The invention claimed is: 1. A method of manufacturing a gas displacement package containing food and gas other than air comprising the steps of: providing a container comprising a receptacle having an edge portion and a lid having an edge portion, wherein the edge portion of the receptacle overlaps with the edge portion of the lid so that the lid can cover a top of the receptacle, overlapped edge portions of the edge portion of the receptacle and the edge portion of the lid are sealed with an adhesive band tape, the container has a hole having an opening area of 0.3 to 3 cm2 with respect to a volume of the content of 1000 cm3 in the container, and the container contains air and food therein; expelling the air in the container through the hole so that the air can be displaced by and replaced with gas other than air; closing sealingly the hole with an adhesive label; and obtaining said gas displacement package containing food and the gas. 2. The method of manufacturing a gas displacement package as claimed in claim 1, wherein the container is made of plastic. 3. The method of manufacturing a gas displacement package as claimed in claim 1, wherein the container, the band tape and the adhesive label have a gas barrier property. 4. The method of manufacturing a gas displacement package as claimed in claim 1, wherein each of the receptacle and the lid has, at the edge portion, a flange including a horizontal portion horizontally extending from a opening, a substantial vertical portion vertically extending from an end of the horizontal portion and a ridge at a boundary between the horizontal portion and the vertical portion, among the vertical portions of the flanges, a vertical portion located inside with respect to the container is longer than a vertical portion located outside with respect to the container, the inside vertical portion has a step at a portion in contact with an end of the outside vertical portion, and the band tape is adhered over the step for sealing. 5. The method of manufacturing a gas displacement package as claimed in claim 4, wherein the vertical portion of the flange vertically extends downwardly from the horizontal portion. 6. The method of manufacturing a gas displacement package as claimed in claim 1, wherein the hole for gas displacement is provided on a top surface of the lid. 7. A package obtained by the method of manufacturing a gas displacement package accord to any one of claims 1-5. 8. The method of manufacturing a gas displacement package as claimed in claim 1, wherein the container is obtained by thermoforming a resin sheet. 9. The method of manufacturing a gas displacement package as claimed in claim 1, wherein the receptacle of the container has recesses at the flange thereof. 10. The method of manufacturing a gas displacement package as claimed in claim 1, wherein the band tape has elasticity of 3-150 Kg/mm2. 11. A method of manufacturing a gas displacement package containing food and gas other than air comprising the steps of: providing a container comprising a receptacle having an edge portion and a lid having an edge portion, wherein the edge portion of the receptacle overlaps with the edge portion of the lid so that the lid can cover a top of the receptacle, overlapped edge portions of the edge portion of the receptacle and the edge portion of the lid are sealed with an adhesive band tape, the container has a hole having an opening area of 0.3 to 3 cm2 with respect to a volume of the content of 1000 cm3 in the container, and the container contains air therein; filling the container with food; expelling the air in the container through the hole so that the air can be displaced by and replaced with gas other than air; closing sealingly the hole with an adhesive label; and obtaining said gas displacement package containing food and the gas.
