What is claimed is: 1. A device to lock a cover of a door shelf of a refrigerator, the door shelf having a main body and a cover hinged to the main body to selectively open the main body from the inside of the refrigerator, said device comprising: a seating unit having a seat and provided on the ma
What is claimed is: 1. A device to lock a cover of a door shelf of a refrigerator, the door shelf having a main body and a cover hinged to the main body to selectively open the main body from the inside of the refrigerator, said device comprising: a seating unit having a seat and provided on the main body; and a projection projecting perpendicular to a face of the cover, said seat being made of an elastic material to elastically engage with the projection, wherein an air channel is axially provided within the projection. 2. The device according to claim 1, wherein said seat is provided with a seating groove corresponding to said projection. 3. The device according to claim 2, wherein an outer diameter of the projection is slightly larger than an inner diameter of the respective seating groove. 4. The device according to claim 3, wherein the projection constricts in a radial direction such that the projection elastically engages with the corresponding seating groove. 5. The device according to claim 3, wherein the seating groove elastically expands in a radial direction such that the projection elastically engages with the corresponding seating groove. 6. The device according to claim 1, wherein said seat is provided with a seating hole corresponding to said projection. 7. The device according to claim 1, wherein said elastic material comprises silicone. 8. The device according to claim 1, wherein the projection is made of a hard material. 9. The device according to claim 1, wherein said seat is provided with a seating groove corresponding to said projection such that the projection elastically engages with the seating groove. 10. The device according to claim 9, wherein the air channel defines a sealing space along with the seating groove. 11. The device according to claim 10, wherein air in the sealing space generates a reverse force against the external force which is required to close the cover such that the reverse force has a magnitude which is proportional to an external force and instantaneously generated by air offsetting the external force to reduce impact energy. 12. The device according to claim 11, wherein when further external force is applied to the cover, air escapes from a sealing space formed by the elastic engagement of the projection with the corresponding seating unit such that the cover is completely closed without difficulty. 13. A device to lock a cover of a door shelf of a refrigerator, the door shelf having a main body and a cover hinged to the main body to selectively open the main body from the inside of the refrigerator, said device comprising: a seating unit having a seat and provided on the main body; and a projection projecting perpendicular to a face of the cover, said projection being made of an elastic material to elastically engage with the seat, wherein an air channel is axially provided within the projection. 14. The device according to claim 13, wherein said seat is provided with a seating groove corresponding to said projection. 15. The device according to claim 13, wherein said seat is provided with a seating hole corresponding to said projection. 16. The device according to claim 13, wherein said elastic material comprises silicone. 17. A device to lock a cover of a door shelf of a refrigerator, the door shelf having a main body and a cover hinged to the main body to selectively open the main body from the inside of the refrigerator, said device comprising: a seating unit having a seat and provided on the cover; and a projection projecting perpendicular to a face of the main body, said seat being made of an elastic material to elastically engage with the projection, wherein an air channel is axially provided within the projection. 18. The device according to claim 17, wherein said seat is provided with a seating groove corresponding to said projection. 19. The device according to claim 17, wherein said seat is provided with a seating hole corresponding to said projection. 20. The device according to claim 17, wherein said elastic material comprises silicone. 21. A device to lock a cover of a door shelf of a refrigerator, said door shelf having a main body and a cover hinged to the main body to selectively open the main body from the inside of the refrigerator, said device comprising: a seating unit having a seat and provided on the cover; and a projection projecting perpendicular to a face of the main body, said projection being made of an elastic material to elastically engage with the seat, wherein an air channel is axially provided within the projection. 22. The device according to claim 21, wherein said seat is provided with a seating groove corresponding to said projection. 23. The device according to claim 21, wherein said seat is provided with a seating hole corresponding to said projection. 24. The device according to claim 21, wherein said elastic material comprises silicone.
