The invention claimed is: 1. A spout assembly for a liquid container, comprising: a spouting member formed on an outlet of the container; a closer coupled on the spouting member having a spouting groove formed therein adapted to receive the spouting member; a male seal structure formed on the spouting member comprising a male seal projection extending, having a thickness which is less than a thickness of the spouting member from an outer circumference of the spouting member and an elastic seal projection extending from an inner circumference of the spouting member and adjacent the male seal projection; and a female seal structure formed on the closer, the female seal structure corresponding to the male seal structure and comprising an insertion groove extending from and parallel with the spouting groove and having a width which is less than a width of the spouting groove configured to receive the male seal projection from the spouting member and a lower end outer circumferential surface and circumferential seal wall configured adjacent the insertion groove to abut the elastic seal projection of the spouting member thereby sealing the liquid container. 2. The spout assembly of claim 1 wherein the elastic seal projection is inclined outward or inward, and the female seal structure comprises a seal wall tightly depressing the circumferential elastic seal projection. 3. The spout assembly of claim 1 wherein the female seal structure comprises a circumferential inclined wall for guiding the circumferential elastic seal projection. 4. The spout assembly of claim 1 further comprising a tamper-proof connected to the closer, the tamper-proof being provided with elastic projections and the spouting member being provided with hook projections, at least couple of distances between the elastic projections and the hook projections are different from each other so that the elastic projections can contact the hook projection with time differences when opening the closer. 5. The spout assembly of claim 4 wherein the tamper-proof is further provided with resistance projections and the spouting member is provided with elastic hook projections. 6. The spout assembly of claim 1 wherein a space is defined above an attaching portion of the spouting member, the attaching portion is attached on the inlet of the container. 7. The spout assembly of claim 1 wherein a straw is inserted in the spouting portion of the spouting member. 8. The spout assembly of claim 1 wherein the spouting member comprises a spouting guide member extending downward from an attaching portion that is attached on the inlet of the container. 9. The spout assembly of claim 1 wherein the spouting member is integrally formed with the container. 10. The spouting assembly of claim 1 wherein the spouting member is attached on the inlet of the container. 11. The spouting assembly of claim 1 wherein the container is formed of a paper pack or a film pouch. 12. The spout assembly of claim 1 wherein the male seal structure comprises the elastic seal projection formed on an upper end of a spouting portion or an inner wall defining the spouting portion.
