinder chamber to change a volume according to an amount of liquid therein, the cylinder chamber being coupled to the mounting hole of the housing so that the inner housing is detachably mounted in the housing for refilling a syringe unit coupled to or separated from the cylinder chamber to suck the liquid from the inner container and discharge the sucked liquid outwards and an elastic cap mounted to the cylinder chamber, the elastic cap being closed in advance when the syringe unit is inserted into the cylinder chamber and opened later when the syringe unit sucks the liquid after the syringe unit is inserted into the cylinder chamber, so that the liquid is discharged while keeping a sealed state. If the liquid container having a vacuum pumping device of the present disclosure is used, the elastic cap may be easily manufactured due to its simple design and may keep its sealing force even though it is used repeatedly. Further, since the movement of a membrane may prevent even a minimum air from flowing into a filling chamber of the liquid store area while the syringe unit is being inserted, it is possible to prevent the solution from being contaminated.
