Document Type and Number:

WIPO Patent Application WO/2012/064062

Kind Code:

A2

Abstract:

The present invention relates to a liquid container provided with a vacuum pumping device. The liquid container provided with a vacuum pumping device of the present invention comprises: a housing, the lower portion of which has an opening for exposure to the air, and the upper portion of which has a mounting hole for creating an internal space; an internal container disposed in the housing, the mounting hole of the housing being coupled to an upper cylinder chamber, the lower portion of which is connected to a solution storage structure for the entry and discharge of liquid, wherein the volume of the solution storage structure varies according to the amount of liquid therein; a syringe means which is coupled to or separated from the cylinder chamber so as to draw the liquid from the internal container and discharge the drawn liquid outwards; and an elastic cap installed at the cylinder chamber, sealed in advance when the syringe means is inserted into the cylinder chamber, and opened afterward when the inserted syringe means draws liquid with a view to discharging same while maintaining air-tightness. According to the liquid container provided with a vacuum pumping device of the present invention, the structure of the elastic cap is simple, and thus ease of manufacturing and use is possible, and sealing force may be retained even after repeated use. In addition, during the insertion of the syringe means by means moving a plate membrane, even a minimal amount of air is prevented from entering a filling chamber of the solution storage structure, and thus the contamination of a solution may be prevented.
