1. A vegetable container for a refrigerator, comprising: a case having an opening formed at a front thereof, the case being provided with a receiving space to receive objects to be stored;a drawer to seal an interior of the case;a discharge port formed through a bottom surface of the case to discharge water from the case;a negative pressure part to lower pressure in the case; andan opening and closing valve to open and close the discharge port,wherein the opening and closing valve is closed by a difference in pressure between an inside and an outside of the case and is opened when the difference in pressure between the inside and the outside of the case is released,wherein the opening and closing valve comprises:a fixing part having a space, through which water is collected, the fixing part being disposed in the discharge port; andat least two contact lips disposed at a lower part of the fixing part and come into contact with each other when there is a difference in pressure between the inside and the outside of the case,wherein the contact lips come into contact with each other to close the opening and closing valve when the pressure inside the case is lower than the pressure outside the case, andthe contact lips become spaced apart from each other to open the opening and closing valve when the difference in pressure between the inside and the outside of the case is released. 2. The vegetable container according to claim 1, wherein the discharge port comprises: a water collection part depressed in a portion of the bottom surface of the case; anda discharge part to allow the water collection part to communicate with an outside of the case. 3. The vegetable container according to claim 1, wherein the fixing part comprises: a catching protrusion caught by the discharge port; anda distance maintaining part connected to the contact lips to maintain a distance between the contact lips. 4. The vegetable container according to claim 3, wherein the distance maintaining part has at least two inclined surfaces, a distance between the at least two inclined surfaces which is gradually decreased from the catching protrusion to the contact lips. 5. The vegetable container according to claim 4, wherein the contact lips are disposed at lower ends of the inclined surfaces, andthe contact lips come into surface contact with each other. 6. The vegetable container according to claim 1, further comprising: a guide channel formed at an inner surface of the case to guide water formed in the case to the discharge port, whereinthe guide channel comprises:at least two mountain parts protruding toward an inside of the case; andat least one valley part disposed between the respective mountain parts, the valley part being depressed toward an outside of the case. 7. The vegetable container according to claim 6, wherein the mountain parts and the valley part are alternately arranged from the front to a rear of the case. 8. The vegetable container according to claim 7, wherein each of the mountain parts comprises a base and a first inclined side and a second inclined side extending from opposite ends of the base to form an apex, anda length ratio of the base, the first inclined side, and the second inclined side of each of the mountain parts is 1.4 to 1.6 : 1.9 to 2.1 : 2.36 to 2.64. 9. The vegetable container according to claim 1, further comprising: a top inner case disposed at an inside of an upper surface of the case, the top inner case being disposed between lateral surfaces of the case; anda top inner guide channel formed at an inner surface of the top inner case to guide water formed in the case to the discharge port, wherein the top inner guide channel comprises:at least two mountain parts protruding toward an inside of the case; andat least one valley part disposed between the respective mountain parts, the valley part being depressed toward an outside of the case,the mountain parts and the valley part being alternately arranged from the front to a rear of the case. 10. The vegetable container according to claim 9, wherein the top inner case comprises: a middle part located at a middle thereof;two inclined parts extending from the middle part to the lateral surfaces of the case while being inclined downward; andedge parts bent downward from the inclined parts such that the edge parts come into contact with the lateral surfaces of the case by elastic force. 11. The vegetable container according to claim 1, further comprising: a bottom inner case disposed at an inside of a lower surface of the case, the bottom inner case being disposed between lateral surfaces of the case; anda bottom inner guide channel formed at an inner surface of the bottom inner case to guide water formed in the case to the discharge port, wherein the bottom inner guide channel comprises:at least two mountain parts protruding toward an inside of the case; andat least one valley part disposed between the respective mountain parts, the valley part being depressed toward an outside of the case,the mountain parts and the valley part being alternately arranged from the front to a rear of the case. 12. A refrigerator comprising: a main body having a storage compartment;a cooling device to cool the storage compartment;a door to open and close the storage compartment; anda vegetable container mounted in the storage compartment of the main body, wherein the vegetable container comprises:a case having an opening formed at a front thereof, the case being provided with a receiving space to receive objects to be stored;a drawer to seal an interior of the case;a discharge port formed through a bottom surface of the case to discharge water from the case; andan opening and closing valve to open and close the discharge port,wherein the opening and closing valve is closed by a difference in pressure between an inside and an outside of the case and is opened when the difference in pressure between the inside and the outside of the case is released,wherein the opening and closing valve comprises:a fixing part having a space, through which water is collected, the fixing part being disposed in the discharge port; andat least two contact lips disposed at a lower part of the fixing part and come into contact with each other when there is a difference in pressure between the inside and the outside of the case,wherein the contact lips come into contact with each other to close the opening and closing valve when the pressure inside the case is lower than the pressure outside the case, andthe contact lips become spaced apart from each other to open the opening and closing valve when the difference in pressure between the inside and the outside of the case is released.
